Answer:
Q = 108°
R = 72°
Step-by-step explanation:
Quadrilateral means this is a four-sided shape. Parallelogram means that both sets of opposite side are parallel, so all the angles are either equal or add up to 180° (supplementary)
The order of the letters matters bc PQRS means that you go along an edge from P to Q, but you have to go thru the middle of the shape to get from P to R. So P and Q add up to 180°.
P + Q = 180°
72° + Q = 180°
Q = 108°
Opposite from each other, across the middle of the shape, P and R are equal.
P = R = 72°
We need 75 quarts of 3% butterfat milk. How much of 2% and 5% do we need to mix? (t = 2% and f = 5%)
A) t + f = 75
B) .02 t + .05 f = (.03 * 75)
B) .02 t + .05 f = 2.25
Solving for t and f:
t = 50 quarts of 2 % and
f = 25 quarts of 5%
Double-Check
50 * .02 = 1 quart of buttermilk
25 * .05 = 1.25 quarts of buttermilk
2.25 quarts divided by 75 quarts = 3 % buttermilk
Y=mx+b, m= slope, b= y intercept, plug in. Y=3x+5
Answer:
square
Step-by-step explanation:
8 + 0.4 + 0.07 + 0.008 is your answer. But all you had to do is separate your numbers with working on the biggest number to the smallest number.
