Answer:
f(- 3) = 40
Step-by-step explanation:
To evaluate f(- 3), substitute x = - 3 into f(x), that is
f(- 3) = - 2(- 3) - 9(- 3) + 7 = 6 + 27 + 7 = 40

I see a fraction. Don't you. Here it is 17/20. Now, let's divide 17 by 20 to get a decimal number, which is 0.85. Next, we multiply 0.85 by 100 to get the percent because that is what the question desires for us to express our answer. As a result, we get 85%, and Antonio made 85% of his free throws. By the way, I hope my response helps you.
Step-by-step explanation:
1 way is to do 17/ 20 using long division...
0. 85
20⟌1700 ( I tried my best)
- 160
100
So the answer would be 85%
Another way to do it is by bringing the denominator to 100
Since 20 is 1/5 of 100, you would have to multiply the numerator and denominator by 5
17/ 20 = 17*5/ 20*5 = 85/ 100
And you get 85%

Can someone help me with this please
Answer:
y=75
Step-by-step explanation:
Alright first off you want to be able to find the ratio to this to be able to find that Y you are looking for.
If you simplify y=45 and x=3 both by 3 you will get:
y=15 and x=1
now, lets turn that X to a 5 just like the other x which equals 5 as well...
but here's the catch when you times our X by 5 to equal 5 we are also going to times our Y by 5 to and do you know what 15 times 5 is it's 75.
now that we know that let's type that out to make it clear:
x=5 and y=75
you see the pattern now ;)

Which shows how the distributive property can be used to evaluate 7 times 8 and four-fifths?
56 + StartFraction 28 over 5 EndFraction = 56 + 5 and three-fifths = 61 and three-fifths
56 times StartFraction 28 over 5 EndFraction = StartFraction 1568 over 5 EndFraction = 313 and three-fifths
15 + (StartFraction 35 over 5 EndFraction + four-fifths) = 15 + StartFraction 39 over 5 EndFraction = StartFraction 75 over 5 EndFraction + StartFraction 39 over 5 EndFraction = StartFraction 114 over 5 EndFraction = 22 and four-fifths
15 times (StartFraction 35 over 5 EndFraction + four-fifths) = 15 times StartFraction 39 over 5 EndFraction = StartFraction 15 over 1 EndFraction times StartFraction 39 over 5 EndFraction = StartFraction 585 over 5 EndFraction = 117
Answer:
I have no clue as to what the options were, but the answer is 61 and three-fifths.
Step-by-step explanation:
Well, the fraction options were a little distorted, so I'll work it out anyway.
7 • 8 4/5
7(8 + 4/5)
7 • 8 is 56, and 7 • 4/5 is 28/5.
56 + 28/5
28/5 as a mixed-number fraction (I think that's what it's called) is 5 3/5.
56 + 5 + 3/5
61 + 3/5
61 3/5 (61 and three-fifths)
There!
(Sorry about not getting the options...)

Answer:
120°
Step-by-step explanation:
From the above question, the polygon is and hexagon, this means it has 6 sides.
Hence: Sums of the interior angles of a polygon = Sum = (n-2) × 180°
n = 6
Hence,
Sum of the interior angles = (6 - 2) × 180°
= 4 × 180°
= 720°
Hence:
The measure of an interior angle of a hexagon =

Nicholas wants to buy a new computer that is on sale for $899. His parents will loan him the money if he repays them. He has $225 in his savings account and plans to work as a camp counselor to earn money during the summer. If he earns $35 per day, how many days will Nicholas have to work in order to fully repay his parents?
Answer:
20 days
Step-by-step explanation:
899- 225= 674
674÷ 35= 19.257....
which you would round it up to 20 because he would have to work the extra day because you need more than less.

