The construction cost for the concrete base is estimated at $20 per square foot. Again, if r is the radius of the cylinder, what would be the area of the circular base? Note that the base must have a radius that is 1 foot larger than that of the cylinder. Write an expression for the estimated cost of the base.

Answer:↓↓↓

Step-by-step explanation:

We are given that side AB is congruent to BD. We are also given that side AC is congruent to CD.

We know that side BC and side CB are congruent because of the Reflexive property.

Therefore, ΔABC and ΔDBC are congruent because of SSS Postulate.

The quotient of -7 and y is:

Answer:

[tex] \huge \boxed{ \frac{ - 7}{y} }[/tex]

Given:

The function is

[tex]f(x)=\left(\dfrac{1}{3}\right)^x[/tex]

To find:

The missing values for a, b, and c in the given table.

Solution:

We have,

[tex]f(x)=\left(\dfrac{1}{3}\right)^x[/tex]

At x=-2,

[tex]f(-2)=\left(\dfrac{1}{3}\right)^{-2}[/tex]

[tex]a=\left(3\right)^{2}[/tex]         [tex]\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right][/tex]

[tex]a=9[/tex]

At x=-1,

[tex]f(-1)=\left(\dfrac{1}{3}\right)^{-1}[/tex]

[tex]b=\left(3\right)^{1}[/tex]         [tex]\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right][/tex]

[tex]b=3[/tex]

At x=0,

[tex]f(0)=\left(\dfrac{1}{3}\right)^{0}[/tex]

[tex]c=1[/tex]         [tex]\left[\because a^0=1, a\neq 0\right][/tex]

Therefore, the missing values of a,b and c are 9, 3, and 1 respectively.

Answer:

[tex]2abcosC = 37[/tex]

Step-by-step explanation:

Given

[tex]a^2 + b^2 - 2abcosC = c^2[/tex]

Required

[tex]2abcosC[/tex]

[tex]a^2 + b^2 - 2abcosC = c^2[/tex]

Add [tex]2abcosC[/tex] to both sides

[tex]a^2 + b^2 - 2abcosC+2abcosC = c^2+2abcosC[/tex]

[tex]a^2 + b^2 = c^2+2abcosC[/tex]

Subtract [tex]c^2[/tex] from both sides

[tex]a^2 + b^2 -c^2= c^2 -c^2+2abcosC[/tex]

[tex]a^2 + b^2 -c^2= 2abcosC[/tex]

From the attachment:

[tex]a = 4[/tex] [tex]b = 5[/tex] and [tex]c = 2[/tex]

So, we have:

[tex]4^2 + 5^2 -2^2= 2abcosC[/tex]

[tex]16 + 25 -4= 2abcosC[/tex]

[tex]37= 2abcosC[/tex]

i.e.

[tex]2abcosC = 37[/tex]

Step-by-step explanation:

Answer:  240 liters

=======================================================

Work Shown:

x = capacity of barrel in liters

This value of x is some positive real number. It represents the most amount of water the barrel can hold.

The problem states that the barrel is 2/3 full to start with. This means, we start off with (2/3)x liters of water. Then we subtract off 60 of them to get to 5/12 full, meaning we have (5/12)x liters left.

We can form this equation

(2/3)x - 60 = (5/12)x

Multiply both sides by 12 to clear out the fractions

(2/3)x - 60 = (5/12)x

12*( (2/3)x - 60 ) = 12*(5/12)x

12*(2/3)x - 12*60 = 12*(5/12)x

8x - 720 = 5x

From here we solve for x

8x - 5x = 720

3x = 720

x = 720/3

x = 240

The barrel's full capacity is 240 liters

--------------------------

Check:

2/3 of 240 = (2/3)*240 = 160

The barrel starts off with 160 liters of water inside.

We then use 60 of them to be left with 160-60 = 100 liters

Note how 100/240 = (5*20)/(12*20) = 5/12, showing that 100 liters out of 240 total reduces to the fraction 5/12. In other words, when we say "5/12 full" we mean 100 liters full. This helps confirm we have the right answer.

Answer:

The answer is D.

Step-by-step explanation:

Answer:

length= 710 width= 420

Step-by-step explanation:

As we consider a rectangle we can replace "length" with l and "width" with w so that the perimeter will be:

2l+2w= 2260

With the length as:

l= w+290

The length, substituted into the perimeter is:

2(w+290)+2w=2260

Distribute:

4w+580=2260

Subtract:

4w=1680

Divide:

w=420

To find the length, take the width and add 290:

420+290=710

l=710
