Find the area of the triangle

Mathematics
2 answers:
dusya [7]3 years ago

Hello!

To find the area of a triangle, first multiply the base by the height. Afterwards, divide the product by 2.

Base: The bottom side of the triangle.
Height: The distance from the bottom to the top of the triangle.

Base = 13
Height = 18.2

13 × 18.2 = 236.6

Now we do the final step, which is to divide by 2.

236.6 ÷ 2 = 118.3

118.3 is your answer.

But why do we divide the product of the base and the height by 2? This is because a triangle is recognized as half of a rectangle/square.

I think it should be 118.3 the equation is base times height divided by two equals the area

The sum of 2 numbers is 25. Their difference is 7. Find the numbers. Let x=1st number and y=2nd number
Alex Ar [27]

Answer:

x= 16 and y = 9

Step-by-step explanation:

1 st equation ; x+y = 25

2 nd equation ; x- y = 7

from 1 st equation

x = 25 - y

now putting value of x in 2 nd equation

x- y = 7

25 - y-y = 7

25 -2y =7

25-7 = 2y

18 = 2y

18/2 = y

y = 9

again

putting value of y in 1 st equation

x = 25-y

x = 25-9

x= 16

adelina 88 [10]

8 employees exercise at least three times a week

<em><u>Solution:</u></em>

At the office where Mika works 41% of the 19 employees exercise at least three times a week

To find: Number of people who exercise at least three times a week

From given information,

Total employees = 19

Employees exercise at least three times a week = 41 % of total employees

Therefore, we have to evaluate 41 % of 19

Number of people exercise at least three times week = 41 % of 19

\rightarrow 41 \% \text{ of } 19 = 41 \% \times 19\\\\\rightarrow 41 \% \times 19 = \frac{41}{100} \times 19 = 0.41 \times 19\\\\\rightarrow 41 \% \times 19 = 0.41 \times 19 = 7.79 \approx 8

Thus approximately 8 employees exercise at least three times a week

You are shopping for carpet for your living room which measures 19 feet by 12 feet. Charlie's Carpets sells carpet for $18 per s
Kamila [148]
----------------------------
Charlie's Carpets:
----------------------------
Carpet : $18/yd
Installation: $2/yd

Discount: 20% x $18 = 0.2 x 18 = $3.60
Carpet Price after discount = $18 - $3.60 = $14.40/yd²

Carpet Price with installation $14.40 + $2 = $16.40/yd²

----------------------------
Cindy's Carpet
----------------------------

Carpet = $18/yd²

Discount = 10% = 0.1 x $18 = $1.80
Price after Discount = $18 - $1.80 = $16.20/yd²

----------------------------
Summary:
----------------------------
Charlie's Carpet = $16.40/yd²
Cindy's Carpet = $16.20/yd²

CIndy's Carpet is cheaper.

----------------------------
Find Cost:
----------------------------
Length = 19 x 1/3 = 19/3 yards
Width = 12 x 1/3 = 4 yards

19/3 x 4 = 25 1/3 yd²

Cost = 25 1/3 x $16.20 = $410.40

------------------------------------------------------------------------------------
Answer: Cindy's Carpet is cheaper and it will cost $410.40.

Which of the following are important properties of the arithmetic mean? Check all that apply. Multiple select question. The mean
vovikov84 [41]

Answer:

All of the values in the data are used in calculating the mean.

The sum of the deviations is zero.

There is only one mean for a set of data.

Step-by-step explanation:

Required

True statement about arithmetic mean

(a) False

The mean can be equal to, greater than or less than the median

(b) True

The arithmetic mean is the summation of all data divided by the number of data; hence, all values are included.

(c) True

All mean literally represent the distance of each value from the average; so,  when each value used in calculating the mean is subtracted from the calculated mean, then the end result is 0. i.e.\sum(x - \bar x) = 0

(d) True

The mean value of a distribution is always 1 value. When more values are added to the existing values or some values are removed from the existing values, the mean value will change.

(e) False

Nominal data are not numerical or quantitative data; hence, the mean cannot be calculated.
