Answer:

1 7/33

Step-by-step explanation:

To find the fraction when the repeating digits start at the decimal point, put the repeating digits over the same number of 9s. Here, your mixed number is ...

$1.\overline{21}=1\frac{21}{99}=1\frac{7}{33}$

If you deposit $10,000 in a bank account that pays 10% interest annually, how much will be in your account after 5 years?

Luba_88 [7]

Interest formula: A=P(1 + r)^t
A = 10000(1 + 0.1)^5
A = 10000(1.01)^5
A = 10000(1.0510100501)
A = $10,510.10

Passes through the points (−4, 2) and (12, 6)?

svlad2 [7]

<u>I'll assume you need to find the equation of the line that passes through those points.</u>

Answer:

$\displaystyle y-2=\frac{1}{4}(x+4)$

Step-by-step explanation:

<u>Equation of a Line:</u>

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The given points are (-4,2) and (12,6), thus:

$\displaystyle y-2=\frac{6-2}{12+4}(x+4)$

Operating:

$\displaystyle y-2=\frac{4}{16}(x+4)$

Simplifying, the equation in point-slope form is:

$\mathbf{\displaystyle y-2=\frac{1}{4}(x+4)}$

a trapezoid with an area of 166.75 in has bases that measure 21in and 8 in find the height of the trapezoid

alisha [4.7K]

Answer:

height = 11.5 in

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = $\frac{1}{2}$ h(a + b)

where h is the height and a, b the bases

here a = 21, b = 8 and A = 166.75, hence

$\frac{1}{2}$ h(21 + 8) = 166.75

Multiply both sides by 2 to eliminate the fraction

29h = 333.5 ( divide both sides by 29 )

h = 11.5 in
