Question 2: Please help I do not understand this question.
Svetradugi [14.3K]

The measurement of AB is 16.23.

Solution:

Given ACB is a right angled triangle.

AC = 10, ∠C = 90° and ∠A = 52°.

cos θ ≈ 0.616

Here AC is the base and AB is Hypotenuse.

To find the length of AB:

$\cos\theta=\frac{\text{Base}}{\text{Hypotenuse}}

$\cos 52^\circ=\frac{10}{AB}

$0.616=\frac{10}{AB}

Do cross multiplication, we get

$AB=\frac{10}{0.616}

AB = 16.23

Hence the measurement of AB is 16.23.

4(1.5c+6)-2c=-9 I need a help my teacher doesn't help
harkovskaia [24]
4(1.5c+6)-2c=-9 so we distribute the 4 to 1.5 tand 6 and it will now be broken into this ==>   6c+24-2c=-9 ok now we most combine like terms so the we do 6c-2c= 4c so the problem is now 24-4c=-9 ok now i think we need to solve for c so we subtract 24 to -9  because it is negative it is now -33 so the problem is -4c=-33 divide by -4 and you will get your answer. I hope this helped and is correct.

A party rental company has chairs and tables for rent. The total cost to rent 3 chairs and 2 tables is $18. The total cost to re
DerKrebs [107]
C= chair cost
t= table cost

Create two equations with the given information. Solve for one variable in equation one. Substitute that answer in equation two. Then you can solve for the needed information.
3c+2t=$18
5c+6t=$48

3c+2t=18
Subtract 2c from both sides
3c=18-2t
Divide both sides by 3
c=(18-2t)/3

Substitute the value for c in equation two:
5c+6t=$48
5((18-2t)/3)+6t=48
(90-10t)/3+6t=48
Multiply everything by 3 to eliminate fraction
(3)((90-10t)/3)+(3)(6t)=(3)(48)
90-10t+18t=144
90+8t=144
Subtract 90 from both sides
8t=54
Divide both sides by 8
t=$6.75 cost for table

Substitute the t value to solve for c:
3c+2t=18
3c+2(6.75)=18
3c+13.50=18
3c=4.50
c=$1.50 chair cost

Check:
5c+6t=$48
5(1.50)+6(6.75)=48
7.50+40.50=48
48=48

Hope this helps! :) If it does, please mark as brainliest.
