Answer:

Multiples of 9 are 9,18,27,36,45.

Multiples of 32 are 32,64,96,128,160

Prime numbers are 2, 3, 5, 7, 11,

Hope this helped

Answer 2

Answer:

a) 9, 18, 27, 36, 45 b) 1, 2, 4, 8, 16, 32 c) 2, 3, 5, 7, 11

Step-by-step explanation:

a) To find the first five factors, you just need to multiply nine by 1, 2, 3, 4, and 5 and there are your answers :)

b) 1x32=32, 2x16=32, and 4x8=32, but none other whole numbers can multiply to get 32. So those are the factors of 32.

c) Prime numbers are ones who's only factors are 1 and themselves. 2, 3, 5, 7, and 11 are the first of the list because you will not find any other factors.

Chase is conducting A survey at school to see what their favorite subject is. He surveyed of 25 students from his math class. He found that 75% of the students in math what is their favorite subject. Is this a valid inference? Why or why not? Explain your answer to complete sentences.

Talon Middle School received 219 prize packs. The school gave away f packs during school fundraisers. There were 42 packs passed out during pep rallies throughout the year. At the end of the year, the school had 54 prize packs left. How many packs were passed out during the fundraiser?

Answers

Answer:

123

Step-by-step explanation:

219 - 42 = 177 left

177 - f = 54

f = 177 - 54

f = 123 packs were passed out during the fundraiser

123

Step-by-step explanation:

219-42=177

177-54=123 or (f)

Check your work:

219-42=177

177-123=54

Therefore f=123 or 123 packs were passed out during the fundraiser.

Answer: The inverse of f(x) is not g(x).

Step-by-step explanation:

Steps taken:

Swap x and y variablesSolve for yProve that the equations of f'(x) and g(x) are identical.

1.

[tex]f(x) = x + 10\\y = x + 10\\x = y + 10[/tex]

A total of 544 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?

Answers

Answer:

x=136

Step-by-step explanation:

So lets say x is the number of pencils so, the number of erasers = 544-x

The equation is then 3x = 544-x  & x=136

Answer: 136 adult tickets

Step-by-step explanation: If you have 136 adult tickets then you have to multiply that by three in order to get the child tickets. 136 x 3 = 408 and 408 + 136 = 54

What is the positive solution to the equation 0 = –x2 + 2x + 1? Quadratic formula: x = StartFraction negative b plus or minus StartRoot b squared minus 4 a c EndRoot Over 2 a EndFraction –2 + StartRoot 2 EndRoot 2 – StartRoot 2 EndRoot 1 + StartRoot 2 EndRoot –1 + StartRoot 2 EndRoot

Answers

Answer:

See attached for a "Neat" quadratic formula.

a = -1

b = 2

c = 1

x = [-2 +- sqr root( 4 -4*-1*1)] / -2

x = [-2 +- sqr root( 4 -4*-1*1)] / -2

x = [-2 +- sqr root(8)] / -2

x1 = (-2 +2.8284271247)  / -2

x1 = .8284271247 / -2

x1 = -0.41421

x2 = (-2 -2.8284271247)  / -2

x2 = ( -4.8284271247)  / -2

x2 = 2.4142135624

So the equation has the positive solution of

Complete the following sentence about the rate of change in the tiger population. Round your answer to two decimal places
two decimal places.

The tiger population loses 3/5 of its size every ______ decade.

Answers

Answer:

0.33 decades

Step-by-step explanation:

The tiger population loses 3/5 of its size every 0.333 decades.

What is an Exponential Function?

An exponential function is what can be represented by the equation

y = aˣ

The number of tigers N(t) has been modeled by the equation

[tex]\rm N(t) = 710 * (\dfrac{8}{125})^t[/tex]

The tiger population loses 3/5th of its size in how much decade has to be found.

if it loses 3/5, the remaining will be 3/5 of the size so,

[tex]\rm \dfrac{2}{5} * 710 = 710 * (\dfrac{8}{125})^t\\\\\\dfrac{2}{5} = (\dfrac{8}{125})^t\\[/tex]

Taking log on both the sides

ln 2 - ln 5 = t( ln 8-ln 125)

t= 0.333

Therefore, the tiger population loses 3/5 of its size every 0.333 decades.

What is the wavelength of a 320 Hz sound traveling 330 m/s?

Answers

Answer:1.03125 meter

Step-by-step explanation:

Velocity =330 meter per second

Frequency =320 Hertz

wavelength=velocity ➗ frequency

Wavelength=330 ➗ 320

Wavelength=1.03125 meter

Answer:

1.03 meters

Step-by-step explanation:

Answer:1.03 meters

Step-by-step explanation:

Solving for wavelength

wavelength formula--->wavelength= velocity / frequency

velocity= 330 m/s

frequency= 320 Hz

Wavelength=330 / 320

330/320=1.03125

rounded up to 1.03

Wavelength=1.03125 meters or 1.03

Given Event A, Event B, and Event C. Event A and Event B are mutually exclusive. Event A and Event C are not mutually exclusive.
P(A) = 0.15
P(B) = 0.35
P(C) = 0.55
What is the probability of the complement of Event B?
0.85
0.35
0.65
0.45

Answers

Answer:

0.35

Step-by-step explanation:

The probability of the complement of Event B is equal to 0.65. so option C is correct.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

Given;

Event A and Event B are mutually exclusive.

We have given data

P(A) = 0.15

P(B) = 0.35

P(C) = 0.55

We need to find the he probability of the complement of Event B.

The formula for the compliment of the event

P( B⁻ ) = 1 - P( B)

Use the given value in the above formula we have,

=  1 - 0.35

= 0.65

The probability of the complement of Event B is equal to 0.65. so option C is correct.

What is the final transformation in the composition of transformations that maps pre-image GHJK to image G'H"J"K"? a translation to the right a reflection across line m a 90° rotation about point G a 180° rotation about point G

Answers

Answer:

a reflection across line m answer is b

Step-by-step explanation:

A reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K". Option B is correct.

The final transformation is to determine that transition states have been shown in the image that describes how pre-image GHJK transformed to image G'H"J"K".


What is reflection?

Reflection is defined in an atmosphere as when the beam of light or wave strikes to the plane or curved surface deviates back from the atmosphere.

Steps of Transformation
Pre-image GHJK first rotates anticlockwise by an angle of 90° to G'H'J'K'.
Then G'H'J'K' reflected across the line m to G'H"J"K". It is the final transition state.


Thus, a reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K".

Your savings account pays 2.5% interest per year. How much interest does the account pay per month.

Answers

Answer:

0.21%

Based on the interest that your savings account pays per year, the interest paid per month is 0.21%.

How much interest is paid per month?

The interest paid per month can be found by dividing the yearly interest by the 12 months of the year.

Therefore, solving gives:

= Annual interest / 12 months

= 2.5% / 12

= 0.21%
