please hurry find the measure of S
Answer:
m∠S = 29.5
Explanation:
Q
S [tex]\huge\boxed {\sf \triangle}[/tex] R
In this triangle, QR = SQ, which means its an isosceles triangle, angle S and R is similar.
Thus solve:
m∠S = (180° - 121°)/2
m∠S = 29.5°
∆QRS is isosceles
QR=SQSo
<Q=<S=121°

How can the fraction completed in one hour be found?The fraction of the fence completed in [tex]\mathbf{\frac{3}{4}}[/tex] of an hour = [tex]\frac{2}{5}[/tex]
Required:
The fraction of the fence the student completes per hour;
Solution;
The time [tex]\mathbf{\frac{2}{5}}[/tex] of the fence is completed = [tex]\frac{3}{4}[/tex] of an hour
Therefore;
[tex]The \ in \ \mathbf{\frac{\dfrac{3}{4} \ hour}{\dfrac{3}{4} \ hour}} = 1 \ hour \ the \ frraction \ completed = \dfrac{\dfrac{2}{5} }{\dfrac{3}{4} \ hour} = \dfrac{8}{15} \ per \ hour[/tex]
The fraction of the fence completed per hour = [tex]\underline{\frac{8}{15}}[/tex]

can someone please help me
Step-by-step explanation:
A. First, convert 30 minutes to a hour.
[tex] \frac{30 \: mins}{1} \times \frac{1 \: hour}{60 \: mins} = 0.5 \: hours[/tex]
[tex]4 + 0.5 = 4.5 \: hours[/tex]
Now, we can subsitue.
Part A: 1.
[tex]d(t) = 6 + 5.5 \cos( \frac{\pi}{6}(4.5) ) [/tex]
[tex]d(t) = 6 + 5.5 \cos( \frac{3\pi}{4} ) [/tex]
Part B:

so
[tex]6 + 5.5( - \frac{ \sqrt{2} }{2} )[/tex]

Create a different equation with distributive property and show the work to solve it.
Answer:
-10(2x + 1/5)
~
1/2(x -4)
Step-by-step explanation:
-10(2x + 1/5)
Distribute -10 to all terms within the parenthesis by multiplying:
-10 * 2x = -20x
-10 * 1/5 = -10/5 = -2
-20x - 2 is your answer.
~
1/2(x -4)
Divide 2 to all terms within the parenthesis:
(x - 4)/2 = (x/2) - (4/2) = (x/2) - 2
[tex]\frac{x}{4} -2[/tex] is your answer.

Answer:
Here's an equation 9 (x+2)
Here's the answer to that equation 9x+18
Step-by-step explanation:
You basically multiply 9 times (x+2) but since you don't know what x is you multiply 9 to each number (or variable) individually. So 9(x) + 9(2). The resulting equation is 9x + 18
[tex]9(x+2)[/tex]
[tex]9(x)+9(2)[/tex]
[tex]9x + 18[/tex]

the highlighted question is wrong haha please i need this by 9
x = 5, AB = 14, BC = 8
=====================================================
Explanation:
The triangles are similar, which can be proven through the angle angle theorem.
The similar triangles allow us to form the proportion below.
EB/DB = AB/BC
7/4 = (2x+4)/(x+3)
7(x+3) = 4(2x+4)
7x+21 = 8x+16
21-16 = 8x-7x
5 = x
x = 5 is part of the answer
Then we can use that x value to find the following
AB = 2x+4 = 2*5+4 = 14 is the length of AB
BC = x+3 = 5+3 = 8 is the length of BC

divide 100cm in the ratio1/2:1/4:1/5 to the nearest whole number
Step-by-step explanation:
step 1: add the ratios
1/2 + 1/4 + 1/5 = 0.95
step 2: divide each ratio by the total sum of the ratios and multiply by a 100
(1/2 ÷ 0.95) × 100 = 52.63 rounded off equals to 53
(1/4 ÷ 0.95) × 100 = 26.31 rounded off equals to 26
(1/5 ÷ 0.95) × 100 = 21.05 rounded off equals to 21
These ratios should add up to a 100
so the ratio are 53 : 26 : 21

A business owner purchases supplies for a laundromat and a car wash.
Part A
The owner purchases 6 cases of laundry soap, 8 cases of fabric softener, and 3 cases of bleach for the laundromat. Each case of laundry soap costs $68.45, each case of fabric softener costs $39.71, and each case of bleach costs $52.25.
Which is the best estimate of the total cost, in dollars, of the laundry items?
A. 750.00
B. 830.00
C. 890.00
D. 920.00
Part B
The owner purchases 5 buckets, 10 brushes, 48 towels, and 1 case of air fresheners for the car wash. The total cost of the purchases is $144.08. Each bucket costs $2.89, each brush costs $7.91, and each towel costs $0.36.
What is the cost, in dollars, of the case of air fresheners?
Enter your answer in the box.
Answer:
part a: is c
part b: $33.25
Step-by-step explanation:
PART A: I did 6x68.45=410.70
8x39.71=317.68
3x52.25=156.75
410.7+317.68+156.75=885.13
so the closest thing to it is c
PART B: i did
5x2.89=14.45
10x9.91=79.10
48x0.36=17.28
14.45+79.10+17.28=110.83
144.08-110.83=33.25
so the case of air fresheners was $33.25

Solve for x. round to nearest tenth or degree, if necessary 19 32
find the value of x please
Answer:
x=21°
Step-by-step explanation:
in the isosceles triangle, if two sides are equal,then the angles opposite those sides are equal.
so, 2x=42° ( exterior angle of a triangle is equal to the sum of the two opposite interior angles)
x=21°
I have no idea how to round to the nearest cent
What is -2x=-8-2y in slope intercept form
Answer: y = x - 4
Step-by-step explanation:
Slope intercept form is y = mx + b
Given:
-2x = -8 -2x
Add 2x and 2y to both sides of the equation:
2y = 2x - 8
Divide both sides of the equation by 2:
y = x - 4
