Find the area of a circle which has a diameter of 26 centimeters.Round to the nearest hundredth (2 spaces beyond the decimal)
Answer:
531 cm^2 approx
Step-by-step explanation:
Given data
Diameter= 26 cm
radius= d/2= 26/2= 13 cm
Area= πr^2
substitute
A= 3.142*13^2
A= 3.142*169
A= 530.998
A= 531 cm^2 approx

Find the mean and median travel times for these students.
If necessary, round your answers to the nearest tenth
Mean: _ minutes
Median: __ minutes
Answer:
mean: 65
median: 9
Step-by-step explanation:
You take all the numbers you have and add them up. Make it simple by adding smaller numbers together. Then once you have the total which is 65 you divide it by the total of numbers you have and then round because after dividing you get 8.125 and the safest way to round is to 9.
How would I do this?
Answer:
Refer to explanation..
Step-by-step explanation:
Since x represent same number when if it is used multiple times..
40 - 3 - 3 = 34 (Find out how many is 4 x)
4x = 34
X = 34 ÷ 4 = 8.5
I don't know what the question is finding for, if it's breadth then it's 8.5, if it is finding length..
Length = 8.5 + 3 = 11.5

During a test flight, Jeri's rocket reached a height of 18 yards. This was 7 yards less than the height of Devon's rocket. Write and solve a subtraction equation to find the height of Devon's rocket.
Answer:
23 yards
Step-by-step explanation:
During a test flight, Jeri's rocket reached a height of 18 yards. This was 7 yards less than the height of Devon's rocket. Write and solve a subtraction equation to find the height of Devon's rocket.
Let us represent the height of Devon's rocket = x
18 yards = x - 7 yards
x = 18 yards + 7 yards
x = 23 yards
The height of Devon's rocket = 23 yards
A large pizza at Palanzio's Pizza starts at $6.80 with a $0.90 charge per extra topping. A large pizza a Guido's Pizza starts at $7.30 with a $0.65 charge per extra topping. How many toppings will need to be added for the price of the pizzas to be the same?
Answer:
Palanzio's Pizza: Y= .90x+6.80
Giudo's Pizza: Y= .65x+7.30
.90x + 6.80= .65x + 7.30
.25x + 6.80= 7.30
.25x = .50

Answer:
1) 1924m²
2) a = (b x h) / 2
(5 x 12) = 60
60 / 2 = 30in²
30in² x 2 = 60in²
area of upper rectangle =
a = l x w
13 x 8 = 104in
area of backer rectangle =
a = l x w
12 x 8 = 96in

+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.
a+b=−4
ab=4
Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 4.

Answer:
We have been given that a car can travel 476 miles on 14 gallons of gas and we are asked to write an equation relating the distance d to the number of gallons g.
We can set an equation as distance traveled is directly proportional to number of gallons used in travelling that distance.
Now we will find out K(number of miles traveled in one gallon of gas) by substituting our given values in this equation.
Therefore, we can see that car travels 34 miles in one gallon of gas.
Now we can use this information to find out how many gallons of gas does this car need to travel 578 miles.
Let us divide number of miles to be traveled by number of miles traveled in one gallon of gas to find out number of gallons of gas needed.
Therefore, car need 17 gallons of gas to travel 578 miles.
Step-by-step explanation:
Step-by-step explanation:
476=14
578=X
578*14/476
8092/476=17
So the answer is 17 gallons
(16/25)-3/2 help me solve
Answer:
-43/50
(decimal) = -0.86
Step-by-step explanation:
Find the LCD which is 50.
16/25 will be multiplied by 2 (because 25 x 2 = 50) so it will then equal 32/50
3/2 will be multiplied by 25 (2 x 25 = 50) = 75/50
subtract them which will give you -43/50

What are m∠1 and m∠2?
A.m∠1 = 30°, m∠2 = 35°
B.m∠1 = 35°, m∠2 = 30°
C.m∠1 = 65°, m∠2 = 60°
D.m∠1 = 85°, m∠2 = 80°
Answer:
B
Step-by-step explanation:
First find the third angle straight linear make 180° so
180°-115°=65°
So 80°+65°+X=180°..triangle measure 180°
145°+X=180
X=180-145
X=35°
The second one. Again straight linear measure 180° so
180°-115°=65°
65°+85°+ Y=180°
150°+ Y=180°
X=180°-150°
Y=30°

You burned a CD of your music and then created an artistic CD label
for it. Your friends liked it so much that they all asked if you would make CD labels
for the CDs of their music. So far, it has taken you 6.5 hours to create 3 CD labels.
How long will it take to create 4 more labels? Round your answer to the nearest tenth.
Answer:
I think it's 8.7
Step-by-step explanation:
if you divide 6.5 by 3, you get 2.16666666667, so that is how long it takes to make 1 CD liable. Multiple that by 4 and round and you get 8.7.
If I'm wrong I apologize :(
