Answer:
One hour after starting
Step-by-step explanation:
Let Teri walk at a rate of 2 miles per hour in time , t + 0.5, since it is 30 minutes ahead and 30 minutes = 0.5 hours, the distance he moves is d = 2(t + 0.5). Also, since Cindy moves at a rate of 3 miles per hour, and starts at time t, the distance d' she moves is d' = 3t.
Now, when they catch each other, the distance moved is the same.
So, d = d'
2(t + 0.5) = 3t
expanding the brackets, we have
2t + 2 × 0.5 = 3t
2t + 1 = 3t
collecting like terms, we have
3t - 2t = 1
simplifying, we have
t = 1
So, Cindy will catch Teri one hour after starting.

A bicycle wheel has a diameter of 28 inches. Which expression can be used to describe the circumference of the wheel as it relates to diameter?
Given:
The diameter of a bicycle wheel is 28 inches.
To find:
The circumference of the wheel as it relates to diameter.
Solution:
We have,
Diameter: [tex]d=28\text{ inches}[/tex]
We know that,
Radius: [tex]r=\dfrac{d}{2}[/tex]
[tex]r=\dfrac{28}{2}\text{ inches}[/tex]
The circumference of a circle is
[tex]C=2\pi r[/tex]
Putting [tex]r=\dfrac{28}{2}[/tex], we get
[tex]C=2\times \pi \times \dfrac{28}{2}[/tex]
[tex]C=28\times \pi[/tex]
Therefore, the correct option is (H).

A plumber charges his customers $25.70 per hour, h, plus a $54.50
service fee. On Tuesday, he earns $118.75 for fixing Mrs. Goodwill's
sink.
Mrs. Goodwill also hires an electrician to repair several damaged
outlets in her home. The electrician charges $35.22 for each individual
outlet repair, r, plus a $62 service fee.
If the electrician charges Mrs. Goodwill a total of $167.66, which
equation shows how to determine the number of individual outlet
repairs correctly?
A. 35.22-62r = 167.66
B. 35.22r -62 = 167.66
C. 35.22 +62r = 167.66
D. 35.22r + 62 = 167.66
Answer:
D
Step-by-step explanation:
multiplying 35.22 with r since this amount is charged for every repair and then adding 62 since that is the additional fee

Which of the following graphs correctly graph y=4^x
(PICS BELOW!!!) (HURRY)
Answer:
Thus, the 2nd or lower graph represents the graph of [tex]y\:=\:4^x[/tex].
The correct graph is also attached below.
Step-by-step explanation:
Given the function
[tex]y\:=\:4^x[/tex]
Let us determine the y-intercept by setting x=0, and then determining the corresponding y-value.
now substituting x = 0 in the function
[tex]y=\:4^0\:[/tex]
Apply the rule: [tex]a^0=1,\:a\ne \:0[/tex]
[tex]y = 1[/tex]
Thus, the y-intercept is (0, 1)
Now, if we closely observe the 2nd graph or lower graph, the y-intercept of the lower graph is (0, 1)
Thus, the 2nd or lower graph represents the graph of [tex]y\:=\:4^x[/tex].
The correct graph is also attached below.
How many \frac{1}{3} 3 1 inch cubes does it take to fill a box with width 22 \frac{2}{3} 3 2 inches, length 33 \frac{1}{3} 3 1 inches, and height 22 \frac{1}{3} 3 1 inches?
Answer:
560Step-by-step explanation:
First we need to find the volume of the cube;
Volume = Length * Width * height
Given;
Length = 3 1/3 in
Width = 2 2/3 in
Height = 2 1/3 in
Volume = 3 1/3 * 2 2/3 * 2 1/3
Volume = 10/3 * 8/3 * 7/3
Volume = 560/3 in^3
To know thw amount of 1/3 in^3 it takes to fill the box, we will take the ratio of the volume to the unit volume;
Ratio = 560/3÷1/3
Ratio = 560/3 * 3/1
Ratio = 560
Hence it will take 560 1/3 in^3 to fill a box with that volume

Answer:
15°Step-by-step explanation:
Let the smaller angle be xThen the other angle is 5xSum of acute angles equals to 90°
x + 5x = 90°6x = 90°x = 90°/6x = 15°The smallest angle is 15°
HELP I GIVE POINTS FOR THIS and brainliest Use the recursive formula f(n) = 0.4 ⋅ f(n − 1) + 11 to determine the 2nd term if f(1) = 4.
Answer:
The second term is 12.6
Step-by-step explanation:
Let us solve the question
∵ The recursive formula f(n) = 0.4 ⋅ f(n − 1) + 11
∵ f(1) = 4
→ To find the 2nd term, sunstitute n by 2
∵ n = 2
∴ f(2) = 0.4 · f(2 - 1) + 11
∴ f(2) = 0.4 · f(1) + 11
→ Substitute f(1) by 4
∵ f(2) = 0.4 · 4 + 11
→ Simplify the formula
∴ f(2) = 1.6 + 11
∴ f(2) = 12.6
∴ The second term is 12.6
The graph shows a journey in a car Which of the statements most likely describes the journey at the portion of the graph labeled J?
Distance
(mi)
hiszen
Time (hr)
The car continues its journey because the portion shows a linear function
The car is waiting at the starting point because the portion shows a constant function
The car is traveling the same distance per unit of time because the portion shows a linear function away from the starting point.
The car stops at a distance away from the starting point because the portion shows a constant function away from the starting point.
Answer:
D) The car stops at a distance from the starting point because the portion shows a constant function away from the starting point.
Step-by-step explanation:
For this case, the first thing you should keep in mind is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
For the portion of the chart labeled J we have:
The time increases
The distance is the same
We have then that the speed is zero.
Therefore, the car is stopped at a distance far from the starting point.

Solve A= Iw for I.
I need help please
Answer:
After solving the given formula for l, we get
l = A/w
Step-by-step explanation:
Given formula is:
A = lw
The given formula is the formula for area of a rectangle.
Solving for a particular variable means that the variable has to be isolated on one side of the equation.
In order to solve,
Dividing both sides by w
[tex]\frac{A}{w} = \frac{lw}{w}\\l = \frac{A}{w}[/tex]
Hence,
After solving the given formula for l, we get
l = A/w
