Nadia thinks of a number she finds the squre root and the divides it by 5 her answer is 20 what number is she thinking of
Answer:
10000
Step-by-step explanation:
Let the number = x
Square root of x divided by 5 equals 20
√x / 5 = 20
Using cross multiplication
√x = 20 * 5
√x = 100
Take the square of both sides
(√x)² = 100²
x = 10000
Therefore, the number is 10000

A. 9.2%
B 20.4%
C. 45.1%
D. 57.1%
HELPP ASAP
Answer: it should be 9.2%
Step-by-step explanation:
The percentage of people in the [tex]41 - 50[/tex] age group and favored the Do-It-Yourself books will be [tex]9.2\%[/tex] .
What is Percentage ?Percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, [tex]"\%"[/tex] .
Percentage [tex]=\frac{Obtained\ Number}{Total\ Number} *100[/tex]
We have,
Total number of people [tex]=750[/tex]
Number of people in the [tex]41 - 50[/tex] age group [tex]=268[/tex]
Number of people in the [tex]41 - 50[/tex] age group and favored the Do-It-Yourself books [tex]=69[/tex]
So,
Percentage of favored the Do-It-Yourself books in the [tex]41 - 50[/tex] age group [tex]=\frac{Do-It-yourself\ 41-50\ age}{Total\ Number\ people} *100[/tex]
[tex]=\frac{69}{750} *100[/tex]
[tex]=9.2\%[/tex]
So, the percentage of people is [tex]9.2\%[/tex] .
Hence, we can say that the percentage of people in the [tex]41 - 50[/tex] age group and favored the Do-It-Yourself books will be [tex]9.2\%[/tex] .

Using the Cosine Rule:
11^2 = 10^2 + 17^2 - 2*10*17cos A
cos A = (11^2 - 10^2 - 17^2) / (-2*10*17)
cos A = -268/-340 = 0.788235

Step-by-step explanation:
Answer:
1 = 30, 22. 2 = 45, 33.
Step-by-step explanation:

Answer: The sample portion would less closely model the population proportion
Answer:
Answer is that is will less closely model to the total population.
Step-by-step explanation:
This is because there are less numbers to be chosen and will be harder to find a proper medium and mean.

Eduardo has a wooden dowel rod that is StartFraction 8 Over 15 EndFraction of a yard long that he needs to cut into 24 equal-length pieces. What is the length of each piece of dowel rod?
StartFraction 1 Over 60 EndFraction of a yard
StartFraction 1 Over 45 EndFraction of a yard
StartFraction 5 Over 64 EndFraction of a yard
StartFraction 5 Over 8 EndFraction of a yard
Answer:
StartFraction 1 Over 45 EndFraction of a yard
Step-by-step explanation:
Length of the wooden dowel rod = 8/15 of a yard
Number of pieces = 24
What is the length of each piece of dowel rod?
Length of each piece of dowel rod = Total length of wooden dowel rod / number of pieces
= 8/15 ÷ 24
= 8/15 × 1/24
= (8*1) / (15*24)
= 8/360
= 1/45
Length of each piece of dowel rod = 1/45 of a yard

Cameron and some friends are going to the movies. At the theater, they sell a bag of popcorn for $5.50 and a drink for $3.75. How much would it cost if they bought 3 bags of popcorn and 6 drinks? How much would it cost if they bought pp bags of popcorn and dd drinks?
Answer:
Total cost= $39
Step-by-step explanation:
Giving the following information:
At the theater, they sell a bag of popcorn for $5.50 and a drink for $3.75.
First, we will establish the total cost formula:
Total cost= 5.5p + 3.75d
p= number of bags of popcorn
d= number of drinks
Now, for 3 bags and 6 drinks:
Total cost= 5.5*3 + 3.75*6
Total cost= $39

Answer:
The area of the triangle is 351cm^2.
Step-by-step explanation:
To find the area of a triangle, the formula is (1/2) x base x height. In this case, the height would be a line that cuts straight through the center of the triangle. However, this height is not given to us. We can still find it through Pythagoras' Theorem though.
Let A be the tip of the triangle, and B and C be the points on either side of the triangle. Assuming an imaginary line that cuts the triangle in a symmetrical half, let T be the point at the end of the line, directly below point A.
Using Pythagoras' Theorem,
AB^2 = AT^2 + TB^2
AT^2 = AB^2 - TB^2
AT^2 = 30^2 - (26/2)^2
AT^2 = 30^2 - 13^2
AT =
[tex] \sqrt{ {30}^{2} - {13}^{2} } [/tex]
AT = 27.0370116692
So the length of AT is our height. We can now find the area of the triangle.
Area of triangle = (1/2) x 26cm x AT
Area of triangle = 351.4811516996
Area of triangle = 351cm^2 (To 3s.f.)

Jason just got tired for a new job and will make $80,000 in his first year. Jason was
told that he can expect to get raises of $5,000 every year going forward. How much
money in salary would Jason make in his 23rd year working at this job?
Answer:
$110,080
Step-by-step explanation:
This is an arithmetic sequence because each new term is obtained by adding $5000 to the preivous term.
The general formula for such an arithmetic series is
a(n) = $80,000 + ($5,000)(n - 1)
and so in his 23rd year Jason would make
a(23) = $80,000 + ($5,000)(23 - 1), or
$110,080
Answer:
$110,080 is the answer

Find the perimeter of the figure. Round all figures to the nearest hundredths place.
Isosceles trapezoid
A 70.24 ft
B 74.48 ft
C 79.42 ft
D 92.84 ft
Answer:92.84
Step-by-step explanation: 39+27+13.5+13.5 because the two sides are longer than 12
The perimeter of the trapezium is 143.94 ft.
We have,
The perimeter of an isosceles trapezium can be found by adding the lengths of all four sides.
In this case, the trapezium has height = 12 ft and parallel sides of length 27 ft and 39 ft.
To find the length of the non-parallel sides we can use the Pythagorean theorem:
a² = (39 - 27/2)² + 12²
a² = 1440
a ≈ 37.95 ft
Therefore,
The perimeter of the trapezium is:
P = 27 + 39 + 2a
P ≈ 27 + 39 + 2(37.95)
P ≈ 143.9 ft
Rounding to the nearest hundredth place,
we get P ≈ 143.94 ft.
Thus,
The perimeter of the trapezium is 143.94 ft.
