Answer:
12√2.
Step-by-step explanation:
You can do this by the Pythagoras theorem:
20^2 = x^2 + (4sqrt7)^2 where x is the distance required.
x^2 = 20^2 - (4sqrt7)^2
= 400 - 112
= 288
x = √288
= √144 *√2
= 12√2.
Answer:
30
Step-by-step explanation:
Simplifying
n + -13 = 17
Reorder the terms:
-13 + n = 17
Solving
-13 + n = 17
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '13' to each side of the equation.
-13 + 13 + n = 17 + 13
Combine like terms: -13 + 13 = 0
0 + n = 17 + 13
n = 17 + 13
Combine like terms: 17 + 13 = 30
n = 30
Simplifying
n = 30
1000 minus 250 equals 750.00 now 750 divided 50.00 answers is 15 weeks. In 15 weeks she will have 1000 saved.
