Garret makes a ramp for his skateboard in the shape of a right triangle with a hypotenuse of 2 ft, and a leg of 1 ft. He wants t

Answer:

5 days

Step-by-step explanation:

(3 1/3 miles)/(2/3 miles/day) = (10/3)/(2/3) days = 10/2 days = 5 days

_____

time = distance / speed

Answer:

Step-by-step explanation:

You take the cube root of each piece of the term separately:

7 x 7 x 7 = 343, so the cube root of 343 = 7

a^3 = a x a x a, so the cube root of a^3 = a

b^6 = b x b x b x b x b x b = b^2 x b^2 x b^2, so the cube root of b^6 = b^2

Answer:

Step-by-step explanation:

You know that:

- 2/5 of the spice mixture was oregano.

- 1/3 of the spice mixture was basil.

Then, to find the fraction of the total amount of spice mixture that was oregano and basil, you must add both fractions, as following:

- Find the least common multiply of the denominators:

- Divide the LCM by each original denominator and multiply the result by each numerator.

- Make the addition.

Then, the result is:

Answer:

1.474

Step-by-step explanation:

Given that :

Population standard deviation, σ = 4

Sample size = 7

Confidence level = 99%

Since we ore using the population standard deviation, the we use the Z distribution table:

The margin of error :

Zcritical * σ/√n

Zcritical at 99% = 2.58

The margin of error :

2.58 * 4/√7

2.58 * 0.5714285

= 1.474

Answer:

0.38 is ten times as much as 0.038
