To do multiplication is to take (usually) two sets on numbers and put them together to make them one.
For example: let’s say you want to multiply 5 and 3
This means you do 5➕5➕5
Your answer would be 15.
5✖️3= 15
Now let’s say you want to multiply a two digit number
10✖️12
This means you add 10 together 12 times.
10. First do 0✖️2 which is 0 so put it at the bottom. Then 1✖️2 which is 2
x 12. Then do 1✖️0 and 1✖️1
——————
20
➕11x. You put a place holder in this case (x) which equals 0
———————
120
Then you are left with your answer
Hope this helps! :3
Multiplication is like adding but with less work.
For example 9x9 is equal to
9+9+9+9+9+9+9+9+9.
Another example would be 15x3
which is equal to
15+15+15
Or
3+3+3+3+3+3+3+3+3+3+3+3+3+3+3z

Answer: 2.35 square miles.
Step-by-step explanation:
To solve this exercise you must apply the formula for calculte the area of a sector in a circle, which is shown below:
[tex]A=r^2\pi(\frac{C}{360})[/tex]
Where C is the central angle in degrees and r is the radius.
Therefore, knowing that:
[tex]C=30\°\\r=\frac{6mi}{2}=3mi[/tex]
When you substitute values, you obtain the following result:
[tex]A=(3mi)^2\pi(\frac{30\°}{360})[/tex]
[tex]A=2.35mi^2[/tex]
Answer:
Area of sector = 2.355 miles²
Step-by-step explanation:
Formula:
Area of circle = πr²
Where r is the radius
Area of sector = πr²(C/360)
Where C is the angle of sector
It is given that radius of circle is 6 miles
To find the are of circle
Here diameter = 6 miles,
radius r = diameter/2 = 3 miles
Area = πr² = 3.14 * 3² = 28.26 miles²
To find area of sector
Here r = 3 and C = 30°
Area of sector = πr²(C/360) = 28.26*(30/360)
= 2.355 miles²

3 A classroom is arranged with 8 seats in the front row, 10 seats in the mid
Answer:
Option F. [tex]200.96\ ft[/tex]
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=\pi D[/tex]
in this problem
[tex]D=64\ ft[/tex]
substitute
[tex]C=\pi (64)=64\pi\ ft[/tex] -----> exact value of the circumference
Find the approximate value of the circumference
assume
[tex]\pi=3.14[/tex]
[tex]64\pi\ ft=64(3.14)=200.96\ ft[/tex]
The correct answer is option F. The measurement is closest to the circumference of the base of the observatory is 200.96 ft.
To find the circumference of the base of the observatory, we use the formula for the circumference of a circle, which is [tex]\( C = \pi \times d \)[/tex], where [tex]\( C \)[/tex] is the circumference and [tex]\( d \)[/tex] is the diameter of the circle.
Given that the diameter of the floor of the observatory is 64 feet, we can plug this value into the formula:
[tex]\( C = \pi \times 64 \) feet[/tex]
Using the approximation [tex]\( \pi \approx 3.14159 \)[/tex], we calculate the circumference as follows:
[tex]\( C \approx 3.14159 \times 64 \)[/tex] feet,
[tex]\( C \approx 200.96 \)[/tex] feet.
The complete question is:
An observatory is shaped like a cylinder standing on one of its bases with a dome on top. The diameter of the floor of the observatory is 64 feet, as shown in the diagram.
Which measurement is closest to the circumference of the base of the observatory in feet?
F 200.96 ft

What is the length of the diagonal of the square shown below?
Answer:
sqrt(50)
Step-by-step explanation:
Since it is a right triangle, we can apply the Pythagorem Theorem.
a^2 + b^2 = c^2
25 + 25 = c^2
50 = c^2
c = sqrt(50)
The length of the diagonal of the square is 5 [tex]\sqrt{2[/tex]
The length of the diagonal of a square is equal to the square root of 2 times the length of a side. In this case, the side length is 5, so the diagonal of the square is 5√2
Let's break down the steps to find the square root of 50:
1. **Given**: We have a right triangle with side lengths:
[tex]- \(a = 25\)\\ - \(b = 25\)2. Apply the Pythagorean Theorem: \[a^2 + b^2 = c^2\] \[25^2 + 25^2 = c^2\] \[50 = c^2\]3. Solve for \(c\): \[c = \sqrt{50}\]4. Calculate the square root of 50: \[c \approx 7.07\][/tex]
Therefore, the length of the hypotenuse (\(c\)) in this right triangle is approximately 7.07 units

