Answer:
Step-by-step explanation:
This tells you to multiply 1 by the number as many times as the exponent says. The example above is 2 raised to the third power (raised to the third power means the exponent is 3). This is equivalent to the multiplication problem below, because there is a 1 multiplied by 2 three times.
Answer:
40
Step-by-step explanation:
Suppose the unknown value is x.
20% "of" x "is" 8
"of" usually means multiply and "is" usually means equals, so:
20% * x = 8
20% = 20/100 = 0.2
0.2x = 8
x = 40
Thus, the answer is 40.
Hope this helps!
Answer:
2. trust me.. i did it before.
Answer:
a = 139.1
b = 56.2
Step-by-step explanation:
A. Reference angle = 68°
Opp = a
Hyp = 150
Therefore:
Sin 68 = opp/hyp
Sin 68 = a/150
150*sin 68 = a
a = 139.1 (nearest tenth)
B. Reference angle = 68°
Adj = b
Hyp = 150
Therefore:
Cos 68 = adj/hyp
Cos 68 = b/150
150*cos 68 = b
b = 56.2 (nearest tenth)
Answer:
8 loaves
Step-by-step explanation:
so each loaf contains 7/8 cups flour
there are 7 loaves
7 ÷ 7/8 = 8
