Answer:
degrees ⋅(π radians /180 degrees )
the (π180) means that for every π radians you go around the unit circle, you've gone 180 degrees.
315 degrees ⋅(π radians /180 degrees )
315 and 180 are both divisible by 45 , so.
74⋅π radians = 74π radians.
Find the solution set.
(x - 5)(x-5) = 0
Answer:
x = 5
Step-by-step explanation:
Steps to solve:
(x - 5)(x - 5) = 0
~Set both factors to equal 0
x - 5 = 0
x - 5 = 0
~Solve for x
x - 5 = 0
x - 5 + 5 = 0 + 5
x = 5
We only solved for one factor since they are both the same and the x value for both are also the same.
Best of Luck!

What is the measure of angle C?
Please Help!!!
Answer:
C=62 maybe
Step-by-step explanation:
3x=x+20
-x -x
2x=20
divide by 2
x=10
2*10=20+38=58
10+20=30
3*10=30
30+30=60+58=118
180-118=62

Fair Spinner A has four equal sections labelled 1,2,3,4.
Fair Spinner B has four equal sections labelled 2,3,4,5.
Each Spinner is spun once and the numbers added.
Work out the probability that the total is 5 or less.
Give your answer as a Fraction.
Answer:
3/8
Step-by-step explanation:
The spinner A has 4 possible values:
1, 2, 3, 4
The spinner B has 4 possible values:
2, 3, 4, 5
The possible pairs we can have are:
(1,2), (1,3), (1,4), (1,5),
(2,2), (2,3), (2,4), (2,5),
(3,2), (3,3), (3,4), (3,5),
(4,2), (4,3), (4,4), (4,5).
The sum of these pair of values are:
3, 4, 5, 6,
4, 5, 6, 7,
5, 6, 7, 8,
6, 7, 8, 9.
So we have 6 values that are 5 or less, in a total of 16 values, so the probability of the sum being 5 or less is P = 6/16 = 3/8
Complete the square to rewrite x^2+y^2+2x+6y-6=0 in graphing form
Answer:
(x + 1)² + (y + 3)² = 16
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + y² + 2x + 6y - 6 = 0
Collect the x and y terms together and add 6 to both sides
x² + 2x + y² + 6y = 6
To complete the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(1)x + 1 + y² + 2(3)y + 9 = 6 + 1 + 9
(x + 1)² + (y + 3)² = 16
with centre = (- 1, - 3) and r = [tex]\sqrt{16}[/tex] = 4
A bird flies from the bottom of a canyon that is 77 1/10 and one tenth feet below sea level to a nest that is 738 3/5 and three fifths feet above sea level. What is the difference in elevation between the bottom of the canyon and the bird's nest?
Answer:
[tex]805\frac{8}{10}[/tex]
Step-by-step explanation:
[tex]805\frac{8}{10}[/tex]
The bottom of the conyon to ses level plus sea level to the bird nest.
First you add 82+723
And than you need to find the common denominator in this case [tex]10\frac{1}{2} =\frac{5}{10}[/tex]
[tex]\frac{5}{10} +\frac{3}{10}[/tex]

Hey, can anyone help me? My math question is: "What sort of information can you get from conditional frequencies that you couldn't get by just looking at the relative frequencies?"
Thanks :)
Answer: Conditional frequencies enables users to get more specific information when analyzing a dataset.
Step-by-step explanation: Frequency refers to the count of occurrence of a particular variable.
Relative frequency is obtained by taking the ratio of the counts a particular variable and the total counts and of all available variables in the experiment or data.
Conditional Frequency allows us to input additional constraints to our frequency counts, especially in a two-way table. Enabling us to get more specific information by using conditional statements.

Answer: 0.44mm
Step-by-step explanation:
In this problem we are asked for the height of a single playing chip. We know the volume of a cylinder is 25120 mm^3.
V=πr²h
25120=πr²h
The problem also gives the diameter of the case: 40mm.
To find radius, you divide the diameter in half.
d=2r
40=2r
r=20
With the radius, we can add that to the volume equation.
25120=[tex]\pi[/tex](20)^2h
25120=400πh
All we have left is to find the height.
h=25120/(400π)
h≈20mm
Now that we know the height, we can find the height of a single chip. The problem states about 50 chips can fit in a case. To find the height of a single chip, you would divide 20 by 50.
20mm/50 chips=0.4mm/chip.

[tex]3\sqrt[5]{(x+2)^3}+3=27[/tex]
Show all work
Answer:
Step-by-step explanation:
[tex]3\sqrt[5]{(x+2)^{3}}+3=27[/tex]
[tex]3\sqrt[5]{(x+2)^{3}}=27-3[/tex]
[tex]ln 3\sqrt[5]{(x+2)^{3}}= ln 24[/tex]
[tex]ln 3 + ln\sqrt[5]{(x+2)^{3}}= ln 3 + ln 8[/tex]
[tex]ln\sqrt[5]{(x+2)^{3}}= ln 8[/tex]
[tex]\frac{3}{5} ln(x+2)= ln 8[/tex]
[tex]ln(x+2)=\frac{5}{3} ln 8[/tex]
x + 2 = [tex]\sqrt[3]{8^{5}}[/tex]
x = [tex]\sqrt[3]{8^{5}}[/tex] -2
3(5x – 10) < 30x solve for x
Answer:
x>-1.25
Step-by-step explanation:
3(5x-10)<30x
15x-20<30x
-20<15x
-20/15<x
-1.25<x
x>-1.25
Step-by-step explanation:
Step 1: Distribute
[tex]3(5x - 10) < 30x[/tex]
[tex](3 * 5x) + (3 * -10) < 30x[/tex]
[tex]15x - 30 < 30x[/tex]
Step 2: Subtract 15x from both sides
[tex]15x - 15x - 30 < 30x - 15x[/tex]
[tex]-30 < 15x[/tex]
Step 3: Divide both sides by 15
[tex]-30 / 15 < 15x / 15[/tex]
[tex]-2 < x[/tex]
Answer: [tex]x > -2[/tex]

