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?
Answer:
6 minutes
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
please help:)I’m not good at math and need to get this done ASAP
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.

Answer:
y=3/4x+10
Step-by-step explanation:
lts take two points
(-4,7)
(0,10)
so slope is 3/4
so 3/4*-4+b= 7
-3+b=7
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
i used (-4, 7), so the equation would be 7=m(-4)+10
solve for x
-4m=7-10=-3
m=3/4

Given the ordered pairs (-3,-2) and (4,-2), what is the horizontal distance between
the points?
Answer:
7 units apart.
Step-by-step explanation:
Find the difference of the x-values from the two points.
4 - (-3) = 4 + 3 = 7
The horizontal distance from the two points is 7.

HELP! WHY IS THIS TRIANGLE CONGRUENT! EASY PLS HELP
Answer:
D. xz=yz, angle z is shared, wz=wz
Answer:
Side-angle-side postulate
Step-by-step explanation:
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.
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)
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

What's the largest 6-digit multiple of 5 that has all different digits? I'll give Brainliest to anyone who helps.
Answer:
987650Step-by-step explanation:
The largest 6-digit number is:
999999We need all digits different and the last one 0 or 5 because the number is the multiple of 5.
9876 are the first 4 digits and the last two 50 or 45, we'll chose 50 as 45 is smaller.
So the number is:

can somebody help me? Dean is comparing prices on ground beef. Store A is selling 5 pounds of ground beef for $23.49. Store B is selling 8 pounds of ground beef for $36.96.
Which store is offering the better deal on ground beef? Show your work.
Answer:
Step-by-step explanation:
A=$23.49/5lb=$4.70/lb
B=$36.96/8lb=$4.62/lb
So store B is cheaper.
Write the equation of the line that passed through the point (-1,-4) that is perpendicular to the line
2
у -2 +1.
Show all of your work and answer in the text box provided.
Answer:
The line that meets these conditions is y = 1.5x - 2.5
If you want to use fractions, it would be y = 3x/2 - 5/2
Step-by-step explanation:
To get a line perpendicular to y = -(2/3)x + 1, We can start by finding its slope. That's easy enough as a perpendicular slope is the negative reciprocal of the given one. As this has a slope of -2/3, our new slope has to be 3/2, or 1.5
All we need to do then is express that rate of change relative to the given point (-1, -4). We can do this by expanding the classic equation:
Δy = sΔx
We can write that as such:
y - (-4) = 1.5(x - (-1))
y + 4 = 1.5(x + 1)
y + 4 = 1.5x + 1.5
y = 1.5x + 1.5 - 4
y = 1.5x - 2.5
Or if you want to express those numbers as fractions, it would be y = 3x/2 - 5/2.
To make sure the answer's correct, we can simply plug -1 in as the x value, and see if we get y = -4:
y = 3(-1) / 2 - 5/2
y = -3 / 2 - 5 / 2
y = -8 / 2
y = -4
So we know that our answer is correct (assuming that the slope is correct, which it is - a perpendicular line always has the negative reciprocal of the other line's slope).
If you follow a similar approach by drawing a line through point C that is perpendicular to and using the associated defects for ∠A or ∠B instead of ∠C, what are the resulting equations? (Do not go through the complete derivation again, just think about the result you came up with in question 9 and what similar formulas for ∠A or ∠B would look like.)

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?
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
