Kelly enlarged the area of a photograph to 250% of its original size. The original dimensions of the photograph were 5 inches by 7 inches. What is the area of the enlarged photograph, in square inches? A) 71.25 B) 87.5 C) 218.75 D) 3,000

Answers

Answer 1

Answer:

The area of the enlarged photograph is 87.5 square inches.

What is the area of the enlarged photograph?

The first step is to determine the area of the photograph before it was enlarged. A photograph has the shape of a rectangle. So, the formula for the area of a rectangle would be used.

Area = length x width = 7 x 5 = 35

Area of the enlarged photograph = 2.5 x 35 = 87.5

Answer 2

Answer:

Answer:

answer is B) 87.5 squared inches.

Step-by-step explanation:

The original dimensions of the photograph were 5 inches by 7 inches so, the area of the original photograph can be computed as the area of a rectangle:

$Area=(heigh)(base)$ .

$Area=(5)(7)$

$Area=35$ squared inches.

Now, for computing the area of a photograph of 250% the size of the original we use a simple rule of three:

35 squared inches -------- 100%

X squared inches --------- 250%

By this, we have:

$X = ((35)(250))/(100)$

$X = 2.5*35$

$X = 87.5$

How many angles does a cube have?

Answers

A cube is a geometric three-dimensional solid object. It constitutes 6 square faces, sides and three meeting at each vertex. It is the only regular hexahedron. A cube has a fixed number of perpendicular angles. Typically, it has 8 perpendicular angles and each spigolo or corner has 3 angles. Since it has 8 perpendicular (⊥) angles and 3 angles in each corner, it makes up 24 angles.
All 8 ⊥ angles and 3 angles in each corner mean: 8*3=24.

Therefore, a cube has 24 right angles.

Benford’s law states that the probability that a number in a set has a given leading digit, d, isP(d) = log(d + 1) - log(d).

State which property you would use to rewrite the expression as a single logarithm, and rewrite the logarithm. What is the probability that the number 1 is the leading digit? Explain.

Answers

Benford’s law states that the probability that a number in a set has a given leading digit, d, is
P(d) = log(d + 1) - log(d)
The division property of logarithm should be use to make it as a single logarithm
P(d) = log ( (d + 1)/ d)
So the probability that the number 1 is the leading digit is
P(1) = log ( ( 1+1)/ 1)
P(1) = log ( 2)
P(1) = 0.301

The probability that the number 1 is the leading digit is $0.301$ .

Given information:

Benford’s law states that the probability that a number in a set has a given leading digit $d$ , is $P(d) =\log(d+1)-\log(d)$

As mentioned in question,

Probability of a number in a set is given by $P(d) =\log(d+1)-\log(d)$ .

The division property of logarithm should be use to make it as a single logarithm $P(d)=\log((d+1)/(d))\;\;\;\{\log(a)-\log(b)=\log(a)/(b)\}$ .

So, the probability that the number 1 is the leading digit is,

$P(1) = \log ( ( 1+1)/ 1)\nP(1) = \log ( 2)\nP(1) = 0.301\n$

Hence, The probability that the number $1$ is the leading digit is $0.301$ .

Henry divides 1.060 g by 1.0 mL to find the density of his water sample. How many significant figures should he include in the density value that he reports?

Answers

2 Significant figures should be include in the density value that Henry reports.

What is Significant figure?

" Significant figure are those digit of number which are important in terms of accuracy. They are single digit number from 0 to 9, which express the message of accuracy."

According to question,

Henry divides 1.060g by 1.0mL

1.060 has 4 significant figure

1.0 has 2 significant figure

As per division rule of significant figure

When we divide two more numbers, count the significant figure of the given number. Least is the significant figure of the concluded one.

Here 2 is the lowest among two.

Hence, we conclude that 2 Significant figures should be include in the density value that Henry reports.

#SPJ2

1.060 g has 4 sig figs
1.0 mL has 2 sig figs

When dividing use the smaller amount of significant figures, so the density should be to 2 sig figs
