The figure below shows a shaded rectangular region inside a large rectangle:

A rectangle of length 10 units and width 5 units is shown. Inside this rectangle is a smaller rectangle of length 4 units and width 3 units placed symmetrically inside the larger rectangle. The smaller rectangle is shaded gray.

What is the probability that a point chosen inside the large rectangle is not in the shaded region?

76%
50%
24%
12%

Answers

The area of the smaller rectangle is 12, and the area of the bigger one is 50, so the probability that it is not chosen inside the shaded region is (50-12)/(50)=76%

Answer

76% its right i took the test!

The number x ≤ 10 for the inequality (-1/5)x + 3 ≤ 1.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Negative one-fifth of the number, increased

by 3, is at most 1.

Number = x

This can be written as,

(-1/5)x + 3 ≤ 1

Solve for x.

(-1/5)x + 3 ≤ 1

(-1/5)x ≤ 1 - 3

(-1/5)x ≤ -2

x ≤ -2 x (-5/1)

x ≤ 10

Thus,

The number is less than or equal to 10.

A 2-bedroom apartment that rents for $520 a month is $40 less than twice the cost of a 1-bedroom apartment. What is the monthly rent of a 1-bedroom apartment?​

Answers

Answer:monthly rent of a 1-bedroom apartment= $280

Step-by-step explanation:

Let the  cost of 1 bed room apartment = x

And the cost of two bedroom apartment= 2x-40

Since the cost of of two bedroom apartment = $520  

Then the cost of one bed room part will be expressed as

520= 2x- 40

520+40 = 2x

560= 2x

x= 560/ 2

x= 280

Therefore the  cost of 1 bed room apartment = x= $280

Write the equation of a line with an undefined slope that passes through the point (-6,3)

Answers

Answer:

x = -6

Step-by-step explanation:

A line with an undefined slope is vertical and is always represented by the equation x = a number. That number, whatever it may be, represents the x-value of all the points it intersects. Thus, take the x-value of the point (-6,3) and put it into the equation. So, the equation must be x = -6.
