What is the unit rate for 3.5 GB for $10.00
PLEASE ANSWER CORRECTLY
Answer:
$76.32
Step-by-step explanation:
First, add up all the costs for everything:
17 + 30 + 25 = 72
Now, we need to add the sales tax. To do this we multiply 72 by 1.06. This is because the sales tax is 6% (the decimal form of 6% is 0.06), and we add it on to the 100% cost (which is 1 in decimal form).
(72)(1.06) = 76.32
Therefore the total cost of everything Walter bought plus the tax rate is $76.32.
I hope this helps!!

Dan invests £18790 into his bank account. He receives 5,3% per year simple
interest. How much will Dan have after 7 years? Give your answer to the nearest
penny where appropriate,
Answer:
697109 pennies
Step-by-step explanation:
First, you use the formula A = P (1 + rt).
R= rate which is 5.3%
T= time which is 7 years.
P is the principle which is 18790
A= is the answer
so first you multiply 7*5.3% which you get 0.371
then you multiply that with 18790 which then you get 6971.09
if you want pennies you multiply it with 100 to get 697109
A gas station sells 1600 gallons of gasoline per hour if it charges $ 2.70 per gallon but only 900 gallons per hour if it charges $ 2.95
per gallon. Assuming a linear model
(a) How many gallons would be sold per hour of the price is $ 2.90 per gallon?
Answer:
(b) What must the gasoline price be in order to sell 1300 gallons per hour?
Answer:
Answer:
Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).
Slope m=%281600-800%29%2F%280.15-0.55%29
m=800%2F0.40
m=2000
Using point-slope form for a line, and the lower-y point,
y-800=2000%28x-2.55%29
highlight%28y=2000%28x-2.55%29%2B800%29

Answer:
adjust city gallons to 3 gallons and freeway to 7 gallons
make your line in the chart:
3 | 10-3 = 7 | 3(25) = 75 | 7(40) = 280 | 75 =280 =355 | 355 | yes
Step-by-step explanation:
x = city gallons
y = freeway gallons
x+y = 10 then y = 10-x
25x+40y = 355
substitute for y
25x+40(10-x) = 355
25x+400-40x = 355
-15x+400 = 355
subtract 400 from each side
-15x = -45
divide both sides by -15
-15x/-15 = -45/-15
x = 3 gallons
y = 7 gallons

X^3+9X^2–25X–33=0
Find The root of X??
Answer:
x=-11, -1, and 3
Step-by-step explanation:
x^3+9x^2-25x-33=0
There are formulas to solve cubics, but that probably is not the way you are expected to go. Here is a trial and error approach that works in this case.
Assume that the cubic can be factored and that the roots are r1, r2, and r3. Then the factored form is
(x-r1)(x-r2)(x-r3)=0
This shows that the constant must equal the product of the roots.
(r1)(r2)(r3)=-33
One possibility is that the roots are integers. In this case, a factor of 33 might work. Prime factorization of 33 gives 3 and 11. Try 3. Then (x-3) is a factor.
Divide the cubic by (x-3). It works. the result is
x^2+12x+11
This has factors of (x+11) and (x+1). Therefore, the roots are 3, -1, and -11

Answer and Step-by-step explanation:
Let's solve your equation step-by-step.
−2(x+5)=4
Step 1: Simplify both sides of the equation.
−2(x+5)=4
(−2)(x)+(−2)(5)=4(Distribute)
−2x+−10=4
−2x−10=4
Step 2: Add 10 to both sides.
−2x−10+10=4+10
−2x=14
Step 3: Divide both sides by -2.
-2x/2 = 14/-2

answer and show work and ill give brainliest, Steven has one bag that contains three table-tennis balls numbered 1, 2, and 3. He also has a second bag that contains four table-tennis balls lettered A, B, C, and D.
Answer:
B
Step-by-step explanation:
Assuming Part A is the situation where the bags aren't merged, the probability of drawing a "1" followed by a "B" is (1/3)(1/4) or 1/12. This is because you have a 1/3 chance of getting a "1" and a 1/4 chance of getting a "B".
Now if we merge the bags, we have a 1/7 chance of getting a "1". We then have a 1/6 chance of getting a "B". This is because after we complete the first draw, the bag only has 6 remaining not 7. This gives us a probability of (1/7)(1/6) or 1/42.
So we know the probability will change so C is wrong. In both scenarios, we draw two balls anyways so A is wrong.
This leaves B, which is supported by the reasoning presented above.
can someone help me with this?

Finding Anglessss
Answer:
I got 104
Step-by-step explanation:
From our given information, since Angle DGF from a 90 degree angle, Due to our linear pair rule EGF is also a perpendicular angle. EGF and DGC are vertical angles so Angle DGC is 90 degrees.
Triangle DGC have two interior angles 90 and 37 so using the triangle interior theorem we can find the 3r
d side
[tex]90 + 37 + x = 180[/tex]
[tex]127 + x = 180[/tex]
[tex]x = 53[/tex]
Know that angle is 53 we can add 53 and 51 together to find Angle D full degree measure is 104.
Adjacent angles in parallelogram are supplementary so angle d plus angle c equals 180.
Angle C measure has to add up to 76 then so
[tex]37 + x = 76[/tex]
[tex]x = 39[/tex]
So the missing angle is 39 and angle c full side measure is 76.
Angle B and Angle C
are also adjacent angles so
[tex]76 + x = 180[/tex]
x=104
B=104
Write an expression to show k less than 10
Step-by-step explanation:
"Write an expression to show k less than 10"
"less than" means that the number is being subtracted from a different number.
This means that "10" is being subtracted from "k"
Thus,
k - 10 is the appropriate expression for the statement, "k less than 10"
ANSWER: k - 10
pls make sure ur answer is correct

In 1985, there were 20 students
In 2005, there were 45 students
This is a change of 45-20 = 25 students.
This amount of change is divided by the original amount 20 to get 25/20 = 1.25 and converts to 125% when you move the decimal point 2 spots to the right.
-------------
If you want, you can use the formula below
x = old value = 20
y = new value = 45
z = percent change
z = [ (y-x)/x ] * 100%
z = [ (45-20)/20 ] * 100%
z = (25/20) * 100%
z = 1.25*100%
z = 125%
The z value being positive means we have a percent increase.
It's possible to have over 100% increase since 100% of 20 is 20. Having a 100% increase means we increased by 20. Since we increased by more than 20, this means the increase must be over 100%.
