The legs of a right triangle are 3 and 6. Find the length of the hypotenuse
Answer:
6.71 unit
Step-by-step explanation:
Given that:
Legs of a right angle triangle are 3 and 6
From Pythagoras rule;
Hypotenus = sqrt(Adjacent² + opposite²)
Both legs are adjacent and opposite
Hence,
Hypotenus = sqrt(3² + 6²)
Hypotenus = sqrt(9 + 36)
Hypotenus = sqrt(45)
Hypotenus = 6.708
Hypotenus = 6.71

The perimeter of a triangle is 17 inches. One side is 5 inches, and another is 4 inches. What is the length of the third side?
Answer:
8inches
Step-by-step explanation:
Length of the third side = perimeter - ( side1 + side2 )
= 17 - (5+4)
= 17 - 9

The third side of the right triangle is 10.72 unit.
What is Pythagoras theorem?Pythagoras' Theorem states that the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides.
Given, the side of right triangle is;
Let H be hypotenuse = 14
And P be perpendicular = 9
Then to find third side base be B,
we use the Pythagoras theorem;
(H)² = (P)²+(B)²
Rearranging,
(B)² = (H)² - (P)²
(B)² = (14)² - (9)²
(B)² = 196 - 81
(B)² = 115
B = 10.72 unit.
Therefore, the third side is 10.72 unit.

ASAP!! Find the length of side x in simplest form with a rational denominator
Answer:
[tex]x=\sqrt{14}[/tex]
Step-by-step explanation:
This triangle is a 45-45-90 triangle.
By using the image I posted, we can find x easily.
So, we have [tex]\sqrt{7}[/tex] as one of the sides.
They hypotenuse, which is x is just [tex]\sqrt{7} \sqrt{2}[/tex]

3/4(1/6x+16)=3/7(4 3/8x-21) I WILL AWORD BRILLENEST :>
Answer:
x=12
Step-by-step explanation:
Let's solve your equation step-by-step.
34(16x+16)=37((438)(x)−21)
Step 1: Simplify both sides of the equation.
18x+12=158x−9
Step 2: Subtract 15/8x from both sides.
18x+12−158x=158x−9−158x
−74x+12=−9
Step 3: Subtract 12 from both sides.
−74x+12−12=−9−12
−74x=−21
Step 4: Multiply both sides by 4/(-7).
(4−7)*(−74x)=(4−7)*(−21)
x=12
Answer:
x=12
Answer:
x = 12
Step-by-step explanation:
34(16x + 16) = 37((438)(x) − 21)
18x + 12 = 158x − 9
18x + 12 − 158x = 158x − 9 − 158x
−74x + 12 = −9
−74x + 12 −12 = −9 −12
−74x = −21
(4−7) × (−74x) = (4−7) × (−21)
x = 12
What is the difference between 4/5- 1/2 *
Answer:
0.3
Step-by-step explanation:
Answer:
3/10
Step-by-step explanation:
1. find the lowest common denominator which is 10.
2. for 4/5 you have to multiply 5 by 2 in order to get 10, so you multiply the numerator by 2 as well which gives you 8/10.
3. for 1/2 you have to multiply 2 by 5 in order to get 10, so you multiply the numerator by 5 also which gives you 5/10
4. you work out the difference between both numerators which is 3 and keep the denominator the same

Find equivalent fractions and rewrite the problem and solve
Answer:
1001/1500
Step-by-step explanation:
The easiest method for doing this is to just average the two numbers.
e.g. to find a number x between the two numbers ab and cd
x=12[ab+cd]
=12[adbd+bcbd]
=ad+bc2bd
In this case…
x=(2×5)+(3×4)2×2×5=10+1230=2230=1115
You can easily see where that came from.
23=1015 and 45=1215
and the ‘common denominator’ means you just have to pick a value between 10 and 12 . i.e. 11
But you can also say…
23=100150 and 45=120150
and choose any of 101150,102150,...,119150
or
23=10001500 and 45=12001500
and choose any of 10011500,10021500,...,11991500
Answer:4/5 and 2/3 each have a common bottom of 15 so 4/5 is
12/15 and 2/3 will be 10/15
Step-by-step explanation:So than 12/15 forget the bottom don't subtract the bottom just look at it like [12-10] then you got 2 then you go back to the bottom and put it together so your answer is [2/15]

Cab A charges $20 at the start and $5 every mile after . Cab B charges $30 no matter how far you go. What are their initial values and their rates of change? When will their fares be equal?
Answer:
Car A: Initial Charge = 20
Car B: Initial Charge = 30
Car A: Rate = 5
Car B: Rate = 0
At 2 miles, their charges will be the same
Step-by-step explanation:
Given
Car A
[tex]Base\ Charge = \$20[/tex]
[tex]Rate = \$5[/tex] per mile
Car B
[tex]Base\ Charge = \$30[/tex]
Solving (a): The initial charge
First, we get the linear equation that represents both car's charges.
Represent number of miles with m.
So, the charges is:
Car A
[tex]A = Base\ Charge + Rate * m[/tex]
[tex]A = 20 + 5 * m[/tex]
[tex]A = 20 + 5m[/tex]
Set m to 0 to get the initial charge:
[tex]A = 20 + 5*0[/tex]
[tex]A=20[/tex]
and
[tex]Rate = 5[/tex]
Car B:
[tex]B = Base\ Charge + 0 * m[/tex] i.e. Rate is 0
[tex]B = 30+ 0 * m[/tex]
[tex]B = 30[/tex]
So:
[tex]Initial = 30[/tex] and [tex]Rate = 0[/tex]
Solving (b): When their charge wil be equal.
To do this, we set:
[tex]A = B[/tex]
[tex]20 + 5m = 30[/tex]
[tex]5m = 30- 20[/tex]
[tex]5m = 10[/tex]
[tex]m = 2[/tex]
At 2 miles, their charges will be equal

Since you know that your friend likes
green marbles better than red ones, the
bag has twice as many green marbles as
red.
The label on the bag says it contains a
total of 84 marbles.
How many green marbles are in the bag?
Number of green marbles in the bag is equals to [tex]56.[/tex]
What is number?
" Number is defined as the count of any given quantity as per condition."
According to the question,
Given,
Total number of marbles [tex]= 84[/tex]
[tex]'x'[/tex] represents the number of red marbles
As per given condition,
[tex]'2x'[/tex] represents the number of green marbles
Required equation we have,
[tex]x + 2x = 84\\\\\implies 3x =84\\\\\implies x = \frac{84}{3} \\\\\implies x = 28[/tex]
Substitute the value of [tex]'x'[/tex] to get number of green marbles ,
Number of green marbles [tex]2x = 2\times 28[/tex]
[tex]= 56[/tex]
Hence, number of green marbles in the bag is equals to [tex]56.[/tex]

Determine the percentage of those who uses the bus for 27 to 30 mins
The box plot is not given. So, I will make assumptions in order to solve this question.
Assume the following readings from the box plot:
[tex]Total\ Buses= 60[/tex]
[tex]27-30\ Minutes = 20\ buses[/tex]
Using these assumptions, the required percentage is:
Total = 6
27 to 30 minutes = 2
[tex]Percent = \frac{27\ to\ 30\ mins}{Total} * 100\%[/tex]
[tex]Percent = \frac{20}{60} * 100\%[/tex]
