Find each angle measure
Answer:
a) UXW = 78 b) UWY = 48 c) WZX = 48 d) XYZ = 42
Step-by-step explanation:
There are many ways you can do this, but I'll just describe one for each.
a) Angle YWV is vertical to XWZ, so they are congruent. Angle XWZ is an alternate interior angle with angle UXW, so UXW = 78.
b) All the angles that revolve around point W must add up to 360. We already know 4 angles due to vertical angles, so 78 + 78 + 54 + 54 = 264.
360 - 264 = 96. There are two angles left, and since they are vertical they must be congruent. 96/2 = 48, so angle UWY is 48 degrees.
c) We already know that the angle vertical to UWY is 48, so WZX is also 48 degrees because they are alternate interior angles.
d) Angle UWY is 48 degrees and angle WUY is 90 degrees because of the perpendicular line. Now we can find XYZ, the remaining angle.
90 + 48 = 138. 180 - 138 = 42. So XYZ = 42 degrees.
I hope this helped. I'm open to any questions you may have. :)
Answer:
a) UXW = 78 degrees
b) UWY = 48 degrees
c) WZX = 48 degrees
d) XYZ = 42 degrees
Step-by-step explanation:
Apply rules and theorems:
Angles in a triangle add up to 180 degrees.
Angles on a straight line add up to 180 degrees.
Right angles are 90 degrees.
Vertically opposite angles are equal.
With these we can solve for the angles.

A city has a population of 380,000 people. Suppose that each year the population grows by 6.25 % . What will the population be after 8 years? Round to the nearest whole number.
After 8 years, the city's population will be 538,156 people.
To calculate the population after 8 years, we can use the formula for compound interest:
\[A = P(1 + r)^n\]
Where:
A = Future population
P = Initial population (380,000)
r = Annual growth rate (6.25% or 0.0625 as a decimal)
n = Number of years (8)
Plugging in these values:
\[A = 380,000(1 + 0.0625)^8\]
\[A ≈ 538,156\]
So, the population of the city after 8 years will be approximately 538,156 people.
To calculate the population after 8 years, we used the formula for compound interest, as population growth can be thought of as compounding annually.
The initial population of 380,000 is multiplied by the growth factor, which is calculated by adding 1 to the annual growth rate expressed as a decimal (0.0625).
This factor is then raised to the power of the number of years (8).
The result is approximately 538,156, rounded to the nearest whole number. This means that with an annual growth rate of 6.25%, the city's population will increase to around 538,156 people after 8 years.

The population in 8 years will be 663,994 people.
To find the population of a city after 8 years given a 6.25% annual growth rate, we use the formula for exponential growth:
Population = P(1 + r)^t
where:
P is the initial populationr is the growth rate (expressed as a decimal)t is the time in yearsGiven:
P = 380,000r = 0.0625t = 8Substitute the values into the formula:
Population = 380,000 * (1 + 0.0625)⁸
Calculate:
1 + 0.0625 = 1.0625(1.0625)⁸ ≈ 1.74742Population ≈ 380,000 * 1.74742 ≈ 663,994Rounding to the nearest whole number, the population after 8 years will be 663,994 people.
The diameter of your bicycle wheel is 34 inches. What is it’s radius
The diameter of a circle (or in this case a bicycle wheel) is how long it is from one side of the circle striaght across to the other side. The radius is half the diameter. So if the diameter is 34, then the radius would be 17.
17 inches
Diameter = 2 * radius
So you can rewrite that as
Radius = diameter / 2
34/2=17
Sierra listened to her playlist for 10 minutes. She listened to 3 songs. The first song lasted 192 seconds, and the second song lasted 231 seconds. How long was the third song?
Answer:
177 Seconds
Step-by-step explanation:
192 + 231 =423
10 minutes is equal to 600 seconds because there are 60 seconds in every minute.
600 - 423 = 177
Final answer:
Sierra listened to a total of 600 seconds of music. After subtracting the length of the first two songs (192 seconds + 231 seconds = 423 seconds), we find the third song was 177 seconds long.
Explanation:
Sierra listened to her playlist for 10 minutes, or 600 seconds, as there are 60 seconds in a minute. She listened to 3 songs where the first song lasted 192 seconds and the second song lasted 231 seconds. To find out how long the third song was, we need to subtract the length of the first two songs from the total listening time.
The total length of the first two songs is 192 seconds + 231 seconds = 423 seconds.
So, the length of the third song is 600 seconds - 423 seconds = 177 seconds, which means the third song lasted for 177 seconds.
a right triangle has a leg of 11cm and a hypotenuse of 17cm what is the length of the other leg round to the nearest tenth
Answer: [tex]2\sqrt{42}cm[/tex] ≈12.96 cm
Step-by-step explanation:
To solve this exercise you must apply the Pythagorean Theorem, which is the shown below:
[tex]a^2=b^2+c^2[/tex]
Where a is the hypotenuse and b and c are the other legs.
You know that the triangle has a leg of 11 cm and the hypotenuse is 17 cm. Therefore, you can substitute values and solve for the other leg.
Then you obtain:
[tex](17cm)^2=b^2+(11cm)^2\\b=\sqrt{(17cm)^2-(11cm)^2}\\b=2\sqrt{42}cm[/tex]
b≈12.96 cm

