find the difference between the first and second hour earnings to get 10.
get the difference of the second and third to get 12.
we realize that they are in increasing with even numbers from 10 going further, ie, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28....etc
to get the total earnings for the 24 hrs, you have to keep on adding the next even number till you reach the 24th hour
you will get $786.

According to the key of a particular park map, every 8 inches on the map represents 3 miles of trails in the park. How many inches on the map represents 9 miles on the park trails
Answer:
24 inches represents 9 miles in the map
Step-by-step explanation:
To solve this problem you take into account that 8 inches represents 3 miles and that x represent the number of inches for 9 miles. That is:
8 ------- 3
x ------- 9
This is simply a rule of three, then you calculate:
[tex]x=\frac{8\ x\ 9}{3}=\frac{72}{3}=24[/tex]

Nina woke up at 8:00 A.M. At noon the temperature had risen 8°F. By 1:00 P.M. The temperature had risen another 4°F. There was a thunderstorm at 4:00 P.M. By 7:00 P.M. The temperature had fallen 11°F since 1:00 P.M. To 62°F. What was the temperature when Nina woke up?
Answer:
61 °F
Step-by-step explanation:
If T is the temperature at 8 a.m., we have ...
T +8 +4 -11 = 62
T +1 = 62
T = 61 . . . . . . subtract 1
The temperature was 61 °F when Nina woke up.
A game comes with a deck of cards with each card showing one of the numbers 2,3,4,5,6, or 8. Each card occurs one time in red and one time in purple, and one time in blue. Given that a blue card is drawn what is the probability the card is 4
Answer:
0.1667 = 16.67%.
Step-by-step explanation:
We already know that the card drawn is blue, so now we need to check the value of the card.
The blue cards have 6 possibilities of values (2, 3, 4, 5, 6 or 8), and the number 4 appears only 1 time, so the probability of the blue card having the value 4 is the number of times this value occurs by the number of possible values:
P = 1/6 = 0.1667 = 16.67%.

Jose's ball is stuck on the roof of his home, which is 8 feet high. He wants to use a ladder to climb up and get his ball. If he sets the base of the ladder 6 feet away from his home, what is the minimum length that the ladder can be? Explain how you solved this question using context and at least three sentences. Hint: Draw your the scenario and label given values.
Answer:
10 feet
Step-by-step explanation:
It becomes a right-angled triangle with height of 8feet and base of 6feet.
Using Pythagoras theorem:
a² = b² + c²
a² = 8² + 6²
a² = 64 + 36
a² = 100
a = √100
a = 10

A mixture of gases was found to have a total pressure of 950 mmhg gas number 1 has a pressure of 335 mmhg gas number 2 has a pressure of 456 mmhg what is the pressure exerted by gas number 3
Answer:
The pressure exerted by gas number 3 is 159 mmHg
Step-by-step explanation:
To answer this question, the law to Use is Dalton’s law of partial pressure
Dalton’s law of partial pressure states that for a mixture of gases which do not mix, the total pressure exerted by such gases is equal to the sum of the individual pressure.
Now for the three gases, the total pressure Pt is equal to P1 + P2 + P3
Now we have Pt = 950 mmHg, P1 = 335 mmHg and P2 = 456 mmHg
P3 = Pt-P1-P2
Plugging the values above, we have ; 950-335-456 = 159 mmHg

Um criador de peixes decidiu construir um tanque para criar uma nova espécie de peixe, porém essa precisa de um tanque muito maior do que ele costuma trabalhar e seu formato precisa ser de um paralelepípedo. Sabendo disso, pediu a um engenheiro que construísse um tanque com 50 m³ de volume, (x + 3) metros de comprimento, a largura x metros e a altura de 5 metros. Qual o comprimento e a largura desse tanque, respectivamente?
Answer:
length = 5 meters
width = 2 meters
Step-by-step explanation:
The volume of parallelepiped is given by:
Volume = length * width * height.
If the volume is 50 m3, the length is x + 3, the width is x and the height is 5 m, we can use the volume equation to find the value of x:
50 = (x+3) * x * 5
10 = (x+3) * x
x^2 + 3x - 10 = 0
Using Bhaskara's formula, we have:
Delta = 3^2 + 4*10 = 49
sqrt(Delta) = 7
x1 = (-3 + 7)/2 = 2
x2 = (-3 - 7)/2 = -5 (This value would cause negative measurements, so it is not a valid answer)
So with the value of x = 2, we can find the length and the width of the tank:
length = x + 3 = 2 + 3 = 5 meters
width = x = 2 meters
find the value of x
-3=16-x

