1.8y-9.3y-6.3y hope you can help

Answers

8y - 9.3y - 6.3y = -7.6

The answer is -13.8y

First subtract 1.8y from 9.3y which is 7.5y, but since you are actually subtracting a larger number from a smaller number, you add a negative sign because your answer is less than 1. Then you add -6.3y to to -7.5y because you have two negatives. While it may seem like you should add them, you will subtract because you are adding essentially more negative to the negative number. I hope that makes sense! Once you add -6.3y to -7.5y your answer is -13.8y.

Tomas works as an underwater photographer. He starts at a position that is 19 feet below sea level. He rises 9 feet, then descends 16 feet to take a photo of a coral reef. Enter an expression to find his position relative to sea level when he took the photo and then evaluate the expression.

Answers

19=9-16 would probably be something to go off of and begin your thought process with.

Answer:

Expression:

X = Xo + 9 feet - 16 feet
X = - 19 feet + 9 feet - 16 feet
X = - 26 feet (26 feet below the sea level)

Explanation:

1) Call Xo the initial position, and X the variable to indicate the actual position

2) Use position 0 for sea level

3) use negative sign for positions under the sea level

4) use positive sign for positions above the sea level

5) Expression:

Final position = initial position + movements upward - movements downward

X = Xo + 9 feet - 16 feet

X = - 19 + 9 feet - 16 feet = - 26 feet

Begin with {5000,0} to represent the starting amount of money and years passed. Hit enter. Then, put in: {Ans(1)x1.06,Ans(2)+1}.
The first part adds the compounded interest and the second adds a year.

Olivia ate 1/4 of a pizza if there were 12 slices of pizza how many slices did Olivia eat

Answers

Hello!

There are many ways you can solve this question. I'll show you a few. Way 1:

Convert 1/4 to a decimal by dividing its numerator by its denominator.

1 ÷ 4 = 0.25

1/4 is 0.25 as a decimal.
Then, multiply the amount of slices of pizza by the decimal form.

12 × 0.25 = 3

Way 2:

Since the numerator is 1, simply divide ths number of slices by the denominator of the fraction. You will get the same answer.

12 ÷ 4 = 3

ANSWER:

Olivia ate 3 slices of pizza.

Madame Pickney has a rather extensive art collection and the overall value of her collection has been increasing each year. Three years ago, her collection was worth $400,000. Two years ago, the value of the collection was $440,000 and last year, the collection was valued at $484,000. Assume that the rate at which Madame Pickney’s art collection’s value increase remains the same as it has been for the last three years. The value of the art collection can be represented by a geometric sequence. The value of the collection three years ago is considered the first term in the sequence. What explicit rule can be used to determine the value of her art collection n years after that?

Answers

The rule you would use to represent the situation would be 400,000 + 40,000x. X would represent the number of years that have passed since the amount has been increasing at the same rate. You could use this expression to find her value of the art collection if you know how many years have passed since the constant rate began.

12 is 36 less than 4 times a number. What is the number?

Answers

The answer is twelve (12).
Let us use this equation: 4x-36= 12
x stands for the missing number.
To solve for x, we will transfer the -36 to the side of 12, and it will look like this: 4x= 12+36 (NOTE: Once we transfer a number on the other side, their signs will change too. For example, the -36 became positive 36 when it was transferred to the side of the 12)
Then, 4x= 48, divide both sides by 4 so that the x will remain. 48/4= 12.
Therefore, x=12

Let

x---------> the number

we know that

[tex]12=4x-36[/tex] ---------> equation [tex]1[/tex]

Solve for x

Which set of statistics best describes a typical home value in Maya's neighborhood and how the values vary?

Answers

The answer is the median and the interquartile range. When you have data that is skewed ( more data points on one side or another, than the median is a good measure as well as the range of the middle half of the data (interquartile range -IQR).

Answer:

The typical home value is best described by the median.

The value variation is best described by IQR.

Step-by-step explanation:

For samples of data that have outliers, the set of statics that best describes central tendencies are the robust measures.

The median is a robust measure because the outliers will have very little impact on the result of the measure.

The IQR is a robust measure because it takes the difference between the 75th percentile and the 25th percentile of a sample, so the outliers are ignored.

Explain a scenario where you would use a frequency table to display data in the real world.

Answers

Many people have no occsasion to collect data in the real world. One basically has to dream up scenarios in which data collection might be desired, then sort through those to see if a frequency table would be of any value.

Some manufacturing processes produce parts that have a wide range of characteristics. Sometimes the range is much larger than is desired for a particular purpose, so the parts are "binned". That is, if they have characteristics in a specific narrow range, they are put into a bin with other similar parts.

