solve this question plz​

Answer:

119 in

Step-by-step explanation:

you just have to find the area of each shape individually and add them!

As we can see, we have a square base and 4 triangles. each triangle has the same area because the base is a square and they all have a height of 5. so, the area of a triangle is

[tex]a = \frac{1}{2} bh[/tex]

thus, each triangle is

[tex]a = \frac{1}{2}( 7 \times 5) = \frac{1}{2} (35) = 17.5[/tex]

since we have 4 triangles we can add this together 4 times or multiply by four.

[tex]4 \times 17.5 = 70[/tex]

now, we just need to add the area of the base. the area of a square is

[tex]a = {s}^{2} [/tex]

or

[tex]a = s \times s[/tex]

so, the area of the square is

[tex]a = {7}^{2} [/tex]

or

[tex]a = 7 \times 7[/tex]

which both equal 49.

now, we can add 49 to our sum of the area of our triangles, so

70+49= 119in

Hope this helps!

Step-by-step explanation:

Answer:

See below both methods.

Step-by-step explanation:

9x + 6y = 18

-6x - 6y = -24

Elimination:

9x + 6y = 18

-6x - 6y = -24

Since 6y and -6y add to zero, add the equations to eliminate y and solve for x.

      9x + 6y = 18

(+)   -6x - 6y = -24

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

       3x        = -6

x = -2

Now we need to eliminate y and solve for x. Divide both sides of the second equation by 6 and multiply both sides of the second equation by 9 to get this new equation.

-9x - 9y = -36

Add this new equation to the first original equation to eliminate x.

      9x + 6y = 18

(+)  -9x - 9y = -36

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

            -3y = -18

y = 6

Solution: x = -2; y = 6

Substitution:

9x + 6y = 18

-6x - 6y = -24

Divide both sides of the first equation by 3. Divide both sides of the second equation by -6.

3x + 2y = 6    (Equation 1)

x + y = 4     (Equation 2)

Solve the second equation for x.

x = 4 - y

Substitute 4 - y for x in Equation 1 and solve for y.

3(4 - y) + 2y = 6

12 - 3y + 2y = 6

-y + 12 = 6

-y = -6

y = 6

Now substitute 6 for y in equation 2 and solve for x.

x + 6 = 4

x = -2

Solution: x = -2, y = 6

Answer:

Midpoint is (0, -4)

Step-by-step explanation:

x-coordinate of midpoint = (-7 + 7)/2 = 0/2 = 0

y-coordinate of midpoint = (3 - 11)/2 = -8/2 = -4

Midpoint is (0, -4)

Answer:

(0,-4)

Step-by-step explanation:

(x1 + x2/2,  y1 + y2/2)

(-7 + 7/2 ,  3 + -11/2)

(0/2,  -8/2)

(0,-4)

Answer:

838.08 in³

Step-by-step explanation:

volume of tank = (36×24×24)+(½×3.14×12²×24)

= 20,736 + 5,425.92

= 26,161.92 in³

the remaining water = 27,000 - 26,161.92

= 838.08 in³

Answer:

n = 0 or 10

Step-by-step explanation:

From the question,

Equation of the circle = (x-1)²+(y-5)² = 50 ............... Equation 1

Coordinate of the circle = (6,n)

From the question

x = 6, y = n

Substitute the value of x and y into equation 1

(6-1)²+(n-5)² = 50

5²+(n-5)² = 50

25+(n-5)² = 50

(n-5)² = 50-25

(n-5)² = 25.

Solving for n

n-5 = √(25

n-5 = ±5

Either,

n-5 = -5

n = -5+5

n = 0

or

n-5 = +5

n = 5+5

n = 10

Answer:

n = 3.16

Step-by-step explanation:

Since the point (6, n) lies on the circle then the coordinates of the point make the equation true.

Substitute x = 6 and y = n into the equation

(6 - 1)² + (n - 5)² = 50, that is, expanding using FOIL

5² + n² - 10n + 25= 50 by simplifying

25 + n² - 10n = 50 ( subtracting 50 from both sides and rearrange )

n² - 10n = 0 ← in standard form

n²=10

n = √10

The values of n is 3.16

Answer:

The radius of each base is 4.46 inches.

Step-by-step explanation:

The surface area (SA) of a cylinder is given by:

[tex]SA = 2\pi rh + 2\pi r^{2} = 325[/tex]   (1)

Where:

r: is the radius of each base

h: is the height of the cylinder

Now, the lateral area (LA) is:

[tex]LA = 2\pi rh = 200[/tex]   (2)

Hence, by entering equation (2) into equation (1) we have:

[tex] SA = LA + 2\pi r^{2} [/tex]                  

[tex] 325 = 200 + 2\pi r^{2} [/tex]

[tex] r = \sqrt{\frac{325 - 200}{2\pi}} = 4.46 in [/tex]

Therefore, the radius of each base is 4.46 inches.

I hope it helps you!                                                                

Answer:

B; 1

Step-by-step explanation:

Firstly, we need to find the inverse of the given function

Let us have f(x) as y

To find the inverse, we set out to make x the formula subject

Thus;

y = √(3x + 6)

square both sides

y^2 = 3x + 6

3x = y^2 - 6

x = (y^2 - 6)/3

To write the inverse, replace y by x

So we have the inverse of the function as ;

(x^2 - 6)/3

So what we have to do here is to substitute 3 for x in the inverse

We have this as;

(3^2 -6)/3

(9-6)/3

= 3/3 = 1

Answer:

1 ( option B )

Step-by-step explanation:

The given equation is ,

[tex]\implies f(x) =\sqrt{ 3x + 6 }[/tex]

Now substituting y = f(x) , we have ,

[tex]\implies y=\sqrt{ 3x + 6 }[/tex]

For finding the inverse , Interchange x and y , we have ,

[tex]\implies x =\sqrt{ 3y + 6 }[/tex]

Now solve for y , we have ,

[tex]\implies x ^2=3y + 6 \\\\\implies 3y = x^2-6 \\\\\implies y =\dfrac{x^2-6}{3} [/tex]

Now replace y with f-¹(x) , we have ,

[tex]\implies f^{-1}(x) =\dfrac{x^2-6}{3} [/tex]

Now put x = 3 , we have ,

[tex]\implies f^{-1}(3) =\dfrac{3^2-6}{3}\\\\\implies f^{-1}(3) = \dfrac{9-6}{3}\\\\\implies \underline{\underline{ f^{-1}(3) = 1 }} [/tex]

Answer:

40%

Step-by-step explanation:

well there are 15 candies in the bag, and 6 of them were blue

doing the calculations right, would give you that 40% of the bag is blue candy.

Answer:

6/15

Step-by-step explanation:

Count the amount of blue in the bag.

There are 15 candies all together so the amount of blues are 6while the rest is 15.

So it will be 6 over 15.
