Question:
How long did Jenny read?
The Process:
Step-1: We need to calculate the time of texting a friend in minutes.
Recall that
We crossed out 5 and 60, i.e.,
Therefore,
Step-2: Let us calculate the remaining time.
Step-3: Jenny spends of the remaining time brushing herteeth and putting on her pajamas.
We crossed out 8 and 24, i.e.,
Step-4: Let us calculate how long Jenny read for the rest of time.
Thus, Jenny spent 15 minutes reading a book before its bedtime.

Quick Steps:
Let us calculate how long Jenny read for the rest of time.
Keywords: Jenny, has an hour, before its bedtime, spends 3/5 of an hour, texting a friend, 3/8 of the remaining time, brushing her teeth, putting on her pajamas, reading her book
If the width of the deck is 3 m less that the length. The length is 8m. then the area to be waterproofed is 40 m²
A rectangle is a quadrilateral with four right angles
The area of Rectangle is length times of width.
Given that Ms. Luna is waterproofing the top of a rectangular wood deck.
The width of the deck is 3 m less that the length.
Width=Length-3
Length=8
Area of rectangle=Length×Width
=Length×(Length-3)
=8×(8-3)
=8×5
=40 m²
Hence, If the width of the deck is 3 m less that the length. The length is 8m. then the area to be waterproofed is 40 m²

Answer:
40 m
Step-by-step explanation:
First we have to find the width. the width is 3 less than the length, which is 8... so the width is 5. Area is found by multiplyign length times width to get 40 m.
from 8x^2+10x-10
Answer:
-6x^2 - 7x +1
Step-by-step explanation:
2x^2+3x-9 -(8x^2+10x-10)
3x^2+3x-9 -8x^2-10x+10
Combine like terms
-6x^2 - 7x +1

The aquarium holds 80 quarts of water.
We have,
In the United States customary system, there are 4 quarts in 1 gallon.
This conversion factor is a constant ratio that allows us to convert between gallons and quarts.
So, when we have 20 gallons of water, we can multiply it by the conversion factor of 4 quarts/gallon to find out how many quarts it is equivalent to:
20 gallons x 4 quarts/gallon = 80 quarts
Therefore,
The aquarium holds 80 quarts of water.
The conversion factor helps us determine the equivalent amount of one unit to another.
