Answer:

The rectangle that we could use to find the area of the yellow triangle, is a rectangle of length = 12cm and a width = 8 cm. (A image of this can be seen below).

Remember that:

The area of a rectangle of length L and width W is:

A = W*L

The area of a triangle rectangle with catheti a and b is:

A = a*b/2

Then the area of the rectangle of length = 12cm and width = 8cm is:

A = 12cm*8cm = 96 cm^2

Now we need to subtract twice the area of a triangle rectangle of catheti a = 8cm and  b = 6cm

(one cathetus is 6cm because is exactly half of the length of the rectangle)

The area of each one of these triangle rectangles is:

A' = 8cm*6cm/2 = 24cm^2

The area of the yellow triangle will be:

A = A - A' = 96cm^2 - 2*24cm^2 = 48cm^2

Answer: [tex]45-48\ \text{mph}[/tex]

Step-by-step explanation:

Given

Car velocity is given by [tex]45, 46, 46, 45, 48[/tex]

The range of a given set of data is given by

[tex]\text{Range=Max-min. value}[/tex]

Maximum velocity=48

Minimum velocity=45

The Range of velocity is

[tex]\Rightarrow 48-45=3[/tex]

Velocity lies between [tex]45-48\ \text{mph}[/tex]

You don't need help my dude, you already have all of the right answer. Good job!!!

Answer:

non-linear i'm pretty sure

Step-by-step explanation:

Answer:

2 < x < 24

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides , that is

13 - 11 < x < 13 + 11

2 < x < 24

Answer:

Step-by-step explanation:

Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side. For example 30° , −330° and 390° are all coterminal.

Answer:

Step-by-step explanation:

Coterminal angles have a difference of 360° or multiples of 360°.

Negative coterminal angle with 30° is:

Answer:

-46

Step-by-step explanation:

2x+43=2x-3

We simplify the equation to the form, which is simple to understand

2x+43=2x-3

We move all terms containing x to the left and all other terms to the right.

+2x-2x=-3-43

We simplify left and right side of the equation.

0x=-46

0=-46

The left and right sides are not equal, therefore there is no solution. This equation is invalid.

Answer:

DNE

Step-by-step explanation:

The the given table, we have;

As x approaches -14 from the left, at x = -14.001,  p(x) = 1.96

[tex]\lim \limits _{x \to -14^{-}} p(x) = 1.96[/tex]

As x approaches -14 from the right, at x = -13.999, p(x) = 1.97

[tex]\lim \limits _{x \to -14^{+}} p(x) = 1.97[/tex]

The value of p(x) when x = -14 is [tex]\lim \limits _{x \to -14} p(x)[/tex] = Undefined, or is not definable, therefore, p(x) Does Not Exist (DNE) when x = -14, and we have;

[tex]\lim \limits _{x \to -14} p(x)[/tex]  Does Not Exist, DNE.

Answer:

120cm³

Step-by-step explanation:

The volume of a rectangular prism is the length multiplied by the width and height. You may not have multiplied correctly or multiplied all of the dimensions.

So, let's multiply our dimensions, 4cm × 6cm × 5 cm.

4 · 6 · 5 = 120

4 times 6 equals 24, then 24 times 5 is 120.

The volume of the box, then, is 120cm³. Remember to use the ³ (cubed) sign for volume.

Good luck :)

Answer:

6+6=12 cm

4+4=8 cm

6+6= 12 cm

Add all together and it equals 32

Complete Question

A peanut butter cookie recipe calls for 3 1/2 cups of flour to make 6 dozen cookies. How many cups of flour must be used to make 20 dozen?

Answer:

11 2/3 cups of flour

Step-by-step explanation:

From the above question:

6 dozen = 3 1/2 cups of flour

20 dozen = x

Cross Multiply

6 dozen × x = 20 dozen × 3 1/2 cups of flour

x = 20 dozen × 3 1/2 cups of flour/6 dozen

x = 20 × 7/2 /6

x = 140/2 ÷ 6

x = 140/2 × 1/6

x = 140/12 cups of flour

x = 11 8/12

= 11 2/3 cups of flour

Therefore, 11 2/3 cups of flour must be used to make 20 dozen.

Answer: V = 600 unit 2

Step-by-step explanation:

We have that

the volume of the rectangular pyramid is

V = (1/3) BH

where

B is the area of the rectangular face

H is the height of the pyramid

step 1

Find out B

B = (15)(10) unit 2

step 2

Find the volume

B = 150 unit 2

H = 12 unit

substitute

V = (1/3)(150)(12)

V = 600 unit 2

I hope this help you! :)

Answer:

Step-by-step explanation:

First note that the triangles shown are isosceles triangles due to equality of two of their sides which is radius. So their baseline angles are equal

Since their middle angle are equal too, so their 3 angles are the same. It menas both triangles are similar.

However, we know two of three sides are equal, but the third should be also because of their similarity.

y+4 = 2y - 3

2y - y = 4 - 3

y = 4+3

y = 7

Therefore,

2y-3 = 2.7-3 = 14-3 = 11

Answer is 11 centimeters
