Answer.
Step-by-step explanation:
Given = sum of two exterior angle of a triangle is 272 .
rule of triangle is that each and every angle which are outside a triangle is 360.
so, 272 + x = 360
x = 360 - 272
x = 88
A race car can travel at a speed of 3.4 x 10^2 miles/hour. The Speed of Sound is approximately 7.6 × 10^2 miles/hour. How many times faster is the Speed of Sound than the Bullet Train?
Answer:
The speed of sound is 2.23 times of the speed of race car
Step-by-step explanation:
Given that,
The speed of a race car = [tex]3.4\times 10^2\ mi/h[/tex]
The speed of sound = [tex]7.6\times 10^2\ mi/h[/tex]
Dividing the speed of sound to the speed of a race car. So,[tex]\dfrac{\text{speed of sound}}{\text{speed of race car}}=\dfrac{7.6\times 10^2}{3.4\times 10^2}\\\\\dfrac{\text{speed of sound}}{\text{speed of race car}}=2.23[/tex]
So, the speed of sound is 2.23 times of the speed of race car.
Simplify: 10(48 1/4)-3(3 1/4)
Answer:
472.75 or 472 3/4
Step-by-step explanation:
10(48 1/4)-3(3 1/4) =
10(48.25) - 3(3.25) =
482.5 - 9.75 =
472.75
In fraction form, this is 472 3/4
Please help! (Geometry)
Answer:
x=5
From the dashed lines on the two sides of this triangle, we can see that these two sides are congruent, or equal, to each other.
In geometry, if a triangle has two congruent sides, then we can call it a isosceles triangle.
In an isosceles triangle, the corners opposite the congruent sides are also congruent, meaning, that the angle measures of this triangle are: 88, 9x+1, and 9x+1.
We also know that angles in a triangle add up to 180 degrees.
So, we have: 88+(9x+1)+(9x+1) = 180
Simplifying: 18x + 2 = 92
Solving: 18x = 90, so x=5

Two numbers have a difference of 13. The sum of twice one number and 3 times the other number is 1. Write a system of equations and solve the system to find the two numbers. You need not show 7 steps for this problem. Just show the system, solve the system, and write the two numbers.
Answer:
first number = 8
second number = -5
Step-by-step explanation:
Let
x = first number
y = second number
Two numbers have a difference of 13.
x - y = 13
The sum of twice one number and 3 times the other number is 1
2x + 3y = 1
x - y = 13 (1)
2x + 3y = 1. (2)
From (1)
x = 13 + y
Substitute into (2)
2x + 3y = 1.
2(13 + y) + 3y = 1
26 + 2y + 3y = 1
26 + 5y = 1
5y = 1 - 26
5y = -25
y = -25/5
y = -5
Substitute y = -5 into (1)
x - y = 13
x - (-5) = 13
x + 5 = 13
x = 13 - 5
x = 8
The obtained number is 12. And the system of equations is 2c + 4p = 40
How to solve system of equations ?Although each chicken has two legs and each pig has four legs, the total number of animal legs is:
2c + 4p = 40
Once we simplify the above equation, we get
c + 2p = 20
We also know that there are 16 animal heads in total, which can be expressed as:
c + p = 16
We can solve for "c" that use these two equations.
Once we multiply the second equation by 2, we get:
2c + 2p = 32
Once we subtract this equation from that, we get:
2p = 8
Once we solve for "p," we get:
p = 4
Substituting this "p" value into the second equation yields:
c + 4 = 16
Once we solve for "c," we get:
c = 12
As an outcome, your parents hold 12 chickens.

Factorise
x^2+18x+80
Answer:
(x + 10)(x + 8)
Step-by-step explanation:
Given
x² + 18x + 80
Consider the factors of the constant term (+ 80) which sum to give the coefficient of the x- term (+ 18)
The factors are + 10 and + 8 , since
10 × 8 = + 80 and 10 + 8 = + 18 , then
x² + 18x + 80 = (x + 10)(x + 8) ← in factored form
