Coins are marked with the letters A-G. What is the probability of selecting a coin with a vowel on it?

Lemur [1.5K]

A B C D E F G.

Out of these, 2/7 letters are vowels.

2 / 7 ≈ 0.286
0.286 * 100 = 28.6%

Therefore the correct answer is A.

The equation of line CD is Y=3X -3. Write an equation of a line perpendicular to line CD in slope intercept form that contains p

OLga [1]

(I'm learning this right now!)

y = 3x - 3
If a line is perpendicular to another line, they have negative reciprocal slopes.
So you would use the slope -1/3.

Use y - y₁ = m(x - x₁) to get an equation in slope intercept form.
Plug the numbers in.

y - 1 = -1/3(x - 3)
y - 1 = -1/3x + 1
y = -1/3x + 2

An equation of a line perpendicular to line CD is y = -1/3x + 2.

Please help I don’t understand if you answer and explain you get extra points with brainiest

miskamm [114]

2t > 324
divide each side by 2
2t/2 > 324/2
t > 162

12y >= 1
divide each side by 12
12y/22 >= 1/12
y >= 1/12

x/9.5 < 11
multiple each side by 9.5
x/9.5 * 9.5 < 11 * 9.5
x < 105.5

19 Which figure(s) below can have a triangle as a two-dimensional cross

Andrew [12]

The figures that can have a triangle as a two-dimensional cross section are (4) I, III, and IV, only

<h3>How to determine the figures?</h3>

The cross-section of three-dimensional figures are as a result of slicing the figure along its axis.

When the cube is sliced with its plane, it gives a triangle face
When a cone is sliced vertically, it gives a triangle face
One of the faces of a square pyramid is a triangle; so it has a triangle face

Hence, the figures that can have a triangle as a two-dimensional cross section are (4) I, III, and IV, only

The cost of renting a landscaping tractor is a $100 base fee plus the hourly rate.

agasfer [191]

Answer:

a. f(h) = 100 + mh and g(h) = 100 + 2mh

b. The slope of g(h) is double of slope of f(h).

c. f(x) = 100 + mx.

Step-by-step explanation:

The cost of renting a landscaping tractor is a $100 base fee plus the hourly rate.

a. If the hourly rate is $m per hour, then the function f(h) represents the cost of renting the tractor for h hours, then

f(h) = 100 + mh .......... (1)

If the hourly rate is doubled i.e. 2m, then the function g(h) represents the cost of renting the tractor for h hours, then

g(h) = 100 + 2mh ........... (2)

b. If we graph the function f(h) then the slope of the equation will be m and the y-intercept will be 100.

If we graph the function g(h) then the slope of the equation will be 2m and the y-intercept will be 100.

Therefore, in the case of g(h), the slope will be double the slope of f(h).

c. If the tractor is rented for x hours, then the function f(h) will be

f(x) = 100 + mx. (Answer)
