Step-by-step explanation:
Volume= [tex]\frac{4225pi }{3}[/tex]ft³
Height= 25
Volume= πr²[tex]\frac{h}{3}[/tex]
Volume= 3.14 ×r²×[tex]\frac{25}{3}[/tex]
[tex]\frac{157}{6}[/tex] r²= [tex]\frac{4225pi }{3}[/tex]
r²= [tex]\frac{4225\pi }{3}[/tex] × [tex]\frac{6}{157}[/tex]
r²= 169 (estimate)
r=√169
r= 13

Step-by-step explanation:
Just divide 95 by 7 yes you heard me right then multip,y by 760 you can use calculator to get 56
The width of a rectangle is 5 inches. The length of the rectangle is twice the width. Find the perimeter of the rectangle.
PLZZZZZZZZ HELP
Answer: the perimeter of the rectangle is 30
Step-by-step explanation: so we know that the width of the rectangle is 5. Then it says that the length is two times more than the width....
5 times 2
Which is 10
Now all is left, you find the perimeter (all sides)
5+5+10+10
10+20
30
Therefore,
The perimeter of the rectangle is 30
Answer: 30
Step-by-step explanation: If the width is 5 and the length is twice the width then the length is going to be 10.

What is BODMAS Rule?BODMAS rule is the rule used when solving expressions involving more than one operations.
It is the abbreviation of Brackets, Order, Division, Multiplication, Addition, Subtraction, which is the order of the operations to be done.
The given expression is 8³ - 10 × 5 - 4.
We know the rule of BODMAS.
since the given expression includes more than one operations, we have to follow the rule of BODMAS.
There are no brackets in the expression.
There is a power of 3 for the base 8.
We should perform that in the first step.
8³ - 10 × 5 - 4 = 512 - 10 × 5 - 4
Next we do the operation of multiplication.
512 - 10 × 5 - 4 = 512 - 50 - 4
There is subtraction.
512 - 50 - 4 = 566
Hence the operation of the power is done first.

What scenario could be modeled by the graph below?
A. The number of pounds of apples, y, minus two times the number of pounds of oranges, x, is at most 5.
B. The number of pounds of apples, y, minus half the number of pounds of oranges, x, is at most 5.
C. The number of pounds of apples, y, plus two times the number of pounds of oranges, x, is at most 5.
D. The number of pounds of apples, y, plus half the number of pounds of oranges, x, is at most 5.
Answer:
I would believe that it is A.
Step-by-step explanation:
The fact that A has 5, and x is minus two times, 5/2= 2.5, and that is where the second arrowhead is pointing to on the x axis.
The number of pounds of apples, y, minus two times the number of pounds of oranges, x, is at most 5 which is correct option (A).
What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is a Linear Function?A linear function is defined as a function in the form of f(x) = mx + bc where 'm' and 'c' are real numbers.
It represents the line's slope-intercept form, which is written as y = mx + c.
This is because a linear function represents a line, i.e., its graph is a line. Here,
'm' is the slope of the line
'c' is the y-intercept of the line
'x' is the independent variable
'y' (or f(x)) is the dependent variable
According to given graph,
A has a value of 5, and since x is negative two times, 5/2=2.5, which is where the second arrowhead on the x axis is pointing.
So, the total number of the pounds of apples, y minus two times, and the pounds of oranges, x, equals at most five pounds.
Hence, the number of pounds of apples, y, minus two times the number of pounds of oranges, x, is at most 5.

