Answer:
A.
Step-by-step explanation:
Graph B must be incorrect as this is a directly proportional relationship. Likewise, graph C shows an inversely proportional relationship.
Between graph A and D, only graph A passes through the origin, which is true because if length is zero, perimeter is zero.
Hence the answer is Graph A.

What is 7.5 × 10^18 and 7 × 10^27 plz help ty
7.5 x 10^18: Since the exponent of the scientific notation is positive, move the decimal point 18 places to the right.
AN: 7500000000000000000
7 x 10^27: Since the exponent of the scientific notation is positive, move the decimal point 27 places to the right.
AN: 7000000000000000000000000000
Answer:
7,500,000,000,000,000,000 and 7,000,000,000,000,000,000,000,000,000
Step-by-step explanation:
I would assume that's in scientific notation, so to solve you need to get it out of scientific notation.
Since the exponent is positive, move it that many places to the right.
For the first one, it would be 7,500,000,000,000,000,000.
For the second one, it would be 7,000,000,000,000,000,000,000,000,000.
If the exponent was negative, you would've moved the decimal to the left instead.
Hope this helped. It's the only way I could think of to solve it.
.How much force is needed to accelerate a truck with a mass of 2,000 kg, at a rate of 3 m/s²?
The force needed to accelerate a truck with a mass of 2,000 kg, at a rate of 3 m/s² is 6000 Newtons.
What is force?Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces. For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.
Given:
The mass of the truck = 2000 kg,
The acceleration of the truck = 3 m/s²,
Calculate the force as shown below,
Force needed for truck = Acceleration of truck × mass of the truck,
Force = 2000 × 3
Force = 6000 N

Answer:
b
Step-by-step explanation:
Please help. Need help
Answer:
C
Step-by-step explanation:
To do this, let's let the decimal equal n. Thus:
[tex]2.\bar1=n[/tex]
There is only one digit repeating, so let's multiply both sides of the equation by 10:
[tex]21.\bar1=10n[/tex]
Now, subtract n from both sides:
[tex]21.\bar1-n=10n-n[/tex]
On the right, it becomes 9n. However, the left, however, expand, the decimal. In other words:
[tex]21.1111...-2.1111...=9n[/tex]
All of the repeating 1s will cancel out. Thus:
[tex]21-2=9n[/tex]
Subtract:
[tex]19=9n[/tex]
Divide both sides by 9:
[tex]n=\frac{19}{9}[/tex]
And since we set the decimal equal to n originally...
[tex]2.\bar1=\frac{19}{9}[/tex]
And we're done!
Notes:
This is the algebraic way to write a repeating decimal into a fraction. You can, of course, always just use a calculator and guess and check.
It's A. 21/10
What I did to get this. Is i wrote down 2.1 as a fraction: 2.1/1 then multiplied 10 to both the numerator and the denominator. (2.1 x 10)/(1 x 10)=21/10.

Answer:
1 square for every 4 circles
1:4
1/4
Step-by-step explanation:
To get it to the simplest ratio all you have to do is put the given numbers (8,2) into fraction form based on the order given in the question. The order given was "squares to circles". This makes squares the numerator and circles the denominator. After you set it into a fraction just reduce the fraction to its simplest form.

Determine the whole if the part is 126 and the percent is 90%
Answer:
Hey there!
We can arrange this to say, "90% of the whole is 126."
Thus, we can write an equation, where w is used as a variable to represent the whole.
0.90w=126
Divide by 0.90
w=140
The whole is 140.

At the beginning of the season, Jamie pays full price for a ticket to see Panters, her favorite baseball team. The Panthers currently have 33 wins and 31 losses. A. Represent the total change in the cost of a ticket given in their losses. B. What is the cost of a ticket for the next game they play?
Answer:
The answer is B i think
Step-by-step explanation:
Answer:
a) The cost of the ticket decreases by $0.41 for every game loss, therefore after 31 losses, the change in cost of ticket is given as:
Change in cost = -$0.41 × number of losses = -$0.41 × 31 = -$12.71
b) The cost of a ticket for the next game given they have 31 losses is:
Cost of ticket = Initial cost of ticket + change in cost = $49.64 - $12.71 = $36.93
