Robert takes out a loan for $7200 at a 4.3% rate for 2 years. What is the total paid amount at the end of the loan?
Answer:
$7819.20
Step-by-step explanation:
total paid amount at the end of the loan= loan taken + interest on the loan
loan taken = $7200
interest on the loan can be determined using this formula
Interest = principal x intrest rate x time
7200 x 0.043 x 2 = $619.20
total paid amount at the end of the loan= $7200 + $619.20 = $7819.20

PLEASE HELP -> Write a slope-intercept equation for a line that passes through (-4, 7.3) and (0,7.3).
The slope-intercept equation for the line is
(Use integers or decimals for any numbers in the equation.)
Answer:
y=7.3
Step-by-step explanation:
with the two points, you could find the point-slope equation...
y−7.3=0⋅(x+4)
this is y=7.3
there is no slope-intercept equation for this because both of the points are on the same horizontal line. Equations that are written in slope-intercept form are never horizontal or vertical.

For the function, f(x) =1/4 x - 2, find x if f(x) = -1.
Answer:
x = 4Step-by-step explanation:
Given function
f(x) =1/4 x - 2Find x if f(x) = -1
1/4x - 2 = - 11/4x = 2 - 11/4x = 1x = 1*4x = 4Answer:
x=4
Step-by-step explanation:
f(x) =1/4 x - 2 when f(x) = -1.
-1=1/4x-2
-1+2=1/4 x
1×4=x
x=4

The measures of the angles of a quadrilateral in degrees are 70, 95, and 136. Determine the measure of the missing angle.
Answer:
let missing Angle be x
x+70+95+136=360 sum of interior angle of quadrilateral is 360
x+301=360
x=360-301=59°
therefore the measure of the missing angle is 59°

4x + 8 - 9x = -17 what is x\
and the x has to be the same for each
Answer:
x = 5
Step-by-step explanation:
4x + 8 - 9x = -17
combine like terms:
-5x = -25
divide both sides of the equation by -5:
x = 5
Answer:
x=5
Step-by-step explanation:
4x-9x+8=-17
-5x+8=-17
subtract 8 from both sides and you get:
-5x=25
divide 5 from both sides, and you get x=5! :)

Brad read that you should drink at least 2 quarts of water a day. Yesterday he drank 3 cups in the morning, 1 quart in the afternoon, and 1 pint in the evening. Did Brad drink at least 2 quarts of water? Explain.
Answer:
yes he drank 2.25 quarts
Step-by-step explanation:
convert the cups to quarts
1 cup = 0.25 quarts
3 cups x 0.25 = 0.75 quarts
convert the pints to quarts
1 pint = 0.5 quarts
add all the amount of water drank together
0.75 quarts + 1 quart + 0.5 quarts = 2.25 quarts