Step-by-step explanation:
The garden has an area of 28 square meters. The length of the garden is 7 meters. What is the width of the garden?
You have to find the width
Answer:
The answer is 4
Step-by-step explanation:
Since the total area is 28, and the length is 7. Therefore 28 divided by 7 equals 4.
Hope this helps
Answer:
4 meters
Step-by-step explanation:
Let's assume this is a rectangular garden.
The area of a rectangle can be found using:
a=l*w
We know the area is 28 square meters and the length is 7 meters. We can substitute 28 in for a, and 7 in for l.
28=7*w
Now we need to solve for w. To solve, we have to get w by itself. 7 and w are being multiplied. To reverse this, divide both sides by 7.
28/7=7*w/7
28/7=w
4=w
The width is 4 meters

Step-by-step explanation:
The circumference of a circle is the distance around the outside of a circle. If we can find the circumference of the wheel, we can find out how far Elena can travel when her wheel turns one time. If we can find out how far she travels in one wheel turn, we will multiply that distance by 840 to see how far she travels when her wheels turn 840 times.
[tex]C=2\pi r[/tex] and
C = 2(3.14)(.25) so
C = 1.57 m
1.57 x 840 = 1318.8 meters
Suppose Tommy walks from his home at (0, 0) to the mall at (0, 6), and then walks to a movie theater at (7, 6). After leaving the theater Tommy walks to the store at (7, 0) before returning home. If each grid square represents one block, how many blocks does he walk?
Answer:
26 blocks
Step-by-step explanation:
To determine the number of blocks Tommy walked, you will calculate the distances between each of his points (ordered pairs).
Using the distance formula i.e[tex]\sqrt{(c-a)^2+(d-b)^2}[/tex]
(0,0) to (0,6) is : [tex]\sqrt{(0-0)^2+(6-0)^2}[/tex] = 6 blocks
(0,6) to (7,6) is: [tex]\sqrt{(7-0)^2+(6-6)^2}[/tex]= 7 blocks
(7,6) to (7,0) is: [tex]\sqrt{(7-7)^2+(0-6)^2}[/tex] = 6 blocks
(7,0) to (0,0) is: [tex]\sqrt{(0-7)^2+(0-0)^2}[/tex] = 7 blocks, back home
This totals 26 blocks that Tommy walked.
The sea turtle habitat at the zoo is made by connecting two large aquariums. The first aquarium is 6 m long, 4 m wide, and 2 m high The second aquarium is 8 m long 9 m wide and 3 m high how many cubic meters of space do the sea turtles have in their habitat
Answer:
264 cubic metres
Step-by-step explanation:
We need to find the volume of both aquariums and add them up.
The aquariums are shaped as rectangular prisms.
The volume of a rectangular prism is:
V = L * W * H
where L = length, W = width, H = height
The first aquarium is 6 m long, 4 m wide, and 2 m high. Its volume is:
V = 6 * 4 * 2 = 48 cubic metres
The second aquarium is 8 m long, 9 m wide and 3 m high. Its volume is:
V = 8 * 9 * 3 = 216 cubic metres
The amount of space the turtles have is therefore:
V = 48 + 216 = 264 cubic metres

work out ⅕ of 80
work out 48÷½
❤︎シ︎✌︎
Step-by-step explanation:
1/5×80=80/5=16 because 1/5 out of 80 means to multiply 1/5 by 8o so the answer to that question is 16.
48÷1/2=48×2/1=96/1=96 because when you divide a fraction by fraction or a fraction with a number there is a rule that says you have to reverse the fraction on the right side and replace the division sign to a multiply sign and multiply. so the answer becomes 482)×2/1 which equals 96.
