Answer:

1248' x 2056' so I think you missed copying decimals but I would asume B

Step-by-step explanation:

312''x(1/(1/4''))=1248'

514''x(1'/(1/4''))=2056'

The dimensions in feet's are 1248' x 2048'.

We have architectural drawing scale -  1' = 1/4"

We have to convert the dimensions 312" by 514" into feet's.

double prime (″) is symbol for inches.

single prime (') is a symbol for foot(singular)/ feet's (plural)

1 foot =12 inches.

According to the question -

1' = 1/4"

1 foot = 1/4'' inches

Then, 1 inches will have = [tex]\frac{1}{\frac{1}{4} }[/tex] = 4 feet's.

Therefore -

312" = 312 x 4' = 1248 feet's

514" = 512 x 4' = 2048 feet's

Hence, the dimensions in feet's are 1248' x 2048'.

Answer:

181m - 38

Step-by-step explanation:

Hey there!

9(20m – 5) + (m + 7)

DISTRIBUTE

9(20m) + 9(–5) + m + 7

9(20m) + 9(–5)

9(20m) = 180m

Answer:

3y = 11x-16

Step-by-step explanation:

The general equation of a line that passes through two points can be written as;

y = mx + b

where m is slope and b is the y-intercept

Mathematically in this case;

m = (9-(-2)/(5-2) = 11/3

To write the equation, we use the one-point form

y-y1 = m(x-x1)

(x1,y1) = (2,-2)

y + 2 = 11/3(x-2)

y = 11x/3-22/3+ 2

y = 11x/3 -16/3

so;

3y = 11x - 16

Answer:

x=10

y=25

Step-by-step explanation:

3x-10+5x+30+6x+20=180

14x+40=180

14x=180-40

14x=140

x=10

9x-10=4y-20

9(10)-10=4y-20

90-10=4y-20

80=4y-20

80+20=4y

100=4y

25=y

Answer:

She could plant 9 plants.

Step-by-step explanation:

1 1/2 hours = 90 minutes, so 12 plants per 90 minutes. Which would mean 6 plants per 45 minutes. So in between 45 and 90 minutes (1 hour), and in between 6 and 12 plants (9).

Sorry if you didn't understand, I'm bad at explaining.

Step-by-step explanation:

The coordinates of the point is (15, 12).

      Point dividing the line segment AB in the ratio of 1 : 4 will have the coordinates as (15, 12)

        [tex]h=\frac{mx_2+nx_1}{m+n}[/tex], [tex]k=\frac{my_2+ny_1}{m+n}[/tex]

If a segment having extreme ends A(7, -2) and B(47, 68) is divided by a point P(h, k) in the ratio of 1 : 4

h = [tex]\frac{1(47)+4(7)}{1+4}[/tex]

h = 15

k = [tex]\frac{1(68)+4(-2)}{1+4}[/tex]

k = 12

   Therefore, coordinates of the point dividing the segment AB in the ratio of 1 : 4 will be (15, 12).

Answer:

pipe will empty the tank in 10.5 hours, working alone.

Step-by-step explanation:

Let x be the rate of work of the slower pipe (measured in the tank volume per hour).

Then the rate of work of the faster pipe is 2.5x of the tank volume per hour.

The combined rate of the two pipes is then  x + 2.5x = 3.5x.

We are given

7.5*3.5*x = 1;  hence   x = 1%2F%287.5%2A3.5%29.

Then  2.5x = 2.5%2F%287.5%2A3.5%29 = 1%2F%283%2A3.5%29 = 1%2F10.5.

It means that the faster pipe will empty the tank in 10.5 hours, working alone.

The faster pipe will empty the tank in 10.5 hours, working alone.

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.

Let x be the rate of work of the slower pipe (measured in the tank volume per hour).

Then the rate of work of the faster pipe is 2.5x of the tank volume per hour.

The combined rate of the two pipes is then  x + 2.5x = 3.5x.

We are given

7.5×3.5×x = 1

7.5×3.5 x=1

Divide both sides by 7.5×3.5

x=1/ 7.5×3.5

2.5x=2.5/ 7.5×3.5

x=1/10.5

It means that the faster pipe will empty the tank in 10.5 hours, working alone.

Hence, the faster pipe will empty the tank in 10.5 hours, working alone.

Answer:

15miles//hr

Step-by-step explanation:

From the question, we are given;

Distance covered by Paola = 3/5 miles

Time = 1/25 of an hour

Speed = Distance/ time

Substitute

Speed = (3/5)/(1/25)

Speed = 3/5 * 25/1

Speed = 3 * 5

Speed = 15

Hence Paola's running speed in miles per hour is 15miles/hr

Answer:

1.5 inches

Step-by-step explanation:

1 inch = 16 miles

x = 24 miles

Cross multiply

16x = 24*1          

Divide by 16

x = 24/16

x = 3/2 = 1.5

The answer is below

Step-by-step explanation:

How much sleep do high school students get on a typical school night? An interested student designed a survey to find out. To make data collection easier, the student surveyed the first 100

students to arrive at school on a particular morning. These students reported an average of 7.2 hours of sleep on the previous night.

(a) What type of sample did the student obtain?

(b) Explain why this sampling method is biased. Is 7.2 hours probably higher or lower than the true average amount of sleep last night for all students at the school? Why?

Solution:

a) A voluntary response sample is a sample made up of volunteers. It samples more people who have strong opinions and sample people who have less opinion on the survey. It is biased.

Convenience sample is a type of sampling where the group of people are conveniently selected from a population. It is biased.

Since the first 30 students to arrive at school on a particular morning was used, this is convenience sampling since only the first 30 was conveniently selected.

b) This sampling method is biased because the first 30 students are those who would have woken up earlier while those who woke up late would not be sampled.

This means that the 7.2 hours is lower than the true average amount of sleep last night for all students at the school
