Answer:

Total surface area = 132 square feet

Step-by-step explanation:

Surface area of the triangular prism = Area of the triangular bases + Area of the lateral rectangular sides

Area of the triangular surface = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                                 = [tex]\frac{1}{2}\times 5\times 4[/tex]

                                                 = 10 square feet

Area of the rectangular side with dimensions 5ft by 7ft,

Area = 5 × 7 = 35 square feet

Area of the rectangular side with dimensions 7ft by 4ft,

Area = 7 × 4 = 28 square feet

Area of the rectangular side with dimensions 7ft by 7ft,

Area = 7 × 7 = 49 square feet

Total surface area = 2(10) + 35 + 28 + 49

                               = 132 square feet

Answer:

B) 4y - 2 - 3y = 6

Step-by-step explanation:

x = 4y - 2 Substitute this into the second solution

x - 3y = 6

4y - 2 - 3y = 6

Answer:

Step-by-step explanation:

hi, use y=mx+b to help solve

the equation is y= 6x+30, 6 being the cost per t-shirt and 30 being the fee

substitute x for the values on the left in the table. for example, y=0x+30 would give the total cost of 0 t-shirts 30 dollars

for some reson i cant see it

Answer:

(x,y) = (2,3)

Step-by-step explanation:

y=5x-7                  (i)

-3x-2y= -12          

-(3x+2y)= -12

3x+2y= 12            (ii)

By putting the value of y from (i) in (ii)

3x+2(5x-7)=12

3x+10x-14=12

13x=12+14

13x= 26

x = [tex]\frac{26}{13}[/tex]

x= 2

By putting the value of x in (i)

y= 5(2)-7

y= 10-7

y= 3

(x,y) = (2,3)

Answer:

x = 7

y = 4

Step-by-step explanation:

Measure of all the angles on right side triangle are equal. So, it is an equilateral triangle.

Therefore,

5y - 4 = 3x - 5..... (1)

Next, measure of two angles in the left side triangle are same, so it is an isosceles triangle.

Therefore,

y + 12 = 3x - 5......(2)

(By isosceles triangle property)

From equations (1) & (2)

5y - 4 = y + 12

5y - y = 12 + 4

4y = 16

y = 16/4

y = 4

Plug y = 4 in equation (2), we find:

4 + 12 = 3x - 5

16 + 5 = 3x

21 = 3x

x = 21/3

x = 7

16 is the answer I did it and got it right.

n must be 0, since x ⁿ = 1 for all positive, real x if n = 0. So the answer is A.

Answer:

length = 20

Width = 14

Step-by-step explanation:

x - y = 6   -------------------(I)

x + y = 34 ------------------(II)

Add equation (I) & (II). So y will be eliminated and you can find the value of x

(I)         x - y = 6

(II)       x + y = 34  {Now add}

        2x      =  40      {Divide both sides by 2}

             x   = 40/2

x = 20

Plugin x = 20 in equation(II)

20 +y = 34

       y = 34 -20

y = 14

Answer:

128 m squared

Step-by-step explanation:

Area of rhombus is

[tex] \frac{p \times q}{2} [/tex]

where p and q is the diagonal.

Rhombus's diagonals are equal to each other and bisect each other so just multiply the diagonal of one side by 2. and the other by 2 as well.

The horizontal diagonal is

8x2=16

The vertical diagonal is

8x2=16.

Plug those into the formula

[tex] \frac{16 \times 16}{2} [/tex]

[tex] \frac{256}{2} [/tex]

[tex]128[/tex]

Answer:

128m2

Step-by-step explanation:

8x8=64

64/2=32

32x4=128

The equation is y - 18 + y + x = 180

The figure that completes the question is added as an attachment

From the attached figure, we have the angles to be

y - 18, y and x

The sum of angles in a triangle is 180

This can be represented mathematically, as:

Sum of angles in a triangle = 180

Substitute the known values in the above equation, so, we have the following representation

y - 18 + y + x = 180

Hence, the required equation of the angles is y - 18 + y + x = 180
