Answer:
Below
Step-by-step explanation:
The answer would be 90°
We know that every triangle should add up to 180°,
with that we can solve it!
30° + 40° = 70°!
180° - 70° = 90°!
30° + 40° + 90° = 180°
70° + 90° = 180°

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.

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

if p is inversely proportional to the square of q, and p is 9 when q is 5, determine p when q is equal to 3
Answer: tell me if i am wrong
p = 304
Step-by-step explanation:
Given p is inversely proportional to q² then the equation relating them is
p = [tex]\frac{k}{q^{2} }[/tex] ← k is the constant of proportion
To find k use the condition p = 19 when q is 8, then
19 = [tex]\frac{k}{8^{2} }[/tex] =[tex]\frac{k}{64}[/tex] ( multiply both sides by 64 )
k = 1216
p = [tex]\frac{1216}{q^{2} }[/tex] ← equation of proportion
When q = 2, then
p = [tex]\frac{1216}{2^{2} }[/tex]=[tex]\frac{1216}{4}[/tex]=304
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 A. P = A / (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.

Answer:
B
Step-by-step explanation:
A linear function is described by a x term to the power of 1 or even 0. A function when x is to the second power is most usually not a linear function.
In answer A, you have x multiplied against -3x. This will cause an x squared term, so this is not a linear function.
In answer B, you have 1/2 multiplied against x, which is a regular x term subtracted by 2x, causing a regular x term, meaning this function is linear. However, in the small possibility it is not, we will keep going.
In answer C, there is an x squared term so this is not linear.
In answer D, the expression has 1/2x times 2x, which will cause an x squared term.
Thus, the answer is B, which is the only equation without an x squared term.

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

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.

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)
