Amy is training for a half marathon. in practice, she runs 2 miles in 15 minutes. If she continues at the same rate, how many miles will she run in 1 hour?
A. 4
B. 8
C. 16
D. 30
Step-by-step explanation:
B. 8
she will run for 8 miles,
stepfind Amy's speed
convert the minutes into hours by dividing by 60
[tex] \frac{2}{15 \times \frac{1}{60} } \\ = 8 \: miles \: per \: hour[/tex]
find the number of miles ran by multiplying the speed by the time, ie
[tex]8 \times 1 = 8 \\ \: therefore \: the \: answer \: is \: \: 8 \: miles[/tex]
Hector took out a small loan of $900 for 18 months. The simple interest rate on the loan was 10.5%. How much will he pay in interest on the loan?
Answer:
The answer would be $1.89 in interest.
Step-by-step explanation:
First, change 10.5% into a decimal. To do this, you divide 10.5÷100. This equals 0.105
next, you multiply 0.105 with 12 (12 months in a year)
This equals 1.26
But, Hector still has 6 months left he has to pay for.
So, one way you can do this is divide 1.26 by 2, which equals 0.63.
THEN, you add 0.63 with 1.26, giving you the answer, 1.89
So, the answer for this equation would be 1.89.

What is the equation of a line parallel to 2x−3y=5 that passes through the point (−9,2)?
3x−2y=−31
3x+2y=−23
2x−3y=−24
2x+3y=−12
Parallel lines have the same slope
The equation of the line is: [tex]\mathbf{y = \frac 23x + 8}[/tex]
From the question, we have:
[tex]\mathbf{2x - 3y = 5}[/tex]
Make y the subject
[tex]\mathbf{- 3y = 5 - 2x}[/tex]
Divide through by -3
[tex]\mathbf{y = \frac 23 x - 5}[/tex]
Because the required equation is parallel to [tex]\mathbf{2x - 3y = 5}[/tex], then they must have the same slope
A linear equation is represented as:
[tex]\mathbf{y=mx + c}[/tex]
Where:
m represents the slope
So, by comparison:
[tex]\mathbf{m = \frac 23}[/tex]
This means that:
The required equation has a slope of 2/3
The equation of the line is:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
Where:
[tex]\mathbf{m = \frac 23}[/tex]
[tex]\mathbf{(x_1,y_1) = (-9,2)}[/tex]
So, we have:
[tex]\mathbf{y = \frac 23(x + 9) + 2}[/tex]
Open brackets
[tex]\mathbf{y = \frac 23x + 6 + 2}[/tex]
[tex]\mathbf{y = \frac 23x + 8}[/tex]
Hence, the equation of the line is: [tex]\mathbf{y = \frac 23x + 8}[/tex]

X= - 3/4Y -5. Please put this in slope intercept.
y = - 4/3 x - 20/3
Step-by-step explanation:
x = - 3/4 y - 5 Move Terms
3/4 y = - 5 - x Divide both sides
y = - 20/3 - 4/3 x Reorder the terms
y = - 4/3 x - 20/3
Hint :- The slope intercept form of the line is [tex] y = mx + c [/tex] , where m is the slope of the line and c is y intercept .
Solution:-
Given equation to us ,
[tex]\implies x = \dfrac{-3}{4}y -5 [/tex]
Multiply both sides by 4 ,
[tex]\implies 4x = -3y -20 [/tex]
Add 20 to both sides ,
[tex]\implies 4x +20 = -3y [/tex]
Divide both the sides by -3 ,
[tex]\implies \dfrac{-4}{3}x-\dfrac{20}{3}= y [/tex]
Flip the equation ,
[tex]\implies y = \dfrac{-4}{3}x-\dfrac{20}{3} [/tex]

Type of Fruit Cost Estimated Cost apple $1.75/pound W 8.75 orange $2.35/pound 9.40 banana $1.50/pound 4.50 Annie bought 5 pounds of apples, 4 pounds of oranges, and three pounds of bananas. Part a. Round the prices to the nearest whole dollar to estimate how much money she spent. Part b. How much money did Annie actually spend? Write a numerical expression to represent the amount of money that Annie spent. Was your estimation an overestimation or underestimation? Why do you think that might be?
Answer:
For part B
Step-by-step explanation:
($1.75*5 pounds of apples)+($2.35*4 pounds of oranges)+($1.50*3 pounds of bananas) = $8.75+$9.40+$4.50 = $22.65
Overestimation
Answer:. the estimate would be 52 dollars
the actual number would be 48.25 dollars
(1.75*5)+(8.75*4)+(1.50*3)=48.25
(2*5)+(9*4)+(2*3)=52
it was an over estimate

A batting machine uses an automatic baseball feeder. During baseball
practice the feeder is a full. An attendant fills it with 15 baseballs so
that the feeder is now full. How many baseballs does the feeder
hold when full?
A. Write an equation to represent the problem.
The feeders in battling machine are represented in proportions and fractions.
The equation that represents the problem is: [tex]\mathbf{\frac 16x + 15 = \frac 23x}[/tex]The feeder can hold 30 baseballs, when fullThe given parameters are:
[tex]\mathbf{Initial = \frac 16x}[/tex] ------ 1/6 full
[tex]\mathbf{Additional = 15}[/tex] --- baseballs added
[tex]\mathbf{Final = \frac 23x}[/tex] ---- 2/3 full
So, the equation that represents the problem is:
[tex]\mathbf{Initial + Additional = Final}[/tex]
So, we have:
[tex]\mathbf{\frac 16x + 15 = \frac 23x}[/tex]
The number of baseballs it can hold is calculated as follows:
[tex]\mathbf{\frac 16x + 15 = \frac 23x}[/tex]
Multiply through by 6
[tex]\mathbf{x + 90 = 4x}[/tex]
Collect like terms
[tex]\mathbf{4x - x = 90 }[/tex]
[tex]\mathbf{3x = 90 }[/tex]
Divide through by 3
[tex]\mathbf{x = 30 }[/tex]
Hence, the feeder can hold 30 baseballs, when full

The equation of the line is represented in table number 2. Then the correct option is B.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
From the graph, the y-intercept is 5. Then the equation is given as,
y = mx + 5
From the graph, the equation passes through (-4, -3). Then we have
- 3 = (-4)m + 5
- 8 = - 4m
m = 2
Then the equation is given as,
y = 2x + 5
The equation of the line is represented in table number 2. Then the correct option is B.
