Answer:
40.0
18%
14.375%
1/250
38
6325
Step-by-step explanation:
Convert the percent to a decimal 4,000%
4000% = 4000/100 = 40.0
Convert the decimal or whole number to a percent.
0.36 * 1/2
= 0.36/2 * 100
= 0.18 * 100
= 18%
Convert the decimal or whole number to a percent.
1.15 * 1/8
= 1.15/8 * 100
= 14.375%
Convert the percent to a reduced fraction, mixed number, or whole number.
0.4%
= 0.4/100
= 1/250
Solve for the portion (in $). Round to hundredths when necessary.
9 1/2% of $400 = 19/2% x 400
= 0.095 x 400
= 38
Solve for the portion. Round to hundredths when necessary.
What number is 253% of 2,500?
253/100 x 2500
= 2.53 x 2500
= 6325

2.)
average velocity=(change in distance)/(change in time), in this case:
v=(549 9/10)/(7 50/60)
v=(5499/10)/(470/60)
v=(5499/10)(60/470)
v=32994/470
v=70.2 km/hr

Make two position functions...
c=15t, and r=120-20(t-1)
c=15t, r=140-20t
They meet when c=r so:
15t=140-20t add 20t to both sides
35t=140 divide both sides by 35
t=4
So they will meet 4 hours after Cindy leaves at 1 pm, thus they meet each other at 5 pm.
check...
c=15(4)=60
r=120-20(4-1)
r=120-20(3)
r=60
1.) Plug x and y to the formula:
4(2) + 1/3(3)^2
2.) Simplify
8 + 1/3(9)
= 8 + 3
= 11
Hope this helped!!!
Answer:
g(x)= 9 cos (x -
) +7
Step-by-step explanation:
What is given is f(x) = g cos (x - pi/2) + 3
Note that the standard form of cosine function is a cos (bx + c) + d
a= amplitude
-c/b = phase shift
d = vertical shift
After moving pi/6 to the left --
x = pi/2 - pi/6 = pi/3
once moving pi/6 left, it is at pi/3
moving 4 units up just means adding 4 + 3, and that equals 7, that would be the vertical shift once applied.
So the equation that represents g(x) is C. 9 cos (x - pi/3) + 7
