Answer:

25 chords

Step-by-step explanation:

First, set up the ratio 40:8.

Now, make a proportion.

\frac{40}{8}=\frac{x}{5}

This proportion will give you x=25, so your answer is 25.

Hope this helps! Have a great day! :)

Can anyone help me with this
stepladder [879]

Answer:

D

Step-by-step explanation

I'd say it's PQR and TSR cause they match up in terms of the order of vertexes, and then you've got the angles of P and T that are in the middle of PR and TR, which are equal, and the sides PQ and TS. The angles are in between the sides.

Ariane borrows $300 on a 5−year loan. She is charged 5% simple interest per year. How much interest is she charged for 5 years?
AnnyKZ [126]

Answer:

Interest = $75

Total to pay back = $375

Step-by-step explanation:

The total amount she will have to pay back is found by the formula:

= Amount borrowed * (1 + rate * years)

= 300 * ( 1 + 5% * 5)

= $375

The interest is therefore:

= Amount to be paid back - Amount borrowed

= 375 - 300

= $75

Hey can you help me fast I am at a 83 and I need to get to a 90 on this.
jeyben [28]

Answer:

2/5

Step-by-step explanation:

First by looking, you have a slope going upward to the right so it is a positive slope.

Two points on the line that seem to go directly through the grid at the intersection points are ( -60, -90) and ( 40, -50).

Slope is Rise (y axis) over the Run (x axis).  The numbers above have x first and y second.

So the rise is the total distance between -90 and -50 which is 40.

The run is the total distance between 40 and -60 which is a total of 100.

It takes 40 units to get back to the 0 mark on the x axis and the another 60 units to get to the -60 point.

So you slop is 40/100.  You can simplify this down to 4/10 or even further to give you 2/5.
