Select all ratios equivalent to 1:2 A. 10:20 B. 12:24 C. 8:16

Answer:Answer is 36 inches high.

Step-by-step explanation:

Each term is 3 times the number of months. So, the

expression is 3n.

3 3(12) n

Replace n with 12.

36

At the end of 12 months, the plant will be 36 inches high.

Answer: it is 0

Step-by-step explanation:

[5.5+(-2.3)] + (-5.5+2.3)

We can multiple (-5.5+2.3) by -1 so that it equals the first expression

[5.5+(-2.3)] + (-1)[5.5+(-2.3)]

Then, we change the + to -

[5.5+(-2.3)] - [5.5+(-2.3)]

since we are subtracting the same value, the answer is 0.

Answer:

A. The constant ratio of y/x is 12/5

Step-by-step explanation:

The ratio of y to x is constant which is 12/5. Hence option A is the correct option.

What is a constant?

The term "constant" has several meanings in mathematics. When used as a noun, it can have any of the following two meanings:  a constant, clearly defined number or another immutable mathematical object.

Given table is

x                 y

5/6             2

25/6          10

125/6        50

625/6      250

When x = 5/6 and y = 2:

x/y = (5/6)/2 = 5/12

∴y/x = 5/12

When x = 25/6 and y = 10:

x/y = (25/6)/10 = 25/60 = 5/12

∴y/x = 5/12

When x = 125/6 and y = 50:

x/y = (125/6)/50 = 125/300 = 5/12

∴y/x = 5/12

When x = 625/6 and y = 250:

x/y = (625/6)/250 = 625/1800 = 5/12

∴y/x = 5/12

The like terms to 4/5 in the group 2 are given as follows:

D. -0.1.

F. 12.

Like terms are terms that have the same letter and the same exponent, as thus they can be either added or subtracted to simplify expressions.

The most basic example of like terms are constants, as they can always be added or subtracted.

In group 2, the terms that are constant are the terms -0.1 and 12, hence they are like terms to the fraction 4/5, meaning that the correct options are given by options D and F.

The like terms to -2.1x would be of 3x and also x/3, as they would have the same variable x with exponent 1.

Step-by-step explanation:

"When the ratio of part to whole is equal to the ratio of a percent to 100, shows a percent equal to an equivalent ratio, we call it a percent proportion. A percentage is a fraction expressed with 100 as the denominator. When two ratios are equal, they are said to be in proportion."

When the ratio of part to whole is equivalent to the ratio of a percent to 100, shows a percent equal to an equivalent ratio, we call it a percent proportion. A percentage is a fraction expressed with 100 as the denominator. When two ratios are equal, they are said to be in proportion.

Hope this helps :)

Answer: Ratios form a proportion if they are equal when cross-multiplied.

1/4 and 3/12

Cross-multiply these ratios to compare them: 1/4 * 12 = 3, 3/12 * 4 = 3.

So they are equal and form a proportion.

54/10; 81/15

Cross-multiply these ratios to compare them: 54/10 * 15 = 81, 81/15 * 10 = 54.

So they are equal and form a proportion.

18/24; 15/20

Cross-multiply these ratios to compare them: 18/24 * 20 = 15, 15/20 * 24 = 18.

So they are equal and form a proportion.

Hence, all the ratios mentioned above form a proportion.

2. number 7. x+x+x=9 that is A. and x+3=9 for B.

3. part a: x+9=16 draw a box with x+9=16 and x=7

3. part b: 4(x)=28 draw a bout that matches that and x=7

Step-by-step explanation:

1. the value of x is seven because 5x = 35 divide x on both sides is 7

2. number 7. x+x+x=9 that is A. and x+3=9 for B.

3. part a: x+9=16 draw a box with x+9=16 and x=7

3. part b: 4(x)=28 draw a bout that matches that and x=7

Answer:

We can use the given information to set up a system of two equations:

c = 13g + 20

c - 13g = 20

The second equation is obtained from the first equation by subtracting 13g from both sides.

To solve this system, we can use substitution.

First, we solve the second equation for c.

c = 20 + 13g

Then, we substitute this expression for c into the first equation.

20 + 13g = 13g + 20

Then, we simplify.

20 = 20

So, the value of c when g = 9 is 20 + 13 * 9 = 20 + 117 = 137.

-3°

Step-by-step explanation:

The time for 22 leg-press reps is 11.9 seconds.

The lines of best fit is the trend line of the dataset.

The table is given as —

(x) : 12 32 7 26 28 15 1

(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5

To determine the equation of line of best fit, we make use of a regression calculator.

Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)

This means that x = 22.

So, we have:

y = 0.120 * 22 + 9.274

  = 2.640 + 9.274

  = 11.914

(Approximate to the nearest hundredths)

  = 11.9

Hence, the time for 22 leg-press reps is 11.9 seconds.

Answer:

#5 = option a (129.38 miles):

We are told that the cities are 17.25 inches apart, and that 2 inches equal 15 miles. First we have to divide 17.25 inches by 2 we end up with 8.62500 inches (not simplified yet). Next, we just take 8.62500 inches and multiply that with 15, which leaves us with 129.37500 inches. Then we just round that to the nearest hundredth which will give us 129.38 inches which means 129.38 miles as well!

#2 = option a (2.4 inches)

We know that bigger rectangle's length is 16 inch and that smaller rectangle's length is 3.2 inches. We just have to calculate the decrease of the length and we do that by dividing. We have to do 16 inches divided by 3.2 inches which equals 5. (You can double check that by multiplying 3.2 inches by 5 which would equal 16 inches) Now to find the width of the smaller rectangle, we just have to divide the width of the bigger rectangle, which is 12 inches, by 5 which would give us 2.4 inches!

#4 = ?

#6 = option c (7.2cm)

So basically I just did 25cm divided by 10cm which equals 2.5cm. (You can also do 25cm divided by 2.5cm to get 10cm if you want to double check). Then I just did 18cm divided by 2.5 cm which led me to the answer 7.2cm)

#3 = ?

Answer: A

Step-by-step explanation: 17.25/2=8.652

Answer:

Step 1: 4x = -16

Step 2: x = -4

Answer:

200 tickets.

Step-by-step explanation:

85% = 85/100 = 0.85

170/0.85 = 200

= 200

Check:

200*0.85 = 170

Answer: hope this helps ♡

200 tickets were originally put up for sale.

Step-by-step explanation:

85% = 170

(we divide 85 and 170 by 85)

1% = 2

(now multiply 1 and 2 by 100)

100% = 200

(double check: 85% from 200 → (85×200) ÷ 100 = 170 ✓)

Answer: 2.8, hope it helps.
