2. The volume of a cylinder varies jointly with its height and the square of the radius. A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. Another spice container is 3 inches tall with a radius of 1.5 inches, what would be the volume?
Answer:
Volume=21.195 cubic inch
Step-by-step explanation:
The volume of a cylinder varies jointly with its height and the square of the radius is expressed as
V∝hr^2
Introducing our constant of proportionality,K we have that
V =Khr^2
Given that A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. We have that
V =Khr^2
7.85=K 2.5 X 1^2
K=7.85/2.5 x1
K=3.14
Given that another spice container is 3 inches tall with a radius of 1.5 inches, Volume=?
V =Khr^2
V=3.14 X 3 X 1.5^2
V=21.195 cubic inch

The student has distributed the second parenthesis by 1 instead of - 1
(b)
Given
(x² - 3x + 4) - (x³ + 7x - 2)
distribute the first parenthesis by 1 and the second by - 1, that is
= x² - 3x + 4 - x³ - 7x + 2 ← collect like terms
= - x³ + x² - 10x + 6

Is 9/10, 1 1/5, 1 1/2 a right triangle?
Answer:
using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2
a²+b²=c²
(9/10)²+(11/5)²=(11/2)²
81/100+121/25=121/4
lcm of 25 and 100 =100
(81+484)/100=121/4
565/100=121/4
113/20=121/4
since they are not equal therefore it's not a right angle triangle

Answer:
The properties of trapezoid apply by definition (parallel bases).
The legs are congruent by definition.
The lower base angles are congruent.
The upper base angles are congruent.
Any lower base angle is supplementary to any upper base angle.
The diagonals are congruent.The bases are parallel by definition.
Each lower base angle is supplementary to the upper base angle on the same side.

Step-by-step explanation:
Proportional
Answer:
y=1
Step-by-step explanation:
Because they are proportional, the two points have to be equal if they were like a fraction. This means (15,3) would be 15/3 which is equal to 5. The other point is (5,?), so that means that the point will have to be 1. This is because then the point will be equal to 5.

Answer:
105
Step-by-step explanation:
To find the surface area, we need to find the area of all the sides. There are five sides, but four of them are exactly the same.
To find the area of a triangle, you need to do width x height / 2. The width is five and the height is eight. 5 x 8 / 2 = 20. There are three more sides that have the exact same area as this. Since there are four sides that have a surface area of twenty, we do 20 x 4 = 80. Then, we find the area of the bottom piece. To find the area of a square, you need to do length x width. 5 x 5 = 25. Then, we add our two areas to get the final result. 80 + 25 = 105. Therefore, 105 is the surface area of the pyramid.
