Answer:

0.625 tons or 5/8 tons

Step-by-step explanation:

(5/2)/4

0.625 tons or 5/8

Answer:

  5/8 ton

Step-by-step explanation:

1/4 of 5/2 ton is on each tire, so the weight it is bearing is ...

  (1/4)(5/2 ton) = 5/8 ton

Each tire is bearing 5/8 ton.

_____

Additional comment

If that is a US short ton (2000 lb), then the weight on each tire is 1250 pounds. If the tires are inflated to 50 pounds per square inch, then the area of rubber on the road at each tire is 1250 lb/(50 lb/in^2) = 25 in^2. That's the size of a 5-inch square.

Answer:

She can run 3 miles in her time limit.

Step-by-step explanation:

Suzie is going to run for 32 minutes. She run 1 mile in 5 minutes and she cools off for 7 minutes

5+7=12 minutes

she runs 1 mile needs 12 minutes total

32÷12=2⋯8

8-5=3 minutes

2+1=3      3×1=3 miles

She can run 3 miles in her time limit.

Answer:

KL // MN & KN // LM

Step-by-step explanation:

One property of parallelogram is every two opposite sides are parallel to each other and if a two lines (sides) are parallel so they must have the same slope.

In the parallelogram KLMN:

using the slope formula = y2-y1/x2-x1

plug the numbers: KL // MN & KN // LM so KLMN is a parallelogram

The survey is an illustration of expected value

132 people in the survey were in the 21 - 30 year old group

From the complete question, 22% of people are in the 21 - 30 year old group

Given that 600 people were surveyed.

The number of people in the 21 - 30 year old group would be:

n = 22% * 600

This gives

n = 132

Hence, 132 people in the survey were in the 21 - 30 year old group

Answer:

12/3 which is =4

Step-by-step explanation:

for adding fractions you keep the denominator the same and just add or subtract the numerators

2+11-1=12

Answer:

Step-by-step explanation:

Your first step is to figure out which variable you want to cancel out.

Luckily, all these problems have x or y already set up to eliminate.

You can find these variables because they are opposite signs of each other, such as -x and x

Add the y's together and the #'s on the other side together, then solve to find the 2nd variable. Once you find one, you can plug that answer into the easier of the two equations and solve for the other variable.

Answer:

x=70°

Step-by-step explanation:

y=350° (angle inside triangle equal to 35°)

x=180-y-(180-105)

x=70°

Hope it helps!

Solution:

We can see that two lines are parallel, intersecting a line. We can also see a triangle formed with the lines.

The measure of x is 70°.

9y-18 9y-18 9y-18

9y-18 9y-18 9y-18

Step-by-step explanation:

Given - 10 - 11i

1st requirement - conjugate

Z = X + Yi

Change the sign between x & yi to find the conjugate of a complex

number.

Z = 10 + 11i

Now multiply the conjugate & the 1st complex number

=10-11i × 10+11i

= (10 × 10)+ (10× 11i)+ (-11i × 10) + (-11i × 11i)

Recall that i = √-1

= 100 + 110i - 110i + (-(-(11 × 11))...since √-1 × √-1 = -1.

= 100 + 121

= 221.

Answer:

x -intercept is 4

y -intercept is -2

Step-by-step explanation:

SOLUTION:

(x -intercept)

-4x+8y= -16

-4x+8×0= -16

-4x+0= -16

-4x/-4 = -16/-4 (divide both sides by -4)

x=4

______________________

(y -intercept)

-4x+8y= -16

-4×0+8y= -16

0+8y= -16

8y/8 = -16/8 (divide both sides by 8)

y= -2

2 quarters, 3 dimes, 3 nickels, and 5 pennies equals

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is essential to determine the quantity of any object

1 dollar = 4 quarters

1 dollar = 10 dimes

1 dollar = 20 nickels

1 dollar = 100 pennies

We have to calculate the total dollar measurement of 2 quarters, 3 dimes, 3 nickels, and 5 pennies.

4 quarters = 1 dollar

2 quarters = 2/4 dollars

                 = 0.5 dollars

10 dimes = 1 dollar

3 dimes = 3/10 dollar

              = 0.3 dollar

20 nickels = 1 dollar

3 nickels = 3/20 dollar

               = 0.15 dollar

100 pennies = 1 dollar

5 pennies = 5/100 dollar

                  = 0.05 dollar

Total currency value = 0.5 dollars + 0.3 dollar + 0.15 dollar + 0.05 dollar

                                   = 1 dollar

Hence the total worth of coins given is 1 dollar.

Answer:

x = 56/3

PS = 103/3

Step-by-step explanation:

Perimeter:  (4x + 1) + 2(2x - 3) + (4 + 4 + 4x + 1) = 228

Collect and combine like terms:  12x + 4 = 228

Subtract 4 from both sides:  12x = 224

Divide both sides by 12:  x = 56/3

PS = (2 x 56/3) - 3 = 103/3
