It will take 4 people a total of 63 hours to build a deck. How many people are needed to build the same type of deck in 36 hours?

Answers

Answer 1

Well the equation for the given information 63/4 = How long it takes everyone to build the deck
63/4 = 15.75
15.75
567

Answer 2

Well,

63 divided by 4 equals 15.75

So, each person holds 15.75 hours.

15.75 * 2 people = 31.5 hours, so that would not work.

15.75 * 3 people = 47.25, which is the closest you're going to get.

Correct answer: 3 people

Two tons of water is pumped into a tank 15 ft. high in 5 minutes. Determine the power output of the pump.

Answers

Answer:

0.364 horsepower

Step-by-step explanation:

You want to know a pump's power output if it raises 2 tons of water 15 ft in 5 minutes.

Power

The power is conveniently measured in horsepower. One horsepower is 33,000 ft·lb/minute.

Here, we have (2t · 2000 lb/t · 15 ft)/(5 min) = 12000 ft·lb/min

In terms of horsepower, that is ...

(12000 ft·lb/min) / (33000 ft·lb/min/hp) = 4/11 hp ≈ 0.364 hp

The power output of the pump is about 0.364 horsepower.

Additional comment

That's about 271 watts.

The distance dimensions are in feet, so we assume the tons are US short tons of 2000 lb each.

2/5 of the children in a club are girls,if there are 24 boys,how many children are there altogether?how many more boys than girls are there

Answers

2/5 are girls, therefore 3/5 are boys

3/5 = 24
1/5 = 24 ÷ 3 = 8
2/5 = 8 x 2 = 16

Altogether = 16 + 24 = 40

24 - 1 6 = 8

There are 40 children altogether
There are 8 more boys than girls.

8 More Boys

2/5 = 16/40
24 = 3/5

24 - 16 = 8

Therefore, There Are 8 More Boys Than Girls.

what is the domain of the function y=3sqrt(x)

Answers

y=3sqrt(x)

x≥0

Because every number in the domain must yield real number outputs, set what is in the radical greater than or equal to 0.

ANSWER

The domain of the function

[tex]y = 3 \sqrt{x} [/tex]
is
[tex]x \geqslant 0[/tex]

EXPLANATION

The domain of a function refers to all values of x for which y is defined.

Since this is a square root function, we need to keep the expression under the square root sign to be greater than or equal to zero.

As soon as the expression under the root sign is less than zero, the function will not be defined.

This means that the square root of a negative number will not be a real number.

Thus the domain is
[tex]x \geqslant 0[/tex]

or

If two polygons are similar then the corresponding sides are equal and the corresponding angles are proportional. True or False?

Answers

We can say that two polygons are similar if they have the same shape as the other but they are jut different in size. Even when the other polygon is flipped over or rotated, the shape still remains similar. Two polygons are considered similar only if their corresponding sides are proportional and their angles must be congruent.

If the question is phrased like that however, your answer would be false because the sides are not equal, they are proportional. The angles are not proportional, they should be congruent or equal.

Choose the right answer. If the distance on a map from point R to point T measures 3.0 inches and the scale is 1 inch = 0.5 miles, what is the distance in miles from point R to point T? ______ miles
A. 6.0
B. 3.0
C. 1.5

Answers

The answer is c because when you multiply 3.0 by 0.5 I️t gives you 1.5

Answer: The distance from point R to point T is 1.5 miles.

Step-by-step explanation:

In the map, the scale is,

1 inches = 0.5 miles,

3 inches = 3 × 0.5 = 1.5 miles,

Thus, in the map 3 inches shows 1.5 miles,

Since, in the map, the distance from point R to point P = 3 inches,

Thus, the actual distance from point R to point P = 1.5 miles.

What is 0.673 rounded to the nearest hundredths

Answers

Your answer will be 0.67

Hope this helps

0.673 rounded to the nearest hundredth as 0.67

The digit in the smallest location is unaffected if it is less than 5 in number. Rounding down is the process of reducing a number to zero after a certain number of digits. The digit in the smallest location is added with +1 if it is bigger than or equal to 5.

To round off 0.673 to the nearest hundredth means hundredth digit after decimal, To do so take a look on the thousandth digit after decimal, If it is greater than 5 or equal to 5 increase the hundredth digit after decimal by 1 otherwise no change,

Here, the thousandth digit is 3, 3<5. So, no increment is required.

It will remain as 0.67.

Thus, 0.673 is 0.67 after rounding off to the nearest hundredth.

Can someone please explain this to me? I keep getting -infinity as the answer.

Answers

There is an indeterminate form: infinity/infinity. To solve it, you can use the infinite comparison method. First, you have to identify which has the highest degree term: whether the numerator or the denominator. In this case, it is the numerator, which has the negative term of degree 4: -7x ^ 4. Then, the result is -∞.

Therefore, the answer is the last option: Does not exist.

△ XYZ∼ △ DEF, YZ is 10 meters, XZ is 15 meters, and EF is 8 meters. What is DF?

Answers

im not for sure on this but i would say DF is 13

△ XYZ∼ △ DEF, YZ is 10 meters, XZ is 15 meters, and EF is 8 meters. What is DF?

Solution:

As, △ XYZ∼ △ DEF , so the ratio of sides of triangle is equal.

So, we have, [tex] \frac{XY}{DE} =\frac{YZ}{EF} =\frac{XZ}{DF} [/tex]

Using, [tex] \frac{YZ}{EF} =\frac{XZ}{DF} [/tex]

So, we get,[tex] \frac{10}{8} =\frac{15}{DF} [/tex]

Now, to solve for DF, we must simplify

Simplifying,[tex] \frac{10}{8} =\frac{5*2}{4*2}=\frac{15}{DF) [/tex]

[tex] \frac{5}{4} =\frac{15}{DF} [/tex]

To simplify, Let us multiply by 4*DF on both sides

[tex] \frac{5*4DF}{4} =\frac{15*4DF}{DF} [/tex]

[tex] \frac{5DF}{1} =\frac{15*4}{1} [/tex]

So, 5 DF=15*4=60

To solve for DF, let us divide by 5 on both sides

[tex] \frac{5}{5} DF=\frac{60}{5} [/tex]

[tex] \frac{1}{1} DF=\frac{12}{1} [/tex]

So, DF=12meters

There is an old riddle about a frog at the bottom of a 20-foot well. if he climbs up 3 feet each day and slips back 2 feet each night, how many days will it take him to reach the 20-foot mark and climb out of the well?

Answers

For this case what we are going to do is write step by step the equation of the line
f (x) = mx + b
We have:
20-foot well:
f (x) = mx + 20
if he climbs up 3 feet each day and slips back 2 feet each night:
f (x) = - 3x + 2x + 20
f (x) = - x + 20
When it reaches 20 feet we have f (x) = 0:
f (x) = - x + 20
0 = -x + 20
x = 20 days.
Answer:
It will take him 20 days to reach the 20-foot mark and climb out of the well
