Answer:

5.5 meters above start position.

Step-by-step explanation:

-Let X be the start position.

#Total distance below the start position is calculated as:

$d_{down}=6+5.5\times 7\\\\=44.5\ m$

#Total distance above the start position X:

$d_{up}=50\ m$

#Distance above/below start position is:

$d=X-d_{down}+d_{up}\\\\=X-44.5+50\\\\d=X+5.5\ m$

Hence, The vessel is 5.5 meters above the start position

6 is added to the product of 7 and a number

notka56 [123]

The value of the expression will be equal to 55.

<h3>What is an expression?</h3>

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that 6 is added to the product of 7 and a number 7. The expression will be written as,

E = 7 x 7 + 6

E = 49 + 6

E = 55

Therefore, the value of the expression will be equal to 55.

What is the coefficient of the second term of the trinomial?

marin [14]

The coefficient of the second term is 18.

What you do is you FOIL the terms:
$(3x+3)(3x+3)\\ Multiply\ the\ first\ terms\ together:\\ 3x*3x=9x^{2}\\ Then\ the\ outer\ terms:\\ 3x*3=9x\\ Next,\ the\ inner\ terms:\\ 3x*3=9x\\ Finally,\ multiply\ the\ last\ terms:\\ 3*3=9\\ Putting\ the\ terms\ together:\\ 9x^{2}+9x+9x+9=9x^{2}+18x+9\\\\ Since\ (3x+3)^{2}=9x^{2}+Bx+9=9x^{2}+18x+9,\ then \ B=18.$

Try this X varies directly as y and jointly as z, and x = 20, when y=3 and z= 4 a. Find the constant b. What is the formula conn

Viktor [21]

Answer:

Step-by-step explanation:

as x is direct to y hence

x∝y

also given x∝z combine these two equation we get

x∝y*z

now insert b as constant

x=b*y*z

as given x=20, y=3 , z=4 putt in above equation we get

b=20/3*4 =5/3 =1.666

a pack rat has 130 piglets and 110 books. She wants to maintain this ratio in her collection but needs to sell some of her items

bija089 [108]

The number of items she should sell from her collection is 24

<h3>How to determine the number of items she should sell from her collection?</h3>

From the question, we have the following parameters that can be used in our computation:

Ratio = Piglets : Books

For 130 piglets and 110 books, we have the following representations

Ratio = 130 : 110

Also, for 13 piglets, we have the following representations

Ratio = 13 : Books

Using the above as a guide, we have the following:

13 : Books = 130 : 110

This can also be rewritten as

Books : 13 = 110 : 130

Multiply the second ratio by 1/10

So. we have

Books : 13 = 11 : 13

By comparison, we have

Books = 11

So, the total items sold is

Items = 11 books + 13 piglets

Evaluate

Items = 24 items

Hence, the number of items is 24
