[tex] {x}^{2} = 6 \times (6 + 18) \\ {x}^{2} = 6 \times 24 \\ {x}^{2} = 144 \\ x = \sqrt{144} \\ x = 12 \\ [/tex]
What is the value of y?
40°
Y + 30°
Answer:
y = 55
Step-by-step explanation:
The sum of the angles of a triangle are 180
40 + y+30 + y = 180
Combine like terms
70 +2y = 180
Subtract 70 from each side
2y = 180-70
2y = 110
Divide each side by 2
2y/2 = 110/2
y = 55

any number that divisible by 3 is also divisible by 6 . Find a counterexample to show that the conjecture is false
Answer:
Counterexample: 21 which is divisible by 3 but not by 6.
Step-by-step explanation:
Use for example the number 21 which is divisible by 3 rendering 7, but not divisible by 6.
You can find any number with at least a factor of "3", but no factor "2" in it, so any odd number divisible by 3 would work as counterexample.

The recipe calls for a pound and a half of strawberries, but I only needed one-third as many blueberries as I did strawberries to make the pie. How many blueberries did I need?
Answer:
8 ounces
Step-by-step explanation:
First, you should convert the 1 1/2 pounds to ounces. (24 ounces) Once that is converted, you can then divide it by 3 to find how many blueberries you need. (24÷3=8) So now you can see that you need 8 ounces of blueberries for the pie.
Line p and q are parallel lines. The slope of line q is-3. Determine the slope of line p. Type a numerical answer in the
space provided. If necessary, use the key to represent a fraction bar. Do not put spaces in your answer.
Answer:
The slope of p is also - 3 .
Since p and q are parallel their slope are also the same.
Hope this helps
Answer:
The slope of line p is also -3
Step-by-step explanation:
Recall that parallel lines have the property of carrying the exact same slope (that is why they don't intersect). Therefore if the slope of line q is -3, the slope of line p must also be -3.

A windshield wiper blade is 18 inches long. To the nearest square
inch, what is the area covered by the blade as it rotates through an
angle of 122 degrees? (Enter just a number for your answer.)
the answer is 22 degrees
The area covered by the blade as it rotates through an angle of 122 degrees is approximately 346 square inches.
We have,
The area of a sector can be calculated using the formula:
Area = (θ/360) * π * r²
where θ is the central angle in degrees, π is a mathematical constant approximately equal to 3.14159, and r is the radius of the sector.
The central angle is 122 degrees, and the radius of the wiper blade is 18 inches.
Substituting the values into the formula:
Area = (122/360) * π * (18²)
Area = (0.3389) * 3.14159 * 324
Area ≈ 344.77 square inches
Area = 345 square inches
Therefore,
The area covered by the blade as it rotates through an angle of 122 degrees is approximately 346 square inches.

The amount of time (t) in minutes it takes to make a coffee at Starbucks is related to (n) the number of coffees they purchase. The equation is t= 21-3 How long does it
take if a customer buys 5 coffees?
Answer: 7 minutes
Step-by-step explanation:
There is no n variable in the question, found the original question and the equations is: t = 2n – 3.
So, to answer this question we simply have to substitute n=5 in the equation given:
t = 2(5) – 3.
Solving for t(time)
t = 10-3 = 7 min.
It will take the customer 7 minutes to buy 5 coffees.

A band went to a recording studio and recorded 4 songs in 3 hours. How many hours would it take the band to record 9 songs if they record at the same rate?
Answer:
6 hours and 45 minutes
Step-by-step explanation:
if you divide 3 hours by four songs you deduce that it take 45 minutes to record one song.
8 is double 4 so it will take 3more hours plus the 45 minutes for the ninth song.

