Answer:
radius = 4 cm
Step-by-step explanation:
To find the length of the radius, we will follow the step below;
First, write down the formula for finding the volume of a cylinder
v=πr²h
where v is the volume of a cylinder
r is the radius and
h is the height of the cylinder
from the question given,
v=125.6 and h = 10 cm
we can now proceed to insert the values into the formula and solve for r
note that π is a constant which is equal to 3.14
v=πr²h
125.6 =3.14×r×10
125.6 =31.4 r
Divide both-side of the equation by 31.4
125.6/31.4 =31.4 r/31.4
4 = r
r =4 cm
The length of the radius = 4 cm
A contractor bought 8.2 ftsquared of sheet metal. She has used 3.5 ftsquared so far and has $141 worth of sheet metal remaining. The equation 8.2xminus3.5xequals141 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answer:
The cost of a sheet metal per square foot is $30
Step-by-step explanation:
Given
Size of Sheet Metal = 8.2ft squared
Used Sheet Metal = 3.5ft squared
Worth of leftover sheet = $141
Equation: [tex]8.2x - 3.5x = 141[/tex]
Required
Find the cost per square foot of the sheet metal
Solving for x in the above equation will give the cost per square foot of the sheet metal.
[tex]8.2x - 3.5x = 141[/tex]
[tex]4.7x = 141[/tex]
Divide both sides by 4.7
[tex]\frac{4.7x}{4.7} = \frac{141}{4.7}[/tex]
[tex]x = \frac{141}{4.7}[/tex]
[tex]x = 30[/tex]
Hence, the cost of a sheet metal per square foot is $30
-4-2/3x= -6 by adding 4 to both sides
Answer:
Yes
Step-by-step explanation:
You have to add 4 on both sides to get X by itself. Then, you solve for X by multiplying the Denominator.

Jo is going to a college where the cost for one year is $11,000. He has a scholarship worth $5,000. He earns $200 a week at his job. How many weeks does he need to work to pay for 50% of the remaining amount?
Answer:
15 Weeks
Step-by-step explanation:
$11,000 - $5,000 = $6,000 This is how much he needs to pay.
$6,000 ÷ $200 = 30 This is how many weeks he needs to work to get the $6,000
The questions is asking how many weeks does he have to work to get %50, Therefore 30 x .50 = 15 which is your answer.
Hope this helps!!!

Mr. Whittaker’s science class uses tide gauges to measure annual variations in water levels at different parts of a river, and then compares those variations to the average annual trend.
Matea recorded that the water level in one part of the river fell 1.05 millimeters per year for 2.48 years.
Which number represents the rate at which the water level fell? -1.05mm/year
Which number should the rate be multiplied by to find the total variation in water level?
2.48 years
that's the correct answer ^
This data will be compared to the average annual trend, which shows the water level rising 1.8 mm/year.
Which number represents the rate at which the water level fell?
Which number should the rate be multiplied by to find the total variation in water level?
Answer:
a) Which number represents the rate at which the water level fell? -1.05mm/year
b) Which number should the rate be multiplied by to find the total variation in water level?
2.48 years
Step-by-step explanation:
Total variation in water level is calculated as the rate at which the water level fell multiplied by number of years are which the water level fell.
Mathematically = Rate at which the water level fell(mm/year) × number of years are which the water level fell (years).
Total variation in water levels can be caused by changes in climate conditions or by human activity.
Hence, for the question above,
rate at which the water level fell is
given as -1.05mm/year and the number that the rate be multiplied by to find the total variation in water level is 2.48 years.
Answer:
Which number represents the rate at which the water level fell?
✔ -1.05 mm/year
Which number should the rate be multiplied by to find the total variation in water level?
✔ 2.48 years

A number is chosen at random from 1 to 10. Find the probability of selecting a 6 or greater.
Answer:
1/2
Step-by-step explanation:
p(event) = (number of desired outcomes)/(total number of outcomes)
How many different outcomes are there? You can choose 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10, so the total number of possible outcomes is 10.
How many outcomes are desired. The desired outcomes are any outcomes with a number 6 or higher. Which numbers are 6 or higher? 6, 7, 8, 9, 10. There are 5 outcomes that are 6 or higher, so there are 5 desired outcomes.
p(event) = (number of desired outcomes)/(total number of outcomes)
p(event) = 5/10 = 1/2
Answer: 1/2

The circumference of a circle is 15.9mm.
Find the length of the radius.
Give your answer rounded to 1 DP.
PLEASE HELP
i will give you brainiest if you can can answer in 3 minutes
Answer:
R = 2.6 mm
Step-by-step explanation:
D = C ÷ π
D = 15.9 ÷ 3.14
D = 5.06
D = 5.1 mm
R = D ÷ 2
R = 5.1 ÷ 2
R = 2.55
R = 2.6 mm
Answer:
r = 2.5 mm
Step-by-step explanation:
The circumference of a circle has the following formula.
circumference = 2πr
where
r = radius
π = 3.14
circumference = 15.9 mm
circumference = 2πr
15.9 = 2 × 3.14 × r
15.9 = 6.28 r
divide both sides by 6.28
r = 15.9/6.28
r = 2.53184713376
Rounding to 1 decimal place
r = 2.5 mm

Em uma caixa há 11 bolas vermelhas e 7 azuis. Ao escolher 4 bolas aleatoriamente, qual a probabilidade de serem todas vermelhas? (A) 1 7 . (B) 7 102. (C) 11 102. (D) 7 18 (E) 11 18
Answer: C. 11/102
Step-by-step explanation:
Given Data:
Red ball = 11
Blue ball = 7
Total no of balls = 18
What is the probability that choosing 4 balls all are red.
1. Probability of picking a red ball
= 11/18
2. Probability of picking a blue ball
= 7/18
3. Probability of picking 4 red balls in a roll.
= 11/ 18 * 10/17 * 916 * 8/15
= 11/102
Or
10.8% chance of all 4 balls being red.
