The area of a rectangle is 560 square inches. The length is 3 more twice the width. Find the length and width.
Answer:
l = 35 inches and b = 16 inches
Step-by-step explanation:
Let length be b and width be b.
The area of a rectangle is 560 square inches.
Length is 3 more twice the width.
l = 2b+3 ....(1)
We know that,
Area = length × width
560 = (2b+3)b
[tex]2b^2+3b-560=0\\\\b=16,-17.5[/tex]
Put b = 16 in equation (1).
l = 2(16)+3
= 35 inches
So, the length is 35 inches and the width is 16 inches.
The probability of randomly selecting two oranges from a bowl of 5 oranges and 4 tangerines if the first selection is replaced
Answer:
25/81
Step-by-step explanation:
The probability of randomly selecting two oranges = (number of oranges in the bowl / total number of fruits in the bowl) x (number of oranges in the bowl / total number of fruits in the bowl)
total number of fruits in the bowl = 5 + 4 = 9
5/9 x 5/9 = 25/81

Alfonso plans to create an ice sculpture out of a 8-cubic foot ice cube. What is the surface area of the cube?
Answer:
Surface area of cube = 24 ft²
Step-by-step explanation:
Given:
Volume of cube = 8 ft³
Find:
Surface area of cube
Computation:
Volume of cube = Side³
Side³ = 8 ft³
Side³ = (2 ft)³
Side = 2 ft
Surface area of cube = 6a²
Surface area of cube = 6(2)²
Surface area of cube = 6(4)
Surface area of cube = 24 ft²
A cylinder with the height of 6km has a volume of 384km3 what is the radius?
Answer:
r = 8
Step-by-step explanation:
V = π r^2 h so 383 = r^2 (6)
383 / 6 = r^2
64 = r^2 so
r = 8
can somebody help with this??????
Answer:
6
Step-by-step explanation:
The equation can be made more clear by changing the form.
g(h(0)) = ?
All we have to do is find the y values for an x value of 0
h(x) = x^2 - 3
h(0) = 0^2 - 3
h(0) = -3
So now we plug in -3 for g(x)
g(x) = -2x
g(-3) = -2(-3)
g(-3) = 6
What’s the answer????

Sally's huge dog weighed 175 pounds in 2018 and then weighed 145 pounds in 2020. What was the rate of change in weight?
pounds per year?
Answer: 15 lbs per year
Step-by-step explanation:
Huge dog lost 30 lbs in a span of 2 years so divide to find rate of change which is 15lbs per year
Answer: -15 pounds per year
Step-by-step explanation:
We can first list out all the information like Year, Weight
so (2018, 175) and (2020,145)
It asks to find the slope, so we just use the slope formula
175-145/2018-2020 = 30/-2 which is -15