b. tan^2 θ⋅cos^2 θ=sin^2 θ
c.tan^2 θ⋅cos^2 θ=1−sin^2 θ
d.tan^2 θ=1−cos^2 θ⋅cos^2 θ
Answer:
1. From sin²θ +cos²θ =1 and sinθ=-2/3, we see that cosθ=√(1-sin²θ) or cosθ=√5/3, where the sign of cosine is positive as it is in Quadrant IV. x lies in 4th quadrant , cos x is +ve. , cos x = √5/3. Answer.
answer : cos x = √5/3
2. 4/3
3. sin (- theta) = - sin (x) so sin x = 1/6
tan = sin / cos = 1/6 / cos = - sqrt35/35 solve for cos
cos = 1/6 * (-35/sqrt35)
= -35 sqrt35 /210
answer : −35/√210
4. The cosine function is an even function, so cos(θ) = cos(-θ).
The relationship between sin(θ) and cos(θ) is sin(θ) = ±√(1 -cos(θ)^2)
For sin(θ) < 0 and cos(θ) = (√3)/4, sin(θ) = -√(1 -3/16) = -√(13/16)
sin(θ) = -(√13)/4 For sin(θ) < 0 and cos(0) = √(3/4), ...
sin(θ) = -√(1 -3/4) = -√(1/4) sin(θ) = -1/2
answer : -13/√4

A graph has average temperature (degrees Fahrenheit) on the x-axis, from 0 to 60, and total coat sales on the y-axis, from 0 to 100. A trend line goes through points (55, 50) and (65, 40).
Quincy claims that if 80 coats are sold, the outside temperature is likely to be about 42°F. Did Quincy make a reliable prediction? If not, what was his mistake?
A.Yes. Quincy’s prediction is reliable.
B.No. Quincy should have used the trend line to find the corresponding y value when x=80.
C.No. Quincy should have used the trend line to find the corresponding x value when y=80.
D.No. The prediction is extrapolated, so it is too far off the graph to be reliable.

Answer:

Step-by-step explanation:
Since f(x) and g(x) share the same top at (0,0), their difference is only a scale factor, so g(x) = ax² but we need to find a.
To find it, we use the given point of g, (2,1)
So g(2) = 1

Instructions: Find the measure of one interior angle for the following regular polygon.
Answer:
60
Step-by-step explanation:
interior angles for a triangle is 180°
180 ÷ 3 sides = 60°
The given regular polygon is an equilateral triangle.
The measure of one interior angle of it is 60°.
The measure of one exterior angle is 120°.
What are the measures of interior and exterior angle of a regular polygon?For an n-sided polygon,
The sum of all interior angles = (n - 2)180°.
The sum of all exterior angles = 360°.
We know, that a regular polygon has all sides equal, all interior angles equal, and also all exterior angles equal.
Therefore,
The value of each interior angle of a regular polygon = (The sum of all interior angles)/n,
or, The value of each interior angle of a regular polygon = {(n - 2)180°}/n.
The value of each exterior angle of a regular polygon = (The sum of all exterior angles)/n,
or, The value of each exterior angle of a regular polygon = 360°/n.
How to solve the question?In the question, we are asked to find the measure of one interior and one exterior angle of the given regular polygon.
The given regular polygon is a three-sided regular polygon, that is, it is an equilateral triangle.
∴ We can say that n = 3.
∴ The value of each interior angle of a regular polygon = {(n - 2)180°}/n.
or, The value of each interior angle of a regular polygon = {(3 - 2)180°}/3 = 180°/3 = 60°.
∴ The value of each exterior angle of a regular polygon = 360°/n.
or, The value of each exterior angle of a regular polygon = 360°/3 = 120°.
∴ The given regular polygon is an equilateral triangle.
The measure of one interior angle of it is 60°.
The measure of one exterior angle is 120°.

Answer:
Correct option: C) 90 degrees
Step-by-step explanation:
When we have a tangent segment to a circle, the angle made with the radius of the circle and the tangent segment is always a right angle, that is, 90 degrees. In other words, the radius and the tangent segment are always perpendicular.
If QR is tangent to the circle P, and PQ is the radius of the circle, the segment PQ is perpendicular to the segment QR, so the angle PQR is equal 90 degrees.
Correct option: C)

Angle PQR is 90 so answer would be C

Answer:
Brainliest please
Step-by-step explanation:
perimeter is to add all sides
73m= 16+B+C
{ use algebra}
C is a, B is twice C, hence 2a
a+2a(+16)=73
3a=73-16= 57
3a=57, divide
a= 19
B=19×2= 38m
C=19m
C is 19m
Answer:
C = 19 m
Step-by-step explanation:
Side B is twice the length of Side C.
B = 2C -----------(I)
Perimeter = 73 m
A + B + C = 73
A + 2C + C = 73 {from (I)}
16 + 3C = 73

Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplifying
[tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex]
