Multiply dollars / unit * units. It is actually a useful thing to know. Many thing are done using the tools this question requires.
Steve takes home 308.56 dollars. The answer is B.
97 Adult tickets were sold,
97x3=291
300-97=203 student tickets
$291+$203=$494
Answer:
$3
Step-by-step explanation:
Let chocolate pie be x and apple pie be y
Darryl made $38 from 2 chocolate pies and 4 apple pies
That’s
2x + 4y = $38
Kayla made $138 from 14 chocolate pies and 12 apple pies
That’s
14x + 12y = $138
We now have two equations
Equation 1 : 2x + 4y = 38
Equation 2: 14x + 12y = 138
Multiply equation one by 12 and equation 2 by 4 to eliminate apple pie y
We have
12 x 2x + 12 x 4y = 12 x 38
4 x 14x + 4 x 12y = 4 x 138
24x + 48y = 456
56x + 48y = 552
Subtract equation equation two from one
-32x = -96
Divide both sides by -32
x = -96/-32
x = 3
A chocolate pie cost $3
Answer:
C
Step-by-step explanation:
You can just count the number of squares (which I did)
Or you can divide the composite shape into multiple rectangles, find their side lengths, and use the rectangle area formula to find the areas of each of the rectangles and add them all up together.
Answer:
Apply sine theorem:
1.
c/sinC = a/sinA
=> sinC = sinA x (c/a) = sin70 x 28/24 = 1.096 => Invalid ( 1.096 > 1)
=> C is undefined
=> B is undefined
2.
c/sinC = b/sinB
=> sinB = sinc x (b/c) = sin40 x 34/33 = 0.662
=> B = arcsin(0.662) = 41.47 deg
3.
c/sinC = b/sinB
=> sinB = sinC x (b/c) = sin29 x 26/6 = 2.101 => Invalid ( 2.101 > 1)
=> B is undefined
=> A is undefined
4.
c/sinC = a/sinA
=> sinC = sinA x (c/a) = sin28 x 20/16 = 0.587
=> C = arcsin(0.587) = 35.93 deg
Hope this helps!
