The ratio of destroyers to battleships in the navy is 20:15. If the total number of boats is 105, how many battleships are there?

Answers

Answer 1

Answer:

45

Step-by-step explanation:

20:15 the ratio can be turned to a fraction

20/15

simplify

4/3

so now add the numerator and the denominator and get 7

then do 105/7=15

and then you do

4x15=60 (Destroyers)

3x15=45 (Battleships)

45 is your answer

2. A submarine dives 60 meters in 5 minutes. Find how quickly it dives in feet per second (recall 1 meter = 3.28084 feet). How many feet can it dive in 6 minutes and 34 seconds?

Answers

Answer:

258.54 feet

Step-by-step explanation:

Step 1

We convert 60 meters to feet

1 meter = 3.28084 feet

60 meters = x

Cross Multiply

x = 60 × 3.28084 feet

x = 196.8504 feet

60 meters = 196.8504 feet

Step 2

How many feet can it dive in 6 minutes and 34 seconds

We convert 34 seconds to minutes

60 seconds = 1 minute

34 seconds = x

Cross Multiply

60 × x = 34 × 1

x = 34/60

x = 0.567 minutes

So, 6 minutes and 34 seconds = 6 + 0.567 minutes = 6.567 minutes.

60 meters in 5 minutes.

60 meters = 196.8504 feet

Hence:

5 minutes = 196.8504 feet

6.567 minutes = x

Cross Multiply

5x = 6.567 × 196.8504 feet

5x = 1292.7165768 feet

x = 1292.7165768/5

x = 258.54331536 feet

Approximately = 258.54 feet

Therefore, the submarine can dive 258.54 feet in 6 minutes 34 seconds

Answer:

A) 130°

Step-by-step explanation:

Angle UTV = angle YTX = 75°

Angle VTW = 55°

so UTW = 75 + 55

if this helps, please give brainliest if possible

Answer:

A

Step-by-step explanation:

∠ UTV = ∠ YTX = 75° ( vertically opposite angles )

∠ VTW = 55° ( angle at centre is equal to arc that subtends it )

Then

∠ UTW = ∠ UTV + VTW = 75° + 55° = 130° → A

42.Anna pours herself some room-temperature soda from a bottle and adds four ice cubes. In a few minutes the ice cubes are smaller and the soda is much colder. Which of the following best explains the change in temperature of the soda?



A. Heat flowed from the soda to the ice cube and caused it to partially melt.

B. Coldness flowed from the ice cube to the soda, making the soda cooler.

C. The cold water from the melting ice went into the soda, replacing the warmer water that was in the soda

D. The water from the melting ice makes the soda more dilute, and the lower concentration makes the temperature lower.

and send me link for explenation

Answers

Answer:

Option A

Step-by-step explanation:

According to the second law of thermodynamics, heat always flows from hot to cold places, unless work is done on the system. In this case the ice is colder than room temperature, and therefore the heat flows from the soda to the ice cube. The ice cube absorbs the heat, and partially melts.

A line segment has endpoints F(2, 2) and G(8, 2) Find the coordinates of its midpoint M

Answers

Answer:

(5,2)

Step-by-step explanation:

The midpoint of a line segment is calculated by finding the average of the x values and the average of the y values of the endpoints.

[tex]midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )[/tex] when the points given are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug points F(2,2) and G(8,2) into the equation

[tex]midpoint=(\frac{2+8}{2},\frac{2+2}{2} )\\midpoint=(\frac{10}{2},\frac{4}{2} )\\midpoint=(5,2)[/tex]

Therefore, the midpoint of the line segment with endpoints F and G is (5,2).

Find the surface area.
13.5 in
9 In
9 in.
10 in.

Answers

the surface area of the body is approximately 739.72 square inches. first find the area of the two triangles (base and top) using Heron's formula

what is surface area ?

Surface area is the total area of all the faces or surfaces of a three-dimensional object. It is the sum of the areas of all the faces of the object, including the top, bottom, and sides. Surface area is usually measured in square units, such as square inches or square meters.

In the given question,

Let's first find the area of the two triangles (base and top) using Heron's formula:

For the base triangle with side lengths 9, 10, and 13.5:

s = (9 + 10 + 13.5)/2 = 16.25

Area = √(s(s-9)(s-10)(s-13.5)) = 35.44 square inches

For the top triangle, the side lengths are the same, so the area is also 35.44 square inches.

Now, let's find the area of the four sides. We can divide the body into two trapezoids and two triangles. The trapezoids have heights of 9 inches and bases of 9 and 10 inches. The triangles have a base of 13.5 inches and a height of the slant height of the trapezoid, which we can find using the Pythagorean theorem:

h = √(13.5² - (10-9)²) = √(146.25) = 12.1 inches

So, the area of each trapezoid is:

(9/2)*(9+10)*√(146.25 - 9.5²) = 252.28 square inches

And the area of each triangle is:

(1/2)13.512.1 = 81.94 square inches

Finally, the total surface area is the sum of all these areas:

35.44 + 35.44 + 252.28 + 252.28 + 81.94 + 81.94 = 739.72 square inches

Therefore, the surface area of the body is approximately 739.72 square inches.

solve 2x+6=34 i have no idea pls exsplain and help me :)

Answers

You want to try to isolate the x:
First subtract 6 from both sides so you get 2x=28

Then divide both side by 2 so you get x=14 which is your answer :)

ANSWER: x=14

Answer:

14

Step-by-step explanation:

okay.. so basically you have 2x+6=34 right? so basically i’m gonna tell you the easiest way to do this

so you’re gonna start off by separating the 2x from the 6=34.

now that you’ve done that, let’s focus on the 6=34. so to get your answer, start by subtracting 6 from 34 so (34 - 6 = 28)

now that you’ve got that, keep the number 28 in mind. youre gonna want to take 2 and multiply by x. but 2x = 28, so what do you multiply by 2 to make 28? 14. so x is 14. to check your work, let’s see.

2 x 14 + 6 = 34?

2 x 14 = 28 + 6 = 34.

34 = 34

so, x is 14. hope this helped!

Find the Circumference area of the circle. Use 3.14 for pi. Round tithe nearest hundredth if necessary

Answers

Answer:

351.68cm

Step-by-step explanation:

Using the attached diagram

Radius of the circle = 56cm

Circumference of the circle =2πr

r is the radius of the circle

Circumference of the circle =2(3.14)(56)

Circumference of the circle = 6.28 *56

Circumference of the circle  = 351.68cm

Hence the circumference area of the circle is 351.68cm

Answers

Answer:

26, 64

Step-by-step explanation:

we have :

angle 90°

acute angle x

acute angle 2(x+6)

The sum of the angles in a triangle has to be 180° so

90 +x+2(x+6) = 180

90 +x +2x+12 = 180

3x = 180 -90-12

x= 78/3 = 26°

the other acute angle is 2(26+6) = 64°

Answer:

26, 64

Step-by-step explanation:

We can name the first acute angle x and the second acute angle y. We know that x=2(y+6) but we also need another equation to solve the problem. Since we know that the sum of angles in a triangle is equal to 180 degrees and this is a right triangle, the two acute angles sum will be equal to 90 degrees. That would be our second equation, x+y=90. Now we can just substitute the first equation into the second one: 2(y+6)+y=90 -> 2y+12+y=90 ->3y=78 -> y=26

Now we can substitute y into one of the original equations and solve for x: x+26=90 -> x=64
