Answer: -3 + 4 = 1

==================================================

Explanation:

We start at the bottom layer.

That arrow on the bottom layer goes from 0 to -3. In short, it represents the number -3.

The upper arrow moves from -3 to +1 or simply 1. This is a distance of 4 spaces. So we add on 4.

Overall, this diagram represents -3+4 = 1

Isabel can drive 505.85 miles with a gas tank that holds 15.1 gallons of gas

Solution:

Given that, Isabel’s car gets 33.5 miles per gallon

Her gas tank holds 15.1 gallons of gas

To find: Number of miles can Isabel drive on a full tank of gas

Let "x" be the miles drive with 15.1 gallons of gas

From given,

1 gallon = 33.5 miles

15.1 gallon = x miles

This forms a proportion and we can solve the sum by cross multiplying

$1 \times x = 15.1 \times 33.5\\\\x = 505.85$

Thus Isabel can drive 505.85 miles on a full tank of gas

B) The perimeter of the shape is 25.71 cm

natita [175]

Answer:

$r=4cm$

Step-by-step explanation:

Having the radius to be involved, the shape is a circle.

Circumference formula

$c=2\pi r$

Finding radius, formula will be reversed.

$r=\frac{25.72cm}{2\pi }$

$r=\frac{25.71cm}{2(3.142)}$ $r=\frac{25.71cm}{6.284}$ $r=4.09cm$

How to turn .9% into ratio

leonid [27]

Answer:

9:100

Step-by-step explanation:

Turn 9% into a fraction by putting it over a hundred:

9/100

Then simply change the '/' into ':'

If this were another fraction, let's say, 4/6, then you'd put it in simplest form, which is 2/3 = 2:3
