Answer:
5940 cm^3
Step-by-step explanation:
Step one:
given data
Height = 27 cm^3
Area= 220 cm^2
Required
the volume of the box
Step two:
the expression for volume is
V= Area* height
v= 220*27
V= 5940 cm^3
Answer: -32
Step-by-step explanation:
35 (t + 29) = −3(3 − t)
Open the brackets
35t+1015= -9+3t
Collect like terms
35t-3t=-9-1015
32t= -1024
Divide both side by 32
32t/32 = -1024/32
t= -32
$4.55 Add 5.95 and 9.76. You should get 15.45. Then you do 20-15.45=4.55
10) Answer: y = -3x - 7
<u>Step-by-step explanation:</u>
You need to use the Point-Slope formula: y - y₁ = m(x - x₁) ; where (x₁, y₁) is the point and "m" is the slope.
You are given the point (-1, -4). Now you need to find the slope.
You are given the 9x + 3y = 8. Rewrite this in slope-intercept form by solving for y so it is in the form y = mx + b.
9x + 3y = 8
<u>-9x </u> <u> -9x </u>
3y = -9x + 8
<u> ÷3 </u> <u>÷3 </u>
y = -3x + 8/3
↓
m = -3
Parallel lines have the same slope so m = -3
Next, plug in the point (-1, -4) and the slope (-3) into the Point-Slope formula:
y - y₁ = m(x - x₁)
y - (-4) = -3(x - (-1))
y + 4 = -3(x + 1)
y + 4 = -3x - 3
<u> -4 </u> <u> -4 </u>
y = -3x - 7

12) Answer:
<u>Step-by-step explanation:</u>
follow the same steps as #10
Point (3, 1) m = ??
2x + 5y = 7
<u>-2x </u> <u> -2x </u>
5y = -2x + 7
<u> ÷5 </u> <u>÷5 </u>
y =
↓
m =
Parallel lines have the same slope so m =
Next, plug in the point (3, 1) and the slope into the Point-Slope formula:
y - y₁ = m(x - x₁)
y - 1 = (x - 3)
y - 1 = +
