Andre has seven dollars he needs $50 to buy a skateboard each week his grandmother pays him four dollars to complete some chores how much money does Andre have after the week
Answer:
$11
$39
Step-by-step explanation:
Amount Andre has = $7
Amount his grandmother pays him every week = $4
Amount Andre needs to buy a skateboard = $50
how much money does Andre have after the week?
Amount of money Andre has after the week = Amount Andre has + Amount his grandmother pays him every week
= $7 + $4
= $11
Amount of money Andre has after the week = $11
Amount Andre needs more to buy the skateboard = Cost of the skateboard - Amount of money Andre has after the week
= $50 - $11
= $39
Amount Andre needs more to buy the skateboard = $39

Find the volume and show work
Answer:
Volume = 2512 km³
Volume = 800π km³
Step-by-step explanation:
Volume Cylinder = Area circle * height
Let's input the info
Formula for the Area of a circle = πr²
Area circle = π*100
Since it asks to leave in terms of π or tenths ill give both.
Area circle = 100π
Area circle = 314
Volume = 100π * 8
Volume = 800π
Volume = 314 * 8
Volume = 2512
Units = km³
Volume = 800π km³
Volume = 2512 km³

Katelyn invested $1500 into her account which earned interest compounded continuously. After 10 years, she discovered that she had $3935.36. What interest rate percent did Katelyn earn?
Answer: ____ % interest
Given:
Principal = $1500
Time = 10 year
Amount after interest compounded continuously = $3935.36
To find:
The rate of interest.
Solution:
The formula for amount after continuous compound interest is:
[tex]A=Pe^{rt}[/tex]
Where, P is principal, r is the rate of interest in decimal and t is time in years.
Putting [tex]P=1500,A=3935.36,t=10[/tex] in the above formula, we get
[tex]3935.36=1500e^{r(10)}[/tex]
[tex]\dfrac{3935.36}{1500}=e^{10r}[/tex]
[tex]2.6236=e^{10r}[/tex]
Taking ln on both sides, we get
[tex]\ln(2.6236)=\ln e^{10r}[/tex]
[tex]0.9645=10r[/tex] [tex][\because \ln e^x=x][/tex]
Divide both sides by 10.
[tex]\dfrac{0.9645}{10}=r[/tex]
[tex]0.09645=r[/tex]
The rate of interest in percentage is:
[tex]r=100\times 0.09645[/tex]
[tex]r=9.645\%[/tex]
Therefore, the required rate of interest is 9.645%.

Marulla's z score on a college entrance exam is 1.3. If the raw scores have a mean of 480 and a standard deviation of 70 points, what is her raw score?
Answer:
571
Step-by-step explanation:
We solve using z score.
z = (x-μ)/σ, where
x is the raw score = ?
μ is the population mean = 480
σ is the population standard deviation = 70
z = 1.3
Hence,
= 1.3 = x - 480/70
Cross Mulitiply
1.3 × 70 = x - 480
91 = x - 480
x = 480 + 91
x = 571
Therefore, Marulla's raw score is 571

In a game, students draw a card, replace it, and then draw again. What is the probability of drawing a prime number then a composite number
Answer:
16 / 81
Step-by-step explanation:
Between digits 0 ,1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9
Prob (prime number) = Prime numbers / Total numbers ; Prime numbers = 1,3,5,7. So, Prob = 4 / 9
Prob (composite number) = Composite numbers / Total numbers ; Composite numbers = 2, 4, 6 , 8. So, Prob = 4 / 9
Prob (Prime & Composite) = 4 / 9 x 4 / 9 = 16 / 81

Step-by-step explanation:
Plz give me brainliest
Number of miles a car travels are 28.
What is division?The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.
Number of gallons of gas = 20
A car with 20 gallons of gas can drive 560 miles
Based on the given conditions,
= [tex]\frac{560}{20}[/tex]
= 28
Hence, number of miles are 28.

The graph of a function contains the points (6, 7) and (10, 13). Which of these statements is correct based on this information?
A. If the graph also contains the point (4, 4) then the function must not be linear.
B. If the graph also contains the point (12, 16) then the function must not be linear.
C. If the graph also contains the point (1, 2) then the function could be linear.
D. If the graph also contains the point (8, 10) then the function could be linear.
Answer:
The true statements are:
B and D.
Step-by-step explanation:
First, a linear function can be written as:
y = a*x + b
Such that a is the slope, and b is the y-intercept.
If we know that the graph of the function passes through the points (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Here we have a function that passes through the points (6, 7) and (10, 13), then if this function is linear, the slope is:
a = (13 - 7)/(10 - 6) = 6/4 = 3/2
Then the function will be something like:
f(x) = (3/2)*x + b
Knowing that the function passes through (6, 7), this means that:
f(6) = 7
Then:
(3/2)*6 + b = 7
3*3 + b = 7
9 + b = 7
b = 7 - 9 = -2
The function, if linear, is:
f(x) = (3/2)*x - 2
Now let's read the statements:
A) If the graph also contains the point (4, 4) then the function must not be linear.
If the point is a solution of the equation, then the function is linear.
If the point is not a solution of the equation, then the function is not linear.
f(4) = 4 = (3/2)*4 - 2
4 = 3*2 - 2
4 = 6 - 2 = 4
Then (4, 4) is a solution, so if the graph also contains the point (4, 4) the function can be linear. Then the statement "A" is false.
Now let's do the same analysis for the other statements:
B) If the graph also contains the point (12, 16) then the function must not be linear.
F(12) = 6 = (3/2)*12 - 2 = 3*6 - 2 = 18 - 2 = 16
6 = 16
(12, 16) is not a solution, so if the graph contains this point, the function is not a linear function, the statement is true.
C) If the graph also contains the point (1, 2) then the function could be linear.
f(1) = 2 = (3/2)*1 - 2 = 3/2 - 2 = -1/2
The point (1, 2) is not a solution, so if the graph contains this point, then the function can't be linear, so the statement is false.
D) If the graph also contains the point (8, 10) then the function could be linear.
f(8) = 10 = (3/2)*8 - 2
10 = 3*4 - 2 = 12 - 2
10 = 10
The point (8, 10) is a solution of the linear equation, so if the graph contains this point, the function could be linear, so the statement is true.

360
The degrees of rotation that will carry the square onto itself are,
⇒ 90°, 180°, 270°, 360°
Since, A Square is a two dimension figure with 4 sides, 4 corners and 4 right angles. All the sides of the square are equal and parallel to each other.
Given here:
A square is rotated clockwise about center point P.
Now , Since there are have 4 vertices, your starting vertex can land in 4 different starting places and still come up with the same figure.
So if you take 360/4 you get 90 degree rotations to each consecutive vertex.
or more specifically;
= 360/4
= 90
Hence, the square will coincide itself after every integral multiple of 90.
Thus, 90°, 180°, 270°, 360° are the required angles of rotation.
