sorry to bother but it's mr. Mac purchase the kitchen table that was on sale for 20% off the original price of the table was 700 what would be the total amount he saved?
Step-by-step explanation:
Given parameters:
Amount of discount on goods= 20%
Original price of the good = 700
Unknown:
Total amount he saved = ?
Solution:
The total amount he saved will be the value of the discount charged on the original price.
Amount of discount = Percentage discount x original price of goods
Amount of discount = [tex]\frac{20}{100}[/tex] x 700
Amount of discount = 140
The amount saved is 140

The outside temperature decreases by 7F in 3 1 2hours. Part A How would you represent the temperature change as a unit rate? Express your answer as an integer. Part B If the temperature continues to decrease at this rate, what will be the change in temperature after 5 hours?, i got park a just need part b part a is 7°/3.5 hrs = 2°/hr
Answer:
A) 2f / hour
B) 10 f
Step-by-step explanation:
outside temperature decreases by ; 7 F in 3 1/2 hours
a ) represent temperature change as a unit rate
To do this you will need to represent the temperature change per hour
7 f / 3.5 hours
= 7 f / 3.5 = 2 therefore the temperature change as a unit rate = 2f / hour
b) Temperature change after 5 hours
Δ temperature in 5 hours = temperature change per hour * 5
= 2 F * 5 = 10 F
Tiffany Is Filling Her Daughter's Pool With Water From A Hose. She Can Fill The Pool At A Rate Of 1/10 Gallons/Seconds. How Fast Can She Fill Up A 20 Gallon Pool
Answer:
200 seconds
Step-by-step explanation:
Given rate :
Filling rate = 1/10 gallons per second
How fast can a 20 gallon pool be filled ;
Time = size of pool / filling rate
Time = 20 gallons ÷ 1/10 gallon / second
Time = 20 * 10 / 1
Time = 200 seconds
Round 21.068 to the nearest tenth.
Answer:
21.068 rounded to the nearest 10th is 21.1
Step-by-step explanation:
To round a number to the nearest tenth , look at the next place value to the right . If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.
You randomly draw A marble from a bag, record it’s color, and then replace it. You draw a blue marble 11 out of 50 times. What is the experimental probability that the next marble will be blue?
Answer:
since you recorded the first marble then replaced it, you drew 10 blue marbles, so therefore we can predict the next marble you drew, was blue.

An electrician charges $35 per hour, h, plus a $20 fee for driving to your house. Which equation represents to total cost, T, for the electrician to do a job?
Answer:
T= 20 + 35h
Step-by-step explanation:
Giving the following information:
An electrician charges $35 per hour, h, plus a $20 fee for driving to your house.
The $20 fee is a fixed cost. It will remain constant.
The $35 fee acts as a variable cost. It varies with the number of hours required to do the job.
To calculate the total cost (T), we need to use the following formula:
T= 20 + 35h
h= number of hours.

Inspecting a 7th-degree polynomial of 'n' by taking its derivatives
From the given conditions,
2n7+n6+2n4+2n3+2n2
=(n+1)7+(n+1)5+(n+1)4+2(n+1)3+(n+1)2+2(n+1)+1.
2n7+n6+2n4+2n3+2n2
=n7+7n6+21n5+35n4+35n3+21n2+7n+1
+n5+5n4+10n3+10n2+5n+1

