What is 38 percent of 10 oranges

Answers

Answer:

The answer is 3.8

Explanation:

Move the decimal over once to the left.

Answer:

3.8 oranges.

Step-by-step explanation:

Step 1: Our output value is 10.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 10=100%.

Step 4: Similarly, x=38%.

Step 5: This results in a pair of simple equations:

10=100%(1).

x=38%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

10/x= 100%/38%

Step 7: Again, the reciprocal of both sides gives

x/10 = 38/100

---> x=3.8$

Therefore, 38% of 10 is 3.8

simplify the following. 368+169

Five girls in a homeroom class of 20 students have blonde hair. If there are 120 students in the school, how many would you predict are blonde haired girls?

Answers

Step-by-step explanation: To find how many girls are blonde-haired, we'll have to subtract.

120 - 20 =

1. Subtract 0 by 0.

0 - 0 = 0

2. Subtract 2 by 2.

2 - 2 = 0

3. Since there isn't a number in the hundred's place, bring the 1 down.

Therefore, your answer is: 100. There are 100 blonde-haired girls.

In one classroom their is about 25% people that are blonde, so in 6 classes with 20 people each their would be 30 blonde haired girls.

Convert these mixed numbers into improper fractions.

1 4/7

Answers

Answer:

[tex]2\frac{2}{3}[/tex] = [tex]\frac{8}{3}[/tex]

[tex]1\frac{4}{7}[/tex] = [tex]\frac{11}{7}[/tex]

Step-by-step explanation:

[tex]2\frac{2}{3}[/tex]

To convert a mixed number to an improper fraction all you need to do is......

Multiply the denominator of the fraction (3), by the whole number (the big number in front of the fraction) (2), and then you add the numerator....

Denominator times the whole number ( 3 * 2 = 6)

Now add the numerator with what you got ( 6 + 2 = 8)

Now the "8" will be the new numerator, and the denominator stays the same "3".

Improper fraction: [tex]\frac{8}{3}[/tex]

__________________________________________________________

[tex]1\frac{4}{7}[/tex]

We can do the same steps we did for the one above

Multiply the denominator (7) by the whole number (1), and then add the numerator (4)....

Denominator times whole number ( 7 * 1 = 7)

Add the numerator to the answer you got ( 7 + 4 = 11)

Now "11" will be the new numerator, and the denominator stays the same "7".

Improper fraction: [tex]\frac{11}{7}[/tex]

The linear function is represented by the equation y = -3/5x -2. What can be determined of this equation written in slope-intercept form? Check all that apply

Answers

Answer:

We can determine the slope m and the y-intercept of the linear function when the linear equation y = -3/5x -2 is written in slope-intercept form.

Thus, we concluded that:

The y-intercept b = -2The slope m = -3/5

Step-by-step explanation:

The slope-intercept form of the linear/line function

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

Given that the linear function is represented by the equation

[tex]y\:=\:-\frac{3}{5}x\:-2[/tex]

comparing with the slope-intercept form of the linear/line equation

[tex]y = mx + b[/tex]

Therefore,

The slope m = -3/5The y-intercept b = -2

Hence, we can determine the slope m and the y-intercept of the linear function when the linear equation y = -3/5x -2 is written in slope-intercept form.

Thus, we concluded that:

The y-intercept b = -2The slope m = -3/5

10.On a monday you swim 12 laps in 30 minutes. On tuesday you swim 15 laps in 45 minutes are these rates porportional? Explain.

Answers

Answer and explanation:

1. 15 girls to 6 boys = 15:6

15/6= 5/2

2. 24 players to 3 teams = 24:3

24/3= 8/1=8

3. 48 worksheets to 12 students =48:12

48/12= 4/1

4. 4/7 and 24/35 are not proportional as they do not reduce to same ratio

5. 11/12 and 33/36 are proportional because they reduce to same same ratio(33/36=11/12)

6. 8/24 and 5/15 are proportional beacaue they reduce to same ratio(8/24=5/15=1/3)

7. 3/7 and 12/21 are not proportional because they do not reduce to same ratio(3/7≠12/21)

8. 25 cars in 5 days= 25/5= 5 cars each day. 60 cars in 12 days = 60/12=5 cars each day. Therefore they are proportional.

9. 14 books in 2 boxes= 7 books per box. 20 books in 3 boxes = 20/3= 6.667. Therefore they are not proportional.

10. 12 laps in 30 minutes =12/30=2/5

15 laps in 45 minutes =15/45=1/3. Therefore they are not proportional.

A statistics student has a mean score of 92 in the first 3 tests. Suppose there are a total of 4 tests and all of them have equal weight. You can also assume that there is no extra credit in the last test. What is the best possible final average this student can get

Answers

Answer:

The best possible final average this student can get is 94.

Step-by-step explanation:

The average score is given by the sum of the scores of all tests divided by the number of tests.

In this question:

First three tests: Mean score of 92, so total score of 92*3 = 276

Best possible score, with 4 tests:

In the first three, the total is 276. The best possible score is with a grade of 100 in the fourth test. The score will be:

[tex]M = \frac{276+100}{4} = \frac{376}{4} = 94[/tex]

The best possible final average this student can get is 94.
