Answer:
THE AREA OF THE FACES THAT ARE NOT BASES
Step-by-step explanation:
I just took the quiz this is the correct answer
Area of paralellogram=legnth times height
l=legnth
h=height
area=96
lh=96
h is 4 less than l
h=-4+l
sub
l(-4+l)=96
-4l+l^2=96
minus 96 both sides
l^2-4l-96=0
factor
(l-12)(x+8)=0
set to zero
l-12=0
l=12
l+8=0
l=-8, imossible, legnth cannot be negative, disreagard this soultion
legnth=12cm
Answer:
You can buy 7 additional donuts
Step-by-step explanation:
$0.50 times 7 is $3.50 and $7.50 plus $3.50 is $11 dollars so you would be able to get 7 additional donuts
Answer:
Step-by-step explanation:
<h3>Equation of the blue line:</h3>
since the line is horizontal and passes <u>-</u><u>2</u> the equation of the blue line should be
<h3>Equation of the red line:</h3>
remember The form of equation of a line
where m is slope of the line and b is the y-intercept we can clearly see that the red line crosses y-axis at (0,-3) therefore b=-3
to figure out m we can consider the following formula:
from the graph we acquire ∆y=1 and ∆x=2
thus substitute:
so we have figured out m and b
therefore our equation of blue line is
our given options are in standard form so
move -3 to left hand side and change its sign:
cross multiplication:
move 6 to right hand side and x to left hand side and change its sign
multiply both sides by -1:
hence, our system of linear equation is
Answer:4 dozens of video games would cost $1956
Step-by-step explanation:
An electronic store prices 3 dozen video games at a total of 1467. A dozen of video games is 12. Therefore, the total number of video games whose cost is 1467 is 12 × 3 = 36
if each video game costs the same amount, then the cost of one video game would be
1467/36 = $40.75
The total number of video games in 4 dozens of video game would be
4 × 12 = 48
Therefore, the total cost of 48 video games would be
48 × 40.75 = $1956
