Set up a ratio:
10 foot tall elephant / X shadow length = 15 foot tall statue / 18 foot shadow.
Cross multiply:
10 * 18 = X * 15
Simplify:
180 = 15x
Divide both sides by 15:
x = 180 / 15
x = 12
The elephants shadow was 12 feet long.
Answer:
186.666... calories for the 14-inch pizza.
Step-by-step explanation:
For the first pizza there's 13.33333333333... calories in 1 in.
For the second pizza you multiply 13.33333333333... by 14.
Equaling 186.6 repeating.
Have a great day!
Answer:
Use SAS to show that triangles PRQ and PRS are congruent.
Step-by-step explanation:
Since PR bisects angle QPS, angles QPR and SPR are congruent. By reflexive property of congruence, PR is congruent to itself. Since PQ is congruent to PS, we can use SAS to show that the two triangles are congruent. By CPCTC, QR is congruent to SR.
Answer:
Step-by-step explanation:
So to do this, you would find the surface area of a box. Since it is a rectangular prism, two sides will always have the same area and so there are 3 different areas. 18*15*2 = 540 and 18*3*2 = 108 and 3*15*2 = 90 and 90 + 108 + 540 = 738 inches
3 : 8....can be written as 3/8
12 lbs of apples were sold
apples / oranges : 3/8 = 12/x
this is a proportion, so we cross multiply
(3)(x) = (12)(8)
3x = 96
x = 96/3
x = 32 <=== 32 lbs of oranges
notice that 3/8 = 12/32....these are equivalent fractions....because that is what proportions are, equivalent fractions
