Answer:
x=90
y=148
Step-by-step explanation:
Since we know a line is 180 degrees, and we know that angle Q is 90, x must be a 90-degree angle as well.
With our given information we can add up the two given angles in the triangle which are 90 and 58
90+58=148
To find what R is, we must subtract 148 from 180 because all the angles in a triangle sum up to 180.
180-148=32
Now that we know that R is 32, because we know that a line is 180 degrees, we can subtract 32 from 180 to get our final answer for y as 148.
180-32=148
What is the radius and diameter of the following circle?
Radius = cm
diameter= cm
The value of diameter and radius of circle is 7 cm and 3.5cm.
According to the statement
we have given that the a figure of circle and we have to find the radius and the diameter of the circle.
So, We know that the
The radius of a circle runs from its center to its edge, the diameter runs from edge to edge and cuts through the center.
Here from the figure it is clear that the
Diameter of circle = 7cm
and the radius of circle we have to find
So,
Radius of circle = Diameter /2
Substitute the values in it then
Radius of circle = 7cm /2
Radius of circle = 3.5 cm.
So, The value of diameter and radius of circle is 7 cm and 3.5cm.

Consider a triangle ABC
like the one below. Suppose that a=75, b=63, and c=69.
The figure is not drawn to scale.) Solve the triangle.
round your answers to the nearest tenth.
If there is more than one solution, use the button labeled "or".
The given triangle has three angles with measurements: ∠A = 69°, ∠B = 52°, and ∠C = 59° respectively. Using the law of cosines, these angles are calculated from the given lengths of the triangle.
What is the law of cosines?The law of cosines gives the relationship between the lengths of sides and the angles of the triangle ABC.
According to the law of cosines:
Cos A = (b² + c² - a²)/2bc
Cos B = (a² + c² - b²)/2ac
Cos C = (a² + b² - c²)/2ab
Calculation:For the given triangle ABC,
a = 75, b = 63, and c = 69
So, using the law of cosines,
Cos A = (b² + c² - a²)/2bc
⇒ Cos A = (63² + 69² - 75²)/2×63×69
⇒ Cos A = 5/14
⇒ A = Cos⁻¹(5/14) = 69.07
∴ ∠A = 69°
Similarly,
Cos B = (a² + c² - b²)/2ac
⇒ Cos B = (75² + 69² - 63²)/2×75×69
⇒ Cos B = 31/50
⇒ B = Cos⁻¹(31/50) = 51.6 ≅ 52
∴ ∠B = 52°
Cos C = (a² + b² - c²)/2ab
⇒ Cos C = (75² + 63² - 69²)/2×75×63
⇒ Cos C = 179/350
⇒ C = Cos⁻¹(179/350) = 59.2
∴ C = 59°
Thus, the angles of the triangle ABC are 69°, 52°, and 59° respectively.

Answer: If they worked together, it would take 31.5 minutes
Step-by-step explanation:
There's a certain formula for equations like this:
[tex]\frac{1}{t1} +\frac{1}{t2}=\frac{1}{tb}[/tex]
t1= the time it took for the first person to complete the task.
t2= the time it took for the second person to complete the task.
tb= the time it took for both of them to complete the task.
We have the values for both t1 and t2, but not for tb.
t1= 45
t2= 105
tb= x
[tex]\frac{1}{45} +\frac{1}{105} = \frac{1}{x}[/tex]
Now it's simple algebra, and all we need to do is solve for x
The LCM for both fractions is 315, so now we multiply BOTH sides of the equation by 315.
[tex]\frac{315}{45} + \frac{315}{105} = \frac{315}{x}[/tex]
This will simplify nicely, so now we just need to get x on the other side.[tex]7 + 3 = \frac{315}{x} \\\\\ 10*x = \frac{315}{x} * x[/tex]
[tex]10x = 315 \\\\x = 31.5[/tex]
A rectangle is 6x-4 feet long and 2x + 3 feet wide. What is the perimeter of the rectangle?
Answer:
Perimeter o the rectangle = 16x - 2
Step-by-step explanation:
Perimeter of a rectangle = 2(long+ wide)
Then:
Perimeter = 2((6x-4)+(2x+3))
Perimeter = 2(6x+ 2x + 3 - 4)
Perimeter = 2(8x - 1)
Perimeter = 2*8x + 2*-1