+(n2+2n+1)+2(n+1)+1.
n7-6n6-22n5-39n4-49n3-42n2-26n-9=0 .....[1].
Let A(n)=n7-6n6-22n5-39n4-49n3-42n2-26n-9.
For n>2, A(n)<n7-6n6-22n5.
Since A(n)=0,
0<n7-6n6-22n5.
0<n5(n-3+√31)(n-3-√31).
Since n>2, n>3+√31, which means n≥9 .....[2].
Now, to differentiate A(n),
A'(n)=7n6-36n5-110n4-156n3-147n2-84n-26.
A''(n)=42n5-180n4-440n3-468n2-294n-84.
A'''(n)=210n4-720n3-1320n2-936n-294.
A(4)(n)=840n3-2160n2-2640n-936.
A(5)(n)
=2520n2-4320n-2640
=2520{(n-6/7)2-262/147}.
If A(5)(n)=0, n=6/7±√(262/147).
Therefore, A(5)(n)>0 for n≥3.
Although n≥9 according to [2], I try inspecting A(n) for n≥10.
When n≥10, A(4)(n) increases monotonously.
A(4)(10)=840000-216000-26400-936>0.
Therefore, A(4)(n)>0 for n≥10.
And when n≥10, A'''(n) increases monotonously.
A'''(10)=2100000-720000-132000-9360-294>0.
Therefore, A'''(n)>0 for n≥10.
And when n≥10, A''(n) increases monotonously.
A''(10)=4200000-1800000-440000-46800-2940-84>0.
Therefore, A''(n)>0 for n≥10.
And when n≥10, A'(n) increases monotonously.
A'(10)
=7000000-3600000-1100000-156000-14700-840-26>0.
Therefore, A'(n)>0 for n≥10.
And when n≥10, A(n) increases monotonously.
A(10)
=107-6000000-2200000-390000-49000-4200-260-9>0.
Therefore, A(n)>0 for n≥10 .....[3].
From [2] and [3], A(n)=0 only when 9≤n<10.
In consequence, n=9.

Rewrite `-3x+2y=12` in slope intercept form and show your steps. Then identify the slope and y-intercept.
Answer:
Slope-Intercept Form: [tex]y=\frac{3}{2}x+6[/tex]
Slope: [tex]\frac{3}{2}[/tex]
Y-Intercept: [tex](0,6)[/tex]
Step-by-step explanation:
STEP 1: Add 3x to both sides of the equation.
[tex]2y=12+3x[/tex]
STEP 2: Divide each term by 2 and simplify.
[tex]y=\frac{3x}{2} +6[/tex]
STEP 3: Reorder terms.

Solve for m:
5m - 3= 7m - 13
Answer:
The answer is m = 5
Answer:
m = 5
Step-by-step explanation:
5m - 3= 7m - 13
-2m-3=-13 ........ subtract 7m from both sides
-2m = -10 ......... add 3 to both sides
m = 5 ........ divide both sides by 2 and you get 5

Ok but fr help.. Assuming only the lengths of the sides of a triangle are given, how can you determine if the triangle has a right angle?
Answer:
If you take the 2 smallest sides and put it in the pythagreon theorem to get the other side length.
Step-by-step explanation:
So if you have a triangle with side lengths, 3, 4, and 5, you can use the exact equation below.
[tex] {3}^{2} + {4}^{2} = {5}^{2} [/tex]
Because this is true, then the triangle does have a right angle.
Last month we had twelve days of either corn or carrots in the cafeteria for lunch. There were six more days of corn than carrots. How many days did we have corn?
Answer:
9 days
Step-by-step explanation:
Given that:
Days whereby there was either corn or carrot = 12 days
There are 6 more days of corn than carrot.
How many days did we have corn?
Let Number of days we had carrot = x
Hence,
Number of days we had corn = x + 6
Total number of days we had either of the two = 12
Hence,
x + (x + 6) = 12
2x + 6 = 12
2x = 12 - 6
2x = 6
x = 6/2
x = 3
Number of days we had corn = x + 6 ;
Hence,
3 + 6 = 9

Which is the best estimate of the distance between the point (-25, 10) and the origin?
O 8 units
w
O 15 units
O 23 units
O 27 units
The best estimate of distance between the point and the origin is 15 units. this is your answer.
The distance between the point (-25, 10) and the origin is 27units
Distance between two pointsThe formula for calculating the distance between two points is expressed as:
D = √x² + y² (since the other coordinate is an origin)
Given the coordinate points (-25, 10) and (0, 0)
Substitute
D = √(-25)² + 10²
D = √625 + 100
D = √725
D = 27unts
Hence the distance between the point (-25, 10) and the origin is 27units

Step-by-step explanation:
Bring everything with x over to one side and everything else to the other.
ax-bx=-8
Factor out x.
x(a-b)=-8
Divide both sides by a-b
x=-8/(a-b)
