Answer:

[tex]Ratio = 2:3[/tex]

Step-by-step explanation:

Given

[tex]Cards = \{2,5,7,8,9,11\}[/tex]

Required

Ratio of odd numbers to total

First, list out the odd numbers

[tex]Odd = \{5,7,9,11\}[/tex]

The card has 4 odd numbers out of a total of 6.

So, the ratio is:

[tex]Ratio = Odd : Total[/tex]

[tex]Ratio = 4:6[/tex]

Divide by 2

[tex]Ratio = 2:3[/tex]

Hence, the ratio of odd to total is 2 to 3

Answer:

84

Step-by-step explanation:

Let the third term be x.

So, the numbers will be:

24, 36, x, 126

Since, all the four terms are in proportion.

Therefore,

[tex] \frac{24}{36} = \frac{x}{126} \\ \\ x = \frac{24 \times 126}{36} \\ \\ x = \frac{3,024}{36} \\ \\ x = 84[/tex]

Answer:

-20(y-3)/3

Step-by-step explanation:

The expression can be written simplified as 6x - 4y + 12.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

The expression is given as:

3(6/5x+4y+6)-2(9/5x+8y+3)​

To simplify the expression, we need to use the rules of algebra to combine like terms and perform the necessary operations in the correct order.

First, we can distribute the 3 and the -2 to the terms inside the parentheses:

3(6/5x+4y+6) - 2(9/5x+8y+3)

= 18/5x + 12y + 18 - 18/5x - 16y - 6

Next, we can combine like terms:

= 18/5x - 18/5x + 12y - 16y + 18 - 6

= 6/5x - 4y + 12

Finally, we can simplify the fraction by dividing the numerator and the denominator by their greatest common divisor, which is 1:

= (6/1) / (5/1)x - 4y + 12

= 6x - 4y + 12

Therefore, the simplified expression is 6x - 4y + 12.

Answer:

a) $53.34

b) 84,360.9 gallons

Step-by-step explanation:

let 'x' = cost of bill for 30,000 gallons

a) i set up a proportion as follows:

$1.33/748g = x/30,000

i cross-multiplied and got $53.34

b) i set up a proportion as follows:

let 'y' = how many gallons $150 can buy

$1.33/748g = 150/y

i cross-multiplied and got 84,360.9 gallons

Answer:

3/2

Step-by-step explanation:

1-2x+5=4x-3

1-2x-4x+5=-3

1-6x+5=-3

-6x+6=-3

-6x=-3-6

-6x=-9

6x=9

x=9/6

simplify

x=3/2

Answer:

x=1.5

Step-by-step explanation:

combining everything: -2x+6=4x-3

adding 2x to both sides, you get

6=6x-3

add 3 to both sides, you get 9=6x

divide, and then you get 1.5

Answer:

Amy traveled at 4.5 mph, while Jim traveled at 6 mph. Therefore, Jim traveled at a greater average speed.

Step-by-step explanation:

Given that Amy drove her hoverboard 3 miles in 40 minutes, while Jim hopped 2 miles in 20 minutes, to determine who traveled at a greater average speed, the following calculation must be performed:

(3/40) x 60 = Amy's speed

0.075 x 60 = Amy's speed

4.5 = Amy's speed

So Amy traveled 4.5 miles per hour.

(2/20) x 60 = Jim's speed

0.1 x 60 = Jim's velocity

6 = Jim's speed

Instead, Jim traveled 6 miles per hour.

Therefore, Jim was the one who traveled at a greater average speed.

Answer:

The mean is 8.4

Step-by-step explanation:

First you find the class centers.

3-6 = 4.5

7-10 = 8.5

11-14 = 12.5

15-18 = 16.5

The sum of all the scores = 4.5 * 7 + 8.5 * 10 + 12.5 * 6 + 16.5 + 2 = 210

The sum of the number of scores = 7 + 10 + 6 + 2 = 25

The mean = 210/25 = 42/5 = 8.4

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle. Your best bet when learning/visualizing word problems is to draw a picture, then learn how to visualize in your head over time.

Answer:

anywhere within 13.5 < cm < 14.5   ie) 13.7cm

Step-by-step explanation:

Pythagoras for all diagonals or right angle sides.

12^2 + 6.5^2 = c^2

sqrt 144 +  sq rt 42.25 = c^2

c^2 = sq rt 186.25 =  13.6473441  = 13.7cm

nearest 10th of a cm = 13.5<cm<14.5

Answer:

1 hour

Step-by-step explanation:

We are given that

Day       Hours

Sunday    0

Monday   1.5

Tuesday    2.5

Wednesday  2.5

Thursday       3

Friday            0

Saturday       n

Mean number of hours of  study per day=1.5

Mean=[tex]\frac{sum\;of\;data\;}{total\;number\;of\;data\;points}[/tex]

Total number of days=7

Using the formula

[tex]1.5=\frac{0+1.5+2.5+2.5+3+0+n}{7}[/tex]

[tex]1.5\times 7=9.5+n[/tex]

[tex]10.5-9.5=n[/tex]

[tex]n=1[/tex]

Hence,  number of hours you need to study on Saturday=n=1

Answer:

x = 1  and y = 1

Step-by-step explanation:

This is a system of equations. To solve it, you need to get one of your variables by itself first. (that means getting the x, or y by itself, just like how you solve equations when you only need to solve for one variable). I decided to solve the first equation, which is -x - 2y = -3 I'll solve it for the x, since there is no number being multiplied to it.

Answer:

c

Step-by-step explanation:

Since area is lw  3*3=9

That depends on what you mean by a "way" of having children. Some of the more obvious answers: One. Four boys and four girls, there's no other way of getting that many boys or that many girls. 40320. Usually each child has its own distinct DNA. The information in DNA can be converted into a number, and there are 8-factorial = 8! = 40320 orderings for eight numbers. 70. If each boy is considered to be the same until it is born and then named, so that the first four boys will always be named the same way and the same for the girls, then you can find the number of ways using binomial coefficients. The number of ways of arranging four equal boys and four equal girls into an order, is the same as the number of ways of choosing four numbers from 1 to 8 representing the position of the boys in that order. The number of ways of choosing a set of 4 numbers from 8 is called "8 choose 4" sometimes written 8C4 and is calculated as (8*7*6*5)/(4*3*2*1) (The numererator product in nCr stops when you have r numbers) (8*7*6*5)/(4*3*2*1) = 70

Answer:
