In the state of New Mexico, 85% of the land is above 4,000 feet in elevation.
Which fraction is equivalent to 85%?
A) 4/5
B) 5/8
C) 17/20
D) 1/85

Answers

Answer:

85 % = 17/20

Step-by-step explanation:

It is given that,

85% of the land is above 4,000 feet in elevation.

We need to write a fraction that is equivalent to 85%.

We know that, percent means dividing by 100 i.e.

[tex]85\%=\dfrac{85}{100}[/tex]

We can write 85 as 17×5 and 100 as 20×5

So,

[tex]\dfrac{85}{100}=\dfrac{17\times 5}{20\times 5}[/tex]

5 will cancel out from numerator and the denominator

[tex]\dfrac{85}{100}=\dfrac{17}{20}[/tex]

Hence, the correct option is (c).

Suppose m <6= 147º. Find <1 and m<3

Answers

Answer:

∠ 1 = ∠ 3 = 33°

Step-by-step explanation:

∠ 3 and ∠ 6 are same- side interior angles and are supplementary , thus

∠ 3 + ∠ 6 = 180° , that is

∠ 3 + 147° = 180° ( subtract 147° from both sides )

∠ 3 = 33°

∠ 1 and ∠ 3 are vertical angles and congruent, thus

∠ 1 = ∠ 3 = 33°

If angle J and angle K are vertical angles, J and K are congruent.

Which of the following rules could represent the function shown in the table?
f(x) = -2x
f(x) = 2x-1
f(x) = 2x+1

Answers

Answer: f(x) = 2x+1

Step-by-step explanation: Substitute the variable with the “x” values in the chart to check your answers.

1. f(x) = 2x+1

Add in the “x” value

f(x) = 2x(-1) or 2 multiplied by -1

f(x) = -2 + 1

If the answer is equal to your “y” value , it can represent the function.

Answer:

function: (1, 98), (2, 98), (3, 2), (4, -86)not a function: (1, 98), (2, 98), (3, 2), (3, -86)

Step-by-step explanation:

A relation that is a function has unique x-values. A relation that is not a function has at least one x-value that is repeated. The y-values do not need to be unique in either case, except that a repeat of the same (x, y) pair does not disqualify a relation from being a function.

In the table shown above, the non-function has the x-value of 3 repeated with different y-values.

What is an eqination of the line that passes through the point (-3, -7) and parallel to the line 3x-y=5
I need the y=mx+b

Answers

Answer:

y = 3x + 2

Step-by-step explanation:

First you need to change the way the equation is said into a easier form:

y = 3x - 5

Since the line is parallel, you can use the same slope of 3:

y = 3x + b

Now you plug in the coordinates into the equation and solve for b:

-7 = 3 ( -3) + b

-7 = - 9 + b

-7 + 9 = b

2 = b

Now plig this into the equation and you have the answer

y = 3x + 2

solve for x in terms of y: 5y = 3x + 2

Answers

Answer:

d. x = 1/3 (5y - 2)

Step-by-step explanation:

5y = 3x + 2 (subtract 5y and 3x on both sides)

-3x = -5y + 2 (divide by -3 or multiply by 1/3)

x = 1/3 (5y - 2)
