Answer:

108 miles in 18 hours

Step-by-step explanation:

Remember the formula:

Distance = rate x time

From the first sentence,

“I can ride my bike 72 miles in 12 hours.”

we know that the distance = 72 miles and the time = 12 hours.

By putting the known values in the formula,

72 miles = rate x 12 hours

You can find your rate, which essentially is the speed you are moving at,

Lets say rate = r

72 = 12r

r = 72/12

r = 6

So your rate is 6 miles per hour.

Now we have this part of the question:

If you go 6 miles per hour, then how far will you go in 18 hours?

Remember the formula

d = rt

Plug in the values:

d = 18 x 6

d = 108 miles

Answer:

The graph of function g is the graph of function f shifted 6 units up.

Step-by-step explanation:

Given

$f(x) = 2^x$

$g(x) =2^x + 6$

Required

Compare g(x) to f(x)

Substitute $f(x) = 2^x$ in $g(x) =2^x + 6$

$g(x) = f(x) + 6$

This implies that f(x) is shifted 6 units upward to give g(x)

Linear equation: -1

Anika [276]

Answer:

The right answer is:

the addition property of equality and then the division property of equality

Step-by-step explanation:

Given equation and steps to solve it are:

Step 1: –3x – 5 = 13

Step 2: –3x = 18

Step 3: x = –6

In step two, -5 has to be removed from left hand side of the equation so additional property of equality will be used i.e. adding 5 on both sides

Similarly in the third step, to remove -3 with x , division property of equality will be used i.e. dividing both sides by -3

Hence,

The right answer is:

the addition property of equality and then the division property of equality

Solve this equation: 4y + 228 = 352. A. y = 31 B. y = – 31 C. y = 3 D. y = 145

V125BC [204]

To let the variable alone you can follow these steps: 1) subtract 228 from both sides 2) divide both sides by 4. This is the solution: 1) 4y + 228 - 228 = 352 - 228 => 2) 4y = 124 => 3) (4y)/4 = 124/4 => 4) y = 31. Then, the answer is the option A. y = 31.

One member of the debate team is going to be chosen president. each member is equally likely to be chosen. the probability that

inessss [21]

Let
x-------> the probability that a boy is chosen
B------> number of boys in the debate team
G------> number of girls in the debate team

we know that
B+G=20-----> G=20-B-----> equation 1
probability that a boy is chosen=number of boys in the debate team/total of people
so
x=B/20-------> equation 2

the probability that a girl is chosen is 2/3 the probability that a boy is chosen
probability that a girl is chosen=(2/3)*x
probability that a girl is chosen=G/20
(2/3)*x=G/20-----> equation 3
substitute equation 1 in equation 3
(2/3)*x=[20-B]/20----> equation 4

resolve the equations system
x=B/20
(2/3)*x=[20-B]/20

using a graph tool
see the attached figure
the solution is
x=0.6
B=12
G=20-12-----> G=8

number of boys in the debate team is 12
number of girls in the debate team is 8
the probability that a boy is chosen is 0.6 ----> 60%
the probability that a girl is chosen is 0.6*(2/3)----> 0.4---> 40%

the answer is
number of girls in the debate team is 8
