3r^2 if r = 1/6 can someone help me please.

Answer:

Step-by-step explanation:

The teacher has 7/8 pounds of clay given.

gives out 1/16 per station

7/8= 0.875 pound

7/8 / 1/16 pound= 14 maximum stations

14 stations divided by 2 classes = 7 in each room

Answer:

9 cans of soup and the 4 frozen dinners were purchased

Step-by-step explanation:

Let x represent the number of cans of soup purchased.

Let y represent the number of frozen dinners purchased.

Lincoln purchased a total of 13 cans of soup and frozen dinners. This means that

x + y = 13

Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium. The 13 cans of soup and frozen dinners which he purchased collectively contain 4450 mg of sodium. This means that

250x + 550y = 4450 - - - - - - - - -1

Substituting x = 13 - y into equation 1, it becomes

250(13 - y) + 550y = 4450

3250 - 250y + 550y = 4450

- 250y + 550y = 4450 - 3250

300y = 1200

y = 1200/300

y = 4

Substituting y = 4 into x = 13 - y, it becomes

x = 13 - 4 = 9

Answer:

1,2,4

Step-by-step explanation:

I just took the test and got it right and its the only logical answer.

If ΔXYZ, after reflection and dilation by a scale factor of 1/2, ΔX'Y'Z' is created, the following would be true:

1. △XYZ ~ △X'Y'Z'

2. AngleXZY ≅ AngleY'Z'X'

4. XZ = 2X'Z'

Thus, if ΔXYZ, after reflection and dilation by a scale factor of 1/2, ΔX'Y'Z' is created, the following would be true:

1. △XYZ ~ △X'Y'Z'

2. AngleXZY ≅ AngleY'Z'X'

4. XZ = 2X'Z'

Answer:

  21.8 cm

Step-by-step explanation:

A useful way to write the Law of Sines relation when solving for side lengths is ...

  a/sin(A) = b/sin(B)

Then the solution for 'a' is found by multiplying by sin(A):

  a = sin(A)(b/sin(B)) = b·sin(A)/sin(B)

__

We need to know the angle A. Its value is ...

  A = 180° -75° -31.8° = 73.2°

Then the desired length is ...

  a = (22 cm)sin(73.2°)/sin(75°) ≈ (22 cm)(0.9573/0.9659)

  a ≈ 21.8 cm

_____

I like to use the longest side and largest angle in the equation when those are available. That is why I chose 75° and 22 cm.

Answer:

16.21 degrees

Answer:

B. 73°

Step-by-step explanation:

The triangle is an isosceles triangle as it has 2 equal sides. This implies that the angles opposite to the two equal sides are of the same measure.

Therefore,

x = (180 - 34) ÷ 2

x = 146 ÷ 2

x = 73°

Step-by-step explanation:

The inverse functions “undo” each other, You can use composition of functions to verify that 2 functions are inverses. When you compose two inverses… the result is the input value of x. 3 3 g x x = Because f(g(x)) = g(f(x)) = x, they are inverses.

[tex]g(9) = \frac{2048}{3}[/tex]

Step-by-step explanation:

Given

[tex]g(x) = \frac{1}{6}(8)^{x-5}[/tex]

[tex]x = 9[/tex]

Required

Solve

Substitute 9 for x in [tex]g(x) = \frac{1}{6}(8)^{x-5}[/tex]

[tex]g(9) = \frac{1}{6}(8)^{9-5}[/tex]

[tex]g(9) = \frac{1}{6}(8)^{4}[/tex]

Remove bracket

[tex]g(9) = \frac{1}{6}* 8^4[/tex]

[tex]g(9) = \frac{1}{6}* 4096[/tex]

[tex]g(9) = \frac{1* 4096}{6}[/tex]

[tex]g(9) = \frac{4096}{6}[/tex]

Simplify fraction

[tex]g(9) = \frac{2048}{3}[/tex]

Answer:

y = -x + 1

Step-by-step explanation:

y=mx+b

m:slope= rise/run, the line goes down 1 and over 1 so it would be -1/1 which is -1

b:y-intercept: the line crosses the y-axis at 1

plug in m=-1 and b=1 into y=mx+b

y=-1x+1

y=-x+1

Step-by-step explanation:

Answer:

Yes, they are similar.

[tex]AB\approx 127.3947[/tex]

Step-by-step explanation:

Part 1)

Yes.

First, ∠D and ∠B are both right angles, so they are congruent.

Next, ∠DCE and ∠BCA are vertical angles. So, their measures are congruent.

Then by Angle-Angle Similarity, we acquire:

[tex]\Delta EDC\sim \Delta ABC[/tex]

Part 2)

The corresponding sides of similar triangles are proportional.

Therefore:

[tex]\displaystyle \frac{DE}{DC}=\frac{AB}{BC}[/tex]

By substitution:

[tex]\displaystyle \frac{103}{76}=\frac{AB}{94}[/tex]

Cross-multiply:

[tex]76AB=9682[/tex]

So:

[tex]AB=9682/76\approx127.3947[/tex]

Answer:

112 ft.

Step-by-step explanation:

This shape is a trapezoid. To find the area of a trapezoid, use the formula: [tex]\frac{b_{1} + b_{2} }{2} h[/tex]. First find base one. The shape in the middle is a square, so the top side of the trapezoid will be worth 8 ft as well. Now add the two bases 8 + 20 to get 28 and then divide by 2 to get 14. Now multiply 14 by the height (8). 14 x 8 is 112 ft.

Answer:

The function [tex]y = x[/tex] is shifted downwards by 8 units

Step-by-step explanation:

Given

[tex]y = x[/tex]

Required

Determine the transformation that gives: [tex]y = x-8[/tex]

When a function f(x) is shifted by b units, the new function g(x) is g(x) = f(x) - b

In this case:

[tex]y = x[/tex]

[tex]b = 8[/tex]

So, the new function is:

[tex]y = x - b[/tex]

Substitute 8 for b

[tex]y = x - 8[/tex]

Hence, the function is shifted 8 units downward
