BIG JIM/LITTLE JIM PROBLEM When Big Jim stands on a bench that is 15 inches high, the top of his head is 53 inches above the top of Little Jim’s head. Big Jim’s height is twice that of Little Jim’s height. How tall is Big Jim? How tall is Little Jim?

Answers

Answer:

Let J = height of Little Jim. Then Big Jim's height is 2J.

when big jim stands on a bench that is 15 inches high, the top of his head is 53 inches above the top of little jims head.

The above given sentence means 15+ 2J= J+53.

15+2J = J+53

2J-J = 53-15

J = 38 inches

Solve the system of equations
the equations.

Answers

Answer:

y = 9.54

and, x = 0.08

Step-by-step explanation:

Given that

x - 2y = -19 .......................(1)

3x + 5y = 48 ...............(2)

Based on the above information

Multiply by 3 in equation 1

So,

3x - 6y = -57

3x + 5y = 48

-     -        -

-11y = -105

y = 9.54

So, the x would be

x - 2(9.54) = -19

x - 19.08 = -19

x = -19 + 19.08

x = 0.08

You plant a tree that is 36 inches tall. After one year, the tree is 43 inches tall. Which expression describes the percent of increase in the tree's height? 3643×100 43−3643 43−3636×100 43−3643×100

Answers

Answer:

19.4%

Step-by-step explanation:

Given data

Initial height=36in

Final height= 43in

% increase= Final-initial/initial*100

Substitute

% increase= 43-36/36*100

%increase= 7/36*100

%increase= 0.194*100

%increase= 19.4%

Hence the increase is 19.4%

Answer:

40 cm³

Step-by-step explanation:

The information we have about the volume of Prism Y is only that it is 10 cm³ greater than the volume of Prism X. So, we have to first find the volume of Prism X.

The volume of a rectangular prism is found by multiplying the length, width, and height of the figure. X has dimensions of 2 × 5 × 3, so we will multiply these together.

2 · 5 · 3 = 30

The volume of prism X is 30cm³.

Prism Y is 10 cm³ greater than this.

30 + 10 = 40

Prism Y has a volume of 40 cm³.

Solve for y: 5(y + 2/5) = -13

Answers

The answer is y= -3

Hope this help

Answer:

y = -3

Step-by-step explanation:

Let's solve your equation step-by-step.

5 (y+2/5) = −13

Step 1: Simplify both sides of the equation.

5(y+2/5)= −13

(5)(y) + (5)(2/5) = −13(Distribute)

5y + 2 = −13

Step 2: Subtract 2 from both sides.

5y + 2 − 2 = −13 −2

5y = −15

Step 3: Divide both sides by 5.

5y/5 = −15/5

y = −3

Answer:

y = −3

A broad expanse of the river wasturned to blood; in the middle distance the red hue brightened into gold, through which a solitary log came floating black and conspicuous; in oneplace a long, slanting mark lay sparkling upon the water, in another the surface was broken by boiling, tumbling rings, that were as many-tinted asan opal, where the ruddy flush was faintest, was a smooth spot that was covered with graceful circles and radiating lines, ever so delicately traced;the shore on our left was densely wooded, and the sombre shadow that fell from this forest was broken in one place by a long ruffled trail thatshone like silver, and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructedsplendor that was flowing from the sun.....The world was new to me, and I had never seen anything like this at home. But as I have said, a day came when I began to cease from notingthe glories and the charms which the moon and the sun and the twilight wrought upon the river's face, another day came when I ceased altogetherto note them. Then, if that sunset scene had been repeated, I should have looked upon it without rapture, and should have commented upon it,inwardly, after this fashion. This sun means that we are going to have wind to-morrow, that floating log means that the river is rising small thanksto it that starting mark on the water refers to a bluff reef which is going to kill somebody's steamboat che of these nights, if it keeps on stretchingout like that, those tumbling "bolls" show a dissolving bar and a changing channel there, the lines and circles in the slick water over yonder are awarring that the troublesome place is shoaling up dangerously,Which statement best conveys how the author's viewpoint changes in the passage?1.
