Answer:
[tex] - x = 20 \\ so \: x \: will \: be \: = - 20[/tex]
Hope it helps!
Answer: x = -20
Step-by-step explanation:
Question: If -x = 20, then x = ?
Multiply both sides of the equation by -1
(-1)(-x) = (-1)(20)
Simplify (remember that multiplying two negative numbers equals a positive number)
x = -20

Answer:
80 degrees
Step-by-step explanation:
The only given angle here is angle 4, which measures 100 degrees.
1) Identify angle relationships
Angle 4 and angle 6 are interior angles, meaning they have a sum of 180 degrees.
2) Solve for angle 6
180-Angle 4=Angle 6
180-100=Angle 6
80=Angle 6
Therefore, the measure of angle 6 is 80 degrees.
I hope this helps!
Answer:
c. 80°
Step-by-step explanation:
We are given a shape with a bunch of lines, and are asked to find what measure is ∠6.
Solving this is simple, we just need to keep notice that what angle is larger than 90 degrees looks like and what under 90 degrees looks like. All angles that are above 90 look wide and huge, while all under is very tiny and skinny.
If we take a look at our hint, angle 4 has the (100 degrees). Look at how wide it is, if angle 6 is tinier than that, then the answers A. and B. are scratched out.
Now 90 degrees is a right angle, looking at angle 6 guarantees that D. is also not correct because it is not a right angle.
Leaving us with C. 80

Answer:
B.
Step-by-step explanation:
The answer is B because 3/5 of 1/2 is less than 1/2. The equation that represents this problem is
3/5 x 1/2 = 3/10
3/10 < 1/2
Therefore, 3/5 is less than 1/2!

The volume of the pyramid is 8in3. What is the height of the pyramid? (Sides are 5in and 4in)
Answer:
h = 0.4 inches
Step-by-step explanation:
Given that,
The volume of the pyramid is 8 in³.
The sides of the pyramid are 5 in and 4 in.
We need to find the height of the pyramid.
The formula for the volume of pyramid is given by :
V = lbh
Where h is the height of the pyramid
So,
[tex]h=\dfrac{V}{lb}\\\\h=\dfrac{8}{5\times 4}\\\\h=0.4\ in[/tex]
So, the height of the pyramid is 0.4 inches.
Given that sec(θ)=5/3 and θ is in Quadrant I, what is tan(θ)? Write your answer in exact form. Do not round.
9514 1404 393
Answer:
tan(θ) = 4/3
Step-by-step explanation:
The relationship between secant and tangent is ...
1 +tan² = sec²
The the tangent of the angle is ...
tan(θ) = √(sec²(θ) -1)
tan(θ) = √((5/3)² -1) = √(16/9)
tan(θ) = 4/3

Triangle A’B’C’ is a dilation image of triangle ABC. Which is the correct description of the dilation?
A. Center C and scale factor 4
B. Center A and scale factor 4
C. Center A and scale factor 5
D. Center C and scale factor 5
Answer:
B.
Step-by-step explanation:
Center is the point that does not change and that point is A. To find the scale factor you just divide the translated length by the original, in this case, 8÷2 which gives a scale factor of 4.

Answer:
Area of sector of a circle = 28.26 meter²
Step-by-step explanation:
Given:
Side of cube = 12 meter
One white section = sector of a circle
Find:
Area of one white section
Computation:
Radius of circle = Side of cube / 2
Radius of circle = 12 / 2
Radius of circle = 6 meter
One white section = sector of a circle
Area of sector of a circle = [θ/360][π][r]²
Area of sector of a circle = [90/360][22/7][6]²
Area of sector of a circle = [0.25][3.14][36]
Area of sector of a circle = 28.26 meter²

482 – 412 + 286 - 12 x 204solve
Answer:
70,176
Step-by-step explanation:
Given that
482 - 412 + 286 - 12 × 204
We need to solve the above equation
= 482 - 412 + 286 - 12 × 204
= 70 + 286 - 12 × 204
= 356 - 12 × 204
= 344 × 204
= 70,176
Hence, the answer to the given equation is 70,176

Jose can eat 5/8 of a pizza in 1/4 hours. How many hours will it take him to eat the whole pizza?
Answer: 2/5 of an hour
Step-by-step explanation:
ok so 5/8 = .625 just to begin with...
and as a ratio it would be .625 = .25
8/8 (1)
So I did .25x1=.25
.25x.625= 0.4 or as a fraction 2/5

