Marie has a small copy of rene magritte's famous painting, the schoolmaster. Her copy has dimensions 2 inches by 1.5 inches. The scale of the copy is 1 in :40 cm. Find the dimensions of the original painting

Answers

We just multiply the scale to the dimensions
2 in to original is: 2×40= 80 cm
or do proportions:
$(2)/(x)$ = $(1)/(40)$
= $(2*40)/(1)$ =x
=80 cm=x the original dimension.
Same thing to the other side.
1.5×40=60 cm
or proportions again:
$(1.5)/(y)$ = $(1)/(40)$
$(1.5*40)/(1)$ =y
60 cm=y
60 cm is the original dimension
80 cm times 60 cm ORIGINAL DIMENSION

Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer. 1 inch ≈ 1.578 × 10 -^5 miles.

Answers

Answer:

7.763×10^7 inches

Step-by-step explanation:

$(1225\,mi)(1\,in)/(1.578\cdot 10^(-5)\,mi)=(12.25)/(1.578)\cdot 10^(2-(-5))\,in \approx 7.763\cdot 10^7\,in$

When writing 1225 in scientific notation, it is convenient to choose an exponent so that the division result comes out with the right scale factor. It is easy to see that 1.2 < 1.6, so use of numbers with exactly one digit to the left of the decimal point would result in a fraction as an answer. We want the answer to have 1 digit left of the decimal point, so by scaling the operands to be 12. and 1.6, we get that result. Of course, the powers of 10 are adjusted accordingly.

This scaling process only matters if you're computing the results by hand. Any calculator can properly keep track of the required exponents.

"Back in the day" when slide rules were the calculating tool of choice, the operands and answer to any multiplication or division problem were only shown as 3 (sometimes 4) significant digits. All of the power-of-ten scaling was done "by hand" (usually, mentally). That is, the division would be 1225/1578 ≈ 776 × some scale factor. This is where thinking of the numbers as 12.25/1.578 = 7.76 comes in handy.

For a cone, if the radius was quadrupled and the slant height was reduced to 1/6 of its original size what would be the formula to find the modified surface area.

Answers

Let $r$ be the radius of the cone's base and $\ell$ the slant height.

The surface area of a cone is

$A=\pi r^2+\pi r\ell$

If the radius is quadrupled ( $r\to4r$ ) and the slant height scaled by a factor of $\frac16$ , then the new area is

$A=\pi(4r)^2+\pi (4r)\left(\frac\ell6\right)$
$A=16\pi r^2+\frac23\pi r\ell$

Identify all sets to which the number -3/4 belongsa. rational numbers
b. odd numbers, whole numbers, integers, rational number
c. whole numbers, integers, rational number

Answers

Answer:

a. rational numbers

Step-by-step explanation:

we observe that -3/4 is a proper fraction (i.e it is a rational number)

hence

1) It cannot be a whole number

2) it cannot be an integer

therefore any answer choices that mention whole number or integer is not correct. By default, only a is correct.

Final answer:

The number -3/4 can be found within the set of rational numbers. It does not belong to the sets of odd numbers, whole numbers, or integers, as these contain only whole numbers.

Explanation:

The number -3/4 is a rational number. Rational numbers represent any number that can be expressed as a fraction or ratio of two integers, with a non-zero denominator. Sets like odd numbers, whole numbers, and integers are part of number systems that include only whole numbers, and given that -3/4 is not a whole number, it does not belong in these sets. Therefore, from the given options, the correct one is: The number -3/4 belongs to the set of rational numbers.

Which property is illustrated by the equation (a+b)+c=c+(a+b)

Answers

Associative property of addition Which property is illustrated by the equation (a+b)+c=c+(a+b) is the associative property of addition. The associative property of addition groups addends together which still yields the same sum regardless of the clustering or grouping set.
For example:
1.           1 + (2 + 3) = 6 = (1 + 2) + 3
2.           1 + (2 + 7) = 10 = (1 + 2) + 7
3.           550 + (20 + 5) = 575 = (550 + 5) + 20
