Indicate below whether the equation in the box is true or false 4/10=1/2

Answers

Answer:

False

Step-by-step explanation:

4/10's numerator (top number) and denominator (bottom number) can both be divided by 2. Therefore, when we do that, it will be equal to 2/5. 2/5 is not equal to 1/2. Therefore, the answer is false.

Angle a and b are supplementary angles, and a is x-3 and b is x+14 what are the measures of angle a and b

Answers

Answer:

a = 81.5

b = 98.5

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

a = x-3

b = x+14

In supplementary angles , the formula are as follows,

a + b = 180

By putting the value, we get

x - 3 + x + 14 = 180

2x + 11 = 180

2x = 180 - 11

2x = 169

x = 169 ÷ 2

x = 84.5

So, a = 84.5 - 3

= 81.5

b = 84.5 + 14

= 98.5

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

here, we have,

Given:

Luisa Díaz drove her vehicle about 7,200 miles last year.

Total fixed cost = $1,058.40

Total variable cost = $1965.60

Question asked:

How much did it cost per mile ?

Solution:

Total cost of driving 7200 miles = Total fixed cost + Total variable cost

                                                    = $1,058.40 + $1965.60

                                                    = $3024

By unitary method:

Cost of driving 7200 miles = $3024

Cost of driving 1 mile = $3024  7200

                                  = $0.42

Thus, cost of driving per mile is $0.42

Answers

Answer:

[tex]Volume = 2 + 3+6[/tex]

Step-by-step explanation:

Given

[tex]Length = 2[/tex]

[tex]Width = 3[/tex]

[tex]Height = 6[/tex]

See attachment for box

Required

Which does not represent volume?

The volume is calculated as:

[tex]Volume = Length * Width * Height[/tex]

This gives:

[tex]Volume = 2 * 3 * 6[/tex] ---- (b) represents volume

Multiply 2 and 3

[tex]Volume = 6 * 6[/tex] ---- (d) represents volume

The above product can be converted to addition, as:

[tex]Volume = 6 + 6 + 6 + 6 + 6 + 6[/tex] ---- (a) represents volume

Hence:

[tex]Volume = 2 + 3+6[/tex] --- does npot represent volume

Step-by-step explanation:

Given

The lock has 3 dials, each with the number 0 through 9.

The first place can be filled in 10 ways and the probability of selecting number '4' out of the 10 is  [tex]\frac{1}{10}[/tex]

Similarly for selecting '3' and '9' is also [tex]\frac{1}{10}[/tex]

Therefore the probability of getting a combination of 4-3-9 is

[tex]\Rightarrow P=\dfrac{1}{10}\times \dfrac{1}{10}\times\dfrac{1}{10}\\\\\Rightarrow P=\dfrac{1}{1000}\\\\\Rightarrow P=0.001[/tex]

Q7.
There are 15 children at a birthday party.
The mean age of the 15 children is 7 years.
9 of the 15 children are boys.
The mean age of the boys is 5 years.
Work out the mean age of the girls.

Answers

Answer:

10

Step-by-step explanation:

Let c = sum of ages of all children.

mean age of all children = c/15 = 7

c = 15 * 7 = 105

The sum of the ages of all children is 105.

Let b = sum of ages of the 9 boys.

mean age of boys = b/9 = 5

b = 9 * 5 = 45

The sum of the ages of the boys is 45.

The sum of the ages of the girls is c - b.

c - b = 105 - 45 = 60

The number of girls is 15 - 9 = 6

mean age of girls = (sum of ages of the girls)/(number of girls) =

= 60/6 = 10

Word problems can be tricky no matter what level of math or science you are in.

First look at the question for words that indicate mathematical symbols.

"times" indicates multiplication

"and" indicates addition

"a number" means we have a variable, x, to solve for

Now we can go from left to right and write it in a mathematical equation

7x + 7 = 6x

Then, solve for x

7x + 7 = 6x

7 = 6x - 7x

7 = -1x

7/-1 = x

x = -7

Finally, we check our work.

7x + 7 = 6x

7(-7) + 7 = 6(-7)

-49 + 7 = -42

-42 = -42 √

The answer is x = -7

1) In a school of 3600 students, number of boys is twice the number of girls. Find the number of girls.

Answers

Answer: 1200

Step-by-step explanation:

x is the number of boy

The number of boys is twice the number of girls: [tex]\frac{1}{2} x[/tex]

Total is 3600 students: x + [tex]\frac{1}{2}x[/tex]= 3600 → x = 2400

Therefore, the number of girls is: 2400/2= 1200

Answer: There are 2400 boys and 1200 girls

Step-by-step explanation:

x represents girls

2x represents boys

________________________

x+2x=3600

3x =3600

x=3600/3

x =1200

Number of girls = 1200

1200 * 2 = 2400