BPaolo helped in the community garden for 2 3/4 hours this week. This was 1 5/6 equal length shift, because Paolo stopped early one day when it started to rain. How long is a single shift?
If 2+3/4 hours is equal to 1+5/5 equal length shift then the single shift is 1.5 hours long.
Given that Paolo helped in the community garden for 2 +3/4 hours this week which is 1+5/6 times length shift.
We are required to find the length of a single shift.
First we have to find the proper fraction of the given mixed fractions.
Fraction is combination of numerator and denominator.The number that is present above the division sign is known as numerator and the number that is present below the division sign is known as denominator.
2+3/4=(8+3)/4=11/4
1+5/6=(6+5)/6=11/6
let the length of a shift is x hours.So,
11/4=11*x/6
11/4=11/6 x
66/44=x
x=3/2
x=1.5 hours.
Hence if 2+3/4 hours is equal to 1+5/5 equal length shift then the single shift is 1.5 hours long.

The quartiles of the data are: 60.5,64,66
Option(b) is correct.
The quartile divides the distribution into four groups and calculates the range of values above and below the mean.
A quartile separates the dataset into four categories by dividing the data into three points: the lowest, median, and upper quartiles.
Similar to how the median divides the data in half, with 50% of the measurements falling below it and 50% falling above it, the quartile divides the data into fourths, with 25% of the measurements falling below the lower quartile, 50% falling below the median, and 75% falling below the upper quartile.
The interquartile range, a measurement of variation around the median, is calculated using quartiles.
For the given data set: 58,60,60,61,62,64,64,64,66,70,72

16) 3x - 14 = 34
3x = 48 Add 14 to each side (to isolate 3x)
x = 16 Divide by 3 both sides (to get x)
17) -4(x+3) = -28
x+3 = 7 divide by -4 on both sides (to get a step closer to solving for x and isolating x+3)
x = 4 subtract 3 from both sides (to get x (isolating x))
18) 43 - 9(x-7) = -x - 6
43 - 9x + 63 = -x - 6 distribute 9 to x and 7 (to expand)
106 - 9x = -x - 6 combine like terms (easier to deal with)
106 - 8x = -6 add x to both sides (so there's only x on one side)
112 - 8x = 0 add 6 to both sides (only one number left)
112 = 8x move -8x to the right side
x = 14 divide by 8 (to isolate x)

x = 4
XY = 3(4) - 5 = 12 - 5 = 7

9) 3.8*4 = 15.2 yd
3.8^2 = 14.44 yd^2
19) 34 + 4x + 30 = 180

The lower-priced speaker docks and higher-priced speaker docks is 9 and 36 respectively.
AlgebraCost of higher-priced speaker = $170Cost of lower-priced speaker = $80Number of lower-priced speaker = 4xNumber of higher-priced speaker = xHigher-priced speaker = 170 × x
= 170x
Lower-priced speaker = 80 × 4x

Total sales = $4,410
170x + 320x = 4,410
490x = 4,410
divide both sides by 490
x = 4,410 / 490
x = 9
So,
Number of lower-priced speaker = 4x

The responses were normally distributed, with a mean of 5.2 and a standard deviation of 2.5. Answer parts (a)–(d) below.
The probability that a randomly selected study's participant was less than 4 is 0.2266.
How to compute the probability?Given that:
mean = 5.8
standard deviation = 2.4
a) P(x < 4) = P[(x - mean ) /sd < (4 - 5.8) / 2.4]
= P(z < -0.75)
Using z table,
= 0.2266
b) P(4 < x < 6) = P[(4 - 5.8)/ 2.4) < (x - \m ) /sd < (6 - 5.8) / 2.4) ]
= P(-0.75 < z < 0.08)
= P(z < 0.08) - P(z < -0.75 )
Using z table,

About 5% of the population has a particular genetic mutation. 300 people are randomly selected.
Find the standard deviation for the number of people with the genetic mutation in such groups of 300. Round your answer to two decimal places.
The standard deviation for the number of people with the genetic mutation is 3.77
How to determine the standard deviation?The given parameters are:
Sample size, n = 300
Proportion that has the particular genetic mutation, p = 5%
The standard deviation for the number of people with the genetic mutation is calculated as:
Standard deviation = √np(1 - p)
Substitute the known values in the above equation
Standard deviation = √300 * 5% * (1 - 5%)
Evaluate the product
Standard deviation = √14.25
Evaluate the exponent
Standard deviation = 3.77
