Answer:
49degrees
Step-by-step explanation:
Using the cosine rule
u² = v²+w²-2vwcosU
Substitute the given values
51² = 61²+62²-2(61)(62)cosU
2601 = 3721+3844-7564 cosU
2601 = 7565-7564cosU
-7564cosU = 2601-7565
-7564cosU = -4964
CosU =-4964/-7564
CosU = 0.6563
U = arccos(0.6563)
U = 49degrees(to nearest degree)
carpenter has a board that is 8 feet long. e cuts off two pieces. One piece is 32 feet ug and the other is 2 feet long. How ch of the board is left?
Answer:
2 1/6 feet
Step-by-step explanation:
A carpenter has a board that is 8 feet long. He cuts off two pieces. One piece is 3 1/2 feet long and the other is 2 1/3 feet long. How much of the board is left?
Total length of the board = 8 feet
Piece A = 3 1/2 feet
Piece B = 2 1/3 feet
Piece A + piece B
= 3 1/2 feet + 2 1/3 feet
= 7/2 + 7/3
= (21+14) / 6
= 35/6
= 5 5/6 feet
Length of the board remaining = Total length of the board - length of the two pieces
= 8 feet - 35/6 feet
= (48-35) / 6
= 13/6 feet
= 2 1/6 feet
Length of the board remaining = 2 1/6 feet
Daria makes and sells stuffed toys she uses special fabric to cover a funky to make a number two how much fabric did Daria use to make this number cube
The question is incomplete as the side lengtb of the cube isn't given. Taking the side length to b
be a value, x
Answer:
Step-by-step explanation:
Given that :
The side length = x
To obtain the amount of fabric which would be required for covering the funky, we Obtian the total surface area of the foam. Cube.
Using he relation :
Surface area of a cube = 6 * s² ; the side length s = x
Surface area = 6 * x².
Hypothetically,
Let x = 7 cm

Answer:
933mounths=77years and 9 mounts
Answer:
[tex]77\frac{3}{4}[/tex] years = 933 months
77.75 years = 933 months
Step-by-step explanation:
1 year = 12 months
y = 933 months
[tex]\frac{1}{12}= \frac{y}{933}[/tex]
12 × y = 933 × 1
12y = 933
12y ÷ 12 = 933 ÷ 12
y = 77.75

These are the cost and revenue functions for a line of 24-pound bags of dog food sold by a large distributor:
R(x) = -31.72x2 + 2,030x
C(x) = -126.96x + 26,391
The maximum profit of $ Blank
can be made when the selling price of the dog food is set to $ Blank
per bag.
there are two answers
Answer:
$10,277.32
Step-by-step explanation:
Given the revenue and cost function
R(x) = -31.72x^2 + 2,030x
C(x) = -126.96x + 26,391
The profit function is expressed as;
P(x) = R(x) - C(x)
P(x) = -31.72x^2 + 2,030x-(-126.96x + 26,391)
P(x) = -31.72x^2 + 2,030x+126.96x - 26,391
P(x) = -31.72x^2 + 2,030x+126.96x - 26,391
P(x) = -31.72x^2 + 2,156.96x - 26,391
To have maximum profit, d
The maximum profit dP/dx = 0
dP/dx = -63.44x+2156.96
-63.44x+2156.96=0
63.44x = 2156.96
X = 2156.96/63.44
x = 34
Get the profit
P(34) = -31.72(34)² + 2,156.96(34)- 26,391
P(34) = -36668.32+73336.64-26391
P(34) = 10,277.32
Hence the maximum profit that can be made is $10,277.32

A right triangle has an angle measure of 52.4 degrees. What is the value of 'x', the missing angle?
Answer:
The answer is 37.6 degrees
Step-by-step explanation:
Since a right angle is 90 degrees in total, to find the missing degree subtract 52.4 from 90 to find the value of x.
90-52.4= 37.6 degrees
37.6 degrees is your answer

0.9x+2.3x = -6.4 Find x on both sides of the problem, a little confused... Would we combine the like terms on the left side?
Answer:
-2
Step-by-step explanation:
0.9x+2.3x = -6.4
Add the two values of the left side of the equation together
3.2x = -6.4
Divide both sides of the equation by 3.2
x = -6.4 / 3.2
x = -2
