let base be x

height = 3x

area = 1/2 * base* height

area = 1/2 * x*3x

Area = 3x^2/2= 27

3x^2= 54


x^2= 54/3

x^2= 18

x= sqrt 18

x= sqrt (3*3*2)

x= 3sqrt2 the base

height = 3 * 3sqrt2

height = 9 sqrt2

Hope this helps!

Try using A=1/2bh
50 is the height in this but the base is confusing me, unless its 97 yards too, unlikely.

Please help me with this question
Olegator [25]

Answer:

x = 11

Step-by-step explanation:

Since we are given triangle PQR is similar to triangle PTU, we can write a proportion to connect the side lengths:

PQ / PT = QR / TU = PR / PU

We don't really care about QR and TU because the are irrelevant to the problem, so we can remove them:

PQ / PT = PR / PU

Now, we can substitute the values given by the diagram:

70 / 30 = 49 / (x + 10)

We can cross multiply,

70(x + 10) = 30 * 49

And divide by 70 on both sides(too lazy to multiply :P)

x + 10 = 3 * 7

x + 10 = 21

x = 11

Estimate the quotients 1.64÷22
Nadya [2.5K]

ANSWER

0.1

EXPLANATION

We want to estimate the quotient of 1.64 ÷ 22.

To do this, we will approximate the two numbers to whole number and solve it.

It becomes:

2 ÷ 20

That is:

Note: since 2 cannot be divided by 20, we write 0. and add a 0 to the back of 2.

The estimate of the quotient is 0.1.
