Simplify the square root
7 \sqrt{90}  =  7\sqrt{3 { }^{2}  \times 10}
Separate the numbers in the square root to look like this
7 \sqrt{3 ^{2} }  \sqrt{10}
Because three is squared, it cancels out the square root
7 \times 3 \sqrt{10}
Simplify to get your answer:
21 \sqrt{10}

Evaluate the following expression for y = - 2.<br> - 3<br> y
bekas [8.4K]

Answer:

-1/8

The given expression is y⁻³

We want to find the value of the expression when y = -2

Thus;

At y = -2, we have; -2⁻³

According to law of exponents, x⁻⁴ = 1/x⁴

How many pieces of wire 2½ cm long, can be cut from a roll of wire 58 cm long?<br>No links please.​
tatuchka [14]

Step-by-step explanation:

Break it into steps you can better understand

2 1/2 = 2.50cm

You want to take as many 2.50 cm pieces as possible so you cut one off.

58 - 2.50 = 55.5

and another

55.5-2.50 = 53

and so on...

Instead of subtracting like this, we use division

58 / 2.5

when you divide, this tells you how many 2.50cm pieces you can cut from a total length of 58cm

Julli [10]
5600 - 4420 = 1180....so there is a difference of 1180 in a period of (1998 - 1993) = 5 yrs.

1180/5 = 236 people per yr

so in 1998 the population was 5600.....in 2000 (2 yrs later) the population would be : 5600 + 236(2) = 5600 + 472 = 6072 <==
