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
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
(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
In triangle ABC, the measure of C is 90°,
AC=24, and BC=10. What is the value of sin
A?
Answer:
Sin A = 0.38462
Step-by-step explanation:
From the trigonometric function,
Sin A = [tex]\frac{Opposite}{Hypotenuse}[/tex] ................... 1
So that, applying the Pythagoras theorem to determine the value of hypotenuse,
[tex]/Hyp/^{2}[/tex] = [tex]/Opp/^{2}[/tex] + [tex]/Adj/^{2}[/tex]
= [tex]24^{2}[/tex] + [tex]10^{2}[/tex]
= 576 + 100
[tex]/Hyp/^{2}[/tex] = 676
Hyp = [tex]\sqrt{676}[/tex]
= 26
The hypotenuse of the triangle is 26.
Thus, from equation 1;
Sin A = [tex]\frac{10}{26}[/tex]
Sin A = 0.38462

Answer:
2) 520
3) 135
4) 490
5) 850
Step-by-step explanation:
2) 10 regular for every 2 premium. so 12 total. Then we do 624 divided by 12 so we get 52. So we multiply 10 by 52 and 520. So they have 520 regular subscribers.
3) 3 short sleeves for every 9 long sleeves. So 12 in total. 540 divided by 12 is 45. 45 times 3 is 135. So 135 short sleeves were sold.
4) 7 teens for every 2 adults. so 9 in total. 630 divided by 9 is 70. 70 times 7 is 490. So 490 of the people who voted were teens.
5) For every 10 songs he like there was 5 he disliked. So 15 in total. 1275 divided by 15 is 85. 85 times 10 is 850. He liked a total of 850 songs.

Sam has 2 1/2 pounds of blueberries. Ben also has some blue berries. Together, they have 4 2/3 pounds of blueberries.
Answer:
2 1/6 berries
Step-by-step explanation:
Sam has 2 1/2 pounds of blueberries. Ben also has some blue berries. Together, they have 4 2/3 pounds of blueberries
Total number of berries = Number did berries Sam has + Number of Berries Ben had
The number of berries Ben had =
4 2/3 - 2 1/2
2 ( 4 - 3/6)
2 1/6 berries
just the answer Please hurry
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

Answer:
1. complementary
2. not complementary or supplementary
3. not complementary or supplementary
4. complementary
5. supplementary
Step-by-step explanation:
You can tell if two angles are complementary if their combined angle values add up to 90 degrees
[tex]A+B=90[/tex]
You can tell if two angles are supplementary if their combined angle values add up to 180 degrees
[tex]A+B=180[/tex]
If they don't add up to these values then they are neither complementary nor supplementary

Value of x? I need this very quickly.ASAP.
Answer:
x = 5
Step-by-step explanation:
The sum of the angles of a triangle is 180°.
(180 - 18x + 5) + (-1 + 8x) + 46 = 180
⇒ 180 - 18x + 5 - 1 + 8x + 46 = 180
⇒ -10x + 230 = 180
⇒ -10x = -50
⇒ x = 5

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
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.

A Mars rover descended from the rim of a crater at a constant rate. After 2 days, the rover's elevation was 106 meters. After 6 days, its elevation was 48 meters. What elevation did the rover start at? ____meters Complete the equation that describes the relationship between the rover's elevation in meters, E, and the elapsed time in days, t. Write your answer using whole numbers or decimals rounded to the nearest tenth. E= ___ t+____
Answer:
135
E = - 14.5t + 135
Step-by-step explanation:
Given that, descent rate is constant ;
Elevation after 2 days = 106 m
Elevation after 6 days = 48 m
Let
Rate of elevation per day= x
Initial elevation = a
Hence,
a - 2x = 106 - - - (1)
a - 6x = 48 ___(2)
-2x + 6x = 106 - 48
4x = 58
x = 58/4
x = 14.5 meters per day
Hence, initial elevation :
a - 2(14.5) = 106
a - 29 = 106
a = 106 + 29
a = 135
Relationship between Rover's elevation, E and elapsed time, t
E = - 14.5t + 135
-14.5 = rate per day

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
