Find the radius of the circle. Please show work, thank you
Answer:
4.8
Step-by-step explanation:
The length of an arc is 18cm and the radius of the circle is 6cm. What is the radian
measure of the central angle?
Answer:
3
Step-by-step explanation:
Radian= arc/radius
18/6=3
The Central angle was calculated to be 3 radians using the formula.
what is a central angle?it is the angle subtended by radii and corresponding arc.
as we know that
length of an arc= central angle* radius
so, central angle = arc length/radius
it is given that
length of the arc=18cm
the radius of the circle=6cm
central angle= 18/6 = 3 radian.
therefore, the central angle was calculated to be 3 radians using the formula.

Express as a trinomial **brainliest**
(2x+5)(3x−4)
Answer:
[tex]\boxed {\boxed {\sf 6x^2+7x-20}}}[/tex]
Step-by-step explanation:
We are given 2 binomials (meaning they have 2 terms) and asked to express as a trinomial.
To do this, we have to multiply the 2 binomials using the FOIL method. FOIL stands for first, outside, inside, and last. Basically, multiply the first terms from both, then the outside, and so on.
F : First
[tex](\underline{2x}+5)(\underline{3x}-4)[/tex]
2x * 3x= 6x²
O: Outside
[tex](\underline{2x}+5)(3x \underline {-4})[/tex]
2x * -4 = -8x
I: Inside
[tex](2x+\underline5)(\underline{3x}-4)[/tex]
5 *3x=15x
L: Last
[tex](2x+\underline5)(3x\underline{-4})[/tex]
5*-4= -20
Now, put all the products together into one expression.
[tex]6x^2-8x+15x-20[/tex]
However, this is not a trinomial yet. There are like terms that can be combined. Notice how 2 terms both have the variable x. They can be added together.
[tex]6x^2 + (-8x+15x)-20[/tex]
[tex]6x^2+7x-20[/tex]
Now there are 3 terms and we have a trinomial: 6x²+7x-20
what is the equation of the line if its slope is -3/4 and Y-intercept is -4
Answer:
[tex]y=-\frac{3}{4} x-4[/tex]
Step-by-step explanation:
When writing an equation of a line using slope-intercept form: y=mx+b, the slope of the line would take the place of m, and the y-intercept would take the place of b. Just substitute these variables for the slope and y-intercept to find the equation of the line.
lmk if this is incorrect, hope it helps!!
Answer:
y= -3/4x-4
Step-by-step explanation:
This is assuming that you want it in slope-intercept (y=mx+b)
You need to know that
Y= The line
m=Slope
b=y-intercept
Step 1, Replace slope (m)
y= -3/4x+b
Step 2, Replace the y-intercept
y= -3/4x-4
Conclusion to 'what is the equation of the line if its slope is -3/4 and Y-intercept is -4': y= -3/4x-4

A jar contains "q" quarters and "d" dimes. There are 7 coins in the jar and the total value of the coins is $1.00
Which system of equations can be used to find how many of each type of coin is in the jar.
A. 0.25q + 0.10d = 1.00
q + d =7
B. 0.25q + 0.10d= 7.00
q + d = 1
C. 0.10q + 0.25d = 1.00
q + d = 7
D. 25q + 10d = 1
q + d = 7
Answer:
A. 0.25q + 0.10d = 1.00
q + d =7
Step-by-step explanation: Only logical choice I see. The others mix up values and units.
The system of equations is
0.25q + 0.10d = 1.00
q + d =7
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
A jar contains "q" quarters and "d" dimes.
There are 7 coins in the jar and the total value of the coins is $1.00.
As, 2 quarters and 5 dimes
= 2(.25) + 5(.10)
= $.50+ $.50
= $1
Now, according to question,
0.25q + 0.10d = 1
and, 0.10q + 0.10d = 0.7
Solving above equation we get
0.15q = 0.3
q = 2 quarter
Then, d= 7 -q = 7- 2 = 5 quarter

