Answer:

5/26+7/13

5/26+14/26

19/26

The probability that a student chosen from the class at random has either brown hair or ginger hair is 19/26.

Given that, the probability that a student chosen at random from a class has brown hair is 7/13 and the probability that they have ginger hair is 5/26.

Probability that student have either brown hair or ginger hair

= 7/13 + 5/26

= 14/26 + 5/26

= (14+5)/26

= 19/26

Therefore, the probability that a student chosen from the class at random has either brown hair or ginger hair is 19/26.

Answer:

To make an improper fraction into a mixed fraction:

1. Divide the numerator by the denominator

2. Write down the whole number answer

3. Then write down any remainder above the denominator

Example:

Turn 8/3 into a mixed fraction.

8 ÷ 3 = 2 R2

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

To make a mixed fraction into an improper fraction:

1. Multiply the whole number part by the fraction's denominator.

2. Add that to the numerator.

3. Then write the result on top of the denominator.

Example:

Turn 4[tex]\frac{6}{7}[/tex] into an improper fraction.

4 x 7 = 28

28 + 6 = 34

So... [tex]\frac{34}{7}[/tex]

Answer:

A. 8 gallons

B. Drive by car is $59.4 cheaper than travel by train

Step-by-step explanation:

According to the scenario, given data are as follows,

Total drive = 400 miles

Total drive per gallon = 50 miles

Fuel cost per gallon = $4.45

A. So, Total fuel required to drive 400 miles can be calculated as follows,

Total fuel required =  Total drive ÷ Total drive per gallon

By putting value, we get,

Total fuel required = 400 ÷ 50

= 8 gallons

B. Total cost if drive by car = 8 gallons × $4.45 = $35.6

Cost if travel by train = $95

Hence it is clearly shows that drive by car is much cheaper than travel by train.

Cost saved by travel by car = $95 - $35.6 = $59.4

So, drive by car is $59.4 cheaper than travel by train.

Answer:

Step-by-step explanation:

..

The value of x in the given figure is 93 degrees.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Let us find the interior angle of the triangle SQR.

By angle sum property the sum of three angles is 180 degrees.

35+58+x=180

93+x=180

Subtract 93 from both sides

x=180-93

x=87 degrees

Now let us find the x degrees.

The sum of interior angle of vertex Q and exterior angle is 180 degrees

87+x=180

x=180-87

x=93 degrees

Hence, the value of x in the given figure is 93 degrees.

Answer:

m=22

Step-by-step explanation:

The angles of the triangle will be equal to 180.

m + 5m + m+26 = 180

Combine like terms

7m+26=180

Subtract 26 on both sides

7m=154

Divide by 7

m=22

Answer:

m=22

Step-by-step explanation:

Triangle has 180 degrees in total

m+5m+(m+26)=180

solve

6m+m+26=180

7m=180-26

7m=154

m=22
