Answer:
Substitution
Step-by-step explanation:
In your premises, the state AB = BC is given to be true. In math, substitution is taking one value in an equation and "subbing it out for" one that we know has the same value. This means anywhere we see AB, we can substitute BC and the equation will still be true, because AB = BC.
In the example given, that changes AB + BC = AC to AB + AB = AC.
We substituted the AB with BC, because we know that they are of the same value.

Answer:
(5, 2)
Step-by-step explanation:
understanding the questionThe question is asking you to express the temperature at 5 pm as a pair of graph coordinates.
Doing this requires that you ...
read from the graph the temperature at 2 pmread from the graph the temperature at 8 pmfigure the temperature halfway between those valuesexpress the 5 pm temperature as an ordered pair (hours, °C)__
reading the graphThe description of the graph tells you the horizontal scale is hours after noon, so the temperature at 2 pm will be a point on the graph with an x-coordinate of 2. That point is (2, 7), indicating the temperature at 2 pm is 7 °C.
Likewise, the temperature at 8 pm is shown as the point on the graph with x-coordinate 8. That point is (8, -3), indicating a temperature of -3°C at 8 pm.
halfway temperatureThe temperature halfway between those values (7 °C and -3 °C) can be found several ways. Perhaps the easiest is to average the values:
(7 +(-3))/2 = 4/2 = 2
The temperature at 5 pm is 2 °C.
coordinatesCoordinates on the graph are ordered pairs of the form (x, y) = (hours, °C). The time 5 pm is 5 hours after noon, so the x-coordinate is 5. The temperature at 5 pm is halfway between the temperatures at 2 and 8 pm, which we have computed to be 2 °C, so the y-coordinate is 2.
The coordinates that represent the temperature at 5 pm are ...

Answer:
sin(t) = 4*sqrt(5) / 21; cos(-t) = 19/21
Step-by-step explanation:
think of a right triangle with an adjacent leg a, opposite leg b, and hypotenuse c.
cos(t) = a/c = 19/21. so we can assume a=19 and c=21.
using Pythagorean's theorem, find b: b = sqrt(21^2 - 19^2) = 4*sqrt(5) or 8.944
since tan(t)> 0, b/a > 0 and a is positive so b must be positive. using this information, we know sin(t) = b/c = 8.944/21 or 4* sqrt(5) / 21
since cos x is an even function, cos(-x) = cos x so cos(-t) = cos(t) = 19/21

The expressions x - 2 and x + 3 represent the length and width of a rectangle, respectively. If the area of
the rectangle is 24, what is the perimeter of the rectangle?
O 20
022
O24
O28
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Let's get it solved ~
We have been given length and width of a rectangle in terms of x ~
that is :
length = x + 3width = x - 2Area of the rectangle is given ~ i.e 24 unit²
Area of rectangle in terms of x is :
[tex]\qquad \sf \dashrightarrow \:(x - 2) \sdot(x + 3) = 24[/tex]
[tex]\qquad \sf \dashrightarrow \: {x}^{2} + 3x - 2x - 6= 24[/tex]
[tex]\qquad \sf \dashrightarrow \: {x}^{2} +x - 6 - 24 = 0[/tex]
[tex]\qquad \sf \dashrightarrow \: {x}^{2} +x -30= 0[/tex]
[tex]\qquad \sf \dashrightarrow \: {x}^{2} + 6x - 5x - 30 = 0[/tex]
[tex]\qquad \sf \dashrightarrow \: {x}^{}( x + 6) - 5(x + 6)= 0[/tex]
[tex]f(x) = \begin{cases}x = - 6 \: \textsf{ \: if \:x + 6 = 0 } \\ \\ x = 5 \: \: \: \: \: \: \textsf{if \: x - 5 = 0} \end{cases}[/tex]
but since side of a rectangle can't be negative, we have to take value of x as 5
now, Perimeter of rectangle is ~
[tex]\qquad \sf \dashrightarrow \:2(width \: + \: length)[/tex]
[tex]\qquad \sf \dashrightarrow \:2(x - 2 + x + 3)[/tex]
[tex]\qquad \sf \dashrightarrow \:2(2x + 1)[/tex]
plug In the value of x ~
[tex]\qquad \sf \dashrightarrow \:2(2(5) + 1)[/tex]
[tex]\qquad \sf \dashrightarrow \:2(10 + 1)[/tex]
[tex]\qquad \sf \dashrightarrow \:2(11)[/tex]
[tex]\qquad \sf \dashrightarrow \:22 \: \: units[/tex]

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 5 to 8 . If there were 7761 total votes, how many yes votes were there?
Answer:
2,985 yes votes
Step-by-step explanation:
Ratio of yes votes to no votes was 5 to 8, we can write the following equation:
Yes : no : total = 5 : 8 : 13
Knowing the total votes was 7,761, thus the number of yes votes = (5/13) * 7,761 = 2,985 votes.

