HELP NOW PLS EXTRA POINTS!!
Find the measure of the exterior angle. (Only put a number value for your
answer)
Answer:
X° + 44° = 2x° + 11° [ Sum of two adjacent interior angles of a triangle = opposite exterior angle]
=> - x° = 11°-44°
=> -x° = -33°
=> x° = 33°
Therefore the value of x° = 33°

The January record high temperature in Austin, Texas is 92 degrees. The January record low temperature is -1 degree. What is the difference between the record high and low temperatures?
Answer:
93
Step-by-step explanation:
The forecast high is the highest temperature expected to occur that day, which in most cases is in the afternoon. When referring to the recorded high/low from a previous day, the high and low-temperature values are the actual temperature extremes that were recorded during that 24-hour calendar day.
Given: Texas is 92 degrees. January's record low temperature is -1 degrees.
To find: What is the difference between the record high and low-temperatures?
Solution: Subtract -1 from 92, 92 - (-1) = 93
3 security guards below whistle at interval of 50 minutes, 60 minutes and 100 minutes if they blow together at 1:00am,at what time will they blow together again
Answer:
They will blow together again at 6:00 am
Step-by-step explanation:
Guard 1 whistles every 50 minutes.
Guard 2 whistles every 60 minutes.
Guard 1 whistles every 100 minutes.
Assuming that at the beginning they whistle together, the next time that they will whistle together is after the smallest common multiple of 50, 60, and 100.
Because one of the numbers is 100, it only has multiples like:
100*2 = 200
100*3 = 300
100*4 = 400
etc...
So we need to find a common multiple of 50 and 60 that is also a multiple of 100.
For example, the multiples of 50 that are also multiples of 100 are:
50*2 = 100
50*4 = 200
50*6 = 300
And the multiples of 60 that are also multiples of 100 are:
60*5 = 300
(this is the only one)
Then we can see that a common multiple of 50, 60 and 100 is 300.
Then they will whistle together 300 minutes after the first common whistle.
We know that they blow together at 1:00 am
300 minutes after it is:
First, we need to write 300 minutes in hours.
We know that one hour has 60 minutes.
then 300 minutes = (300 minutes/60 minutes) hours = 5 hours.
300 minutes after 1:00 am is the same as 5 hours after 1:00 am
And 5 hours after 1:00 am is 6:00 am
They will blow together again at 6:00 am
Evaluate the equation: e - 3.1 = 5
A. e = 1.9
B. e = 2.1
C. e = 8.1
D. e = 8.5
Answer:
C. e = 8.1
Step-by-step explanation:
e-3.1= 5
e = 5+3.1
e = 8.1
What is the surface area of the composite figure? Round to the nearest tenth.
Answer:
2855.0
Step-by-step explanation:
there are several surface areas.
1. outside surface of the cylinder = circle circumference times height = 2*pi*r*height = 2*pi*14*14 = 1231.5
2. top and bottom of the cylinder = circle area times 2 = pi*r^2 * 2 = pi*14^2 *2 = also 1231.5
3. subtract the 2 cut out rectangles on the top and the bottom = 2* 6*14 = 168
4. add the areas of the inside walls of the cut out block.
there are 2 narrow rectangles = 2* 6*14 = 168
there are 2 squares = 2* 14*14 = 392
so, 1.+2.-3.+4. = 2855.0 (2855.00864...)

Find the lengths of the diagonals of rectangle WXYZ.
WY = 62 – 7
XZ = 3x + 2
The length of each diagonal is
units.
According to the question,
WY = (6x - 7) unitsXZ = (3x + 2) unitsAs we know that,
❖ Diagonals of a rectangle are equal.
[tex] \\ \twoheadrightarrow \sf { WY = XZ} \\ [/tex]
[tex] \\ \twoheadrightarrow \sf { 6x - 7 = 3x +2} \\ [/tex]
[tex] \\ \twoheadrightarrow \sf { 6x - 3x = 2 + 7} \\ [/tex]

[tex] \\ \twoheadrightarrow \sf {x =\dfrac{9}{3} } \\ [/tex]
[tex] \\ \twoheadrightarrow \bf\underline { x = 3} \\ [/tex]
Therefore,

Since, WY = XZ[tex] \\ \twoheadrightarrow \sf { WY \; \& \; XZ = 3(3) + 2 \; units} \\ [/tex]
[tex] \\ \twoheadrightarrow \sf { WY \; \& \; XZ = 9 + 2 \; units} \\ [/tex]

Therefore, length of each diagonal is 11 units.

