Lowest common multiple of 6 , 7 and 8
Answer:
The LCM is 168
Step-by-step explanation:
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.
Answer:
Lowest common multiple is 168
If angle PQT = (3x + 47)* and angle PQR = (6x - 25)', find the measure of angle SQR.
Since , angle PQT and PQR are in a line .
So , PQT=PQR
(3x + 47) + (6x - 25) = 180
x = 17.56
Now , PQR and SQR are also in same line .
So , PQR + SQR = 180
( 6x - 25 ) + SQR = 180
105.33 - 25 + SQR = 180
SQR = 99.67°
Hence , this is the required solution .
A car is traveling at a rate of 93 miles per hour. What is the car's rate in miles per minute? How many miles will the car travel in 15 minutes? Do not round y
answers.
Answer: The car is going 1.55 miles per minute.
Step-by-step explanation: Since there are 60 minutes in an hour, and the car is going 93 mph, you would simply divide 93 by 60.
The car's rate in miles per minute is 1.55 miles.
The car will travel 23.25 miles in 15 minutes.
What is Speed- Distance Formula?Speed = Distance/Time Distance = Speed X TimeTime = Distance / SpeedGiven:
A car is traveling at a rate of 93 miles per hour.
In 60 minutes the car travel = 93 miles
So, In one minutes the car travels = 93 /60
= 1.55 miles
and, In 15 minutes the car travel = 1.55 x 15
= 23.25miles

The actual distance between the library and train station is 500 ft. Explain how you
could find the distance between them in centimeters on the map.
Answer:
15,420 cm
Step-by-step explanation:
Given the actual distance between the library and train station to be 500 ft, to find the distance between them in centimeters, we ill convert 500 ft to cm as shown;
Given the conversion:
1 ft = 30.48cm
500ft = x cm
Cross multiply
x cm * 1ft= 30.48 cm * 500ft
x cm = 30.48 cm * 500ft/1ft
x cm = 15,240 cm
Hence the distance between them in centimeters on the map is 15,420 cm

what are the steps to simplifying radical expressions?
Answer:
Step 1: Find the prime factorization of the number inside the radical.
Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.
Step 4: Simplify the expressions both inside and outside the radical by multiplying.

Prove that if 5(m - 1) = -25, then m = -4.
Answer:
The equation is true
Step-by-step explanation:
First, input -4 instead of m in the equation:
5(-4 - 1) = -25
Then, distribute:
-20 - 5 = -25
Finally, simplify:
-25 = -25
This equation is true, and that's how you prove it.
Hope this helps!
Answer:
M= -4
Step-by-step explanation:
1. Distribute the 5 into the parentheses
5m-5=-25
2. Now add 5 on both sides
5m=-20
3. Now divide 5 by -20

For the given octagon, if its diagonals are made then it will be divided into 8 triangles, such that each triangle will be equal to the other.
Now, if the area of a single triangle is calculated then the area of the triangle will be,
Area of triangle = (1/2) × b × h
Further, since there are 8 triangles, therefore, the area of the octagon can be written as,
Area of octagon = Area of triangle × 8
= (1/2) × b × h × 8
= 4bh
Hence, the area of the octagon is 4bh.
B.)
The formula can be solved for h as shown below,
Area of octagon = 4bh
A = 4bh
Divide both the sides by 4b, therefore, we can write,
A/4b = 4bh/4h
h = A/4b
Hence, the formula when solved for h will be equal to A/4b.

Answer:
178.67
Step-by-step explanation:
One third written as a fraction is 1/3. You can also write it as a decimal by simply dividing 1 by 3 which is 0.33.
If you multiply 0.33 with 536 you will see that you will end up with the same answer as above.
You may also find it useful to know that if you multiply 0.33 with 100 you get 33.33. Which means that our answer of 178.67 is 33.33 percent of 536.

Answer:
If the circle is inside the square the area of the square is 144

The diameter of a circle is equal to the side length of a square.
So [tex]d = 2r[/tex] the diameter of the circle is 2(6)=12
so one side length of the equals 12
Area of square = [tex]s^{2}[/tex] [tex]12^{2} = 144[/tex]
find the zero of the function h(x) = 4x+2
Answer:
[tex]x=-1/2=-0.5[/tex]
Step-by-step explanation:
So we have the function:
[tex]h(x)=4x+2[/tex]
To find the zero(s) of a function, set the function equal to 0 and solve for x. So:
[tex]0=4x+2[/tex]
Subtract 2 from both sides:
[tex]-2=4x[/tex]
Divide both sides by 4:
[tex]x=-1/2=-0.5[/tex]
So, the zero of the function is -0.5.
This means that the graph (a line) crosses the x-axis at (-0.5, 0).
