14/19 if you add the amount of nickels and dimes together and then for the denominator just add all of the coins together.

Anna has been adding $30 to her savings account every month. Which model could represent the money in Anna’s savings account (y)

RSB [31]

Y=30x.
Whatever the number of months is you times by 30, the amount she added each month. If she had started with a certain amount you would add that to the equation. Y is the total money in the account.

The sum of the area of 2 circles is 80pi square meters. Find the length of a radius of each circle if one of them is twice as lo

IgorC [24]

80p=pr^2+p(2r)^2
80p=pr^2+4pr^2
80=r^2+4r^2
80=5r^2
16=r^2
r=4 for the smaller circle´s radius, and 8 is the larger circle´s radius.

Have a nice day, I hope this was helpful :D

Prove the sum of two rational numbers is rational where a, b, c, and d are integers and b and d cannot be zero. Fill in the miss

mario62 [17]

Answer:

We conclude that the sum of two rational numbers is rational.

Hence, the fraction will be a rational number. i.e.

$\frac{ad+cb}{bd}$ ∵ b≠0, d≠0, so bd≠0

Step-by-step explanation:

Let a, b, c, and d are integers.

Let a/b and c/d are two rational numbers and b≠0, d≠0

Proving that the sum of two rational numbers is rational.

$\frac{a}{b}+\frac{c}{d}$

As the least common multiplier of b, d: bd

Adjusting fractions based on the LCM

$\frac{a}{b}+\frac{c}{d}=\frac{ad}{bd}+\frac{cb}{db}$

$\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}$

$=\frac{ad+cb}{bd}$

As b≠0, d≠0, so bd≠0

Therefore, we conclude that the sum of two rational numbers is rational.

Hence, the fraction will be a rational number. i.e.

$\frac{ad+cb}{bd}$ ∵ b≠0, d≠0, so bd≠0

Stormer Company reports the following amounts on its statement of cash flow: Net cash provided by operating activities was $37,0

olchik [2.2K]

Answer:

The ending cash balance is $12,800

Step-by-step explanation:

This is an addition and subtraction problem. We begin with the initial cash balance of $6,800. Next we are <u>"provided"</u> cash from various activities of $37,000. Based on the word used we can tell that this means we have to <em>add </em>this to our initial balance like so,

$6,800 + 37,000 = 43,800$

Now our balance is $43,000. Next we are told that Net Cash <u>"used"</u> in investing activities is $13,600 and <u>"used"</u> in financing activities is $17,400. Based on this word we can tell that this money is being <em>subtracted</em> from our balance.

$$43,000 - 13,600 - 17,400 = 12,800$

Finally, we can see that the ending cash balance is $12,800
