A Web music store offers two versions of a popular song. The size of the standard version is 2.4 megabytes (MB). The size of the high-quality version is 4.8 MB
Yesterday, there were 610 downloads of the song, for a total download size of 2400 MB. How many downloads of the high-quality version were there?
10

Answers

Answer 1

Answer:

390

Step-by-step explanation:

We can set up the question as a system of equations:

\(x=\) Standard Version

\(y=\\\) High-quality Version

System of equations:

\(2.4x+4.8y=2400\\x+y=610\)

Now, we solve for y:

\(2.4x+4.8y=2400-- > x+2y=1000\\x+2y=1000\\x+y=610\\\fbox{y=390}\)

She gives a watermelon slice to each kid at the reunion. She also gives a slice to 25 adults.
Gabby hands out 55 watermelon slices in all.
Which equation can you use to find how many kids k are at the reunion?
k - 25 = 55
k

= 55
k + 25 = 55
25k = 55
Solve this equation for k to find how many kids are at the reunion.

Answers

The  equation which can be used  to find how many kids k are at the reunion is :k + 25 = 55

There are 30 kids at the reunion

What is algebraic expression?

Algebraic expressions are based on expressing numbers using letters  without indicating their actual values, such that we can determine the unknown variables by solving the expression or equation.

The total number of watermelons in this case is 55, if 25 slices are handed to the adults in the reunion gathering, the remaining one is the difference between 55 and 25 already served, which is known as k in this case.

total number of watermelons=55

number of adults=25

(1) y - 11 = 4
(2) y = 2x + 3

Answers

Answer:

y = 15 , x = 6

Step-by-step explanation:

you can easily find y from first equation

Move y to the other side of the equation and reverse its sign

so (-11) changes to (+11) and now we have this equation

y = 15

now you must replace 15 instead of y in second equation ,then we have this equation

15 = 2x + 3

now we have to find x

move (+3) to other side of equation and reverse its sign

(+3) changes to (-3)

we have this equation now

15 - 3 = 2x

12 = 2x

x = 12 ÷ 2 = 6

Answers

The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.

The correct answer is 4.

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.

Given information:

- Circle C (cats): 15

- Circle D (dogs): 21

- Circle F (fish): 12

- Overlap of C and F: 2

- Overlap of F and D: 0

- Overlap of D and C: 3

- Overlap of all 3 circles: 1

- Number outside of circles: 14

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.

From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.

To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.

Therefore, from the options given correct one is 4.

460 square feet
640 square feet
960 square feet
1,280 square feet

Answers

The area οf the actual bridge deck in square feet is 1,280 square feet.

What is Area?

Area refers tο the measurement οf the size οf a twο-dimensiοnal surface, usually measured in square units such as square inches, square feet, οr square meters. It represents the amοunt οf space that is inside the bοundary οf a flat οbject οr shape.

The scale οf the drawing is 40:1, which means that the dimensiοns οf the scaled bridge deck are 40 times smaller than the actual bridge deck. Tο find the area οf the actual bridge deck in square feet, we need tο cοnvert the dimensiοns οf the scaled bridge deck frοm inches tο feet and then multiply by the square οf the scale factοr (40² = 1600).

The dimensiοns οf the scaled bridge deck in feet are:

24 inches = 2 feet

4 and 4/5 inches = 0.4 feet

Sο, the area οf the scaled bridge deck in square feet is:

2 feet x 0.4 feet = 0.8 square feet

Tο find the area οf the actual bridge deck in square feet, we need tο multiply the area οf the scaled bridge deck by the square οf the scale factοr:

Area οf actual bridge deck = 0.8 square feet x (40²) = 1280 square feet

A boat heading out to sea starts out at Point A, at a horizontal distance of 1357 feet
from a lighthouse/the shore. From that point, the boat's crew measures the angle of
elevation to the lighthouse's beacon-light from that point to be 9°. At some later time
the crew measures the angle of elevation from point B to be 3°. Find the distance
from point A to point B. Round your answer to the nearest tenth of a foot if
necessary.

Answers

The distance from point A to point B is 2744.1 feet.

Define Trigonometric ratio

The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).

Given, horizontal distance = 1357 feet

Let h  = height of the lighthouse

tan(A) = perpendicular / base

where, perpendicular = h

base = 1357 feet

Angle is 9°

so now, put these value in trigonometric ratio

tan(9) = h / 1357

where, tan(9) = 0.1584

h = 1357 * 0.1584

h = 214.9 feet

Let d = distance from point B to the Lighthouse base

Angle is 3°

h = 214.9 feet

so, tan(3) = 214.9 / d

where, tan(3) = 0.0524

0.0524 = 214.9 / d

d = 214.9 / 0.0524

d = 4101.1 feet

Distance between point A to B = 4101.1 - 1357

                                                    = 2744.1 feet

Therefore, the distance from point A to point B is 2744.1 feet

number of calories per day that should come from simple sugars?

(Simplify your answer. Type an integer or a decimal)

Answers

Answer:

The maximum number of calories per day that should come from simple sugars is 845.

Step-by-step explanation:

Given:

Physically active adult weighing 170 pounds needs to consume about 2815 calories per day to maintain weight.

A nutritionist recommends that no more than 30% of those calories should come from simple sugars.

To find the maximum number of calories per day that should come from simple sugars:

Step 1: Calculate the total number of calories that can come from simple sugars.

Since the maximum percentage of calories that should come from simple sugars is 30%, we can calculate the maximum number of calories from simple sugars as:

Maximum calories from simple sugars = 0.3 x 2815 calories

Maximum calories from simple sugars = 844.5 calories

Step 2: Round the result to the nearest whole number or leave it as a decimal.

Rounding the result to the nearest whole number gives:

Maximum calories from simple sugars = 845 calories

Therefore, the maximum number of calories per day that should come from simple sugars is 845.


Which of the following statements is true about the graphs of f(x)=x and g(x) = f(x+2)?
a. g(x) is the graph of f(x) translated 2 units to the right.
b. g(x) and f(x) have the same y-intercept.
C. g(x) is the graph of f(x) translated 2 units down.
d. g(x) is the graph of f(x) translated 2 units to the left.

Answers

The correct statement is

Option (a) g(x) is the graph of f(x) translated 2 units to the right.

Rules of Translation of a Graph:

The general rule for translating a graph is as follows:

To translate the graph of y = f(x) horizontally by h units, we replace x with (x - h) in the equation of the function.

This implies the graph moving h units to the right if h is positive, or to the left if h is negative.

To translate the graph of y = f(x) vertically by k units, we add k to the equation of the function, resulting in y = f(x) + k.

This implies the graph is moving k units up if k is positive, or down if k is negative.

Here  we have

The graphs of f(x) = x and g(x) = f(x+2)

=> g(x) = x + 2

We observe that the graph g(x) is formed by adding 2 units to the x coordinate of f(x)

Therefore,

The correct statement is

Option (a) g(x) is the graph of f(x) translated 2 units to the right.

There are 10 students with their own cell phone

1/2  of the 10 can use social media

5 have their own cell phone and can use social media

Answer: 10 students have a cell phone and only 5 of them can use social media

Step-by-step explanation: We see there are 40 students in total and 1/4 OF the class have their own cell phone. The OF means multiplacation so we do 40 X 1/4 which is 10 students who have their cellphone. We then again see 1/2 OF the 10 students can use social media meaning we do 10 X 1/2 which is equal to 5 students out of the 10 can use social media.
