Answer:

25/10

Step-by-step explanation:

Make the fractions improper by multiplying the whole number by the denominator and then adding the numerator (if this makes sense).

This makes 5x10=50+3=53/10

Do the same for the second fraction. 2x5=10+4=14/5

Then make the denominators the same, and in this case all you need to do is multiply both sides of 14/5 by 2, so that makes 28/10.

Now, just take it away.

53/10-28/10=25/10, which can be then simplified into 2 1/2 or 5/2.

A central angle in a circle with a radius of 3 cm intercepts an arc with a length of 6 cm what is the measure of the central ang

Fiesta28 [93]

Answer:

$114.59\°$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

In this problem we have

$r=3\ cm$

substitute

$C=2\pi (3)=6 \pi\ cm$

Remember that

$360\°$ subtends the arc length of the complete circle

by proportion

Find the measure of the central angle for an arc length of $6\ cm$

$\frac{360}{6\pi } \frac{degrees}{cm} =\frac{x}{6} \frac{degrees}{cm} \\ \\x=6*360/(6\pi )\\\\ x=114.59\°$

liq [111]

Answer:

$\$31.25$

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

Let

y-------> the interest earned on an account

x------> the balance in the account

step 1

Find the constant k of proportionality

For $x=\$200,y=\$12.50$

$k=y/x$

substitute the values

$k=12.50/200=0.0625$

The equation is

$y=0.0625x$

step 2

Find the amount of interest earned on an account with a balance of $500

For $x=\$500$ substitute in the equation and solve for y

$y=0.0625(500)=\$31.25$
