Answer:
(x -11) * t + 1067
Step-by-step explanation:
We know that in her tutoring job she earns x amount of money and how waitress earns $ 11 / hour.
They give us the combined number of hours that he works with all the jobs, which is 97, but from here we can say that in the time that he does NOT work as a tutor it is actually 97 - t.
Total earned this month = x * t + 11 * (97 -t)
Total earned this month = x * t + 1067 - 11 * t = (x -11) * t + 1067

1) Marlon had 6 hits in 15 at bats. How does Marlon's
hits to at bats ratio compare to Adrian's?
Answer:
Marlon has a 40% of hits, which means Adrian needs more than 40% to be better.Step-by-step explanation:
We don't have Adrian's batting data, but we can find Marlon's ratio thorugh dividing the hits by the total bats.
[tex]M=\frac{6}{15}=0.4[/tex]
Therefore, Marlon has a 40% of hits, which means Adrian needs more than 40% to be better.

A pillow that usually costs $18 is marked down 25%. Use the table to find the pillow’s new price.
Fill in the missing amounts to solve the problem.
100 percent is an 18 dollar original price, 25 percent markdown is a, and new price is b.
a =
b =
Answer:
In this case we can propose a rule of three:
$ 18 ---------------> 100%
x --------------------> 25%
Where x represents the discount made to the pillow:
So we have the new price (with the discount) is:
In addition, if 25% is discounted we have to, the price of the pillow is 75% of the original price. That is to say:
Step-by-step explanation:
Answer :
a= $4.50
b= $13.50
Step by step explanation: 1- find 25% of 18 which is 4.50. 2- subtract 18-4.50= 13.50
Ann replaces letters in the calculation KAN + GA - ROO with some of the numbers from 1 to 9 and then calculates the result. The same letters are replaced by the same numbers and different letters by different numbers. What is the largest possible result she can get?
Answer:
The largest possible result she can get is 550
Step-by-step explanation:
Here we have that to find the largest possible result, the numbers from which the last number is subtracted from should be the largest possible, hence
Whereby, we had K × A × N + G × A - R × O × O, then;
K ------- 9
A---------8
N---------7
G---------6
A---------8
R---------2
O---------1
O---------1
will give, 504 + 48 - 2 = 550
If however, the A = 7 and N = 8 we have;
504 + 42 - 2 = 544
Hence, the largest possible result she can get = 550.

Answer: 3.4
Step-by-step explanation:
V=4/3•pi•(r)^3
164.636=4/3•pi•(r)^3
164.636/(4/3•pi)= 39.3…
39.3=(r)^3

Hi :) I need help with the question in the screenshot if anybody knows it can you plz help I will give you brainliest, thanks and points!!!!
This question is difficult to give a definite answer to because it's an approximation, but I estimate the solutions to be around x = 2.6 and x = -2.6.
When they ask for solutions of the graphed function they are asking for an approximation of where the graph intercepts the x-axis, and we can see it kind of intercepts in the middle of 2 and 3, except slightly closer to 3, which is why I estimated 2.6.
The graph also appears to be symmetrical, which means the solutions will be the same except one would be negative and one would be positive, which means the second solution would be -2.6.
I hope this helps! Let me know if you have any questions :)

If a cubic polynomial has zeros at x= -4, x=0 and x=7, then
A). The polynomial has no imaginary zeros.
B). The polynomial as a pair of imaginary zeros.
Answer:
A
Step-by-step explanation:
The Fundamental theorem of algebra tells us that a polynomial of degree n has n roots.
Here the polynomial is a cubic, that is of degree 3
Thus it will have 3 roots, real and/ or imaginary.
Since imaginary roots occur in conjugate pairs
Since the polynomial has 3 real roots there are no imaginary roots, thus
A is the required response.

Let's start with one of each choice. That'll be 3 * 4 * 3 * 3 * 10 = 1080 pizzas. As for the second one, this time the toppings won't be 10 it will be 10 * 9 * 8 because we have 10, and then 9, and then 8 topping choices. This gives us 1080 * 9 * 8 = 77,760. Hope this helps!
Answer:
Step-by-step explanation:
Well, we can multiply the choices that they gave us, which is 3 by 4 by 3 by 3 by 10, which will give 1080 for the first part. Now, if you was to do only 3 toppings, it should be 3 by 4 by 3 by 3 by 3, which would give us 324. I don't know if this is right but I think this is the right answer.
The value of Melissa's Jeep is $28,000 and is depreciating at a rate of 14% per year. Use an exponential function to find the value of the Jeep after 6 years. Round to the nearest cent
Help please :/
Answer:
Jeep value after six years is $11,327.9
Step-by-step explanation:
To find the value of depreciation, we use the exponential function below;
V = I(1-r)^t
where V is the future value of the Jeep which we are to calculate
I is the initial value of the jeep which is $28,000
r is the rate of decrease or depreciation which is 14% or simply 14/100 = 0.14
t is time which is 6 years
Plugging these values into the equation, we have;
V = 28,000(1-0.14)^6
V =28,000(0.86)^6
V = 11,327.88
To the nearest cent; V = $11,327.9

The store salsa jars have a height of ten centimeters and a radius of five centimeters. If there is only four centimeters of salsa left in the jar, then determine how much salsa is missing from the jar
Answer:
Step-by-step explanation:
The Salsa jar has a cylindrical shape. We would determine the volume of Salsa that the jar normally contains and the volume left in the jar by applying the formula for determining the volume of a cylinder which is expressed as
Volume = πr²h
Where
r = radius
π = 3.14
For normal volume,
h = 10 cm
r = 5 cm
Volume = π × 5 × 10 = 50π cm³
For volume left,
h = 4cm
Volume = π × 5 × 4 = 20πcm³
Missing volume = 50πcm³ - 20πcm³ = 30π cm³ = 30 × 3.14 = 94.2 cm³

Which fraction is greater than 4/8 a.1/2 b.1/4 c.7/8 d.3/5
Answer:
c and d
Step-by-step explanation:
4/8 = 1/2
a.1/2 =1/2 so it is not greater
b.1/4 < 1/2 = 2/4 so 4/8 is greater
c.7/8 > 4/8 so 7/8 is greater
d.3/5 3/5 = 6/10 1/2 = 5/10
3/5 > 4/8
Answer: 7/8 and 3/5
Step-by-step explanation:
First, let’s look at 4/8 and 1/2. They have different denominations so let’s change them. 2 and 8’s closest multiple that they share is 8. 8/8=1, so we have to multiply the numerator and denominator by 1 which doesn’t change the fraction. 8/2=4, so we have to multiply the numerator and denominator by 4 which makes it: 4/8. 4/8 and 4/8 are the same so they are equal.
Next, let’s look at 4/8 and 1/4. They have different denominations so let’s change them. 4 and 8’s closest multiple that they share is 8. 8/8=1, so we have to multiply the numerator and denominator by 1 which doesn’t change the fraction. 8/4=2, so we have to multiply the numerator and denominator by 2 which makes it: 2/8. 4/8 is greater than 2/8 so this would be a wrong answer.
Then, let’s look at 4/8 and 7/8. They have the same denominations so we don’t have to change them. Let’s look at the numerators though: 4 and 7. 7 is greater than 4 so this answer would be correct.
Finally, let’s look at 4/8 and 3/5. They have different denominations so let’s change them. 5 and 8’s closest multiple that they share is 40. 40/8=5, so we have to multiply the numerator and denominator by 5 which makes it 20/40. 40/5=8, so we have to multiply the numerator and denominator by 8 which makes it: 24/40. 24/40 is greater than 20/40, so this answer is correct.
Hope this helps!
