determine the final price of an item that costs $75 and is 10% off show working
Answers
Answer:
67.5$
Step-by-step explanation:
75$ x .10 = 7.5$
75$ - 7.5$ = 67.5$
Answer:
$67.50
Step-by-step explanation:
First, find the discount.
Multiply the discount rate by the cost.
discount rate * cost
The discount rate is 10% and the cost is $75.
$75 * 10%
Convert 10% to a decimal. Divide 10 by 100 or move the decimal place two spots to the left.
10/100 = 0.10 or 10.0 --> 1.0 --> 0.10
$75 * 0.10
$7.5
Now, find the final price.
Since it is a 10% discount, we must subtract the discount amount from the cost.
cost - discount
The cost is $75 and the discount is $7.5
$75 - $7.5
$67.50
The final price of a item that costs $75 with a 10% discount is $67.50
Si el divisor de una división es 67, el cociente es 495 y el residuo es 31, ¿cuál es el valor del dividendo? A. 33.196 B. 33.264 C. 34.412 D. 34.528
Answers
Answer:
Divisor = 67, Cociente = 495
Resto = 31
Dividendo = Cociente × Divisor + Resto
Dividendo = 495 × 67+ 31
= 33165 +31
= 33,196

Solve the equation t - 8 = -3.
Answers
Answer: [tex]t=5[/tex]
Add 8 to both sides
[tex]t-8+8=-3+8\\t=5[/tex]
Answer:
The correct answer is t = 5.
Step-by-step explanation:
To solve this question, we must first recognize that our goal is to get the variable t by itself. To do this, we should add 8 to both sides of the equation to get rid of the -8 on the left side of the equation. This is modeled below:
t - 8 = - 3
t - 8 + 8 = -3 + 8
t = 5
Therefore, the correct answer is t = 5.
If we want to check our answer, we can plug in 5 for t in the original equation. If we do this, we get: 5 - 8 = -3, which is a true statement, so we know that we did the problem correctly.

In the Mississippi River Delta, fresh water (0% salinity) mixes with salt water from the Gulf of Mexico (3 1 2% salinity). If 1,000 gallons of river water mixes with 3,000 gallons from the Gulf, how many gallons result, and what is its percent salinity? (Estimate a reasonable percent range for your answer before you solve.)
Answers
Answer:
The total resulting gallons of water is 4,000 gallons
The concentration of the resulting solution is 2.625% salinity
Step-by-step explanation:
The salinity of the fresh water from the Mississippi River Delta = 0%
The salinity of the water from the Gulf of Mexico = 3 1/2%
Therefore, if 1,000 gallons of river water mixes with 3,000 gallons from the Gulf, we have;
The total resulting gallons of water = 1,000 + 3,000 = 4,000 gallons
The total resulting gallons of water = 4,000 gallons
The concentration of the resulting solution is found as follows;
The concentration of the resulting solution = (3 × 3 1/2)/400 × 100 = 2.625%
The concentration of the resulting solution = 2.625% salinity.

The discount at WalMart is 20%. The bill for
If the TV was originally $800 how before tax
much did I actually pay?
9.5% wha
Answers
Answer:
$700.8
Step-by-step explanation:
discount = 0.20
You actually pay full price (100% or 1) - discount (20% or 0.20), so 1 - 0.20 = 0.80
If the TV was originally $800, then you pay 0.80 (80%) of it, or
(800)(0.80) = $640.00 dollars.
Tax, 9.5% or 0.095, of $640 is added to the $640, so
Tax = 0.095 + 640 = $60.8
$60.8 + $640 = $700.8

Explanation:
Notice how the point to the very far right is an outlier. See the diagram below. The line of best fit in red goes through (or close to) the cluster of points to the left of this outlier location. It's not the best fit ever, but it's close enough. The drawing I did is my best guess. Without knowing the actual numbers, it's impossible to get the actual regression line.
The location of this outlier is (x,y) = (7,4). This means x = 7 and y = 4 pair up together. Since x is the width and x = 7, this means a width of 7 is an outlier.
A graduated cylinder is filled to an initial volume of 20ml. A ball is dropped into the graduated cylinder. The final volume of the graduated cylinder is 29 ml. If the has a mass of 27 g. What is the density of the ball?
Answers
Hey there! I'm happy to help!
A graduated cylinder is basically a cylinder with little measurements on it.
If we drop the ball into the cylinder and the final volume in 29 instead of 20, this means that the ball has a volume of 9 mL as it took up 9mL of the water, pushing it up 9 mL.
Density is mass divided by volume. The ball has a mass of 27 g and a volume of 9mL. So, the density is 3 g/mL.

