Find the exterior angle measure

Answer:

13

Step-by-step explanation:

the top angle is 45°, and then there is the 90° angle, so the other angle must also be 45°. this makes it a right isosceles triangle, so both legs must be equal (they are both 13)

Answer:

hope this helpful

Step-by-step explanation:

isosceles right

because A light ray incident at 90° at the first face emerges at the same angle. The diagram shows five isosceles right-angled prisms. A light ray incident at 90° at the first face emerges at the same angle with the normal from the last face.

Answer:

x = 32°

Step-by-step explanation:

The consecutive angles in a parallelogram are supplementary.

∠ A and ∠ D are consecutive angles, then

131 + 17 + x = 180

148 + x = 180 ( subtract 148 from both sides )

x = 32°

Answer:

It is clear that both equations are identical. Hence, the solution to the system of equations would contain infinitely many solutions.

Step-by-step explanation:

Given the system of equations

y = -4x + 2

y = -4x + 2

It is clear that both equations are identical. We know that when the system of equations is identical, then the system of equations will have infinitely many solutions.

Hence the given system of equations would contain infinitely many solutions.

solving the system of equations

[tex]\begin{bmatrix}y=-4x+2\\ y=-4x+2\end{bmatrix}[/tex]

Substitute y = -4x+2

[tex]\begin{bmatrix}-4x+2=-4x+2\end{bmatrix}[/tex]

For y = -4x+2

Express y in terms of x

[tex]y=-4x+2[/tex]

Thus, the solution to the system of equations would be:

[tex]y=-4x+2,\:x=x[/tex]

It is clear that x = x is true no matter what. Hence, the solution to the system of equations would contain infinitely many solutions.

For x/2 to be greater than or equal to 10, you must try out a few numbers.

If x = 20...

x/2 greater than or equal to 10

= 20/2 greater than or equal to 10

= 10 greater than or equal to 10.

So the answer for x is:

x = 20 or more

Answer: $1.75

Step-by-step explanation:

Answer:

1) 4.2 inches

2) 63 inches²

Step-by-step explanation:

If the base is 15 inches, we can assume that the opposite side is also 15 inches. 15 + 15 = 30. If we subtract 30 from the total perimeter, we will have the sum of the last two sides.

38.4 - 30 = 8.4

Now that we have the sum we can now find the exact length with division:

8.4/2 = 4.2 inches

To find the area, we multiply these together.

4.2 * 15 = 63

Answer:

Yes, it is a linear equation. This equation is in y=mx+b form, which is a linear equation. To rearrange it into y=mx+b form, you'll just do y= -2x+8

To make a line, you only need two points, so here are two points that fit into the line of y= -2x+8:

(0,8) and (1,6)

The area of the circle is around 908 square centimeters, so the correct option is A.

The area of a circle of radius R is given by:

A = pi*R²

Where pi is an irrational number, and we can write it as pi = 3.14

Here we can see that the radius of the circle is 17cm, then we can replace that in the area formula to get:

A = 3.14*(17cm)² = 908 cm²

Then the corret option is A.

Answer:

V≈653

Step-by-step explanation:

In order to find the volume of a cylinder, you use the formula V=πr2h. In this case, the filled-in formula would be V=3.14*4*4*13. This equals 653.45. In your answer, you need to round to the nearest whole number. In this case, round down to 653. That is your answer. Hope this helps :)

Answer:

653in

Step-by-step explanation:

Radius = 4

Height = 13

Volume = 653

Bottom and top Surface Area = s (50 for 1) (100 is both)

Total Surface Area

= 13 + 50 + 50 = 100 + 2(100) = 100(13+4)

Answer:

32 pounds of almonds

Step-by-step explanation:

Let the number of pounds of almond be a while that of cashews be c

we want to make a total of 80 pounds

Thus;

a + c = 80 ••••••••(i)

Furthermore;

Let us work with the costs

Costs of a pounds of almonds will be ;

a * 2.5 = 2.5a

cost of c pounds of cashews

c * 3.25 = 3.25c

Total cost at which they sell will be 80 * 2.95 = 236

Thus;

3.25c + 2.5a = 236 •••••(ii)

From i, c = 80-a

Put this into ii

3.25(80-a) + 2.5a = 236

260-3.25a + 2.5a = 236

0.75a= 24

a = 24/0.75

a = 32

Answer: It would have to be something that adds up to 180.

Step-by-step explanation:

like if angle 1 is 118 you would add (x) to get to 180.

30 by 30 = 900cm²

2.9m by 2.9m = 8.41m²

take m² change to cm²

10,000cm² = 1m²

8.41 × 10000 = 84100cm²

84100 ÷ 900

Answer:

1. 5

2. [tex]\sqrt{85}[/tex]

3. [tex]\sqrt{26}[/tex]

Step-by-step explanation:

1. just count the units: 5 units

2. Find the slope = rise/run = -7/6

you now have a right triangle, one side is 7 units (from the rise), and the other is 6 units (from the run)

use the pythagorean theorem to find the hypotenuse.

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]7^{2} + 6^{2} = c^{2}[/tex]

49 + 36 = [tex]c^{2}[/tex]

85 = [tex]c^{2}[/tex]

[tex]\sqrt{85} = \sqrt{ c^{2}[/tex]

[tex]\sqrt{85} = c[/tex]

Simplify the radical, but [tex]\sqrt{85}[/tex] is farthest that it can go, so that is the answer.

3. same process as 2

slope = -1/5

[tex]1^{2} + 5^{2} = c^{2}[/tex]

1 + 25 = [tex]c^{2}[/tex]

26 = [tex]c^{2}[/tex]

[tex]\sqrt{26} = c[/tex]

That is the farthest it can go, so that will be the answer.

Answer:

For the first question:

[tex]\sqrt{\frac{15x}{x^3}}\\= \sqrt{\frac{15}{x^2}}\\= \frac{\sqrt{15}}{x}\\[/tex]

And the second

[tex]\frac{\sqrt{x^2}}{\sqrt{x^3}}\\= (x^2)^{\frac{1}{2} }(x^3)^{\frac{-1}{2} }\\= x^1 \times x^{\frac{-3}{2} }\\= x^{\frac{2}{2}} \times x^{\frac{-3}{2} }\\= x^{-\frac{1}{2}}\\= \frac{1}{\sqrt{x}}[/tex]

Answer:

[tex] \sqrt{ \frac{15x}{ {x}^{3} } }= \sqrt{ \frac{15}{ {x}^{2} } } = \frac{ \sqrt{15} }{ \sqrt{ {x}^{2} } } = \frac{ \sqrt{15} }{x} \\ [/tex]

[tex] \frac{ \sqrt{ {x}^{2} } }{\sqrt{{x}^{3}}} = \frac{ {x}^{ \frac{2}{2} } }{ {x}^{ \frac{3}{2}}}= \frac{x}{ {x}^{(1 + \frac{1}{2}) } } = \frac{x}{x \times {x}^{ \frac{1}{2} } } = \frac{1}{ \sqrt{x} } \: \\ [/tex]
