A store employee counts 285 different lawn decorations. He wants to organize them and place the lawn decorations on 9 shelves. About how many lawn decorations will go on each shelf? A About 30 B About 40 C About 50 D About 90
Answer: C) About 30
Step-by-step explanation: 285/9= 31.6666666667 which rounded to the nearest ten is equal to 30
There should be about 30 decorations on each shelf.
What is division?The opposite of multiplication is division. Assuming that 3 gatherings of 4 make 12 in augmentation, 12 isolated into 3 equivalent gatherings give 4 in each gathering in division.
The primary objective of partitioning is to perceive the number of equivalent gatherings that are shaped or the number of are in each gathering while sharing decently.
Given total lawn decorations = 285
and to arrange in 9 shelves
each shelves will have
285/9 = 31.6667

Consider circle C with angle ACB measuring 3 pi/4 radians if minor arc AB measures 9 pi inches what is the length of the radius of circle C if necessary round your answer to the nearest inch
Answer:
r = 12 inches
Step-by-step explanation:
In this question, we are asked to calculate the length of the radius of the circle.
This is accessible from using the length of an arc.
Mathematically, the length of an arc can be calculated using the formula;
Theta/360 * 2 * pi * r
Where Theta is the angle subtended at the center and r is the radius of he circle.
According to the question, Theta is 3pi/4 radians or let’s just say 0.75pi . This to degrees will be 135 degrees ( pi = 180 degrees)
Thus we have;
9 pi = 135/360 * 2 * pi * r
divide through by pi
9 = 270r/360
360 * 9 = 270r
r = (360 * 9)/270
r = 12 inches

of a 5 in the Choose... place.
times the value
Answer:
The statement "500 divided by 50 is 10" is a true statement
Step-by-step explanation:
In mathematics, we have a term that we refer to as Place Value.
Place Value in mathematics can be defined as the value that a digit has based on its position or place in a number.
Examples of place value is:
Thousands represented by Th
Hundreds represented by H
Tens represented by T
Units represented by U
In the above question,
500 ÷ 50 gives us 10.
This is true because, 500 as a number, the Digit 5 has a place value of hundreds
50 as a number , the digit 5 has a place values of Tens.
10 as a number, the digit 1 has a place value of Tens.
In mathematics, the multiplication of 2 numbers in a place value of Tens always gives us a place value of hundreds.
For example, 10 × 50 = 500
Likewise, when we divide, a number with a place value of hundreds by a number with a place value of tens, we have a number with a place value of tens.
For example: 500 ÷ 50 = 10.
Therefore, the statement "500 divided by 50 is 10" is a true statement

The leaning Tower of Pisa was completed in 1372 and makes 86 degree angle with the ground. The tower is 50 meters tall, measured vertically from the ground to the highest point. If you were to climb to the top then accidentally drop your keys, where would you start looking for them?
How far from the base of the tower would they land?
I made having no luck in figuring this out.
Answer:
The distance where the keys would drop from the base is 3.5m
Step-by-step explanation:
Height of the tower = 50m
Angle it makes to the ground = 86°
To solve this question, you have to understand that the tower isn't vertically upright and the height of the tower is different from the distance from the top of the tower to the ground.
The tower makes an angle 86° to the ground and that makes it not vertically straight because a vertically straight building is at 90° to the ground.
See attached document for better illustration.
The distance from where the keys drop to the base of the tower can be calculated using SOHCAHTOA
We have to use cosθ = adjacent / hypothenus
θ = 86°
Adjacent = ? = x
Hypothenus = 50m
Cos θ = x / hyp
Cos 86 = x / 50
X = 50 × cos 86
X = 50 × 0.06976
X = 3.488 = 3.5m
The distance where the keys would drop from the base of the tower is approximately 3.5m

Louis wants to carpet the rectangular floor of his basement. The basement has an area o f605 square feet. The width of the basement is 1/5 its length. What is the length of Louis's basement?
Answer:
Length = 55 ft
Step-by-step explanation:
Given:
Area of rectangular floor= 605ft²
Length= x
Width= 1/5x
Formula for area of rectangular floor= Length × width
Put the given into the formula.
605 ft² = x × 1/5x
605 ft² = x²/5
multiplying both sides by 5
605 ft² × 5 = x²/5 × 5
x² = 605 ft² × 5
= 3025 ft²
x= √3025 ft²
x= 55 ft
Put x into the unknown above.
Length= x
Width= 1/5x
Length = 55 ft

a. Two local supermarkets sell watermelons grown at McDowell's
farm. But Biggy Market sells their watermelons for $3.99 each,
regardless of size, whereas Harmless Trail Market sells their
watermelons for $0.19 per pound. For what weight will a
watermelon at Harmless Trail cost the same as any watermelon at
Biggy? If the largest watermelon grown at McDowell's farm
weighs 18 pounds, at which place should you buy your
watermelons?
Answer:
For the watermelon at Harmless to cost the same as any watermelon at Biggy, the watermelon needs to be 21 pounds.
You should buy your watermelon at Harmless.
Step-by-step explanation:
1. So in order to figure out the number of pounds, you need to divide 3.99 by 0.19 which should give u 21 pounds.
2. So in order to figure out where u should buy the watermelon from, u have to do 18 pounds times $0.19 which should give u $3.42 at Harmless while at Biggy it would cost $3.99
Find the focus and the directrix of the parabola with the equation y = –1∕2 (x – 8)2 – 6.
A) Focus = (–8,–61∕2), directrix is y = –51∕2
B) Focus = (–8,–51∕2), directrix is y = –61∕2
C) Focus = (8,–61∕2), directrix is y = –51∕2
D) Focus = (8,–51∕2), directrix is y = –61∕2
Answer:
c
Step-by-step explanation:
The focus of the parabola is (–8,–51∕2), directrix is y = –61∕2 option (C) is correct.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
(x - h)² = 4a(y - k)
(h, k) is the vertex of the parabola:
a = √[(c-h)² + (d-k²]
(c, d) is the focus of the parabola:
We have an equation for the parabola:
The parabolic equation also in the form of quadratic equation.
Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
y = (-1∕2)(x – 8)² – 6
The vertex of the parabola is (h, k)
h = 8, k = -6
The focus of the parabola:
(c, d)
c = -6
d = -6 - 1/2 = -13/2 = -6 1/2
Directrix of the parabola:
y = -6 - (-1/2)
y = -6 + 1/2
y = -11/2 = -5 1/2
Thus, the focus of the parabola is (–8,–51∕2), directrix is y = –61∕2 option (C) is correct.
