A.The graph is a straight line.

B.The line passes through the origin.

C.The line passes through the point (0, –2)(0, –2) .

D.The slope of the line is 3.

E.The y-intercept of the line is 2.

Answers

Answer 1

Answer:

The correct statements regarding the line y = (1/3)x - 2,

A. The graph is a straight line.

C. The line passes through the point (0, - 2) .

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, An equation of a line y = (1/3)x - 2.

The correct statements are,

The graph is a straight line.

The line does not pass through the origin at, when x = 0, y = - 2.

Now, for x = 0, y = - 2 so, The line passes through the point (0, - 2).

A traveller found himself in a strange country where the temperature rose sharply during the day and then fell again at night and made his watch act erratically. He noticed that his watch was 30 seconds fast at nightfall but at dawn it had lost 20 seconds. On the morning of May 1st the watch showed the right time.By which date was it five minutes fast?

Answers

Wow ! This could be a real limbic tickler.
Let's try to find an easy way to do it . . .

If the watch is 30 seconds ahead at bedtime, and then it loses 20 of them
overnight, then from one morning to the next morning, it pulls ahead by
10 seconds.

So every morning, the watch is 10 seconds farther ahead than it was on
the previous morning.

That's the last time you have to worry about what it reads at night, or
what it loses overnight ! Just remember . . . 10 seconds farther ahead
every morning.
============================================

Now, how many times does it have to gain 10 seconds in order to add up
to 5 minutes ?

-- 10 seconds is (10/60) = 1/6 of a minute. So from one morning until
6 mornings later, the watch gains (6 x 1/6) = 1 whole minute.

-- And from one morning until (5 x 6) = 30 mornings later, it gains
(5 x 1) = 5 minutes.

The watch was correct on the morning of May 1. It gained 10 more seconds
every morning after that.

-- It was 1minute ahead on the morning of May (1 + 6) = 7.
-- It was 2 minutes ahead on the morning of May (7 + 6) = 13.
-- It was 3 minutes ahead on the morning of May (13 + 6) = 19.
-- It was 4 minutes ahead on the morning of May (19 + 6) = 25.

And it was 5 minutes ahead on the morning of May 31.

Which container has the greatest surface area? (Use 3.14 for π .)cone
cylinder
square pyramid
rectangular prism

Answers

Answer:

the cylinder container has the greatest surface area.

Step-by-step explanation:

The volume of cone is calculated by $v=(1)/(3)*\pi* r^(2)* h$

The volume of cylinder is calculated by $v=\pi* r^(2)* h$

The volume of square pyramid is calculated by $v=\pi* r^(2)* h$

The volume of rectangular prism is calculated by $v=(1)/(3)* B* h$

The radius of cone is $(6)/(3)$ = $2in$ , and slant height is 10 in.

height is calculated as h² = l²- r²

h² = l²- r²

h² = 10²- 3²

h² = 100- 9

h² =91

h= 9.54

The volume of cone is $=(1)/(3)* 3.14* 3^(2)* 9.54$

$=(1)/(3)* 3.14* 9* 9.54$

v=89.8668

The volume of cylinder is $=3.14* 3^(2)* 10$

$=3.14*9* 10$

v=282.6

The volume of square pyramid

The height of pyramid is calculated as h² = l²- r²

h² = 10²- 3²

h² = 100- 9

h² =91

h= 9.54

$v=3.14* 3^(2)* 9.54$

$v=3.14* 9* 9.54$

$v=269.60$

The volume of rectangular prism $v=(1)/(3)* 6* 10$

$v=20$

Hence, the cylinder container has the greatest surface area.

Answer:

It is the Rectangular Prism.

88% of what number is 66? A.
75

B.
58.08

C.
1.3

D.
0.75

Answers

let the unknown number be x
88% * x= 66 (divide both sides by 88%)
x= 66/88%
x= 75
Therefore the answer is A) 75

if the unknown number be x, then
88 multiply x is 66
then we need divide both sides by 88
x = 66 : 88
x = 0.75
Now we need 0.75 multiply 100(%) and we get 75
Therefore the answer is

A) 75
