Answer:

6m

Step-by-step explanation:

Combining like terms, we have

Answer:

39.5

Step-by-step explanation:

Open the bracket by multiplying the numbers in the bracket by 2

2x-20=59

collect like terms(-20 crossing over the equal sign will become +20

2x=59+20

2x=79

Divide both sides by 2

Answer:

t = [tex]\sqrt{63} \\[/tex] or 7.94

Step-by-step explanation:

Yes, you have to use the Pythagorean theorem

A^2+B^2=C^2

So, A=9, B=t, C=12

9^2+t^2=12^2

81+t^2=144

-81        -81

t^2 = 63

t = [tex]\sqrt{63} \\[/tex]

in decimal 7.94

Hope this helps :)

1. Observe problem

Solve for the area and Circumference of a circle who's radius is 3 cm

Area for circle formula:

pi*r^2=

9pi

I simplicity is needed, 9 pi is around

28.2743338823cm^2

Circumference for circle formula: 2*pi*r

which is

6pi

if simplicity is again needed, its around

Answer:

36

Step-by-step explanation:

x = 9 and y = 3

3 times 3 equal 9 so if y is 12 then 12 x 3 = 36

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:

Rational

Step-by-step explanation:

[tex]\sqrt[3]{125}[/tex] is also equivalent to 5

The definition of a rational number is any whole number, fraction, or decimal that ends or repeats, while an irrational number is any number that cannot be turned into a fraction.

5 is a whole number, and therefore, is a rational number.

Answer:

rational

hope it helps you

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:

Approximately Normal

Step-by-step explanation:

The sample size is large (n50≥30n), so the sampling distribution of the sample mean will be approximately normal even though the population is skewed.

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:

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

Answer:

3.4h-2.7d-16

Step-by-step explanation:

Before we even start, we can already simplify some things

For example, in this equation it says +(-7.7d)

We can simplify this to 6h-7.7d-16+5d-2.6h

Now we have to get all of the common variables together

So the d’s and h’s have to be combined together in this equation

This makes a new equation of 3.4h-2.7d-16

That is our answer!

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.
