Answer:
133.33%
Step-by-step explanation:
x/y * k = 1.6x / 1.2y
k = (1.6x / 1.2y) / (x/y)
k = 1.6/1.2
k = 4/3 = 1.3333 = 133.33%
A particle is moving with acceleration a ( t ) = 18 t + 16 . Its position at time t = 0 is s ( 0 ) = 10 and its velocity at time t = 0 is v ( 0 ) = 16 . What is its position at time t = 8 ?
Answer:
[tex]s(8)=2186[/tex]
Step-by-step explanation:
A particle is moving with acceleration modeled by the function:
[tex]a(t)=18t+16[/tex]
We are given that its position s(t) at t = 0 is 10 and that its velocity v(t) at t = 0 is 16.
And we want to find its position at t = 8.
Velocity is the integral of the acceleration. Hence:
[tex]\displaystyle v(t)=\int a(t)\, dt=\int 18t+16\, dt[/tex]
Find the velocity. Remember the constant of integration!
[tex]v(t)=9t^2+16t+C[/tex]
Since v(t) is 16 when t = 0:
[tex](16)=9(0)^2+16(0)+C\Rightarrow C=16[/tex]
Hence, our velocity is given by:
[tex]v(t)=9t^2+16t+16[/tex]
Position is the integral of the velocity. Hence:
[tex]\displaystyle s(t)=\int v(t)\, dt=\int 9t^2+16t+16\, dt[/tex]
Integrate:
[tex]\displaystyle s(t)=3t^3+8t^2+16t+C[/tex]
s(t) is 10 when t = 10. Hence:
[tex]C=10[/tex]
So, our position function is:
[tex]s(t)=3t^3+8t^2+16t+10[/tex]
The position at t = 8 will be:
[tex]s(8)=3(8)^3+8(8)^2+16(8)+10=2186[/tex]
A truck is traveling at a constant speed. The diagram represents the truck's distance and time. What is the speed of the truck?
Answer:
distance divided by time
Step-by-step explanation:
distance is the speed of the moving object multiplied by the time taken to complete a certain distance therefore the speed is the distance covered divided by the time taken.

!!!REMEMBER TO GIVE BRAINLIEST IF THIS HELPED!!!Which greatest digit should replace n so that the number 342n84 is divisible by 3?
Answer:
9
Step-by-step explanation:
If you want the number to be divisible by three make sure the sum of all the numbers are divisible by three. Add all the numbers you have to see what they make.
3+4+2+8+4=21
So we just need to find the greatest number we can add to that to have it remain divisible by three. A number divisible by three is 30, and we can add 9 to 21 to make 30. Of course, there are other numbers we could add, but nine is the largest one-digit number that would work. Other smaller numbers include 3 and 6.
3+4+2+8+4+9=30
Now we check to see if our number is divisible by three
342984÷3 = 114328
114328 is a whole number so we know it's divisible.

The measure of L in triangle LMN is 38°. The measure of M is 80°. What is the measure of N? A. 62° B. 42° C. 118° D. 242°
Answer:
62
Step-by-step explanation:
The sum of the angles in a triangle add to 180
L + M + N= 180
38+ 80 + N = 180
118+ N = 180
N = 180-118
N = 62

Samuel says that 25% is greater than 0.3.
Is he correct?
Answer:
No
Step-by-step explanation:
25% as a decimal is 0.25
and 0.3 as a percentage is 30%
Answer:
Samuel is wrong.
Step-by-step explanation:
[tex]25 \% = \frac{25}{100} = 0.25[/tex]
[tex]0.3 = 0.30 = \frac{30}{100} = 30 \%[/tex]

Sarah completes 1/6 of a project in 1/4 of an hour at this rate how much of the project does Sarah complete per hour? Sarah completes blank of the project per hour.
Answer:
2/3
Step-by-step explanation:
Time it would take Sarah to complete the work in one hour = work completed in 1/4 hours x 4
We are multiplying by 4 because there are 4, 1/4 in an hour
1/4 + 1/4 + 1/4 + 1/4 = 1 hour
[tex]\frac{1}{6}[/tex] × 4 = [tex]\frac{4}{6}[/tex]

Pablo drove 715 miles in 11 hours.
At the same rate, how many miles would he drive in 9 hours?
Answer:
585 miles
Step-by-step explanation:
divide 715 by 11 so that you can see the mph (miles per hour). Then multiply that number by 9 for the amount of miles he would travel in nine hours
715/11=65
65x9=585

A baseball is thrown with one quarter rotation that takes 1.35 seconds. What is the angular velocity in units of radians per second?
Answer:
[tex]1.16\:\mathrm{rad/s}[/tex]
Step-by-step explanation:
Angular speed is given by [tex]\omega=\frac{\Delta \theta}{\Delta t}[/tex], where [tex]\Delta \theta[/tex] is angle change in radians and [tex]\Delta t[/tex] is elapsed time.
Since the baseball makes one fourth (one quarter) of a rotation in 1.35 seconds, it will take the baseball [tex]4\cdot 1.35=5.4[/tex] seconds to complete on rotation.
One rotation is 360 degrees or [tex]2\pi[/tex] radians. Therefore, the angular speed of the baseball is:
[tex]\omega =\frac{2\pi}{5.4}=1.16355283466\approx \boxed{1.16\:\mathrm{rad/s}}[/tex]

SkippingSkippingAngles A and EAngles B and CAngles D and EAngles A and HAngles A and BAngle AAngle BAngles E and F=====================================
Explanation:
SkippingSkippingCorresponding angles are ones where they are in the same configuration of the 4 corner angle set up. Angles A and E are in the same northwest position. Another pair would be angles B and F in the northeast, and so on. Corresponding angles are congruent when we have parallel lines like this.Vertical angles form when we cross two lines. They are opposite one another and always congruent (regardless if the lines are parallel or not).Alternate interior angles are inside the parallel lines, and they are on alternating sides of the transversal cut. Alternate interior angles are congruent when we have parallel lines like this. Alternate exterior angles are the same idea as number 5, but now we're outside the parallel lines. Alternate exterior angles are congruent when we have parallel lines like this.Adjacent angles can be thought of as two rooms that share the same wall. Specifically, adjacent angles are two angles that share the same segment, line, or ray. The angles must also share the same vertex. In this case, any pair of adjacent angles always adds to 180 (though it won't be true for any random pair of adjacent angles for geometry problems later on).Simply list any angle that looks obtuse, ie any angle that is larger than 90 degrees.List any angle that is smaller than 90 degrees. It can be adjacent to whatever you picked for problem 8, but it could be any other acute angle as well.Refer to problem 7. In this case, adding any two adjacent angles together forms a straight line.
