The given statement is "nine times five less than twice x".

So, twice of x can be written as 2x and nine times five is 9*5.

Now 9*5 less 2x means we need to take out 9*5 from 2x.

Hence, this statement will be converted into an algebraic expression as follows:

2x-9*5

Leanne runs a lap in 12 minutes. Kory runs a lap in 9 minutes. If they

klemol [59]

Kory and Leanne will meet each other again after 36 minutes from starting i.e. at 10:36 am .

<u>Step-by-step explanation:</u>

Here we have , Leanne runs a lap in 12 minutes. Kory runs a lap in 9 minutes. We need to find out that If they both start running at 10 am, at what time will they both cross the start together again . Let's find out:

Kory runs a lap in 9 minutes and , Leanne in 12 minutes , in order to find at what time will they both cross the start together again we will find LCM of 9 & 12 :

⇒ $\frac{9(4)}{12(4)}$

⇒ $\frac{36}{36}$

So ,LCM of 9 & 12 is 36 .That means Kory and Leanne will meet each other again after 36 minutes from starting i.e. at 10:36 am .

In clear way , Kory will run race as :

1st lap = 9 minutes

2nd lap = 18 minutes

3rd lap = 27 minutes

4th lap = 36 minutes , i.e. at 10:36 am he'll complete his 4th lap

For , Leanne

1st lap = 12 minutes

2nd lap = 24 minutes

3rd lap = 36 minutes i.e. at 10:36 am he'll complete his 3rd lap .

This means Kory & Leanne will meet at 10:36 am completing there 4th and 3rd lap respectively .

A garden supply store sells two types of lawn mowers.Total sales of mowers for the year were $8379.79. The total number of mower

Sliva [168]

Value + value = 8379.70
249.99x + 329.99*30-329.99x = 8379.70
-80x + 9899.70 = 8379.70
-80x = -1520.00
x = 19 (number of the cheaper mowers sold)
30-x = 11 (number of more expensive mowers sold)

Laurissa rolls two number cubes, each with the numbers 1 though 6. Laurissa adds the numbers that appear on the roll. Which two

DanielleElmas [232]

Answer:

I will use the notation:

Cube1 + Cube2 = sum.

Ok, each number cube has 6 options, so the total number of possible combinations is equal to the product of the number of options for each event we have two events (two number cubes).

Then:

C = 6*6 = 36

we have 36 possible combinations.

Now, let's look at the sums that have the same number of combinations (which would mean that have the same number of combinations).

For example, the lower result possible is two ones:

1 + 1 = 2

(only one outcome adds up to 2)

And the maximum result possible is two sixes:

6 + 6 = 12

(only one outcome adds up to 12)

Then 2 and 12 have the same probability, 1/36.

Now we can keep loking at 2 + 1 and 12 - 1.

2 + 1 = 3

The outcomes that add up to 3 are:

1 + 2 = 3

2 + 1 = 3

(two outcomes out of 36)

12 - 1 = 11

The outcomes that add up to 11 are:

6 + 5 = 11

5 + 6 = 11

(Two outcomes out of 36)

Then 3 and 11 have the same probability, 2/36.

And we can notice the pattern here.

4 and 10 will have the same probability 3/36

5 and 9 will have the same probability 4/36

6 and 8 will have the same probability 5/36

7 is the only option that does not have a pair, the probability is 6/36.

A rectangle with the bottom labeled 2.7 times 10 cubed feet and the right side labeled 3.5 times 10 cubed feet

disa [49]

The area of the portion of the rectangular field that has crops growing is 4.7 x 10² ft².

<h3>Area of the rectangle</h3>

The area of the rectangle is calculated as follows;

Area of rectangle = L x b

where;

L is length of the rectangle
b is the breadth of the rectangle

Given parameters;

Length of the rectangle = 3.5 x 10 ft = 35 ft
Breadth of the rectangle = 2.7 x 10 ft = 27 ft

Area = 35 ft x 27 ft

Area = 945 ft²

<h3>Area of the portion of the field that has crops growing</h3>

Area = ¹/₂ x 945 ft²

Area = 472.5 ft²

Area = 4.7 x 10² ft² (2 significant digits)

The two significant digits was chosen based on the number of significant digits of the rectangle dimensions (that is, the length and breadth are given in 2 significant digits, so the area has to be in 2 significant digits to maintain consistency).
