The length of a rectangle is twice its width.
If the perimeter of the rectangle is 54 yd, find its length and width.
Answer:
Length 18 yds, Width 9 yds
Step-by-step explanation:
2x + 2x + x + x = 54
Combine like terms
6x = 54
Divide both sides by 6
x = 9
Plug 9 into equation above
2(9) + 2(9) + 9 + 9 =
18 + 18 + 18 = 54

Question 9 of 10
If f(x) = 2x^2+ 1 and g(x) =x^2 - 7, find (f – g)(x).
O A. 3x2 + 8
B. 3x2 - 6
C. x2 - 6
D. x2 + 8
Answer:
x2 + 8
Step-by-step explanation:
The value of the composite function (f - g)(x) is x² + 8.
The correct option is D.
What is a composite function?Any function that is created by combining two or more other functions is referred to as a composite function. To put it another way, given two functions, f, and g, the composite function of f and g, denoted as f(g(x)), is a new function that applies g to the input x before applying f to the output of g (x).
Given:
f(x) = 2x² + 1 and g(x) = x² - 7.
To find (f – g)(x), we need to subtract g(x) from f(x):
(f - g)(x) = f(x) - g(x)
where f(x) = 2x² + 1 and g(x) = x² - 7.
Substituting these expressions into the equation, we get:
(f - g)(x) = (2x² + 1) - (x² - 7)
Simplifying the expression on the right-hand side by distributing the negative sign, we get:
(f - g)(x) = 2x² + 1 - x² - 7)
Combining like terms, we get:
(f - g)(x) = x² + 8.
Therefore, (f - g)(x) = x² + 8.

number of girls and boys in each group. What is the greatest number of groups can be
formed. How many girls and how many boys will be in each group?
Answer:
6 groups
2 girls, 3 boys
Step-by-step explanation:
To find the answer, first find the Greatest Common Factor or the GCF. The GCF in this case is 6. So, the amount of groups is 6. Then divide each number by 6, so there will be 2 girls in each group and 3 boys in each group.

The value of the arithmetic series is 550. The correct answer is C) 550.
To evaluate the arithmetic series, we can use the formula:
Sn = (n/2)(2a1 + (n-1)d)
Given:
a1 = 10 (first term)
d = 8 (common difference)
n = 11 (number of terms)
Plugging the values into the formula:
Sn = (11/2)(2(10) + (11-1)(8))
= (11/2)(20 + 10(8))
= (11/2)(20 + 80)
= (11/2)(100)
= 550
Therefore, the value of the arithmetic series is 550.
The correct answer is C) 550.

The perimeter of an equilateral triangle is 3 (+ 5). The perimeter of a rectangle is 2 (2x - 3) + 2(2). If the perimeters of the two figures are equal, then what is the value of r?
Answer:
3.25
Step-by-step explanation:
Perimeter of triangle = 3(5) = 15 cm
Perimeter of rectangle = 2(2x - 3 + 4)
Perimeter = 2(2x + 1)
Perimeter = 4x + 2
4x + 2 = 15
4x = 15 - 2
4x = 13
x = 13/4

Plot the minuend and the difference on the number line.
The difference between the numbers 1.4 and 1.7 is -0.3 after using the number line.
What is a number line?It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.
It is given that:
As we can see in the number line:
1.4 < 1.7
If we take the difference between these two numbers
From the number line:
= 1.4 - 1.7
= -0.3
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
After using the arithmetic operation concept:
The difference between the numbers:
= 1.4 - 1.7

*16. Camping Norman's camping tent has a volume of 72.576 cubic inches. What is the
volume of the tent in cubic feet?
1 square meter is equivalent to 0.0001 square centimeter
72.576 cubic inches. in cubic feet is 0.042 cubic feet
Conversion in math is a way of changing the value of an expression using units.
1) In order to change 1 square meter to square centimeters, we will use the conversion
1m = 0.01cm
Taking the square of both sides
(1m)² = (0.01cm)²
1m² = 0.01cm * 0.01cm
1m² = 0.0001cm²
This shows that 1 square meter is equivalent to 0.0001 square centimeter
2) We are to convert 72.576 cubic inches to cubic feet. Using the conversion factor:
1 cubic inch = 0.000578704 cubic feet
72.576 cubic inches = x
Cross multiply
x = 72.576 * 0.000578704
x = 0.042 cubic feet

How long of a ladder is needed to reach a window sill 50 feet above the ground if the ladder rests against the building making an angle of 75∘ with the ground? Round your answer to the nearest foot and do not include units.
The length of the ladder needed to reach a window with 50 feet above the ground is 52 ft.
How to find the length of the ladder to reach the window?The angle formed with the ground and the ladder is 75 degrees.
The window is 50 ft above the ground.
The situation forms a right triangle.
Therefore, using trigonometric,
sin 75 = opposite / hypotenuse
where
hypotenuse side = length of the ladderopposite side is height of the window from the ground where the ladder head will be placed.Therefore,
sin 75 = 50 / h
cross multiply
h = 50 / sin 75
h = 50 / 0.96592582628
h = 51.763809036
h = 52 ft
Therefore, the length of the ladder needed to reach a window with 50 feet above the ground is 52 ft.
