Answer:

9/15 + 5/15 = 14/15

Step-by-step explanation:

The common denominator of 5 and 3 is 15

5 x 3 = 15, so multiply the numerator by 3 too

you get 9/15

3 x 5 = 15, multiply numerator by 5 too

you get 5/15

alex purchased a 2010 model sedan for $24,000. The dealership offered him a $199/month payment plan for 48 months, at the end of

trapecia [35]

a = prt

a = 24,000 x 0.06 x(48 / 12)(you have to turn months into years)

a = 24,000 x 0.06 x 4

a = $5,760

The payment due is $5,760

One of two complementary angles measures 30 degrees more than three times the other. Find each angle.

Leviafan [203]

The two complementary angles are:

95° and 15°

Step-by-step explanation:

Let x be one angle

then the other angle will be 90-x

As the sum of complementary angles is 90

So,

then according to statement

$x = 3(90-x)+30\\x = 270-3x +30\\x = 300-3x\\x+3x = 300\\4x = 300\\x = \frac{300}[4}\\x = 75\\and\\90 -x = 90 - 75 = 15$

The two complementary angles are:

95° and 15°

Explain the distance formula. Then use it to calculate the distance between A(1,1) and B (7,-7)

crimeas [40]

The distance formula is given by:

$d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }$

We are given two points A and B as

A(1,1) and

B(7,-7)

so we have ,

x1 = 1 , y1=1

x2= 7 and y2=-7

Plugging these in the formula we have:

$d=\sqrt{(7-1)^{2}+(-7-1)^{2} }$

d=√(36+64)

d=√100

d=10

Answer: The distance between A(1,1) and B(7,-7) is 10
