Answer:
1.) 6
2.) -1
3.) 36
4.) 1/3
5.) 90
Step-by-step explanation:
1.) -12/a
-12/a -> -12/2
=6
2.) a+ (-b)
a+(-b) -> 2+(-3)
=-1
3.) 3a (12-2b)
3a(12-2b) -> 3(2) (12-2x3)
6(12-6)
6(6)
=36
4.) 2a-c/b

Steve reads 20 pages of his graphic novel per hour. If the book has 200 pages and he reads for d hours, which expression shows the number of pages he has left to read after reading for d hours?
Answer:
200-20d
Step-by-step explanation:
If he reads 20 pages per hour, you would multiply it with d, as d is equal to an unknown number of hours, and to show the number of pages left after reading for d hours, you would subtract it
A principal records the lunch choices for 7th grade for a day. Of the 160 students, 21 brought their lunch from home, 103 purchased lunches, and 36 brought a lunch from home and purchased an ice cream.
Are the lunch choices equally as likely? Justify your answer by calculating the probability of each lunch choice.
Answer:
All of the lunch choices are not equally as likely.
Step-by-step explanation:
Of the 160 students:
21 brought lunch from home = 21/160 = 0.13125
103 purchased lunch = 103/160 = 0.64375
36 lunch + ice cream = 36/160 = 0.225
The probability = what type of lunch a student brings / student population

Answer:
60 [tex]ft^{2}[/tex]
Step-by-step explanation:
To find the surface area, you need to find the area of all the shapes that make up the pyramid and add them all together.
The area of the square is simply 36 [tex]ft^{2}[/tex], as it is the length times itself (6x6)
To find the area of a triangle, it is bh/2, where b = base, and h = height. The height is 4 ft, and the base is 6 ft as the length of the square is the same as the base of the triangle. (4x6)/2 = 12.
The area of one of the triangles is 12, and they are all identical and there is 4 of them, so 12 x 4 = 48.
Add that to the area of the square:
48 + 12 = 60

Answer:
(3, 2)
Step-by-step explanation:
y = 3x - 7
2x + 5y = 16
Solve for x:
2x + 5(3x - 7) = 16
2x + 15x - 35 = 16
17x = 51
x = 3
Solve for y:
y = 3(3) - 7
y = 9 - 7
y = 2

You are using a hose to fill up your backyard swimming pool on a hot day. Water flows out of the hose at a rate of 6 gallons per minute. In the equation below, m is the number of minutes the hose has been running, and g is the number of gallons of water in the pool.
The relationship between these two variables can be expressed by the following equation: g = 6m
Identify the dependent and independent variables.
Answer:
dependent variable = g = gallons of water in pool
independent variable = m
g is dependent on the value of m

Triangle weighs 3 grams Circle weighs 6 grams. Write an equation to represent each hanger. Let x represent the pentagon.
Answer:
Answer: 3.75 g
Step-by-step explanation:
Assume the weight of the square is x.
The hanger is in balance so the left side is equal to the right side.
Equation therefore is:
Triangle + Square + 3 * circle = 5* square + circle
3 + x + (3 * 6) = 5x + 6
3 + x + 18 = 5x + 6
5x - x = 3 + 18 - 6
4x = 15
x = 15/4
x = 3.75 g

Answer:
1. 7
2. 97
Step-by-step explanation:
3 is the bottom length of the triangle and its the same for both sides so that leaves us with the square in the middle, since the bottom of the triangle is 3 and the top of the trapezoid is 10 we subtract 3 from 10 and get 7 and since a square has all identical sides we know the area of the square is 7 x 7 = 49 + 48 (which is the two triangles) = 97

Step-by-step explanation:
Area of a triangle
The area of a triangle can be calculated using the formula
A = bh/2 where b = base length and h = height
Finding the area by plugging in the values of the height and base length
Looking at the triangle we can tell that the base length is 8 and the height is 10. ( so b = 8 and h = 10 )
So we have A = bh/2
==> plug in b = 8 and h = 10
A = (8)(10)/2
==> multiply 8 and 10
A = 80/2
==> divide 80 by 2
A = 40
