Answer:
C. 469 in²
Step-by-step explanation:
The net of the object is a rectangle that is 28 inches long and 14 inches wide. Its area is 392 square inches.
In addition, there are two triangles with base 11 inches and height 7 inches. Together, they have the area of a rectangle 7 by 11, or 77 square inches.
The total surface area of the prism is then ...
(392 + 77) in² = 469 in²
_____
The area of a rectangle is the product of its length and width.
The area of a triangle is half the product of its base and height. So, the area of two identical triangles is the product of their base and height.
_____
<em>Comment on the geometry</em>
This geometry cannot exist as shown. The height of the triangular face is closer to 6.454 inches than to 7 inches.
Answer:
Step-by-step explanation:
See the solution process below:
Explanation:
The slope-intercept form of a linear equation is: y =mx+b
Where m is the slope and b
is the y-intercept value.
We are given the slope in the problem so we can substitute
−5/6 for m in the formula.
And,
(0,6)
is the y-intercept so we can substitute
6
for
b
in the formula giving:
y

Answer:
C: 8.96
Step-by-step explanation:
We know taht ZX is similar to PQ. We can now set up the ratio of 6.4: 5.12
This ratio gives us .8:1
Multiply VX by the ratio to find its corresponding similar side of RQ
(11.2) * .8 = 8.96
$28.20 because you have to multiply 35.25 by 0.20 (20%) which equals 7.05. Then you subtract 35.25 by 7.05 because it is 20% off, which results in the answer of $28.20
