Darias bought 5 school binders that cost $8.00 per
binder. If a back-to-school discount of 40% was
applied to his purchase, and then a 6% sales tax was
added, what was the total cost of the binders?
Answers
Answer:
$25.44
Step-by-step explanation:
First, find the original cost of the binders:
5(8)
= $40
Find the cost with the 40% discount:
40(0.6)
= $24
Find the cost with the 6% sales tax:
24(1.06)
= $25.44
So, the total cost of the binders was $25.44

SUBMI
Answers
Answer:
Both ends go down
Step-by-step explanation:
The end behavior of the function are Both ends go down. Therefore, Option C is true.
Given that,
The function is,
[tex]f (x) = - 2 (x - 17)^4[/tex]
Now the given function is defined at x → ∞,
f (x) = - 2 × ∞
f (x) → - ∞
As x goes to -∞
f(-∞) = -2(-∞)⁴
= -2 (∞)
= -∞
So, Both ends go to -∞, or go down
Hence, The end behavior of the function are Both ends go down.
Therefore, Option C is true.

Find the equation of the linear function represented by the table below in slope-intercept form.
Answers
Answer:
y = 3x+1
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= (13-4)/(4-1)
= 9/3
= 3
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 3x+b
Using a point from the table
10 = 3(3)+b
10 =9+b
10-9 =b

The altitude (i.e., height) of a triangle is increasing at a rate of 2 cm/minute while the area of the triangle is increasing at a rate of 1.5 square cm/minute. At what rate is the base of the triangle changing when the altitude is 12 centimeters and the area is 99 square centimeters
Answers
Answer:
A = 1/2 B H area = 1/2 base X height
B = 2 A / H = 2 * 99 / 12 = 16.5 cm
dA / d t = 1/2 * (B dH / dt + H dB / dt)
dB / dt = (2 dA / dt - B dH / dt) / H
dB / dt = (2 * 1.5 cm^2 / min - 16.5 cm * 2 cm / min) / 12 cm
dB / dt = (3 - 33) / 12 cm/min = -2.5 cm/min
Easton is going to invest $340 and leave it in an account for 8 years. Assuming the interest is compounded quarterly, what interest rate, to the nearest tenth of a percent, would be required in order for Easton to end up with $420?
Answers
Answer:
100.7%
Step-by-step explanation:
Since the interest is compounded quarterly, and there are 4 quarters per year, that would leave us with 32 quarters total where interest is acquired. Now, we need to find the interest rate, that would be required in order to end up with 420 dollars after 32 quarters.
We can setup a formula using our period of time and the money he invested into the bank:
[tex]340(x)^{32}=420[/tex]
We can divide 340 from both sides, and simplify the right side to 21 divided by 17:
[tex]x^{32}=\frac{21}{17}[/tex]
Taking the 32th root of 21/17 is equal to 1.00662, which is equal to 100.0662%. To the nearest tenth of a percent, this is equal to 100.7%.

Answers
Answer:
19982Step-by-step explanation:
As we know all primes but 2 are odd numbers.
It means sum of any 3 primes not including 2 is odd.
Since we have sum of 202, one of our primes is 2.
Sum of the other two primes is 200.
In order to have maximum value of p*(200 - p) these two numbers must be closer to each other. So we are looking for two primes around 100.
We can test all primes less than 200:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, and 199The 3 primes with max product are:

Find the area of the small square
A = lw
= (2)(2)
= 4 cm^2
Find the area of the large square
A = lw

Step-by-step explanation:
2(2×6+2×2+2×6) + 2(4×5+4×10+10×5) - 2(2×2)
= 56+220-8
= 268 cm²
Answer:
272cm
Step-by-step explanation:
So the green block has 6 sides
the height of the prism is 4cm
the length is 10cm
and the width is 5cm
to find the top and bottom sides we must find the width and length
5x10=50cm so The bottom and top are double that so 100cm is covered so far
to find the longer sides, we times 4 by 10 = 40x2 = 80cm which covers 2 sides
and the last 2 sides of the green block are the smaller ones so 4x5 = 20 but that covers one side so we times by 2 andd that gives us both sides so 40cm
all 6 sides are covered so we can add up the numbers
top and bottom = 100cm
front back = 80cm
left and right = 40
add them all up and we get 220
now we see the purple block, this is the Same process as before
top = 2x2 = 4
bottom = 2x2 = 4
front = 6x2 = 12
back = 6x2 = 12
left = 6x2 = 12
right = 6x2 = 12
add them together and we get 56cm
the surface area of both of them Is 220+56 = 276cm
however the bottom of the purple prism is on top of the top of the green prism. Because we know the surface area of the bottom of the purple (4) and the top Surface of the green (50).
this allows us to subtract the prism above because of the bottom shapes surface so the actual answer is 272cm hope this helped
The average of four different positive integers is 9. What is the greatest value for one of the integers?
Answers
From the given information; Let the unknown different positive integers be (a, b, c and d).
An integer is a set of element that are infinite and numeric in nature, these numbers do not contain fractions.
Suppose we make an assumption that (a) should be the greatest value of this integer.
Then, the other three positive integers (b, c and d) can be 1, 2 and 3 respectively in order to make (a) the greatest value of the integer.
Therefore, the average of this integers = 9
Mathematically;
[tex]\mathbf{\dfrac{(a+b+c+d)}{4} =9}[/tex]
[tex]\mathbf{\dfrac{(a+1+2+3)}{4} =9}[/tex]
[tex]\mathbf{\dfrac{(6+a)}{4} =9}[/tex]
By cross multiplying;
6+a = 9 × 4
6+a = 36
a = 36 - 6
a = 30
Therefore, we can conclude that from the average of four positive integers which is equal to 9, the greatest value for one of the selected integers is equal to 30.

9. Write an equation in slope intercept form that
passes through (6,2) and (-3.0)
Answers
Answer:
y = -2/9x+2/3
Step-by-step explanation:
First find the slope
m= (y2-y1)/(x2-x1)
= (0-2)/(-3-6)
= -2 /-9
2/9
The slope intercept form is
y= mx+b where m is the slope and b is the y intercept
y = 2/9x+b
Using the point -3,0
0 = 2/9(-3) +b
0 = -2/3+b
b = 2/3
y = -2/9x+2/3
