Which of the following shows the correct process for finding the area of the shape shown below?​

Answer:

54

Step-by-step explanation:

Since triangle ABC ~ DEF

Angle A = Angle D

Angle A = 54

Answer:

the anwser is d

Step-by-step explanation:

Here we are given that C is between A and B.

So using the midpoint rule, sum of whole length AB will be addition of lengths AC and BC

Hope that helps

Answer:

AC Or CA

Step-by-step explanation:

So, this is what a b and c would look like on a number line:

A----C----B

However, we dont know exactly what these variables are. THey could be somerthing like this:

A------------------C-B

But this doesnt matter.

If we look at the first numberline, A and C make up the first half of the numberline.

C to B make up the later half.

AB is the total numberline.

SO tecnically, A to C+ C to B = AB

Or:

AC + CB = AB

This can also be seen in the second numberline.

A to C make up almost all of the numberline.

C to B make up a smll amount.

But in the end, AC + CB will still make AB.

Hope this helps you! :D

ANSWER IS B

Step-by-step explanation:

5x - 3 = 3x + 1

5x - 3x = 1 + 3

2x = 4

x = 4/2

x = 2

Answer:

B. 2

Step-by-step explanation:

The sides 5x - 3 and 3x + 1 are the same length, so you can put an equal sign: 5x - 3 = 3x + 1, x = 2:

5(2) - 3 = 3(2) + 1

10 - 3 = 6 + 1

7 = 7

So x is 2

Answer:

1,645 poles

Step-by-step explanation:

Here, we want to calculate the total number of poles

We can have an arithmetic progression here

Where the last term is the 58 piles , the first term is the top layer which is 12 and the common difference between the piles is 1

Firstly, we calculate the number of stacks which can be obtained using the nth term formula;

Tn = a + (n-1)d

58 = 12 + (n-1)1

58 = 12 + n - 1

58 = n + 11

n = 58-11

n = 47

So we have the stack high up to 47 units

So, using the sum of terms in an arithmetic sequence formula, we have;

Sn = n/2 ( a + L)

where a is the first term 12 and L is the last term 58

Thus, we have

Sn = 47/2( 12 + 58)

Sn = 47/2 * 70

Sn = 1,645

Answer:

Slope of line B: 1/3

Step-by-step explanation:

To find a slope perpendicular to another slope, you take its negative reciprocal.

Therefore, line B will have a slope of 1/3 because -3 -> -1/3 -> 1/3

The phrases best describes the line that passes through the points (5, -7) and (a, -4) is rise from left to right.

Coordinates are two numbers (Cartesian coordinates), or sometimes a letter and a number, that locate a specific point on a grid, known as a coordinate plane. A coordinate plane has four quadrants and two axes: the x axis (horizontal) and y axis

As, we locate this coordinate in graph we can see the line will either rise from left to right or falls from right to left.

Hence, line that passes through the points (5, -7) and (a, -4) will rise from left to right.

Answer:

540 jumps in 9 minutes.

Step-by-step explanation:

60 jumps a minute. Chen is fast, but we need to find how many jumps in 9 minutes.

Let's say one minute is m

m = 60

9m = 60x9

We do x9 because from m to 9m you need to multiply by 9, so lets do that on both sides.

9m = 540

9 minutes = 540 jumps

Answer:

6

Step-by-step explanation:

The worst scenario is that of a slight possibility, the first 5 balls you took are completely different color. The chance of this happening is tiny, but if you want to be sure, then you should consider about it.

But, after taking out the sixth ball, you can be sure that the ball, now right on your hand, must share a same color with at least one of the balls you took out, since there are only five colors.

because 20+30 =50 players and we keep the ratio equivalent since we multiplied by the same number.

Answer:

4x + 5y = 20

Step-by-step explanation:

4x + 5y = 20

5y = -4x + 20      (Subtract 4x to isolate 5y. Put the 4x in front of the 20)

y = [tex]-\frac{4}{5}x[/tex] + 4         (Divide all by 5 to isolate y)

And then it's done and in slope-intercept form

[tex]-1< -\frac{4}{5} < 0[/tex]        or [tex]-\frac{4}{5}[/tex] is greater than -1 but less than 0

Answer:

A 99.96%

Step-by-step explanation:

The z score shows by how many standard deviations the raw score is above or below the mean. The z score is positive if the raw score is above the mean while the z score is negative if the raw score is below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ z=z-score,\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation\\\\For\ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }[/tex]

The probability can be gotten from the normal distribution table. Therefore from the normal table:

P(z < 3.37) = 0.9996 = 99.96%

Answer:

1/2

Step-by-step explanation:

y2 - y1 / x2 - x1

-3 - 3 / -6 - 6

-6 / -12

= 1/2

We want to find the slope of a line given that we know that the line passes through the points (6, 3) and (-6, -3).

We will find that the slope is: 1/2

A general line can be written as:

[tex]y = a\cdot x + b[/tex]

Where a is the slope and b is the y-intercept.

If the line passes through the points (x₁, y₁) and (x₂, y₂) then we can write the slope as:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

We know that our line passes through (6, 3) and (-6, -3), then the slope of our line will be:

[tex]a = \frac{-3 - 3}{-6 - 6} = \frac{-6}{-12}[/tex]

Now to simplify this, we know that:

-12 = 2×(-6)

Replacing that in the above equation we get:

[tex]a = \frac{-3 - 3}{-6 - 6} = \frac{-6}{-12} = \frac{-6}{2\cdot -6} = \frac{1}{2}[/tex]

Then the slope written as a simplified fraction is:

a = 1/2

Answer:

x = 5.1

Step-by-step explanation.

Our first step is to find all the angles. If b = 91 degree and c is 38, a. has to be 51 because all triangles add up to 180 degree. Because we have both B and b, we can use sine law.

a/A     13/sin91      c/38

we can use b in this situation.

The legnth  of a is 10.1.

So,  x-5 would be 5.1

Answer:

x = 9 or x = -9

Step-by-step explanation:

The parameters of the given points are;

The location of the point T = (0, 7)

The location of the point U = (x, -5)

Then distance between points T and U = 15 units

The distance between points A and B, 'd', given their coordinates, A(x₁, y₁) and B(x₂, y₂) is found using the following formula;

[tex]d=\sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

Therefore, for the given points, T(0, 7) and U(x, -5), we get;

[tex]15 = \sqrt{\left ((-5) - 7 \right )^{2}+\left (x - 0 \right )^{2}}[/tex]

Squaring both sides, gives;

[tex]15^2 = \left ((-5) - 7 \right )^{2}+\left (x - 0 \right )^{2}} = (-12)^2 + x^2[/tex]

∴ x² = 15² - (-12)² = 81 = 9²

x² = 9²

∴ x = ±√(9²) = ± 9

The possible values of x are x = 9 or x = -9

Step-by-step explanation:

She has 52 cards per deck, and b decks.

This means she has 52b cards.

How this works:

For 1 deck, she has 52 cards, or 52×1 cards.

For 2 decks, she has 104 cards, or 52×1 cards.

For 5 decks, she has 260 cards, or 52×5 cards.

For 10 decks, she has 520 cards, or 52×10 cards.
