Raymond developed an app for smartphones. During the first week, he had 7,040 downloads from girls and 3 times as many downloads

myrzilka [38]

Answer:

<u>The correct calculation is D. 7,040 × 3, then 21,120 ÷ 8 </u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of downloads from girls = 7,040

Number of downloads from boys = 3 times as many

Number of boys who downloaded and paid the full version = 1 out of 8

2. Which calculation yields the number of boys who bought the full version of the app?

Number of downloads from boys = 3 * 7,040

Number of downloads from boys = 21,120

Number of boys who downloaded and paid the full version = 21,120/8 = 2,640

<u>The correct calculation is D. 7,040 × 3, then 21,120 ÷ 8 </u>

In a certain town there were 147 robberies last year. This year the number of robberies has gone down 31%. How many robberies we

NNADVOKAT [17]

Answer:

≈101

Step-by-step explanation:

Let x and y represent the number of robberies in last year and this year respectively.

Given;

x = 147

This year the number of robberies has gone down 31%.

So;

y = x - 31% of x

y = x - 0.31x

y = 0.69x

Substituting the value;

y = 0.69 × 147

y = 101.43

y ≈ 101. (to the nearest whole number)

The number of robberies this year = 101

Choose the equation you would use to find the altitude of the airplane. tan70 = 800/x sin70 = x/800 tan70 = x/800

nasty-shy [4]

Answer: tan(70)=x/800

Step-by-step explanation:

Since we are looking at the altitude and x and 800 are given, we will need tangent. Tangent is opposite/adjacent. We can eliminate sin(70). BEtween our 2 tangent choices, the answer is tan(70)=x/800. Tan(70)=800/x is very close but incorrect. 800/x is adjacent/opposite. That is not a trigonometric function.
