Find the measure of angle CED in the figure below. Enter only the number.

Hey there!

3 * 2/3

= 3/1 * 2/3

= 3(2) / 1(3)

= 6 / 3

= 6 ÷ 3 / 3 ÷ 3

= 2 / 1

= 2 ÷ 1

= 2

Answer:

a. All of the whole - 10/10

b. A tenthof the whole - 1/10

Step-by-step explanation:

Step-by-step explanation:

a. since the entire whole represents a 100% , the number of whole that makes up for 100% is the 10 of the ten parts divided by 10 which is equal to 10.

b. since a whole equals 100% , if divided by 10 the entire 100% becomes 10% each for 10 parts. hence a single part equivalent to 1/10 is 10%

Answer:

Another method to graph a line in the xy-axis or xy-plane is to use its intercepts. What are intercepts? These are points of the line that are found on the xx and yy axes. There are two kinds of intercepts.

The first one is called the x-intercept because it is the point of the line located on the horizontal axis (x-axis).

The second is the y-intercept which is the point of the line located on the vertical axis (y-axis).

Answer:

-24/16, -√2, 21/51, 0.42

Step-by-step explanation:

Look at the signs of the numbers. Negative numbers will be on the left, while positive numbers will be on the right. That means -√2 and -24/16 will be on the left, while 0.42 and 21/51 will be on the right.

Part 1:

We can change the negative numbers to decimals to compare them.

-√2 ≈ -1.41

-24/16 = -1.5

-1.5 is smaller, which means the first number in the sequence will be -24/16 and then -√2.

Part 2:

We can also change the positive numbers to decimals to compare them.

0.42 = 0.42

21/51 ≈ 0.41

21/51 is a bit smaller, so the third number in the sequence will be 21/51 and then 0.42.

Step-by-step explanation:

Answer:

D. [tex]\frac{12x+20}{5y^3}[/tex]

Step-by-step explanation:

When multiplying 2 fractions, you multiply the numerators and denominators, so we have:

[tex](\frac{3x+5}{y^6})(\frac{4y^3}{5}) = \frac{(3x+5)\cdot 4y^3}{y^6\cdot 5} = \frac{(3x+5)\cdot 4}{y^3 \cdot 5} = \frac{12x + 20}{5y^3}[/tex]

Answer:

4th option

Step-by-step explanation:

[tex]\frac{3x+5}{y^6}[/tex] × [tex]\frac{4y^3}{5}[/tex] ( cancel y³ and [tex]y^{6}[/tex] on numerator/denominator by y³ )

= [tex]\frac{3x+5}{y^3}[/tex] × [tex]\frac{4}{5}[/tex]

= [tex]\frac{4(3x + 5)}{5y^3}[/tex]

= [tex]\frac{12x+20}{5y^3}[/tex]

The probability that at least one of the sides of the triangle is also a side of the octagon is 5/7

A regular octagon has 8 sides, and a triangle has 3 sides

Assume that there is a point on the triangle.

Then we select (3 - 1) points from the (8 - 1) sides.

8 - 1 = 7

3 - 1 = 2

So, the total number of selection is:

Selection = 7C2

Evaluate the combination expression

Selection = 21

Adjacent triangles have 5 lines (one line in common).

So, we have:'

n = 5 - 1

n = 4

The number of ways this points can be selected is:

Selection = 4C2

Evaluate

Selection = 6

The probability that the triangle and the octagon do noth have the same side is:

P= 6/21

The probability that at least one of the sides of the triangle is also a side of the octagon is calculated using the following complement rule

P = 1 - 6/21

Evaluate the difference

P = (21 -6)/21

P = 15/21

Reduce fraction

P = 5/7

Hence, the probability that at least one of the sides of the triangle is also a side of the octagon is 5/7

Step-by-step explanation:

Given:

7x + 10 < 11x + 2

To Find:

Solve and graph on a number line. Show your work in the box below.

Solve:

Subtract 10 from both sides

7x + 10 -10 < 11x + 2-10

Simplify

-4x < - 8

Multiply both sides by -1 which reverse the inequality

Simplify

4x > 8

Now, Divide both sides by 4

4x ÷ 4 > 8 ÷ 4

Simplify

x > 2

Solution: x > 2

Now graphing:

> means greater than

that means x is greater than 2

Thus, the line is going to the right.

Graph below:

Answer: x > 2

Step-by-step explanation:

7x+ 10 < 11x + 2

7x+10-10 < 11x + 2 -10

7x < 11x -8

7x - 11x < 11x -8 - 11x

Deducing from the considered box plot, the number of crates that weigh more than 99.5 pounds is 330 approx.

A box plot has 5 data description.

When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.

Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.

Left to right is said in assumption that data was arranged increasingly from left to right

We're specified here that:

Total 440 crates is being shipped by company.

The box plot is defined by the points 84, 99.5, 113, 143, 170

The point 99.5 is the first quartile.

There are 75% observations on its right, so 75% of 440 is the number of crates which weigh greater than 99.5 pounds.

We get this value as:

[tex]\dfrac{440}{100} \times 75=330[/tex]

Thus, deducing from the considered box plot, the number of crates that weigh more than 99.5 pounds is 330 approx.

The amount of money which is expected to lose if the game of spinner is played 1000 times is $111.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

You spin the spinner two times.

Answer:

y=-4/3x-4

Step-by-step explanation:

The equation of the line that is perpendicular to the line which has a slope of 3 / 4 and passes through the point ( 0, - 4 ) is equals to [tex]y= \frac{-4}{3} x-4[/tex]

" Equation of line is defined as the equation which represents the set of points using slope."

Formula used

[tex]y=mx+c[/tex]

m = slope of the line

c = y-intercept

Product of the Slopes of perpendicular lines  = -1

According to the question,

Slope of the given line = [tex]\frac{3}{4}[/tex]

Using condition for slope of perpendicular lines we have,

Slope of the line perpendicular to the given line 'm' = [tex]\frac{-4}{3}[/tex]

From given point (0, -4)

Y- intercept 'c' = -4

Substitute the value in the formula to get equation of required line,

[tex]y= \frac{-4}{3} x-4[/tex]

Hence,  equation of the line that is perpendicular to the line which has a slope of 3 / 4 and passes through the point ( 0, - 4 ) is equals to [tex]y= \frac{-4}{3} x-4[/tex].
