Answer 1

Answer:

9cm and 2cm

Step-by-step explanation:

∴ They're similar triangles.

∴ [tex]\frac{a}{3}[/tex]= [tex]\frac{6}{b}[/tex] = [tex]\frac{3}{1}[/tex]

∴ a = 9cm

∴ b = 2cm

Dalvin answered 51 questions correctly on his multiple choice science final and earned a grade of 85%. How many total questions were on the final exam?

Answers

Answer:

Step-by-step explanation:

Divide the number of questions answered correctly by his percentage

51 / 85 = 0.6

Now multiply that answer by 100 to see how many questions are on the quiz

0.6 x 100 = 60

Check your work by dividing that number by the number he answered correctly

51 / 60 = 0.85

Which inequality statement describes the two numbers: - 22 and a number 47 units to the right of -22?
A)
-22 > 47
B)
-22 < 47
C)
-22 > 25
D)
-22 < 25

Answers

Answer:

D) -22 < 25

Step-by-step explanation:

If the number is 47 units to the right, then the number will be larger than -22, because negative values get larger the closer they are to zero.

47 units right from -22 is the same as: -22 + 47, which equals 25.

So, we can conclude that -22 < 25 is the inequality.

The rotation of the triangle ABC 360 degrees about the y-axis forms a cone

How to determine the shape after rotation?

From the question, we understand that the triangle ABC is a right triangle

The vertical cross-section of a cone is a right triangle.

This means that a right triangle can be rotated 360 degrees on one of its legs (opposite or adjacent) to form a cone

Hence, the rotation of the triangle ABC forms a cone

To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator. The LCM of the denominators of fraction or rational expressions is also called least common denominator, or LCD. Write each expression using the LCD.

Answer ↓The first step when adding or subtracting rational expressions with unlike denominators is to multiply the denominators together.

Explanation ↓

Adding or subtracting rational expressions is remarkably similar to adding and subtracting fractions, since a rational expression is a fraction.

The operations are the same.

When adding or subtracting fractions with unlike denominators, we multiply the denominator of one fraction times the denominator of the other fraction, and then alter the numerators.

The process with rational expressions is the same.

So the first step is to make sure both rational expressions have the same denominator.

What are rational numbers?

Rational number are numbers that include the square root of prime numbers

Given the following parameters

A= √3
B = 2√3C = √25 = 5
D = √16 = 4

We need to determine the operation that will result in a rational number

A + B = √3 + 2√3

A+B = 3√3

A+D = √3 + 4
B + D = 2√3 + 4

A + A = √3 +√3 = 2√3

Hence the expression that results in rational number are A+B, A+D, B+D and A+A

Purchasing the correctly sized BMX bike is based on the height of the rider. In order to fit a customer, the salesman can use the equation b=0.29h+1.35 where b is the size of the BMX bike frame in inches and h is the height of the rider in inches.

Answers

Answer:

(a) 1 inch of rider ⇒ 0.29 inches of frame

Step-by-step explanation:

The "slope" in the equation is the coefficient of the independent variable. Here, that variable is "h", and its coefficient is 0.29. That is, the height of the rider is multiplied by 0.29 (and a constant is added) in order to find the height of the frame.

The meaning of the value 0.29 is that a 1 inch increase in the rider's height should result in a 0.29 inch increase in the height of the frame of the bike.

The question asks for an explanation of the slope, not its function in the equation. That is why we have chosen the first answer.

Answer: inch of rider ⇒ 0.29 inches of frame

Answers

The correct statement states that the sales range for team 2 is greater than the sales range for team 1.

What is the range?

The range is defined as the difference between the maximum value to the minimum value.

Team 1

Worker's Age Sales

25 30,000

27 29,000

28 32,000

33 35,500

Team 2

Worker's Age Sales

25 35,000

28 37,000

29 38,000

31 65,000

Range Team 1 = 38000 - 30000 = 8000

Range Team 2 = 65000 - 29000 = 36000

Thus, The sales range for team 2 is greater than the sales range for team 1.

Find the volume of the sphere shown. Give each answer round to the nearest cubic unit. 15 CM

Answers

Answer:

Step-by-step explanation:

the volume (V) of a sphere is calculated as

V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius )

here the diameter = 15, then r = 15 ÷ 2 = 7.5 , then

V = [tex]\frac{4}{3}[/tex]π × 7.5³

= [tex]\frac{4}{3}[/tex]π × 421.875
