Answer:
-3
Step-by-step explanation:
40=16-8r
Subtract 16 from both sides.
24=-8r
Now divide by -8
-3=r
Answer:
-3= r
Step-by-step explanation:
40= 16- 8r
subtract 16 from both sides
40-16= 16 - 16 -8r
24= -8r
divide both sides by -8
24/-8 = -8r/-8
-3= r
The formula for the surface area of a cylinder is 2\pi r(r+h)2πr(r+h)2, pi, r, left parenthesis, r, plus, h, right parenthesis where rrr is the radius of the cylinder's base and hhh is its height. A certain pole has a cylinder-like shape, where the base's radius is 101010 centimeters and the height is 222 meters. What calculation will give us the estimated surface area of the pole in square centimeters?
Answer:
2pi x 10 x 210
Step-by-step explanation:
The estimated surface area of the pole is 13194.68 square centimeters and this can be determined by using the given data.
Given :
The formula for the surface area of a cylinder is [tex]2\pi r(r+h)[/tex].A certain pole has a cylinder-like shape, where the base's radius is 10 centimeters and the height is 2 meters.The following steps can be used in order to determine the surface area of the pole in square centimeters:
Step 1 - According to the given data, the surface area of a cylinder is [tex]2\pi r(r+h)[/tex].
Step 2 - Now, substitute the values of 'r' and 'h' in the expression of the area of the cylinder.
[tex]A = 2\pi\times 10\times (10+200)[/tex]
Step 3 - Simplify the above expression.
[tex]A = 2\pi\times 10\times (210)[/tex]
[tex]A = 13194.68\; {\rm cm^2}[/tex]
So, the estimated surface area of the pole is 13194.68 square centimeters.

If Jamie is riding at 14 mph and cori is riding at 0.04km per minute, how far will each of yjem bike in two hours? 1 mile = 1.61 km use the equation D=V/T
Answer:
Jamie will have covered a distance of 45.08 km while Cori will be 4.8 km away
Step-by-step explanation:
Here, we want to know how far will each of both riders be in 2 hours time.
Jamie is riding 14 mph
This means the number of miles covered in two hours will be 14 mph * 2 = 28 miles
For comparison purposes, let’s convert this to kilometer.
Since 1 mile = 1.61 km, then 28 miles will be 28 * 1.61 km = 45.08 km
For Cori, he is riding at 0.04 km per minute
1 hour = 60 minutes
so 2 hours = 2 * 60 = 120 minutes
Since the speed is 0.04 km in a minute
Then the distance in 120 minutes will be 0.04 * 120 = 4.8 km
Answer:
The answer is B.
Step-by-step explanation:
0.40 km to miles 0.248548
Then 0.248548 x 120=2 hours
a) The radius of a circular field is 42 m. Find the perimeter of the field. Also find the length of wire required to fence it with 5 rounds
263.89
263.89*5=1319.45
We are given with the radius of the circular field,
[tex]r = 42 \: m[/tex]
And, we have to find the perimeter of the field. Also, we have to find the length of the wire required to fence it with 5 rounds:
We know,
Perimeter of a circle = 2πr, where r is the radius of the circle, So let's find the perimeter by using this formula.
[tex]perimeter = 2\pi r[/tex]
[tex]perimeter = 2 \times \dfrac{22}{7} \times \: 42 m[/tex]
[tex]perimeter = 2 \times 22 \times 6 \: m[/tex]
[tex]perimeter = \boxed{264 \: m}[/tex]
Now, finding the length of the wire which is equals to 5 × Perimeter of the circular field.
[tex]length \: of \: wire = 264 \: m \times 5[/tex]
[tex]length \: of \: wire = \boxed{1320 \: m}[/tex]
And we are done !!

Step-by-step explanation:
Marlene brought a pitcher filled with 10 cups of water to her volleyball game. The paper cups she brought hold Two-thirds of a cup of water each. How many paper cups can Marlene fill with water?
Which math sentence represents the problem?
Two-thirds divided by 10 = 20/30=1/15
10 divided by two-thirds = 30/2=15
10 divided by three-halves = 20/3] 6 and two-thirds
1/10 divided by two-thirds = 3/20
Marlene needs 15 paper cups to fill with water
An equation is an expression that is used to show the relationship between two or more variables and numbers.
Since each paper cups can hold Two-thirds of a cup of water, hence to hold 10 cups of water:
Number of water cups = 10 cups / (two- thirds) = 10 * 3 / 2 = 15
Marlene needs 15 paper cups to fill with water.

