Answer:
17
Step-by-step explanation:
let the two numbers be X and Y
let larger number = Y
from the first statement
Y - X = 9 equation (1)
from the second statement
Y = 1+ 2X equation (2)
substitute equation (2) into (1)
1+2X-X = 9
1+X= 9
X = 9-1 = 8
X= 8
put X = 8 into equation (2)
Y= 1+2X
Y= 1+2(8)
Y= 1+16 = 17
larger number = 17.

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

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?
Answer:
60
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
Write the expression in exponential form.
Answer:
In exponential form given function is equal to [tex]N = b^{r}[/tex]
Step-by-step explanation:
We are given with function,
[tex]log_{b} ^[/tex] [tex]^{N} = r[/tex]
We have to express it in exponential form.
Consider,
[tex]log_{b}^[/tex] [tex]^ {N} = r[/tex]
exponential both side to the power of b as base of given log function is b.
we get
[tex]b ^{logb}[/tex] [tex]^ {N} = b^{r}[/tex]
[tex]N = b^{r}[/tex]
Therefore In exponential form given function is equal to [tex]N = b^ {r}[/tex]

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
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.

Darnell collected data from two different sales teams in his department, each with four employees the results of the study, based on each workers age and sales, are listed in the tables below. Which of the following is a true statement
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.

What are rational numbers?Rational number are numbers that include the square root of prime numbers
Given the following parameters
A= √3We 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

Find the perimeter and area of the parallelogram. 14 cm 18 cm 6 cm
Answer:
b
Step-by-step explanation:
The first step when adding or subtracting rational expression with unlike denominator is to
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.
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.

Find the volume of the sphere shown. Give each answer round to the nearest cubic unit. 15 CM
Answer:
a
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
= [tex]\frac{4\pi (421.875)}{3}[/tex]
≈ 1767 cm³ ( to the nearest cubic cm )
