A. evaporation
B. precipitation
C. condensation
D. runoff

Answers

Answer:

evaportation

Step-by-step explanation:

The vapor given off by water, plants, and animals is called evaporation.

What is evaporation?Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water.

Given is to find what does the water vapor given off by water, plants, and animals is called.

Evaporation is defined as the conversion of water into water vapour (into gas phase) and its release into the atmosphere. Similarly, the Water vapor given off by water, plants, and animals is called evaporation.

Therefore, the vapor given off by water, plants, and animals is called evaporation.

Answer:

length = 3√5

distance = √13

Step-by-step explanation:

length = √[(lenght(1,-2)to(4,-2))² + (length(4,-2)to(4,4))²]

length = √ 3²+6²

=√9+36

=√45=3√5

distance

d = √(x1-x2)²+(y1-y2)²

d= √(5-3)² + (-2-1)²

d=√2²+(-3)²

Howe Moving Company has a loading ramp for their moving truck. The ramp connects to the truck 5 feet above the ground, and the length of the ramp from the truck to the ground is 13 feet long. What is the distance along the ground from the truck to the end of the ramp?

Answers

Answer:

12 feet

Step-by-step explanation:

Given that,

The ramp connects to the truck 5 feet above the ground, and the length of the ramp from the truck to the ground is 13 feet long.

Now we need to find the distance along the ground from the truck to the end of the ramp.

Here,

5 feet will be perpendicular distance, 13 feet will be hypotenuse and we need to find the base.

Using Pythagoras therorem to find it :

[tex]b=\sqrt{13^2-5^2} \\\\=12\ \text{feet}[/tex]

So, the required distance is 12 feet.

Answer:

12 feet!!

1+3k<-4+3k        Subtract -3k on both sides (it's less confusing when you get

  -3k      -3k        rid of the variable first).

Answers

Answer: 225 adult tickets, 375 student tickets

Step-by-step explanation:

a = adult tickets

s = student tickets

a + s = 600 (the adult and student ticket added together should equal 600)

6.00a + 4.50s = 3,037.50 ($6 multiply by the adult ticket plus $4.50 multiply by the student ticket should equal to 3,037.50)

a = -s + 600 (get one of the variable by itself by subtracting it from one side)

6 (-s + 600) + 4.5s = 3,037.5 (substitute the a for -s + 600)

-6s + 3600 + 4.5s = 3,037.5 (combine like terms)

-1.5s + 3600 = 3,037.5 (subtract 3600 from each side)

-1.5s = - 562.5 (divide -1.5 from each side)

s = 375

600 = 375 + a (substitute s for 375)

a = 225

A school board voted whether to adopt new math books. Those that voted yes
out numbered those that voted no by a ratio of 5 to 1. If 18 school board
members voted, how many voted yes for new math books and how many
voted no?

Answers

Answer:

15 people voted yes and 3 people voted no.

Step-by-step explanation:

Given that:

Ratio of yes to no = 5 : 1

Total number of board members who voted = 18

Let,

x be the number of times.

5x+x = 18

6x = 18

Dividing both sides by 6

[tex]\frac{6x}{6}=\frac{18}{6}\\x=3[/tex]

People who voted yes = 5(3) = 15

People who voted no = 3

Hence,

15 people voted yes and 3 people voted no.

Expand and simplify

Answers

Answer: 3x^2 − 11x − 42

Step-by-step explanation:

Simplify  (x − 6) (3x + 7)

Expand (x − 6) (3x + 7) using the  FOIL Method.

Apply the distributive property.

  x (3x + 7) − 6 (3x + 7)  

Apply the distributive property.

  x (3x) + x ⋅ 7 − 6 (3x + 7)

Apply the distributive property.

  x (3x) + x ⋅ 7 − 6 (3x) − 6 ⋅ 7

Simplify and combine like terms.

Rewrite using the commutative property of multiplication.

  3x ⋅ x + x ⋅ 7 − 6 (3x) − 6 ⋅ 7

Multiply x by x by adding the exponents.

Move x.

  3 (x ⋅ x) + x ⋅ 7 − 6 (3x) − 6 ⋅ 7

Multiply x by x.

  3x^2 + x ⋅ 7 − 6 (3x) − 6 ⋅ 7

Move 7 to the left of x.

  3x^2 + 7 ⋅ x − 6 (3x) − 6 ⋅ 7

Multiply 3 by −6.

  3x^2 + 7x − 18x − 6 ⋅ 7

Multiply −6 by 7.

  3x^2 + 7x − 18x − 42

Subtract 18x from 7x.

  3x^2 − 11x − 42


(x-6)(3x+7)
= 3x^2 + 7x - 18x - 42
= 3x^2 - 11x - 42

FAST ILL MARK U BRAINLIEST Write an equation of the line that passes through (2, −1) and is parallel to the line 2y + 3x = 8 . Write your answer in slope intercept form.

Answers

Answer:

y=[tex]-\frac{3}{2}[/tex]+2

Step-by-step explanation:

for an equation to be parallel with another both should have the same rate of change(m).

the line given to us is in general form, and we can change it to slope-intercept form to get the slope. (y=mx+b)

Isolate for y:

2y+3x=8

2y=-3x+8

y=-3/2x+8/2

y=-3/2x+4

thus the slope of the line we are trying to find must also equal -3/2

use point slope form to find the equation (substitute (2, -1) into equation)

y-y1=m(x-x1)

y-(-1)=(-3/2)(x-2)

y+1=[tex]-\frac{3}{2}[/tex]x+3

y=[tex]-\frac{3}{2}[/tex]+2

Select the equation that is true.
