Heron's Formula:




In geometry, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle by requiring no arbitrary choice of side as base or vertex as origin, contrary to other formulas for the area of a triangle, such as half the base times the height. Use Heron's formula to find the area, in square centimeters, of ΔABC.

Answer:

Step-by-step explanation:

The slope of the line is "rise"/"run". Here, the "run" is given as (27 s -12 s) = 15 s. So, we have ...

  (change in distance)/(15 s) = -4/5 m/s

  change in distance = (-4/5 m/s)(15 s) = -12 m

The ride descended 12 meters in the time indicated on the graph.

__

Again, the slope is "rise"/"run".

  65 mi/h = (318 mi -123 mi)/(travel time)

  travel time = (195 mi)/(65 mi/h) = 3 h

The car took 3 hours to get from 123 miles to 318 miles.

C) x – 3 ≥ 6

Solving this inequality by adding 3 on both sides, we get

x ≥ 9 which is shown on the number line

Answer:

Estimate: 21,000 or 21,300 (the answer depends on what your teacher is looking for. you didnt give a lot of information so i apologise if its wrong)

Exact: 24,072

Step-by-step explanation:

Estimate -

700 x 30 = 21,000

or

710 x 30 = 21,300

Answer:180

Step-by-step explanation:

you start by finding the prime factorization of the number

5=1*5

9=3*3

12=2*2*3

the shortest way to find the factors is to find is most of them like example, at max, there are 2 two's, 2 three's and 1 five then you multiply them all together

4*9*5=180 and that's the answer

Answer:

180

Step-by-step explanation:

Answer: The scatterplot is shown below.

Explanation:

Each row in the table represents a different (x,y) point.

For example, the first row says that x = 2 and y = 1. We'll have a point at (2,1) on the graph. This means we start at the lower left corner which is the origin. Then we move 2 units to the right and 1 unit up to arrive at (2,1). The other rows are handled in a similar manner to get what you see below. The points are not connected with any line or curve. The labeling of A,B,C, etc is optional. I did it to help keep track of all the points in the table.

Answer:

80 glasses

Step-by-step explanation:

640/8 = 80

Answer: 80 glasses

There are 80 glasses of lemonade can be poured from the dispenser if each glass holds 8 ounces.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

A large drink dispenser used at a school field day holds 640 ounces of lemonade.

Now,

Find the number of glasses of lemonade can be poured from the dispenser if each glass holds 8 ounces as;

= 640 ÷ 8

= 80

Thus, There are 80 glasses of lemonade can be poured from the dispenser if each glass holds 8 ounces.

Answer:

numbers are 24 and 210

Step-by-step explanation:

the number are : 24(2x2x2x3) and 210 (3x2x5x7)

GCF of 24 and 210 is 6

LCM of 24 and 210 is 840

9514 1404 393

Answer:

  a. numbers: 24, 210

  b. GCF = 6

  c. LCM = 840

Step-by-step explanation:

The number each circle represents is the product of the factors in that circle:

  red circle: 2×2×2×3 = 24

  blue circle: 2×3×5×7 = 210

The numbers represented in the diagram are 24 and 210.

__

The GCF is the product of the common factors--the factors in the portion of the diagram where the circles overlap:

  GCF = 2×3 = 6

__

The LCM is the product of all of the factors shown in the diagram:

  LCM = 2×2×2×3×5×7 = 840

_____

Additional comment

I personally find this a nice way to represent two numbers, their GCF, and their LCM. Note that there cannot be any numbers in the red (only) part of the diagram that are also in the blue (only) part of the diagram. Any common factors belong in the overlap portion of the diagram.

This diagram makes it easy to see that the LCM is the product of the numbers, divided by their GCF. (The product of the two numbers will have the center portion of the diagram appear twice in the product. It only appears once in the LCM.)

Answer:

336 employees

Step-by-step explanation:

Hi there!

We're given:

Ratio of men to women ⇒ 5:7

Number of women in the company ⇒ 196

1) Solve for the number of men in the company

Set up a proportion

[tex]\displaystyle \frac{5}{7} = \frac{x}{196}[/tex] where x is the number of men working at the company

Multiply both sides by x

[tex]\displaystyle \frac{5}{7} *196= x\\\\x=140[/tex]

Therefore, there are 140 men working at the company.

Now, we know that there are 140 men and 196 women working at the company. Assuming that they are the only people who work there, the total number of employees is 140 + 196 = 336.

I hope this helps!

Answer:

336 total employees

Step-by-step explanation:

divide women by their respective ratio to get unit multiplier

196÷7=28

add the 2 numbers in the ratio to get both men and women

7+5=12

multiply everyone by unit multiplier

12(28)

The fewest number of miles that Ori needs to drive before the mileage shows three identical digits again is 40.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We have been given that the mileage on Ori's car is 73,033 miles.

We need to find the fewest number of miles that Ori needs to drive before the mileage shows three identical digits again.

Therefore, the mileage on Ori's car = 73,033 miles.

identical digits = 40

The fewest number of miles that Ori needs to drive before the mileage shows three identical digits again is 40.

Answer: 31.4 feet

Step-by-step explanation:

For this, you basically need to calculate the perimeter of the circle. You do this using this formula:

diameter of the circle times Pie = the circumference of the circle

Since The number of Pie is infinite use the rounded version of pie to 2 decimal points which is 3.14(This is why the question asks for an approximate)

(Diameter = 10 Pie = 3.14 therefore circumference = 31.4)

10 times 3.14 = 31.4 feet

The amount of edging trim needed to surround the garden by placing the trim all along the gardens circumference is 31.4 ft.

The garden is circular in shape. Thereforem the trim that is needed to surround the garden is the circumfernce of the graden.

The circumference of a circle is the perimeter of the circle. Therefore,

circumference = 2πr

where

Therefore, the amount of edging trim needed to surround the garden by placing the trim all along the gardens circumference is as follows:

circumference = 2 × 3.14 × 5

circumference = 10 × 3.14

circumference = 31.4 ft
