Sale price is $75 it was 20% off what was the original price

Answers

Since it was 20% off, 75% is 80% (100-20) of something. We then want to find 10%, and multiply that by 10 to find the original price. Since 10% is 1/8th of 80, we divide 75 by 8 to get 9.375. Multiply that by 10 to get 93.75 dollars, the original price

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.

---------
28,572

Multiplying 4762 by 33 through long multiplication involves multiplying 4762 by 3 and 30 separately, then adding the results to get the final answer of 157146.

To multiply 4762 by 33, you use long multiplication:

Multiply the number 4762 by 3 (the ones place of 33). Write the result under the line.Multiply the number 4762 by 3 again (this time because of the tens place in 33), and write this result one place to the left of the previous result.Add both results together to get the final answer.

Step-by-step:

      4762
 x      33
 ---------
    14286   (4762 x 3)
+ 14286     (4762 x 30, note the one place shift)
 ---------
   157146   (addition of both results)

Thus, 4762 multiplied by 33 equals 157146.

How to solve y^2=144/169

Answers

Find the square root of both sides
√y²= √(144/169)

y= √144 / √169
y= 12/13

Final answer: y=12/13

The solution to the equation y^2 = 144/169 yielding two possible solutions for y which are 12/13 and -12/13.

Step 1: Take the square root of both sides of the equation to get y. Remember that taking the square root of a square will provide you with the original value. However, since every positive real number has two square roots, one positive and one negative, your answer will have two potential values.

Step 2: The square root of 144 is 12, and the square root of 169 is 13, thus the equation becomes:

y = ± (12/13)

Therefore, the two solutions to the equation are y = 12/13 and y = -12/13.

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.

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

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.

ben is making a dessert that requires 2.5 pound of strawberries and 1.5 pounds of blueberries. The straw berries cost $1 less per pound. Ben paid a total of $9.50 on the fruit what was the price per pound of each fruit?

2.5(y - 1) + 1.5y = 9.50
2.5y - 2.5 + 1.5y = 9.50
2.5y + 1.5y = 9.50 + 2.50
4y = 12
y = 12/4

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.

                     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 :  

      Hours                  Distance (miles)

        3                             186

       5.5                           341

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:

[tex]300nm= 300\cdot 1\cdot 10^{-9}m=3\cdot 10^2 \cdot 10^{-9}m=3\cdot 10^{-7}m[/tex]
