Answer:
It’s b 3 with an exponent or 2 times 5
Step-by-step explanation:
Answer
148cm^2
Explanation
A cuboid has equal width and length as it’s base is a square. So w or l = root 30
Since the volume of a cuboid is
Length • width • height
And we know length and width when multiplied are 30
30 • height = 120
Therefore height = 4
Now for surface area it’s
2 • h • l + 2 • h • w + 2 • l • w
2 • 4 • root 30 + 2 • 4 • root30 + 2 • 30 = 60 + 16root30 = 148~cm^2
Q1.
The initial value of the linear relationship is -2 /y-intercept/
Answer: -2.
Q2. /<span>The slope of a
line is a <span>rate of change./</span></span>
x = -1 and y = 10
x = 1 and y = 9
(10 - 9)/(-1 - 1) = -1/2
<span>Answer: A. -1/2.
</span>Q3.
y = 3.50x + 300
<span>Answer: Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.
</span>Q4.
y = mx + b
(0; 10); (2; 20)
m = (20 - 10)/(2 - 0) = 10/2 = 5
(0; 10) ⇒ b = 10
y = 5x + 10
<span>Answer: Shanna had $10 in her piggy bank and earned $5 each week in allowance.
</span>Q5. /<span>The slope of a
line is a <span>rate of change./
</span></span> y = 150x + 1,400
Answer: 150.
