Answer:
x = 70.53 degrees
Step-by-step explanation:
equation:
cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]
⇒ cos-1 x = [tex]\frac{4}{12}[/tex]
⇒ cos-1 x = 0.33
⇒ x = 70.528
round to the nearest tenth:
⇒ 70.53

Answer:
Step-by-step explain to solve for the maximum area, the first derivative should be solved and equate it to zero, then solve for x.
A = 37x - x^2
dA / dx = 37 - 2x
equate dA / dx = 0
0 = 37 - 2x
2x = 37
x = 37 / 2
x = 18.5 ft
so the maximum area is
A = 37x - x^2
A = 37( 18.5) - 18.5^2
A = 342.25 sq ft
so the answer is letter B

x + 122 + 32 = 180
x + 154 = 180
x = 180 - 154
x = 26
Answer:

Answer:
m<BCF=140°
Step-by-step explanation:
first find m<BCD
m<BCD=180-50-90
m<BCD=40°.
to find m<BCF, we can do 180-m<BCD, since m<BCD and m<BCF add up to 180° (they form a straight angle)
180-m<BCD=m<BCF
180-40=m<BCF
m<BCF=140°

Solving the formula P = 2L + 2W for W is NOT equivalent to which equation?
Answers
Answer:
3rd one
Step-by-step explanation:

w = P - 2l / 2
Therefore, the equivalent equation to the given equation is [tex]w=P-\frac{1(L)}{2}[/tex].
What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equation is
[tex]2L + 2w = P\\\\2(L+w)=P\\\\L+w=\frac{1}{2}P\\\\w=\frac{1}{2}P-L\\\\w=\frac{P-2L}{2}\\\\w=P-\frac{1}{2}L[/tex]

Ms. Wang and her class are selling bags of cookies to raise money for a field trip.
Each bag weighs 140 grams and has 6 cookies.
Each cookie has the same amount of dough that weighs 14 grams.
Each cookie has the same amount of candy
If a bag of candy has 20 grams of Candy, how many bags of candy does the class need to make 18 cookies?
Answers
Answer:
9 bags of candy
Step-by-step explanation:
6 cookies at 14 grams each = 84 grams meaning the remaining grams of the 140 have to be the weight of the candy which = 56 grams (140-84). To find out how much candy is in one cookie divide 56 by 6 which = 9.33333. You then divide 20 by 9.3333 which = 2.14 (rounded to nearest 10th). Since you can get just over 2 cookies worth of candy per bag you only need half the number of cookies in bags of candy (9 bags)
