Answer:
The speed of the plane is [tex]v=1.2\: m/s[/tex]
Step-by-step explanation:
The vector (5,6) represents a point in the coordinate system time-position.
So, we have that at t = 5 s the position is x = 6.
Let's recall that the slope of this vector is the speed, then using the tangent definition:
[tex]v=\frac{x}{t}=\frac{6}{5}[/tex]
[tex]v=1.2\: m/s[/tex]
I hope it helps you!

Shiva uses 8.2 pints of blue paint and white paint to paint her bedroom walls. 3/4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer: 2.05 pints
Step-by-step explanation:
Shiva used 8.2 pints in total to paint the bedroom.
3/4 of this was blue paint which means that the remaining 1/4 is white paint.
Pints of white paint used:
= Proportion of white paint * Total pints used
= 1/4 * 8.2
= 2.05 pints

If you flip a coin and roll a 6-sided die, what is the probability that you will flip a heads and roll an even number?
Answer:
The probability for getting a head and an even number is 0.25.
Step-by-step explanation:
S be the sample space of the event = { (H,1) ,(H,2) ,(H,3) ,(H,4) ,(H,5) ,(H,6) ,(T,1) ,(T,2) ,(T,3) ,(T,4) ,(T,5) ,(T,6) }
∴ n(S) = 12
Let A be the event getting a head and an even number when a coin is tossed and a six sided dice is rolled
Jesse now has $200 and his goal is to buy a bicycle that costs $375. He earns $10 for every car that he washes. Write an inequality that represents the number of cars Jesse must wash in order to afford the bicycle. Then, solve the inequality to determine the number of cars Jesse must wash in order to afford the bicycle. Show all of your work and remember to include units.
Answer:
$200 + $10x = $375
Well we're going to round up to $380, cause their making money in increments of 10 rather than 5.
And based off that I'd subtract $375 from $200 (375 -200 = 180)
Then take that answer and divide it by 10. (180 / 10)
Jesse will need to wash at least 18 more cars in order to afford the bicycle

One of the legs of a right triangle measures 1 cm and its hypotenuse measures 4 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
3.9 cm
Step-by-step explanation:
One of the legs of a right triangle measures 1 cm and its hypotenuse measures 4 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
We can solve the above question using Pythagoras Theorem
Hypotenuse ² = Opposite ² + Adjacent ²
From the above question
Hypotenuse = 4 cm
1 leg = Opposite = 1 cm
Other leg = Adjacent = x
Hence
4² = 1 ² + x²
x² = 4² - 1²
x = √ 16 - 1
x = √15
x = 3.8729833462 cm
Approximately to the nearest tenth = 3.9 cm
The measure of the other leg is 3.9 cm
Yuto has a bag containing 3 red marbles, 5 blue marbles, 2 green marbles, and 8 yellow marbles. Rin reaches into the bag, pulls out a blue marble, and puts it in her pocket. Then Misaki reaches in and pulls out a marble. What is the total number of possible outcomes for Misaki’s marble?
Answer:
17
Step-by-step explanation:
If Rin pulls out 1 blue marble from the bag then total marbles left in the bag now= 18 − 1 = 17
Now Misaki pulls out a marble: Probability of red marble= 3/17
probability of blue marble= 4/17

Are the following two expressions equivalent?
Explain how you know...
3(4-x)
6(x+2)-7x
Answer:
no, because the first=12-x
and the second=-1x+2
Step-by-step explanation:
Answer:
No, they are not equivalent.
Step-by-step explanation:
First, we simplify the two expressions.
3(4 - x) = 12 - 3x We multiply everything inside the bracket by 3.
6(x + 2) - 7x = 6x + 12 - 7x = 12 - x Using BODMAS/BIDMAS, we first multiply everything in the brackets by 6 and then simplify.
If we compare 12 - 3x to 12 - x, we can clearly notice that they aren't equivalent. If they were to be equivalent, they would have to be exactly the same values as each other. The 12 is common in both expressions, but the -3x and -x differ, therefore the following two expressions aren't equivalent.

Theta = arctan(-4/4)
theta = arctan(-1)
theta = -45
theta = 180 - 45
theta = 135 degrees
x = rcos theta
y = rsin theta
x = 4√2cos 135
y = 4√2sin135

The grades of a statistics midterm are normally distributed with a mean of 70 and a standard deviation of 2. Without using a calculator, what is the probability that a student will receive a grade between 74 and 76? 4.30% 2.15% 34.12% 13.6%
Answer:
.13.5%
Step-by-step explanation:
The probability that a student will receive a grade between 74 and 76 is calculated as follows:
µ+2σ=70+2(2)=70+4=74
µ+3σ=70+3(2)=70+6=76
From the above empirical rule it can be observed that 13.5% of observations fall in between 1 and 2 standard deviations above the mean.
Therefore, the probability that a student will receive a grade between 74 and 76 is 13.5%.
Thus, the correct options is A.13.5%.

A patio 2 pairs of two parallel sides and 2 pairs of sides that are the same length there are 4 square corners what shape is the patio
Answer:
The patio is a rectangle
Step-by-step explanation:
Since it is given that we have 2 pairs of two parallel sides, which implies 4 sides, this thus shows that the shape is a quadrilateral since, only quadrilaterals have 4 sides. Also, 2 pairs of sides are the same length, and are parallel, it shows that the shape is likely a rectangle.
Finally, there are 4 square corners on the shape which implies 4 right angles. This confirms that our shape is a rectangle since only a rectangle has 2 pairs of two parallel sides and 2 pairs of sides that are the same length there are 4 square corners.
So, the patio is a rectangle.
