Answer: 1.5 square units
The area of the whole rectangle is 3 units. Area is found by multiplying length by width. Only half of the rectangle is shaded, so if you take the whole area of the rectangle, and divide it in half, you get the area of that half rectangle.
By doing this, you divide 3 in half, and get 1.5 square units.
Hope this helps :)
M = T
3x + 20 = 5x - 4
Subtract 3x from both sides.
20 = 2x - 4
Add 4 to both sides.
24 = 2x
Divide both sides by 2.
x = 12
We don't know how to find what A or H is equal to, but we at least know what x is equal to.
Answer: Option A
About 0.02 pounds
Step-by-step explanation:
We know that density is defined as:
Where
d is the density
m is the mass
v is the volume
We want to calculate the helium-air mass of a spherical balloon and we know its density and the diameter of the balloon.
Then we can calculate its mass.
1) We use the diameter of the spherical globe to calculate its volume.
The volume of a sphere is:
and
So
2) Use the density formula to find the mass
<em>The answer is 0.02 pounds</em>
Answer:
75.6 ounces
Step-by-step explanation:
Step one.
Given data
we are told that the original quantity of food is 63 ounces
and the increase is in food is by 20%
Step two:
let us find the increase in ounces
=20/100*63
=0.2*63
=12.6 ounces
Hence the amount of food in the bag now is
=12.6+63
=75.6 ounces
