A plane is flying at a steady speed of 30000m/minute.
How long does it take to fly 2000m. Give your answer in seconds.
SHOW METHOD AND EXPLAIN
Answer:
4 seconds
Step-by-step explanation:
[tex]\frac{30,000}{1} =\frac{2,000}x}[/tex]
The numerator is the distance and the denominator is the time.
I used cross multiplication, the numerator of one fraction times the denominator of the other.
[tex]30,000*x=2,000*1\\30,000x=2,000[/tex]
divide both sides by 30,000 and simplify
[tex]x=\frac{2,000}{30,000} \\x=\frac{2}{30}[/tex]
Then multiply the fractions by 2/2 (basically multiplying the numerator and the denominator each by 2)
[tex]x=\frac{4}{60}[/tex]
Since the denominator is 60, the number of seconds in a minute, the numerator is the answer
I hope this makes sense ;-;

Name two points on the line y = 6x. Does it describe a
proportional relationship?
Answer:
b. Non-proportional
Step-by-step explanation:
A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.
The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:
y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4
Therefore, it is non-proportional.

the required equation for 1 is (x - 2)² = 25 and solution for 2 is x = 2 ± 5
What is the equation?The equation is the relationship between variables and is represented as y =ax + b is an example of a polynomial equation.
part 1
Given equation,
x² - 4x + 3 = 24
x² - 4x + 4 - 4 + 3 = 24
(x - 2)² - 1 = 24
(x - 2)² = 24 + 1
(x - 2)² = 25
Part 2
Solution for the given equation that transformed in part 1 of the solution.
(x - 2)² = 25
(x - 2) = √25
(x - 2) = ±5
x = 2 ± 5
Thus , the required equation for 1 is (x - 2)² = 25 and solution for 2 is x = 2 ± 5

Brian rolls a fair dice 60 times.
How many times would Brian expect to roll a three?
Answer:
10 times.
Step-by-step explanation:
He rolls all the dice independently, so The expected number of 3's is 60 * (expected number of 3's in one throw).
The expected number of 3's in one throw is:
5/6 * 0 + 1/6 * 1 = 1/6
because 5/6 of the time we roll zero 3's and 1/6 of the time we roll one 3 :D
So he should expect (60 * 1/6 = 10) 3's in 60 throws.

Enter the measure of ZCAB to the nearest hundredth degree.
Step-by-step explanation:
sinA=p/h
sinA=12/15
A=sin-¹(4/5)=53.13=53°
<CAB=53°
The measure of ∠CAB is 53°.
What is Trigonometry?The trigonometric function, which comprises the sine, cosine, tangent, cotangent, secant, and cosecant, is one of the six mathematical operations used to describe the side ratios of right triangles (csc).
As per the given data:
From the given diagram, we can clearly understand that the triangle is a right-angled triangle which is right-angled at C.
We have to find out the measure of ∠CAB.
The lengths of the sides BC and AB is also given in the diagram.
For finding out the measure of ∠CAB we can consider BC as the perpendicular and AB as the hypotenuse, and then we have to use the appropriate trigonometric ratio.
The length of the perpendicular BC = 12 units
The length of the hypotenuse AB = 15 units
For relating perpendicular and hypotenuse, we can use the sin trigonometric ratio.
sinθ = Perpendicular / Hypotenuse
sinθ = BC / AB
sinθ = 12 / 15
sinθ = 4 / 5
θ = 53°
The measure of ∠CAB is 53°.
Hence, The measure of ∠CAB is 53°.

There are 12 players on a softball team. The coach has $605 to buy bat bags for all of the players. Each bat bag costs $55. Use the drop-down menus to explain whether the coach has enough money to buy a bat bag for each player... NEED ANSWERS ASAP
Answer:
Yes, he does.
Step-by-step explanation:
55 x 12 = 600
No, The coach does not have enough money to buy a bat bag for each player.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
There are 12 players on a softball team.
The coach has $605 to buy bat bags for all of the players.
Each bat bag costs = $55
Now,
Since, There are 12 players on a softball team.
And, Each bat bag costs = $55
So, The total cost of bag for 12 players = $55 x 12
= $660
Since, The coach has $605 to buy bat bags for all of the players.
And, $605 < $660
Thus, The coach does not have enough money to buy a bat bag for each player.

The volume of the cone will be 2120 cm³, i.e. option B.
What is volume ?Volume is the amount of space that something contains or fills.
volume of the cone [tex]=\frac{1}{3} \pi r^{2} h[/tex]
We have,
Height = 9 cm,
Radius = 15 cm
So,
volume of the cone [tex]=\frac{1}{3} \pi r^{2} h[/tex]
i.e.
volume of the cone [tex]=\frac{1}{3} * 3.14 * 15^{2} * 9[/tex]
On solving we get,
Volume of the cone = 2119.5 = 2120 cm³
Hence, we can say that the volume of the cone will be 2120 cm³, i.e. option B.

Gia can run 4 miles in 32 minutes. At that rate, how many miles can she run in 40 minutes
Answer:
5
Step-by-step explanation:
For these types of problems, we can use cross - multiplication.
4/32 = x/40
Notice that since 40 and 32 are both measured in minutes, we put them on the same line.
Now, like the name suggests, we cross multiply the equation, by doing 4 * 40 = 32 * x. Now, we are left with 160 = 32x. After solving this, we get the answer 5.
