45! remember multiple is what you multiply the number by, a factor is what you have to multiply to get the number
Answer:
95.7
Step-by-step explanation:
\sin C = \frac{\text{opposite}}{\text{hypotenuse}}=\frac{95}{x}
sinC=
hypotenuse
opposite
=
x
95
\sin 83=\frac{95}{x}
sin83=
x
95
x\sin 83=95
xsin83=95
Cross multiply.
\frac{x\sin 83}{\sin 83}=\frac{95}{\sin 83}
sin83
xsin83
=
sin83
95
Divide each side by sin 83.
x=\frac{95}{\sin 83}=95.7134\approx 95.7\text{ feet}
x=
sin83
95
=95.7134≈95.7 feet
Type into calculator and roundto the nearest tenth of a foot.
The number of standard version download and high-quality download is 870 and 490 respectively.
<h3>Number of downloads of the high-quality version</h3>
let
- Number of high-quality download = y
- Number of standard version = x
x + y = 1360
2.9x + 4.1y = 4532
From (1)
x = 1360 - y
Substitute x = 1360 - y into (2)
2.9x + 4.1y = 4532
2.9(1360 - y) + 4.1y = 4532
3944 - 2.9y + 4.1y = 4532
- 2.9y + 4.1y = 4532 - 3944
1.2y = 588
y = 588/1.2
y = 490
Substitute y = 490 into (1)
x + y = 1360
x + 490 = 1360
x = 1360 - 490
x = 870
So therefore, number of standard version download and high-quality download is 870 and 490 respectively.

Answer:
true
Step-by-step explanation:
Answer:
80 Students were surveyed.
Step-by-step explanation:
To find the answer we need to do a Rule of Three. The Rule of Three is a Mathematical Rule that will help us to solve problems based on proportions.
1. I know that a 65% of students are 52 students. I need to know how many students represent that 100%.
2. So if 52 students mean _____ 65%
X students mean _____ 100%
Pay attention here. We have to put the same elements in the same columns. Students with studients and percentage with percentage.
3. Now I have to cross these details. I have to multiple 52*100. So:
52*100= 5200
4. Then divide that result by 65.
5200/65= 80
5. So 80 is the total number of students surveyed.
