Answer:
The first ones area is 35 cm squared
The third ones area is 32 cm squared
Step-by-step explanation:
A=1/2H (B1+B2)
35=2.5(8+6)
32=2(7+9)
Answer:
y=-1/100x+6 or y=-1x+600
Step-by-step explanation:
6 inches is the Y intercept (600,0) if measuring by 1/100 or (6,0)
Since the wax is melting, the slope is going to be negative
y=mx+6 or y=mx+600 either is fine and would yield the same results
y=-.01x+6, y=1/100x+6 or y=-1x+600
To explainn why 6 and 600 are both fine, 6 is measuring with full inches while the 600 is measuring with .01 inches. One graph will be full numbers while the other will be decimals.
Answer:
Only choices C and D are solutions
Step-by-step explanation:
6x + 3y = -15
y = -2x - 5
6x + 3y = -15
6x + 3(-2x - 5) = -15
6x - 6x - 15 = -15
0 = 0
Since 0 = 0 is a true statement, both equations of this system are the same equation and represent a single line on the coordinate plane.
We need to check each choice in just one equation.
Let's use the second equation.
y = -2x - 5
A.
(2, 7)
7 = -2(2) - 5
7 = -4 - 5
7 = -9 False
Not a solution
B.
(5, 0)
0 = -2(5) - 5
0 = -10 - 5
0 = -15 False
Not a solution
C.
(-3, 1)
1 = -2(-3) - 5
1 = 6 - 5
1 = 1 True
Solution
D.
-13 = -2(4) - 5
-13 = -8 - 5
-13 = -13 True
Solution
Answer: Only choices C and D are solutions
Answer:
its less than
Step-by-step explanation
-8/15 equals -0.53 which means -0.51 is less than
The solution of the given inequality is:
x ≤ 15.24
<h3>
How to solve the inequality?</h3>
We know that the maximum that she can spend on gasoline is the 12% of $400.
That is:
(12%/100%)*$400 = 0.12*$400 = $48
Now, we know that each gallon of gas costs $3.15, then if x is the number of gallons of gas that she buys, we have the inequality:
x*$3.15 ≤ $48
To solve the inequality, we need to divide both sides by $3.15
x ≤ $48/$3.15
x ≤ 15.24
So the maximum number of gallons of gasoline that she can buy is 15 gallons (actually a little more).
