It's a proportion.
2 is to x as 15 is to 9, or 2/x = 15/9.
Multiply the means and extremes
15x = 18
divide both sides by 15 to get x by itself.
x = 1.2

Suppose a car dealer receives a profit of $500 for each mid-sized car m sold and $750 for each sport-utility vehicle s sold. The

valkas [14]

Answer:

$\boxed{\text{Four}}$

Step-by-step explanation:

500m = profit on mid-sized cars

750s = profit on SUVs

500m + 750s = total profit

You have two conditions:

(1) 500m + 750s ≥ 3500

(2) m ≥ 2s

Let s = 2

Check condition (1)

500m + 750 × 2 ≥ 3500

500m + 1500 ≥ 3500

500m ≥ 2000

m ≥ 4

Check condition (2)

(2) m ≥ 2 × 2

m ≥ 4

$\text{The dealer must sell }\boxed{\textbf{four}}\text{ mid-sized vehicles per month}}$

Check:

500 × 4 + 750 × 2 ≥ 3500 4 ≥ 2 × 2

2000 + 1500 ≥ 3500 4 ≥ 4

3500 ≥ 3500

OK.

In the file below. (Sorry, question has pictures can't write it out.)

As what I can observe, the pathway can be formed with 2 right triangles. Thus, I'll get the area of the 2 right triangles and multiply its area by the paving cost per square meter.

Area of Right Triangle: ab / 2
a = 6 2/3 m ⇒ 20/3 m; b = 3m

Area of 1 triangle= (20/3 m * 3 m) ÷ 2 = 20 ÷ 2 = 10 m²

Area of 2 triangles = 10m² * 2 = 20 m²

Total cost = $40 * 20m² = $800

Find the distance to the nearest tenth,between S(6,5) and T(-3,-4)

Doss [256]

Answer:

<h3>The answer is 12.7 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

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

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

S(6,5) and T(-3,-4)

The distance between them is

$|ST| = \sqrt{ ({6 + 3})^{2} + ({5 + 4})^{2} } \\ = \sqrt{ {9}^{2} + {9}^{2} } \\ = \sqrt{81 + 81} \\ = \sqrt{162} \\ = 9 \sqrt{2} \: \: \\ = 12.7279...$

We have the final answer as

<h3>12.7 units to the nearest tenth</h3>

Hope this helps you

Two consecutive odd numbers total -20 find the smaller

Yakvenalex [24]

Answer:

-9

Step-by-step explanation:

use an equation to solve this

consecutive means in succession, one after the other

since they're odd, both numbers have to be odd

let x be the first number

x+x+2=-20

+2 because if you only +1, one of the numbers would be even

2x+2=-20

-2. -2

2x=-22

x=-11

the smaller would be -9 since we are adding x and x+2 together