A circular region has population of about 15,500 people and a population density of about 775 people per square kilometer find the radius of the region
Answers
Answer:
Radius of the region = 2.5 km (Approx)
Step-by-step explanation:
Given:
Total population = 15,500
Density = 775 people per square kilo meter
Find:
Radius of the region
Computation:
Total ares = 15,500 / 775
Total ares = 20 km
Total ares = πr²
20 = (22/7)r²
r² = 6.363636
r = 2.52
Radius of the region = 2.5 km (Approx)
Bill and gwyll are going on holiday to the USA. Bill changes £450 into $729 Gwyll changes £500 into $780 What exchange rate did bill get? What exchange rate did Gwyll get?
Answers
Answer:
Bill's exchange rate was $1 to £1.62
Gwyll's exchange rate was $1 to £1.56
Step-by-step explanation:
Given
Bill changed £450 into $729
Gwyll changes £500 into $780
Required
Determine their exchange rates
Exchange rate is calculated by dividing the currencies against one another.
Given that they both changed from pound to dollar, the exchange rate is calculated as thus;
[tex]Rate = \frac{Amount\ in\ pound}{Amount\ in\ dollar}[/tex]
Calculating Bill's Exchange Rate
[tex]Rate = \frac{\£729}{\$450}[/tex]
[tex]Rate = \frac{\£1.62}{\$1}[/tex]
Represent as a ratio
[tex]Rate = \£1.62:\$1[/tex]
Hence, Bill's exchange rate was $1 to £1.62
Calculating Gwyll's Exchange Rate, using the same formula and steps
[tex]Rate = \frac{\£780}{\$500}[/tex]
[tex]Rate = \frac{\£1.56}{\$1}[/tex]
Represent as a ratio
[tex]Rate = \£1.56:\$1[/tex]
Hence, Gwyll's exchange rate was $1 to £1.56
Write and solve an equation to determine how many degrees the temperature T fell. The temperature at 5 P.M. Is 20∘F. The temperature at 10 P.M. Is −5∘F.
Answers
Temperature fell 25° [tex]\\[/tex]
5 PM => 20
10 PM => -5
Find the difference between both temperatures at 5 PM and 10 PM
T = 20 - ( -5) = 20 + 5 = 25
The reason we subtracted 10 PM from 5 PM (20 - ( -5)) and not the other way around is because 5 PM obviously comes before 10 PM.
3(c-1)+2(3c+1)=-(3c+1)
Answers
Answer:
c=0
Step-by-step explanation:
3(c-1)+2(3c+1)=-(3c+1)
Distribute
3c -3 +6c +2 = -3c -1
Combine like terms
9c -1 = -3c -1
Add 1 to each side
9c = -3c
Add 3c to each side
12c = 0
Divide by 12
c = 0
Answer:
Step-by-step explanation:
3c-3+6c+2= -3c-1 ( 3c+6c =9c) and (-3+2 = -1) so
9c -1 = -3c-1 = so add 3c to both sides to get rid of the 3c on the right side
9c-1 +3c = -3c +3c -1 =
12c-1 = -1 add +1 to both sides
12c-1 +1 = -1 +1
12c=0
c = 0/12
so c= 0

This question deals with linear equations so, with this problem, subsitution is the easiest form of solving.
x + y = 16
8 + y = x
Now you know that x = 8 + y, so replace it in the opposing equation.
8 + y + y = 16 (simplfy)
8 + 2y = 16 (subtract 8 from each side)
2y = 8 (divide each side by 2)
y = 4
plug into other formula
8 + 4 = x
x =12
Answer:
y=4 , x= 12
Step-by-step explanation:
x + y = 16
8 + y = x
8 + y + y = 16 (simplfy)
8 + 2y = 16 (subtract 8 from each side)
2y = 8 (divide each side by 2)
y = 4
8 + 4 = x
x =12
