Answer:
$600
Step-by-step explanation:
first, you need to find the unit price which is found by dividing 720 by 6.
so, 720/6 is 120
then, to find the cost of 5 notebooks, you just need to multiply 120 by 5
which would get you 600.
therefore, the total cost of 5 notebooks is $600.
i hope that helps :)
Answer:
600
Divide 720 from 6
= 120
120 x 5 = 600

3. Solve the equation for x: 3x - 4 = 7x + 8
Answer:
=−3
Step-by-step explanation:
Answer:
B) x = -3
Step-by-step explanation:
3x - 4 = 7x + 8.
Subtract 7 from 3
3 - 7 = -4
-4x - 4 = 8
use additive inverses.
-4x - 4 + 4 = 8 + 4
8 + 4 = 12.
-4x ÷ -4 = 12 ÷ -4
x = -3.
Hope this helped.
A quantity with an initial value of 920 decays exponentially at a rate of 85% every week. What is the value of the quantity after 21 days, to the nearest hundredth?
Answer:
≈3.11
Step-by-step explanation:
The value of the quantity after 21 days, to the nearest hundredth, given the expoenential decay is 3.11.
What is the value of the quantity after 21 days?When a quantity decays , it means that the value of the quantity declines with the passage of time.
The formula that can be used to determine the value of the quantity after a number of weeks is :
FV = P (1 - r)^n
Where:
FV = Future valueP =initial valueR =rate of decayN = number of weeks = 21/7 = 3 weeks920 x (1 - 0.85)^3
920 x 0.15^3 = 3.11

The area of a rectangle is 32 square inches. The length is 4 inches more than its width. Write and solve an equation to find the length and width of the rectangle. Show your work.
Answer:
Width = 4 in
Length = 8 in
Step-by-step explanation:
Given:
Area of a rectangle = 32 in²
Find:
Length and width
Computation:
Assume;
Width = x
Length = x + 4
Area of a rectangle = lb
32 = (x+4)(x)
x² + 4x = 32
x² + 4x - 32 = 0
x² + 8x - 4x - 32 = 0
x(x+8) - 4(x+8) = 0
(x-4)(x+8)
x = 4 , x = -8
So,
Width = x = 4 in
Length = x + 4 = 4 + 4 = 8 in

A group of friends went to lunch. Click on all the correct answers below according to the Letters A, B, and C.
A Their original bill cost $50.00, but they had a coupon for 20% off their meal. Find the discounted price (before tax and tip).
B A sales tax of 7% was added. What was the total amount including sales tax?
C The group chose to tip 20%. What is the total amount that their bill cost including tax and tip?
Answer:
A. 10.00, so total price is currently 40.00
B. 42.8
C. Total amount is 51.36
Step-by-step explanation:
20% of 50 is 10. Taking off 10% (your discount) would make it 40.
7% of 40 is 2.8. The total amount is now 42.8
20% (your tip) of 42.8 = 8.56.
42.8 + 8.56 = 51.36.
51.36 is your final cost.

A door delivery florist wishes to estimate the proportion of people in his city that will purchase his flowers. Suppose the true proportion is 0.05. If 408 are sampled, what is the probability that the sample proportion will differ from the population proportion by greater than 0.03?
Answer:
The probability is [tex]P( | \^ p - p| > 0.03) =0.9945[/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is [tex]p = 0.05[/tex]
The sample size is n = 408
Generally the standard deviation of the sampling distribution is mathematically represented as
[tex]\sigma = \sqrt{\frac{p (1- p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{ 0.05 (1- 0.05)}{408} }[/tex]
=> [tex]\sigma = 0.0108[/tex]
Generally the probability that the sample proportion will differ from the population proportion by greater than 0.03 is mathematically represented as
[tex]P( | \^ p - p| > 0.03) = P( \frac{|\^ p - p | }{\sigma } > \frac{0.03}{0.0108} )[/tex]
[tex]\frac{|\^ p -p |}{\sigma } = |Z| (The \ standardized \ value\ of \ |\^ p -p | )[/tex]
So
[tex]P( | \^ p - p| > 0.03) = P( |Z|> 2.778 )[/tex]
=> [tex]P( | \^ p - p| > 0.03) = P( Z < 2.778) - P(Z < -2.777)[/tex]
From the z table the area under the normal curve to the left corresponding to 2.778 and -2.778 is
[tex]P( Z < 2.778) = 0.99727[/tex]
and
[tex]P( Z < -2.778) = 0.0027347[/tex]
So
[tex]P( | \^ p - p| > 0.03) = 0.99727 - 0.0027347[/tex]
=> [tex]P( | \^ p - p| > 0.03) =0.9945[/tex]
Why is y=-12.5x have a proportional relationship
Answer:
A proportional relationship is any relationship that stays constant. since both sides of the equation do not change, this is a proportional relationship
Find three consecutive positive integers such that the product of the first
two is 22 less than 11 times the third. (Type the answers in order - from
lowest to highest) *
Answer: 10,11,12
Step-by-step explanation:
1st integer= x-1
2nd integer= x
3rd integer= x+1
(x-1)(x) = 11(x+1)-22
x^2-x = 11x+11-22
simplify to: x^2-12x+11=0
factor to: (x-11)(x-1)
x=11, 1
1 doesn’t work because that would make the 1st integer equal to 0, and 0 isn’t a positive integer. So the three integers are 10, 11, and 12.

What is the question ??
How do I solve the problem ??
Answer:
[tex]-x-3[/tex]
Step-by-step explanation:
They want you to simplify the expression.
Step 1: Apply the distributive property.
[tex]\frac{1}{5} (5x)+\frac{1}{5} (-15-2x)[/tex]
Step 2: Cancel the common factor of 5.
[tex]x+\frac{1}{5} (-15-2x)[/tex]
Step 3: Cancel the common factor of 5.
[tex]x-3-2x[/tex]
Step 4: Subtract 2x from x.
[tex]-x-3[/tex]
