Mallory has three dollars in her wallet if this is 10% of her monthly allowance what is her monthly allowance

Answers

Answer:

$30.

Step-by-step explanation:

Definition:

Allowance: A regular sum of money that is given by a parent or guardian to a child in each month.

Solution:

We can use the following formula to find the total amount of Mallory's monthly allowance:

$\sf \textsf{ Percentage of allowance saved} * \textsf{ Total allowance = Amount saved}$

In this case, we know that Mallory has saved $3, which is 10% of her monthly allowance.

Plugging these values into the formula, we get:

$\sf 10\% * \textsf{ Amount saved} = 3$

$\sf 0.10 * \textsf{ Amount saved} = 3$

Divide both sides by 0.10.

$\sf \textsf{ Amount saved} = (3)/(0.10)$

$\sf \textsf{ Amount saved} = 30$

Therefore, Mallory's monthly allowance is $30.

What is the radius of a circle with an area of 32.1 square feet?

Answers

So we want to know the radius of the circle that has area A=32.1 ft^2. The formula for the area of a circle is A=pi*r^2. So to get the radius we must first divide both sides by pi and then take the square root. So, r^2=A/pi=10.2229 and the square root is= r= sqrt 10.2229 = 3.197 ft

To find the mass in grams, multiply the number of kilograms by the unit rate, 1,000 grams per kilogram.

Explanation: To find the mass in grams, you multiply the number of kilograms by the unit rate, which is 1,000 grams per kilogram. So, to convert 12 kilograms to grams, you would multiply 12 by 1,000. The mass of the package in grams would be 12,000 grams.

How to find the slope of a line if it says 2x+Y=15 what do i do??

Answers

First, you have to convert it to slope intercept form, which is $y=mx+b$ )

$2x+y-2x=15-2x$
$y=-2x+15$

Knowing this, you can easily find the slope. In slope intercept form, the "m" or the coefficient of "x," is the slope.

$m=-2$

Therefore, your slope is -2.
