If beaver family one can cut down and 20" tree in 15 minutes and family two can cut down a tree 3 times the size in twice as long how long will it take the second beaver family to cut down a 20" tree
Answer:
10 minutes
Step-by-step explanation:
Beaver family 2 can cut down 60'' (20 x 3) tree in 30 (15 x 2) minutes
In one minute, beaver family 2 would cut down 60/30 = 2'' tree
time to cut down 20'' tree = 20/2 = 10 minutes

Suppose you revolve the plane region completely
about the given line to sweep out a solid of revolution. Describe
the solid and find its surface area in terms of π.
Question: the line x = 4
Answer:
Cylinder56πStep-by-step explanation:
This will result in cylinder with radius of 4 and height of 3.
Total surface area:
S = 2πr² + 2πrh = 2π(4² + 4*3) = 2π*28 = 56πWhich of the following is equivalent to 16 ^3/4
Answer:
83/5
Step-by-step explanation:

Just took the quiz. Have a great day
Help me find the value of X please
Help!!! I will give brainiest
Answer:
48
Step-by-step explanation:
First, get a total of the ration so 3+4=7
Then 112/7=16
So there is 16 times he puts 3 ounces of red and 4 ounces of blue.
3x16 = 48 (red)
4x16 = 64 (blue)
4+48=112
Write an equation in slope-intercept form of the line that passes through the given points.
Answer:
y = 1/3x -3
Step-by-step explanation:
Find the equation of the straight line having a slope root 3 and passing through the point(-1,5)
Given:
Slope of a straight line is [tex]\sqrt{3}[/tex].
The line passing through the point (-1,5).
To find:
The equation of the straight line.
Solution:
The point slope form of a line is:
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope and [tex](x_1,y_1)[/tex] is the point.
The line passing through the point (-1,5) with slope [tex]\sqrt{3}[/tex]. So, the equation of the line is:
[tex]y-5=\sqrt{3}(x-(-1))[/tex]
[tex]y-5=\sqrt{3}(x+1)[/tex]
[tex]y=\sqrt{3}x+\sqrt{3}+5[/tex]
Therefore, the equation of the straight line is [tex]y=\sqrt{3}x+\sqrt{3}+5[/tex].

Anyone help me pls :(
Answer:
1 - G;
2 - R;
3 - E;
4 - D;
5 - T;
6 - J;
7 - O;
8 - B;
Step-by-step explanation:
The formula for calculating the sum of interior angles is ( n − 2 ) * 180 ∘ where n is the number of sides.
1) (4 - 2) * 180 = 360 therefore X + 100 + 118 + 53 = 360 => X = 360 - 100 - 118 - 53 = 89 => X = 89
2) (5 - 2) * 180 = 540 => 90 + 90 + X + 128 + X = 540 => 2*X = 540 - 90 - 90 - 128 = 232 => X = 116
3) (6 - 2) * 180 = 720 => 101 + 126 + X + 96 + 147 + 135 = 720 => X = 720 - 101 - 126 - 96 - 147 - 135 = 115 => X = 115
4) (9 - 2) * 180 = 7 * 180, since all angles are equal the answer is 7 * 180 / 9 = 7 * 20 = 140 => X = 140
5) (5 - 2) * 180 = 540 => 90 + 131 + 102 + X + 145 = 540 => X = 540 - 90 - 131 - 102 - 145 = 72 => X = 72
6) Since the sum of the linear pair angles equal 180, X = 180 - 70 = 110 => X = 110
7) (4 - 2) * 180 = 360; Linear pair angle for 73 is 180 - 73 = 107, that means X + 102 + 39 + 107 = 360 => X = 360 - 102 - 39 - 107 = 112 => X = 112
8) (5 - 2) * 180 = 540; Linear pair angle for 84 is 180 - 84 = 96; Linear pair angle for 79 is 180 - 79 = 101; Linear pair angle for 34 is 180 - 34 = 146; so X + 90 + 96 + 101 + 146 = 540 => X = 540 - 90 - 96 - 101 - 146 = 107 => X = 107

Answer:
[tex]x = \frac{5a-2} {7+5a}\\[/tex]
Step-by-step explanation:
Given the expressions
[tex]x = \frac{5}{9y+5}....1\\y = \frac{5}{5a-2} ...2[/tex]
Substitute 2 into 1
[tex]x = \frac{5}{9(\frac{5}{5a-2} )+5} \\x = \frac{5}{(\frac{45}{5a-2} )+5} \\x = \frac{5}{\frac{45+5(5a-2)}{5a-2} } \\x= \frac{5}{\frac{35+25a}{5a-2} }\\x = \frac{5(5a-2)} {35+25a}\\x = \frac{5(5a-2)} {5(7+5a})\\\\x = \frac{5a-2} {7+5a}\\[/tex]

Payday loans are typically $15 charge with an interest rate of 10% over a 2 wk period which variables in the interest formula are known
Answer:
Time = period of loan
Interest amount = $15
Interest rate = 10%
Step-by-step explanation:
Given:
Charge on loan = interest = $15
Interest rate on loan = 10%
Loan period = 2 weeks
The interest formula is given by the relation :
Interest = Principal * rate * time
Using the interest equation given :
The known variables Given in the question are :
Time = period of loan
Interest amount = $15
Interest rate = 10%

A box in the shape of a rectangular prism has the dimensions shown. What is the length of the interior diagonal of the box? Round to the nearest tent
Enter your answer in the box.
Answer:
141.4 cm
Step-by-step explanation:
Refer to the notations in the attached photo,
AG = d
Using Pythagoras Theorem:
In triangle ABC,
AC
=[tex] \sqrt{ {60}^{2} + {80}^{2} } [/tex]
=[tex] \sqrt{3600 + 6400} [/tex]
=[tex] \sqrt{10000} [/tex]
= 100 cm
∴ AC is 100 cm.
In triangle ACG,
d
=[tex] \sqrt{ {100}^{2} + {100}^{2} } [/tex]
=[tex] \sqrt{10000 + 10000} [/tex]
=[tex] \sqrt{20000} [/tex]
= 141.4 cm (cor. to the nearest tenth)
