If one inch represents 8 feet, what dimensions would you use to make a scale drawing of a building 34 feet by 75 feet?

Alex

4 inches by 9.375 is the answer because you divide the both numbers by 8

The scatterplot to the left shows the cost, C, in thousands of dollars, and living space, z, in square feet (ft) for several hou

Andreyy89

Answer:

f(x) = -22.45x^2 + 92.38x + 1.86

Because the points on the scatter plot show an increase in concentration from 0 hours through 2 hours and a decrease from 2 hours through 4 hours, the relationship shown is best modeled using a quadratic function.

Let's look closely at the two quadratic function choices to determine the key features of their graphs.

Because the coefficient of its x^2 -term is negative, the graph of f(x) = -22.45x^2 + 92.38 + 1.86 will be concave down and have a maximum value.

Because the coefficient of its x^2 -term is positive, the graph of f(x) = 22.45x^2 + 92.38 + 1.86 will be concave up and have a minimum value.

Because the scatter plot shown has a concave down trend, the function that best describes the relationship shown is:

f(x) = -22.45x^2 + 92.38 + 1.86

Value of x, of (18, 24, 22, 28,x) mean =25

tankabanditka [31]

Answer:

x = 33

Step-by-step explanation:

Mean = Sum of all the data's/ Number of data's

$\frac{18+24+22+28+x}{5}=25\\\\\frac{92+x}{5}=25\\\\92+x=5*25\\\\92+x=125\\\\x=125-92\\\\x=33$

Hey I’m doing a project but I don’t get it at all but overall we’re doing a project about buying a home the estimate price of my

astraxan [27]

Answer:

$14,500

Step-by-step explanation:

There is a lot of information that is extraneous to answering this question (although it may be useful for answering later questions, as it looks like this is a multi-part question).

This question simply requests "Calculate the down-payment for the 30-year fixed mortgage."

So, we're focusing on the down-payment on the 30-year mortgage.

The paragraph immediately above the question states "Suppose you decide to make a down-payment of 5% of the purchase price for the 30-year fixed mortgage..." ... there's other information, but it's about mortgages that aren't 30-year mortgages, so we can safely ignore it.

The first paragraph in the picture shows information about a standard down payment (20%), and what happens if you decide to choose a down-payment that is less than standard (that's us... we chose 5% ... so let's pay attention closely here).

The information states that "...lenders charge extra... PMI that is added to the monthly payment." Note, that extra charge (PMI) is added to the monthly payment, not the down-payment. So, this information about PMI doesn't apply to the question in part (a).

So, for this question, the down payment is simply 5% of the purchase price.

Percentages can be interpreted as the # of parts out of 100, so in this case 5 out of 100, which is just another way of saying $\frac{5}{100}$ . Fractions, in turn, can be turned into decimal numbers simply by dividing the two, which gives 0.05. Many people interpret this simply as moving the decimal place on the percentage two digits to the left. In short, 5% = 0.05.

To find 5% of the purchase price, we simply multiply it to the purchase price, but we choose a form that is more conducive to doing the arithmetic, so either the fraction 5/100, or the decimal 0.05 (usually the decimal).

Given a purchase price of $290,000, 5% of $290,000 is

$0.05*\$290,000=\$14,500$
