HOPE THIS HELPS!!! :)
PLEASE LET ME KNOW IF IM WRONG!!!
Step 2, is the subtraction property of equality, Option A is correct.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here, while reviewing the steps,
In step 2, there is an elimination of 7, by adding 7 on both side because both sides consist of -7,
When +7 add to both side, it becomes,
-7 + 7 rearranging gives, 7 - 7 = 0
Thus, Step 2, is the subtraction property of equality, Option A is correct.

Answer:
[tex]R' = 6[/tex]
[tex]S' = 7.5[/tex]
[tex]T' = 9[/tex]
Step-by-step explanation:
The question is incomplete; however the sides of the triangle are;
[tex]R = 8[/tex]
[tex]S = 10[/tex]
[tex]T = 12[/tex]
[tex]Scale\ Factor = \frac{3}{4}[/tex]

Determine the sides of R'S'T'
The new sides of the triangle is calculated as thus;
[tex]New\ Side = Old\ Side * Scale\ Factor[/tex]
Calculating R'
[tex]R' = R * Scale Factor[/tex]
Substitute 8 for R and 3/4 for Scale Factor
[tex]R' = 8 * \frac{3}{4}[/tex]
[tex]R' = \frac{24}{4}[/tex]
[tex]R' = 6[/tex]
Calculating S'
[tex]S' = S * Scale Factor[/tex]
Substitute 8 for R and 3/4 for Scale Factor
[tex]S' = 10 * \frac{3}{4}[/tex]
[tex]S' = \frac{30}{4}[/tex]
[tex]S' = 7.5[/tex]
Calculating T'
[tex]T' = T * Scale Factor[/tex]
Substitute 8 for R and 3/4 for Scale Factor
[tex]T' = 12 * \frac{3}{4}[/tex]
[tex]T' = \frac{36}{4}[/tex]

In a newspaper, it was reported that the number of yearly robberies in Springfield in 2013 was 100, and then went up by 25% in 2014. How many robberies were there in Springfield in 2014?
Answer:
125
Step-by-step explanation:
So saying something went up by 25% means that it is essentially
X + .25X
So in this case X = 100 and .25X = 25
So 100 + 25 = 125
If you're good at bearings pls help meeee with question fourteen and show full working out tyy ;)
Let
A = location of buoy 1
B = location of buoy 2
C = location of buoy 3
True north is 0 degrees on a compass bearing. Turning to 135 degrees means you turn to the south east direction exactly. Then we can break the angle down as shown in the diagram below. We have the angles 90+45+45 = 180 along the right side of location A.
Due to the fact we have parallel lines, specifically the north/south parallel lines going through A and B, we know that the green angles in the diagram are congruent. Both of which are 45 degrees. The purple angle of 45 degrees is to indicate turning to the bearing 045 degrees when you get to location B.
The green and purple angles add to 45+45 = 90, so angle ABC is 90 degrees. Triangle ABC is a right triangle.
We can use the tangent ratio to compute the angle ACB which will help us find the bearing from location 3 to location 1.
tan(angle) = opposite/adjacent
tan(C) = AB/BC
tan(C) = 4.2/2.8
C = arctan(4.2/2.8)
C = 56.3099324740202
Make sure your calculator is in degree mode
This is angle ACB. It combines with the purple angle of 45 degrees that is adjacent to point C. So we have 45+56.3099324740202 = 101.30993247402
Then this adds to 180 as this is the measure of the red arc near point C.
So, 101.30993247402+180 = 281.30993247402
The bearing is approximately 281.30993247402 degrees
Round this however you need to.

help plz
Answer:
8.5 units
Step-by-step explanation:
x is the adjacent side, the side that's 19 units is the opposite side.
Given the adj and the opp sides, use tangent.
tanθ= opp/adj
tan 66°= 19/ x
x(tan66°)= 19
x= 19/(tan 66°)
x= 8.5 units (nearest tenth)
Find the surface area of the cone represented by the net below.
31.4 in.2
43.96 in.2
394.38 in.2
56.52 in.2
Answer:
43.96 in^2
Step-by-step explanation:
The net shows the areas of the parts of the cone, so you simply need to add them up to get the total surface area.
31.4 in^2 +12.56 in^2 = 43.96 in^2
Answer:
43.96 in.2.
Step-by-step explanation:
The surface area of a cone is the triangular shape and its circular base.
In this case, the top of the cone is 31.4 inches squared in area, and the circular base is 12.56 inches squared.
So, the surface area of the cone is 31.4 + 12.56 = 43.96 inches squared.