Answer:
Step-by-step explanation:
A) WX=YX
angle w =angle Y=70
X=180-2x70= 40
B) all sides are equal. Angle V=T=U=180/3=60
(a) the given triangle is a isosceles triangle. The two base (non-congruent side) angles (in this case, ∠XYW & ∠XWY) will have the same measurements.
It is given that m∠XYW = 70°, therefore, m∠XWY is also 70°.
Subtract 180 from the two 70° to get m∠X:
180 - (70 + 70) = 180 - 140 = 40°
m∠X = 40° is your answer.
~
The given triangle is a equilateral triangle (All sides are congruent). If all sides are congruent, it is a equilateral triangle, and if it is a equilateral triangle, then all measurements of the inside angles are the same, 60°
m∠V = 60°

A machine fills 24-ounce (according to the label) boxes with cereal. The amount deposited
into the box is normally distributed with a standard deviation of 0.25 ounce. What does the
mean have to be in order for 99.5% of the boxes to contain 24 ounces or more of cereal?
Answer: We do not know the mean but we do know the standard deviation which is 0.25 ounces. The normal distribution plot below shows the shaded
region at approximately 5% of the area of the total Gaussian distribution.
From a Table we find that 5% is a z = -2.57 and so the mean must be 2.57
multiplied by 0.25 ounces = 3.57 0.25 = 0.643 ounces. The mean value
of box must be 0.643 ounces above the declared 24 ounces. Thus,
Mean value = = 24.643 ounces
Step-by-step explanation:
In a random sample of 5 residents of the state of Maine, the mean waste recycled per person per day was 2.6 pounds with a standard deviation of 0.69 pounds. Determine the 98% confidence interval for the mean waste recycled per person per day for the population of Maine. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answer:
(1.307 ; 3.893)
Step-by-step explanation:
Given that:
Mean, xbar = 2.6
Standard deviation, s = 0.69
Sample size, n = 5
Confidence interval : xbar ± margin of error
Margin of Error = Tcritical * s/sqrt(n)
Degree of freedom (df) = n - 1 = 5 - 1 = 4
Hence Tcritical = 3.747
Margin of Error = 3.747 * 0.69/sqrt(4)
Margin of Error = 1.293
Lower boundary = (2.6 - 1.293) = 1.307
Upper boundary = (2.6 + 1.293) = 3.893

At the Virgin Music store in Times Square, 60 people entering the store were selected at random and were asked to choose their favorite type of music. Of the 60, 12 chose rock, 16 chose country, 8 chose classical, and 24 chose something other then rock, country, or classical. Determine the empirical probability that the next person entering the store favors
(a) rock music.
(b) country music.
(c) something other then rock, country, or classical music.
Answer:
A) 20%.
B) 26.66%.
C) 40%.
Step-by-step explanation:
Since at the Virgin Music store in Times Square, 60 people entering the store were selected at random and were asked to choose their favorite type of music, and of the 60, 12 chose rock, 16 chose country, 8 chose classical, and 24 chose something other then rock, country, or classical, to determine the empirical probability that the next person entering the store favors (a) rock music, (b) country music, and (c) something other then rock, country, or classical music, the following calculation must be performed:
A)
60 = 100
12 = X
12 x 100/60 = X
1200/60 = X
20 = X
Therefore, the probability that the next person favors rock music is 20%.
B)
60 = 100
16 = X
16 x 100/60 = X
1600/60 = X
26.66 = X
Therefore, the probability that the next person favors country music is 26.66%.
C)
60 = 100
24 = X
24 x 100 / 60 = X
2400 / 60 = X
40 = X
Therefore, the probability that the next person favors another type of music is 40%.
How do I graph the line with slope of 3 and Y-intercept if -6?
Step-by-step explanation:
For drawing the graph , we Firstly need to find the equation of the line . We can find the line using Slope intercept form . Here ,
y intercept = (-6)slope = 3 .We know slope intercept form as ,
[tex]\implies y = mx + c \\\\\implies y = (3)x + (-6) \\\\\implies \boxed{\boxed{y = 3x - 6 }}[/tex]
Now we need to plot the graph of y = 3x -6. Refer to attachment for graph .
