Suzanna wants to measure a board, but she doesn't have a ruler to measure it. However, she does have several copies of a book she knows is 17 centimeters tall.

A: Suzanna lays the books end to end and finds that the board is the same length as 21 books. How many centimeters long is the board?

B: Suzanna needs a board that is at least 3.5 meters long. Is the board long enough? Explain.

Answer:

$11

Step-by-step explanation:

Let's take 20% and convert it into a decimal, which is .20. Multiply that percentage by $55 (.20 * 55) and you get $11, which is the answer.

Answer: 15 pumps

More the number of pumps lesser is the time taken to fill the tank

Number of pumps ∝ 1/Time

n = k / t

[where k = constant]

In 1st case

5 = k / (1.5)

k = 7.5

In second case

n = k / t

= 7.5 / 0.5

= 15

∴ 15 pumps are used to fill the empty tank in half an hour.

Answer:

Exponential growth, 130%

Step-by-step explanation:

The number being multiplied as x is changing is 1.3, and that represents growth because it is greater than 1. The rate of growth would then be 130%, as 1.3 represented as a percentage is 130%.

Based on information given on rhombus' dimensions and the area formula of the rhombus, we conclude that the area of the figure is 54 square inches.

The area of a rhombus (A), in square inches, is represented by a model in terms of the diagonals of the figure, which is described below:

A = 0.5 · d · D     (1)

Where:

If we know that d = 9 in and D = 12 in, then the area of the rhombus is:

A = 0.5 · (9) · (12)

A = 54 in²

Based on information given on rhombus' dimensions and the area formula of the rhombus, we conclude that the area of the figure is 54 square inches.

Answer: 216 in²

Step-by-step explanation:

the area (A) of a rhombus is calculated as

A =  × d₁ × d₂ (d₁ and d₂ are the lengths of the diagonals )

the diagonals of a rhombus bisect each other , then

d₁ = 12 + 12 = 24

d₂ = 9 + 9 = 18

then

A =  × 24 × 18 = 12 × 18 = 216 in²

To Find:

Solution:

First, we have to find the Circumference of the Wheel:

As, we know:

[tex] \bigstar \:{\boxed{ \rm{Circumference_{(Circle)} = 2 \pi r }}} \: \bigstar[/tex]

where,

So, the Circumference of wheel will be:

[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} = 2 \times \frac{22}{7} \times 1.75 }}}} [/tex]

[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} = \frac{2 \times 22}{7} \times 1.75}}}}[/tex]

[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} = \frac{44}{7} \times 1.75 }}}}[/tex]

[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} = \frac{44 \times 1.75}{7} }}}}[/tex]

[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} = \frac{77}{7} }}}}[/tex]

[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} ={ \boxed{ \rm{ \red{11m}}}}}}}}[/tex]

Hence, the circumference of the wheel is 11m.

Now, we have to convert distance covered km into m:

[tex]{\leadsto{\large{\rm{ \: Distance \: Covered = 22km}}}}[/tex]

[tex]{\leadsto{\large{\rm{ \: Distance \: Covered =(22 \times 1000)m }}}}[/tex]

[tex]{\leadsto{\large{\rm{ \: Distance \: Covered = {\boxed{\rm{\red{22000m}}}}}}}}[/tex]

Hence, the distance covered is 22000m.

Now, we have to find the number of revolution:

Given:

According to the question by using the formula, we get:

[tex] \bigstar \: { \boxed{ \large{ \rm{Number \: of \: Revolution \: = \: \frac{Distance \: Covered}{Circumference }}}}}[/tex]

[tex]{ \large{ \longrightarrow{ \rm{Number \: of \: Revolution = \frac{22000}{11} }}}}[/tex]

[tex]{ \large{ \longrightarrow{ \rm{Number \: of \: Revolution = { \boxed{\red{2000}}}}}}}[/tex]

The number of 9 bright fringes is seen in the central maximum that spans the distance between the first missing order is 5 on one side and the first missing order on the other side

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

Blue laser light with a wavelength of 450 nm illuminates two 50-m-wide slits positioned 0.25 mm apart. On a screen 2.0 m behind the slits, the interference pattern is visible.

For dark fringe, the equation as:

yp = p  λ L / d

for p =1

yp = λ× L/a

For bright fringe, the equation as:

ym = m  λL / d

from (i) and (ii)

For missing order, the equation as:

ym = yp

m λL / d = λ× L/a

m=d/a

The probability that Nadia randomly picks up a reference book and then, without replacing it, picks up a nonfiction book is 5/136.

We have,17 total number books out of which,10 are fiction books, 2 are reference books, 5 are non-fiction books.

The combination is the number of ways of selecting things.

Probability is to quantify the possibilities.

Number of ways in which a reference book can be picked = ²C₁

Probability of picking a reference book = ²C₁ / ¹⁷C₁ = 2/17

Now, the total number of books left on the bookshelf is 16

The number of ways in which a non-fiction book can be picked after a reference book is already picked up( no replacement) = ⁵C₁ / ¹⁶C₁ = 5/16

Total probability =multiplication of both the possibilities

Total probability =(2/17)×(5/16) = 5/136

Therefore, the probability that she randomly picks up a reference book and then, without replacing it, picks up a nonfiction book is 5/136

If Carla plans to invest $9,000 for 10 years and  Better Bank offers a 10 year CD at an annual rate of 4% using simple interest. then investment will be worth $12600 .

What is simple interest?

Simple interest is based on the principal amount of a loan or the first deposit in a savings account.

Given that Carla plans to invest $9,000 for 10 years. Better Bank offers a 10 year CD at an annual rate of 4% using simple interest.

We know

A= PRT+ P =P(RT+1)

Where

A = Final amount,

P = Principal amount=9000

R = Annual interest rate in decimal form=0.04

t = Time in years=10

Final amount can be calculated as

[tex]&A=\$ 9000(1+0.04 \times 10) \\\\&A=\$ 9000(1+0.4) \\\\&A=\$ 9000(1.4) \\\\&A=\$ 12600\\[/tex]

The 90% confidence interval would be given by (63.330;81.070)

Step-by-step explanation:

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Let put some notation

x=left arm , y = right arm

x: 175 169 182 146 144

y: 102 101 94 79 79

Since the Confidence is 0.90 or 90%, the value of a = 0.1 and a/2= 0.05we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.05,4)".And we see that ta/2= 2.13

$30 and $24

Step-by-step explanation:

Hello! We can rewrite ratios as 5x:4x because essentially we can put x in for any value and it would still be the same ratio (10:8, 15:12). So we will put x there just to make it easier to understand.

You know that the ratio of 5x:4x adds up to 54. And, now that we have the x, we can do a nifty trick. We can add 5x and 4x to get 9x. Now we have 9x = 54. If we simplify this, we get x = 6.

Now that we have x = 6, we can plug in that value in the ratio 5x:4x. 5 * 6 = 30 and 4 * 6 is 24

And that is exactly your answer: 30 and 24 dollars respectively

If you want to test it, you can add the two numbers to see if it adds to the number you want it to. After that, you can put it in a ratio and simplify it to see if it simplifies down to the same ratio. In this case, the two numbers satisfy both conditions.
