What is the solution of -4(-3m - 2) = 32?
Answer:
m=2
Step-by-step explanation:
Answer:
m=2
Step-by-step explanation:
First, write the equation and distribute.
-4(-3m-2)=32
12m+8=32
Now, subtract both sides by 8.
12m+8=32
-8 -8
12m=24
Divide both sides by 12.
12m=24
/12 /12
m=2
I hope this helps!! Have an amazing rest of your day!!! :3
At a large university, the probability that a student takes calculus and statistics in the same semester is 0.02. The probability that a student takes statistics is 0.18, while the probability of taking calculus is 0.10. Find the probability that a student is taking calculus given that he or she is taking statistics.
Answer:
The probability that a student is taking calculus given that he or she is taking statistics is = 0.26
Step-by-step explanation:
the probability that a student is taking calculus given that he or she is taking statistics.
Let C = Calculus
S = Statistics
We solve this above Question nursing the formula;
P ( C ∪ S) = P(C) + P ( S ) - P ( C ∩ S)
From the question,
P(C) = 0.10
P( S ) = 0.18
P ( C ∩ S) = 0.02
P ( C ∪ S) = ???
P ( C ∪ S) = 0.10 + 0.18 - 0.02
= 0.28 - 0.02
= 0.26
give three examples of equations where there be infinitely many solutions. PLEASE HELP I WILL GIVE U BRAINLENEST AND 75 POINTS!!!!!!!!!!
Answer:
2(5x+9) = 10x+18
3(4x+2) = 12x+6
5(3x+7) = 15x+35
Does this anwser your question?!?
Answer:
See below
Step-by-step explanation:
For there to be infinitely many solutions, the equations have to be the same on the left side of the equation as on the right
3x+6 = 3 ( x+2)
As you can see when we distribute
3x+6 = 3x+6
Another example
2x+3 = x+ x+ 1+2
When we combine like terms
2x+3 = 2x+3
A third example
2x -5 +2x -6 = 7x-3x - 15+4
Combine like terms
4x -11 = 4x -11

Satellites in low-Earth orbit circle around our planet at about 4.72 miles per second. A satellite that relayed a phone text message traveled 16.52 miles before the message reached the recipient. How long did it take the text to go from phone to phone? It took the text seconds to go from phone to phone.
Answer: 3.5
Step-by-step explanation:
Divide 16.52 by 4.72. It equals 3.5.
Using the speed - distance relationship, the time it'll take for the text to travel from phone to phone is 3.5 seconds.
Given the parameters :
Transmission speed = 4.72 miles per second Distance traveled = 16.52 milesRecall :
Time = Distance ÷ SpeedTime taken = (16.52 / 4.72) = 3.5 seconds.
The time it took the text to travel from phone to phone is 3.50 seconds.

Where do the points of concurrency of certain types of triangles lie?
The circumcenter of an obtuse triangle lies the triangle.
The incenter of a right triangle lies the triangle.
The point of concurrency of the angle bisectors of an acute triangle lies the triangle.
The point of concurrency that is equidistant from the vertices of a right triangle lies the triangle.
Answer:

The points of concurrency of a triangle include the following:
The circumcenter of an obtuse triangle lies outside the triangle.The incenter of a right triangle lies inside the triangle.The point of concurrency of the angle bisectors of an acute triangle lies inside the triangle.The point of concurrency that is equidistant from the vertices of a right triangle lies on the triangle.What is a triangle?A triangle can be defined as a two-dimensional shape that is typically made up of three (3) sides, three (3) vertices and three (3) angles. This ultimately implies that, a polygon that has three (3) lengths of sides is a triangle.
Types of triangleIn Geometry, there are different types of triangle based on the length of their sides, vertices and angle, these include;
Equilateral triangleScalene triangleIsosceles triangleObtuse triangleRight triangleWhat is a point of concurrency?A point of concurrency refers to a single point that is shared by three (3) or more lines, segments, rays, or planes. Thus, a triangle is considered to be concurrent when three (3) or more lines intersect at a single point.

Answer:
Measure 1 is 112º
You know that 112º is the closest answer because you can see the angle is obtuse. And obtuse is an angle less than 180 but more than 90º
Step-by-step explanation:
So a straight line is equal to 180º so just set the equations equal to 180. Your final equation should look like (3x + 22) + (2x + 8) = 180
Now all you have to do is solve for x.
3x + 22 + 2x + 8 = 180
Combine like factors
3x + 2x = 5x
22 + 8 = 30
Now your equation should look like 5x + 30 = 180
Subtract 30 from both sides. -30 -30
----------
150
So now the equation should look like 5x = 150
Divide both sides by 5, 150/5 = 30
SO x = 30
Plug 30 in to the equation to check your answer
(3*30 + 22) = 112
(2*30 + 8) = 68
112 + 68 = 180

Marc mixes blue and yellow paint to make his favorite shade of green, which he'll use to paint his house. He has 14 cans of blue paint and 20 cans of yellow paint when he starts. He wants the same green color every time he mixes, so the amounts of blue and yellow must always be proportional to the original mixture. On day 1, he mixes 4 cans of blue and 6 cans of yellow. On day 2, he mixes 6 cans of blue and 9 cans of yellow. 1. In simplest form, what is the ratio of blue paint to yellow paint in the mixture? Type your answer in the space below.
Answer:
The answer is 0,66
Step-by-step explanation:
Assuming he gets the exact same shade of green everyday, the ratio of blue to yellow for Marc's green color is 0,66 because 4 / 6 and 6 / 9 give the same results when calculated in decimal.

The short arrow shows the hours so we move that four numbers clockwise (to the right). The long arrow shows minutes so we move it two numbers clockwise since inbetween each number is 5 minutes and we need to go 10 minutes. We switch the am to pm since the shorter arrow moves past the 12.