Answer:
320
Step-by-step explanation:
The formula for the volume of a pyramid is V= (b x h)/3
v is the volume
b is the base you get it by multiplying the bases length and width in this case it would be 80 in( since 8 x 10 is 80)
h is the height in this case it would be 12 in
V= (b x h)/3
V= (80 x 12)/3
V= (960)/3
V= 320 in

B) David and Andrew are traveling to a Mathematics conference. David travels 110 miles in the same time that Andrew travels 140 miles. Andrew travels 15 miles per hour faster than David. Find the average rate of each person.
Answer:
David's average speed is 55 mph and Andrew's average speed is 70 mph
Step-by-step explanation:
Let David's speed be s.
Average speed is given as:
speed = distance / time
They both spent the same time, t.
David's speed is:
s = 110 / t
=> t = 110 / s
Andrew travels 15 mph faster than David.
Andrew's speed is:
(15 + s) = 140 / t
=> t = 140 / (15 + s)
Therefore, since they spent the same time:
110 / s = 140 / (15 + s)
Cross multiply:
110(15 + s) = 140s
1650 + 110s = 140s
1650 = 140s - 110s
30s = 1650
s = 1650 / 30
s = 55 mph
Andrew's speed is:
15 + 55 = 70 mph
Therefore, David's average speed is 55 mph and Andrew's average speed is 70 mph.

4th question help plzz with steps
I give brainly
Answer:
72 degrees
Step-by-step explanation:
A central angle equals the degree of the arc.
If the circumference is 20 and the arc is 4 than means the
arc is 4/20= 1/5 of the circumference.
A circles circumference is also always equal to 360 degrees.
So we need to find out what 1/5 of 360 is to find the degree of the arc.
So then 1/5*360= 72
so the Arc is equal to 72 degrees of the whole circle, which means the central angle is equal to 72 degrees as well.

If the volume of a cylinder 30 cm high 4620cm^3 find radius
Answer:
7 cm to 1 decimal place
Step-by-step explanation:
We need to know one formula in order to solve this question and it's the volume of a cylinder formula which is π × r² × h where 'r' is the radius and 'h' is the height, we want to work out the radius not the volume so we have to set up an equation to solve for the radius given the information that the volume of the cylinder is 4620 cm³ and the height is 30cm so
→ Step 1 form the equation
π × r² × h = 4620
→ Step 2, substitute in the values in this case we only need to substitute in the height
π × r² × 30 = 4620
→ Step 3, divide 30 from both sides to isolate π and r²
π × r² = 154
→ Step 4, divide both sides by π to isolate r²
r² = 154 ÷ π
r² = 49.0197224723
→ Step 5, square root both sides to isolate 'r'
r = 7.0014086063
So the radius of the cylinder is 7 cm to 1 decimal place
Answer:
7.00 cm.
Step-by-step explanation:
V = π r^2 h so
r^2 = V / π h
r = +√(V / πh)
r = +√( 4620 / 30π)
r = 7 .00cm.

Step-by-step explanation:
A veterinarian knows that a 50-pound dog gets 0.5 milligram of a certain medicine, and that the number of milligrams, m, varies directly with the weight of the dog, w. The vet uses these steps to find the amount of medicine to give a 10-pound dog.
Step 1 Find the constant of variation.
k = StartFraction 0.5 Over 50 EndFraction = 0.01
Step 2 Write the direct variation equation.
m = 0.01 w
Step 3
Substitute 10 into the equation to find the dosage for a 10-pound dog.
10 = 0.01 w
Step 4
Solve for w.
10 = 0.01 w. w = 1000.
The 10-pound dog needs 1000 milligrams.
In which step did the veterinarian make the first error?
In the third step, 10 is the mass of the dog. As such, it should have been substituted to w and not to m.

If 45 kids selected 'Shin Chan', how many students are there in the class totally?
Answer:
There were 60 kids in class.
Step-by-step explanation:
Since the kids had two choices and the ratio between them was for every 3 children that selected "Shin Chan" only 1 selected "Tom and Jerry", then in order to calculate the number of children in the class if 45 kids selected "Shin Chan", we first need to calculate the number of children that selected the other option. To do that we divide the number by 3. We have:
children(Tom and Jerry) = children(Shin Chan)/3
children(Tom and Jerry) = 45/3 = 15
Therefore the number of children in the class is:
children(class) = children(Tom and Jerry) + children(Shin Chan)
children(class) = 15 + 45 = 60
There were 60 kids in class.
