Natalie practices the flute 4 days per week. She practices 45 hour each day.
How many hours does she practice the flute each week?
Answer:
180 hours per week
Step-by-step explanation:
To find this answer, multiply all of the factors to get your answer
In this scenario, that would be 45x4
When you multiply this out, you get 180 hours
So your answer is 180 hours per week!
(By the way whoever created this problem doesn’t know simple time because there are only 24 hours in a day!)

I need help with problem 19
Answer:
124
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
The formula for calculating the sum of interior angles is:
(n - 2) x 180° (where n is the number of sides)
interior angle of a polygon = sum of interior angles ÷ number of sides
165 = [ (n - 2) x 180° ] ÷ n
Mulitply both sides by n: 165n = (n - 2) x 180°
Expand brackets: 165n = 180n - 360
Add 360 to both sides: 165n + 360 = 180n
Subtract 165n from both sides: 360 = 15n
Divide both sides by 15: 24 = n
Therefore, the number of sides = 24

Sale price = $ 45.50
Sales tax = 6%
Now find sales tax
( 45.50×6 ) ÷ 100 = 2.73
Now this in sales price
45.50 + 2.73 = 48.23

solve the equation 4x + 6 = 4 + 2(2x + 1). Which choice describes the meaning of his result, 6 = 6?
Answer:
the equation is true
Step-by-step explanation:
solve the equation 4x + 6 = 4 + 2(2x + 1). Which choice describes the meaning of his result, 6 = 6?
4x + 6 = 4 + 2(2x + 1)
4x + 6 = 4 + 4x + 2
6 = 4 + 2
6 = 6
the equation is trueAn angle measures 47.4° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation: Let's say you have 2 supplementary angles, x and y
So x + y = 180
if x is 79.6 degrees less than the measure of a supplementary angle, then x = y - 79.6
Putting this into our x + y = 180 equation, we get
(y - 79.6) + y = 180
2y - 79.6 = 180
2y = 180 + 79.6
2y = 259.6
y = 259.6/2 = 129.8 degrees.
so x = 129.8 - 79.6 = 50.2 degrees.
See if it worked. x = 129.8 degrees, y = 50.2 degrees, x + y = 180 so we found the correct two angles!
Please solve. I think u solve for X
Answer:
x=2.1
Step-by-step explanation:
collect like terms 2.4x+5.8x=8.2x
move the terms to the left side and change its sign to -8.2x
move the constant(-3.28) to the right and change its sign to 3.28
equation should now be 9x-8.2x=-1.6+3.28
next you're going to do 9x-8.2x=0.8x
then -1.6+3.28=1.68
divide both sides of the equation by 0.8
x=2.1 is your final answer

Two buses leave a station at the same time and travel in opposite directions. One bus travels 18 mi/h faster than the other. If the two buses are 994 miles apart after 7 hours, what is the rate of each bus
Answer:
The distance each bus travels is given as d=tr where
- d is distance bus travels
- t is a time bus travels
- r is the speed of the bus
:
Distance first bus travels for 4 hours is d1=4r.
Distance other bus travels for 4 hours is d2=4(r+12).
:
The total distance between them is 480 miles and since they go in opposite directions this distance is the sum of distances each bus travels.
:
d1+d2=480
4r+4(r+12)=480
4r+4r+48=480
8r+48=480
8r=432
r=432/8
r=54 mph, this is a speed of the first bus
:
r+12=66 mph, this is the speed of the second bus
Hope this helps you!!!! :D
The equation has a solution of x = 5. What is the value of k? k =.
The value of k is -11.
Given
The equation 3√(x-k)-2=10 has a solution of x = 5.
How to find the value of k?To find the value of k put x = 5 in the equation then solve for the value of k.
Therefore,
The value of k is;
[tex]\rm 3\sqrt{x-k}-2=10[/tex]
Substitute x = 5 in the equation
[tex]\rm 3\sqrt{5-k}-2=10\\\\\rm 3\sqrt{5-k}=10+2\\\\\rm 3\sqrt{5-k}=12\\\\\rm \sqrt{5-k}=\dfrac{12}{3}\\\\ \sqrt{5-k}=4\\\\[/tex]
Squaring on both sides
[tex]\rm \sqrt{5-k}=\dfrac{12}{3}\\\\5-k=16\\\\-k = 16-5\\\\-k=11\\\\k=-11[/tex]
Hence, the value of k is -11.

Let us suppose that one of the fireworks is launched from the top of the building with an initial upward velocity of 150 ft/s and the building has a height of 35 feet. what is the equation for this situation?
Answer:
9.6 seconds
Step-by-step explanation:
The equation for projectile motion in feet is [tex]h(t)=-16t^2+v_0t+h_0[/tex] where [tex]v_0[/tex] is the initial velocity in ft/s and [tex]h_0[/tex] is the initial height in feet.
We are given that the initial upward velocity is [tex]v_0=150ft/sec[/tex] and the initial height is [tex]h_0=35ft[/tex]. Thus, plugging these values into our equation, we get [tex]h(t)=-16t^2+150t+35[/tex] as our equation for the situation.
The firework will land, assuming it doesn't explode, when [tex]h(t)=0[/tex], thus:
[tex]h(t)=-16t^2+150t+35\\\\0=-16t^2+150t+35\\\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\t=\frac{-150\pm\sqrt{150^2-4(-16)(35)}}{2(-16)}\\ \\t=\frac{-150\pm\sqrt{22500+2240}}{-32}\\\\t=\frac{-150\pm\sqrt{24740}}{-32}\\\\t=\frac{-150\pm2\sqrt{6185}}{-32}\\ \\t=\frac{75\pm\sqrt{6185}}{16}\\\\t_1\approx-0.2\\\\t_2\approx9.6[/tex]
Since time can't be negative, then the firework will land after 9.6 seconds, assuming it doesn't explode at the time of landing.
