Rachel can walk 2.5 miles in 40 minutes at this rate how far can she walk in one hour
3.75 miles
Explination~first you would start by finding out how many miles she walks in 1 minute by dividing 2.5 by 402,5 ÷ 40 =
0.0625
Then you would times that by 60, because 60 minutes equals 1 hour0.0625 × 60 =
3.75
So, Rachel can walk 3.75 miles in 1 hour :))------------------------------------------------------------------------Hope I helped!!

I HAVE TWO QUESTIONS PLEASE PLEAAASEEE HELP!!!
Answer:
The second one is 70 for sure since 80% of 70 is 56.
The first one would just be 17r. You cannot get a number answer since time formula involves three variables and there is only 1 given variable.
Answer:
a)17 min(i am not sure)
b) 80/100 = 56/x
cross multiply
5600 = 80x
x = 5600/80
x = 70
ans 70 miles
Find the measures of the exterior angles.
Answer:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. (Non-adjacent interior angles may also be referred to as remote interior angles.) FACTS: An exterior ∠ is equal to the addition of the two Δ angles not right next to it.
Determine if the graph shows two quantities that vary directly. If possible, determine the constant of proportionality using the formula K = y/x
Answer:
Option C is correct option.
Step-by-step explanation:
We need to find k constant of proportionality
In the graph below let us take the values of x and y
x=150 , y=50
x=300, y=100
x=450, y=150
Now finding k using the formula: [tex]k=\frac{y}{x}[/tex]
Putting values of x and y to find k
For x=150 , y=50 k = 50/150, k =1/3
For x=300, y=100 , k=100/300 , k=1/3
For x=450, y=150, k= 150/450 , k=1/3
Since for values of x and y, k = 1/3 is constant so, the graph shows two quantities that vary directly.
So, Option C is correct option.

Answer:
f(6)=2
f(2)=4
f(0)=7
f(5)=1.5
f(x)=1 x=4
Step-by-step explanation:
f(x)=y.The numbers represent the x values. As you are plugging in a number for x. Just look at the graph on the x-axis to get the y-values.

Answer:
LB=12ft
Step-by-step explanation:
Rewrite with only sin x and cos x.
cos 2x + sin x
1 + 3 sin x
1 + 3 sin2x
1 - 2 sin2x + sin x
1 + 2 sin2x + sin x
Answer:
[tex]cos(2x)+sin(x)=1-2\,sin^2(x)+sin(x)[/tex]
which agrees with the third option listed.
Step-by-step explanation:
I believe you meant to write the answer with only sin(x).
Use the double angle identity for the cos(2x) as shown below:
[tex]cos(2x) = cos^2(x)- sin^2(x)\\since \\cos^2(x) = 1-sin^2(x)\\then:\\cos(2x) = 1-sin^2(x)- sin^2(x)\\cos(2x)=1 - 2\,sin^2(x)[/tex]
Now we use this identity in the original expression to get:
[tex]cos(2x)+sin(x)=1-2\,sin^2(x)+sin(x)[/tex]
which agrees with the third option listed.

PLEASE HELP I AM STRUGGLING
Answer:
y=-2x+2
Step-by-step explanation:
the slope intercept form is y=mx+b
slope - to find the slope from 2 point you do (y2-y1)/(x2-x1) so it would be
(14-2)/(-6-0). which out simplify to -2.
y-intercept - the y-intercept is given in one of the points (0,2).

Answer:
Jamie is 56 years old and savannah is 24 years old
Step-by-step explanation:
60 split in half 30, then savannah is 16 years younger than jamie so u subtract 16 from 30 and u get 14, then u add the 16 to the other 30 and get 46. Then you add 10 to each of those numbers.

If a car travels 180 miles in 4 hours, how many miles would it go in 6?
Answer:
270
Step-by-step explanation:
First, to find how far the car will go in one hour, you do 180 divided by 4. We already know that the car drives at a constant rate. If you do 180 divided by 4, you get 45. Then you multiply 45 by the amount of hours (6) to get 270
