Which equation represents the relationship between the angles shown below?
Answer:
4x + 44 = 180
Step-by-step explanation:
4x = 180- 44
4x = 136
x= 136÷ 4
x= 34
Answer:
4x + 44 = 180
Step-by-step explanation:
sum of angles on a straight line = 180
4x + 44 = 180
subtract 44 from both sides
4x + 44 - 44 = 180 - 44
4x = 136
Divide both sides by the coeficient of x
4x = 136
4 4
x = 34

if Penelope's car has an average fuel consumption of 3 miles per gallon and she uses 9.5 gallons how far did she drive
Answer:
approximately 3.16 repeated
Step-by-step explanation:
Given parameters:
Average fuel consumption of Penelope's car = 3miles per gallon
Amount of fuel used = 9.5 gallons
Unknown:
Distance of her drive = ?
Solution:
Since her rate of fuel consumption per miles is known, we can simply solve for the distance she covers.
Distance covered = Rate of fuel consumption per miles x amount of fuel used
Distance covered = 3 x 9.5 = 28.5miles
The distance covered by Penelope's car is 28.5miles
What is 94.239 rounded to the nearest thousandth?
94.239 is already rounded to the nearest thousand as the no. of digits after the decimal place is three.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, 94.239 rounded to the nearest thousandth it is already rounded to the nearest thousand the no. of digits after the decimal place is three.

Find the L.C.M of the given pair of numbers using the prime factors method. 70 and 84
Answer:
420
Step-by-step explanation:
Prime Number: a whole number greater than 1 that cannot be made by multiplying other whole numbers
First prime numbers: 2, 3, 5, 7, 11, 13, 17, ...
Prime Factorization: prime numbers that multiply together to make the original number.
LCM = least common multiple: smallest positive number that is a multiple of two or more numbers
Start by finding the prime factorization of each number.
Start with the smallest prime number: 2
70 ÷ 2 = 35
35 is not divisible by 2 or 3, but is divisible by 5:
35 ÷ 5 = 7
7 is a prime number, so cannot be divided any further
So 70 = 2 × 5 × 7
Start with the smallest prime number: 2
84 ÷ 2 = 42
Again divide by 2:
42 ÷ 2 = 21
Now divide by 3:
21 ÷ 3 = 7
So 84 = 2 × 2 × 3 × 7
Write each number as a product of primes, matching primes vertically when possible
84 = 2 × 2 × 3 × 7
70 = 2 × 5 × 7
Now bring down the primes in each column. The LCM is the product of these factors.
LCM = 2 × 2 × 3 × 5 × 7 = 420
A triangle has sides with lengths of 60 feet, 63 feet, and 87 feet. Is it a right triangle?
Answer:
Yes
Step-by-step explanation:
We can use the Pythagorean Theorem to check if this triangle is a right triangle:
[tex]a^2+b^2=c^2[/tex]
Note that [tex]a[/tex] and [tex]b[/tex] are the legs of the triangle and [tex]c[/tex] is the hypotenuse:
Substitute the lengths of the sides into the equation:
[tex]60^2+63^2=87^2[/tex]
[tex]3600+3969=7569\\7569=7569[/tex]
Therefore this triangle is a right triangle.

Answer:
First option [tex]0, \frac\pi2, \pi, \frac{3\pi}2[/tex]
Step-by-step explanation:
first of all, let's replace the lhs with the equivalent in sine (from the pythagoran identiy on sine and cosine)
[tex]1-sin^2\theta =1-sin\theta[/tex]
At this point we take 1 from both side, and change signs just out of convenience.
[tex]\sin^2\theta =sin\theta[/tex]
Now we have 2 options. If [tex]sin \theta =0 \leftrightarrow \theta = k\pi[/tex] the equation is verified, and we got two solutions [tex]\theta =0; \theta = \pi[/tex]. Else, we can divide by [tex]sin\theta[/tex] and we get
[tex]sin\theta = 1 \leftrightarrow \theta = \frac\pi2+k\pi[/tex].
We can add everything together and write
[tex]\theta = k\frac\pi2; k\in\{0,1,2,3\}[/tex] or, in our case, the first answer.

( THE SUM OF THE MEASURES OF THE ANGLES BELOW IS 180* ) I will give brainlst for whoever gets this right and fills it out
Answer:
2x-10+x+x+10=180, or 4x=180
Step-by-step explanation:
So since the total is 180, you add them all up like an equation.
So,
2x-10+x+x+10
Combine like terms
4x=180
x=45
Then plug it back in to the equations.
x=45
(2x-10)=80
(x+10)=55

How many years is 10000 hours? [365 days = 1.0 year] *
There is 24 hours in a day. Therefore, there are 8760 hours in a 365-day calendar year (365 x 24 = 8760).
How many years is 10000 hours?
Take the total number of hours and divide it by the number of hours in a year.
10000/8760 = 1.1415
Therefore, 10000 hours is approximately 1.14 of a year.
