Answer:
96
Step-by-step
the distance from the amusement to jack's home is x (mile, x>0)
jack's family went to the amusement park at: 9 + x/60
On the way home, traffic was bad and they drove 20 mph slower than in the morning⇒ they drove: 60 - 20 = 40 mph
they left the amusement park at: 20 - x/40
have the following equation:
(20 - x/40) - (9+ x/60) = 7
⇔ 4 = x/40 + x/60
⇔ x = 96
so the distance from the amusement park to jack's home is 96 mile
Distance of amusement park from Jack's home = 96 miles
Let the distance from Jackie's house to the amusement park be x.She drove at a speed of 60 mph to get to the amusement park.
Now, formula for time is;Time = distance/speed
Time; t1 = x/60 hours
Now, we are told she spent 7 hours at the park. Thus; t2 = 7 hoursOn her way back home from school, we are told she drove 20 mph slower than her speed in the morning. Thus, speed = 60 - 20 = 40 mphThus; time; t3 = x/40
Now, she left home by 9 am and got home by 8pm same day. This is a total of t = 11 hoursThus;
t1 + t2 + t3 = 11
Plugging in the relevant values;
(x/60) + 7 + (x/40) = 11
Rearrange to get;
(x/60) + (x/40) = 11 - 7
(x/60) + (x/40) = 4
Multiply through by 120 to get
2x + 3x = 480
5x = 480
x = 480/5
x = 96 miles

A carpenter wants to cut a board that is five sixth ft long into pieces that are five sixteenths ft long. The carpenter will use the expression shown to calculate the number of pieces that can be cut from the board. five sixth divided by five sixteenths. Which expression can also be used to calculate the number of pieces that can be cut from the board?
Answer:
N = L/P
8/3 pieces
Step-by-step explanation:
Length of the board = 5/6 ft
A carpenter wants to cut a board that is five sixth ft long into pieces that are five sixteenths ft long.
Length of each piece = 5/16 ft
Number of pieces that can be cut from the board = Total length of board / length of each piece
Let
N = Number of pieces that can be cut from the board
L = Total length of board
P = length of each piece
N = L / P
= 5/6 ÷ 5/16
= 5 / 6 × 16 / 5
= 80 / 30
= 8/3
The number of pieces that can be cut from the board is 8/3

Answer:
(х-4)(х-6)
Step-by-step explanation:
х¹= 4
х²=6
easy
Answer:
(x - 12)(x + 2)
Step-by-step explanation:
Given
x² - 10x - 24
Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 12 and + 2 , since
- 12 × + 2 = - 24 and - 12 + 2 = - 10 , thus
x² - 10x - 24 = (x - 12)(x + 2) ← in factored form

Find the Perimeter of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place
please don't answer if you are wrong
Answer:
38.3
Step-by-step explanation:
The perimeter of the figure can be broken down into the perimeter of 3 sides of the parallelogram, and the perimeter of the semicircle (without its diameter).
The three sides of the parallelogram would be 14+14+4=32.
The perimeter of the semicircle would be 1/2*diameter*pi, which is about 1/2*4*3.14=6.28.
Therefore, the perimeter is 32+6.28=38.3 (to the nearest tenths).
Mr. Wong wants to purchase 12 new smoke detectors for his house. Store A sells each smoke detector for $17 and Store B sells each smoke detector for $24. If Mr. Wong purchases all his smoke detectors at Store A, how much less will he spend than if he purchased all the smoke detectors at Store B?
Answer:
$84
Step-by-step explanation:
so for store A, you would do $17*12 smoke detectors, Which would give you $204. For store B you would do $24*12 smoke detectors. That is $288. Now all you do is 288-204=84. You would save $84 dollars going to store A
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The amount less spend by buying in store A than in store B is $84
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The number of smoke detectors to be purchased.
= 12
Store A:
Cost of one smoke detector = $17
Cost of 12 smoke detectors.
= 12 x 17
= $204
Store B:
Cost of one smoke detector = $24
Cost of 12 smoke detectors.
= 12 x 24
= $288
Now,
The difference between the cost of 12 smoke detectors from store A to store B.
= $288 - $204
= $84
Thus,
The amount less spend by buying in store A than in store B is $84

find the area of the figure above
The area of the shape that is the combination of rectangle and trapezoid will be 71 square inches.
What is the area?The quantity area demonstrates the amount of a sector on a planar or hemispherical cup. Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.
The shape is a combination of a rectangle and a trapezoid.
The area is the summation of the area of the rectangle and the area of the trapezoid. Then we have
Area = Area of the rectangle + Area of the trapezoid
Area = 5 x 9 + (1/2) x (4 + 9) x 4
Area = 45 + 26
Area = 71 square inches
The area of the shape that is the combination of rectangle and trapezoid will be 71 square inches.

Answer:
ans of problem 12 is:
x=65
y=10
Answer:
Step-by-step explanation:
Problem 12:
I think that (2x-y)+60=(2x+y)+40
Because of the Alternate Interior Angles theorem, which places the 40 next to (2x+y) so then you know they are a linear pair. Same can be done for the side with the 60 degree angle. So both sides add up to 180 so they are congruent themselves and you can put them in this format:
(2x-y)+60=(2x+y)+40
-40 -40
We do this to remove the 40 from the right side completely, and whatever you do to one side of the equation you have to do to the other as well so remove 40 from both.
(2x-y)+20=(2x+y)
-2x -2x
Again, we are just trying to find out y right now
-y +20=y
+y +y
20 = 2y
10 = y
Then insert the y into an equation telling us that it is equal to 180 (because we know that from before) to get what x is
(2x-y)+60=180
We can also input our y that we found out was 10 from before:
(2x-10)+60=180
And now we can add up 60 and -10
2x+50=180
Now subtract 50 to both sides
2x=130
And divide both sides by 2
x=75
So x=75 and y=10
