Answer:
Step-by-step explanation:
This is more physics than math because you need to know the equations for one-dimensional motion to get this done. The equation we need is
[tex]v=v_0+at[/tex] where v is the final velocity, v0 is the initial velocity, a is the acceleration and t is the time in seconds. That means that since our time is given in minutes we have to convert it to seconds. I'm not sure how much importance your teacher gives to significant digits, but if you use them here, the answer you get is way off, so we will disregard them here. 1.5 minutes is 90 seconds. Now that have the time in seconds and the equation we need, we will fill it in accordingly:
[tex]v=2.5\frac{m}{sec} +(6\frac{m}{sec^2})(90sec)[/tex]
Note immediately that the seconds on the time cancels out one of the seconds in the denominator of the acceleration so we're left with m/sec + m/sec which is what we need to add those 2 terms. Multiply 6 by 90 to get 540 m/sec. then add that to 2.5 m/sec to get 542.5 m/sec. That must be really long hill!!!

whao knows what cuphead is?
Answer: i've heard about it but i'm not too much into it
Answer: Cuphead is a classic run and gun action game heavily focused on boss battles. Inspired by cartoons of the 1930s, the visuals and audio are painstakingly created with the same techniques of the era, i.e. traditional hand drawn cel animation, watercolor backgrounds, and original jazz recordings.
Step-by-step explanation:
A 35-foot tall pole is leading towards a building. To stop the pole from leaning
further, a 48-foot long cable is secured from the top of the pole to a stake in the
ground opposite of the building. If the stake is 30 feet from the pole, what angle
does the cable make with the pole?
9514 1404 393
Answer:
38.5°
Step-by-step explanation:
You are given all three side lengths of the relevant triangle, so the Law of Cosines can be used to find any desired angle. If we call the desired angle C, then that law tells you ...
C = arccos((a² +b² -c²)/(2ab))
where a and b are the triangle side lengths adjacent to the angle of interest, and c is the side opposite. Here, 'a' and 'b' are the pole and cable lengths, and 'c' is the distance of the stake from the pole.
C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360)
C ≈ 38.515°
The cable makes an angle of about 38.5° with the pole.

apply the definition of subtraction and properties of operations to find the result (3/8+2/3) - 3/8
Answer:
The result is [tex]\frac{2}{3}[/tex].
Step-by-step explanation:
Since there is no symbol in front of the first bracket, we can straight up remove it with no consequences.
Hence, the equation we get is:
[tex]\frac{3}{8} + \frac{2}{3} - \frac{3}{8}[/tex]
[tex]= \frac{2}{3}[/tex]
Therefore, the result is [tex]\frac{2}{3}[/tex].

Choose whether the expression is a result of multiplying
conjugates together, squaring binomials, or neither.
25c^2 + 55c + 30
-multiplying conjugates
-squaring binomials
-neither
-both
Answer:
neither
Step-by-step explanation:
Take out 5 as a common factor. It will be easier to look at.
5(5c^2 + 11c + 6)
5(5C +6 )(c + 1 )
Now you can put the 5 inside.
(25c + 30)(c + 1) is one answer.
(5c + 6)(5c + 5) is another.
The answer is multiplying binomials. There is nothing that that is squared and the answers are not conjugates. They are two binomials multiplied together.

In the picture lines AB and CD are parallel. Find the measures of the following angles. Explain your reasoning.
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°

An outlet store had monthly sales of $73,000 and spent 8% of it on health insurance.
How much was spent on health insurance?
1. We assume, that the number 73000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 73000 is 100%, so we can write it down as 73000=100%.
4. We know, that x is 8% of the output value, so we can write it down as x=8%.
5. Now we have two simple equations:
1) 73000=100%
2) x=8%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
73000/x=100%/8%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 8% of 73000
73000/x=100/8
(73000/x)*x=(100/8)*x - we multiply both sides of the equation by x
73000=12.5*x - we divide both sides of the equation by (12.5) to get x
73000/12.5=x
5840=x
x=5840
now we have:
8% of 73000=5840
How much was spent on health insurance is $5,840
Using this formula
Amount spent=Monthly Sales× Health insurance percentage
Where:
Monthly Sales =$73,000
Health insurance percentage=8%
Let plug in the formula
Amount spent=$73,000×8%
Amount spent=$5,840
Inconclusion How much was spent on health insurance is $5,840

The height of a model rocket, H(t), is a function of the time since it was launched, t.What is the domain of H(t)?A.0 ≤ t ≤ 324B.0 ≤ t ≤ 36C.t ≤ 324D.t > 0
Answer:
[tex]0 \le t \le 36[/tex]
Step-by-step explanation:
Given
The graph of h(t)
Required
Determine the domain
t represents the horizontal data and according to the graph;
The value of t starts at 0 (the beginning of the curve)
and ends at 36 (the end of the curve)
These values are the domain of the graph, and it can be represented as: [tex]0 \le t \le 36[/tex]
The domain of H(t) is [tex]0\leq t\leq 36[/tex]
The correct answer is option B. 0 ≤ t ≤ 36
To do this question, the main thing is to look at picture.
We know from the graph that this is a quadratic function, So t has to be less than some positive number.
{ if t → -∞, H(t) → -∞, not in the line with the actual situation}
and look at the graph, the point where H(t) equals zero, one is 0 and one is 36.
Therefore: the domain of H(t) is [tex]0\leq t\leq 36[/tex].

Peter says, "If you subtract 17 from my number and multiply the difference by −3, the result is −45." What is Peter's number?
Answer:
32
Step-by-step explanation:
Let Peter's number = p
(Peter's number - 17) * - 3 = - 45
(p - 17) * - 3 = - 45
Open the bracket
-3p + 51 = - 45
-3p = - 45 - 51
-3p = - 96
Divide both sides by -3
-3p/ -3 = - 96/ - 3
p = 32
Hence, Peter's number is 32

Answer:
∠D = 60
∠E = 99; x = 4
x = 32
Step-by-step explanation:
First things first, the sum of angles in a quadrilateral is 360°.
∠D + 120 + 95 + 85 = 360
∠D = 360 - 120 - 95 - 85
∠D = 60
∠E + 86 + 100 + 75 = 360
∠E = 360 - 86 - 100 - 75
∠E = 99
24x + 3 = 99
24x = 99 - 3
= 96
x = 96 ÷ 24
x = 4
89 + 5x - 8 + 51 + 3x + 4 = 360
7x + 136 = 360
7x = 360 - 136
= 224
x = 224 ÷ 7
x = 32

For the price of the backpack to be greater than $15, the following inequality should be satisfied → {x} > 15.
What is inequality?An inequality compares two or more numbers or expressions with one another. For example -
2x + 4y > 7
2x + 5y < 6
Given is that let {x} be the price of a backpack.
For the price of the backpack to be greater than $15, we can write -
{x} > 15.
