Answer:
317.92 square inches
Step-by-step explanation:
Rectangle A:
Area of a rectangle = length × width
Length = 16 inches
Width = 13 1/4 inches = 53/4 inches
Area of a rectangle = length × width
= 16 inches × 53/4 inches
= (16 * 53) / 4 inches²
= 848/4
= 212 square inches
Rectangle B:
Area of a rectangle = length × width
Length = 10 1/3 inches = 31/3 inches
Width = 10 1/4 inches = 41/4 inches
Area of a rectangle = length × Width
= 31/3 inches × 41/4 inches
= (31 * 41) / (3 * 4) square inches
= 1271 / 12
= 105.92 square inches
How many total square inches of construction paper does Ginny need?
total square inches needed = Area of rectangle A + Area of rectangle B
= 212 square inches + 105.92 square inches
= 317.92 square inches

soccer ball inflation:
How many pumps will it take to fill the large soccer ball with a circumference of 71 inches? Recall that the amount of air in one pump was about 11 cubic inches.
must show all work and justify work
Answer:
549 pumps
Step-by-step explanation:
We'll begin by calculating the radius of the larger ball. This can be obtained as follow:
Circumference (C) = 71
Pi (π) = 3.14
Radius (r) =?
C = 2πr
71 = 2 × 3.14 × r
71 = 6.28 × r
Divide both side by 6.28
r = 71 / 6.28
r = 11.3 in
Next, we shall determine the volume of the larger ball.
Since a ball is spherical in shape, we shall use the formula for calculating the volume of a sphere to obtain the volume of the ball. This can be obtained as follow:
Pi (π) = 3.14
Radius (r) = 11.3 in
Volume (V) =?
V = 4/3πr³
V = 4/3 × 3.14 × 11.3³
V = 4/3 × 3.14 × 1442.897
V = 6041 in³
Finally, we shall determine the number of pumps will it take to fill the large soccer ball. This can be obtained as follow:
11 in³ = 1 pump
Therefore,
6041 in³ = 6041 in³ × 1 pump / 11 in³
6041 in³ = 549 pumps
Thus, it will take approximately 549 pumps of air to fill the large soccer ball.

Answer:
150 ft^2
Step-by-step explanation:
13 × 10 = 130 ft

What Is Sin of Sin Inverse of x?The inverse sine function (also called arcsine) is the inverse of sine function. Since sine of an angle (sine function) is equal to ratio of opposite side and hypotenuse, thus sine inverse of same ratio will give the measure of the angle.
sin ([tex]sin^{-1}x[/tex]) = x, whenever x ∈ [-1, 1] and
sin ([tex]sin^{-1}x[/tex]) is NOT defined whenever x ∉ [-1, 1].

What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
x2
12x + 32 = 4
Given:
The equation is:
[tex]x^2-12x+32=4[/tex]
To find:
The result of completing the square for the given equation.
Solution:
We have,
[tex]x^2-12x+32=4[/tex]
It can be written as:
[tex]x^2-12x=4-32[/tex]
[tex]x^2-12x=-28[/tex]
Now, we need to add half of square of coefficient of x, to complete the square.
Adding [tex](\dfrac{-12}{2})^2[/tex] on both sides, we get
[tex]x^2-12x+(\dfrac{-12}{2})^2=-28+(\dfrac{-12}{2})^2[/tex]
[tex]x^2-2(x)(6)+(-6)^2=-28+(-6)^2[/tex]
[tex]x^2-2(x)(6)+(6)^2=-28+36[/tex] [tex][\because (-a)^2=(a)^2][/tex]
Using the formula [tex](a-b)^2=a^2-2ab+b^2[/tex], we get
[tex](x-6)^2=8[/tex]
Therefore, the required equation after completing the square is [tex](x-6)^2=8[/tex].

Answer:
c is the answer
Step-by-step explanation:
because the triangle which isnot 180degee it isnot a triangle
The correct option is If the angle sum is not 180 degrees, then the figure is not a triangle.
What is a triangle?A triangle is a polygon with three edges and three vertices.
Given is a statement, If a figure is a triangle, then its angle sum equals 180°
The equivalent statement means that, it gives the similar meaning as the original statement.
So, in the options, the third one is :- If the angle sum is not 180 degrees, then the figure is not a triangle, is giving the same sense as the original statement If a figure is a triangle, then its angle sum equals 180°
Hence, we can say that 3rd is the correct option.
