Number 3 and how you got the answer

Answers

You have the correct steps and final answer. The area of the room is 196 square feet, so each side is sqrt(196) = 14. The perimeter is 14*4 = 56 feet. You'll need 6 boards (each 10 ft long) to get 60 ft total. You'll have 60-56 = 4 ft of board left over. This is assuming that there isn't any other type of waste or mistakes made in cutting.

Let C, S and H be the diameters of cell, sand and hair

Diameter of a cell: [tex] C=1 \cdot 10^{-5}m[/tex]

Diameter of a grain of sand: [tex]S=2 \cdot10^{-4}m[/tex]

Part A:

[tex]H=0.000025=2.5 \cdot 10^{-5}[/tex] meters, because it takes 5 movements right of the decimal dot, until there is only one digit to its left.

Part B:

we are comparing [tex]S=2 \cdot10^{-4} m [/tex] to [tex] C=1 \cdot10^{-5} m [/tex] ,

[tex] \frac{S}{C}= \frac{2 \cdot 10^{-4}}{1 \cdot 10^{-5}}=\frac{20 \cdot 10^{-5}}{1 \cdot 10^{-5}}=20[/tex]

thus S is 20 times larger than C

Part C

[tex]1m=1 \cdot10^9nm[/tex]

thus,

[tex]H=2.5 \cdot 10^{-5}m=2.5 \cdot 10^{-5} \cdot 1 \cdot 10^9nm=2.5 \cdot 10^{-5+9}=2.5\cdot10^4nm[/tex]

Part D.

[tex]1m=1\cdot 10^9nm\\\\1nm=\displaystyle{ \frac{1m}{10^9}=1\cdot 10^{-9}m} [/tex]

thus 300 nm are written in meters as follows:

Construct a function with a rate of change 2/3 and a initial value of 4.

Answers

If you recall y=mx+b, the slope-intercept form of a linear equation, the slope, m, is the rate of change of the equation, and the y-intercept is b.

When switching to function notation, we simply swap y for f(x), and if we start at x=0 and graph in the positive x direction, we've started at whatever initial value exists (the y-intercept value).

Simply: F(x) = 2/3 x + 4

The equation of the linear function will be y = (2/3)x + 4.

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

A function with a rate of change of 2/3 and an initial value of 4. Then the equation of the linear function is given as,

y = (2/3)x + 4

The equation of the linear function will be y = (2/3)x + 4.

The distance between Cameron and jonesville is 80 miles . the scale on the map is 0.75 in : 10 miles . How far apart are the cities on the map

Answers

It’s 6 on the map if you want me to explain message me

Answer:

6,751.76 miles

Step-by-step explanation:

Given

distance between Cameron and jonesville = 80 miles

scale on the map is 0.75 inches (10 miles)

To determine the Distance apart of the cities on the map we use a proportion

Therefore

Let x represent the distance apart

0.75 inches/10 miles = 80 miles/ x miles

Cross multiply

0.75x = 80 miles × 10 miles

x = 800 miles/0.75 inches

Convert 0.75 inches to miles = 1.184 × 10-5 mile

Therefore 800miles/1.184 × 10-5 mile

x = 6,751.76 miles

A scuba diver starts at 85.6 meters below the surface and descends until he reaches 103.2 meters below sea level. How many meters did he descend ?

Answers

188.8 meters because you have to add 103.2+85.6 = 188.8 meters

Final answer:

The scuba diver descended 17.6 meters.

Explanation:

To find the distance the scuba diver descended, subtract the starting depth from the ending depth. In this case, the starting depth is 85.6 meters below the surface and the ending depth is 103.2 meters below sea level. So, the distance the scuba diver descended is 103.2 - 85.6 = 17.6 meters.

