Find the value of x.
Area of rectangle = 36
▅ х
x + 5

Answers

Answer 1

The value of x is 4, which is determined by the quadratic equation.

What is the area of the rectangle?

The area of a rectangle is defined as the product of the length and width.

The rectangle of a rectangle = L × W

Where W is the width of the rectangle  and L is the length of the rectangle

We have been given that area of the rectangle = 36

Area of rectangle = width of the rectangle × length of the rectangle

Here the width of the rectangle = x

And length of the rectangle = x + 5

The rectangle of a rectangle = x × (x + 5)

36 = x² + 5x

x² + 5x - 36 = 0

x² + 9x - 4x - 36 = 0

(x + 9)(x - 4) = 0

x = -9 and x = 4

Take the value of x = 4 and the negative value is neglected because the dimension can't be negative.

Therefore, the value of x is 4.

Answer:

RT = 23

Step-by-step explanation:

We will have a line that essentially goes like this:

R-----S-----T

The distance from R to S is 12 units.

The distance from S to T is 11 units.

We need to find the distance from R to T.

R is the starting point and T is the ending point.

To find the total distance, we can add both line lengths.

12 + 11 = 23 units

A triangle has a base of 10 inches and a height of 8 inches. What percent of the area of the triangle is within 4 inches of the base?

Answers

Answer:

40%

Step-by-step explanation:

Firstly

Area of triangle when base is 10 inches and height is 8 inches

= 1/2*b*h

= 1/2*10*8

=40square inch

Again when base =4 inches

= 1/2*4*8

= 16square inches

percent of the area of the triangle is within 4 inches of the base

= 16/40*100%

= 40%

A triangle has an 8-inch height and a 10-inch base. The percent of the area of the triangle is within 4 inches of the base exists 40%.

What is meant by the area of triangle?

Area of triangle = 1/2 (b h), where b is the base and h is the height, is the fundamental formula for calculating a triangle's area.

The type of the triangle and the known dimensions can affect other formulas that are used to calculate the area of a triangle.

Given: A triangle has an 8-inch height and a 10-inch base.

Let the equation be

Area of a triangle = (1/2) bh

substitute the values in the above equation, we get

= (1/2) × 8 × 10

= 40 square inches.

Once more with a 4 inch base

= 1/2 × 4 × 8

= 16 square inches.

Within 4 inches of the base, % of the triangle's surface area

= 16/40 × 100%

= 40%

Therefore, the percent of the area of the triangle is within 4 inches of the base exists 40%.

There are 15 questions, and John got an 84% on the quiz, how many questions did John get right and how many wrong?

Answers

Answer:

John got 13 questions right and 2 questions wrong.

Step-by-step explanation:

15 questions right equals 100%.

100 {divided by} 15 = % for each question right

Each question is worth (100 diveded by 15) 6.7%.

84% {diveded by} 6.7% = 12.5

100% - 84% = 16%

16% {divided by} 6.7% = 2.38

Because 12.5 has a higher dicimle value than 2.38 and when the amount he got right is added to the amount he got wrong it needs to equal 15, 12.5 becomes 13 and 2.38 becomes 2.

Answer:

[tex]\frac{n}{15} =\frac{84}{100}[/tex]

[tex]n = \frac{21}{25}*5[/tex]

[tex]n = \frac{21*15}{25}[/tex]

[tex]n = \frac{315}{25}[/tex]

b = 92 degrees (choice B)

c = 92 degrees (choice D)

d = 92 degrees (choice F)

================================================

Explanation:

Angles a and b are supplementary because they form a straight angle when combined. The two angles add to 180

a+b = 180

88+b = 180 ... plug in a = 88

b = 180-88 ... subtract 88 from both sides

b = 92

------------

Angles b and c are congruent because they are alternate interior angles. Alternate interior angles are congruent when dealing with parallel lines.

Since the diagonal entrance ramps are parallel, this means the corresponding angles c and d are congruent.

Since b = 92, this means c = 92 and d = 92 also.

Help me -2 (8 - e) = 2 - e​

Answers

Answer:

e = 6

Step-by-step explanation:

Step 1: Write equation

-2(8 - e) = 2 - e

Step 2: Solve for e

Distribute -2: -16 + 2e = 2 - eAdd e to both sides: -16 + 3e = 2Add 16 to both sides: 3e = 18Divide both sides by 3: e = 6

Step 3: Check

Plug in e to verify it's a solution.
