Answer:
time left for question C = 12 1/2
Step-by-step explanation:
Total time required for the three quiz= 30 minutes
time spent on question A= 10 9/10 minutes
Time spent on question b= 6 3/5 minutes
Time spent on Question c= Total time required for the three quiz -( time spent on question A+Time spent on question b)
30 - ( 10 9/10 + 6 3/5)
30 -16 (9+ 6/10)
30- 16 15/10( 15/10 = 1 5/10)
30 - 16 + 1 5/10
30 - 17 5/10
From 30, we remove 1 whole number to subtract the fraction from the other number so we have
29 - 17 ( 1 -5/10)
=12 5/10 = 12 1/2

Rewrite this equation in terms of y
2x-3y=22
Answer:
y=[tex]\frac{-22}{3}[/tex]+[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
first subtract 2x
2x-3y=22
-2x -2x
-3y=22-2x
divied by-3
-3y/-3=22-2x/-3y
answer-y=-22/3+2/3x

If using the method of completing the square to solve the quadratic equation x^2-5x-19=0x, which number would have to be added to "complete the square"?
Answer:
25/4 or 6.25
Step-by-step explanation:
Given that the general equation of a quadratic equation is given as
ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.
Hence given x^2-5x-19=0, to complete the square, we add
(-5/2)^2 to both sides following the illustration given.
This is 25/4 or 6.24
Carolyn borrowed $38,500 to pay
for college. If the interest rate is
3.2%, how much total will she
have paid after 10 years?
Answer:
$50820
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.2%/100 = 0.032 per year,
then, solving our equation
I = 38500 × 0.032 × 10 = 12320
I = $ 12,320.00
The simple interest accumulated
on a principal of $ 38,500.00
at a rate of 3.2% per year
for 10 years is $ 12,320.00.

12x + 3y + 4 - 6y - 9
Answer:
12x-3y-5
Step-by-step explanation:
3y-6y=-3y
4-9=-5
Answer:
12x - 3y - 5
Step-by-step explanation:
12x + 3y + 4 - 6y - 9 | Given
12x - 3y + 4 - 9 | Subtract 6y from 3y. It becomes -3y.
12x - 3y - 5 | Add +4 and -9 to get -5.

find sin A and B, cos B and A, and tan B and A
Step-by-step explanation:
[tex] \sin(a) = \frac{7}{25} = 0.28 \\ \sin(b) = \frac{24}{25} = 0.96 \\ \cos(a) = \frac{24}{25} = 0.96 \\ \cos(b) = \frac{7}{25} = 0.28 [/tex]
tan(A)= 7/24= 0.29
tan(B)= 24/7=3.42
A=16.26°
B=73.73°
NEED HELP ASAP GIVING 33 POINTS AND PLZ SHOW WORK DONT DO 7-8
Answer:
1) 1924m²
2) a = (b x h) / 2
(5 x 12) = 60
60 / 2 = 30in²
30in² x 2 = 60in²
area of upper rectangle =
a = l x w
13 x 8 = 104in
area of backer rectangle =
a = l x w
12 x 8 = 96in
60in² + 104 + 96 = 260in²

Please help me. I'm literally failing. Also show your work please.
Area of the rectangle = L X W
Area of the rectangle = 4 X 2
Area of the rectangle = 8 inches
If the drawing is 1/5 of the actual air conditioning unit, then you multiply the reciprocal which is 5 times the area of the drawing. When you want to enlarge it has to be a whole number. When you want to reduce you multiply by a fraction.
So 8 inches X 5 = 40 inches is the actual area of the unit.
