Find three consecutive natural numbers such that the sum of the first and the second is 15 more than the third
Answer: 16, 17 and 18
Step-by-step explanation:
Let the consecutive natural numbers be x, x+1, and x+2. We are informed that the sum of the first and the second is 15 more than the third. This will be:
[x + x + 1] = [x + 2] + 15
2x + 1 = x + 2 + 15
2x + 1 = x + 17
2x - x = 17 - 1
x = 16
The numbers are 16, 17 and 18.
Look at the triangular prism. Work out the volume of the prism.
Answer:
See explanation
Step-by-step explanation:
The question has missing details, as the diagram of the prism is not shown.
However, I'll solve using a general rule.
The volume of a triangular prism is:
[tex]Volume = \frac{1}{2}* b * h * l[/tex]
Where
[tex]b = base[/tex]
[tex]h = height[/tex]
[tex]l = length[/tex]
Take for instance:
[tex]b = 20cm[/tex]
[tex]h = 10cm[/tex]
[tex]l = 5cm[/tex]
The volume is:
[tex]Volume = \frac{1}{2} * 20cm * 10cm * 5cm[/tex]
[tex]Volume = 10cm * 10cm * 5cm[/tex]
[tex]Volume = 500cm^3[/tex]
Another instance (see attachment).
From the attachment:
[tex]b = 4.5cm[/tex]
[tex]h = 5cm[/tex]
[tex]l = 8cm[/tex]
The volume is:
[tex]Volume = \frac{1}{2} * 4.5cm * 5cm * 8cm[/tex]
[tex]Volume = 2.25cm * 5cm * 8cm[/tex]
[tex]Volume = 90cm^3[/tex]
Fifteen bicyclists entered a race. In how many different orders can the top five finish so that awards can be given?
pls help !!
Answer:
They can finish the race in 15 x 14 x 13 x 12 x 11 = 360360 order.
Step-by-step explanation:
There are 15 bicyclists in the race. The first position would come from the first bicyclist to the 15th. Meaning the first position can be occupied by 15 individuals. The second position can only be occupied by 14 individuals since one person is already first. Same way the third, fourth and fifth positions can be occupied by 13, 12 and 11 individuals respectively.
Therefore, they can finish the race in
15 x 14 x 13 x 12 x 11 = 360360 order.

What is the slope of the line -3 y = 12 x + 6?
Answer:
Slope = - 4
Step-by-step explanation:
-3y = 12x + 6
Divide the equation by (-3)

Answer:
Step-by-step explanation:
according the the pythogryamthreme the distance between 30 degress and 40 would vary since the length of 40 would change there by multipling 2 to 40 and 30 then times that by pie then divide it by 2 you should get the value for x, but for y it is more complex you see you much find the slope and plabora of the value x and 40 then using the 2 numbers times it by 30 after divide both numbers to each other resulting in the answer
There are 750 spectators of which of 420 are women and the rear are men what percent of the spectators are women
Answer: 56%
Step-by-step explanation:
There are 750 total people in this crowd.
420 are women and their percentage of the total is needed.
You get this by dividing the number of women by the total number of spectators and then multiplying by 100%:
= Number of women/ Total people * 100%
= 420 / 750 * 100%
= 56%

Learning task 2
A.for this learning task,be able to supply the missing value if y varies jointly or if y varies both directly and inversely to x and z.
Step-by-step explanation:
Row 1
k=2 , Equation: y=2xzRow 2
x=10, k=2Row 3
y= 192, Equation: y= 4xzRow 4
z= 2, k= 3Row 5
x= 16/3, k= 3/4Note. The equation should be y = 3/4xz, not y = 3/4xy
A quantity with an initial value of 8100 decays continuously at a rate of 0.95% per year. What is the value of the quantity after 96 months, to the nearest hundredth?
Answer:
20163.299
Step-by-step explanation:
Initial value = 8100
Rate r = 0.95% = 0.0095
t = 96 month
Therefore, Value of the quantity after 39 decades = Initial value*e^(rt)
= 8100*e^(0.0095*96)
= 8100*e^(0.912)
= 8100*2.48929615041
= 20163.298818321
= 20163.299
So, the value of the quantity after 96 months is 20163.299

During their last game, the Miami Dolphins scored times for a total score of ͵Ͳ points. They scored points for each touchdown and ͵ points for each field goal. Write and solve the systems of equations to find the total touchdowns and field goals scored.
Answer:
The Miami Dolphins had 3 touchdowns and 3 field goals.
Step-by-step explanation:
It is given that During their last game, the Miami Dolphins scored 6 times, for a total score of 30 points. They scored 7 points for each touchdown and 3 points for each field goal.
We need to write and solve the system of equations to find the total touchdowns and field goals scored.
Let x represents the number of touchdowns.
Let y be the number of field goals.
It is given that the Miami Dolphins scored 6 times
[tex]x+y=6[/tex]
[tex]x=6-y[/tex]....(1)
They scored 7 points for each touchdown and 3 points for each field goal.
The total score is 30 points:
[tex]7x+3y=30[/tex] ...(2)
Put the value of x from equation (1) into equation (2).
[tex]7( 6-y)+3y=30[/tex]
[tex]42-7y+3y=30[/tex]
[tex]-4y=30-42[/tex]
[tex]-4y=-12[/tex]
[tex]y=3[/tex]
Put y = 3 in equation 1.
[tex]x=6-3[/tex]
[tex]x=3[/tex]
Hence, the Miami Dolphins had 3 touchdowns and 3 field goals.
Maria is in the state park riding her bike on the new bike trail. She starts at the beginning of the trail and rides for 4 miles. After the first 4 miles, her friend Aiden joins her and they ride the rest of the trail. By the end of the trail, Maria has been riding for two and half hours, while Aiden has been riding for two hours. Assuming they are both riding their bikes at a constant speed the entire time, how long is the bike trail?
Answer:
20 miles
Step-by-step explanation:
If Maria has been riding for 2 1/2 hours and Aiden only for 2. That means that the first 4 miles she rode alone was for 1/2 hour. So that is the rate.
1/2 hour for every 4 miles
Maria rode for 2 1/2 hours divided by 1/2 hours is 5. So 5 x 4mi = 20 miles
Answer:
20 miles
because 4 miles= 1/2 hr

What is the volume of the figure? Enter the answer in the box.
Answer: 2, 700 cubic ft.
Step-by-step explanation:
2420 + 280 = 2, 700
The formula for volume = Length x Width x Height (L x W x H)
11 x 10 x 22 = 2420
7 x 4 x 10 = 280
2420 + 280 = 2, 700
