A truck travels 2,400 miles in 60 hours, going the same distance each hour.
How many miles does the truck travel each hour?
A. 3 miles
B. 60 miles
C. 6 miles
D. 40 miles

Answers

Answer 1
2400miles/60hours
40miles/hour
Answer is D
Answer 2

The truck travels D) 40 miles per hour

What is the speed of an object?

Speed of an object is given by the distance travelled divided by time taken to traverse that distance , S = Distance/ time

Given here, distance = 2,400 miles and time taken= 60 hours

therefore speed = 2400/60

                           = 40 miles per hour

Hence, the truck travels 40 miles every hour.

If x (x+y) = 27 and y (x+y) = 54, what is the value of (x+y)^2?

Answers

Answer:

9x^2

Step-by-step explanation:

It is given that:

x ( x + y ) = 27

If one manipulates the equation, by dividing by x, they get:

x + y = 27/x

It is also given that:

y ( x + y ) = 54

Again, manipulate the equation, only this time, divide by y,

x + y = 54/y

It is obvious that;

x + y = x + y

Yet this was proven;

x + y = 27/x

x + y = 54/y

Therefore, the following has to be true;

27/x = 54/y

To sove the proportion, use cross products;

27/x = 54/y

54x = 27y

Inverse operations:

54x = 27y

/27     /27

y = 2x

Substitute;

(x + y)

y = 2x

= (x + 2x)

= 3x

Now solve:

(3x)^2

9x^2

If x=27 and y=54, add them together then multiply by 2 and get 162

14% of 120

[tex]\text{Explain in detail, please!}[/tex]
[tex]\big\text{:)}[/tex]

Answers

Answer:

16.8

Step-by-step explanation:

14% of 120 = 0.14 *120 = 16.8

14% of 120 is 16.8. Explanation: to get 10% of 120, simply move the decimal one place to the left. Getting 10% of something is the same as dividing it by 10 (120 divided by 10 is 12.). Now, to find 4% of 120, multiply 0.4 x 12 and you get 4.8. This is a hack to finding out percentages, simply take every number in 120 except for the last one, which is 0. That makes it 12. In order to make it balanced, we have to preform the same effect on 4, making it 0.4. (Oml this doesn’t make sense does it-) Example: to find 40 percent of 60, take every digit in those two number except for the last one, so 4 and 6. Then proceed to multiply them. If there is a one digit number, move the decimal one place to the left. I hope this math hack helps you in the future. Anyways, continuing. Now that we figured out 10% and 4% of 120, all that is left to do is add. 4.8 + 12 = 16.8. That is why 16.8 is the answer. (Kavlgdmgakgskgs this is way too long I hope I didn’t blabber on too much)

Answers

Answer:

0; (0, 0); 144; (3, 144)

Step-by-step explanation:

Y = distance (m)

X = time (hr)

X = 48x

If a car travels for 0 hours, it will travel __ mile(s).

y = 48x

Plug in 0 hours for x (time in hours)

y = 48(0)

Any number mutliplied by 0 equals 0

y = 0

If a car travels for 0 hours, it will travel 0 miles. This means it will pass through the point (0, 0).

(0, 0) limits our options to graphs B and D

Car travels 144 miles in 3 hours

To find how many miles it travels in 1 hour, divide 144 miles by 3 hours

144 ÷ 3 = 48

In 1 hour, a car travels 48 miles

If 48 × 3 = 144, then 48 × 4 = ?

48 × 4 = 192

When looking at graph D, there are 4 lines above 0

Counting by 48, it perfectly fits 192 by the fourth line

From (0, 0), if we move 3 units to the right we can find the third vertical line intersecting

Since the lines are counted by 48 and we are looking at the third line: 48 × 3 = 144

Use the slope to move 3 units to the right of the origin and 144 unit(s) up to the find the point (3, 144) that can be used to graph the relationship

Answer:

Step-by-step explanation: 2 plus 5

7 <50

Answer:

x = 22.5

Step-by-step explanation:

2x + 5 > 50.

We do inverse operations sooo:

2x + 5 - 5 > 50 - 5.

50 - 5 = 45.

Then we do 2x ÷ 2 and 45 ÷ 2.

45 ÷ 2 = 22.5.

To check our answer to see if its right we do 22.5 x 2 which equals 45. Then we do 45 + 5 which equals 50. So the sign is wrong it should be greater than or equal to.

A circle has a diameter of 20 ft. What is the diameter? *

Answers

Since the question provided the diameter instead of radius, the diameter is 20 feet

Answer: well the diameter would be 20ft. If you meant to ask for the circumference then its 62.857ft

Step-by-step explanation:

Diameter of a circle is 20​ feet.

Hence it's Radius = 20/2 = 10 ft

We know circumference = 2πr

Circumference = 2 × 22/7 × 10 ft

Circumference = 44 × 10/7= 440/7
