It’s closer to 0.4, because if you place it on a number line, you can see that it is before 0.45; the halfway point.

Answer:

1. $\frac{7^8}{7^6}=49$

2. 7

3. 18

Step-by-step explanation:

Question 1:

Given:

The expression to simplify is $\frac{7^8}{7^6}$ .

We use the property of exponent $\frac{a^m}{a^n}=a^{m-n}$

Therefore, $\frac{7^8}{7^6}=7^{8-6}=7^2=7\times 7 = 49$

Question 2:

Given:

The expression to simplify is $7(\frac{1}{2}+\frac{1}{2})$ .

We add the fractions first inside the parenthesis.

So, $\frac{1}{2}+\frac{1}{2}=\frac{1+1}{2}=\frac{2}{2}=1$

Now, $7(1)=7$

Question 3:

The first five prime numbers are 1, 2, 3, 5, and 7.

Therefore, the sum of these five numbers is given as:

$1+2+3+5+7=18$

a rectangular picture frame has a width of 9 cm and a length of x cm. which expression represents the perimeter of the picture f

Scrat [10]

Perimeter of rectangle is calculated by using formula 2*(a+b) where "a" and "b" are dimensions of rectangle (its width and height). If we replace "a" with "x" and "b" with "9" as those are dimensions of the frame the answer is 2*(x+9) which is the same as 2*x + 18.
