Answer:
V = 4800 cm^3
SA = 2000 cm^2
Step-by-step explanation:
V = l x w x h
V = 20 x 8 x 30
V = 4800 cm^3
20 x 8 x 2 = 320 cm^2
20 x 30 x 2 = 1200 cm^2
8 x 30 x 2 = 480 cm^2
320 + 1200 + 480 = 2000 cm^2

Write an equation of the line that passes through point P and is parallel to the line with the given equation: P(2,5) Y-1=4x
Given:
The equation of a line is:
[tex]y-1=4x[/tex]
A line parallel to the above line passes through the point P(2,5).
To find:
The equation of the parallel line.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
The given equation is:
[tex]y-1=4x[/tex]
It can be rewritten as
[tex]y=4x+1[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=4[/tex]
It means the slope of the given line is 4.
We know that the slopes of two perpendicular lines are equal. So, the slope of the required parallel line is also 4.
The parallel line passes through the point P(2,5) with slope 4, thus the equation of the parallel line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-5=4(x-2)[/tex]
[tex]y-5=4x-8[/tex]
[tex]y=4x-8+5[/tex]
[tex]y=4x-3[/tex]
Therefore, the equation of the required parallel line is [tex]y=4x-3[/tex].
Leon makes a rectangular logo for his skateboarding club. He cuts from fabric two copies of the trapizoid shown and joins them to form a rectangle. What is the area of the rectangular logo leon makes
Answer:
Area of the rectangular logo is 56cm²
Step-by-step explanation:
If we look at the picture the 2 trapezoids make a rectangle.
The length of the rectangle = 9+5= 14 cm and the breadth = 4 cm
Area of the rectangle = Length * breadth
A= 14*4= 56cm²
Area of the rectangular logo is 56cm²
Area of the trapezoid = 28 cm²
Area of the trapezoid = 1/2height( base1+ base2)
= 1/2 (4) ( 5+9)
= 2(14)= 28 cm²
Area of 2 trapezoids = 28 cm²+28 cm²= 56 cm²

If a wheel of a bicycle covers 440m in 200 rotation. find the area of a wheel.
Answer:
7/22
Step-by-step explanation:
Area = 400/200 × 400/200 ×1/4 × 7/22 = 7/22
Step-by-step explanation:
Total distance covered in 200 rotation = 440 m
Distance covered in 1 rotation
= 440 / 200
= 2.2 m
Distance covered in 1 rotation = Circumference of circle so
circumference = 2πr
2.2 = 2 * 22/7 * r
2.2 = 6.28 r
r = 2.2 / 6.28
r = 0.35 m
Now Area of the wheel
= πr²
= 22 /7 * 0.35 * 0.35
= 0.385 m²
Hope it will help :)❤

Answer:
about 236.715 ft²
Step-by-step explanation:
area of a circle = πr²
so π7.5² = 176.7145868
area of a rectangle is b × h
so 15 × 4 = 60
60 + 176.7145868 = 236.7145868 ft² ≈ 236.715 ft² (for the nearest thousandths)

A table cost $275. An LCD television set cost $325 more than the table.
Find the ratio of the cost of the LCD television set to the cost of the table.
Express the ratio in its simplest form.
Answer:
table cost=275
LCD television cost=325+275
= 600
[tex]ratio = \frac{600}{275} \\ = \frac{120}{55} \\ = \frac{24}{11} [/tex]

What is the volume of the cylinder below?
A. 98pi units3
B. 784pi units3
C. 112pi units3
D. 196pi units3
Answer:
D) 196π
Step-by-step explanation:
Volume of a cylinder formula:
V = πr²h
Given:
r = 7
h = 4
Work:
V = πr²h
V = π7²(4)
V = 49(4)π
V = 196π
If the sum of a number and six is doubled, the result is three less than the number. Find the number.
Answer:
n = -15
Step-by-step explanation:
Represent the number by n.
Then 2(n + 6) = n - 3
Performing the indicated multiplication, we get:
2n + 12 = n - 3
Combining like terms, we get n = -15
what is 22% of 45
what is 32.5% of 250
Answer:
22%*45=
(22:100)*45 =
(22*45):100 =
990:100 = 9.9
32.5%*250=
(32.5:100)*250 =
(32.5*250):100 =
8125:100 = 81.25
Answer:
1) 9.9
2) 81.25
Step-by-step explanation:
1)
22% = 0.22
45(0.22) = 9.9
2)
32.5% = 0.325
250(0.325) = 81.25

Josh drops his phone from a height of 50 feet. The situation is best modeled by h = -16t^2 +50, where h is the height in feet and t is the time in seconds. How long will it take for the phone to hit the ground? Round to the nearest tenth.
It will take approximately 1.8 seconds for the phone to hit the ground.
What is meant by an Equation?A mathematical statement which includes two sides, namely, left and right hand side consisting of numbers or variables, which are connected by an "equal to" sign is called an equation.
Given in the question that,
Equation representing the situation of the height of the phone in t seconds, is,
h = -16t² + 50
where h is the height in feet and t is the time in seconds.
The phone hits the ground means that the height is 0 there.
Substituting h = 0,
-16t² + 50 = 0
-16t² = -50
t² = 50 / 16
t² = 3.125
t = 1.767 ≈ 1.8 seconds
Hence the time taken is 1.8 seconds to the nearest tenth.

Given that the four points A(1,2), B(2, -5), C(7,0) and D(p,q) are the vertices of the rhombus ABCD
calculate
a) the value of p and of q
Step-by-step explanation:
Three coordinates of a Rhombus is given to us. And the fourth coordinate is D(p,q) . Weneedtofind the value of p and q . We know that the diagonals of Rhombus bisect each other at right angles . So lets find the midpoint.
• Midpoint of AC :-
[tex]\tt\to Midpoint_{(AC)}= \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\tt\to Midpoint_{(AC)}= \bigg( \dfrac{1+7}{2},\dfrac{2+0}{2}\bigg)\\\\\tt\to Midpoint_{(AC)}= \bigg(\dfrac{8}{2},\dfrac{2}{2}\bigg)\\\\\tt\to \boxed{\orange{\tt Midpoint_{(AC)}= (4,1)}}[/tex]

_______________________________
Now since these two coordinates must be equal, therefore ,
