36) The speed of a boat in still water is 5km/hr. If the speed of the boat against the stream is 3
km/hr, what is the speed of the stream?
1. 1.5 km/hr
2. 2 km/hr
3. 2.5 km/hr
4. 1 km/hr​

Answers

Answer 1

Answer:

2km/hr

Step-by-step explanation:

Given the following

Speed of boat in water = 5km/hr

Speed of boat against stream = 3km/hr

Since the speed of boat is going against that of the stream, hence, the speed of the stream will be the difference between the speed of boat and that when the boat is against the stream

Speed of stream = 5km/hr - 3km/hr

Speed of stream = 2km/hr

hence the required speed of stream is 2km/hr

Answers

Answer:

(-6, -4)

Step-by-step explanation:

Original coordinates: (6, -4)

POINT S IS 12 UNITS TO THE LEFT OF POINT P.

There are multiple ways to solve this, but I will explain the easiest way.

We can subtract 12 from the x-coordinate.

This because the x-axis runs RIGHT and LEFT.

The y-axis runs UP and DOWN.

6 - 12 = -6

The y-coordinate stays the same.

The new coordinates are: (-6, -4).

Amy knits 1/10 of a scarf in 4/5 of an hour. What fraction of scarf can Amy knit in 1 hour

Answers

Answer:

Amy can knit [tex]\frac{1}{8}[/tex] of a scarf in 1 hour.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

We have that:

1/10 of a scarf - 4/5 of an hour

x of a scarf - 1 hours.

Applying cross multiplication:

[tex]\frac{4x}{5} = \frac{1}{10}[/tex]

[tex]x = \frac{5}{10*4} = \frac{5}{40} = \frac{1}{8}[/tex]

A brand of uncooked spaghetti comes in a box that is a rectangular prism with a length of 10 inches, a width of 3 inches, and a height of 4 1/2 inches. What is the surface area?

Answers

Answer:

The surface area is 177 square inches

Step-by-step explanation:

Given

[tex]Length = 10[/tex]

[tex]Width = 3[/tex]

[tex]Height = 4\frac{1}{2}[/tex]

Required

The surface area

This is calculated as:

[tex]Area = 2 * (Length * Width + Length * Height + Width * Height)[/tex]

So, we have:

[tex]Area = 2 * (10* 3+ 10* 4\frac{1}{2}+ 3* 4\frac{1}{2})[/tex]

[tex]Area = 2 * (30+ 45+ 13\frac{1}{2})[/tex]

[tex]Area = 2 * (88\frac{1}{2})[/tex]

[tex]Area = 177[/tex]

A sample of restaurants in a city shows that the average cost of an appetizer is $6.32 with a standard deviation of $0.47.

Step-by-step explanation:

By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.

Option B is the correct answer.

What is a standard deviation?

Standard deviation is a measure of the amount of variability or spread in a set of data.

It is calculated as the square root of the variance and is often denoted by the symbol σ (sigma) for a population and s for a sample.

We have,

The z-value formula is used to determine the number of standard deviations a data point is from the mean.

To determine the lower price of appetizers, we want to find a price that is significantly lower than the average cost.

Since the new restaurant wants to offer appetizers for a much lower price, we should use a z-value that is less than -1, which indicates a price that is more than one standard deviation below the mean.

Recall that the z-value formula is:

z = (x - μ) / σ

where x is the value of interest, μ is the mean, and σ is the standard deviation.

Thus,

By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.

Answer:

7- 780 m

8- 9,459 cm

9- 864 cm

10- 151 in

Step-by-step explanation:

7- The volume of a rectangular pyramid is:

V=(l x w x h) / 3

We just have to substitute the values:

V= 13×12×15 / 3V= 780 m

8- The volume of a cone is:

V=hπr² / 3

Let's substitute the values and solve:

24×π×19.4² / 39,458.9

If you want to round it, the answer will be:

9,459 cm

9- The volume of a square pyramid V = a²h / 3, where a is the base and h the height.

So,

V= 12²×18 / 3864 cm

10- The volume of the cone is V = hπr² / 3

Then,

V= 16×9×π / 3

9 is the diameter, which is the radius two times. As you see, what the formula asks is for the radius at the second power -multiplied by itself two times-, but if we get the diameter value instead, there is no need to multiply it. The diameter stays the same.

V= 150.7

If you want to round it to the nearest tenth, the answer is:

151 in.