Some customers want only parts with a particular specific characteristic (color or brightness, for example). If a request for quote comes that asks for a large number of these parts, it would be helpful to have on hand previously collected data about the percentage of production that falls into the specific bins desired. That is, a frequency table showing the number in each bin produced by a given operator, machine setting, environmental condition, material supplier, or other variable would be very helpful information when responding to the customer.

My sister is buying new carpet for her bedroom floor. The length of the bedroom is 13 feet. The area of the bedroom is 175.5 square feet. How wide is my sister's bedroom?

A. 13.5 ft

B. 13.5 ft 2

C. 162.5 ft 2

D. 198.5 ft 2

Answers

Since the formula for the area of a rectangle is length × width = height, we can divide the area by the length to get the width.

175.5 ÷ 13 = 13.5

And since the width is one dimensional, the answer is A.

Hope this helps!

Area = length x width
Given: length = 13 , area = 175.5

175.5 = 13 x width
width = 175.5 ÷ 13
width = 13.5 feet

The width is 13.5 ft (Answer A)

Jillene wrapped 4 gifts for her 4 cousins. If she gives them out randomly, what is the probability that every cousin gets the right present?

Answers

The possibility is 1/4 (1 out of 4)

Jillene wrapped 4 gifts for her 4 cousins. If she gives them out randomly, then there are 4! ways in which her cousins can receive the gifts.

Now, we know that 4!=4 x 3 x 2 x 1=24

Thus, if Jillene gives out her 4 wrapped gifts randomly to her 4 cousins, then there are 24 ways in which her cousins can receive Jillene's gifts. But there is only one way in which every cousin gets the right present.

Thus, the probability, P, that every cousin gets the right present is:

[tex] P=\frac{1}{24} [/tex]

Expressed as a percentage the probability, P is approximately, 4.17%

Suppose you borrow $1,200 at an add-on interest rate of 5% for 4 years. What will be the amount of your monthly payment ?

Here P is the Principal ,r is the rate of interest and t is the formula .

In the given question P=$1200 ,r=5% ,t= 4 years.

Substituting these values in the formula

[tex] A=1200( 1+\frac{5}{100} )^4 [/tex]

[tex] A=1200(1.05)^{4} [/tex]

The length of a rectangular floor is 4 ft. longer than its width w. The area of the floor is 525 ft^2.
a) Draw a picture of the situation.

b) Write a quadratic equation for the area in terms of w that represents the situation.

c) What are the dimensions of the floor? Explain how you found them.

Answers

Answer: The dimensions of the floor are 21 by 25.

For your drawing, you will have a rectangle with an x for the width and an x + 5 for the length.

If we multiply those together, we get the following equation for the area.
x(x + 5) = A
x^2 + 5x = A

Now, input 525 and solve for x.
x^2 + 5x = 525
x^2 + 5x - 525 = 0
x = 21 or x = -25

Only 21 makes sense for the width. Adding on 4 gives us 25 for the length.

Assume that the width of the floor is w.
The length is 4 ft longer than the width.
This means that:
Length = 4 + w

Part (a):
The drawing of the situation is shown in the attached image

Part (b):
Area of the rectangle is calculated as follows:
area = length * width
area = (w + 4) * w
area = w² + 4w
We are given that the area is 525 ft²
This means that:
525 = w² + 4w

Part (c):
To get the dimensions of the floor, we will need to solve the quadratic equation from part b.
area = w² + 4w
525 = w² + 4w
w² + 4w - 525 = 0
(w-21)(w+25) = 0
either w-21 = 0 ............> w = 21 ft .........> accepted solution
or w+25 = 0 ............> w = -25 ...........> rejected solution as the length cannot be negative
Now, we know that:
length = w + 4
length = 21 + 4
length = 25 ft
This means that:
length of floor = 25 ft
width of floor = 21 ft

Hope this helps :)

The equation 5x-10y=30is written in standard form. What is the first step when solving for x? Add 5x to both sides of the equation. Subtract 5x from both sides of the equation. Add 10y to both sides of the equation. Subtract 10y from both sides of the equation.

Answers

you would have to add 10y to both sides, and then divide by 5

The first step is Add 10y to both sides of the equation.

What is equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Parts of an Equation

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.

An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables.

Given:

5x- 10y =30

Now, to solve for x we must contain 'x' till the last step

so, we have to remove variable y

Then, Add 10y to both sides of the equation is the first step.

5x - 10y + 10y = 30 + 10y

5x = 30 +10y

Hence, Add 10y to both sides of the equation.
