A car that travels 20 miles in LaTeX: \frac{1}{2}1 2 hour at constant speed is traveling at the same speed as a car that travels 30 miles in LaTeX: \frac{3}{4}3 4 hour at a constant speed. Both cars go miles in LaTeX: \frac{1}{4}1 4of an hour (or 15 minutes). Both cars will travel miles in 1 hour.
Answer:
10 miles per 1/4 hour
40 miles per hour
Step-by-step explanation:
Given that:
A car travels 20 miles in 1/2 hour
Miles traveled per hour :
(20 * 2) / 1 = 40 miles per hour
Mile traveled in 1/4 hour :
Distance = speed * time
Distance = 40 mph * 1/4 = 10 miles per 1/4 hour
Car traveling 30 miles in 3/4 hours
(30 * 4) /3 = 120 / 3 = 40 miles per hour
Distance = 40 mph * 1/4 = 10 miles per 1/4 hour
A tank that is filled with water drains at a rate of d216+4d−100 d 2 16 + 4 d − 100 gallons per minute where d is the depth of the tank in feet. Pumping out a tank that is 120 feet deep with this same pump would empty the tank at what rate? 1380 gal/min 1380 gal/min 1280 gal/min 1280 gal/min 900 gal/min 900 gal/min 387.5 gal/min 387.5 gal/min 487.5 gal/min
Given:
Consider the tank that is filled with water drains at a rate of [tex]\dfrac{d^2}{16}+4d-100[/tex] gallons per minute where d is the depth of the tank in feet.
Depth of tank = 120 feet.
To find:
The rate of water drain for that tank.
Solution:
We have, rate of water drain in gallons per minute.
[tex]r=\dfrac{d^2}{16}+4d-100[/tex]
where, d is the depth of the tank in feet.
Put d=120, to get the rate of water drain for the tank.
[tex]r=\dfrac{120^2}{16}+4(120)-100[/tex]
[tex]r=\dfrac{14400}{16}+480-100[/tex]
[tex]r=900+380[/tex]
[tex]r=1280[/tex]
Therefore, the rate of water drain is 1280 gal/min. Hence, the correct option is B.

Triangles DEF and GHI are shown. Which sequence of rotations, reflections, and/or translations would map triangle DEF onto triangle GHI?
Does mapping triangle DEF onto triangle GHI prove the two triangles are congruent? Explain your reasoning.
Answer:
Part A:
The sequence of transformation that maps triangle DEF to triangle GHI are;
1) A reflection across the y-axis (x, y) →(-x, y) and
2) A translation 6 units down, (-x, y - 6)
Part B:
1) Yes
2) The points of the triangle GHI obtained from the mapping of triangle DEF using the given transformation are corresponding therefore, the mapping proves that the two triangles are congruent
Step-by-step explanation:
Part A:
The given coordinates of the vertices of triangle DEF are;
F(-1, 5), D(-5, 2), and E(-3, 1)
The given coordinates of the vertices of triangle IHG are;
I(1, -1), H(3, -5), and G(5, -4)
Therefore, the transformation that maps ΔDEF to ΔGHI are
1) A reflection across the y-axis (x, y) →(-x, y) and
2) A translation 6 units down, (-x, y - 6)
Reflection of point F(-1, 5) across the y-axis gives → (1, 5)
Followed by a translation 6 units down gives;
(1, 5) →T(y - 6) → I(1, -1)
Reflection of point D(-5, 2) across the y-axis gives → (5, 2)
Followed by a translation 6 units down gives;
(5, 2) →T(y - 6) → G(5, -4)
Reflection of point E(-3, 1) across the y-axis gives → (3, 1)
Followed by a translation 6 units down gives;
(3, 1) →T(y - 6) → H(3, -5)
Part B:
1) Yes mapping triangle DEF onto triangle GHI proves that the two triangles are congruent
2) The points of the triangle GHI obtained from the mapping of triangle DEF are the same, therefore, the mapping proves that the two triangles are congruent

In 25 minutes Jezebel can run 10 laps around the track. Part I) Determine the unit rate for the number of laps she can run per minute. Part II) Find the constant of proportionality for this situation.
Answer: See explanation
Step-by-step explanation:
a. Determine the unit rate for the number of laps she can run per minute.
This will be calculated as the number of minutes used divided by the number of laps which will be:
= 25 / 10
= 2.5 minutes per lap.
b. Find the constant of proportionality for this situation.
We will use the formula y = kx
where y = 25, x = 10, k = constant of proportionality.
Therefore, y = kx
25 = 10k
k = 25/10
k = 2.5
The constant of proportionality is 2.5
Use elimination to solve the system of equations given by 3x+ 4y= 5 and 21x+ 28y= 35.

1/5x + 24 = 50
what does x equal?
Answer:
130
Step-by-step explanation:
1/5x=50-24 subtract 24 to both sides
1/5x=26 multiply 5 on both sides
x=130 multiply 5 to both sides
write an equation of a line parallel to x=3
Answer: y = 4
Step-by-step explanation:
The equation y = 3 represents a vertical line. Thus, any equation in which y = m = 0 would be parallel to this line. Pick a random b-value and plug it into the equation with a slope of 0 and you should have a parallel line equation.

Mia and Evette played a game in which they scored 10 points for each correct answer and lost 20 points for an incorrect answer. Mia answered 7 questions correctly and 3 questions incorrectly. What was Mia's overall score? *
We are told that:
Correct points = 10 per answer
Incorrect points = 20 per answer
Mia answered 7 questions correctly and 3 questions incorrectly.
Hence:
7 (10) + 3(20)
= 70 points - 60 points
= 10 points
Mia's score is 10

Answer:
Answer A is Linear. You can see this because each term is equal to the previous term plus a fixed amount (3), making it an arithmetic sequence.
Answer B is not linear. This is because each term is a multiple of the previous one, making it a geometric sequence.
Answer:
Function A
Step-by-step explanation:
Each time x increases by 1, y increases by 3. Function B is exponential instead of linear, because y increases by a larger number each time rather than increasing by the same amount.

Emmy goes through a 50-ounce jug of laundry detergent in 40 loads. At the store, she
bought a jumbo jug of detergent. The jumbo jug contains 150 ounces of detergent.
How many loads of laundry can Emmy do with the jumbo jug of laundry detergent?
Hence 120 loads of laundry is required with jumbo jug of laundry detergent.
What is laundry detergent?A sort of detergent (cleaning agent) used to clean soiled laundry is laundry detergent (clothes). There are two types of laundry detergent produced: powder (washing powder) and liquid. Builders (about 50% by weight), surfactants (15%), bleach (7%), enzymes (2%), soil deposition inhibitors, foam regulators, corrosion inhibitors, optical brighteners, color transfer inhibitors, perfumes, dyes, fillers, and formulation aids may all be present in laundry detergents.
∵ Number of jumbo jug = 150 /50
n = 3
∴ Laundry loads required of detergent:
= 40 * n
= 40 * 3
= 120 loads
