What is area?Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.
From the given figure,
Dimensions of a large rectangle, length is 12 ft and breadth is 9 ft.
Area of the large rectangle = Length×Breadth
= 12×9
= 108 square feet
Dimensions of a smaller rectangle, length is 12-7=5t ft and breadth is 13-9=4 ft.
Area of the smaller rectangle = Length×Breadth
= 5×4
= 20 square feet
Total area = 108+20
= 128 square feet
Therefore, the number of square feet of carpet Sara needs is 128 square feet.

Answer:
The area is 3.14 units squared.

8. Find the surface area of a triangular pyramid if the area of each phase is 16 cm² and each of its lateral faces has an area of 9 cm².
Answers
Answer:
The base of a right pyramid is an equilateral triangle with area 16√3 cm². area of one of its lateral faces is 30 cm²
To find : height (in cm) i
Solution:
The base of a right pyramid is an equilateral triangle with area 16√3 cm²
Area of an equilateral triangle = (√3 / 4) Side ²
(√3 / 4) Side ² = 16√3
=> Side ² = 64
=> Side = 8 cm
Distance of center of triangle to mid point of Side for Equilateral triangle = side/ 2√3 = 8/ 2√3 = 4/√3
Let say Height = H
Slant Height = √((4/√3)² + H²)
Area of lateral surface = (1/2) * base * Slat Height
= (1/2) * 8 * Slant height = 30
=> Slant height = 15/2
15/2 = √((4/√3)² + H²)
=> 225/4 = 16/3 + H²
=> 611/12 = H²
=> H = 7.135 cm

Since 7 is being added to the variable, subtract 7 to isolate the variable.
To keep the equation balanced, subtract 7 from both sides of the equation.

Answer:
I couldn't tell which angle you meant, so the two missing angles are Q = 56 and S = 68
Step-by-step explanation:
Q = 180 - 124
Q = 56
56 (angle Q) + 56 (angle R) = 112
S = 180 - 112

A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price of $315.
A-what is the original price?
B-How much money did you save off of the original price?
C-What percent of the original price is the sale price?
Answers
Answer:
Step-by-step explanation:
sale price = original price minus discount.
discount = original price * discount percent / 100.
let s represent the sale price.
let p represent the original price.
let d represent the discount.
let k represent the discount percent.
the above formulas become:
s = p - d
d = p * k/100
we know that s = 315.
we know that k = 30.
formulas become:
315 = p - d
d = p * 30/100
simplify these formulas to get:
315 = p - d
d = .3p
B. $315 - $409.5 = 94.5
C. 70%

Step-by-step explanation:
Answer:
A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled. Because of this, it is also called a direct variation. The equations of such relationships are always in the form y = mx , and when graphed produce a line that passes through the origin. In this equation, m is the slope of the line, and it is also called the unit rate, the rate of change, or the constant of proportionality of the function.

Step-by-step explanation:
c = a^2 + b^2 = 10^2 + 24^2 = 26
Answer:
26m.
Step-by-step explanation:
since the triangle has a 90° angle, it means that the triangle is a Right - angled triangle. So, we are going to use the pathagorean theorem to find the missing side.
a² + b² = c²
a and b are the two shorter and adjacent sides to the 90° angle
c is the hypotenuse
10² + 24² = c²
100 + 576 = c²
676 = c²
find the square root of 676 to get c = 26.

(#5) A carpenter has two different-sized circular saws. The smaller saw has the radius shown. I couldn't show it, so it is 1.25 inches. The larger saw has a diameter that is 1.5 inches greater than the diameter of the smaller one. How much greater is the circumference of the larger saw than the smaller saw? Use 3.14 for π. Attach a picture of your work. *
Answers
Answer:
4.71 in. difference
Step-by-step explanation:
so, the radius of the smaller saw is 1.25 and the diameter is double the radius. so it is 2.5 in diameter. the larger saw is 1.5 in greater which is 4 in.
to find circumference, you have to use the solution C = πd or circumference = pi x diameter.

Myron records the number of chirps per minute (x) that crickets make at different temperatures(Y ) in degree Fahrenheit. he determines that the association is linear and that the line of best fit is Y=1/6x+60.what is the interpretation of the slope and y intercept of this question?
Answers
Option (D), predicts the interpretation of the slope and y-intercept of this equation is the correct answer.
What is a linear equation?A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. A linear equation is represented graphically by the line whose points give the collection of solutions of the equation.
For the given situation,
The graph shows the Myrons record of number of chips per minute to temperature in degrees.
Let x be the number of chirps per minute.
Let y be the crickets make at different temperatures in degree Fahrenheit.
The linear equation of line that best fit is Y = 1/6x + 60.
The general form of equation is y = mx + c, where m is the slope and c is the y-intercept.
Here slope, [tex]m=\frac{1}{6}[/tex] and
y-intercept = [tex]60[/tex]
From the graph, the slope predicts a temperature increase of about (1/6)° for every increase of 1 chirp per minute. The y-intercept shows that when crickets are not chirping (x=0), the temperature is 50°.
Hence we can conclude that option (D), predicts the interpretation of the slope and y-intercept of this equation is the correct answer.