Step-by-step explanation:
The sum of five consecutive integers is five. What is the product of the five integers?
The first integer = x
The second integer = x + 1
The third integer = x + 2
The fourth integer = x + 3
The fifth integer = x + 4
Since they all add up to 5, let's set them equal to 5
x + x + 1 + x + 2 + x + 3 + x + 4 = 5
Combine like terms
5x + 10 = 5
Subtract 10 from both sides
5x = -5
Divide each side by 5
x = -1
The first integer = x = -1
The second integer = x + 1 = -1 + 1 = 0
The third integer = x + 2 = -1 + 2 = 1
The fourth integer = x + 3 = -1 + 3 = 2
The fifth integer = x + 4 = -1 + 4 = 3
We can check this by adding all the integers together and making sure we get 5
3 + 2 + 1 + 0 - 1 = 5
Answer:
0
Step-by-step explanation:
If the sum of the integers is 5, then the arithmetic mean of the integers is [tex]$\frac{5}{5}=1$[/tex] . In five consecutive integers, the arithmetic mean is equal to the middle integer, which means the integers are -1, 0, 1, 2, 3 and the product is [tex]$\boxed{0}$[/tex].

Dominic is making meatballs. He uses 3/4 cup of breadcrumbs for every 1 1/4 pounds of ground beef. How many cups of breadcrumbs does he need when he uses 1 3/4 pound of ground beef? Show your work.
Answer:
1 1/20
Step-by-step explanation:
¾ / 1 ¼= ¾ / 5/4= ¾ x ⅘ = 12/ 20= ⅗
⅗ x 1 ¾ = ⅗ x 7/4 = 21/20= 1 1/20
Domonic needs 1 1/20 cups of breadcrumbs when he uses 1 ¾ pounds of ground beef.
[tex]$1 \frac{3}{4}[/tex] pound of ground beef requires [tex]$1 \frac{1}{20}[/tex] cup of breadcrumbs.
We have Dominic who uses 3/4 cup of breadcrumbs for every 1 1/4 pounds of ground beef.
We have to determine how many cups of breadcrumbs does he need when he uses 1 3/4 pound of ground beef.
If you solve 5 questions of mathematics in 2 hours. Then how many questions you will solve in 6 hours ?You will solve - 5 x [tex]$\frac{6}{2}[/tex] = 15 questions.
According to the question, we have -
[tex]$\frac{3}{4}[/tex] cup of breadcrumbs for → [tex]$1\frac{1}{4}[/tex] = [tex]$\frac{5}{4}[/tex] pounds of ground beef.
1 cup of breadcrumbs for → [tex]$\frac{\frac{5}{4} }{\frac{3}{4} }[/tex] = [tex]$\frac{5}{3}[/tex] pounds of ground beef.
This means -
[tex]$\frac{5}{3}[/tex] pounds of ground beef requires → 1 cup of breadcrumbs.
1 pound of ground beef requires → [tex]$\frac{3}{5}[/tex] cup of breadcrumbs.
[tex]$1\frac{3}{4} =\frac{7}{4}[/tex] pounds of ground beef requires → [tex]$\frac{3}{5}\times \frac{7}{4} =\frac{21}{20} =1 \frac{1}{20}[/tex] cup of breadcrumbs.
Hence, [tex]$1 \frac{3}{4}[/tex] pound of ground beef requires [tex]$1 \frac{1}{20}[/tex] cup of breadcrumbs.

Answer:
the missing value is 9.33.
Step-by-step explanation:
given,
length (l) = 3x+2
breadth (b) = 4
perimeter(P) = 68 cm
now,
P = 2(l+b)
or, 68 = 2× ( 3x+2+4)
or, 68 = 2× ( 3x+ 6)
or, 68 = 6x+12
or, 68 - 12= 6x
or, 56 = 6x
or, 6x = 56
or, x = 56/6
or, x = 9.33
