Answer:
<u>The triangular prism shown has 2 triangular faces and 3 lateral faces.</u>
- The triangles are on the ends, and there are three rectangular faces, which are the "lateral" faces because they're not bases.
<u>The area of one triangular face is 7.5 square millimeters.</u>
- Area of triangle = 1/2 b*h = 1/2* 6*2.5 = 1/2*15 = <u>7.5 square millimeters</u>
<u>The surface area of the triangular prism is 135 square millimeters.</u>
- Lateral face area = the sum of the three lateral faces. = 8*6.5 + 8*2.5 + 6*8 = 120 square millimeters
- Surface area = 2(triangle area) + sum of lateral faces = 2(7.5) + 120 = <u>135 square millimeters</u>
Answer:
Step-by-step explanation:
y = x
Slope of line = 1
Slope of perpendicular to line = -1
Point-slope equation for line of slope -1 through (2,2):
y-2 = -(x-2)
Slope-intercept equation:
y = -x + 4
Standard form:
x+y = 4
Answer:
5/7
Step-by-step explanation:
first of mean to divide
so it really saying x ÷ 3/4 and x = 15/28
15/28 ÷ 3/4 but you cant divide fractions
so we use copy dote flip
copy 15/28
dote ×
flip 4/3
15/28 × 4/3
then cross simplafiy so 4 can go into 28, 7 rimes. and 3 can go into 15, 5 times
5/7
Would it be 2.95? It would be 2.95 If you are trying to get the profit back to 2.5, since you would add all the numbers together (subtract the negatives) and the answer would be .45 which you'd add to 2.5 to equal 2.95