Hollis and Charmaine are curious about which mode of transportation gets them from their apartment to the mall faster. Hollis takes public transportation and gets to the mall in 18.5 minutes. Charmaine rides her bike and gets to the mall in 0.5 hours. The mall is 2.4 miles away from their apartment. Use the formula for distance traveled, distance=rate⋅time, to find each rate of travel in miles per minute. What is the difference between Hollis' rate of travel on the bus and Charmaine's rate of travel on the bike? In other words, how much faster is it to take the bus in miles per minute? Enter your answer as a decimal, rounded to the nearest hundredth, if necessary, like this: 42.53 50 pts

Answers

Hollis travels 0.05 miles per minute faster than Charmaine. First, convert to the same units for both Hollis and Charmaine. So Hollis takes 18.5 minutes and Charmaine takes 0.5*60 = 30 minutes. Both girls travel 2.4 miles, so calculate how many miles per minute each takes Hollis = 2.4 / 18.5 = 0.13 miles per minute. Charmaine = 2.4 / 30 = 0.08 miles per minute. Finally determine the difference in speed between the two girls. 0.13 - 0.08 = 0.05 miles per minute.

complete the paragraph proof given: <1 and <2 are supplementary and <2 and <3 are supplementary Prove: <1 is congruent to <3

Answers

Angles <1 and <3 are proven to be congruent because they are both supplementary to the same angle <2, thus having the same measure as per the transitive property of equality.

When given that <1 and <2 are supplementary and that <2 and <3 are supplementary, we can prove that <1 is congruent to <3 through a series of logical steps. By definition, supplementary angles add up to 180 degrees. Therefore, if <1 and <2 are supplementary, we can write this as: m<1 + m<2 = 180 degrees (1). Similarly, if <2 and <3 are supplementary, that looks like: m<2 + m<3 = 180 degrees (2). By transposing m<2 from equation (1) to (2), we get m<1 = m<3, which implies that <1 is congruent to <3, as they have the same measure. This reflects the transitive property of equality where if a = b and b = c, then a = c. This conclusion demonstrates the Theorem 12, which states that if two angles are congruent to each other, their supplementary angles are also congruent.

The area of a square is 121 square inches.Find the perimeter

Answers

The sides are 11 each because the square root of 121 is 11. So, the permeter is 11 + 11 + 11 + 11 = 44 inches.

Hope this helped!

So the area of a square is length * width.

And the length = length.

So to find one side, just find the square root of 121.

The square root of 121 is 11.

So one side = 11.

Since there are four sides in a square,

11 * 4 = 44

So the perimeter is 44 inches.

8.8 545.6 mi

Answer:

Given : George is driving at an average speed of 62 miles per hour.

To Find : Write an expression that would give his distance traveled for h hours.

Solution:

Speed = 62 miles/hour

Time = h hours

[tex]Distance = Speed \times Time[/tex]

[tex]Distance = 62h[/tex]

So, an expression that would give his distance traveled for h hours is [tex]Distance = 62h[/tex]

Now we are supposed to Make a table that records his distance for 3, 5.5, 7, and 8.5 hours.

So, At h = 3

[tex]Distance = 62(3)[/tex]

[tex]Distance = 186[/tex]

So, At h = 5.5

[tex]Distance = 62(5.5)[/tex]

[tex]Distance = 341[/tex]

So, At h = 7

[tex]Distance = 62(7)[/tex]

[tex]Distance =434[/tex]

So, At h = 8.5

[tex]Distance = 62(8.5)[/tex]

[tex]Distance =527[/tex]

So, Table :

How does estimation help you place the decimal Point in a product correctly

Answers

That's easy when you estimate you are finding the whole number of which the decimal is closest to. When you place the decimal you count all the numbers behind the decimal point on the other numbers.

Then you move the decimal don that very spot.

Estimation helps to place the decimal point in a product correctly by counting the numbers of figures after the decimal points prior to finding the product, then shifting the decimal point from the back to the front in the order with which you've earlier counted it after the finding the product.

Estimation is used to approximate a large number of a particular number to its nearest whole number or significant figures.

The use of decimal points in estimation helps to separate the fractional part from the whole number.

For example, if we want to find the product of 4.23 and 2.1, we have three numbers altogether after the decimal point.

So;

4.23

× 2.1

4 2 3

8 4 6

8 8 8 3

So, starting from the back to the front, we will shift the decimal point in three places. Then the product of 4.23 and 2.1 is 8.883

Therefore, we can conclude that we've fully understood how estimation help you place the decimal Point in a product correctly.