7 1/2 divided by 1 9/10 simplified
Answer:
[tex]\large\boxed{3\dfrac{18}{19}}[/tex]
Step-by-step explanation:
[tex]\text{First step:}\\\text{Convert the mixed number to the improper fractions:}\\\\7\dfrac{1}{2}=\dfrac{(7)(2)+1}{2}=\dfrac{15}{2}\\\\1\dfrac{9}{10}=\dfrac{(1)(10)+9}{10}=\dfrac{19}{10}\\\\7\dfrac{1}{2}:1\dfrac{9}{10}=\dfrac{15}{2}:\dfrac{19}{10}\\\\\text{Dividing by a fraction is the same as multiplying by the inverse of a fraction}\\\\=\dfrac{15}{2}\cdot\dfrac{10}{19}=\dfrac{15}{2\!\!\!\!\diagup_1}\cdot\dfrac{10\!\!\!\!\diagup^5}{19}=\dfrac{15}{1}\cdot\dfrac{5}{19}=\dfrac{75}{19}=3\dfrac{18}{19}[/tex]
First, convert the mixed fractions into improper fractions. Then, turn the division problem into a multiplication problem by utilizing the concept of reciprocal. This gives us 75/19, or about 3.95 in decimal.
We first need to convert the mixed fractions into improper fractions. To do this, we multiply the whole number by the denominator of the fractional part and then add the numerator, placing this sum over the original denominator. This makes 7 1/2 into 15/2 and 1 9/10 into 19/10. The division problem 7 1/2 divided by 1 9/10 simplifies to 15/2 divided by 19/10.
Next, we remember that dividing by a fraction is the same as multiplying by its reciprocal. The reciprocal of a fraction is obtained by swapping the numerator and denominator. So, we change our division problem into a multiplication problem, transforming 15/2 divided by 19/10 into 15/2 * 10/19.
After multiplying these fractions, we get 150/38, which simplifies to 75/19, which is approximately 3.95 when converted to decimal.

The value of x is ___________.
Recall that the sum of all interior angles in a triangle is 180°, and that a flat-line is always 180°.
Check the picture below.
The value of x is ?
Answer:
96°
Step-by-step explanation:
so we are given two angles, we can use the two angles that were given to find the angles inside the triangle (2 of them)
then once we find those two angles in the triangle, we can use those to find the third angle
then we can figure out what x is
so both a straight line and a triangle are 180°
angle 1: 180°-134° = 46°
angle 2: 180°- 130° = 50°
now we add the two angles together: 46° + 50° = 96°
one triangle = 180°
180° - 96° = 84° = angle 3
now we can find x by subtracting 84° from 180°
180°-84° = 96°
Answer:
x = 96 degrees
Step-by-step explanation:
As you know the sum of a set of exterior angles is 360 degrees
so
x + 130 + 134 = 360
x + 264 = 360
x = 360 - 264
x = 96

The formula for the volume of a sphere is V=4/3nr3 . What is the formula solved for r
V = 4/3 π r^3 //Multiply both sides by 3 and divide both sides by 4.
3V/4 = π r^3 //Divide both sides by π
(3V)/(4π) = r^3 //Cube root on both sides.
3√ (3V/4π)
NOTE: 3√ means cube root and not 3 times square root. Everything inside the root is cube root (3V)/(4π).
