Answer:
-10.4
Step-by-step explanation:
If k=8
then, -1.3k=-1.3x8 = -10.4
We can l<span>abel the length (l), width (w), and height (h) of the prism and use the </span>formula<span>, SA=2lw+2lh+2hw, because it has '6' faces and to find the </span>surface area put the values in the formula:
SA=2(6)(3)+2(6)(2)+2(2)(3)
SA=36+24+12
SA=72
Answer:
6
Step-by-step explanation:
I would say 6 because 22/4 is 5.5 round that and you get 6 :)
The sum angle of triangle is 180°
The angle of line is 180°
The right angle is 90°
x=180-115
x=65°
y=180-65-90
y=90-65
y=25
Answer:
52 quarters, 42 dimes
Step-by-step explanation:
Let's call the number of quarters q, and the number of dimes d.
q+d=94
0.25q+0.1d=17.20
Subtract q from both sides of the first equation to isolate d:
d=94-q
0.25q+0.1(94-q)=17.20
0.25q+9.4-0.1q=17.20
0.15q=7.8
q=52
d=94-q=42
Hope this helps!
