Terrence leaves a $3 tip at a restaurant. If that tip is equal to 15% of his total bill, what is his total bill?
Answers
Answer:
$20
Step-by-step explanation:
To find the total bill, divide the tip amount by 0.15
3/0.15
= 20
So, his total bill was $20
3 ÷ 15%
= 3 ÷ 15/100
= 3 x 100/15
= 300/15
= 20
His total bill is $20
At an average internet speed of 15 mbps, a computer takes 4 minutes to
download an application file. If the speed slows down to 10 mbps, how
long does the computer take to download the file?
Answers
Answer:

Step-by-step explanation:
Speed of net = 15mbps
Time taken = 4min.
Total size of application= 15*60*4= 3600mb
Now speed = 10mbps
Time taken = 3600/10
= 360 sec = 360/6 min
= 6 min

b=10
y= 3/4x+10
if my answer helps please mark as brainliest.
Answer:
y = 3/4 x + 10
Step-by-step explanation:
the b is 10 because y is 10 when x is 0
to find the x, plug in any variable from the chart into the equation y=mx+b

Caden exercises daily by walking on a treadmill. He sets the machine so that he will walk at a steady rate of 3.6 miles per hour.
A. If t represents time in hours and d represents distance in miles write an equation that models the relationship between these variables
B. Use your equation to calculate the distance Caden will walk in 3 of an hour .
C. Use your equation to calculate how long it will take for Caden to walk 4.32 miles
(i have to write sumn for this part)
Answers
Answer:
a) d = 3.6t
b) 10.8 miles
c) 1.2 hours
Step-by-step explanation:
For part a:
Slope of a line: y = mx + b
In this case, the equation would be: d = mt,
where m represents the speed Caden is walking at.
Note: b = 0 in this case because when Caden starts walking on the treadmill, he hasn't really covered any distance yet.
Therefore, plugging in a speed of 3.6 miles per hour, the equation is:
d = 3.6t
For part b:
This is a simple instance of plugging in 3 hours for our t value.
Therefore, d = 3.6 (3)
d = 10.8 miles
For part c:
In this case, we are given that d = 4.32 miles.
Therefore, 4.32 = 3.6t
Dividing both sides by 3.6, we get
t = 1.2 hours

The question is. The Scale of the map is 0:5 in: 20 mi. Find the actual distance corresponding to the map distance. 2 in.
Answers
Answer:
Step-by-step explanation:
I think you mean 0.5 in:20 mi
2 in × (20 mi)/(0.5 in) = 80 mi
2 inches on the map corresponds to 80 miles.
8 miles is the real distance that corresponds to the 2 inch map measurement.
Scaling and actual distance on maps.We can utilize the map's scale to get the actual distance that corresponds to the 2 inch map distance.
The scale is presented as 0:5 in:20 mi, which implies that each 5 inches on the map corresponds to 20 miles in actual travel distance.
Let's establish a ratio to determine the actual distance:
5/2 = 20/x
If we cross-multiply, we obtain:
5x = 2(20)
5x = 40
When we multiply both sides by 5, we get:
x = 40 / 5
x = 8
Therefore, 8 miles is the real distance that corresponds to the 2 inch map measurement.

Answers
Answer:
First and third options are equivalent, second and fourth options are not equivalent.
Step-by-step explanation:
Remember the relation:
[tex]a^n*a^m = a^{n + m}[/tex]
and:
[tex](a^n)^m = a^{n*m}[/tex]
We have the expression:
[tex]7^{1/5}*49^{7/5}[/tex]
We know that 49 = 7*7
Then we can write the above relation as:
[tex]7^{1/5}*49^{7/5} = 7^{1/5}*(7^2)^{7/5}[/tex]
We can use the second relationship from the above ones and write this as:
[tex]7^{1/5}*(7^2)^{7/5} = 7^{1/5}*7^{2*7/5} = 7^{1/5}*7^{14/5}[/tex]
Now we can use the first relationship to get:
[tex]7^{1/5}*7^{14/5} = 7^{1/5 + 14/5} = 7^{15/5} = 7^3 = 343[/tex]
Then:
The first option is equivalent.
The second option is not equivalent
The third option is equivalent.
The fourth option is not equivalent.

First, you know that angle XZW = YZW because they are both 90 degrees.
Next, you know that side WZ = side WZ because of the reflexive property (they are the same side)
Lastly, you know that YZ = XZ because Z is the midpoint meaning it divides the entire thing perfectly in half
You have two sides and the included angle, so it is SAS.

PLS HELP I'll GIVE BRAINLIEST.... A student walks x kilometers (km) along a straight path from point P to point Q. Then the student walks y km along a straight path from point Q to point R. What is the total distance, x + y, in km, that the student walks?
Answers
Answer:
5.5 km
Step-by-step explanation:
P.S - The exact question is -
As from the figure , we can see that
2 square = 1 km
Now,
Number of squares between P and Q = 4
Number of square between Q and R = 7
So,
Total number of squares = Number of squares between P and Q + Number of squares between Q and R
= 4 + 7 = 11
⇒Total number of squares = 11
Now as
2 squares = 1 km
⇒ 1 square = [tex]\frac{1}{2} km[/tex]
⇒11 square = [tex]\frac{11}{2} km = 5.5 km[/tex]
∴ we get
total distance, x + y = 5.5 km
