1)
8.75 * 20 = 175
8 * 20 = 160
175 - 160 = 15
He'd make $15 more working at the amusement park.
2)
Semi-monthly means twice a month. So, her company is going from 2 to 4 pay periods.
3280 * 2 = 6560 (is what she makes per month)
6560/4 (because 4 weeks in a month) = 1640
OR (An alternative method.)
3280/2 = 1640
She'll be paid $1640 per week.
4)
105,000/12 (12 months in 1 year) = 8750 (He makes this per month)
8750 * 2 = 17500
He makes 17500 semi monthly
8750 /4 = 2187.5
2187.5 * 2 (because bi-weekly) = 4375
He makes 4375 bi-weekly
8750/4 = 2187.5
He makes 2187.5 every week
Dont forget to add the dollar signs. I didnt add them, but you need to. If you need me to add them I can.
Answer:
Total Surface Area: A = 88 square cm
Step-by-step explanation:
Volume V = 48 cubic cm
So this cuboidal box is actually a rectangular prism.
V = L * W* H
L = length, W = breadth, H= height
With L: W : H = 3: 2: 1
L:W = 3: 2
W: H = 2: 1
L/W = 3/2, L = (3/2)*W
W/H = 2/1 , W = 2*H
L = (3/2)*(2H) = 3H
So : V = L * W * H = (3H) * (2H) * H = 6 * H^3
48 = 6 * H^3
48/6 = 8 = H^3
H = cube-root(8) = 2 cm
so ...
W = 2*H = 2*2 = 4 cm
L = (3/2)*W = (3/2)* 4 = 6 cm
Total Surface Area: A = 2*LW + 2*LH + 2*WH
A = 2*(6 * 4) + 2*(6 * 2) + 2*(4 * 2)
A = 2*24 + 2*12 + 2*8
A = 48 + 24 + 16
A = 48 + 40
A = 88 square cm
I did this in class ! * CORRECT ME IF IM WRONG*
12x8=?+4+4= your answer , your welcome
The slope is 2 because remember, y= mx+b
m= slope
the slope is always multiplied by x
