Two cars started to move towards each other at the same time. The speed of the first car was twice the speed of the second car. They met in 2 hours. If the distance traveled altogether was 300 km, find the rates of the cars.

Answers

Answer 1

Answer:

(x + 2 x) * t = 300 km

3x = 300 km/ 2 hrs = 150 km / hr

x = 50 km / hr

One car traveled at 50 km / hr and the other at 100 km / hr

In 2 hours they traveled 300 km

Answer 2

The speed of the first car is 100 km/hr and that of the second car is 50 km/hr.

What are work and time?

Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.

Another illustration of labor is when you finish your meal in an hour, which means that you finished your work in an hour. In essence, work is the length of time it took you to complete any task.

Speed of the second car is = v

The speed of the first car = 2v

Given that

Distance covered by = 300 km

Time taken = 2 hr

By relative velocity concept

2v + v = 300/2

3v = 150

v = 50 km/hr.

Hence the speed of the first car will be 100 km/hr and that of the second car will be 50 km/hr.

Step-by-step explanation:

I hope I helped you^_^

Answer:

a = 53

Step-by-step explanation:

This is a 45- 45- 90 triangle with sides in the ratio x : x : x[tex]\sqrt{2}[/tex]

x are the legs and x[tex]\sqrt{2}[/tex] the hypotenuse

Here x[tex]\sqrt{2}[/tex] = 53[tex]\sqrt{2}[/tex] , then x = 53

That is the leg a = 53

P varies directly with T and p=10 when T=500. When T=509, find T

Answers

Answer:

Let,

P= kT

P = 10, when T = 500

So, 10=k500

or, k=10/500

or, k=1/50

When T=509

P=kT

or, P=(1/50)×509

or, P=508/50

or, P = 10.18

And when P = 509 (since the question isn't clear)

509=(1/50)×T

or, T=509×50

or, T=25450

solve n

7

Answers

Answer:

see below

Step-by-step explanation:

b - 4 = 3

Add 4 to each side

b - 4+4 = 3+4

b = 7

-32 = 8w

Divide by 8

-32/8 = 8w/8

-4 = w

n/7 = -4

Multiply by 7 to each side

n/7 *7 = -4*7

n = -28

Answer:

1. b = 7

2. w = -4

3. n = -28

Step-by-step explanation:

1. b - 4 = 3

Tip: Whenever there’s a number being subtracted or added, it’s best to make that number a 0

Step 1. Add 4 to both sides

b - 4 = 3

b + 4 = +4

b = 7

—————————————
2. -32 = 8w

Step 1. Isolate the variable
(by dividing both sides by 8)

w = -32/8

w = -4

—————————————
3. n/7 = -4

Step 1. Multiply 7 x -4

n = -28

[tex]-73[/tex]

Step-by-step explanation:

Note: My explanation is based of the order-of-operations

First, using the order-of-operations, we evaluate the expressions in parentheses. Fully simplifying [tex](5-7)^2[/tex] gives us: [tex](5-7)^2 = -2^2 = 4[/tex].

Next, we do [tex]6\cdot2[/tex] giving us [tex]12[/tex]. So far, our expression is simplified to [tex]\frac{84}{12} + 4 - 72 - 12[/tex].

We also know that [tex]\frac{84}{12}[/tex] is just [tex]7[/tex] so we can replace that value in the expression leaving us with: [tex]7+4-72-12[/tex]. Now, we can solve it in simple steps!

1)  [tex]7+4=11[/tex]

3) [tex]11-72=-61[/tex]

4) [tex]-61-12=-73[/tex]

Our answer is [tex]-73[/tex]

What is the volume of a cylinder, in cubic centimeters, with a height of 8 centimeters
and a base diameter of 16 centimeters? Round to the nearest tenths place

Answers

Answer:

1608.5 cm³

Step-by-step explanation:

Use the cylinder volume formula, V = [tex]\pi[/tex]r²h

If the diameter is 16 cm, then the radius is 8 cm.

Plug in the radius and height into the formula, and solve:

V = [tex]\pi[/tex]r²h

V = [tex]\pi[/tex](8)²(8)

V = [tex]\pi[/tex](64)(8)

V = 1608.5

So, to the nearest tenth, the volume of the cylinder is 1608.5 cm³

Answer:

Answers

Answer:

29 degrees

Step-by-step explanation:

If I read your question correctly, your degree measures were

35, 52, and 3(x+2).

We know that all triangle angles measure up to 180 degrees, so we can add all of the given degree values to 180.

35+52+3(x+2)=180

Now, we can solve for x.

87+3x+6=180

93+3x=180

3x=87

x=29

Rick used a stick to trace a large rectangle in a sandy lot
near his house. The rectangle measures 13 feet by 15
feet. What is the perimeter of the rectangle?

Answers

Answer:

56 feet

Step-by-step explanation:

Perimeter is what the sum of all sides lengths of a polygon is. So if the retangle measures 13x15 feet, the perimeter would be 13+13+15+15. Because the 13x15 is only two sides, and a retangle has 4 sides. So we need to incorperate the other two sides, which are the same as the others because it is a retangle.

Round 71.916476787 to 1 decimal place.

Answers

Answer:

71.9

Step-by-step explanation:

Whenever you want to round a number to a particular digit, look only at the digit immediately to its right. For example, if you want to round to the nearest tenth, look to the right of the tenths place: This would be the hundredths place digit. Then, if it is 5 or higher, you get to add one to the tenths digit.

After rounding 71.916476787 to 1 decimal place we get 71.9.

What is rounding of numbers ?

We round numbers to get an approximate value of the given number in more compact form and which is easy to work with.

According to the given question we have to round 71.916476787  to 1 decimal place.

So, to round 71.916476787 to 1 decimal place we'll look at the digit of 2 decimal place here in this number it is 1 hence it is less than 5 so we can make all the digits after 1 decimal places zero and rewrite this number as

71.900000000 and we know zeroes are meaning less to the right of the decimal so this can be written as 71.9.
