Ron is five years older than twice his cousin Pat’s age. The sum of their ages is less than 35. What is the greatest age that Pat could be? 7,8, or 10? Please more then one response so I know its right,

Answers

Answer 1
To make this problem simple, let's make Pat's age be 'a' for age. So is Ron is 5 years older than double a, Ron is 2a+5 years old. If their ages added together are less that 35 we have a + 2a + 5 < 35 Simplifying by collecting like terms, 3a +5 < 35 and subtracting 5 from each side, 3a<30 dividing each side by 3, a<10 So the greatest age Pat could be is infact 9 (as his age has to be less than 10)

The engine of a car has a displacement of 305 cubic inches. what is the displacement in cubic feet? round your answer to 2 decimal places.

Answers

 solution
 1 inch = 2.54 centimeters
Therefore, to convert to cubic measurements
 (1 in)³ = (2.54 cm)³
 Thus;
1 in³ = 16.387 cm³
Hence 305 cubic inches will be equivalent to
  305 × 16.387
 = 4998.035 cm³

Answer:

0.18 cubic feet (in 2 decimal places)

Step-by-step explanation:

The relationship between the unit of measurement inches and the unit of measurement feet may be expressed mathematically as

12 Inches = 1 feet

finding the cube of both sides i.e both sides to the power of 3,

1728 cubic inches = 1 cubic feet

therefore,

305 cubic inches

= 305/1728 cubic feet

= 0.1765 cubic feet

f(x)=9x^3−27x+9, [0,3],

Answers

First we find the critical points by taking the first derivative and setting it equal to zero. So y'=27x^2-27=27(x^2-1)=27(x+1)(x-1)=0. The critical points are x=-1 and x=1. But we have a closed interval here and x=-1 is not in that interval. We must check the values of the endpoints and x=1, the critical point. We substitute those back into the original and get y(0)=9, y(1)=9-27+9=-9 and y(3)=9(3)^3-27*3+9=171. When it asks for values, it is asking for y values. The absolute minimum is -9 and the absolute maximum value is 171.

0.1 2.55
0.2 -14.4
0.3 -7.35
0.4 11.6
0.5 11.3

Answers

Answer: With the given information, it appears that the period of the pendulum is about 0.45 seconds.

The period is the length of one complete cycle of the pendulum. That mean that is will start positive go negative and return to positive. 

If we assume that time 0 is the start with an angle of 15  degree, then we are looking for the point in the graph where it returns to about 15 degrees.

If you create a scatter plot of the data, it would appear that it would reach 15 between 0.4 and 0.5 seconds. At 0.4 it is at 11.6, then it moves up. At 0.5, it is on it's way down at 11.3.

It is safe to assume that it reached 15 between these points to complete one period.

Answers

the answer will be
[tex] \frac{4}{5} = 0.8[/tex]
hope this helps

Answer:  The correct option is (A) 0.8.

Step-by-step explanation:  Given that a  large bag of marbles contains an equal amount of red, orange, yellow, blue, and green marbles. Brody randomly selects 1 marble from the bag.

We are to find the probability of selecting a red, blue, yellow or green marble.

Let n be the number of each color of marbles in the bag.

That is, the number of red, orange, yellow, blue, and green marbles, each equals n.

Let S denote the sample space of selecting a marble from the bag and A denote the event of selecting a red, blue, yellow or green marble.

Then, we have

n(S) = n + n + n + n + n = 5n,

n(A) = n + n + n + n = 4n.

Therefore, the probability of event A is given by

[tex]P(A)=\dfrac{n(A)}{n(S)}=\dfrac{4n}{5n}=\dfrac{4}{5}=0.8.[/tex]

Thus the required probability selecting a red, blue, yellow or green marble is 0.8.

Option (A) is CORRECT.

Please help thank you!

John and Matt are going to fill a pool with 2 different sized hoses. John can fill the pool in 5 hours, while Matt can complete it in 10 hours. Explain each step in solving this equation.

Answers

the complete question is
John and Matt are going to fill a pool with 2 different sized hoses. John can fill the pool in 5 hours, while Matt can complete it in 10 hours.How long will it take both to fill the pool? Explain each step in solving this equation.

we know that
John can fill the pool in --------------> 5 hours
therefore
I calculate the amount of pool that John fills in one hour
if John can fill 100% of the  pool in----------------> 5 hours
X--------------------------------------> 1 hour
X=1/5=0.20 pool/hour

Matt  can fill the pool in --------------> 10 hours
therefore
I calculate the amount of pool that Matt  fills in one hour
if Matt can fill 100% of the  pool in----------------> 10 hours
X--------------------------------------> 1 hour
X=1/10=0.10 pool/hour

adding both amounts

(0.20+0.10)=0.30 -----------> 30% pool/hour
then
if both can fills 30% of the  pool in----------------> 1 hour
100%-------------------------------> X
X=100/30=3.33 hours----------> 3 hours + 19 minutes+ 48 sec

the answer is 3.33 hours (3 hours + 19 minutes+ 48 sec)

Can someone please help me solve for x and y? Thank you

Answer: 
Choice D) x*y = -10

============================================

Explanation:

Multiply both sides of the first equation by 10 to clear out the fractions (10 is the LCD)
3x/5 + y/2 = 13/10
10*(3x/5 + y/2) = 10*(13/10)
6x + 5y = 13

Multiply both sides of the second equation by 100 to get each decimal value to turn into a whole number (move the decimal point over 2 spots to the right)
0.5y + 0.04x = 2.42
50y + 4x = 242
4x + 50y = 242

So we have this new system of equations which is equivalent to the original system
6x + 5y = 13
4x + 50y = 242

Multiply both sides of the top equation by 10 so that the 5y turns into 50y
6x + 5y = 13
10*(6x + 5y) = 10*13
60x + 50y = 130

Now we have this system of equations
60x + 50y = 130
4x + 50y = 242

If we subtract straight down then we have
60x-4x = 56x
50y-50y = 0y = 0 ... notice how the y terms go away effectively
130-242 = -112

The y terms go away leaving us with this simplified equation
56x = -112
Which solves to
x = -2
when we divide both sides by 56

Now use that x value to find y
6x + 5y = 13
6(-2) + 5y = 13 ... replace x with -2
-12 + 5y = 13
-12+5y+12 = 13+12 ... adding 12 to both sides
5y = 25
5y/5 = 25/5 .... dividing both sides by 5
y = 5

In summary we have x = -2 and y = 5. Therefore, x*y = -2*5 = -10 is the answer

He lay on his armour-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections. The bedding was hardly able to cover it and seemed ready to slide off any moment. His many legs, pitifully thin compared with the size of the rest of him, waved about helplessly as he looked. (2)"What's happened to me?" he thought. It wasn't a dream. His room, a proper human room although a little too small, lay peacefully between its four familiar walls.

It showed a lady fitted out with a fur hat and fur boa who sat upright, raising a heavy fur muff that covered the whole of her lower arm towards the viewer. (3)Gregor then turned to look out the window at the dull weather. Drops of rain could be heard hitting the pane, which made him feel quite sad. "How about if I sleep a little bit longer and forget all this nonsense", he thought, but that was something he was unable to do because he was used to sleeping on his right, and in his present state couldn't get into that position. However hard he threw himself onto his right, he always rolled back to where he was.
