Find m angle C<br> 62 degrees<br> 70 degrees

wlad13 [49]

Answer:

48°

Step-by-step explanation:

..,.............,...........

CDB = ABD( given)

CBD= ADB( given)

Now,

CBD+CDB+C = 180°

70°+62°+ C = 180°

C= 180°-132°

C= 48°

If you deposit $1000 in a savings account with an interest rate of r compounded annually, then the balance in the account after

Sedaia [141]

Answer:

Step-by-step explanation:

Our equation is as follows, B(c)=1000(1+r)^3. We are being asked to manipulate the equation and have it be r equals in order to solve for an interest rate when given a balance B. To solve the equation for the variable r, we must isolate r by completing order of operations or PEMDAS backwards.

SADMEP allows us to undo subtraction, addition, and etc in the correct order. We have no subtraction or addition outside of more complex operations. So we move to multiplication or division.

We divide both sides by 1000.

$\frac{B}{1000} =\frac{1000(1+r)^{3} }{1000}$

We simplify the right side.

$\frac{B}{1000} =(1+r)^{3}$

We need to now undo the exponent of 3 by using the inverse, a cube root.

$\sqrt[3]{\frac{B}{1000}} =\sqrt[3]{(1+r)^{3}}$

We simplify the right side.

$\sqrt[3]{\frac{B}{1000}} =(1+r)$

We subtract 1 to both sides to get r alone.

$-1+\sqrt[3]{\frac{B}{1000}} =r$

For our last step, we simplify the denominator of the root because 10*10*10=1000.

$-1+\frac{\sqrt[3]{b} }{10} =r$

This is answer choice b.

Answer:

Its D. d

Step-by-step explanation:

I believe someone else said this same thing but I'll explain it a bit differently and more in-depth.

There is this common formula that's used a lot, it's r*t=d, rate * time = distance. In this formula, we see that distance is represented as d, so we can assume that in this scenario, the distance will also be represented by d.

When doing math, you're going to wanna make the variables simple and understandable, say you're doing a coin problem with nickels and dimes, you're going to wanna label your variables for nickels "n" and your variables for dimes "d" just so you don't get confused.

Now if you have another problem like this, you don't even have to ask brainly, you can just make an educated guess like this.
