Answer:
(7) 1482 in³
(8) 216 yd³
Step-by-step explanation:
Formulas
<u>Volume</u><u> </u><u>of</u><u> </u><u>prism</u>
= base × height/length
<u>Area of parallelogram</u>
= base × height
<u>Area of trapezium</u>
= (upper base + lower base) × height ÷ 2
(7)
Area of the base = 19×6
= 114 in²
Length = 13 in
Volume = 144×13
= <u>1482 </u><u>in</u><u>³</u>
(8)
Area of the base = (11+7)×12÷2
= 108 yd²
Length = 2 yd
Volume = 108×2
= <u>216 yd³</u>

Answer:
b i think
Step-by-step explanation:
According to Wikipedia: "<span>In mathematics, a function
is a relation between a set of inputs and a set of permissible outputs
with the property that each input is related to exactly one output."
So based of this we need to look for a set where one of the x values or the y values is the same, and the other number is different.
Answer:
B.
(1,4) and (1,1) both have the same x, but different y!

Answer:
x>9
Step-by-step explanation:
Tamika already has $55, which will stay the same independent of how much time passes. Since she deposits $5 per week, we can assign weeks a variable x. The amount of money in her account after x weeks is equal to 55+5x. If she must save over $100, we can create an inequality to solve for how many weeks must pass: 55+5x>100.
The question also asks to solve the inequality:
- 55+5x>100
- 5x>100-55 (Subtract 55 from each side)
- 5x>45
- x>9 (Divide each side by 5)
This solution tells us that Tamika must save for more than nine weeks to have more than $100 in her account.
lmk if i made an error, hope this helps!!
