So , there is this thing that says : "the circumference of a circle is 7,850 , whats the radious?

Answers

Answer:

1250 (corrected to 3 significant figures)

Step-by-step explanation:

the formula to calculate circumference is 2πr, where r is the radius.

hence, we can form the equation

2πr = 7850

r ≈ 1249.3663

= 1250 (corrected to 3 significant figures)

a) 4/3
b) 3/4
c) -3/4
d) -4/3

Answers

Answer:

3/4

Step-by-step explanation:

Since we have two points, we can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 5 - -1)/( 4 - -4)

   = ( 5+1)/(4+4)

   = 6/8

Find the slope of the graph

Answers

Answer: The slope of the graph is -2

Step-by-step explanation:

Take any two points from the graph, and do rise/run

For example, we take (1,3) and (2,1)

Apply rise/run... rise: 2, run: -1

2/-1 = -2

m = -2

For the next question, the slope is 4

And the last question, the slope is 1 1/2

Model the following verbal description below with an equation, Table, and graph. The table must include at least five data points. The table must include at least five data points. The basketball team wants to order shirts for the game days. The t-shirt company charges a $5 flat rate for using their services and $2 for every letter on the shirt.

Modeling of a situation is getting its properties held in another system, usually mathematical. The equation for given situation is [tex]C = 2T + 5[/tex]

How to form mathematical expression from the given description?

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For the given case the number of t-shirts brought is not known, so let we take it as T

Since each t-shirt costs $2, thus, T t-shirts will cost: T × $2

Since, cost of using the service of the t-shirt company is $5 flat rate, thus,

Total cost for purchasing T t-shirts = T × $2 + $5

Let total cost be denoted by C, then:

[tex]C = 2T + 5[/tex]

(we usually  don't write multiplication sign usually, and write the quantities close to each other, denoting that they're in multiplication.)

(we usually don't write symbols like $ etc in equations. It is known from context like what type of currency is in discussion(if multiple currency, then we can do some modification to variable symbols).

Thus,

The equation for given situation is [tex]C = 2T + 5[/tex]

Table for it, using values of T from 1 to 5, we get:

[tex]\begin{array}{cc}T&C\text{(In dollars)}\\1&7\\2&9\\3&11\\4&13\\5&15\end{array}[/tex]

Plotting them in graph, we get the following attached graph.

A construction company takes 1 3/8 hours to remove 2 1/2 metric tons of dirt from a construction site. What is the unit rate in metric tons per hour? Write your answer as a fraction or a mixed number in simplest form.
PLEASE HELP!! NO LINKS PLZ

Answers

Answer:

  1 9/11 T/h

Step-by-step explanation:

You want the unit rate in metric tons per hour of removal of 2 1/2 metric tons in 1 3/8 hours.

Unit rate

The unit rate in tons per hour is found by dividing tons by hours:

  (2 1/2 T)/(1 3/8 h) = (5/2 T)/(11/8 h) = (20/8 T)/(11/8 h) = 20/11 T/h

 = 1 9/11 T/h

The unit rate is 20/11 metric tons per hour, or 1 9/11 metric tons per hour.

What prism or other 3-dimensional shape would you use to model the tree trunk below? (Rectangular prism, triangular prism, square prism, or cylinder). If the height of the tree trunk is 13 ft and the radius is 1.5 ft, what is the volume in cubic feet?

Answers

Answer:

cylinder91.9 ft³

Step-by-step explanation:

a)

An object with a uniform circular cross section is generally modeled by a cylinder.

__

b)

The formula for the volume of a cylinder is ...

  V = πr²h

For the given radius and height, the volume is ...

  V = π(1.5 ft)²(13 ft) ≈ 91.9 ft³

The volume of the tree trunk is about 91.9 ft³.

I need AC

Answers

Answer:

AC = 18

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{AC}{12\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2 AC = 12[tex]\sqrt{3}[/tex] × [tex]\sqrt{3}[/tex] = 12 × 3 = 36 ( divide both sides by 2 )

AC = 18

∠ACB=90° ⇒ ΔABC is right triangle

AB is hypotenuse, ∠BAC=30° ⇒

[tex]CB=\dfrac{AB}{2}=\dfrac{12\sqrt{3} }{2} =6\sqrt{3}[/tex]

Let's use Pythagorean theorem

[tex]AB^2=BC^2+AC^2\\AC^2=AB^2-BC^2\\AC^2=(12\sqrt{3})^2-(6\sqrt{3} )^2\\AC=\sqrt{(12\sqrt{3}-6\sqrt{3})(12\sqrt{3}+6\sqrt{3}))} \\AC=\sqrt{6\sqrt{3}\times18\sqrt{3} } \\AC=\sqrt{3\times6\times18} \\AC=18[/tex]

What is the main difference between multiplying decimals and whole numbers? If one factor has 2 decimal places and another factor has 1 decimal place, how many decimal places will the product of these two factors have?

Answers

Answer:

Both type of  numbers have a decimal point but the decimal numbers can contain digits other than 0 so you have to worry for these numbers when you're multiplying and the placement of the decimal point in the answer.

A way think about it is sum the total numbers after the decimal point, this work because the numbers can be represented as fractions (explanation below) so If one factor has 2 decimal places and another factor has 1 decimal place the answer have 3 decimal places.

Step-by-step explanation:

A whole can be represented as 2 and so on, while a decimal number is represented as 3.14 when the numbers after the decimal point can be different of 0.

So when you multiply two decimal numbers check the total number of number after the decimal point and sum these amounts.

Where the total number of numbers after the decimal point is equal to the power of 10 in the denominator that's mean equal to 3. However this method takes more time, so is more simply to say that the total of numbers after the decimal point is the sum of the total of numbers after the decimal point of each decimal number.

Answer:

C. 1725

Step-by-step explanation:

We can find the selling price by adding the cost price and the profit made

As the merchant has made 15% of profit on 1500 birr . So ,

15% of 1500 is 225 birr

[tex] \frac{x}{1500} \times 100 = 15 \: percent[/tex]

Adding the cost price and profit made we get ,

Selling Price = 1500 birr + 225 birr
