Step-by-step explanation:

The number is in the form of:

This is divisible by 2, can be divisible by 3 but not divisible by 4 as 74 is not divisible by 4.

So possible number of integers is 2 or 3.

The numbers are x - 1, x and x + 1

Answer:

15) 104 lbs

16) 263 miles

Step-by-step explanation:

15)  

4/7 of their weight (182) = the water weight

4/7 × 182 = 104 lbs

16)

3.5 months = 920 miles

1 month = 920 ÷ 3.5

= 262.8571429 ≈ 263 miles

Answer:

15) 104 lb

16) 262 6/7 miles/month

Step-by-step explanation:

15)

4/7 * 182 lb = 4/7 * 182/1 lb = (4 * 182)/(7 * 1) lb = (4 * 7 * 26)/7 lb = 104 lb

Answer: 104 lb

16)

(920 miles)/(3 1/2 months) = (920 miles)/(7/2 months) =

= 920/1 miles * 2/(7 months) = (920 * 2 miles)/(7 months) =

= 1840/7 miles/month = 262 6/7 miles/month

Answer:

-4

Step-by-step explanation:

1/2 of -12 is -6. 1/2 of 4 is 2.

-6 + 2 is -4.

Answer: y = x + 1

Step-by-step explanation:

y = 1x + c

-7 = 1(-8) + c

-7 = -8 + c

-7 + 8 = c

1 = c

y = 1x + 1 or

y = x + 1

Answer:

y+8=m(x+7)

Answer:

[tex]\frac{1}{14}[/tex]

Step-by-step explanation:

[tex]\frac{1}{4} + \frac{23}{28} - 1 = ?[/tex]

First off, let's change everything to a common denominator. This will allow us to add the fractions!

To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.

Let's change the first fraction into a number with a denominator of 28!

[tex]\frac{1}{4} * \frac{7}{7} = \frac{7}{28}[/tex]

[tex]\frac{7}{7}[/tex] = 1. Multiplying a number by one doesn't change its value.

The second fraction, [tex]\frac{23}{28}[/tex], already has a denominator of 28, so we don't have to do anything with it.

Now to the third number, -1:

[tex]-1 = -\frac{1}{1} * \frac{28}{28} = -\frac{28}{28}[/tex]

Now, let's add them all up!

[tex]\frac{7}{28} + \frac{23}{28} - \frac{28}{28} = \frac{7 + 23 - 28}{28} = \frac{2}{28}[/tex]

One last step, to simplify:

[tex]\frac{2}{28} = \frac{1}{14}[/tex]

200 times / 3 minutes = x times / 60 minutes

3x = 12000

x = 4000 times in an hour

A person's heart will beat 4000 times in an hour.

Hope this helps!! :)

Answer:  4000 beats per hour

Step-by-step explanation:

200 beats     X   60 minutes    

3 minutes               1 hour

The term 'minutes' cancel out therefore you are left with beats per hour

200 x 60       =    12000    =  4000 beats per hour

The expression for the total cost will be y = 80 + 60x.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a plumber has a fixed call-out rate of $80 and an hourly rate of $60.

The expression will be formed by assuming the hourly rate to be x dollars. The expression will be written as below:-

y = 80 + 60x

Here y is the total cost 80 is the fixed cost and x is the hourly rate.

Therefore, the expression for the total cost will be y = 80 + 60x.

The complete question is given below:-

Answer:

A. reflection across the y-axiss

Step-by-step explanation:

Given:

The locations of the two points are (-4 , 8) and (-4 , -8).

To find:

The relation between two points.

From the given points (-4, 8) and (-4 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.

If a figure is reflected across the y-axis, then we change the sign of x-coordinate and the y-coordinates remain same, i.e.,

[tex](x,y)[/tex]→[tex](-x,y)[/tex]

For (-4,8)

[tex](-4,8)[/tex]→ [tex](-4,-8)[/tex]

So, it is reflection across the y-axis.

Therefore, the correct option is A.

Answer:

-96 cents

Step-by-step explanation:

(Conjectured Problem) In a state's Pick 3 lottery game, you pay $1.35 to select a sequence of three digits (from 0 to 9), such as 966. If you select the same sequence of three digits that are drawn, you win and collect $394.46.  That is your expected win?  

Expected Win =

(Probability you match the drawn sequence)(Amount won if there is a match) - (Amount you pay) =

(1/10)(1/10)(1/10)(394.46) - 1.35 =  

0.39446 - 1.35 =

-0.95554 =

-96 cents, rounded to the nearest cent

Step-by-step explanation:

Approach: If four numbers a, b, c and d are in proportion then a:b = c:d. The solution is to sort the four numbers and pair up the first 2 together and the last 2 together and check their ratios this is because, in order for them to be in proportion, the product of means has to be equal to the product of extremes.

Answer:

163.25

Step-by-step explanation:

38.50x3.5= 134.75

134.75+28.50= 163.25

38.5 per hour which explains 38.5x3.5= 134.75

28.50 is a one time fee so you add that to the total of hours 134.75+ 28.50= 163.25 in total.
