Guys please I need a lot of help I would deeply appreciate it

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:

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.

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.

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

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

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.

Answer:

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

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

Answer:

Step-by-step explanation:

The largest 6-digit number is:

We 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:

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).
