all three pairs of appropriate sides of a triangle are proportional, the ratio is the same.

10/5=8/4=6/3=2 so the triangles are similar

Step-by-step explanation:

150 x 60 = 9,000 every hour

9000 x 24 = 216,000 every day

216000x 365 = 78,840,000 every year

Answer:

Hour: 9,000 people

Day: 216,000 people

Year: 78,840,000 people

Step-by-step explanation:

In order to solve this, you need to identify how many minutes there are in an hour, a day, and a year:

Hour: 60 minutes

Day: 60 minutes × 24 hours = 1,440 minutes

Year: 60 minutes × 24 hours × 365 days = 525,600 minutes

Now, you need to multiply each of these numbers by 150 to find how many people are born every hour, day, and year:

Hour: 60 minutes × 150 people = 9,000 people

Day: 1,440 minutes × 150 people = 216,000 people

Year: 525,600 minutes × 150 people = 78,840,000 people

Answer:C

Step-by-step explanation:

One shirt is represented as “y”

He ordered four shirts totaling $44

y+y+y+y =$44

Answer:

1. x = 462.30m

2. c

Step-by-step explanation:

1. Let "x" represent how much Samantha earns, and "m" represent how many months she has worked.

Because she makes $462.30 per month, if we multiply that by "m" then we will get x.

2. Kyle spend $44 on four sweaters total, which would make the total cost be evenly distributed into 4 sections.  

Answer:

So i would ask this friend to draw a number line and label 6.2 on the number line. Then i would ask her if she knew what the opposite number of 6.2 is.

Yes- The number line will always continue, its indefinite. This means it can go forward or backwards. Make sure that your friend wrote 0. You always need a starting point. Then tell her to draw the tally marks forward the same way she did backwards. Locate the 6.2 and make all of the numbers negative.

The complete sentences to explain to your friend how to graph the opposite of 6.2 on the number line as shown below.

Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.

Given that;

Suppose one of your friends was absent from school on the day your math class learned about graphing rational numbers on the number line.

Hence, The complete sentences to explain to your friend how to graph the opposite of 6.2 on the number line as;

Firstly I would ask this friend to draw a number line and label 6.2 on the number line. Then I would ask her if she knew what the opposite number of 6.2 is.

Then, Make sure that your friend wrote 0. You always need a starting point. Then tell her to draw the tally marks forward the same way she did backwards. Locate the 6.2 and make all of the numbers negative.

Answer:

(1/2)x-1/2 hope this is the answer if it's not then srr

The inverse of the function is h ( x ) = (1/2)x - 1/2

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 2x + 1

The inverse of the function is calculated by taking the x coordinate and replacing it with y

So , the function now becomes

x = 2y + 1

On simplifying , we get

Subtracting 1 on both sides , we get

2y = x - 1

Divide by 2 on both sides , we get

y = ( x - 1 ) / 2

Now , replacing y with x , we get

h ( x ) = ( x - 1 ) / 2

h ( x ) = ( 1/2 )x - ( 1/2 )

Hence , the inverse of the function is h ( x ) = ( x - 1 ) / 2

Answer:

x = -1

Step-by-step explanation:

1/2 (3x +4 ) = 1/2

1/2 x 3x + 1/2 x 4 = 1/2

1.5 x + 2 = 1/2

1.5x = 1/2 -2

1.5x = -1.5

1.5x /1.5 = -1.5/1.5

x = -1

Grace got 15 x 12 = 180

Answer:

72/149

Step-by-step explanation:

Just to clarify, the curly braces mean the same thing as normal parenthesis.

(12 + 5^2) = (12 + 25) = 37

(-7-15)^2 = (-22)^2 = 484

6^3  = 216

(12 + 5^2) - (-7-15)^2 = 37 - 484 = 447

6^3 / ((12 + 5^2) - (-7 - 15)^2) = 216 / 447 = 72/149

the correct answer is 12

Step-by-step explanation:

First I set up a formula to solve how many ounces of salt there were out of 30,      

x/30=20/100, I crossed multiplied and got 5/30, next, I set up the same formula for how many ounces of salt there were out of 25, x/25=30/100, I got 7.5, the last thing I did was add them both together leading me to the answer 12.5 or 12 1/2. Hope this helps! Please say if I am wrong.
