15) -5b + 6 + 3b = 3b - 18

Answer:

10%

Step-by-step explanation:

[tex]5 \div 50 = 0.1[/tex]

[tex]0.1 \times 100 = 10[/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.

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%.

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%.

A flowchart proof is a visual representation of logical steps used to prove a mathematical statement or theorem.

It involves breaking down the proof into a series of connected statements and reasons, organized in a flowchart format.

Each statement is supported by a reason or justification, demonstrating the logical progression of the proof. Flowchart proofs provide a clear and structured way to present mathematical arguments, allowing for easy comprehension and verification of the proof's validity.

They help in identifying key steps, dependencies, and the overall structure of the proof, making it easier to follow and understand the reasoning behind mathematical statements.

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]

[tex]n = \frac{63}{5} or 12.6[/tex]

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
