11. A scuba diver's elevation changed by -123 feet every minute. This was
1½ times the rate of change for a second scuba diver. What was the rate of
change in elevation of the second scuba diver in feet per minute?

Answers

Answer:

The rate of change in elevation for the second scuba diver is -82 feet per minute.

Step-by-step explanation:

-123 feet every minute.

1.5x more than 2nd diver.

-123/1.5 = 2nd diver rate

2nd diver rate = -82

The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Given that, a scuba diver's elevation changed by -123 feet every minute.

What is constant rate of change?

When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half  hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.

1½=1.5 times the rate of change for a second scuba diver

Now, rate of change in elevation of the second scuba diver

= -123/1.5

= -82 feet per second

Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Since the area is equal to length times width, and you know your area has to be 30, you can plug in your values like this:

(2x+7) x = 30

you can distribute to make this easier

2x^2 + 7x = 30

you can plug this into quadratic formula by setting the equation =0, so:

2x^2 +7x -30 = 0

where 2x^2 = a
7x = b
and -30 = c

you can plug this into your calculator and get an answer of

What is the area of the rhombus?

16.75 cm2
33.5 cm2
139.5 cm2
279 cm2

Answers

Answer:279 cm²Step-by-step explanation:

Formula used,

Area of rhombus = Base × height

Substituting the values,

\( \longrightarrow\)Area = 18 × 15.5

\( \longrightarrow\) Area = 279 cm²

Therefore, 279 cm² is the area of the rhombus .

Answer:

D) 279 cm²

Step-by-step explanation:

Area of a rhombus formula:
\(A=bh\)

This formula is also used for squares and rectangles.

So, we can substitute in our values such as:

A=(18)(15.5)

simplify

A=279

Now, add our label and units:

A=279 cm²

Solve this addition question by substituting numbers for the given letters to find the value of START. Each letter represents a unique digit.

JOAN+CAN=START

Answers

Solved the given question by addition rules and the value of START is 10430.

Given-

The given problem is from the alphabetical puzzle. In the given problem the equation given is,

JOHN + CAN = START.

It can be written as,

   J  O  H  N

+      C  A  N

__________

S  T  A  R  T

__________

S must be 1, because, even if we assume all the missing digit are 9 ( the largest possible value), the sum will be smaller than than 10999 or equal to the 10998.

Similarly the value of T must be 0 because, even if we assume all the missing digit are 9 ( the largest possible value), the sum will be smaller than than 10999 or equal to the 10998.

Now as the T is two times in the solution of addition, and the value of T is 0 as we found. But T is the addition of N and N. Hence N must be 5 to make the addition 10 for the 0 value of the T.

                N

            +  N

            ____

              1 0

            ____

J must be 9 with carried 1 to make the T 0.

A must be more than 10 to have a carry on J. A can not 1 as S has 1 digit. 2 and 3 disturbs the equation. Thus a must be 4. and for this o and c must be 6 and 7.

If a is 4 than the H and R must be 8 and 3.

The sum will look like,

A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers.

When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.

Answers

Answer:

A. The students tend to have fewer siblings than the teachers.

Step-by-step explanation:

First we need to draw the dot plots correctly. If you count both sides they have 20 each.

Now, clearly none have fewer nobody here yet has more or less but going on to the next step.

Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14.  And so on.

On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.

So the answer is A. The students tend to have fewer siblings than the teachers.
