Two boats started to move towards each other from two boat stations, located 30 miles apart. One boat moved at a speed of 3 miles per hour, the other moved twice as fast. How soon will the boats meet?
Answer:
The boats will meet in 3.33 hours.
Step-by-step explanation:
The position of each boat can be modeled by a first order equation.
I am going to say that the first boat is at the position 0, and moving in the positive direction with a speed of 3 miles per hour. So
[tex]A(t) = 0 + 3t[/tex]
They are moving in oppositie directions, and initially are 30 miles apart. This means that the second boat starts at the position 30, and moves in the negative direction at the rate of 6 miles an hour. So
[tex]B(t) = 30 - 6t[/tex]
How soon will the boats meet?
This is t when:
[tex]A(t) = B(t)[/tex]
[tex]3t = 30 - 6t[/tex]
[tex]9t = 30[/tex]
[tex]t = \frac{30}{9}[/tex]
[tex]t = 3.33[/tex]
The boats will meet in 3.33 hours.

Reeva's family budget is shown. She works 165 hours each month. With the given
information, what is the minimum hourly wage she would need to earn to cover her monthly expenses?
Add all her expenses =2024.08
Then divide by 165=12.268
Go with choice 12.27
Answer:
$12.27, B, top left answer thingie on ttm
Step-by-step explanation:
To solve, you need to add her expenses of everything to get 2024.08.
You know she works 165 hours each month, so you need to divide the 2024.08 total expenses by 165 to get her minimum hourly wage. 2024.08/165 = 12.267151515....
You can only have two decimals in money so just round up to make it easier so 12.267151515 ~ 12.27.
Hence 12.27.

D. I
NA
Huh?
Answer:
x = -1
Step-by-step explanation:
6x + 14 = 7 - x
Add x to each side
6x+x + 14 = 7 - x+x
7x+14 = 7
Subtract 14 from each side
7x+14-14 = 7-14
7x = -7
7x/7 = -7/7
x = -1

Total cost(TC) =fixed cost+(variable per unit*x)
for general purpose equipment:
TC=125,000+18x equation 1
for flexible manufacturing system
TC=250,000+14x equation 2
for dedicated machine
TC=480,000+13x equation 3
if we set equations 1 and 2 together
125,000+18x=250,000+14x
If we equate equations 2 and 3 together
250,000+14x=480,000+13x
14x-13x=480,000-250,000
x=230,000
18x-14x=250,000-125,000
4x=125,000
divide both sides y 4
x=125,000/4=31250

There were the most observations of female tokoeka kiwis in the given frequency table so option (A) will be correct.
What is a frequency table?A frequency table is a list of objects with the frequency of each item shown in the table.
The frequency of an occurrence or a value is the number of times it happens.
Given the frequency table of kiwi birds with their gender.
Number of female tokoeka kiwis = 44
Now if we look at the table there is none of any bird that is greater than 44 which means it is the most observations in the research.
Hence "There were the most observations of female tokoeka kiwis".

Brianna and Ava go to the movie theater and purchase refreshments for their friends. Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. Using these equations, determine and state the price of a drink, to the nearest cent.
Answer:
2p + 2d = 39 ____________(1)
8p + 10d = 174.50 _________(2)
Price of one drink is $9.25
Step-by-step explanation:
Let the price of a bag of popcorn be p.
Let the price of a drink be d.
Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. This implies that:
2p + 2d = 39 ____________(1)
Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. This implies that:
8p + 10d = 174.50 _________(2)
We now have two system of equations which we can use to find the price of a bag of popcorn and drink:
2p + 2d = 39 ____________(1)
8p + 10d = 174.50 _________(2)
Multiply (1) by 4 subtract from (2):
8p + 10d = 174.50 _______(2)
- 8p + 8d = 156 __________(1)
2d = 18.50
=> d = $9.25
The price of one drink is $9.25

Can adjacent angles be complementary?
Give a brief explanation as to why or why not.
Answer:
Two adjacent angles can be complementary
Step-by-step explanation:
if they add up to 90°. For example, a diagonal of a square will split the right angle into two equal angles; 45°+45°. In a right triangle, the altitude from a right angled vertex will split the right angle into two adjacent angles; 30°+60°, 40°+50°, etc.

