A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares. What is the area of the shaded rectangle?
Answer:
Area of Rectangle = 28 cm²
Step-by-step explanation:
Given - A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares.
To find - What is the area of the shaded rectangle?
Solution -
The graph of the rectangle is as follows :
From the diagram, e can see that
Length of Rectangle = 7 units (cm)
Breadth of Rectangle = 4 units (cm)
We know that,
Area of Rectangle = Length × Breadth
= 7 × 4
= 28 cm²
⇒Area of Rectangle = 28 cm²

Find the volume of each square pyramid given its slant height. Round to the nearest tenth. It looks like a normal pyramid with a slant height of 2.8 and a base of one of the triangles is 1.2.
Answer:
1.344 cubic units
Step-by-step explanation:
Given data
Base edge a= 1.2
Hieght= 2.8
The expression for the volume of a pyramid is
V= a^2h/3
substitute
V= 1.2^2* 2.8/3
V= 1.44*2.8/3
V= 4.032/3
V= 1.34cubic units
What is the range of the function shown in the graph below?
Answer:
y= -3/2X + 2
Step-by-step explanation:
we get the gradient by picking any two points from the graph( it a linear graph)
using the point:
(x,y)= (-2,5) , (4,-4)
using M= (y2-y1)/x2-x1)
we get our gradient to be -9/6 which is
-3/2
using the equation of a straight line graph which is
y-y1=m(x-x1) and the point (4,-4)
we get
y-(-4)=-3/2(x-4)
----> y+4= -3/2x + 6
make y subject of the formula to take the form
y=mx+c
we get :
y=-3/2x + 2
Use elimination/linear combination to solve the following.
please help
Answer:
Step-by-step explanation:
3x + 4y = 17
5x - 4y = 7
you can thus cancel out 4y
Hence
8x = 24
Hence x = 3
Substituting’
3(3) + 4y = 17
9 + 4y = 17
Hence 17 - 9/4
= y = 2

Answer:
32
Step-by-step explanation:
what is the rate of change for y=5.6x+7
Answer:
5.6
Step-by-step explanation:
The equation is put in y = mx + b
where m = slope ( rate of change ) and b = y intercept
5.6 = m and 7 = b
Hence the rate of change for y = 5.6x + 7 is 5.6

Find the volume
V=bh
* B is length times width
Answer:
448 yd^3
Step-by-step explanation:
V = Bh where B is l * w
V = l*w*h
V = 8* 14* 4
=448 yd^3
Answer:
The volume of this rectangular prism is equal to [tex]448yd^{3}[/tex].
Step-by-step explanation:
From the question, we know the formula for the volume of a rectangular prism is V = Bh (where B is length times width, and "h" is the height).
Now we replace B (because we know that B is length times width) and get...
V = lwh (where "l" is the length of the prism, and "w" is the width of the prism.
Now we just substitute the values and get...
[tex]V = lwh = (14)(4)(8) = 448yd^{3}[/tex]

Please help. Find the area of the figure below.
Answer:
81 un²
Step-by-step explanation:
9 · 7 = 63 un²
(b · h) ÷ 2
(5 · 4) ÷ 2 = 10 un²
(4 · 4) ÷ 2 = 8 un²
8 un² + 10 un² + 63 un²
81 un²
Answer:
81 un^2
Step-by-step explanation:
Find area of the rectangle. 9 x 7 = 63
Find area of the triangle. 9 x 4 = 36/2=18
63 + 18 = 81
Find the area of the given regular polygon

Answer:
96
Step-by-step explanation:
once you fill in the Blanks that are solvable, you will work your way into the answer. For example, the first column, the missing number has to be 155-76 or 79. Now you can find your answer. In the second row, “no Laptop”, you have 79 (solved above) plus 17. So your answer is 79+17 or 96.
g + 19 = 38
Explain how to get the answer pls!
In order to find out what g is equal too,u must subtract 19 from both sides of the equation to get
g +19-19=38-19
the nineteens cancel out getting
g=38 -19
g=19
