Two flag poles at Liberty Park are 27 feet tall. The distance from the top of one flag pole to the base of the other is 45 feet. What is the distance between the two flag poles?
Answer:
Step-by-step explanation:
Answer:
The distance between the two poles is 36 feet.
Step-by-step explanation:
If 2 flag poles are 27 feet tall each
if the distance from one flag pole to the base of the other flag pole is 45 feet, this forms the shape of a right angle triangle.
Here, we are going to make use of the Pythagoras theorem.
a2 + b2 = c2
27 2 + b2 = 45 2
b2 = 45 2 - 27 2
b = 45 2 - 27 2 (square root)
b = 2025 - 729
b= 1296 (square root)
b = 36

Written as a simplified polynomial in standard form, what is the result when
(x - 2)^2is subtracted from 9x^2-8x?
Answer:
9x^2 - 10x -4
Step-by-step explanation:
It is set up like this
9x^2 - 8x
- (x-2)2
First solve (x-2)2
the answer is (2x-4)
so now you can do this instead
9x^2 - 8x
- 2x - 4
----------------------------------
9x^2 - 10x +4
9x^2 minus zero is 9x^2
-8x-2x is -10x
0- -4 is 4 because that is like saying 0 + 4 because double negatives equal a positive
A simpler way is to change all the numbers to the opposite sign and then change the minus to a plus
like this
9x^2 - 8x
+ -2x + 4
----------------------------------
9x^2 - 10x +4

At the country fair, Maya observes that the wheel of chance has 25 numbered slots. If each play costs a quarter, how much will Maya likely have to spend before she gets her winning number?
Answer:
6 1/4
Step-by-step explanation:
Given
Total number of wheel chance = 25
Each play = 1 quarter
1 play = 1/4
To calculate the amount Maya has to spend to get her winning number, we will say;
25 plays = x
Divide both expressions
1/25 = 1/4÷x
1/25 = 1/4x
Cross multiply
4x = 25
x = 25/4
x = 6 1/4
This mean that Maya will have to spend 6 1/4 before she gets her winning number

Answer:
[tex]\sqrt{10}[/tex]
Step-by-step explanation:
This is a 45-45-90 triangle whose leg to hypotenuse ratio is 1 / [tex]\sqrt{2}[/tex]
so I set up a proportion of 1 / [tex]\sqrt{2}[/tex] = x / 2 [tex]\sqrt{5}[/tex]
cross-multiply to get [tex]\sqrt{2}[/tex]x = 2[tex]\sqrt{5}[/tex]
x = 2[tex]\sqrt{5}[/tex] / [tex]\sqrt{2}[/tex] and multiply numerator and denominator by [tex]\sqrt{2}[/tex], this is called rationalizing the denominator
lets do
[tex]\\ \sf\longmapsto \sqrt{2}x=2\sqrt{5}[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{2\sqrt{5}}{\sqrt{2}}[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{2}\sqrt{5}[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{2(5)}[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{10}[/tex]

what is half of 3/4 teaspoon?
Answer:
One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons. One method of finding the answer in the fraction form of 3/8 is to multiply the fraction 1/2 by 3/4 : )
Step-by-step explanation:
One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons.
Here, we have,
given that,
what is half of 3/4 teaspoon
One method of finding the answer in the fraction form of 3/8 is
to multiply the fraction 1/2 by 3/4 ,
or, we can divide 3/4 by 2
i.e. 1/2 × 3/4
as, half = 1/2
so, we get,
=> 3/ 2×4
=> 3/8
=>0.375
Hence, One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons.

Louis invested £2950 in a savings account for 5 years.
He was paid 1.9% per annum compound interest for each of the first 4 years.
He was then paid R% interest for the fifth year.
Louis had £3257 in his savings account at the end of the 5 years.
Work out the value of R.
Give your answer correct to 1 decimal place.
Answer:
2.4%
Step-by-step explanation:
The value of R is, 2.4%
What is Simple interest?A quick and easy method of calculating the interest charge on a loan is called a Simple interest.
Given that;
Louis invested £2950 in a savings account for 5 years.
He was paid 1.9% per annum compound interest for each of the first 4 years.
And, He was then paid R% interest for the fifth year.
Louis had £3257 in his savings account at the end of the 5 years.
Here, We know that;
⇒ Compound interest formula = Capital × (1 + r%) ⁿ
Where, n is time in years.
So, We can formulate;
⇒ £2950 × (1 + 0.019)⁴
⇒ £3180.67
And, For calculate R;
⇒ £3180.67 × (1 + R%)⁵ = £3257
⇒ R = 2.4%

PLS HELP- Richard and Teo have a combined age of 33. Richard is 15 years older than twice Teo's age. How old are Richard and Teo?
Answer:
Teo= 9
Richard= 24
Step-by-step explanation:
x= Richard
y= Teo
33-15= 18
18÷2= 9
15+9=24
Teo is 6 years old and Richard is 27 years old.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
Let x be Teo's age, then Richard's age is 15 years older than twice Teo's age, or 15 + 2x. The combined age of Richard and Teo is 33, so we can write an equation:
x + (15 + 2x) = 33
Simplifying and solving for x, we get:
3x + 15 = 33
3x = 18
x = 6
So Teo is 6 years old and Richard is 15 + 2(6) = 15 + 12 = 27 years old.