<>) Melinda
Melinda says that 500 divided by 50 is 10. Use the drop-down menus to explain
why Melinda's statement is true.
Click the arrows to choose an answer from each menu.
The value of a Choose... " in the hundreds place is Choose...
of a 5 in the Choose... place.
times the value
Answer:
The statement "500 divided by 50 is 10" is a true statement
Step-by-step explanation:
In mathematics, we have a term that we refer to as Place Value.
Place Value in mathematics can be defined as the value that a digit has based on its position or place in a number.
Examples of place value is:
Thousands represented by Th
Hundreds represented by H
Tens represented by T
Units represented by U
In the above question,
500 ÷ 50 gives us 10.
This is true because, 500 as a number, the Digit 5 has a place value of hundreds
50 as a number , the digit 5 has a place values of Tens.
10 as a number, the digit 1 has a place value of Tens.
In mathematics, the multiplication of 2 numbers in a place value of Tens always gives us a place value of hundreds.
For example, 10 × 50 = 500
Likewise, when we divide, a number with a place value of hundreds by a number with a place value of tens, we have a number with a place value of tens.
For example: 500 ÷ 50 = 10.
Therefore, the statement "500 divided by 50 is 10" is a true statement
5. Factor each expression.
a. 15a - 13a
b. -6x – 18y
c. 36abc + 54ad
Step-by-step explanation:
a.)
= 15a - 13a
= a(15 - 13)
= a(2)
= 2a
b.)
= -6x - 18y
= -(x + 3y)
c.)
= 36abc + 54ad
= 6a(6bc + 9d)
Answer:
[tex]a \: ) \: \: 15a - 13a \\ = a(15 - 13) \\ = a(2) \\ = 2a[/tex]
[tex]b) \: \: - 6x - 18y \\ = - 6(x + 3y)[/tex]
[tex]c) \: \: 36abc + 54ad \\ = 9a(4bc + 6d)[/tex]
someone lmk plzzz tyy
Answer:
y-1 = -(x-2)
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= (5-1)/(-2 -2)
= 4/-4
= -1
We are using point slope form using the point (2,1)
y-y1 = m(x-x-1)
y-1 = -1(x-2)
y-1 = -(x-2)
(a + 3)(a - 2) (multiplying polynomials by polynomials is the assignment, i need help lol)
Answer:
a^2 +a -6
Step-by-step explanation:
(a + 3)(a - 2)
FOIL
first: a*a = a^2
outer: -2*a = -2a
inner: 3*a =3a
Last : -2*3 = -6
Add them together
a^2 -2a+3a -6
Combine like terms
a^2 +a -6
Answer:
a² + a - 6
Step-by-step explanation:
(a + 3)(a - 2) = a² - 2a + 3a - 6 = a² + a - 6
Two owners of a cattle ranch, Jo and Val, want to find the average weight for the ranch's 200 cows. Instead of weighing all of the cows: Jo weighs 25 cows and gets an average weight of 1,350 pounds (stdev 50) Val weighs 100 cows and gets an average weight of 1,420 pounds (stdev 50) What is Jo's margin of error, rounded to the nearest whole number? (The formula is )
Answer:
Jo Margin of error is 20
Step-by-step explanation:
The expression for calculating Margin of error is = [tex]Z_{critical } *\dfrac{{Sd} }{\sqrt{n} }[/tex]
From the given question:
[tex]Z_{critical} = 1.96[/tex]
standard deviation sd = 50
sample size = 25
THUS; the Margin of error is :
[tex]1.96*\dfrac{{50} }{\sqrt{25} }[/tex]
[tex]1.96*\dfrac{{50} }{5 }[/tex]
[tex]1.96*10}[/tex]
[tex]19.6[/tex]
≅ 20 (to the nearest whole number)
Hence; Jo Margin of error is 20
.5s+1=7+4.5s solve for s
Answer:
The answer is [tex]s = - \frac{3}{2}[/tex] .
Step-by-step explanation:
Solve the equation:
[tex]0.5s + 1 = 7 + 4.5s[/tex]
-Subtract [tex]4.5s[/tex] from [tex]0.5s[/tex] :
[tex]0.5s + 1 -4.5s = 7 + 4.5s -4.5s[/tex]
[tex]-4s + 1 = 7[/tex]
-Subtract both sides by [tex]1[/tex] :
[tex]-4s + 1 - 1 = 7 -1[/tex]
[tex]-4s = 6[/tex]
-Divide both sides by [tex]-4[/tex] :
[tex]\frac{-4s}{-4} = \frac{6}{-4}[/tex]
[tex]s = -\frac{3}{2}[/tex]
So, therefore, the final answer is [tex]s = -\frac{3}{2}[/tex] .
-9x + 0.4 = 4 hhhhhhhhheeeeeeeeellllllllppppppp
Answer:
x = -0.4
Step-by-step explanation:
First subtract the 0.4 from both sides. Then divide both sides by -9 to solve for x.
Answer:
-0.4
Step-by-step explanation:
Subtract 0.4 from both sides.
-9x + 0.4 = 4
-0.4 -0.4
-9x = 3.6
Divide both sides by -9.
-9x/-9 = 3.6/-9
Simplify
x = -0.4
