Answer:

The graph is not a function

Step-by-step explanation:

Since the vertical line will pass through more than one point, the graph passes the vertical line test. Therefore, the relation Is Not a function

Answer:

B = (A - C)/5

Step-by-step explanation:

Subtract both sides by C

A - C = 5B

Divide both sides by 5

B = (A - C)/5

Step-by-step explanation:

#1

6 × n + 15 = -42

6n + 15 = -42

6n = -42 - 15

6n = -57

n = -57/6

n = -19/3

#2

b + 3/2b + b + 45 + 2b - 5 + 90 = 540

b + 1.5b + b + 45 + 2b - 5 + 90 = 540

5.5b + 130 = 540

5.5b = 540 - 130

5.5b = 410

b = 410/5.5

b = 74.5

Angles are

b = 74.5

1.5(74.5) = 111.75

74.5 + 45 = 119.5

2(74.5) - 5 = 144

Answer:

Step-by-step explanation:

Usually, when you have a rate of the form ...

  A per B

we consider the B to be the independent variable. The value of A is then the dependent variable.

Here, you have dollars per hour, so ...

b) (-2.5)(-2.5) = 6.25 = [tex]\frac{625}{1000} = \frac{5}{8}[/tex]

Step-by-step explanation:

Answer:

a. dbc = 66, ABC = 132

b. abd = 52, dbc= 52

Step-by-step explanation:

just remember that bisects means that the angles on either side of the middle line are equal. so for a, dbc = abd and ABC = 2x 66

for b, abd and dbc are equal, so both of them are just 104 divide by two

Answer:

-1

Step-by-step explanation:

A polynomial doesn't include no negative exponents so our answer has to be negative in order to make our power positive.

This terms is in between a quadratic and constant term so the terms has to be raised to 1st power.

It has to be negative so the answer will be

Answer:

Incorrect, view explanation

Step-by-step explanation:

750t is basically 750 x t.

If t = 5 per say, this would be 750 x 5. It wouldn't take around 3,000 days to paint that fence. (probably)

We are trying to get the number of days, so lets focus at that.

If Olivia paints T planks per day , we are going to want to divide the number of planks (t), so we can get how many days it would take.

So lets set an example, t = 250, to simplify things.

750/250 = 3 days.

Therefore, 750/t is your correct answer instead.

[tex]-4\frac{14}{15}[/tex]

Step-by-step explanation:

[tex]12\frac{2}{5} -17\frac{1}{3}[/tex]

Step 1. See if both mixed fractions have the same common denominator

Answer: No.

Explanation: The first fraction [tex](12\frac{2}{5})[/tex] has a denominator of 5 and the second fraction [tex](17\frac{1}{3})[/tex] has a denominator of 3.

Step 2. so now that we know they have different common denominator, find the LCM (Least Common Denominator) for both mixed fractions.

To do this, find their LCM' (Least Common Multiple).

Answer: 30.

Explanation:

Multiples of 5:

5: 5, 10, 15, 20, 25, 30, 35, 40, 45,...

Multiples of 3:

3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30,...

Their LCM' (Least Common Multiple) is 30.

Step 3. Convert each of the mixed fractions into a common denominator of 30.

Answer:     [tex]12\frac{2}{5} =12\frac{12}{30}[/tex]       [tex]17\frac{1}{3} =17\frac{10}{30}[/tex]

Explanation:

[tex]12\frac{2}{5} =12\frac{?}{30}[/tex]                 [tex]17\frac{1}{3} =17\frac{?}{30}[/tex]

To find their numerator, think about how 5 being multiplied by a number equivalent to 30 and 3 being multiplied by a number equivalent to 30 (as well).

Step 4. Use the two mixed fractions [tex](12\frac{12}{30} -17\frac{10}{30} )[/tex] to subtract

Answer:

Explanation:

[tex]12\frac{12}{30} -17\frac{10}{30} =[/tex]

Multiply denominator by whole number and add the numerator (Keep the denominators the same)

[tex]\frac{372}{30} -\frac{520}{30} =[/tex]

Subtract

[tex]-\frac{148}{30}=[/tex]

Simplify

[tex]-4\frac{14}{15}[/tex]

Final Answer

The difference between the two given mixed fractions is -4 14/15.

The given fractions are 12 2/5 and 17 1/3.

We need to find the difference of the given fraction.

Steps to subtract mixed fractions:

Step 1– Convert the mixed numbers into improper fractions.

Step 2– Find the common multiple of both denominators.

Step 3– Convert the fractions into common denominators.

Step 4– Solve the fractions.

Now, 12 2/5 can be written as 62/5 and 17 1/3 can be written as 52/3.

Difference=62/5 - 52/3

=186/15 - 260/15

=-74/15

=-4 14/15

Therefore, the difference between the two given mixed fractions is -4 14/15.

Answer:

[tex]\frac{200}{2793}[/tex]

Step-by-step explanation:

1. Convert the decimal into a fraction by doing this. Take 1.8 and write it above a fraction line without the decimal sign.

2. Count the decimal places and below the fraction line write the multiple of 10 with that many zeros so that would [tex]\frac{18}{10}[/tex]

3. Simplify the fraction so that would be [tex]\frac{9}{5}[/tex].

4. Now in order to divide a fraction, multiply by the reciprocal of that fraction so that would be [tex]\frac{9}{5} *\frac{1000}{25137}[/tex].

5. Now reduce the number with the gcf (greatest common factor) which would be 5. So now we have 9*[tex]\frac{200}{25137}[/tex]

6. Reduce the numbers again using the gcf which now would be 9. Now you have the answer which should [tex]\frac{200}{2793}[/tex]

[tex]\\ \sf\longmapsto x=320million [/tex]

Canada has a population that is about 1/10 as large as the United States. If Canada's population is about 32 million, about how many people live in the United States? Explain the number of zeros in your the answer.

Given,

Population of Canada = 32 million (1/10 of that of the USA)

=> Let the population of the USA be 'x'.

Now,

→ x/10 + 32 (million)

→ x = 32 × 10

→ x = 320 million.

(The number of zeros in 1 million is 6, so the number of zeros in 320 million will be 7)

320000000 or 320 million.
