Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

Actually Welcome to the Concept of the Rotational symmetry.
To get the rotate image as same, the smallest possible degree rotation is 90°
===> Answer is 90°
Which of the following describes the transformation from Figure 1 to Figure 2?
9514 1404 393
Answer:
Rotation 90° CCW
Step-by-step explanation:
Note that Figure 1 has a small appendage off the larger rectangle. That appendage is pointing East (to the right).
In Figure 2, that same appendage is pointing North (up).
If you are facing East and you want to face North, you will find that you need to turn 90° in the counterclockwise direction. That is the transformation that was done here:
rotation 90° CCW about the origin
Answer:
A rotation of 90° counter-clockwise around the origin

The tip of a 8 cm minute hand of a clock sweeps out circular arcs. What is the length of the arc made by the tip of the minute hand between 3:12 and 3:32? Use 3.14 for pi. Round your answer to the nearest hundredth. Enter your answer in the box. cm
Answer:
16.75 cm
Step-by-step explanation:
Substitute into the formula.
x/2 π = 120/360
Solve.
x/2 π*8 = 120/360
x/16 π = 1/3
3x = 16 π
X = 16 π/3
X = 16*3.14/3
X = 16.746666666666666666666666666667
X = 16.75

In the coordinate plane, the point X (-4,-4) is translated to the point X'(-6, 0). Under the same translation, the points
Y(0, 0) and Z (-1, -6) are translated to Y' and Z', respectively. What are the coordinates of Y' and Z'?
Answer: coordinate x is translated 2 unit left and the coordinate y is translated 4 units down
so y(5, -2) .......y' (3, -6)
z (0,0)...........z'(-2, -4)

Can someone give me the answer to this please?
Answer:
C
Step-by-step explanation:
Answer:
ok so its C bc 8 x 0.5 = 4 and so there are 4 long rectangles so multiply by 4 which is 16 bc 4 x 4 = 16 next find the area of the 2 squares 0.5 x 0.5 =0.25
multiply that by 2 because there are 2 squares which is 0.5 and so
16+0.5= 16.5 in²

Tickets to Disney World are $100. The price is going to increase on
January 1. What is the percent of change if the cost increases to a $142?
Answer:
42%
Step-by-step explanation:
Answer:
42%
Step-by-step explanation:
To find the percent change, divide the difference in the prices by the original price
42/100
= 0.42
So, the percent change was 42%

Step-by-step explanation:

Supplementary angles = 180º (theorem)
Set <ABD + <DBC = 180º
2x + (x+24) = 180º
add like terms = 3x+24=180
3x=156
x = 52
now plug in x for both angles
<ABD = 2(52) = 104
<DBC = 52+24 = 76
14.
complementary angles = 90º (theorem)
set <EFG + <GFH = 90º
y-32 + y = 90
2y - 32 = 90 : combine like terms
2y = 122
y = 61
now plug in y for both angles
<EFG = 61-32 = 29
<GFH = 61
15.
Vertical angles are equal to each other (theorem)
<PQR = <TRS
38 = 5w-7
45 = 5w
w = 9
plug into <TRS
<TRS = 5(9) - 7 = 38
(Also since you know that <PRQ is 38 and that the measure has to be the same for both angles, it can be assumed without algebra that <TRS would be 38º)

Ms. Gilmore, a fifth-grade teacher, hangs a paper chain around the perimeter of the
classroom to count down the days in the school year. On the first day of school, the paper
chain has 180 links. Each link is 3 inches long. How many feet long is the paper chain on the
first day of school?
9514 1404 393
Answer:
45 feet
Step-by-step explanation:
Each link is 3/12 foot or 1/4 foot. Then 180 links will total ...
180(1/4 ft) = 45 ft
The paper chain is 45 feet long the first day of school.

35 is what percent of 150? Enter your answer in decimal form to the nearest hundreth.
Answer:
23.33%
Step-by-step explanation:
Solution for 35 is what percent of 150:
35: 150*100 =
(35*100): 150 =
3500: 150 = 23.33
Now we have: 35 is what percent of 150 = 23.33
Question: 35 is what percent of 150?
Percentage solution with steps:
Step 1: We make the assumption that 150 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=150.
Step 4: In the same vein, x%=35.
Step 5: This gives us a pair of simple equations:
100%=150(1).
x%=35(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
\frac{100\%}{x\%}=\frac{150}{35}
Step 7: Taking the inverse (or reciprocal) of both sides yields
\frac{x\%}{100\%}=\frac{35}{150}
Therefore, 35 is 23.33% of 150.
if [tex]cosA=\frac{2}{5}[/tex] and [tex]tanA\ \textless \ 0[/tex] then [tex]sin(2A)=?[/tex]
Please help
Absurd answers will not be tolerated
Answer:
[tex]\displaystyle \sin(2A)=\frac{-4\sqrt{21}}{25}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \cos(A)=\frac{2}{5}\text{ and } \tan(A)<0[/tex]
And we want to determine the value of:
[tex]\sin(2A)[/tex]
First, since cos(A) is positive and tan(A) is negative, this means that ∠A must be in QIV.
In QIV, cosine is positive, sine is negative, and tangent is also negative.
The given ratio tells us that the adjacent side to ∠A is 2, and the hypotenuse is 5.
Then by the Pythagorean Theorem, the opposite side will be given by:
[tex](2)^2+o^2=(5)^2[/tex]
Solve for the opposide side:
[tex]o=\sqrt{5^2-2^2}=\sqrt{21}[/tex]
So, with respect to ∠A, the adjacent side is 2, the opposite side is √(21), and the hypotenuse is 5.
Using the double-angle identity, we can rewrite our original expression as:
[tex]\sin(2A)=2\sin(A)\cos(A)[/tex]
Using the above information, substitute in values. Remember that cosine is positive and that sine is negative:
[tex]\displaystyle \sin(2A)=2\Big(-\frac{\sqrt{21}}{5}\Big)\Big(\frac{2}{5}\Big)[/tex]
Simplify. Therefore:
[tex]\displaystyle \sin(2A)=\frac{-4\sqrt{21}}{25}[/tex]
Answer:
sin 2A=2sin Acos A
=2×2/5×√21/5=±4√21/25
Step-by-step explanation:
cos A=2/5
B/H=2/5
corresponding value we get
B=2
H=5
by using Pythagoras law
H²=P²+B²
5²=P²+2²
P²=25-4
p=√21
now
sin A=P/H=√21/5
now
sin 2A=2sin Acos A=2×2/5×√21/5=±4√21/25

y = [tex]\frac{1}{2}x - 2[/tex] for slope-intercept form y = mx + b, where m is the slope and b is the y intercept. The line intercepts the y axis (y intercept) at -2, and the slope is the rise over the run, and the rise is 1 and the run is 2 so the slope is 1/2.

If x varies as y and if x=20 when y=9 , find x when y=18
Answer:1/2 y
Step-by-step explanation:
We can solve this using ration reasoning:
x
2
x
1
=
y
2
y
1
Explanation:
If
x
varies directly with
y
(written
x
∝
y
), then doubling
y
means doubling
x
, so the rations of final values and initial values will be the same:
x
2
x
1
=
y
2
y
1
In this case,
x
2
9
=
24
18
x
2
=
9
⋅
24
18
=
12
Or, intuitively, if
x
∝
y
and
x
=
9
when
y
=
18
, we can conclude that
x
=
1
2
y
and
1
2
of 24 is 12.
