Answer:

Step-by-step explanation:

Since the pyramids are similar, the scale factor will be 3. So the height of the small pyramid is 6.3/3=2.1. The volume will be (1/3)*(2.1)*(2.3)^2=3.70

What are the points if the slope is 4 and the point is (1,-1)

kherson [118]

The points if the slope is 4 and the point is (1,-1) are (1,-1) and (2, 3)

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change, slope or gradient

<h3>How to determine the points?</h3>

The given parameters are:

Slope = 4

Point = (1, -1)

The slope of 4 means that as x changes by 1, the value of y changes by 4

This means that, we have:

(x + 1, y + 4)

Substitute the known values in the above equation

(1 + 1, -1 + 4)

Evaluate

(2, 3)

Hence, the points if the slope is 4 and the point is (1,-1) are (1,-1) and (2, 3)

3 5⁄7 + 1 9⁄14 = What is the answer if the answer is wrong I will come and haunt you

slega [8]

Answer:

$5 \frac{5}{14}$

Step-by-step explanation:

$3 \frac{5}{7} + 1 \frac{9}{14}$

Turn them into improper fractions

$\frac{26}{7} + \frac{23}{14}$

$\frac{2}{2} \times \frac{26}{7} + \frac{23}{14}$

$\frac{52 + 23}{14}$

$\frac{75}{14}$

Turn it into a mixed fraction

$5 \frac{5}{14}$

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.

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