Answer:
The area of triangle DEF is
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its heights is proportional and this ratio is called the scale factor and the ratio of its areas is equal to the scale factor squared
step 1
Find the scale factor
Let
z ----> the scale factor
----> ratio of its heights
step 2
Find the area of triangle DEF
Let
z ----> the scale factor
x ----> the area of triangle DEF
y ----> the area of triangle ABC
so
we have
substitute and solve for x
You will need exactly 128 pieces of candy to go on all the cookies.
Step-by-step explanation:
To get to this conclusion you will need to use multiplication to determine the outcome.
Since there are 32 cookies for 8 of your friends and each cookie needs 4 pieces of candy you will need to multiply the pieces of candy per cookie.
32×4=128
Each friend will get 4 cookies each. You will get this conclusion by using division.
32÷8 = 4

Answer:
Step-by-step explanation:
Set this up as a ratio of number of cakes to cups of sugar, C:S
Then the ratio given is 1:2.5 which says 1 cake takes 2.5 cups of sugar. We want to know how many cakes, x, will be made with 37.75 ups of flour:
and cross multiply to solve:
2.5x = 37.75 so
x = 15.1 cakes or just 15 cakes (cuz you can't make one-tenth of a cake!)
<span>We first calculate the annual straight-line depreciation for the starting 8-year useful lifespan. This is given by the value minus the salvage value (23,000 - 1,500) divided by the 8 year lifespan, resulting in annual depreciation of 2,687.50 dollars. After four years at this rate, the vehicle has depreciated in value by 2,687.50 * 4 dollars (10,750) and has a present value of 12,250 dollars. The useable life is then reduced by 2 years so we must recalculate the straight-line depreciation. This is given by present value minus salvage cost (12,250 - 1,500) divided by the remaining 2 years of usable life. This results in a depreciation expense in both years 5 and 6 of $5,375.</span>
