wariber [46]

Answer:

She used 67/60 of a bag of gravel in one day.

Step-by-step explanation:

We must get a common denominator so we can add the two fractions.

Let's use 60!

1/5 = 12/60

11/12 = 55/60

Now we can add and get 67/60!

She used 67/60 of a bag of gravel in one day.

The height of a triangle is twice the length of its base. The

lions [1.4K]

Answer:

height = 14.2 m , base = 7.1 m

Step-by-step explanation:

let the base be b then height h = 2b

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh

Here A = 50 , then

$\frac{1}{2}$ × b × 2b = 50

b² = 50 ( take square root of both sides )

b = $\sqrt{50}$ ≈ 7.1 ( to the nearest tenth )

Then base = 7.1 m and height = 2 × 7.1 = 14.2 m