The width of a picnic table is 3 times its length. If the length is 5/6 yd long, what is the area of the picnic table in square feet?
Answer:
The area of the picnic table is [tex]18.75\ ft^{2}[/tex] or [tex]18\frac{3}{4}\ ft^{2}[/tex]
Step-by-step explanation:
we know that
[tex]1\ yd= 3\ ft[/tex]
Let
L-----> the length of the table
W----> the width of the table
the area of the table is
[tex]A=LW[/tex]
Convert yards to feet
[tex]L=\frac{5}{6}\ yd=\frac{5}{6}*3=\frac{5}{2}\ ft[/tex]
[tex]W=3L[/tex]
[tex]W=3(\frac{5}{2})=\frac{15}{2}\ ft[/tex]
substitute in the formula
[tex]A=\frac{5}{2}(\frac{15}{2})=\frac{75}{4}=18.75\ ft^{2}[/tex]
To calculate the area of the picnic table, convert the length to feet and multiply by the width, also in feet, to find the area in square feet.
Explanation:The student is asking about the area of a picnic table in square feet when the width is 3 times the length and the length is given as 5/6 yard. To find the area, first, calculate the width by multiplying the length of 5/6 yard by 3, which gives 5/2 yards (or 2.5 yards).
Since there are 3 feet in a yard, we convert the measurements to feet: 5/6 yard is equal to 5/6 * 3 feet, and the width is 2.5 * 3 feet. Next, multiply the length and width in feet to find the area.
It is important to note that converting measurements should retain unit consistency throughout the calculation.

Lillian collects stickers. Of her collection, 5/12 are animals stickers. Of remainder, 5/14 are flower stickers. What fraction of her stickers are not animal or flower?
well, this is simple subtraction as it is! 12-5= 7 so 7 for animal. 14-5= 9 so 9 for flower. 9+7= 16! so your final answer is, 16.
Answer:
The fraction of her stickers that are not animal or flower is [tex]\frac{9}{24}[/tex]
Step-by-step explanation:
Topic: Fractions
Let A represent the fraction of stickers that are animals
Let S represent the remaining stickers including the flower stickers
Given
A = [tex]\frac{5}{12}[/tex]
To get the fraction of stickers that are not animal or flower, the summation of the fraction must be equal to 1.
Mathematically, A + S = 1;
By Substitution, A + S = 1 becomes
[tex]\frac{5}{12} + S = 1[/tex] ------ Collect like terms
[tex]S = 1 - \frac{5}{12}[/tex]
[tex]S = \frac{12 - 5}{12}[/tex]
[tex]S = \frac{7}{12}[/tex]
Hence, the fraction of her stickers that are not animal is [tex]\frac{7}{12}[/tex]
From the question, we have that [tex]\frac{5}{14}[/tex] of the remainder are flower stickers.
Let F = Flower Stickers
F = [tex]\frac{5}{14}[/tex] * S
F = [tex]\frac{5}{14}[/tex] * [tex]\frac{7}{12}[/tex]
F = [tex]\frac{5}{2}[/tex] * [tex]\frac{1}{12}[/tex]
F = [tex]\frac{5}{24}[/tex]
To get the fraction of stickers that are not animal or flower, the summation of the fraction must be equal to 1.
Mathematically, A + F + R= 1;
R = 1 - A - F
Where R represent the fraction of stickers that are not animal or flower
[tex]R = 1 - \frac{5}{12} - \frac{5}{24}[/tex]
[tex]R = \frac{24 - 10 - 5}{24}[/tex]
[tex]R = \frac{9}{24}[/tex]
Hence, the fraction of her stickers that are not animal or flower is [tex]\frac{9}{24}[/tex]
Which container has the greatest surface area? (Use 3.14 for π .)
cone

