Answer:

213 m^2

Step-by-step explanation:

The surface area for a rectangle prism is given by

A=2(wl+hl+hw)

We know the base is 6 meters by 3.5 m  so l = 6 and width =3.5

The heigth is 9 m

A = 2 ( 6*3.5 + 9* 6 + 9* 3.5)

   = 2 * (21 +54 +31.5)

    = 2*(106.5)

    =213 m^2

Answer:

213 square meters

Answer:

967

Step-by-step explanation:

0.1 x 9670 = 967

The rectangle with a length of 7 units and a width of 4 units, and with one vertex at the origin (0,0), has been successfully created using the segment tool.

Open the drawing tool or any software that allows you to draw shapes and use the segment tool to begin the construction.

First, mark the origin (0,0) on the canvas as one of the vertices of the rectangle.

Now, move the cursor 7 units to the right from the origin along the x-axis and place a point. This point represents the opposite vertex of the rectangle on the right side.

Next, move the cursor 4 units up from the origin along the y-axis and place another point. This point represents the opposite vertex of the rectangle on the top side.

To complete the rectangle, draw straight lines connecting the following points: (0,0) with (7,0), (7,0) with (7,4), (7,4) with (0,4), and finally, (0,4) back to (0,0).

Answer:

202.8

Step-by-step explanation:

The geometric mean of 2 numbers a and b is

[tex]\sqrt{ab}[/tex]

Here a = 30 and mean = 78, thus

[tex]\sqrt{30b}[/tex] = 78

To clear the radical square both sides

([tex]\sqrt{30b}[/tex] )² = 78², that is

30b = 6084 ( divide both sides by 30 )

b = [tex]\frac{6084}{30}[/tex] = 202.8

Answer: An equilateral triangle can NOT be a right triangle.

Step-by-step explanation:

In a right triangle, however, the 3 angles can NOT be congruent. This is because in a right triangle, one angle equals 90 degrees. Therefore, you can't have 3 angles equal 90 degrees.

Answer:

y= 2/3x + 28/3

Step-by-step explanation:

First, write your equation as y=2/3x+b. Plug in your coordinate into the equation, it should look like this: 6=2/3(-5)+b. Multiply 2/3 by -5 to get -10/3. It should look like this: 6= -10/3+b. Add 10/3 to both sides to get your y-intercept of 28/3. Go back to your original equation and plug 28/3 into b. This is your final equation: y= 2/3x + 28/3. Hope this helped!

Answer: 261

Step-by-step explanation:

You use PEMDAS to solve this problem

you first do the Parenthesis (p)

33+6(2+36)

33+6 (38)

We then multiply first (M)

33 + 6(38) - we know that 8 times 6 is 48 ; 6 times 3 is 18 +4 because we brought down the 4 from 48 to 3. which will be equal to 228

The given pyramid has 3 lateral triangular side

The figure is attached below

Base of triangle = 12 unit

Find the perpendicular

By Pythagoras theorem

[tex]hypotenuse^2 = opposite^2 + adjacent^2[/tex]

Therefore,

[tex]opposite^2 = 10^2 - 6^2\\\\opposite^2 = 100 - 36\\\\opposite^2 = 64\\\\opposite = 8[/tex]

Find the lateral surface area of 1 triangle

[tex]\text{ Area of 1 lateral triangle } = \frac{1}{2} \times opposite \times base[/tex]

[tex]\text{ Area of 1 lateral triangle } = \frac{1}{2} \times 8 \times 12\\\\\text{ Area of 1 lateral triangle } = 48[/tex]

Thus, lateral surface area of 3 triangle is:

3 x 48 = 144

Thus lateral area for the pyramid with the equilateral base is 144 square units

Answer:−

-20 √ 7

Step-by-step explanation:

Solution:

Given that,

The costs for going to a dog beach are $7 for 1 dog, and $2 for each  additional dog

Let "x" be the number of dogs

where x is greater  than or equal 1

Cost y is $7 for the first dog and $2 for each of the other dogs

Therefore,

y = 7 + 2(x - 1)

x - 1 means the additional dogs

Therefore,

y = 7 + 2x - 2

y = 2x + 5

Thus the equation is found

C. f (x) = 18 (2/3)x-1

The number of full time employees is 17 and the number of part time employee is 9

Step-by-step explanation:

Step 1 :

Let f represent the number of full time employee and p represent the number of part time employee

Total number of employees = 26

Hence we have f + p = 26

Step 2 :

Wages of full time employee  = $275

Wages of part time employee = $140

Total wages paid by Jeds = $ 5935

Hence we have 275 f + 140 p = 5935

Step 3:

Solving the equations obtained in step 1 and step 2 we have

f + p = 26, Multiplying by 275 = > 275 f + 275 p = 7150

275 f + 140 p = 5935

Subtracting equation 2 from 1 we have

135 p = 1215 => p = 9

Substituting this in f + p = 26 gives, f + 9 = 26

So f = 17

Step 4 :

Answer :

The number of full time employees is 17 and the number of part time employee is 9

x^2-4x+2x-8=0

x^2-2x-8=0

Multiply the equation by 5

5x^2-10x-40=0

To calculate the original price of a wagon on sale at 20% off, divide the sale price of $114 by 0.80, resulting in the original price of $142.50.

To find the original price of the wagon before the 20% sale, we have to determine what $114 represents after the discount has been applied. If $114 is 80% of the original price (100% - 20% = 80%), we need to find 100% by dividing $114 by 0.80:

Original Price = Sale Price / (1 - Discount Percentage)

Original Price = $114 / 0.80

Original Price = $142.50

So, the original price of the wagon before the sale was $142.50.

Answer:

It will take 27.19 years

Step-by-step explanation:

Compound continuous interest can be calculated using the formula:

[tex]A=Pe^{rt}[/tex] , where

∵ Steve deposits $1250 in an account

∴ P = 1250

∵ The account paying 3.4% annual interest compounded continuously

∴ r = 3.4%

- Change it to decimal by dividing it by 100

∴ r = 3.4 ÷ 100 = 0.034

∵ The account balance will reach to $3150.5

∴ A = 3150.5

- Substitute The values of A, P and r in the formula above to find t

∵ ​[tex]3150.5=1250e^{0.034t}[/tex]

- Divide both sides by 1250

∴  ​[tex]2.5204=e^{0.034t}[/tex]

- Insert ㏑ to both sides

∴ ​[tex]ln(2.5204)=ln[e^{0.034t}][/tex]

- Remember that [tex]ln(e^{n})=n[/tex]

∵  [tex]ln(e^{0.034t})=0.034t[/tex]

∴ ​ln(2.5204) = 0.034t

- Divide both sides by 0.034

∴ 27.18875 = t

∴ t ≅ 27.19

It will take 27.19 years

Answer:

46 housewives read all three magazines.

Step-by-step explanation:

Given:

        n(A) = 150

        n(B) = 200

        n(C) = 156

        n(A∩B) = 48

        n(B∩C) = 60

        n(A∩C) = 52

         n(A∪B∪C) = 300

so we know the relation as:

  n(A∪B∪C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C) + n(A∩B∩C)

∴ n(A∩B∩C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C)  - n(A∪B∪C)

                    = 150 + 200+ 156 - 48 - 60 - 52 - 300

                   = 46

Hence the number of housewives that had read all three magazine is 46.
