Step-by-step explanation:

The difference in ages of Marcelle and Megan is 95/12 as an improper fraction and as a mixed number is 7 whole number and the fraction 11/12.

We shall convert the fractions to have similar denominators and simply apply subtraction for the numerators as follows:

Marcelle's age = 15 whole number, 1/2

Marcelle's age = 31/2

Megan's age = 7 whole number, 7/12

Megan's age = 91/12

LCM of 2 and 12 is 12 so;

Marcelle's age = 31/2 × 12/12

Marcelle's age = 186/12

difference in their age (186 - 91)/12

difference in their age = 95/12

Therefore, the difference in the ages of Marcelle and Megan is the fraction 95/12 or as a mixed number is 7 whole number and the fraction 11/12

For Quadratic equation, It is possible to know if there are 2 real solutions by examining the discriminant that is [tex]b^2-4ac[/tex] of the equation [tex]ax^2+bx+c[/tex].

In mathematics, a solution refers to a value or set of values that satisfies a given equation, system of equations, or problem. For example, if the equation is x + 2 = 4, then the solution is x = 2, because substituting 2 for x in the equation makes it true. In the case of systems of equations or more complex problems, a solution may be a set of values that satisfies all the equations or conditions of the problem. In such case, the solution may be represented graphically or as coordinates of a point.

In mathematics, an ideal solution refers to a solution that meets all the desired criteria or requirements without any constraints. It is the "best case" scenario. A real solution, on the other hand, refers to a solution that takes into account all the limitations and constraints of a problem. It is a more practical and realistic solution.

No, isosceles triangles are not always 180 degrees. The sum of the interior angles of an isosceles triangle is 180 degrees, but the individual angles can be different.

Isosceles triangles do not necessarily have a 180-degree angle. Any triangle with two equal sides is said to be isosceles. Any triangle's internal angles add up to 180 degrees. An isosceles triangle's individual angles can change depending on how long its sides are, though. An isosceles triangle, for instance, might have a third side that is longer or shorter than the other two sides if the first two sides are equal. The size of the inner angles will be impacted by this. As a result, an isosceles triangle need not have angles that are 180 degrees. An isosceles triangle has interior angles that add up to 180 degrees, but the individual angles might vary.

Answer:

Step-by-step explanation:

Consider the following:

a) y=0.25x+7

b) $10.75

Explanation:

a)

y=mx+b is the slope-intercept form.

B is our Y intercept meaning any fee or initial charge that adds to total cost. In this situation, the initial fee of $7 is our Y-Intercept. . Our mx is the slope. A slope increases based on the amount (x) of certain things you have. In this situation, you are buying maybe 1, 2 or 3 tickets and each ride costs $0.25.

Our x remains the same, that is where we plugin the amount of tickets we will buy (x). The M value is the price per ticket which as said, is $0.25 per. Our slope therefore will be 0.25x.

Combining our Y-Intercept and our Slope will leave us with y (total cost) = 0.25x + 7

b)

We have found our slope, 0.25x+7

Now, we have to plugin our number of rides (x) which is 15.

If done correctly it should be 0.25(15)+7 and that is equal to $10.75 for 15 rides.

Answer:

B

Step-by-step explanation:

Remark

If you started at W and went all the way around the circle until you wound up back at W, you will have gone 360 degrees. Since the angle measurement that prevents that is 85 degrees, the answer must be 360 - 85 = 275.

Answer:

275

Step-by-step explanation:

The angle start in V then goes the left to Y and ends in W

First you add the First 34 degrees from V to U.

Then the 90 degrees from U to Y. (you can see it has a square on the angle therefore its 90).

After that you add another 36 degrees from Y to X.

Finally to get the unknown angle from X to W you subtract all the other angles from 360 degrees.

360-245=115

Then add all the angles and you get 275 degrees.

Answer:

Total flour used = 3 1/6 c

Step-by-step explanation:

Whole wheat flour = 1 1/2 c

Buckwheat flour = 1 2/3 c

How much flour did he use in all?

