Given : The whole number is 5.
Explanation
We use the whole number 5.
The additive inverse of 'a' is -a
a+(-a)=0
For the whole number 5, the additive inverse of 5 is -5
Multiplicative inverse of 'a' is [tex]\frac{1}{a}[/tex]
because [tex]a \cdot \frac{1}{a}=1[/tex]
So the multiplicative inverse of 5 is [tex]\frac{1}{5}[/tex]

What is the slope of the line containing (–1, 8) and (3, –12)? A. 5 B. – C. –5 D.
Answer:
-5
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
=(-12 -8)/(3 - -1)
=(-12-8)/(3+1)
= -20/4
= -5

Step-by-step explanation:
First you divide the number of clicks by seconds.
36÷5=7.2
26÷3=8.6
Now you know how much clicks the bots do in 1 second
Bot#3= 7.2
Bot#4= 8.6
Now multiply by 10.
Bot#3= 72
Bot#4= 86
Bot#4 does more clicks in 10 seconds.

what does PQ=?
what does QR=?
Answer:
PQ=12
QR= 8
Hope it helps.
Answer: PQ = 12
QR = 8
Step-by-step explanation:
3x + 6 + 2x+4 = 20
5x = 20- 10
so, x = 2
so
PQ = 3x + 6 = 3*2+6 = 6+6 = 12
QR = 2x+4 = 2*2+4 = 4+4 = 8
f(x) = -4x2 + 19

What is simplification of an equation?Simplification of an equation is the process of writing an equation in the most efficient and compact form without affecting the value of the original equation. It involves, multiply out the brackets and then simplify the resulting equation by collecting the like terms.
For the given situation,
The equation is
[tex]7x^{6}=2[{45-3(7x^{2} -15+6)}+4][/tex]
⇒ [tex]7x^{6}=2[{45-3(7x^{2} -9)}+4][/tex]
⇒ [tex]7x^{6}=2[{45-21x^{2} +27}+4][/tex]
⇒ [tex]7x^{6}=2[-21x^{2} +76][/tex]
⇒ [tex]7x^{6}=-42x^{2} +152[/tex]
⇒ [tex]7x^{6}+42x^{2} -152=0[/tex]
Hence we can conclude that the simplified equation is [tex]7x^{6}+42x^{2} -152=0[/tex].

The morning temperature was at 23.5° F. Later that evening the temperature had dropped to 15.6° F. What was the change in temperature?
According to Jake the temperature had a change of -7.9° F.
Is Jake’s answer a true of false statement? Please explain your reasoning for your answer.
Answer:
Jake's answer is true; the change in temperature is -7.9° F.
Step-by-step explanation:
The change in temperature is the final value minus the initial value. Evening minus the morning.
The final value is 15.6° F, the initial value is 23.5° F.
So 15.6 - 23.5 = -7.9
Jake's answer is true.
1. the the sum of three consecutive number is 72. find the number.
Answer:
23,24,25.
Step-by-step explanation:
Consecutive numbers are numbers following in order. I found them unconventionally by first dividing 72 by 3, which is 24. So if there were 3 24s it would make 72. 23+25 is the same sum as 24+24. Then you add in the middle number, 24 and get 72.
Answer:
The answers are 23, 24, and 25
Step-by-step explanation:
Three consecutive numbers means 3 numbers in a row. So just find three numbers that all add up to 72.
23+24+25=72

Answer:
183 divided by 3 = miles per hour
183 / 3 = 61
61 mph
Answer:
61
Step-by-step explanation:
To find unit rate, divide the amount of length to the time. In this instance, 183 miles is the length and 3 hours is the time.
Divide:
183/3 = 61
So, there are 61 miles in 1 hour.

Tara is saving for an overseas trip. Her taxable income is usually about $20000. She estimates that she will need $5000 for the trip, so she is going to do some extra work to raise the money. How much extra will Tara need to earn in order to save the extra $5000 after tax?
An income is taxable is such income falls into a category where a proportion of the income is removed, as tax. To have an extra $5000 after tax, Tara must save $6173.
Given that:
[tex]Earnings = \$20000[/tex] --- normal earnings
[tex]Amount = \$5000[/tex] ---- the amount needed
From the complete question, the tax rate for earnings between $18201 and $37000 is 19%.
Let the additional amount be x.
So, the equation that calculates the amount needed (after tax) is:
[tex]x(1 - 19\%) = 5000[/tex]
Express as decimal
[tex]x(1 - 0.19) = 5000[/tex]
[tex]x(0.81) = 5000[/tex]
Make x the subject
[tex]x = \frac{5000}{0.81}[/tex]
[tex]x = \$6173[/tex]
Hence, she needs to make an extra of $6173 to save $5000

a padock measures 100m x 150m . how many times does jo need to run around it to go 3km?
SIZE
400
UNIT OF MEASURE
meters
BASED ON LANE
1
To begin, you must do Steps 1-3 to enter (or verify) the correct information for the track being used. Frequently-used values have been pre-entered in all three steps. Change them only if required.
Step 1. ENTER THE TRACK SIZE (i.e., the distance covered when completing one lap - normally in Lane 1) and select the unit of measure.
most outdoor tracks are either 400 meters or 440 yards (4 laps to a mile)
most indoor tracks are either 200 meters or 220 yards (8 laps to a mile)
See NOTE 3 for determining track size. Also note that a very small number of tracks use a lane other than Lane 1 to define the track size (see NOTE 4). If the size you entered is not based on Lane 1, select the lane number upon which the size is based.
Step 2. ENTER THE LANE WIDTH of lanes on the track (they should all be the same width). While the best tracks (IAAF, Olympic, etc.) have lanes that are 1.22m to 1.25m wide, most high school and college tracks have lane widths measured in inches (e.g., 42"). See NOTE 5 for information on how to measure lane width. LANE WIDTH
42
Step 3. IS THERE A RAISED CURB on the inside of Lane 1 (normally 2" - 2.5" high)? If there is, select "yes." If the inside edge of Lane 1 is defined only by a painted line, select "no." See NOTE 6 for further information about curbs.
no
Now that you have completed Steps 1 - 3, select a calculation section below, enter the requested parameter(s), and click on the "click here" calculation button for that section. After noting (or printing) the results, enter different parameters for the same calculation or proceed to another calculation section.

What is 15 percent of 1135? Also Explain how you came up with your solution and the actions you took.
Answer:
170.25
Step-by-step explanation:
I made 15% into a decimal. The decimal, being 0.15, was multiplied to 1135 to get the answer 170.25
1135 x 0.15 = 170.25
The value of the percentage is,
→ 15 ÷ 100
→ 0.15
We have to find,
→ 15% of 1135
Let's find the solution,
→ 1135 × 0.15
→ 170.25
Hence, the answer is 170.25.
