Sergeeva-Olga [200]

Answer:

A. a + c ≥ 70; 15a + 4c ≤ 1000

Step-by-step explanation:

<u>Given data:</u>

A community action committee is planning a block party

The party will be successful if at least 70 adults (a) and children (c) attend

Their budget for the party is $1,000

The cost for each adult will be $15

And the cost for each child will be $4

<u>Solution:</u>

<u />

At least 70 adults and children attend.

So the inequality here is a + c ≥ 70

The budget for the party is $1,000.

So the cost for all adults plus the cost for all children cannot exceed $1,000

And hence the inequality here is; 15a + 4c ≤ 1,000

What are the solutions to<br> (m +11)2 = 64?

mel-nik [20]

Answer:

(21 + 11)2 = 64

So, I don't think teachers do this, but this is my way of doing it

Okay, so first, I divided 64 by 2 :

64 ÷ 2 = 32

Then, I subtracted 11 from 32:

Now, to check, just do the problem :

(21 + 11)2 = 64

32 * 2 = 64

Please Help! (Math)(tanβ)

sertanlavr [38]

Answer:

<u>Find the missing side first.</u>

x = $\sqrt{12^2 - 7^2} = \sqrt{144 - 49} = \sqrt{ 95}$

1) tangent = opposite leg / adjacent leg

tanβ = √95/7
Correct choice is B

2) sine = opposite leg / hypotenuse

sinβ = √95/12
Correct choice is D

Which of the following is not a way to represent the solution of the inequality 2(x + 1) greater than or equal to 20?

Goshia [24]

Answer:

option C

A number line with a closed circle on $9$ and shading to the left

Step-by-step explanation:

we have

$2(x+1)\geq 20$

solve for x

$2x+2\geq 20$

Subtract $2$ both sides

$2x+2-2\geq 20-2$

$2x\geq 18$

Divide by $2$ both sides

$x\geq 9$ --------> is equivalent to $9 \leq x$

The solution is the interval--------> [9,∞)

All real numbers greater than or equal to $9$

A number line with a closed circle on $9$ and shading to the right