square pyramid
rectangular prism
Answer:
It is the Rectangular Prism.
Step-by-step explanation:
Sry, I don't have enough time to write out an explanation. Hope the answer helped!
Answer:
the cylinder container has the greatest surface area.
Step-by-step explanation:
The volume of cone is calculated by [tex]v=\frac{1}{3}\times\pi\times r^{2}\times h[/tex]
The volume of cylinder is calculated by [tex]v=\pi\times r^{2}\times h[/tex]
The volume of square pyramid is calculated by [tex]v=\pi\times r^{2}\times h[/tex]
The volume of rectangular prism is calculated by [tex]v=\frac{1}{3}\times B\times h[/tex]
The radius of cone is [tex]\frac{6}{3}[/tex]=[tex]2in[/tex], and slant height is 10 in.
height is calculated as h² = l²- r²
h² = l²- r²
h² = 10²- 3²
h² = 100- 9
h² =91
h= 9.54
The volume of cone is [tex]=\frac{1}{3}\times 3.14\times 3^{2}\times 9.54[/tex]
[tex]=\frac{1}{3}\times 3.14\times 9\times 9.54[/tex]
v=89.8668
The volume of cylinder is [tex]=3.14\times 3^{2}\times 10[/tex]
[tex]=3.14\times9\times 10[/tex]
v=282.6
The volume of square pyramid
The height of pyramid is calculated as h² = l²- r²
h² = 10²- 3²
h² = 100- 9
h² =91
h= 9.54
[tex]v=3.14\times 3^{2}\times 9.54[/tex]
[tex]v=3.14\times 9\times 9.54[/tex]
[tex]v=269.60[/tex]
The volume of rectangular prism[tex]v=\frac{1}{3}\times 6\times 10[/tex]
[tex]v=20[/tex]
Hence, the cylinder container has the greatest surface area.
Solve the equation. −5 = c7
Answer:
[tex] c = - \frac { 5 } { 7 } [/tex]
Step-by-step explanation:
We are given the following equation and we are to solve it for [tex]c[/tex]:
[tex] - 5 = c7 [/tex]
Switching the sides of the equation we get:
[tex] c \times 7 = -5 [/tex]
Then dividing both sides of the equation by 7 to get:
[tex] \frac { c \times 7 } { 7 } = \frac { - 5 } { 7 } [/tex]
[tex] c = - \frac { 5 } { 7 } [/tex]
ectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation? (x, y) → (x + 5, y – 3) (x, y) → (x + 5, y + 3) (x, y) → (x – 3, y + 5) (x, y) → (x + 3, y + 5)
Answer: third option.
Step-by-step explanation:
By definition, translation is transformation in which you move the shape.
Then, you know that the rectangle on a coordinate plane is translated 5 units up and 3 units to the left.
Therefore, you must add 5 units to each y-coordinate and subtract 3 units to each x-coordinate.
So, keeping the above on mind, you can conclude that the rule that describe this translation is the shown below:
[tex](x,y)[/tex]→[tex](x-3,\ y+5)[/tex]
what is 4 is to 3 as x is to 20

3x = 80, and then x = 80/3.
To solve this proportion problem, set up the equation 4/3 = x/20. Cross multiply and solve for x to get x = 80/3.
Explanation:This is a proportion problem. We can set up the equation:
4/3 = x/20
To solve for x, we can cross multiply:
4 * 20 = 3 * x
80 = 3x
Divide both sides by 3 to solve for x:
x = 80/3

Ted earns a salary of $900 a month and a commission of 10% on all sales over $5,000. This month his sales were $36,000. What were his total earnings for the month?
Answer:
$4,000
Step-by-step explanation:
He makes a flat rate of $900, plus 10% on sales over $5,000
He sold $36,000, so he gets paid on $36,000 - $5,000 = $31,000 of those sales.
10% of $31,000 is
$31,000(0.10) = $3,100
He made $900 + $3,100 = $4,000

what is the solution for x^2+64=0
Answer:
If we consider real numbers, there is no solution.
If we take into account imaginary numbers, there are 2 solutions. [tex]x=8i, -8i[/tex]
Step-by-step explanation:
We can take 64 to the other side and then take the square root.
Thus, we have:
[tex]x^2+64=0\\x^2=-64\\x=\sqrt{-64}[/tex]
We CANNOT take the square root of a negative number, so there is no solution.
BUT, if we take into account Imaginary Numbers, we can solve:
[tex]x=\sqrt{-64} \\x=\sqrt{(-1)(64)} \\x=\sqrt{-1} \sqrt{64} \\x=8i[/tex]
Where [tex]\sqrt{-1} =i[/tex]
AND, we can take the positive and negative versions of 8i, since squaring would take it back to original.
So the answer would be 8i and -8i
Answer:

What is angle?An angle is the formed when two straight lines meet at one point, it is denoted by θ.
Given that,
Lines m and n are parallel,
Also, value of ∠2 = 40°, ∠3 = 68°
First determine the value of angle 5 First determine the value of angle 1,
Since, angle of a line = 180°
∠1 + ∠2 + ∠3 = 180°
∠1 + 40 + 68 = 180
∠1 + 108 = 180
∠1 = 72
Since, lines m and n are parallel,
∠1 = ∠5
∠5 = 72°
So, the value of angle 5 is 72°.
