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

Answer:

Answer:

A

Step-by-step explanation:

The domain is the set of possible x values.

The given x-coordinates are -2, 1, 0, 3

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

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.

Answer:

  x = 6

Step-by-step explanation:

If we assume that ray VA is between VW and VU, then we have ...

  ∠WVA + ∠AVU = ∠WVU

  106° +(4x +4)° = (21x +8)°

  102 = 17x . . . . . . . . . . . . . subtract 4x+8

  6 = x . . . . . . . . . . divide by 17

Answer:

Step-by-step explanation:

40% is ur answer

Answer:

The value of (2x+y) is 3.

Step-by-step explanation:

First, we have to find the values of x and y.

We have that:

x + 2y = 9, which also means that:

x = 9 - 2y

Replacing into the second equation, to find y:

[tex]3x - y = -8[/tex]

[tex]3(9 - 2y) - y = -8[/tex]

[tex]27 - 6y - y = -8[/tex]

[tex]7y = 35[/tex]

[tex]y = \frac{35}{7}[/tex]

[tex]y = 5[/tex]

Finding x:

[tex]x = 9 - 2y = 9 - 10 = -1[/tex]

What is the value of (2x+y)?

2(-1) + 5 = -2 + 5 = 3

The value of (2x+y) is 3.

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.

Step-by-step explanation:

Answer:

42

Step-by-step explanation:

p - 13 = 29

Add 13 to both sides.

p - 13 + 13 = 29 + 13

p = 42

Answer:

p= 42

Step-by-step explanation:

29 plus 13 equals 42 which leaves p alone so p equals 42

Answer:

3/28

Step-by-step explanation:

There are 14 marbles in the bag.  So, the probability of choosing a blue marble is 7/14 or 1/2.  Since the first marble is replaced, the  bag still has 14 marbles in it.  Then the  probability of choosing a red marble is 3/14.  The probability of choosing the blue, then the red is 1/2 x 3/14 = 3/28

Answer:

B. 2

Step-by-step explanation:

Based on the Midsegment of a trapezoid theorem:

GH = (BC + FE)/2

9x - 3 = (19 + (5x + 1))/2) (substitution)

9x - 3 = (20 + 5x)/2

Cross multiply

2(9x - 3) = 20 + 5x

18x - 6 = 20 + 5x

Collect like terms

18x - 5x = 20 + 6

13x = 26

Divide both sides by 13

x = 26/13

x = 2

Answer:

It is side angle side

Step-by-step explanation:

The two sides of the triangle are around the angle

The similarity theorem that identifies the given relationship correctly would be:

B). AABC - ADEF by SAS Similarity Theorem

The SAS similarity Theorem state that in the situation where the ratio shared by the sides of two triangles remains the same and one of their angles stays equal, both the triangles would be similar.

In the given two triangles,

ΔABC and ΔDEF

The ratio of the sides are:

[tex]\frac{BC}{AB} = \frac{EF}{DE}[/tex]

so,

[tex]\frac{5}{15} = \frac{4}{12} = \frac{1}{3}[/tex]

and,

∠B = ∠E = 86°

Since the ratios shared by the two sides are equal in both the given triangles and one angle is equal, the triangles are the same.

Thus,

ΔABC ~ ΔDEF
