Answer 1

Answer:

Answer:

A) 83 km/ hour

B) 2/7 penalties / game

C) $16 / CD

D) 9 donuts / box

Step-by-step explanation:

For this question they are asking for the distance traveled in 1 hour.

Since 747km was travelled in 9 hours, we divide 747 by 9 to find the distance travelled in 1 hour

747 ÷ 9 = 83

The unit rate is 83 km/ hour

You have to find the number of penalties per game

Like before divide 10 by 35:

10 ÷ 35 = 10/35 = 2/7

2/7 penalties / game

Find the cost of 1 CD :

64 / 4 = 16

$16 / CD

Find the amount of donuts per box:

72/8 = 9

9 donuts per box

The formula for the lateral area of a right cone la=pirs, where r is the radius of the base and s is the slant height of the cone. which are equivalent equations?

Answers

Answer:

$\pi r √(r^2+h^2)$

Step-by-step explanation:

Given that there is a cone with radius r and slant height s.

We know that lateral surface area of the cone is

= $\pi r s$

Alternately if instead of s, h is known we can write this in terms of h also.

Consider the right triangle formed by slant height, height and radius of the cone.

Using Pythagorean theorem we have

$s^2=r^2+h^2$

Or $s=√(r^2+h^2)$

Hence lateral surface area of the cone

= $\pi r √(r^2+h^2)$

Whats the mean, media, maximum,minimum,mode and range of 1,2,1,3,4

Answers

First put the numbers in order least to greatest.
(1,1,2,3,4)
The mean is the average of the group of numbers.
Too find it you add all the numbers up and divide it by how many numbers there are.
In this case it would be 11 divided by 5 so the mean would be $2 (1)/(5)$

Median is just another word for middle. After putting the numbers in order, the number in the center of the group is the median, in this case it would be 2.

The maximum would just be the largest number which is self explantory (4)

The minimum would be the lowest number (1)

I was taught to see mode as the word "most". All you do is see which number occurs the most. If all the numbers only occur once, your answer would be "No mode"

It is that simple! The Range is the difference between the lowest and highest number. So all you have to do is subtract the maximum by the minimum. In this case it would be 4-1 = 3

Solve for y: R (6x-11)° (9y-19)° (4x+23)°

Answers

Answer:

y = 12

Step-by-step explanation:

We first need to solve for x

(6x - 11)° and (4x + 23)° are vertically opposite angles and are congruent, so

6x - 11 = 4x + 23 ( subtract 4x from both sides )

6x - 4x - 11 = 4x - 4x + 23 ( simplify both sides )

2x - 11 = 23 ( add 11 to both sides )

2x - 11 + 11 = 23 + 11 ( simplify both sides )

2x = 34 ( divide both sides by 2 )

$(2)/(2)$ x = $(34)/(2)$ , that is

x = 17

Then

4x + 23 = 4(17) + 23 = 68 + 23 = 91

(9y - 19)° and 91 are a linear pair and sum to 180°

sum the 2 angles and equate to 180

9y - 19 + 91 = 180 ( simplify left side )

9y + 72 = 180 ( subtract 72 from both sides )

9y + 72 - 72 = 180 - 72 ( simplify both sides )

9y = 108 ( divide both sides by 9 )

$(9)/(9)$ y = $(108)/(9)$ , that is

y = 12