Hey! pls help me with this question on angles. would really be appreciated. have a nice day.
Using supplementary angles, it is found that the measures of the angles are given as follows:
m<a = 30º.m<b = 90º.What are supplementary angles?Supplementary angles are two angles whose sum is of 180º.
An interior angle is supplementary with it's exterior angle, hence:
m<a + 150º = 180º -> m<a = 30º.
The sum of the three interior angles of a triangle is of 180º, hence:
30º + m<b + 60º = 180º
90º + m<b = 180º
m<b = 90º.

Your supposed to try and find X. I got 20 with trial and error and it fits but I’m not sure if that’s the right answer or how to get it
Answer:
x = 20
Step-by-step explanation:
The problem tells you the relationship between time, distance, and speed. Use the given relations to find the total journey time.
__
equationtotal time = Journey A time + Journey B time
total time = (distance A)/(speed A) + (distance B)/(speed B)
total time = 15/x +6/(x+4) = 1 . . . . . using the given values
solutionMultiplying by x(x+4) we have ...
15(x +4) +6(x) = (x)(x +4)
21x +60 = x² +4x
x² -17x -60 = 0 . . . . . rearrange to standard form
(x -20)(x +3) = 0 . . . . factor the equation
x = 20 or x = -3 . . . values of x that satisfy the equation
We know the speed must be positive, so x = -3 is an extraneous solution.
The value of x is 20 (km/h).

All computers are on sale for 10% off the original price.
If x is the original price of the computer, then the function that represents the price after only a 10% discount is:
P(x) = x - 0.1x
P(x) = 0.9x
The function that gives the price, C, if only a $150 coupon is used is:
C(x) = x - 150
Choose the composition function that gives the final sale price after a 10% discount is followed by a $150 coupon.
C(P(x)) = 0.9x – 150
P(C(x)) = 0.9x – 150
C(P(x)) = 1.9x – 150
P(C(x)) = 1.9x – 150
The local machine shop hired John Dalton as a press operator his annual salary is $34,268 if John is paid weekly what is the amount of his weekly salary
Answer:
$659 weekly
Step-by-step explanation:
John Dalton earns $34,268 annually (yearly)
We want to find his weekly rate if he is paid weekly.
To do so we divide his annual salary by the number of weeks in a year (52)
So weekly rate = 34,268 / 52 = 659
A bag contains 6red balls,4 green balls,and3,blue balls if we choose a ball then another one what is the probability That the first ball will be green and the second ball be red
Total balls: 6 + 4 + 3 = 13
First pick green = total green / total balls = 4/13
adter picking the first ball there are 12 balls left.
Picking red = total red/ total balls left = 6/12 = 1/2
probability of picking both = 4/13 x 1/2 = 4/26 = 2/13

Answer:
Using 22/7 as pi, the area of a circle with a diameter of 14 metres is:
154 m²
Step-by-step explanation:
To solve, use the formula for the area of a circle.
Formula for area of a circleRemember the formula for area of a circle. Be careful not to mix up the formula for area with the formula for circumference!
[tex]A = \pi r^{2}[/tex]
From the question, we know:
π = 22/7d = 14 mTo use the formula, we need the radius ("r").
Radius ("r")The radius is a line that goes from the centre point of the circle to the circle outline. It is half the length of the diameter.
Diameter ("d")The diagram shows the diameter ("d"), which goes through the centre point of the circle. It is twice the length of the radius.
Solve for "r".
r = d/2
r = (14 m)/2
r = 7 m
Solve for area using formulaSubstitute r = 7 m and π = 22/7 into the formula for the area of a circle.
[tex]A = \pi r^{2}[/tex] Start with the formula and substitute.
[tex]\displaystyle{A = \frac{22}{7} (7\ m)^{2}}[/tex] Square "7" and the "m".
Remember that the answer for area is always squared units.
[tex]\displaystyle{A = \frac{22}{7} (49\ m^{2})}[/tex]
Multiplying a fraction and whole number is the same as multiplying the whole number in the numerator (top of the fraction).
[tex]\displaystyle{A = \frac{22*49}{7}m^{2}}[/tex] Simplify the numerator.
[tex]\displaystyle{A = \frac{1078}{7}m^{2}}[/tex] Divide.
[tex]A = 154\ m^{2}[/tex] Final answer
∴ The area of the circle is 154 m².

Step-by-step explanation:
Given information: x-int: 4 and y-int:-3
x-int point : (4,0).

Using the rule of angles in parallel lines, ∠M and ∠P are supplementary as well as ∠M and ∠N.
Since ∠M+∠P = 180° and ∠M+∠N=180°, we can conclude that ∠P and ∠N are of equal size.
∠N and ∠O are supplementary by the rules of angles in parallel lines
∠O and ∠P are supplementary by the rules of angles in parallel lines
∠N+∠O=180° and ∠O+∠P=180°
∠N and ∠P are of equal size
we deduce further that ∠M and ∠O are of equal size
Hence, the correct statement to complete the proof is
∠M ≅ ∠O; ∠N ≅ ∠P
