Given the proportional relationship representing the speed, Paul ran faster. The equation for Paul is, y = 7x (Option D).

Proportional relationship between two variables that has a constant rate or unit rate of m, is given as y = mx.

In a graph, the steeper the slope, the larger the constant rate or unit rate.

The graph for Paul is steeper than that of Melinda. Since Melinda's constant speed is 5, therefore, Paul's constant speed cannot be less than 5. It should be more than 5, i.e. 7.

This means that Paul ran at a faster constant speed than Melinda did.

Paul's equation for distance covered over time can be expressed as, y = 7x. (Option D).

well, to get its radius, we can simply get the distance between both points and keeping in mind that the radius is half the diameter, we'll take half of that distance.

We will find the speeds of both persons, the correct option is:

"Ramon rides his bike 3 miles per hour slower than Hector rides his bike."

First, we know that Ramon rides 45 miles in 3 hours, then its speed is:

S = 45mi/3h = 15mi/h

And we know that Hector position is given by:

y = 18x

Where x is time in hours, so his velocity is 18mi/h.

Then we can see that:

So the correct statement is:

"Ramon rides his bike 3 miles per hour slower than Hector rides his bike."

The equation needed to calculate the compound interest is [tex]A = P(1 +\frac{r}{n} )^{nt}[/tex]

The value of the account after ten years is $9347.62 .

If the account is left alone for 20 years, the amount of interest earned is $6942.76

The compound interest formula is represented as follows;

[tex]A = P(1 +\frac{r}{n} )^{nt}[/tex]

where

Therefore,

where

r = 3.7% = 3.7 / 100 = 0.037

n = 1

t = 10

P = $6500

Hence,

[tex]A = 6500(1+\frac{0.037}{1} )^{1(10)}[/tex]

[tex]A = 6500(1.037)^{10}[/tex]

[tex]A = 6500(1.43809495884)[/tex]

A = 9347.61723247

A = $9347.62

The value of the account after ten years is $9347.62

Interest = 9347.62  - 6500 = 2847.62 dollars

When it is 20 years.

r = 3.7% = 3.7 / 100 = 0.037

n = 1

t = 20

P = $6500

Hence,

[tex]A = 6500(1+\frac{0.037}{1} )^{1(20)}[/tex]

[tex]A = 6500(2.06811711064)[/tex]

A = 13442.7612192

A = $13442.76

Interest = 13442.76 - 6500 = 6942.76 dollars

ОА. 449

ОВ. 23°

Ос. 92°

OD. 46°

Step-by-step explanation:

The measure of the angle RST is 23 degrees, option C is correct.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Given that an arc is 46∘

We need to find the measure of the subtending angle inscribed in the circle.

The measure of the angle inscribed in a circle is one-half the measure of the arc it subtends.

The measure of the arc is twice the measure of the subtending inscribed angles.

measure of the angle RST= 1/2 measure of the arc

∠RST=1/2(46)

=23 degrees.

Hence, the measure of the angle RST is 23 degrees, option C is correct.

First you have to find 10% of 340.00 which is 28, so each week he saves 28.00 for his bike. To find how many paychecks he has to recieve you divide 340.00 by 28.00, which is 12.1, since there is a decimal place you have to round it up to 13 because it is a little bit more than 12 paychecks. ;)
