Answer:

200% of 7.50 is 15.00

200% more than 7.50 is 15 + 7.5 = 22.50

Step-by-step explanation:

100% of 7.50 is 7.50

another 100% is 7.50

so 200% is 15.00

200% of a value is the value multiplied by 2

200% more than 7.50 is 15.00 + 7.50 = 22.50

Answer:

Step-by-step explanation:

You will move the 7 to 18 but bc there is a equal sign you will change the positive sign to negative and just solve -7 plus 18 you will get 11 and that’s b

45 620 000 to the nearest million

aniked [119]

Answer:

46,000,000 (46 million)

Step-by-step explanation:

If the number to the right (in this case the hundred thousands place) is 5 or greater then you round up.

If it was lower than 5 you would round down.

As the number in the hundred thousands place is 6, this means we can round up.

Answer: m

Step-by-step explanation:

if you are talking about a specific point, then it would be m because OA, AB and

<-->

all have other points to them.

AB is when you are trying to explain the distance between AB

m would be used just to figure out where that point on the grid really is

A box has a volume of 546cm3 and a surface area of 422cm2. What are the Length, Width and Height?

Klio2033 [76]

We know that the formula for the volume of a box is:

$V =lwh$

Where:
l = length
w = width
h = height

The formula of the surface area of a box is:
$SA=2(lw+lh+wh)$

Based on the given we know the following:
$546cm^{3} =lwh$

and

$422cm^{2}=2(lw+lh+wh)$

If we factor out the given volume, you can come up with 3 numbers that will satisfy the surface area formula:

$546=6*7*13$

Let:
l = 6cm
w = 7cm
h = 13cm

Now let's try this on the surface area formula:
$422cm^{2}=2(lw+lh+wh)$
$422cm^{2}=2((6cm*7cm)+(6cm*13cm)+(7cm*13cm))$
$422cm^{2}=2(42cm^{2}+79cm^{2}+91cm^{2})$
$422cm^{2}=2(211cm^{2})$
$422cm^{2}=422cm^{2}$

The answer is then:
l = 6cm
w = 7cm
h = 13cm

Any order would be fine.
