You are going to visit your aunt who lives 25 miles away . You have already traveled 7.7 miles. What percentage of the trip is still ahead of you?
The percentage of the trip that is still ahead of you is 69.2%.
What is the percentage?The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
You are going to visit your aunt who lives 25 miles away. You have already traveled 7.7 miles.
The percentage of the trip that is still ahead of you is calculated as,
P = [(25 - 7.7) / 25] x 100
P = (17.3 / 25) x 100
P = 0.692 x 100
P = 69.2%

Find the exponential function that contains the points (2,36) and (3,108).
Answer:
[tex]f(x) = 4\times (3)^{x}[/tex].
Step-by-step explanation:
Exponential functions are in the form [tex]f(x) = a\, \left(b^{x}\right)[/tex], where [tex]a[/tex] and [tex]b[/tex] are constants with [tex]b > 0[/tex].
In this question, the function should satisfy that [tex]f(2) = 36[/tex] and [tex]f(3) = 108[/tex]. Hence, constants [tex]a[/tex] and [tex]b[/tex] should ensure that:
[tex]a \cdot b^2 = f(2) = 36[/tex], and
[tex]a \cdot b^3 = 108[/tex].
Rewrite the left-hand side of the second equation: [tex]a \cdot b^{3} = a \cdot b^2 \cdot b[/tex].
Substitute the first equation [tex]a \cdot b^{2} = 36[/tex] into the second:
[tex]a \cdot b^2 \cdot b = 108[/tex].
[tex]36\, b = 108[/tex].
[tex]\displaystyle b = \frac{108}{36} = 3[/tex].
Substitute [tex]b = 3[/tex] into either equation (for example, the first equation) and solve for [tex]a[/tex]:
[tex]a \cdot 3^2 = 36[/tex].
[tex]a = 4[/tex].
Hence, the exponential function [tex]f(x) = a\cdot b^{x} = 4 \times (3)^{x}[/tex] should satisfy the requirements of this question.
Which of the following represents the total surface area?
O 844 in.²
O 548 in.²
O 296 in.²
O 210 in.²
Answer:
Step-by-step explanation:
It is the 2nd one.
2nd one. makes more scence
Answer:
844 in.²
Step-by-step explanation:
Find the area of all the sides, and add them up
(20 x 7.4) x 2 = 296
(20 x 10) x 2 = 400
(10 x 7.4) x 2 = 148
296 + 400 + 148 = 844 in.²

there are 640 students in one school. How many boys are there if it is known that 1/4 of the number of girls is equal to one sixth of the number of boys?
Answer:
960
Step-by-step explanation:
You have to figure out what 1/4th of 640 is, which is 160.
It says that number is 1/6th of boys, so you multiply by the inverse.
160x6 = 960
well since all of the girls = 4/6ths of the boys that would mean 24/24girls=16/24boys
16/24 is 66.666666666667% of 24/24
66.666666666667% of 640 is426.666666667 but in my head i would round up so:
Approximately
427 boys and 213 girls.
