Marco puts his coins into stacks. Each stack has 10 coins.
He makes 17 stacks of quarters.
He makes 11 stacks of dimes.
He makes 8 stacks of nickels.
How much money does Marco have in his stacks of coins?
Answer:
Marco has $57.50 in total.
Step-by-step explanation:
17 x 10 = 170 quarters
170 x 0.25 = $42.50
11 x 10 = 110 dimes
110 x 0.10 = $11.00
8 x 10 = 80 nickels
80 x 0.05 = $4.00
S is located at (9 -3) point T is located at (4 -3)
what is the distance from point S to point T
Answer:
5
Step-by-step explanation:
The distance formula is:
[tex]d = \sqrt {\left( {x_2 - x_1} \right)^2 + \left( {y_2 - y_1} \right)^2 }[/tex]
We can plug in the given coordinates into the equation:
[tex]d = \sqrt {\left( {4 - 9} \right)^2 + \left( {-3 - (-3)} \right)^2 }\\d = \sqrt {\left( {-5} \right)^2 + \left( {-3+3} \right)^2 }\\d = \sqrt{25 + \left( {0} \right)^2 }\\d=\sqrt{25+0}\\d=\sqrt{25}\\d=5[/tex]
A car requires 9 liters of gasoline to cover a distance of 108 km. If the car
spent 12.5 liters of gasoline, how far did the car travel?
Answer: 150km
Step-by-step explanation:
The question says that the car required 9 litres of gasoline to cover 108km which means we and then derive that:
9L = 108km
And we are trying to find out how much distance can cover:
12.5L =?
Therefore, in order to find out the distance, we need to figure out how much distance can 1L take the car
therefore:
1L = [tex]\frac{108km}{9L}[/tex] = 12km
So if we know how far 1L can take us, we can just multiply 12.5 litres by the 12km to find out the distance:
12.5L × 12km = 150km
So, therefore, 12.5 litres can cover 150km.

∠ and ∠ are complementary angles. If ∠ = (12x - 3)° and ∠ = (7x - 2)°, find the
∠.
Answer:
57 °
Step-by-step explanation:
Complementary angles = 90 °
Since, Your angle don't have ∠ [ ] Then Let let "C" and "y"
Thurs, C = 12x- 3 and y = 7x - 2
It is given that angles r and s are complementary angles. Two angles are complementary if they add up to 90 degrees. This means the sum of measures of angle r and angle s must be 90 degrees. So,
c + y = 90
12x - 3 + 7x - 2 = 90
19x - 5 = 90
19x = 95
x = 95/19
x = 5
Using the value of x in expression or r, we get:
c = 12x - 3 = 12(5) - 3 = 60 -3 = 57 degrees.
So measure of angle c is 57 degrees.
Hence, the ∠ is 57 °

Luna drew a scale drawing of the high school. The parking lot, which is 54 meters wide in real life, is 102 centimeters wide in the drawing. What scale did Luna use? 17 centimeters:___meters
Scale drawings are used to draw shapes in a different proportional size
The scale used in the drawing is 17 centimeters : 9 meters
How to determine the scale of the drawingFrom the question, we have:
Real length = 54 metersScale length = 102 centimetersSo, the scale is:
Scale = Scale length : Real length
This gives
Scale = 102 centimeters : 54 meters
Reduce the scale
Scale = 17 centimeters : 9 meters
Hence, the scale used in the drawing is 17 centimeters : 9 meters

Answer:
The initial height is the y-intercept of the graph
slope of the graph = -2
Jordon interprets the only the slope correctly.
Aral interprets the only the initial height correctly.
Step-by-step explanation:
Slope = change in y ÷ change in x = (0 - 12) ÷ (6 - 0) = -12 ÷ 6 = -2
So the slope of the graph = -2
by inspection, the y-intercept = 12
Therefore, the equation for the line is y = -2x + 12

A carpenter lays 18 square feet of tiles in 2/3 of an hour. How many square feet of tile does the carpenter lay per hour?
How would I do this problem if the options are the following choices:
A: 12 Square Feet Per Hour
B: 17 1/3 Square Feet Per Hour
C: 18 2/3 Square Feet Per Hour
D: 27 Square Feet Per Hour.
Answer:
D. 27 square feet per hour
Step-by-step explanation:
Step 1:
Find the unit rate. Since 18 tiles are per 2/3 of an hour, we can divide 18 by 2 to get 9 tiles layed per third hour.
Step 2:
Multiply the 9 per third of an hour by 3 to find how many are per hour,
[tex]9*3=27[/tex] square feet per hour

The y-intercept of f(x) is equal to the y-intercept of g(x). The y-intercept of f(x) is equal to 2 times the y-intercept of g(x). The y-intercept of g(x) is equal to 2 times the y-intercept of f(x). The y-intercept of g(x) is equal to 2 plus the y-intercept of f(x).
The y-intercept of g(x) is equal to 2 plus the y-intercept of f(x).

As the two equations are given to us, k(x) and p(x), and we need to find (k ∘ p)(x), And we know the product of two functions can be written as,
[tex](k \cdot p)(x) = k(x) \cdot p(x)[/tex]