Find the equation of a parabola with focus F(-3, 9) and directrix x = -13.
Answer:
y² = 38x + 79
Step-by-step explanation:
Since directrix is the line x = -13, then it means x + 13 = 0
Focus is F(-3, 9).
Let A(x, y) be any point inside the plane having the focus and directrix.
Let MA be the perpendicular distance from A to the directrix and it means that A lies on parabola provided FA = MA.
Thus;
√[(x - (-3))² + (y - 9)²] = (x + 13)
Squaring both sides gives;
(x + 3)² + (y - 9)² = (x + 13)²
>> (x² + 6x + 9) + (y² - 18x + 81) = x² + 26x + 169
>> 6x + 9 + y² - 18x + 81 = 26x + 169
>> y² = 26x + 12x + 169 - 90
>> y² = 38x + 79

A car dealership offers customers two pricing options for vehicle repair. Option 1: pay $80 per hour of wok. Option 2: pay a standard fee of $100 plus $400 per hour of work. What is the initial value and the rate of change for option 1
Answer:
1: The initial value for option one is not charged
The rate of change for option 1 is $80/hr
Step-by-step explanation:
1. From the pricing options at the car dealership we have;
Option 1
Initial value = Not stated
Fee rate per hour of work = $80
Option 2
Standard fee = $100
Fee rate per hour of work = $400
The initial value for option one is not charged
The rate of change = The increase in payment for each increase in one hour of work = $80/hour
Mathematically, we have;
[tex]The \ rate \ of \ change = \dfrac{\Delta Payment}{\Delta Time} = \dfrac{\$80 - \$0}{1 \, h- 0 \, h} = \$ 80/hr[/tex]
10 students are competing in a dance competition. How many was can you award first, second, and third place?
Given:
Total number of students = 10
To find:
How many was can you award first, second, and third place?
Solution:
Total number of students is 10. So, the total possible ways for the first award is 10.
We know that one student can hold only one place. So, after giving the first award, the number of remaining students is 9 and the total possible ways for the second award is 9.
Similarly, the total possible ways for the third award is 8.
Now, the total number of ways to award first, second, and third place is:
[tex]10\times 9\times 8=720[/tex]
Therefore, the total number of ways to award first, second, and third place is 720.
The amount of time Mary spends on the phone each month can be thought of as a random variable that is approximately normally distributed. Mary spends an average of 40 hours on her phone with a standard deviation of 4 hours. Find the probability that Mary spends between 30 and 40 hours on the phone.
Answer:
0.4938
Step-by-step explanation:
Given that:
Mean, m = 40
Standard deviation, s = 4
Probability of spending between 30and 40 hours on phone :
Zscore = (x - mean) / standard deviation
P(Z = 40) - P(Z= 30)
((40 - 40) / 4) - ((30-40) / 4)
(0/ 4) - (-10/ 4)
P(Z < 0) - P(Z <-2.5)
P(Z^ 0).=0.5 ; P(Z < - 2.5) = 0.0062097
0.5 - 0.0062097
P = 0.4938

Write the equation for the word problem and solve. You bought a magazine for $5 and four erasers. You spent a total of $25. How much did each eraser cost?
Answer: each eraser cost 5 dollors
Step-by-step explanation: Simplifying
25 = 5 + 4e
Solving
25 = 5 + 4e
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-4e' to each side of the equation.
25 + -4e = 5 + 4e + -4e
Combine like terms: 4e + -4e = 0
25 + -4e = 5 + 0
25 + -4e = 5
Add '-25' to each side of the equation.
25 + -25 + -4e = 5 + -25
Combine like terms: 25 + -25 = 0
0 + -4e = 5 + -25
-4e = 5 + -25
Combine like terms: 5 + -25 = -20
-4e = -20
Divide each side by '-4'.
e = 5
Simplifying
e = 5

Answer:
144, 36
Step-by-step explanation:
you know that if you add the two angles it will equal 180 degrees. so add the two angles and make them equal to 180 and solve for x.
(4x+8) + (x+2)=180
5x+10=180
5x=180-10
5x=170
x=34
now replace x in each equation:
4(34)+8=144
34+2=36

Which value from the set { 1/2 , 2/3 , 4/3 , 5/2 } is a value of x that will make the equation 3/4 ÷ x = 9/8 true?
Answer:
2/3
Step-by-step explanation:
To find out what x is in this case, divide 3/4 by 9/8.
3/4 / 9/8
Dividing by a fraction is the same as multiplying it's inverse.
3/4 * 8/9
Cross cancellation (3 & 9 (GCF: 3); 4 & 8 (GCF: 4)
1/1 * 2/3
We can remove the 1/1.
2/3
2/3 is the value of x that will make 3/4 ÷ x = 9/8 true.
