A school group has $140 to spend. Write and solve an inequality that represents the cost to rent the main hall, where h represents the number of hours the group can rent the room.
Answers
Answer:
a. 15h + 40 ≤ 140
b. h ≤ 6.6
Note: The question is missing a table. The table is shown in the attachment below.
Step-by-step explanation:
a. The school group has $140 to spend, and so can only spend an amount less than or equal to $140 when renting the main hall.
The cost of renting the main includes an hourly rate of $15 and a set-up fee of $40.
Let h represent the number of hours the group can rent the hall.
Cost of renting the main hall, C is given by:
15h + 40 ≤ 140
b. Solution of the inequality:
15h + 40 ≤ 140
15h ≤ 140 - 40
15h ≤ 100
h ≤ 100/15
h ≤ 6.6
Therefore, the main hall can only be rented for a maximum of 6.6 hours or less

Expressions A, E and F have positive products. This implies that, there are 3 expressions with a positive product.
The perimeter of a 6-sided figure is 67.74 meters. Two of the sides have the same length. The sum of the other 4 side lengths is 36.4 meters. About how long is each of the same-side lengths?
Answers
Each of the same-side lengths is 15.67.
What is perimeter?It is the sum of length of the sides used to made the given figure.
We have been given that the perimeter of a 6-sided figure is 67.74 meters. Two of the sides have the same length. And the sum of the other 4 side lengths is 36.4 meters.
Let the same side be a.
The perimeter of the figure = 6 x side
The perimeter of the figure = 2a + 36.4
67.74 = 2a + 36.4
2a = 67.74 - 36.4
2a = 31.34
a =15.67
Therefore, each of the same-side lengths is 15.67.

Find the slope of the line perpendicular to 2x+3y=8
Answers
Answer:
Marissa.
Step-by-step explanation:
To find perpendicular slope you basically take the slope of the given line and reverse whatever sign it had previously. (If it was negative, it would become positive. If it was positive it would become negative.)
By doing -A/B it make the previous slope negative.
Brandon only flipped the fraction which would just result in the slope being slightly steeper, or in this case, less steep than the previous line, rather than making it perpendicular.

Answer:
2x + y = -7
Step-by-step explanation:
Standard form is Ax + By = C
A represents the coefficient with x
B represents the coefficient with y
C represents the constants
1 - Rewrite to make it easier to work it out
y - 3 = -2 ( x + 5 )
2 - Distribute
y - 3 = -2x - 10
3 - Get the variables on one side and the constants on the other
y - 3 = -2x - 10
+ 2x + 2x
2x + y - 3 = -10
+ 3 + 3
2x + y = -7

6. Talayah bought two journals. The second
journal cost $12 more than the price of
the first journal. If she spent $30 on both,
how much was the second journal?
A. $12
B. $16
C. $20
D. $28
Answers
Answer:
C. $20
Step-by-step explanation:
Lets make our equation. "x" will be our first journal, and "4/5x + 12" will be our second journal. So our equation is: x + 4/5x + 12 = 30
Subtract 12 from each side: x + 4/5x = 18
Combine like terms : 1 4/5 x = 18
Divide each side by 1 4/5 : x = 10
Plug in x for the journals-
1 = 10
2 = 4/5 of 10 = 8 + 12 = $20

Find the area of the shaded region. Express your answer in terms of π.
Answers
Answer:
335.115
Step-by-step explanation:
First you find the area of the circles to do that you do pi times radius squared
For the top square do 3.14(pi)time 3²=28.26
For the middle square do 3.14 times 4.5²=63.585
For the bottom square do 3.14 times 6²=113.04
Now find the area of the entire thing do 18×12+9+6+3=18×30=540
Finally do 540-the area of the squares 28.26-63.585-113.04= 335.115
So the shaded region is 335.115

Answer:
C. x + 8 = 3
Step-by-step explanation:
x + 8 = 3
x + 8 - 8 = 3 - 8 ( so do the same thing you do on both the left and right side )
x = -5
So C is correct but you can always say 3 - 8 to figure out that the answer in c is the right one.
