Answer:
428 square inches
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a prism: 2wl +2lh+2hw
Where w is the width of the prism; l the length; and h the height.
Replacing with the values given:
S (smaller prism) = 2 (4x6) + 2(6x2)+ 2(2x4)=48+24+16= 88 in2
S (larger prism) = 2 (8x10) +2 (10 x5)+2(5x8)= 160+100+80=340in2
Adding both surface areas:
88+340 =428 in2
Feel free to ask for more if needed or if you did not understand something.
Answer: y = 1/5x+5
Step-by-step explanation: Slope intercept form is y = mx+b, where m is the slope, and b is the y intercept. Substitute accordingly.
The answer are:
1.D
2.C
3.A
Explanation is in above pictures.
m<1 =73°
m<2 = 121°
m<3 =59°
m<4 =59°
m<5 =4°
m<6 =73°
m<7 =48°
m<8 =55°
m<9 =4°
