Answer:
Answer
Find out the how many minutes are spent preparing.
To proof
As given
A recipe takes 90 minutes to make.
25 percent of the time is spent preparing the ingredients.
25% is written in the decimal form
= 0.25
Time spent in preparing = 0.25 × 90
= 22.5 minutes
Therefore the 22.5 minutes are spent preparing the ingredients.
Hence proved

Answer:
f(4)=5
Step-by-step explanation:
f(x)=x^2-6x+13
f(4)=4^2-6(4)+13
f(4)=16-24+13
f(4)=5
Answer: F
Explanation: you already know you have a 90° and the straight lines means it’s 180° so you need to find x and z which are the same so 2x + 90=180 which you would then subtract 90 from 180 which would be 90 then divide 90 by two which would be 45
The question is incomplete, the complete question is;
If in 0.5 min the tank gets 0.8 gallons of the water then
how many gallons will be in 1 min ?
how many gallons will be in 3 min?
and how long it takes for 40 gallons?
Answer:
1.6 gallons
4.8 gallons
25 mins
Step-by-step explanation:
This question has to do with proportion.
If it takes 0.5 mins for the tank to get 0.8 gallons
in 1 minute the tank will get 0.8 * 1/0.5 = 1.6 gallons
In 3 minutes the tank will get 3 * 1.6 gallons = 4.8 gallons
if it takes 1 min to get 1.6 gallons
it will take x mins to get 40 gallons
x = 1 * 40/1.6 = 25 mins
You can add up all the equal terms:
So for x: 6x-4x = 2x
For y: 2y
For the numbers: 3+7=10
