Answer:

Do not listen to the other answer! Here is how you solve that.

Step-by-step explanation:

For the semicircle, here is the formula for area: A= \frac{1}{2}(\pi r^2)

For the triangle, here is the formula for area:A=\frac{1}{2}(bh)

Then, add.

So,

Triangle:

A=\frac{1}{2}(9*12)

A=54

Semicircle:

A=\frac{1}{2}(\pi 6^2)

A=18\pi

Your answer is Area = 54 + 18\pi

The width of a rectangle is 1 3/4 feet. The rectangle is 2 1/2 feet longer than it is wide. What is the length of the rectangle?
sp2606 [1]

Answer:

length=4 1/4

Step-by-step explanation:

  1. 1 3/4 + 2 1/2
  2. convert 2 1/2 into 2/4 since 2 is half of 4
  3. add the converted number and 1 3/4 fractions
  4. 2/4 and 3/4 added will make 1 1/4
  5. add 1 1/4, 2 and 1 and it will equal 4 1/4

Which expression is equivalent to 5 (w 4) when w = 9? 5 (9) 9 (5) 5 (9) 4 5 (9) 20.
pogonyaev

Expression consists of numbers, variables, and mathematical operations. The expression f(w)=5(w+4) is equal to f(9)=5(9)+20.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The expression is given to you is,

f(w)= 5(w+4)

Now, if we solve the expression it can be written as,

f(w)=5w+20

substituting the value of w, we will get,

f(9)=5(9)+20

Hence, the expression f(w)=5(w+4) is equal to f(9)=5(9)+20.

Solve each inequality and graph its solution.
ra1l [238]

Answer:

8) No solution

9) n > -5 <em>(View explanation for info on how to graph)</em>

Step-by-step explanation:

<em><u>Question 8</u></em>

<em><u /></em>

<u>24+6k < -6(-4-k)</u> - Solve and graph

1) Distribute -6 to -4 and -k:

24+6k < 24+6k

2) Subtract 6k from both sides:

24<24

^ We know the following is false, therefore there is no solution to question 8.

<em><u>Question 9</u></em>

<em><u /></em>

<u>-2n-40 < 5(6+n)+7n</u> - Solve and graph

1) Distribute 5 to 6 and n:

-2n-40 < 30+5n+7n

2) Combine alike terms:

-2n-40 < 30+12n

3) Add 2n to both sides:

-40 < 30+14n

4) Subtract 30 from both sides:

-70 < 14n

5) Divide both sides by 14:

n > -5

6) To graph, plot an OPEN CIRCLE (<em>don't fill in the circle)</em> at point -5 and then draw an arrow pointing to the right!

Let me know if you need any help with the others :)
