Henry loves to play the piano but doesn't like practicing the exercises his piano teacher assigns. Henry knows the exerc
ises will help him play better though, so he tries to
motivate himself using his favorite treat - chocolate chip cookies. There is a proportional relationship between the am
ount of time (in hours) that Henry practices the piano,
x, and how many cookies he gives himself.y.
When Henry practices for 3 hours, he gives himself 9 cookies.
Write the equation for the relationship between x and y.
Answer:
x3=y
Step-by-step explanation:
Write an equation of the perpendicular bisector of the segment with endpoints M(10,-7) and N(-4,1).
Mateo decide pedir un préstamo de 600 soles durante 2 años a un banco el cual le ofrece una tasa de interés anual de 16%calcula al interés simple y el monto total que pagará al término de 2 años
Answer:
192 and 792
Step-by-step explanation:
Given that
The principal is 600 soles
The Time period is 2 years
The Rate of interest is 16%
We need to find out the simple interest and the total amount paid at the end of 2 years
As we know that
SImple interest is
= Principal × rate of interest × time period
= 600 × 16% × 2
= 192
And, the amount is
= Principal + interest
= 600 + 192
= 792
what is the measure of each angle?
help pls!

geometry!!
Answer:
A straight angle is the same as half the circle and is 180° whereas a right angle is a quarter of a circle and is 90°. You measure the size of an angle with a protractor. Or could be shown by an arc on the figure to indicate which angles that are congruent

3. Scout is conducting a research project on traffic patterns
in her town. She realizes that at 6:00 AM each morning, the
traffic lights reset and function on a pattern. The traffic light
on Main St. turns red every 7 minutes. The traffic light on Elm
St. turns red every 15 minutes. At what time will both lights be
red at the same time?
Answer:
7:45
Step-by-step explanation:
Since they both turn red at differnt times, you have to find a multiple to find the time they will be both on
Main St: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105
Elm St. 15, 30, 45, 60, 75, 90, 105
They will both turn on 105 minutes or 1 hour and 45 minutes from 6
6 + 1 hr 45 min = 7:45

Answer:
$2.96
Step-by-step explanation:
1.15x = 3.40 x = last year's price. If there price was exactly the same, I would put 1x, but this year's price is 15% or .15 higher.
1.15x = 3.40 Divide both sides by 1.15 and round to the nearest cent.
x = 2.96
Check:
Last year + 15% (.15)
2.96 + .15(2.96)
2.96 + .44 rounded to the nearest cent
3.40

The measure of minor arc JL is 60°.
Circle M is shown. Line segments M J and M L are radii. Tangents J K and L K intersect at point K outside of the circle. Arc J L is 60 degrees.
What is the measure of angle JKL?
Answer:
m∠JKL = 120°
Step-by-step explanation:
The measure of an angle formed by a two tangents drawn from a point outside the circle is the the difference of the intercepted arcs
minor arc JL = 60 major arc JL = 360 - 60 = 300
m∠JKL = 1/2(300 - 60) = 1/2(240) = 120

PLEASE HELP, ILL GIVE BRAINLIEST!!
Answer:
as mentioned above we have to solve it by cross multiplication.
Step-by-step explanation:
So,
4(3x-3)=5(2x-2)
12x-12=10x-10
12x-10x=-10+12
2x=2
X=2/2=1 Answer
hope it helps!!
Answer:
x = 1
Step-by-step explanation:
Here's your solution
=> (3x - 3)/5 = (2x - 2)/4
=> 4(3x -3) = 5(2x - 2)
=> 12x - 12 = 10x - 10
=> 2x = 2
=> x = 2/2
=> x = 1

Answer:
2410.26
Step-by-step explanation:
This is a bit complicated but, you have to take 3.5% of 2,250 (2,250*0.035=78.75). Then add 78.75 to the total (2,250) (2328.75 new total). Next take 3.5% of the new total and repeat that process and you end up with 241.26.

Answer:
i) p = 4
ii) p = 8
iii) p = 12
Step-by-step explanation:
Here, we need to understand the initial relation
Mathematically, we have this as;
2.79 * p = c
So let us calculate the value of p for each value of c
i) 2.79p = 11.16
p = 11.16/2.79
p = 4
ii) 2.79p = 22.32
p = 22.32/2.79
p = 8
iii) 2.79p = 33.48
p = 33.48/2.79 = 12
Solve for x and found your answer to the nearest tenth.
Answer:
11.1
Step-by-step explanation:
To find the side measurement we have to use trig, and the trig function Cosine, or cos. We use the because cosθ=[tex]\frac{adjecent}{hypotenuse}[/tex]. So cosθ=[tex]\frac{x}{15}[/tex], then to isolate x multiply both sides by 15. Now we have 15cos42=x, plugging this into the equation we get that x=11.1

. Complete each equation with a number so that the equation has the stated solution(s). a) x^2+7=x^2+_____; no solution
Answer: other than 7
Step-by-step explanation:
Given
Equation is [tex]x^2+7=x^2+?[/tex]
For an equation to have no solution, the missing number can be any number other than 7
because if we put 7 then it justifies the equation i.e. [tex]7=7[/tex] while on the other hand for a number other than 7, it does not justify the equation.
