Answer:

5. 1:6 2/5

6. 1:5

Step-by-step explanation:

5. each time in the table you multiply H by 6 2/5 ex.

column 4 , 100x6=600, 2/5 of 100 = 40 and the total is 640, so the contant of proprtionality is 6 2/5

6. in the table there is a point on 2:10 and can be simplified to 1:5 so for every minute 5 gallons of water will be used

hope this helps sorry if this inst what your looking for have a blessed day :)

the answer is B

Step-by-step explanation:

since 10 isn't a perfect square

Answer:

Step-by-step explanation:

x=5

y=-5

Hence it lies in 4th quadrant.

x=r cos θ

5=r cos θ  ...(1)

y=r sin θ

-5 =r sin θ  ... (2)

square and add

(5)²+(-5)²=r²(sin ²θ  +cos ²θ  )

r²=25+25=50

r=±5√2

dividing

tan θ=-5/5=-1=-tan 45°=tan (180-45),tan(360-45)

θ=135°,315°

so polar coordinates are (5√2,315°) and (-5√2,135°)

m<5 = 75°

Step-by-step explanation:

16. Given:

m<1 = 75°; m<3 = 40°

Required:

m<5

Solution:

Since lines A and B are parallel, and m<1 corresponds to m<5, therefore,

m<1 = m<5 (corresponding angles are congruent)

m<1 = m<5 = 75°

m<5 = 75°

Answer:

owes $12.50

Step-by-step explanation:

2.5*5

=12.5

Answer:

-12.5

Step-by-step explanation:

If you do 2.50*5 (because Ms. Ortiz borrows $2.50 every day for 5 days) it equals 12.5, and since it's how much she owes, you have to make it negative, so it's -12.50 or she owes $12.50 (the first one if you are supposed to have the answer be negative, the second one if you have to have it in money form).

Answer:

  64/109 ≈ 0.5872

Step-by-step explanation:

41 + 23 = 64 of the events have outcome E.

An additional 35 + 10 = 45 do not.

The probability of an outcome of E is 64 out of a total of 64+45 = 109 events.

  P(E) = 64/109 ≈ 0.5872

Answer:

B

Step-by-step explanation:

I'm pretty sure it's B, (please let me know if I'm wrong.)  

Colinear means to be on the same straight line, which they are.  

Coplanar means to be in the same plane, which they appear to be as well.

So yeah I'm pretty sure it's B.  

Answer: Raju travels at a higher speed.

Step-by-step explanation:

[tex]Speed =\dfrac{Distance}{Time}[/tex]

Speed inversely proportional to time.

As time taken to cover a particular distance decreases the speed will increase.

Raju covers a certain distance in 1 hour.

Sham covers the same distance in 2 hours.

1< 2

Thus Raju travels at a higher speed.

Answer:x=75

Answer:

A. 6 minutes

Step-by-step explanation:

6 minutes is 1/10 of an hour.

60 minutes is 1 hour.

5,400 minutes is 90 hours.

3 hours is 180 minutes. You can solve this as a proportion:

[tex]\frac{180}{30} =\frac{x}{1}[/tex]

Cross multiply to get 30x = 180. x = 6.

Answer:

45 students

Step-by-step explanation:

Three fifths of the students in the cafeteria bought their lunch from the school. The rest brought their lunch from home. 27 of the students bought their lunch. Let t represent the total number of students in the cafeteria.

We are to calculate the total number of students in the cafeteria.

Fraction of the students in the cafeteria that bought their lunch from the school = 3/5

Number of the students that bought their lunch = 27 students

The total number of students can be calculated as:

3/5 Of t = 27 students

3/5 × t = 27

Cross Multiply

3t/5 = 27

3t = 27 × 5

t = 27 × 5/3

t = 45 students

Therefore, the total number of students in the cafeteria = 45 students

Answer:

x=-4, y=7

Step-by-step explanation:

According to the first equation, y = -4x - 9, so we can substitute y in the second equation for -4x - 9.

y = 3x + 19

-4x - 9 = 3x + 19

Add 9 to both sides

-4x = 3x + 28

Subtract 3x

-7x = 28

Divide by -7

x = -4

Plugging this into the equation, we have:

y = -4x - 9

y = -4(-4) - 9

y = 16 - 9

y = 7

Answer:

600 minutes

Step-by-step explanation:

We start with a bucket that is completely full- it has five gallons of water.

5 gallons of water = 5 (128) fl oz = 640 fl oz

Half of 640 fl oz is 320 fl oz, which is the amount we are looking for.

So, we divide [tex]\frac{320}{8}[/tex] to find how many times it will take for the bucket to become half-full, which is 40 times.

Now, we multiply 40 by 15 minutes, so we get 40 × 15 = 600 minutes

Time for the bucket to become half full is 600 minutes.

Here,

A five-gallon bucket was completely filled with water.

The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes.

We have to find the time for the bucket to become half full.

What is Number system?

A number system is defined as a system of writing to express numbers.

Now,

A five-gallon bucket was completely filled with water.

The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes.

Hence, We start with a bucket that is completely full- it has five gallons of water.

So, Amount of 5 gallons of water = 5 * 128 = 640 fl oz

Now, Half of 640 fl oz = 640/2 = 320 fl oz

So, we divide to find how many times it will take for the bucket to become half-full as;

⇒ 320 ÷ 8 = 40

Now, Time is calculated as to multiply 40 by 15 minutes,

⇒ 40 × 15 = 600 minutes

Hence, Time for the bucket to become half full is 600 minutes.
