Step-by-step explanation:
Louise: Water = 4.6 + 1.2*t gallons of water
Isaac: Water = 54.6 - 0.8 * t t is in minutes.
When will the two amounts of water be equal
When the two waters are the same.
4.6 + 1.2*t = 54.6 - 0.8t Add 0.8t to both sides
4.6 + 1.2*t + 0.8*t = 54.6 Combine the left
4.6 + 2t = 54.6 Subtract 4.6 from both sides.
4.6-4.6 + 2t = 54.6 - 4.6 Combine
2t = 50 Divide by 2
t = 50/2
t = 25
Answer: both aquariums will have the same amount of water in 25 min

A pawn show purchase a DVD player for $12.00 and sold it to a customer for 40% more than the purchase price. The customer was charge 7.5% tax when the DVD player was sold. What was the total, including tax?
Answers
Answer:
$18.06
Step-by-step explanation:
The price the pawn shop charged for the DVD player was 40% more than what it paid, so was ...
$12.00 + $12.00 × 0.40 = $12.00×(1 +0.40) = $16.80
__
The tax on the purchase is this price multiplied by the tax rate:
tax = 0.075×$16.80 = $1.26
__
Then the total including tax is ...
$16.80 +1.26 = $18.06 . . . . . total cost of the DVD player

AABC is similar to ADEF. The measure of AC = 10, the measure of DE=8, the measure of BC = 6, and the measure of DF = 20.
Find the measures of AB and EF.
Answers
The measure of AB and EF for the similar triangle ABC and DEF are 4 and 12 respectively.
What are similar triangles?Similar triangles are triangles that have the same shape, but their sizes may vary.
In similar triangles, corresponding sides are always in the same ratio. The angles are congruent.
ΔABC is similar to ΔDEF. Therefore, the sides will form a ratio.
AC / DF = BC / EF = AB/DE
AC = 10
DF = 20
DE = 8
BC = 6
Hence,
10 / 20 = AB / 8
cross multiply
20AB = 80
AB = 80 / 20
AB = 4
Hence,
10 / 20 = 6 / EF
10EF = 120
EF = 120 / 10
EF = 12

Find the lateral area of a waffle cone with a diameter of 4.6 in. and a slant height of 7.9 in. Give your answer in terms of ℼ .
Answers
Answer:
18.17 × pi in²
Step-by-step explanation:
there are many seemingly different formulas out there for this, but they are actually all the same and differ only by what values of the cone we know at the beginning (and the custodian values are converted into the values we need for the calculation).
do we know the base area and the height of the cone, or the radius and the height, or the base area and the slant height (the length of the "mantle" straight from the bottom to the top), ... ?
well, here we know the diameter (this means it is 2 times the radius) and the slant height.
this is one of the easiest exercises.
the formula for this case is
LA = pi × radius × slant height = pi × (4.6 / 2) × 7.9 =
= pi × 2.3 × 7.9 = 18.17 × pi in²
The figure shows a carpeted room. How many square feet of the room are carpeted?
A polygon that is a part of a rectangle is shown with perpendicular sides. The top is labeled 6 feet. The side on the left is labeled 8 feet. The base is labeled 2 feet, and the side adjacent to it on the right is labeled 3 feet
24 square feet
28 square feet
34 square feet
36 square feet
Answers
Answer:
36 square feet
Step-by-step explanation:
Check the attachment for the missing sides.
1) We calculate the missing sides by subtracting one of the similar sides with the longest one possible. In this case, 6 - 2 = 4 and 8 - 3 = 5.
2) Strikethrough the compound shape, creating two shapes; then, label them. Check the diagram attached.
3) Now, let's find the area of each of the squares; and then, add them.
Shape A:
= 4 × 5
= 20
Shape B:
= 2 × 8
= 16
Total:
= 20 + 16
