Answer:
a. 12 minutes
b. 34 minutes
Step-by-step explanation:
Here, we are told that Ima has driven 5 minutes before Polly started driving
So if Ima has driven for x minutes , polly would have driven for y minutes but the difference between x and y is 5
So mathematically;
x = y + 5
a. 17 = y + 5
y = 17-5 = 12 minutes
b. x = 29 + 5
x = 34 minutes
Answer: x ≤ 3
Step-by-step explanation:
4x ≤ 12
divide each side by 4
x≤3
1. 2.6 x 10^-2, 6.2 x 10^-1, 3.5 x 10^2, 1.5 x 10^4
2.6 x 10^-2, 6.2 x 10^-1, 3.5 x 10^2, 1.5 x 10^4
2.6 x 10^-2, 6.2 x 10^-1, 3.5 x 10^2, 1.5 x 10^4
2.6 x 10^-2, 6.2 x 10^-1, 3.5 x 10^2, 10^4, 1.5 x 10^4
2. 6^5
3. 9^9
A pool that is 5/10 full has less water.
5/10 = 50%
9/10 = 90%
Answer:
10% Decrease
Step-by-step explanation:
Let the number is 100.
Now, if we increase the number by 20%, the new number will be -
100 + (100 × 20%) = 100 + 20 = 120
The new number is 120.
Again, if we decrease the new number by 25%, the number will be -
120 - (120 × 25%) = 120 - 30 = 90
The new number is 90.
The change will be decreased by = (100 - 90) = 10
Percentage change = (10 ÷ 100) × 100 = 10%
