Step-by-step explanation:

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.

Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.

On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.

What is the elevation of the deck where Winston ate dinner?

Step-by-step explanation:

So far this year, Adam has played 30 games of chess and has only won 6 of them. What is the minimum number of additional games he must play, given that he is sure to lose at least one-third of them, so that for the year he will have won more games than he lost?
A) 24
B) 57
C) 87
D) It is not possible for Adam to do this.

The correct answer is B) 57, but not sure how?

Answers

Answer:

Step-by-step explanation:Yikes. Just so we’re all clear—this is not a real SAT question.

So far, Adam’s record is 6 wins/30 games. If he plays x more games, his record will be:

image

You find the minimum x such that the fraction is greater than ½, which would mean he won more than ½ of his games.

Let’s do some math!

image

So if he plays 54 more games, and wins 2/3 of them, he’ll have the same number of wins as losses. Check on that to make sure: He’ll have played 30 + 54 = 84 games, and won 6 + (2/3)54 = 42 of them. Yep, that works.

Now here is where it gets tricky (and why this question is not SAT-caliber). Remember that he’s losing 1/3 of his games. If his 52nd, 53rd, and 54th additional games were win, win, loss, then he would have had, very briefly, a winning record after his 53rd additional game.

His 55th additional game is another chance at a winning record. If he loses that game, then he’ll win the next two, and have a winning record for sure by the 57th additional game. From there, if he continues winning 2/3 of his games, he’ll have a winning record forever.

Try adding 57 to the equation, then you can see how 57 adds into the equation and proves the answer.

H=16 L1=3 L2=2

Step-by-step explanation: First, we need to brainstorm the multiples of 32 and 48, 16 comes to mind. Because 48 and 32 are both multiples of 16, one can determine that since 16x3 is 48 then L1, should be 3. Finally 16x2 is 32 so L2 must be 2.

Answer: 48 + 32 = 16 (3+2)

Step-by-step explanation:

Find the area of the whole rectangle:

48 + 32 = 80

Now things are more easier!

let's just say that the length is 5 broken up and the height is 16

16 x 5 = 80

All we need to do is break it up correctly to fit make the totals 48 and 32.

16 x 3 = 48

16 x 2 = 32

In the end we get the equation:

48 + 32 = 16 (3+2)

Step-by-step explanation:

Slope intercept from has 4 parts, a y, an x, an m, (slope in front of x) and a b (y-int).

We must first isolate the 1y to the front of the equation by adding 1x to each side.

What is the account balance if $1,750 is deposited at a simple annual interest rate of 5.75% for 9 months?

What is the account balance if $1,750 is deposited at a simple annual interest rate of 5.75% for 9 months?

Answers

Answer:

$1,825.47

Step-by-step explanation:

To find the account balance after 9 months of depositing $1,750 at a simple annual interest rate of 5.75%, we need to use the formula:

Simple Interest = P * r * t

where P is the principal amount, r is the interest rate, and t is the time period.

First, we need to convert the annual interest rate to a rate for 9 months. We can do this by dividing the annual rate by 12 and multiplying by 9:

Interest rate for 9 months = (5.75%/12) * 9 = 4.3125%

Now we can substitute the values into the formula and solve for the simple interest:

Simple Interest = $1,750 * 4.3125% * (9/12)

Simple Interest = $70.90

The simple interest is $70.90, which means the account balance after 9 months is:

Account balance = $1,750 + $70.90

Account balance = $1,820.90

Therefore, the correct answer is option 3, $1,825.47 (rounded to the nearest cent).

Firstly, you have to find the area of the whole shape. After that, you subtract that from the area of the individual triangle to get your answer.

The whole shape is a rectangle, with a length of 6 and a width of 7.
To find the area, multiply 6 by 7=42yd^2

The area of the entire shape is 42yd^2

Now, the vertical 4yd side plus the height of the dotted triangle will equal 6yd.
So the height of the dotted triangle is 6-4=2yd.

The horizontal 4yd side plus the base of the dotted triangle will equal 7yd.
So the base of the dotted triangle is 7-4=3yd.

Formula for area of triangle: 1/2 x base x height
1/2 x 4 x 3= 6yd^2

The area of the dotted triangle is 6yd^2

Now subtract the area of the whole shape by the area of the dotted triangle to get the shaded region.

42-6= 36yd^2

Area of shaded region: 36yd^2 (i think)

Number =  0.1515

This can be expressed as

Number =  0.15

Express as fraction

So, we have

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

the area of the five squares is 1289.09 square units

the perimeter is 194.6 units
