Answer:
[tex]\sqrt{21}[/tex]
Step-by-step explanation:
Use the pythagorean theoreom, a^2+b^2=c^2.
We know the hypontenuse and one of the sdes
a^2+2^2=5^2
a^2+4=25
subract four from both sides to isolate variable
a^2=21
square root both sides and you have the answer of sq root 21!

Find all real square roots of -36
Answer:
The answer is ±6.
Step-by-step explanation:
The positive and negative square roots of 36 are 6. and −6. Both 6, and −6 are square roots of 36 since they both give 36 when squared:...
6^2=6×6=36
(−6)2=(−6)×(−6)=36
All positive real numbers have a positive and negative real square root which are additive inverses of one another.
The principal square root is the positive one and is the one meant when we use the √... symbol. So:...
√36=6
If we want to refer to the negative square root, then just put a minus sign in front:...
−√36=−6
The two square roots of -36 are 6i and -6i, where i is the imaginary unit.
What is Number system?A number system is defined as a system of writing to express numbers.
Since the square of any real number is always non-negative, there is no real number whose square is equal to a negative number.
Therefore, the expression √(-36) has no real square roots.
However, we can express the square root of -36 using imaginary numbers.
By definition, the imaginary unit "i" is equal to the square root of -1. Using this definition, we can rewrite √(-36) as:
√(-36) = √(36) × √(-1) = 6i
Therefore, the two square roots of -36 are 6i and -6i, where i is the imaginary unit.

Bobby decides to sell lemonade on a hot summer day. If Bobby sells 20 glasses of lemonade for $2.00 per cup, and his average total cost is $1.70, what are Bobby's economic profits for the day?
Bobby's economic profit for the day is $6.
Bobby's economic profit is total revenue less total cost.
Economic profit = total revenue - total cost
Total revenue = price x glasses of lemonade sold
20 x $2 = $40
Total cost = average total cost x glasses of lemonade sold
$1.70 x 20 = $34
Economic profit = $40 - $34 = $6.

Approximately__ tons of LNG will be produced in may, and approximately 104,489 tons will be produced in___
Help plz :,)
Answer:
Step-by-step explanation:
For all Plato users
Approximately 94437.825 tons of LNG will be produced in May, and approximately 104,489 tons will be produced in October month.
Given that, the production of LNG by an energy company increases by 1.7% each month.
How to find the percentage of the number?Convert the problem to an equation using the percentage formula: P% * X = Y.
Production in April month=91,307+1.7% of 91,307
=91,307+1.7% ×91,307
=92,859.219 tons
Production in May month=92,859.219×(1+1.7%)
=94437.825 tons
Production in June month=94437.825×(1+1.7%)=96,043 tons
Production in July month=96,043×(1+1.7%)=97,676 tons
Production in August month=97,676×(1+1.7%)=99,336.49 tons
Production in September month=99,336.49×(1+1.7%)=1,01,025.21 tons
Production in October month=1,01,025.21×(1+1.7%)=1,04,489 tons
94437.825 tons of LNG will be produced in May, and 104,489 tons will be produced in October month.

Sam scored 17 out of 20 in her test, her % score is...... what A 17% B 85% C 80% D 0.85%
Answer:
the answer is 85%
Step-by-step explanation:
To find the percentage you will divide:
17 divided by 20 = o.85
Answer:
B. 85%
Step-by-step explanation:
in order to find out her percentage, you want to do 17/20
the reason we do 17/20 and not 20/17 is because 20/17 gives you 1.1, which is both not an option and does not make logical sense
17/20 = 0.85
in order to make this a percentage, multiply 0.85 by 100
0.85 x 100 = 85
so your answer is 85%, or B

Answer:
Nominal data are used to label variables without any quantitative value. Common examples include male/female (albeit somewhat outdated), hair color, nationalities, names of people, and so on. In plain English: basically, they're labels (and nominal comes from "name" to help you remember). You have brown hair (or brown eyes).

The bus fare in a city is $2.00. People who use the bus have the option of purchasing a monthly coupon book for $28.00. With the coupon book, the fare is reduced to $1.00. Determine the number of times in a month the bus can be used so that the total monthly cost without the coupon book is the same as the total monthly cost with the coupon book
Answer:
56 = 56
Step-by-step explanation:
Given:
Bus fare = $2.00
coupon book = 28.00
bus fare w/ coupon book = $1.00
let x be the number of bus rides.
2.00x = 1.00x + 28.00
2.00x - 1.00x = 28.00
1x = 28.00
x = 28.00
24 bus rides for both to have the same cost.
2.00x = 1.00x + 28
2.00(28) = 1.00(28) + 28
56 = 28 + 28
56 = 56
