An elm tree is 3 and one-half times as tall as an apple tree. The apple tree is 10 and two-thirds feet tall. How tall is the elm

In-s [12.5K]

Answer:

The elm tree is 40 5/6 inches tall

Step-by-step explanation:

Let

Tallness of the apple tree = x

Tallness of the elm tree= 3 1/2x

Apple tree = 10 2/3 feet tall

Elm tree = 3 1/2x

Where x= 10 2/3

Elm = 3 1/2 (10 2/3)

= 7/2(35/3)

= 7*35 / 2*3

= 245 / 6

= 40 5/6 inches tall

The elm tree is 40 5/6 inches tall

Been a while since I’ve needed to not use a calculator. Why is -2X10^-18 (3/16) = 4.09X10^-19?

Anestetic [448]

Answer:

see the explanation

Step-by-step explanation:

we have

$2.18*10^{-18}(\frac{3}{16})$

we have that

$\frac{3}{16}=0.1875$

Convert to scientific notation

$0.1875=1.875*10^{-1}$

substitute

$2.18*10^{-18}(1.875*10^{-1}})$

Remember that

To multiply two numbers in scientific notation, multiply their coefficients and add their exponents

$2.18*10^{-18}1.875*10^{-1}}=(2.18*1.875)*10^{(-18-1)}=4.0875*10^{-19}$

Round the number 4.0875 two decimal places

so

$4.0875*10^{-19}=4.09*10^{-19}$
