9n + 15 < = 10n + 24
9n - 10n < = 24 - 15
-n < = 9
n > = -9
Volume of a cylinder = π r² h
Let us assume the following values:
radius = 9
height = 10
Volume = 3.14 * 9² * 10
= 3.14 * 81 *10
Volume = 2,543.40
Changes:
radius is reduced to 2/9 of its original size = 9 x 2/9 = 2
height is quadrupled = 10 x 4 = 40
Volume = π r² h
= 3.14 * 2² * 40
= 3.14 * 4 * 40
Volume = 502.40
Original volume = 2543.40 V.S. Volume after change = 502.40
The volume of an oblique cylinder decreased when its radius was decreased to 2/9 of its original size and its height is increased 4 times.
A) since the ratio of green peppers to pureed tomatoes is 1:4, the tomatoes have 4 times the amount of mL as the peppers, so there are 20mL of green peppers he should mix with 80 mL of pureed tomatoes.
Answer:
The teacher can hand out pizza to 8 students.
Step-by-step explanation:
To find how many slices of pizza the teacher can hand out , you can divide 7 by 7/8 and round down the nearest whole number.
7 ÷ 7/8 = 8
8 is already a whole number. No need to round down.
The teacher can hand out pizza to 8 students.
Answer:
The expression simplifies to .
Step-by-step explanation:
The expression
can be rearranged and written as
In this form the terms in the numerator and in the denominator cancel to give
The are present both in the numerator and in the denominator, so they also cancel, and the fraction simplifies to , so finally our expression becomes:
