Jamila has a bag that contains one tile for each letter of the alphabet what is the propibility that she will pull a vowel?

1 answer:

4 0

For the first one, since there are 5 vowels in the alphabet, you would divide 26 from 5 and then multiply by 100. This would get you 9.6% So the probability is 19.2%
Since the percentage doesn't change and 52 is 26*2, you would multiply the number of vowels in question 1 by 2, which is 5*2, or 10 vowels in the bag

Hope this helped!!! :D

cylindrical vase holds 8,038.4 cubic centimeters of water. The height of the vase is 40 centimeters. What is the length of the r

iragen [17]

The radius of the cylindrical vase is 8 centimeters, if the cylindrical vase holds 8,038.4 cubic centimeters of water and the height of the vase is 40 centimeters.

Step-by-step explanation:

The given is,

Volume of cylindrical vase = 8038.4 cubic centimeters

Height of the cylindrical vase = 40 centimeters

Step:1

Formula for volume of cylindrical vase,

$Volume, V=\pi r^{2} h$ ......................(1)

Where, r - Radius of cylindrical vase

h - Height of cylindrical vase

From the given,

V = 8038.4 cubic centimeters

h = 40 centimeters

Equation (1) becomes,

8038.4 $= \pi r^{2} 40$

$=(3.14)(40)r^{2}$ (∵ $\pi$ = 3.14 )

$8038.4 = 125.6 r^{2}$

$r^{2} = \frac{8038.4}{125.6}$

$r =\sqrt{64}$

r = 8 centimeters

Result:

The radius of the cylindrical vase is 8 centimeters, if the cylindrical vase holds 8,038.4 cubic centimeters of water and the height of the vase is 40 centimeters.

If a= (-1,-3) and b= (11,8), what is the length of AB?

Margarita [4]

Answer:

4.80 units (3 s.f.)

Step-by-step explanation:

$distance \: formula \\ = \sqrt{(x1 - x2)^{2}+ (y1 - y2)^{2} }$

Hence, length of AB

= √(11+1)^2 - (8+3)^2

= √ 12^2 -11^2

= √ 23

= 4.80 units (3 s.f.)

Answer:

Quality Plumbing charges more per hour.

In the graph, you can see that it would cost $150 for their work plus $100 per hour based on the slope of the line.

A Plus Plumbing charges $140 for their work plus $60 per hour.