What is the probability that a point chosen at random on the grid will lie in the shaded region?
36%
40%
64%
60%
Given:
A grid with a shaded region.
To find:
The probability that a point chosen at random on the grid will lie in the shaded region.
Solution:
We have,
Total number of small boxes = 100
Number of blue boxes (shaded region) = 36
Now,
probability that a point chosen at random on the grid will lie in the shaded region is
[tex]\text{Probability}=\dfrac{\text{Number of blue boxes (shaded region)}}{\text{Total number of small boxes}}[/tex]
[tex]\text{Probability}=\dfrac{36}{100}[/tex]
To find the probability in percent, multiply it by 100.
[tex]\text{Probability}\%=\dfrac{36}{100}\times 100[/tex]
[tex]\text{Probability}\%=36\%[/tex]

Two savings accounts earn simple interest. Account A has a beginning balance of $500 and grows by $25 per year. Account B has a beginning balance of $750 and grows by $15 per year.
Answer:
After 25 years both the accounts will have the same balance.
Step-by-step explanation:
Let t years, both the account will have the same balance.
As account A has a beginning balance of $500 and grows by $25 per year.
So, the total balance of account A after t years = 500+25t
Similarly, account B has a beginning balance of $750 and grows by $15 per year.
So, the total balance of account A after t years = 750+15t
As both the accounts has the same balance, so
500+25t= 750+15t
25t-15t=750-500
10t=250
t=250/10
t=25 years
Hence, after 25 years both the accounts will have the same balance.
Substitution algebra
Please answer fast :) Don't answer this with troll stuff plz, I don't have much points
We will use substitution to solve the system. Step 1 is partially complete.
[tex]y = -2x - 9\\6x - 5y = -19\\\\6x - 5(-2x - 9) = -19\\\\6x + 10x + 45 = -19\\\\16x + 45 = -19\\\\16x = -64\\\\x = -4[/tex]
We will now use what we got for x to solve for y in one of the original equations.
[tex]6(-4) - 5y = -19\\\\-24 - 5y = -19\\\\-5y = 5\\\\y = -1[/tex]
The solution is (-4, -1).

Jen and Eric cleaned the kitchen floor together. Jen cleaned 2/7 pf the floor, and Eric cleaned 3/7 of the floor. How much of the floor did they clean in all?
Answer:
5/7
Step-by-step explanation:
You are adding both fractions together to determine the total of the floor they both cleaned in all.
so 2/7 + 3/7 =
To add fractions, you need both denominators to be the same. In this case, they are already the same so you don't need to adjust the fraction before adding them.
Now all you need to do is to add the numerators together so
2 + 3 = 5
So you put the numerator total over the common denominator.
* You do not add the denominators, only the numerators.

Alice,belle and Chloe each played a game. Alice score was five times belles score. Chloes score was two times Alice’s score. Wrote down the ratio of Alice’s score to belles score to chloes score
Answer:
Alice : Belles : Chloe
5 : 1 : 10
Step-by-step explanation:
If we represent Belles score as x, we can tell the following.
Alice's score will be 5x since her score is 5 times Belles score (5)(x)
Chloe's score is 10x since her score is 2 times Alice's score (2)(5x)
Now we can see the following ratio.....
Alice : Belles : Chloe
5x : x : 10x
(get rid of the x and the get)
Alice : Belles : Chloe
5 : 1 : 10
The ratio of Alice's score to Belle's score to Chole's score is 1 : 5 : 10.
What is ratio?The relationship between two numbers which shows how much bigger one quantity is than another.
According to the given question
Alice's score was five times Belle's score.
Chloe's score was two times Alice's score.
Let Belle's score be x.
Therefore,
Alice's score = 5x
Chloe's score = 2×5x = 10x
So,
ratio of Alice's score to Belle's score to Chole's score = x : 5x : 10x
⇒Alice's score: Belles's Score: Chole's score = 1 : 5 : 10

You deposit $400 in an account. The account earns $18 simple interest in 9 months. What is the annual interest rate
Use the formula,
I = Prt
P = Principal amount = 400
I = interest = 18
r = annual rate
t = time in years = 9/12 = 3/4
so,
18 = 400*r*3/4
r = 0.06
so the annual interest rate is 0.06 or 6%.
