Answer:
The angels are 60 degrees and 120 degrees
Step-by-step explanation:
The sum of two supplementary angels equal 180 degrees.
So, lets look at the ratio: 6:3
We then add 6 and 3 together which gives us 9.
Then you put it in this equation:
9x = 180
x= 20
- You are adding the two numbers and dividing the sum by 180 because the answer will tell us how much 1 would equal.
- In this case, we multiply 20 by 6 = 120 degrees
- Then we multiply 20 by 3 = 60 degrees.
(We can check our answer by: 120 + 60 = 180 degrees) :)
A plane travels a distance of 21,000 kn in a time of 3.2 hours what is its average speed rounded to the nearest whole number
Answer:
6563kmph
Step-by-step explanation:
take 21,000 divided by 3.2 hours to get the speed
21,000/3.2 = 6562.5
It says to round 6562.5 to the nearest whole number so its 6563

3. Mrs. Sinclair is finding the selling price of a pair of $40
skates with a 30% markup. Find her mistakes and correct it.
Answer:
Selling price : $52
Step-by-step explanation:
First, find 30% out of 40.
x= (40)(30)=1200/ 100= 12
x=12
Add 30% to the original selling price.
So then you add $12 to $40 to get $52.
Write 10x² + 3x -2=-1 in the form a(x+h)²+k clearly stating
the turning point or vertex.
Y intercept
The roots of the equation
Answer:
Below in bold.
Step-by-step explanation:
10x² + 3x -2 = -1
10x^2 + 3x - 1 = 0 Taking 10 out from the first 2 terms:-
10(x^2 + 0.3) - 1 = 0 Completing the square:
10[(x + 0.15)^2 - 0.15^2] - 1 = 0
10[(x + 0.15)^2 - 0.0225] - 1 = 0
10(x + 0.15)^2 - 0.225 - 1 = 0
10(x + 0.15)^2 - 1.225 = 0 is vertex form.
The vertex (turning point is at (-0.15, -1.225).
y- intercept is at the point where x = 0,
- that is at y = 10(0.15)^2 - 1.225 = -1
So at (0, -1).
Solving for x:
10(x + 0.15)^2 - 1.225 = 0
(x + 0.15)^2 = 0.1225
x + 0.15 = +/- sqrt 0.1225
x = -0.15 +/- sqrt 0.1225
The roots are -0.5, 0.2
Examine the quadratic equation 9x^2+12x +4= 0.
A: What is the discriminant of the quadratic equation?
B: Based on the discriminant, how many roots does the equation have?
C: State whether the root(s) are real or complex.
Answer:
See answers and explanations
Step-by-step explanation:
A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0
B) Since the discriminant is 0, this means the equation only has one root.
C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)
How to solve for P in a compound interest formula?
Calculation. Formula.
P (1 + r/n)^(nt)
Calculate accrued amount. Principal + Interest. A = P(1 + r)t

Calculate principal amount. Solve for P in terms of I. ...
Calculate rate of interest. As a decimal. ...
Calculate rate of interest. As a percent. ...
Calculate time. Solve for t.
The solution for P (Principal amount) in a compound interest Formula is; P = A/(1+ r)^t.
Changing the Subject of a formulaBy convention, the formula for calculating the compound interest is;
A = P(1 + r)^tOn this note, it follows that; the principal amount, P can be calculated by dividing both sides of the equation by the expression; (1+ r)^t.
Ultimately, the solution for P is; P = A/(1+ r)^t.

Step-by-step explanation:
we can use point-slope form to find this answer.
first, make this equation
y-y 1=m(x-x1)
y-4=-6(x-1)
m=-6 because you can use slope intercept form to find the slope (as the name states lol)
then just distribute!!
y-4=-6x+6
add four to both sides
y=-6x+10

Olivia used colored ribbon for a craft project. She used 1/6 of a yard of green, 1/3of a yard of red, and 1/4 of a yard of yellow. Which ribbon is the longest? *
Answer: Red ribbon.
Step-by-step explanation:
When it comes to fractions, if all the fractions being compared have the same numerator, the fraction with the smallest denominator is the largest.
In this question, all the fractions have a numerator of 1 so the longest one will be the one with the smallest denominator which is 1/3. The red ribbon is the longest.
Another way is to convert them to percentages:
1/6 * 100% = 16.7%
1/3 * 100% = 33.3%
1/4 * 100% = 25%
Red ribbon is again the largest.

In order to acquire the information directly from the users which cannot be measured otherwise, surveys are the best option. These provide an appropriate way of reaching out to large masses at a small-time with little or no prior investment.
A 3 digit number is such that twice the hundreds digit is more than the tens digit by 2.The digit is thrice the hundreds digit.When the digits are reversed, the number is increased by 594.Find the number.
Answer:
The number is -341
Step-by-step explanation:
Let the three digit number be represented as 100a+10b+c
Given
2a -b = 2 ---(1)
a = 3c ----(2)
100a+10b+c - 100c -10b -a = 594
99a -99c = 594 ---(3)
From 2 & 3 , we get -
99*a - (99*3*a) = 594
99*2 a = 594
a = -3
a = 3c, c = -1
2*-3 -b = 2, b = -4
Number is -341
