The expression 61+x when x = 18 evaluates to 79.

Expression is a combination of numbers, symbols and operators that represent a mathematical quantity or operation.

To find the value of the expression, we must first substitute 18 in for x.  To evaluate this expression, we must add 61 and 18. 61+18 = 79. Therefore, the expression 61+x when x = 18 evaluates to 79.

To verify the answer, we can use the distributive property of multiplication to expand the expression. 61+x is equivalent to 61+18, which can be written as

61+18 = 61+1*18.

We can now distribute the 1 to the 18,

so 61+1*18 = 61+18 = 79.

Therefore, the expression 61+x when x = 18 evaluates to 79.

Question: Evaluate-61+x

Enter your answer in the box.

Find the value of equation, when x = 18.

Para resolver este problema, primero tenemos que multiplicar las fracciones:

3/5 x 4/7 = 12/35

Luego, encontramos cuántas docenas son 12/35 de 420 docenas:

(12/35) x 420 = 144

Así que 3/5 de 4/7 de 420 docenas (que es equivalente a 12/35 de 420 docenas) representa 144 docenas de huevos.

Para encontrar el número total de huevos, multiplicamos 144 docenas por 12 huevos por docena:

144 x 12 = 1,728

Por lo tanto, 3/5 de 4/7 de 420 docenas representa 1,728 huevos.

Answer:

Ratios are fractions, right? Set the two fractions equal to each other and then cross-multiply them. If each side of the equation is equal, then the ratios are equal; if not, then the ratios are not equivalent.

Ex. 1

Comparing ratios 4:2 and 2:1

[tex]\frac{4}{2} = \frac{2}{1}[/tex]

Cross-multiplying, we get 4 = 4, but we can also simplify each side of the equation to get 2 = 2.

Ex. 2

Comparing ratios 3:5 and 6:7

[tex]\frac{3}{5} =? \frac{6}{7}[/tex]

Cross-multiply, we get 21 = 30, so the ratios are not equal. This is an example of a case where you can't simplify the ratios.

Ex. 3

Comparing rations 5:12 and 10:24

[tex]\frac{5}{12} = \frac{10}{24}[/tex]

Cross-multiply, 120 = 120 so the ratios are equal.

The percent decrease in the number of people who went to the local swimming pool over four weeks, starting with a record high of 1,060 people in the first week, was 20%.

To find the percent decrease in the number of people who went to the pool over the four weeks, we need to first find the total number of people who went to the pool over the four weeks and then calculate the percentage decrease from the first week to the fourth week.

Number of people in the first week = 1,060

Number of people in the second week = 1,060 - 110 = 950

Number of people in the third week = 950 + 130 = 1,080

Number of people in the fourth week = 1,080 - 232 = 848

Total number of people over the four weeks = 1,060 + 950 + 1,080 + 848 = 3,938

Percentage decrease in the number of people who went to the pool over the four weeks = ((1,060 - 848)/1,060) * 100% = 20%

Therefore, the percent decrease in the number of people who went to the pool over the four weeks is 20%.

Step-by-step explanation:

There are (9+8+7)  = 24 parts  that add up to 144

each part is then 144/24 = 6

then each side is    9 parts =  9*6 = 54

                8 parts = 8 * 6 = 48

       7 parts    7 * 6 = 42

Step-by-step explanation:

1st method:-

Using congurency:-

In ∆AOC AND ∆COD

1) CO= CO {common side}

2) <OAC = <ODC { inscribed angel on same base CO}

3)OD = OC {radius}

4)∆AOC ≅ ∆COD {SAS fact}

5)∆AOC = ∆ COD {area of congurent traingle is equal}



2nd method:-

Using property of traingles:-

Construction:- Join DA and CB

<ACB = 90° { angle substended by diameter}

CO⊥AB

Now we know that,

Area of traingle = 1/2 B*H

CO is height { of both traingle's}

AO is base {of both traingle's}

Now, ∆AOC= 1/2*CO*AO--1

and, ∆ COD = 1/2 *CO*AO--2

∆AOC= ∆COD {from above 1 and 2}

To the total of 99 cookies, there are 27 cookies in middle pile.

Let's call the number of cookies in the first pile "x". Then, the number of cookies in the second pile is 1/2 of x, or (1/2)x, and the number of cookies in the third pile is 1/3 of x, or (1/3)x.

We know that the total number of cookies is 99, so we can write an equation:

x + (1/2)x + (1/3)x = 99

To solve for x, we can first find a common denominator:

(6/6)x + (3/6)x + (2/6)x = 99

(11/6)x = 99

x = (6/11) * 99

x = 54

So, there are 54 cookies in the first pile, (1/2)x = (1/2)*54 = 27 cookies in the second pile, and (1/3)x = (1/3)*54 = 18 cookies in the third pile. In the middle pile there are 27 cookies.

The cost of 4 kilograms is $13 if the unit rate is $3.25kg.

What is the unit rat?

The unit rate is a rate in which the second term in the ratio is 1. For example, if you have a rate of 60 miles per hour, the unit rate would be 60 miles per 1 hour, or simply 60 miles per hour. Another example is if you have a unit price of $2.50 per pound of apples, the unit rate would be $2.50 per 1 pound, or simply $2.50 per pound.

If the unit rate is $3.25/kg, then the cost of 1 kg is $3.25. To find the cost of 4 kg, we can multiply the cost of 1 kg by 4:

4 kg x $3.25/kg = $13

Step-by-step explanation:

You want to know the amount that has a tax of $0.72 when the tax rate is 6%.

