Let's split our shapes up to help us solve these problems. I will do A, and allow you to apply these skills learned to B.

Look for any shapes that you may be able to split the overall shape into. In this case, we can split the overall shape into a rectangle and a triangle. We can find the area of both of these shapes and then add them.

The rectangle has length 10 and width 8. Thus, its area is 8*10 = 80.

The triangle has base 4 (Subtract the 8 from the 12) and height 4 (Subtract the 6 from the 10). Thus, its area is (1/2)(4)(4) = 8.

We can now add these areas to get a total area of 88 units^2.

This is the right table my bad. Need the equation

Hi, seems like the answer is f(x) = x - 4 Edit: this was my original answer, but I was apparently completely out of my mind when I wrote it. The correct answer is f(x) = -4x + 50, as I stated below. I'm very sorry for any trouble I caused

The manager of a grocery store reports that there is a 12 percent chance that a customer buys apples during a shopping trip, a 5

Ivanshal [37]

Answer:

The probability of a customer buying carrots is 0.10.

Step-by-step explanation:

Here, given:

P (Customer buying apples) = 12%

⇒ P(A) = 12 \100 = 0.12

P(Customer Buying apples AND Carrots) = 5%

⇒ P(A ∩ C ) = 5 /100 = 0.05

P(Customer buying apples OR carrots ) = 17%

⇒ P(A∪ C) = 17/100 = 0.17

Now, we know that:

Now, here substituting the values, we get:

P(A∪ C) = P(A) + P(C) - P(A ∩ C )

⇒ 0. 17 = 0.12 + P(C) - 0.05

or, 0.17 - 0.07 = P(C)

or, P(C) = 0.10

or, P(Customer Buying Carrots) = 0.10

Hence, the probability of a customer buying carrots is 0.10.

What is the measure of an anglethat is supplementary to an angle of 37°? A. 127° B. 53° C. 143° D. 323°

KengaRu [80]

<u>Answer:</u>

143°

option c is correct!

<u>Explanation:</u>

Given:

Two angles are supplementary:

One angle = 37°

We know if two angles are supplementary their sum is equal to 180°.

Let another angle be x°

= > 37° + x° = 180

= > x° = 143°

Therefore another angle is 143°.

Help math homework both questions

-Dominant- [34]

Answer:

Q-12 The vertical length of the top part of elevator to ground is 0.8484 meters .

Q -14 The glide runway path is 24,752.47 feet .

Step-by-step explanation:

Q - 12

Given as :

The diagonal length of the elevator = e = 1.2 meters

The vertical length of the top part of elevator to ground = x meters

The angle made by elevator with ground = Ф = 45°

<u>Now, According to figure</u>

Sin angle = $\dfrac{\textrm perpendicular}{\textrm hypotenuse}$

Or, Sin Ф = $\dfrac{\textrm x}{\textrm e}$

Or, Sin 45° = $\dfrac{\textrm x meters}{\textrm 1.2 meters}$

Or, 0.707 × 1.2 meters = x

∴ x = 0.8484 meters

So, The vertical length of the top part of elevator to ground = x = 0.8484 meters

Hence,The vertical length of the top part of elevator to ground is 0.8484 meters . Answer

Q-14

Given as:

The altitude of decent of plane = H = 10,000 feet

The angle of descend = Ф = 22°

Let the glide runway path = y feet

<u>Now, According to question</u>

Tan angle = $\dfrac{\textrm perpendicular}{\textrm base}$

Or, Tan Ф = $\dfrac{\textrm H}{\textrm y}$

Or, Tan 22° = $\dfrac{\textrm 10,000 feet}{\textrm y feet}$

Or, 0.4040 = $\dfrac{\textrm 10,000 feet}{\textrm y feet}$

Or, y = $\dfrac{\textrm 10,000 feet}{\textrm 0.4040}$

∴ y = 24,752.47

So,The glide runway path = y = 24,752.47 feet

Hence, The glide runway path is 24,752.47 feet . Answer
