Given:
15% of its height each day
27 inches on day 10.
How tall was it yesterday?
27 represents 115% of the height yesterday. So we divided 27 by 115% to get yesterdays height.
27 ÷ 115% = 23.48 inches.
The plant was 23.48 inches tall yesterday.
To check:
23.48 x 15% = 3.52 inches
23.48 + 3.52 = 27 inches
Answer: 17160 feet
Step-by-step explanation:
We know that 5280 feet = 1 mile
So all we have to do is multiply 3 1/4 by 5280
Let's split the 3 and 1/4 up to make the multiplication easier
3×5280=15840
×5280=
Now add them together
15840+1320=17160
Answer:
(15x-2)°+( 7x+4)°=90° --> 15x-2°+7x+4°=90° --> 22x+2°=90° --> 22x=90°-2° --> 22x=88° --> x=88/22 --> x=4.
m/_BAC=(15x-2)°=15×4-2 =58°
m/_CAD=(7x+4)°=7×4+4= 32°.
Answer: $284.80
look when you are trying to find the percent of a number you need to turn the percent into a decimal then multiply the decimal by the number:
1st. 40% as a decimal is 0.40 because as a fraction 40% is 40/100 so that means that 1.00 is 100 and 0.40 is 40%
2nd. Next, you do 0.40 x 712.00 = or
712.00
x 0.40
______
$284.80