The tax is computed by multiplying the price by the tax rate.

  tax = price × (tax rate)

  $0.72 = price × 0.06

  price = $0.72/0.06 = $(72/6) = $12

The original price of the bracelet is $12.

The length of the midsegment of the trapezoid is 38.5. The midsegment is the line segment that connects the midpoints of the two parallel sides of the trapezoid. It divides the trapezoid into two congruent triangles.

To find the length of the midsegment of the trapezoid, we need to first find the midpoint of the two parallel sides of the trapezoid. To do so, we need to use the midpoint formula, which is (x1 + x2) ÷ 2, (y1 + y2) ÷ 2, where (x1, y1) and (x2, y2) are the coordinates of the two points.

For example, if the coordinates of the two points are (1,2) and (5,7), then the midpoint of the two points will be (1+5) ÷ 2, (2+7) ÷ 2 = (6, 4.5).

Once we have the coordinates of the two midpoints, we can use the distance formula to find the length of the midsegment. The distance formula is √((x2-x1)² + (y2-y1)²).

So if the coordinates of the two midpoints are (3,6) and (9,2), then the length of the midsegment will be √((9-3)² +(2-6)²) = √(36+16) = √52 = 38.5.

Based on my knowledge, I would expect a negative correlation between the amount of gas in a car's gas tank and the total distance the car has traveled since last being filled with gas.

As the car travels, the amount of gas in the tank decreases. Thus, if the car has traveled a long distance since being filled up, it is likely that there is less gas in the tank. Therefore, there should be a negative correlation between the amount of gas in the tank and the distance traveled, meaning that as the distance traveled increases, the amount of gas in the tank decreases.

A scatter plot of these two variables should show a downward-sloping trend, indicating the negative correlation.

what is equation ?

An equation is a mathematical statement that asserts that two expressions are equal. In other words, an equation says that one expression on the left side of the equals sign is the same as the expression on the right side of the equals sign. An equation typically includes variables

In the given question,

To determine the equation of the line passing through the points (0,-3) and (2,0), we can use the slope-intercept form of a linear equation:

y = mx + b

where m is the slope and b is the y-intercept.

The slope of the line can be found using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

where (x₁, y₁) = (0,-3) and (x₂, y₂) = (2,0)

m = (0 - (-3)) / (2 - 0) = 3/2

So the equation of the line is:

y = (3/2)x - 3

Now we can check which ordered pair is a solution to this equation by plugging in the x and y values into the equation and seeing if it holds true.

A. (0,-3)

y = (3/2)x - 3

-3 = (3/2)(0) - 3

-3 = -3

This is true, so (0,-3) is a solution.

y = (3/2)x - 3

0 = (3/2)(2) - 3

0 = 0

This is true, so (2,0) is a solution.

y = (3/2)x - 3

2 = (3/2)(2) - 3

2 = 0

This is false, so (2,2) is not a solution.

D. (-3,0)

y = (3/2)x - 3

0 = (3/2)(-3) - 3

0 = -9/2

Therefore, the surface area of the given triangular prism is approximately 126.56 square units.

Surface area is a measure of the total area that the surface of a three-dimensional object occupies. It is the sum of the areas of all the faces or surfaces of an object. Surface area is usually expressed in square units, such as square inches, square centimeters, or square meters, depending on the unit system being used.

For example, if you have a cube with side length "s", its surface area can be calculated by finding the area of each face and adding them together. Since a cube has six square faces of equal size, the formula for its surface area would be:

Surface Area of Cube = 6s²

by the question.

To find the surface area of a triangular prism, we need to calculate the area of all its faces and then add them together.

First, let's find the area of the two triangular bases. Each base is a right triangle with base 5, height 4, and hypotenuse 7. We can use the Pythagorean theorem to calculate the height of the triangle:

[tex]4^2 + (5/2)^2 = h^2[/tex]

[tex]16 + 6.25 = h^2[/tex]

[tex]22.25 = h^2[/tex]

[tex]h = \sqrt(22.25)[/tex]= 4.71

So, the area of each base is:

[tex]A = 1/2 * base * height = 1/2 * 5 * 4.71 = 11.78[/tex]

Next, we need to find the area of the three rectangular faces. The two congruent rectangular faces have dimensions of 5 by 6, and the remaining rectangular face has dimensions of 7 by 6. The area of each rectangular face is simply the product of its dimensions:

[tex]A1 = 5 * 6 = 30[/tex]

[tex]A2 = 5 * 6 = 30[/tex]

[tex]A3 = 7 * 6 = 42[/tex]

Finally, we can calculate the total surface area of the prism by adding up the areas of all five faces:

[tex]Total surface area = 2A(base) + A1 + A2 + A3[/tex]

[tex]Total surface area = 2(11.78) + 30 + 30 + 42[/tex]

The probability of the first three cards being 3 aces and the last one being a king is 1/66,300.

The probability of drawing an ace from a deck of 52 cards is 4/52 (since there are 4 aces in the deck), and the probability of drawing a king is 4/52 as well.

Since the cards are dealt with no replacement, the probability of drawing three aces in a row is

(4/52) × (3/51) × (2/50) = 1/5525

This is because after each card is drawn, there is one less ace in the deck, and one less card overall.

Now, we need to multiply this probability by the probability of drawing a king as the fourth card. Since there are only 48 cards left in the deck at this point (since three cards have already been drawn), the probability of drawing a king is

4/48 = 1/12

Therefore, the probability of drawing 3 aces and 1 king in a row is