Ethan has partially filled the prism with 8 unit cubes. How many more cubes does he need to fill the prism completely A:10 B:15 C:19 D:21 Help me please!!!???!
Corrected Question
Ethan has partially filled the prism with 8 unit cubes.
A rectangular prism with length, height, and width of 3.
How many more cubes does he need to fill the prism completely?
Answer:
(C)19
Step-by-step explanation:
First, we determine the volume of the rectangular prism
Volume of a rectangular prism = Length X Height X Width
=3 X 3 X 3=27 cubic units
Volume of the Cube=1 cubic unit
The number of unit cubes that will fill the rectangular prism = 27
Ethan has partially filled the prism with 8 unit cubes, we subtract 8 from 27 to determine the number left to fill the prism
27-8=19.
Therefore, Ethan will need 19 more cubes to fill the rectangular prism.
The correct option is C
A dolphin jumped up out of the water and back into the water in a parabolic path. (H) height (t) seconds . H=-8(t-0.5)^2+2 . How long will the dolphin be in the air?
Answer:
4 seconds
Step-by-step explanation:
using the vertex formula of a quadratic,
[tex]a(x-h)^{2} + k[/tex], where (h,k) is the vertex
[tex]h = -8(t-0.5)^{2}+2[/tex] h is height and t is time in seconds
the vertex (maximum height) of the dolphin is (h,k) or (0.5, 2)
Height of 1/2
time of 2 seconds
it will take 2 additional seconds to reach the water again.
this can also be solved using quadratic equation, but since it was already set up in vertex form, i'd use that.

A triangle has a base length of (2x - 4) units and a height of (x + 5) units. Write and solve a quadratic equation to determine what value of x gives the triangle an area of 44 square units.
Answer:
x=6
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
44 = 1/2 (2x-4)(x+5)
Multiply the 1/2 time (2x-4)
44 = (x-2) (x+5)
FOIL
44 = x^2 +5x -2x-10
Combine like terms
44 = x^2 +3x -10
Subtract 44 from each side
0 = x^2 +3x -10-44
0 = x^2 +3x -54
Factor
What two numbers multiply to -54 and add to 3
9*-6 = -54
9+-6 = -3
0 = (x+9)(x-6)
Using the zero product property
x +9 =0 x-6 =0
x = -9 x = 6
The height cannot be negative so x cannot be -9
x=6

What is the length of a diagonal of a cube with a side length of 1 cm?
StartRoot 2 EndRoot cm
StartRoot 3 EndRoot cm
StartRoot 4 EndRoot cm
StartRoot 5 EndRoot cm
Answer:
The answer is 3cm
Step-by-step explanation:
The length of a diagonal of a cube with a side length of 1 cm is,
⇒ √3 cm
What is mean by Multiplication?Multiplication means to add number to itself a particular number of times. Multiply will be viewed as a process of repeated addition.
Given that;
A side length of cube is,
⇒ 1 cm
We know that;
The length of a diagonal of a cube with a side length of a cm is,
⇒ d = √3 × a
Here, a = 1
Hence, The length of a diagonal of a cube with a side length of 1 cm is,
⇒ d = √3 × 1
⇒ d = √3 cm

The measure of a straight angle (2x+50) (6x+2)
Answer:
see below
Step-by-step explanation:
If the two angles form a straight angle, their sum is 180
2x+50 + 6x+2 = 180
Combine like terms
8x +52 = 180
Subtract 52 from each side
8x+52-52 = 180-52
8x =128
divide each side by 8
8x/8 = 128/8
x =16
2x+50 = 2(16)+50 = 32+50 = 82
6x+2 = 6(16)+2 =96+2 = 98

A rectangular box is tied with a ribbon so that the ribbon crosses the box at the midpoints of its sides. If the box is 8 inches long, 6 inches wide, and 5 inches high, how long is the ribbon? hint: look for right triangles.
Answer:
The ribbon is 28.4 meters
Step-by-step explanation:
Given the box is 5m high, 6m long, and 8m wide,
we have a right angled triangle with hypotenuse = unknown, x, say
Opposite = 5m and 8m
Then, by Pythagoras theorem
x² = 5² + 8²
x² = 25 + 64
x² = 89
x = √89 ≈ 9.4m
The ribbon is now (5 + 6 + 8 + 9.4)m = 28.4m
f(n)=93+4(n-1) Complete the recursive formula of f(n)
Answer:
f(1) = 93
f(n) = f(n - 1) + 4
Step-by-step explanation:
The recursive formula for an arithmetic sequence is given as:
f(1) = a
f(n) = f(n - 1) + d
where a = first term and d = common difference
An arithmetic sequence is in the form:
f(n) = a + d(n - 1)
where a = first term and d = common difference
The common difference in f(n) = 93 + 4(n-1) is 4.
The first term is 93.
The recursive formula is therefore:
f(1) = 93
f(n) = f(n - 1) + 4
Answer:
f(1)=93
f(n)=f(n-1)+4
Step-by-step explanation:
As you can see in the picture, the initial value is 93, which is why it's the first part of the equation. The 4 is multiplying the (n-1) part in the equation and as we complete the recursive formula of N, you have to put the numbers in the correct order.