Is -2 rational or irrational?
Answer:
Rational
Step-by-step explanation:
Rational. It can be expressed as a fraction, which is the definition of a rational number.
Hope this Helps!
-2 is rational
This is because every negative integer is a negative rational number.
We know that -1 = -1/1, -2 = -2/1, -3 = -3/1, -4 = -4/1 and so on …….
In other words, any negative integer n can be written as n = n/1, here n is negative and 1 is positive.
So, negative 2 is rational.
A chord consists of notes that sound good together. The C major chord, starting at middle C, has the following
frequencies:
C-262 Hz
E-330 Hz
G-392 Hz
a.
Determine the ratio of the frequency of G to C. Express the answer in a simple integer ratio. (Due to rounding the ratio
will be approximate.) How many G waves will fit in the length of four C waves?
6
b. 5
c. 4
d. 3
Please select the best answer from the choices provided
Answer:
D. 3
Step-by-step explanation:
I mathed it
Answer:
To determine the ratio of the frequency of G to C, we divide the frequency of G by the frequency of C:
G/C = 392/262
Simplifying the ratio by dividing both numbers by 2, we get:
G/C = 196/131
This is an approximate ratio, since we rounded the frequencies to the nearest whole number.
To find out how many G waves will fit in the length of four C waves, we need to compare the wavelengths of the two notes. The wavelength is the distance between two corresponding points on a wave, such as the distance between two peaks or two troughs.
The wavelength is inversely proportional to the frequency, so we can use the ratio of frequencies we found above to determine the ratio of wavelengths:
λ(G)/λ(C) = f(C)/f(G) = 262/392 = 0.668
This means that the wavelength of G is about 0.668 times the wavelength of C. Since the frequency of G is higher than the frequency of C, we can also say that G has more waves per second than C.
To find out how many G waves fit in the length of four C waves, we need to multiply the wavelength of G by the number of waves in four C wavelengths:
4λ(C)/λ(G) = 4/(λ(G)/λ(C)) = 4/0.668 ≈ 5.988
So, approximately 6 G waves fit in the length of four C waves.
Therefore, the answer is (A) 6

Find the exact values of sinø , cosø, and tanø if the terminal side of ø in standard position contains the given point.
P(-3,4)
I need sinø, cosø, and tanø please.
Answer:
See below for answers and explanations
Step-by-step explanation:
Given P(-3,4) we can solve for the third side:
c=√[(-3)²+4²]
c=5
If the terminal side of ø in standard position contains the given point, then it is located at that point, making -3 the opposite side (the side length is 3), 4 the adjacent side, and 5 the hypotenuse.
Therefore:
cos∅=adjacent/hypotenuse=4/5
sin∅=opposite/hypotenuse=3/5
tan∅=opposite/adjacent=3/4
A sculpture is made of solid nickel in the shape of a cone. The sculpture is 84 inches tall, and its base has a radius of 8 inches. If nickel costs $2.25 per cubic inch, how much did the nickel for the sculpture cost?
Use 3.14 for π, and do not round your answer.
Answer:
Cost = $12660.48
Step-by-step explanation:
Given that,
The height of the cone shape, h = 84 inches
The radius of base, b = 8 inches
The cost per cubic inch is $2.25.
The cost of nickel for the sculpture is given by :
[tex]C = 2.25\times \dfrac{1}{3}\pi r^2 h\\\\=0.75\times 3.14\times 8^2\times 84\\\\C=\$12660.48[/tex]
So, the required cost is equal to $12660.48.

Answer:
16. Angle 2 is 30° and angles 1 & 3 are 150°
17. Equilateral (all sides are equal)
18. A, B, D
19. A, B. (8 angles and all sides are congruent)
20. False.
Step-by-step explanation:
angle 2 is a corresponding (ish) angle to the one marked 30°, so they are the same. and then the other angle is supplementary to the 30° one, therefore they must add up to 180 degrees. 180-30= 150 so that is angle 1 and 3.
Answer:
question 1 - angle 1 and 2 the answer is 150 and angle 3 is 30
question 2 - the triangle is an equilateral
Question 3 - A,B,D
question 4 - A,B