Find the equation of the line: parallel to 3x−y=11 through (−2, 0).
Answer:
I believe it is:
slope-intercept form: y=3x+6
standard form: -3x+y=6 or 3x-y=-6
point slope-form: y-0=3(x+2)
Step-by-step explanation:
First, I put 3x-y=11 into slope-intercept form:
Subtract 3x from both sides: 3x-3x-y=11-3x
That becomes -y=-3x+11
Divide both sides by -1: -y/-1=(-3x+11)/-1
That becomes y=3x-11\
Then, the definition of a parallel line is having the same slope but different y-intercepts, so I dropped the -11 as the y-intercept, and I rewrote the equation as y=3x+b, where b is the y-intercept.
Now, I have to find the y-intercept of the parallel line, so I plug the coordinates (-2,0) into the equation for x and y to solve for the y-intercept
Write the equation out with what you have so far: y=3x+b
Substitute the coordinates (-2,0) in for x and y: 0=3(-2)+b
That becomes 0=-6+b
Add 6 to both sides: 0+6=-6+6+b
That becomes 6=b, which means that 6 is your y-intercept.
Finally, you have gathered everything you need to write the parallel line in equation format.
The parallel line's equation is
in slope-intercept form: y=3x+6
in standard form: -3x+y=6 or 3x-y=-6
in point-slope form: y-0=3(x+2)
Given: XY - tangent to circles k1(P) and k2(O) OX=16, PY=6 and OP=26 Find: XY
Answer:
XY = 24 units
Step-by-step explanation:
First of all, we need to some construction here.
Let us draw a line parallel to XY from point P towards OX, which cuts OX at point Q.
Please refer to the attached figure.
Now, Let us consider triangle OQP which is a right angled triangle, with
Hypotenuse, OP = 26 units
Height, OQ = OX - PY = 16 - 6 = 10 units
Base, PQ = ?
We can use pythagorean theorem here to find the value of PQ.
According to pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow OP^{2} = PQ^{2} + OQ^{2}\\\Rightarrow 26^{2} = OQ^{2}+10^{2} \\\Rightarrow PQ^{2} = 26^{2}-10^{2} \\\Rightarrow PQ^{2} = 676-100 \\\Rightarrow PQ^{2} = 576\\\Rightarrow PQ= 24\ units[/tex]
Now, we can see that side PQ is equal to side XY.
[tex]\therefore[/tex] XY = 24 units is the answer.

Which number is an irrational number?
Answer:
[tex]\boxed{\sqrt[3]{16} }[/tex]
Step-by-step explanation:
=> [tex]\sqrt[3]{16}[/tex] is an irrational number because it cannot be written as the form [tex]\frac{p}{q}[/tex] which is the basic requirement of being a rational number.
=> [tex]\sqrt{100}[/tex] = 10 (A rational number because it's a whole number)
=> 1/8 (Rational as it is in the form p/q)
=> -2.2675 (Rational because it is an integer)
Answer:
[tex]\boxed{\sqrt[3]{16} }[/tex]
Step-by-step explanation:
An irrational number cannot be expressed in the form p/q, where p and q are whole integers.
[tex]\sqrt{100} =10[/tex]
[tex]\frac{1}{8} =0.125[/tex]
[tex]-2.2675= - \frac{907}{400}[/tex]
[tex]\sqrt[3]{16} \approx 2.51984209979... \neq \frac{p}{q}[/tex]
[tex]\sqrt[3]{16}[/tex] is an irrational number.

If the trapezoid is reflected over the line segment BC, what will be the new coordinates of point A?
Answer:
(13,15)
Step-by-step explanation:
If the trapezoid were to be reflected over the line segment BC, the new coordinates of point A would be (13,15) as it moves to right 5 points from BC sides.
Answer:
(B) 13,15
Step-by-step explanation:
If we look at point A in relation to point B, we see that it's 5 units to the left and 3 units down from point B, therefore making it at (3,15). Now, if we reflect across line BC (which is a y-axis) then we change the X value, not the y value. If the line BC is located at X=8, then the X value will be 8+5, since point A is 5 units away from the line BC. The y value will stay the same because we are reflecting over only one axis. 8+5 = 13, and the y stays at 15, so the new point value of A would be (13,15).

A normal distribution has a mean of 60 and a standard deviation of 2. Determine the z-
score for the data value of 22.
Answer: z score is -19
Work Shown:
x = 22 is the raw score
mu = 60 is the mean
sigma = 2 is the standard deviation
z = (x-mu)/sigma = formula to find z scores
z = (22 - 60)/2
z = -38/2
z = -19
The z score of -19 means we are 19 standard deviations below the mean. Anything beyond 3 standard deviations is often considered unusual/rare as most of the data in the normal distribution is within 3 standard deviations (approximately 99.7% of the distribution)
