The vertices of a right- angled triangle are A(1,0), B(7.0) and C(1,6). Plot the points A, B and C on the cartesian plane below. Hence find the area of ABC

Answers

Answer 1

Answer:

[tex]A=21[/tex]

Step-by-step explanation:

From the question we are told that:

Co-ordinates

[tex]A(1,0), B(7.0)\ and\ C(1,6)[/tex]

Hence Plotting the Cartesian plane we have

Base [tex]b=7[/tex]

Height [tex]h=6[/tex]

Generally the equation for The Area of a Triangle  is mathematically given by

 [tex]A=\frac{1}{2}b*h[/tex]

 [tex]A=\frac{1}{2}*7*6[/tex]

 [tex]A=3.5*6[/tex]

 [tex]A=21[/tex]

In a certain Algebra 2 class of 30 students, 7 of them play basketball and 15 of them
play baseball. There are 10 students who play neither sport. What is the probability
that a student chosen randomly from the class plays basketball or baseball?

Answers

Answer:

P=2/3

Explanation:

since there are 10 students who play neither sport over 30, this means 20 students play basketball or baseball or both! (among them 2 students who play both basketball and baseball)

∴ the probability that a student chosen randomly from the class plays basketball or baseball is 20/30 and that equals 2/3 or 66.66%

Lee is buying roses. If each rose costs $2, which equation does not describe how many roses Lee might buy for $24?

Answers

Answer:

[tex](a)\ y = 2x[/tex]

[tex](b)\ x= 12[/tex]

Step-by-step explanation:

Given

[tex]rose = \$2[/tex]

Solving (a): The equation

Let

y = total amount

x = number of roses

So:

If [tex]x = 1, y = 2[/tex]

If x = x.

[tex]y = 2* x[/tex]

[tex]y = 2x[/tex]

Solving (a): Number of roses for $24

This implies that

[tex]y = 24[/tex]

So:

[tex]y = 2x[/tex]

[tex]24 = 2x[/tex]

Divide both sides by 2

[tex]12 = x[/tex]

[tex]x = 12[/tex]

You have a moving box with a volume of 16 ft3. You know that the box has a length of 2 ft and a height of 4 ft, but you don’t know the width. You need to know all three dimensions to make sure it can fit in the back of the truck. What is the width of the box?
3 ft
4 ft
2 ft
5 ft

Answers

Answer:

2ft

Step-by-step explanation:

The width of the box is 2 ft.

Here,

Volume of box = 16 ft^3

Length of box = 2 ft

Height of box = 4 ft

We have to find the width of box.

What is Volume of box?

The volume of box is defined as, the multiply of length, width, height.

Now,

Volume of box = 16 ft^3

Length of box = 2 ft

Height of box = 4 ft

Since, Volume of box = Length x width x height

Let width of box is x ft.

Volume of box = 2 * x * 4

16 = 8x

x = 2

Hence, The width of the box is 2 ft.

1. x times 1 divided by 4 is 3, a simpler way to put it!

x would be 12 since 12x1 is 12