Total flour used = Whole wheat flour + buckwheat flour

= 1 1/2 c + 1 2/3 c

= 3/2 c + 5/3 c

= (9c + 10c) / 6

= 19c/6

= 3 1/6 c

Total flour used = 3 1/6 c

First, we need to find what numbers 5 and 7 both go into, and are 2-digits.

5 and 7 go into the numbers 35 and 70.

So, that means the amount of numbers 5 and 7 go into and are 2-digits is Two Numbers.

2.

Now, we have to find the amount of numbers 5 goes into and the amount of numbers 7 goes into, and they need to be 2-digits.

5 goes into the numbers 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, and 95. -- 18 numbers

7 goes into the numbers 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, and 98. -- 13 numbers.

n(A) = 18   n(B) = 13

Now, the set of 2-digit numbers that are multiples of both 5 and 7 is given by

A∩B = {35, 70}   ⇒  n(A∩B) = 2

Therefore, the number of 2-digit numbers that are multiples of either 5 or 7 is given by

n(A∪B) = n(A) + n(B) - n(A∪B) = 18 + 13 - 2 = 29

Now, there are 90 2 -digit numbers.

Thus, the number 2-digit numbers are multiples of neither 5 nor 7 is

90 - 29 = 61.

Hence, the total number of numbers is 61.

Answer:

y = 4x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (1, 3) ← 2 ordered pairs from the table

m = [tex]\frac{3+9}{1+2}[/tex] = [tex]\frac{12}{3}[/tex] = 4 , then

y = 4x + c ← is the partial equation

To find c substitute any ordered pair from the table into the partial equation

Using (1, 3 ) , then

3 = 4 + c ⇒ c = 3 - 4 = - 1

y = 4x - 1 ← equation of line

Answer:

x = 70 degrees

Step-by-step explanation:

Answer:

x = 70°

Step-by-step explanation:

Because it is an isosceles triangle, the two base angles are the same (55° and 55°)

All triangles angles must add up to 180°, so 180-55-55 will give us the missing angle (x).

180-55-55 = 70

x = 70°

A 2-step problem is a mathematical problem that can be solved using two steps or operations. These types of problems are typically simple and can be solved using basic arithmetic or algebraic concepts.

For example, a 2-step problem could involve solving for one variable in one equation and then substituting that value into another equation to find the value of a second variable.

For example:

2x+3y=10 and 3x-2y=5

Here, first step would be to solve for x in the first equation by isolating x and in the second step we can substitute that value of x in the second equation to solve for y.

It can also refer to a problem that can be solved in two steps by breaking the problem down into simpler parts. For example, a 2-step problem in geometry could involve finding the area of a shape by first finding the area of one part of the shape and then adding that to the area of another part of the shape.

In general, 2-step problems are not complex and can be solved easily by breaking down the problem into simpler parts and solving each part separately.

The area of rectangle with side whole number = ab sq. units,

and area of rectangle with fraction side = ac/bd sq. units.

A quadrilateral with four right angles is a rectangle. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal (360°/4 = 90°). A square is a rectangle with four equally long sides.

Given  to find the area of rectangle,

Area of rectangle is given by product of length and width.

A = l x b

Let the dimensions of a rectangle are all whole numbers, a by b

Area = a x b

A = ab sq. units

another rectangle with dimensions all fractions say, a/b by c/d .

Area = a/b x c/d

A = ac/bd sq. units

After solving, the smallest number of yellow marbles are 4.

In the given question, all of Marcy's marbles are blue, red, green, or yellow.

One third of her marbles are blue, one fourth of them are red, and six of them are green.

We have to find the smallest number of yellow marble.

The 6 green marbles and yellow marbles of the total marbles = 1 - (1/3) - (1/4)

The 6 green marbles and yellow marbles of the total marbles = 5/12

Now, suppose the total number of marbles is x

We know the number of yellow marbles is 5/12 x-6 and a positive integer.

Therefore, 12 must divide x

Trying the smallest multiples of 12 for x.

We see that when x = 12

We get there -1 yellow marbles, which is impossible.

However, when x = 24 here are

= 5/12 x - 6

= 5/12*24 - 6

= 4
