Answer:

a) 56 square units

Step-by-step explanation:

x = 3 (width - w)

y = 5 (base - b)

h = 7 (length and height - l and h)

  • Area of a rectangle: l*w
  • Area of a triangle: 1/2*b*h

For the triangles:

Area of a triangle: 1/2*b*h

A = 1/2 * 5 * 7

A = 1/2 * 35

A = 17.5

*Since there are two triangles, it would be 17.5 * 2 = 35

For the rectangle:

Area of a rectangle: l*w

A = 7 * 3

A = 21

Now, we add them together:

A = 35 + 21

A = 56 square units

Therefore, the area of the parallelogram is 56 square units

Hope this helps!

Answer:

Option A. 56 square units

Step-by-step explanation:

Using the formula:

A = \frac{1}{2}(a+b) h  or  A = \frac{a+b}{2} h

We substitute x with a and y with b:

x should be 3 units at the top, it has probably been cut off.

To work out b which should be the length at the bottom:

5+x+5 = 5+3+5 = 13

So b = 13

Now we substitute all values into the equation:

A = ((3+13)÷2)×7

A = (16÷2)×7

A = 8×7

A = 56

Therefore our answer is 56 square units

Answer:

<h2>Q4. S.A. = 752.28 m²</h2><h2>Q11. V = 384 ft³</h2>

Step-by-step explanation:

\bold{Q4}\\\text{We have}\\\text{two right triangles with legs a = 4m and b = 7m}\\\text{three rectangles}\ 7m\ \times 38m,\ 8.06m\ \times\ 38m\ \text{and}\ 4m\ \times\ 38m\\\\\text{The formula of an area of a right triangle:}\\\\A=\dfrac{ab}{2}\\\\\text{substitute:}\\\\A_1=\dfrac{(4)(7)}{2}=\dfrac{28}{2}=14\ m^2\\\\\text{The formula of an area of a rectangle}\ l\ \times w:\\\\A=lw\\\\\text{substitute:}\\\\A_2=(7)(38)=266\ m^2\\A_3=(8.06)(38)=306.28\ m^2\\A_4=(4)(38)=152\ m^2\\\\\text{The Surface Area:}

S.A.=2A_1+A_2+A_3+A_4\\\\S.A.=2(14)+266+306.28+152=752.28\ m^2

\bold{Q11}\\(look\ at\ the\ picture)\\\\\text{The formula of a volume of a pyramid:}\\\\V=\dfrac{1}{3}BH\\\\B-\text{area of a base}\\H-\text{height}\\\\\text{In the base we have the square. The formula of an area of a square with side a:}\\\\A=a^2\\\\\text{We have}\ a=12ft.\ \text{Substitute:}\\\\B=12^2=144\ ft^2\\\\\text{For}\ H\ \text{we need use the Pythagorean theorem:}\\\\H^2+6^2=10^2\\\\H^2+36=100\qquad\text{subtract 36 from both sides}\\\\H^2=64\to H=\sqrt{64}\\\\H=8\ m

\text{Substitute:}\\\\V=\dfrac{1}{3}(144)(8)=(48)(8)=384\ ft^3

Answer:

  A.  slope = -2; point = (8, -3)

Step-by-step explanation:

Compare to the point-slope form for slope m and point (h, k).

  y -k = m(x -h)

You see that k = -3, m = -2, h = 8, so ...

  • the slope is -2
  • the point is (h, k) = (8, -3)

Suppose "35" cars start at a car race. In how many ways can the top 3 cars finish the​ race?
Thepotemich [5.8K]

Answer:

The  value  is   \left 35  } \atop }} \right. P_3  =  39270

Step-by-step explanation:

From the question we are told that

    The  total number of cars is  n  =  35

     The  number cars considered is  r = 3

Generally the number of different top three finishes possible for this race of 35 cars  is mathematically represented as

       \left n } \atop }} \right. P_r  =   \frac{n!}{(n - r) !}

       \left 35  } \atop }} \right. P_3  =   \frac{35! }{(35 - 3) !}

       \left 35  } \atop }} \right. P_3  =   \frac{35 *  34 *  33 *  32! }{32 !}

       \left 35  } \atop }} \right. P_3  =  39270
