Answer:

1. 1/2

2. 3/4

3. 1/6

4. 1/4

5. 7/4

6. 3/2

7. 5/1

8. 2/7

9. 1/4

Step-by-step explanation:

A ratio compares values.

So if there are 3 oranges and 12 apples, we can say that there is a ratio of 3 : 12 meaning there are 3 oranges for every 12 apples.

Ratios can be written in different ways, but they mean the same thing:

  • Using the ":" to separate the values:                     3 : 12
  • Or using the word "to" to separate the values:   3 to 12
  • or as a fraction:                                                          \frac{3}{12}

A ratio can also be scaled up or scaled down (as long as we do the same thing to both values):

  • 3 : 12  is the same as 6 : 24  (multiplied both values by 2)
  • 3 : 12  is the same as 1 : 4  (divided both values by 3)

1.  2 to 4  = 2 : 4 = 2/4

We can reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 2:  2/4 = 1/2

2. 15/20

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 5:

15/20 = 3/4

3. 6 : 18 = 6/18

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 6:

6/18 = 1/6

4. 3 to 12 = 3 : 12 = 3/12

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 3:

3/12 = 1/4

5. 7 : 4 = 7/4

This fraction cannot be reduced any further as the numerator is a prime number.  Prime numbers are whole number greater than 1 that cannot be made by multiplying other whole numbers.

6. 18/12

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 6:

18/12 = 3/2

7. 35 : 7 = 35/7

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 7:

35/7 = 5/1  

(5/1 = 5 however the question is asking you to write the ratio in the lowest fraction, so the lowest fraction is 5/1)

8. 8/28

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 4:

8/28 = 2/7

9. 24 : 96 = 24/96

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 24:

24/96 = 1/4

Dr. Don offers a tutoring service for college students. He charges $40 as a fixed rate for the first hour plus $20 for each addi
AlekseyPX

Answer: 6  ≤ h ≤ 9

Step-by-step explanation:

Hi, since He charges $40 as a fixed rate for the first hour plus $20 for each additional hour, the cost of the tutoring service is equal to the fixed rate(40) plus, the product of the additional hours (h-1) and the cost per additional hour (20).

40+20(h-1)

40+20h-20

20+20h

Since a student can spend between $140 and $200, the previous expression must be greater o equal than 140, and less or equal than 200.

140≤20+20h≤200

Subtracting 20

140-20 ≤20-20+20h ≤200-20

120 ≤ 20h ≤ 180

Dividing by 20

120/20 ≤ 20h/20 ≤ 180/20

6 ≤ h ≤ 9

Estimate the answer to<br> 64 x 186<br> 21 x 98
Vikentia [17]

Answer:

I am a bit confused on what the question is asking. But 64*186= 11904 and if we were to round that number it would be 12000. 21*98=2058 and that number rounded is 2100 or just 2000. (hope this is right and helps :D)

What is 3 7/8 + 2 5/6 =​
BARSIC [14]

Answer:

$\frac{161}{24}=6\frac{17}{24}$

Step-by-step explanation:

$3\frac{7}{8}+2\frac{5}{6}$

Convert the mixed fractions to improper fractions:

$\frac{31}{8}+\frac{17}{6}$

Find the common denominator and write equivalent fractions:

$(\frac{31}{8}\times{\frac{3}{3}})+(\frac{17}{6}\times{\frac{4}{4}})$

$\frac{93}{24}+\frac{68}{24}$

Add:

$\frac{93}{24}+\frac{68}{24}=\frac{161}{24}$

Reduce to mixed fraction:

$\frac{161}{24}=6\frac{17}{24}$

Julie wanted to earn money to attend a basketball camp. She started with a gift of money from her grandparents and then saved $2
adoni [48]
The equation would be y = 25x + 50

In order to find this equation, we need to know how much the gift from her grandparents was. To do so, we have to find out how much she's saved from dog walking. 

Since she saves $25 a month for 7 months, we can find the total amount as:

25*7 = 175

Then we can subtract that from the total she has saved to find the amount for the gift.

225 - 175 = 50

Finally, we put the amount per month in the equation with the gift as the y intercept to create the equation above.

  b)  (d) The angle at the circumference in a semicircle is a right angle

Step-by-step explanation:

An inscribed angle has half the measure of the arc it subtends.

__

Angle ABC is inscribed in a semicircle and subtends an arc of 180°, so has a measure of 180°/2 = 90°. Here, that observation is described by ...
