Answer and Step-by-step explanation:
Distance is the numerical measurement to find the space or interval between two objects. Distance also refers to physical length. Point x to point y distance is denoted as |xy|
There are many ways to find out the distance, distance between two objects or two points. The efficient way of finding the distance between two points is given below. Mathematically, the distance between two points on a coordinate plane can be determined by using the distance formula, which is:
d =√((x2-x1)2+(y2-y1)2),
Where (x1, y1) and (x2, y2) coordinates, and d is the distance.
The middle point between these two points is known as midpoint and can find out by using the formula
Midpoint = a + b /2.
The distance between two points number line can also be calculated by using the formula:
AB =|b –a| or |a-b|.
h(x) = 10x - x2 + 4
h(2) =
Answer:
h(2) = 20
Step-by-step explanation:
h(x) = 10x - x^2 + 4
Let x = 2
h(2) = 10*2 - 2^2 + 4
=20 -4+4
=20

Which College entrance exam has the least amount of math problems to work?
Answer:
SAT
Step-by-step explanation:
The two main college entrance exams are the SAT and ACT which are used for almost all colleges in the United States. Between these two the SAT has a lesser focus on math in general. Instead, the SAT tends to focus more on word problems and the process taken to solve them. This does not mean that it has no math at all, there is still a math section on the SAT's but it is not as extensive as in the ACT's.

Step-by-step explanation:
simple, divide 24/3 and you get your answer.
why?
because when you divide 3(game) by 24(score) you get how much score you get per 1 game.
same if you divide for 32/4 and 5/40, you get the same answer.
Seven students have been entered into the prize drawing for perfect attendance. The first name drawn recieves a $50 giftcard. The second name drawn recieves a $25 giftcard. The third name drawn recieves a $10 giftcard. How many ways can these rewards be given out? * bila.
Answer:
21
Step-by-step explanation:
there are 7 students and 3 prizes so all you needed to do was multiply 3 by 7 or 7 by 3.
Answer:
35 different ways!
Step-by-step explanation:
7! / 3! * (4!)
If you know combinations and permutations, then the above formula will make sense.
Since this question is asking for all possible combinations, it's this formula if you don't know it:
n! / r! (n - r)!
n is the total number of things, which in this case are people. So, we get 7 and r is the set amount of the things used at a time which is 3... because out of 7 people only 3 can win gift cards.
Hope this helps!

Which is the solution to this equation 8x -5(x-3) = 18
Answer:
Step-by-step explanation:
Distribute the -5 to the parenthesis to get:
[tex]8x-5x+15=18\\8x-5x=3\\3x=3\\x=1[/tex]
Answer:
x = 1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8x−5(x−3)=18
(Distribute)
8x+−5x+15=18
(Combine Like Terms)
3x+15=18
3x+15=18
Step 2: Subtract 15 from both sides.
3x+15 −15 = 18 −15
3x=3
Step 3: Divide both sides by 3.
3x/3= 3/3
x = 1
20.0% Complete You work on a manufacturing line. Currently, the status board for the line says"-55" This means that your line still needs to produce 55 items to meet the day's goal. Q. If your line produces 30 items in the next hour, what number will be displayed on the status board? A. 25 B. 85 C. -25 D. -85
Answer:
C. -25
Step-by-step explanation:
Since the current number is -55, it depicts the number to achieve the target.
That is the current position states that we require 55 more units to produce.
If we produce 30 more units in an hour, we shall require 55 - 30 = 25 more units to produce, in order to achieve target.
Since target is decreased by 30, but yet not achieved completely it will still be a negative number.
Thus, the correct answer is
C. -25
This depicts that achieved volume of units is short by 25 units in order to achieve the target.

Ariah has $141.25 in her savings account. She deposits $15 every week. Her mother also deposits $25 into the account every time Ariah does cares for her younger sibling for the day. Her savings account balance can be shown with the following expression: 25c + 15w + 141.25 If Ariah saves for 8 weeks and cares for her younger siblings 16 times, how much will she have in her account?
Answer:
$661.25Step-by-step explanation:
Expression
25c + 15w + 141.25And
w = 8 and c = 16The amount is
25*16 + 15*8 + 141.25 = $661.25Answer:
$661.25
Step-by-step explanation:
25(16) + 15(8) + 141.25
400 + 120 + 141.25
520 + 141.25
661.25

Hi there! :)
a) (ii) The two angles are vertical angles, so they are congruent.
b)(i) y = 71°
(ii) The two angles are alternate interior angles, so they are congruent.
c) z = 44°
(ii) m∠x = 65° because the two angles are vertical angles, so they are congruent.
b) (i)
∠y is an alternate interior angle, therefore:
m∠y = 71°
c) Use the sum of interior angles of a triangle to determine the measure of angle z:
180 = 65 + 71 + z
180 = 136 + z
180 - 136 = z
z = 44°.
are these rational or irrational. a. 0 b. -3/4 c. 3pi

Find an equation parallel to y=-5 and passing through (-2, -9)
What is the equation (answer in standard form)
Answer:
[tex]y=-9[/tex]
Step-by-step explanation:
We want to find an equation of a line that is parallel to y=-5 and also passes through (-2,-9)
Note that y=-5 is a horizontal line.
This means that in order to be parallel to our old line, our new line must also be horizontal.
So, the equation of our new line will be whatever y-coordinate is being used from our point.
Our point is (-2,-9).
The y-coordinate is -9.
So, the equation of our horizontal line is:
[tex]y=-9[/tex]
This is in standard form.
And we're done!

Answer:
x=1±i√5
Step-by-step explanation:
the quadratic equation is in the form :
y=ax²+bx+c
y= 2x²-4x+12
x=(-b±√b²-4ac)/2a
x=-(-4)±√-4²-4(2)(12)/2a
x=4±√16-96/4
x=4±√-80/4
since the number under the square root then √-80=4i√5 ( assuming possitive numbers)
x=(4±4i√5)/4
x=4(1±i√5)/4
x=1±i√5

8b-7 = 7b - 2
-12+5k=15-4k
Answer:
Step-by-step explanation:
8b - 7 = 7b - 2
Bringing like terms on one side
8b - 7b = - 2 + 7
B = 5
-12 + 5k = 15 - 4k
Bringing like terms on one side
5k + 4k = 15 + 12
9k = 27
k = 27/9 = 3
