Down refers to the movement along the y axis and left and right refer to movement along the x axis. 20. down 2, no y movement 21. 5 to the left, no y movement 22. to the right 1, no y movement 23. 4 to the left, down 3 24. to the left 2 and up 2 25. 4 to the right and down 9 26. opens up a bit wider, no x or y movement (picture it opening like a flower blooming) 27. opens downward and is very very close to the y axis 28. opened up SUPER wide, like a large shallow bowl.

PLEASE HELP! The trail around Mirror Lake in Yosemite National park is 5 miles long. What fraction describes how much more of th

Katen [24]

Answer:

Jon - Andrea = 1/10
Callie - Jon = 3/10

Step-by-step explanation:

In terms of tenths, the distances each hiked are ...

Andrea — 4/10
Jon — 5/10
Callie — 8/10

Then the differences of interest are ...

Jon - Andrea = 5/10 -4/10 = 1/10

Callie - Jon = 8/10 - 5/10 = 3/10

Jon hiked 1/10 of the trail more than Andrea.

Callie hiked 3/10 of the trail more than Jon.

A farmer can buy two types of plant food, mix A and mix B. Each cubic yard of mix A contains 35 pounds of phosphoric acid, 15

Nadusha1986 [10]

Answer:

The answer is below

Step-by-step explanation:

Given that the minimum monthly requirements are 840 pounds of phosphoric acid, hence:

35 pounds of phosphoric acid mix A + 14 pounds of phosphoric acid mix B ≥ 840 pounds of phosphoric acid

35x + 14y ≥ 840

The minimum monthly requirements are 540 pounds of nitrogen, hence:

15 pounds of nitrogen mix A + 18 pounds of nitrogen mix B ≥ 540 pounds of nitrogen

15x + 18y ≥ 540

The minimum monthly requirements are 768 pounds of potash, hence:

16 pounds of potash mix A + 64 pounds of potash mix B ≥ 768 pounds of potash

16x + 64y ≥ 768

Also, x ≥ 0 and y ≥0.

Therefore the equations are:

35x + 14y ≥ 840

15x + 18y ≥ 540

16x + 64y ≥ 768

x ≥ 0 and y ≥ 0

Plotting with geogebra gives the graph below.

a metal worker has a metal alloy that is 20% copper, and another metal alloy that is 60% copper. How many kilograms (kg) of each

emmainna [20.7K]

Let X = the 29% alloy and Y = the 60% alloy.

They want a total of 80kg, so you have X +Y = 80

Rewrite that to get X = 80-Y

You also want 0.20X + 0.60Y = 0.52(80)

Replace X with 80-y:

0.20(80-y) + 0.60y = 0.52(80)

Simplify:

16 - 0.20y + 0.60y = 41.6

Combine like terms:

16 +0.40y = 41.6

Subtract 16 from each side:

0.40y = 25.6

Divide both sides by 0.40

y = 25.6 / 0.40

y = 64

Now you have Y replace y with 80 in X = 80-Y

X = 80 - 64

X = 16

They need 64 Kg of the 60% alloy and 16 Kg of the 20% alloy.
