Answer:

Step-by-step explanation:

The sum of the angles of a triangle should always add up to 180 degrees.

In this problem, they have given us 2 angle measures of the triangle - 53 degrees and 45 degrees. To figure out the third angle, we simply need to figure out how many more degrees we need for reaching the 180 degrees.

I'm just going to do some simple math:

53 + 45 = 98 (sum of the 2 angles)

180 - 98 = 82 (subtracting 180 by the sum of the 2 angles)

However, we have only found the third angle in the triangle. The variable x is for the angle <em>supplementary </em>to the one we just found. Therefore, we must solve the angle measure of the supplementary angle x by doing 180 - 82 which equals 98.

Answers:

interest = $75
balance at maturity = $3075

=============================================================

Explanation:

The simple interest formula is

i = p*r*t

where in this case,

p = 3000 = principal (amount deposited)
r = 0.10 = annual interest rate in decimal form
t = 3/12 = 0.25 = number of years

So,

i = p*r*t

i = 3000*0.10*0.25

i = 75 is the amount of interest earned

This adds onto the initial deposit to get the final balance when the CD matures (ie when you're able to withdraw the money without penalties)

The balance at maturity is p+i = 3000+75 = 3075 dollars

---------------

In short, you deposit $3000 into the CD and have to wait 3 months for the amount to update to $3075.

I need help answering this question

My name is Ann [436]

Answer:

Step-by-step explanation:

JL = JK + KL

84 = 3x+5 + 6x+7

Combine like terms

84 = 9x +12

Subtract 12 from each side

84-12 = 9x+12-12

72 = 9x

Divide by 9

72/9 = 9x/9

8 =x

We want KL

KL = 6x+7

6*8 +7

48+7

Using drawings of rectangular prism, define in your own words, perimeter, area, and volume. Use color pencils to highlight what

yKpoI14uk [10]

This is what a rectangular prism looks like
Now for the definitions:
The perimeter is.... all of the lengths of sides added together.
The area is.... the sides all added together cubed
The volume...... the whole inside. (Think like it’s a shoe box and then you fill the shoe box up with water) that’s the volume
