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?
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

You can buy jars of the same jam in two sizes.
Large Jar
Small Jar
440g for £1.54
340g for £1.26
By considering the price per gram, work out
which jar is the best value for money.
Answer:
large jar
Step-by-step explanation:
large jar= £1.54 (divide) 440= 0.0035
small jar= £1.26 (divide) 340= 0.0037
as the large jar cost less (0.0035 > 0.0037) the large jar is the best value for money

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

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

Solve for the measure
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

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

solve 2x+6=34 i have no idea pls exsplain and help me :)
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 surface area.
13.5 in
9 In
9 in.
10 in.
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.
