There are between 24 and 40 students in a
class.
The ratio of boys to girls is 4:7
How many students are in the class?
Answers
Answer:
Step-by-step explanation:
The ratio of boys is 4/11
You need a number that is divisible by 11.
11 represents the number of students in the class. That was obtained by adding 4 and 7 together. So there are 4/11 boys and 7/11 girls.
You could try 33 which is between 24 and 40
4/11 * 33 = 12
There are twelve boys in the class.
7/11 * 33 = 21
There are 21 girls in the class.
21 + 12 = 33 which is exactly what you need.

Answer for Blank 1:
Answers
Answer:
54
Step-by-step explanation:
Surface area of triangular prism = bh + L(s1 + s2 + s3)
Where,
b = 3
h = 4
L = 3.5
s1 = 3
s2 = 4
s3 = 5
Plug in the values into the equation
Area of the triangular prism = 3*4 + 3.5(3 + 4 + 5)
= 12 + 42
= 54 units²

Answer:
B, E, F
Step-by-step explanation:
Answer:
B, F
Step-by-step explanation:
A is false; the slope of function Z is 1/4 and the slope of function W is 1/2. 1/2 is greater than 1/4.
B is true. The slope of function Z is less then the slope of function W.
C is false, the y-intercept of function Z is -2 and the y-intercept of function W is -1. They are not the same number.
D is false, the y-intercept of function W is greater than Function Z.
E is false, -3 and -3 are equal
Function W:
y = 1/2x - 1
y = 1/2(-4) - 1
y = -4/2 = -2
y = -2 - 1
y = -3
Function Z:
y = 1/4x - 2
y = 1/4(-4) - 2
y = -1 - 2
y = -3
F is true, if y = -4 for functions W and, they would both be equal.
Chang used a coordinate plane to show where his posters are displayed on his bedroom wall. Three posters are located at E(5, 3), F(–4, 3), and G(–4, 5). Use absolute values of coordinates to find the distances between points E and F, and between points G and F. Enter your answers in the boxes. EF = units GF = units
Answers
Answer:
EF = 9
GF = 2
Step-by-step explanation:
For EF, we want to find the distance between their c coordinates, since their y coordinates are the same. We want the distance between -4 and 5, which when you add their distance from 0, is 9.
For GF, they share the same x coordinate, so you're finding the distance between their y coordinates, which are 3 and 5. The distance between the two is 2, so the length of GF is 2.

A new car is purchased for 18,000 dollars. The value of the car depreciates at 11.5% per year. What will the value of the car be, to the nearest cent, after 10 years?
Answers
Answer:
Step-by-step explanation:
The exponential decay function is
[tex]v(t)=a(b)^t[/tex] where b, the rate of decay, for us is (1 - .115) and a is the original value of the car which, for us, is 18000. t is the time in years. Using this information to write the equation we need to solve for the value when the car is 10 years old:
[tex]v(t)=18000(.885)^t[/tex] and we sub in 10 for t:
[tex]v(t)=18000(.885)^{10[/tex] which simplifies to
v(t) = 18000(.2947356754) so
v(t) = 5305.24

A music website charges x dollars for individual songs and y dollars for entire albums. Person A pays $5.45 to download 2 individual songs and 3 albums. Person B pays $8.41 to download 5 individual songs and 4 albums. Write a system of linear equations that represents this situation. How much does the website charge to download a song? an entire album?
Answers
Answer:
Amount charged for downloading individual songs = x dollars
Amount charged for downloading an entire album = y dollars
In respect to person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
In respect to person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second, we get
4x + 3(12.96 - 3x) = 33.93
4x + 38.88 - 9x = 33.93
- 5x = - 4.95
x = 0.99 dollars
Putting the value of x in the first equation, we get
y = 12.96 - 3x
= 12.96 - 2.97
= 9.99 dollars

John is 8 years younger than Ahmad. If the sum of their ages is 38, how old is John?
Answers
Since John is 8 years younger than Ahmad, the equation would be as follows:
x+x-8=38
Solve for x:
2x-8=38
38+8=46
2x=46
x=23
23 is Ahmad’s age, subtract 8 from this and you’ll get 15 for John’s age.

Put in terms of 4 as denominator
3/4x + 12/4 - 8/4x = -1/4 + 2/4x + 20/4
Combine like terms
-5/4x + 12/4 = 2/4x + 19/4
Simplify
12/4 = 7/4x + 19/4
-7/4 = 7/4x
x = -1 :)
Check:
3/4(-1) + 3 - 2(-1) = -1/4 + 1/2(-1) + 5
-3/4 + 3 + 2 = -1/4 - 1/2 + 5
-3/4 + 5 = -3/4 + 5
-3/4 = -3/4 :)
