Which shows two expressions that are equivalent to (Negative 7) (Negative 15) (Negative 5)? (Negative 7) (Negative 75) and (Negative 1) (525) (Negative 1) (525) and (35) (Negative 15) (35) (Negative 15) and (115) (negative 5) (Negative 1) (525) and (115) (negative 5)
Answer: (–1)(525) and (35)(–15) are equivalent to (- 7) (-15) (- 5)
Step-by-step explanation:
Given (- 7) (-15) (- 5)
To Find : Which two expressions that are equivalent (- 7) (-15) (- 5)
(–7)(–75) and (–1)(525)
(–1)(525) and (35)(–15)
(35)(–15) and (115)(–5)
(–1)(525) and (115)(–5)
Solution:
(- 7) (-15) (- 5)
= (105)(-5)
= - 525
(–7)(–75) and (–1)(525)
= 525 & - 525
not Equal

Give two example of point source pollution?-
Give one example of non-point source pollution?-
What are two ways that pollution is still a problem?-
Answer:
look at image your welcome
1. Point-source pollution is easy to identify. As the name suggests, it comes from a single place. it has been defined that point source pollution as any contaminant that enters the environment from an easily identified and confined place. Examples include smokestacks, discharge pipes, and drainage ditches.
2. Nonpoint-source pollution is harder to identify and harder to address. It is pollution that comes from many places, all at once. Nonpoint source pollution can include:
Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas.Oil, grease and toxic chemicals from urban runoff and energy production.
Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks.
3. Pollution is the process of making land, water, air or other parts of the environment dirty and not safe or suitable to use. This can be done through the introduction of a contaminant into a natural environment, but the contaminant doesn't need to be tangible. Things as simple as light, sound and temperature can be considered pollutants when introduced artificially into an environment.Toxic pollution affects more than 200 million people worldwide, according to Pure Earth, a non-profit environmental organization. In some of the world's worst polluted places, babies are born with birth defects, children have lost 30 to 40 IQ points, and life expectancy may be as low as 45 years because of cancers and other diseases. Read on to find out more about specific types of pollution.

Answer:
A is correct
Step-by-step explanation:
Fernando has been saving money to buy an e-book reader. A store has just marked down the price of its readers by 40%. Each reader comes in with a mail-in rebate for $25. The original price of the e-book reader was $150.
How much will Fernando save because of the 40% markdown? Show your work.
Answer:
Fernado saves $90.
Step-by-step explanation:
40% of $150 ( original price ) = $60
$150 - $60 ( original price - discounted price ) = $90 ( savings )
The question asks about the 40% markdown only, so I'd assume you wouldn't reduce it by $25.
But if you did Fernando would save $115 :
40% of $150 ( original price ) = $60
$60 - $25 ( mail-in rebate ) = $35
$150 - $35 ( original price - discounted price ) = $115 ( savings )

Evaluate |-7| + 3|4|
1. 5
2. 0
3. 19
(please provide explanation as to how you got the answer)
Answer:
c. 19
Step-by-step explanation:
The lines surrounding the numbers mean absolute value, which is the distance from zero. Basically what you have to remember is that if it's a positive with this symbol, you keep it the same, if a negative, you change it to positive. In this case, the I-7I would turn into a 7 and then 3*4=12. When you add 12 and 7, it equals 19. Hope this helps! :)

Chance rose his bike for x minutes, and Jaden rode his bike for 3/5 of that.
Part A.
Write and equation, using fractions, that relates the number of minutes chance rode with y, the number of minutes that Jaden rode his bike. 7= __ x
Part B.
Write and equation, using decimals, that relates the number minuts chance rode with y, the number of minutes that Jaden rode his bike. 7= __ x
Answer:
A) 7=4[tex]\frac{1}{5}[/tex]x
B) 7=4.2x
Step-by-step explanation:
A) x÷[tex]\frac{3}{5}[/tex]
7×[tex]\frac{3}{5}[/tex]= 4[tex]\frac{1}{5}[/tex]
B) x÷[tex]\frac{3}{5}[/tex]
[tex]\frac{3}{5}[/tex]=0.6

Jada measured the height of a plant in a science experiment and finds that, to the nearest 1/4 of an inch, it is 4 3/4 inches.
What is the largest the actual height the plant could be?
What is the smallest the actual height the plant could be?
How large could the percent error in Jada’s measurement be?
Answer:
Given that the height(h) of the plant to the nearest 1/4 of an inch is 3/4 inches = 0.75 inches.
it is obvious that the height will lie within the range
2.5/4<h<3.5/4
which corresponds to the range
5/8<h<7/8 OR 0.625<h<0.875
Thus,
a. The largest actual height could be 0.875 inches, while
b. The smallest actual height could be 0.625 inches
c. The percentage error is given by the formula:
[(approx.-exact)/exact]*100%
if we take the lowest value, for instance, as the exact, i.e. 0.625 inches,
then % error = [(0.75-0.625)/0.75]*100% = 16.7%
Obviously, the same value is expected if we take the upper limit of 0.875, i.e. % error = [(0.75-0.875)/0.75]*100% = -16.7%, only that the absolute value will be taken.

What's the banana worth?
Answer:
5!
Step-by-step explanation:
Looking at the first one, you have three watermelons. 36/3 is 12, so one watermelon is worth 12!
With the second one, you subtract 12 from 28 to get 16. Since there are two (peaches?), you divide 16 by two to get the peaches worth, which is 8.
That leaves you with the last one. I used the simple "8 - __ = 3", which got me the answer, 5.
I hope this helped!!

The equations of two functions are y = −25x + 5 and y = −28x + 4. Which function is changing more quickly? Complete the explanation.
The
(select)
function is changing more quickly because the
(select)
of { i have to put a numer}
means that the line has a steeper slope.
Answer:
The y= -28x+4 function is changing more quickly because the -28 of x is the bigger number meaning it is the bigger slope.
Step-by-step explanation:
hopefully that helps, if not let me know of the option you have that I can select from to fully answer the question.
The function changing more quickly is y = - 28x + 4.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The equations of two functions are y = - 25x + 5 and y = - 28x + 4.
We know these equations are in the form of equations of a line in
slope-intercept form.
We know slope defines the rate of change irrespective of the sign.
Therefore, The function which is changing more quickly is y = - 28x + 4,
As |- 28| is more than |-25|.

Mr. Ross is painting a wall that has an area of 142.5 square feet. He uses 3/4 gallon of paint to paint 1/5 of the wall. How many gallons of paint will he need to paint the entire wall?
I don't care what the area of the whole wall is, because we don't need it to solve this problem. It's just there to confuse us.
==> If he used 3/4 of a gallon to paint 1/5 of the wall, then in order to paint the whole wall, he'll have to use 3/4 of a gallon FIVE TIMES.
(5) x (3/4 gallon) = (15/4 gallon) = 3-3/4 gallons
Solving this problem may be painful, but it's not difficult.
