find the value of X, please!

Answers

Answer:

x=42°

Step-by-step explanation:

We know that 2 of the legs are congruent, so the angles opposite them will be congruent.

The angles of a triangle add up to 180°

This can be represented by [tex]96+2x=180[/tex]

[tex]2x=84[/tex]

[tex]x=42[/tex]

Hope this helps :-)

Answer: 42 degrees

Step-by-step explanation: Since this is an isosceles triangle, your remaining two angles will be equal

There are 180 degrees in any triangle

Since you have already used 96 degrees, you must subtract to find what is remaining

180-96=84

Since your remaining two angles are equal, you can half 84 to find your answer

84/2=42

Both x and your one remaining angle should be 42

X=42

Kiran is playing a video game. He earns 3 stars for each easy level he completes and 5 stars for each difficult level he completes. He completes more than 20 levels total and earns 80 or more stars

Answers

Answer:

10 easy levels and 10 difficult levels

Step-by-step explanation:

Given data

let the number of easy levels be x

and the number of difficult levels be y

so

x+y= 20----------1

and

3x+5y= 80------2

from 1

x=20-y

put this in 2

3(20-y)+5y= 80

60-3y+5y=80

2y=80-60

2y=20

y= 20/2

y= 10

put y= 10 in 1

x+10=20

x=20-10

x= 10

Hence Kiran played 10 easy levels and 10 difficult levels

Janice NEEDS 3 GALLONS of lemonade for a party. She has 4 quarts, 6 pints and 4 cups of lemonade already made. How many CUPS of lemonade does Janice have? Be sure to re-state the question when giving your answer.

Answers

Answer:

32 cups

Step-by-step explanation:

To find the total number of cups, we have to convert the measures that are not in cups to cups and add

1 quart  = 4 cups

4 quarts = 4 x4 = 16 cups

1 pint = 2 cups

6 pints = 2 x 6 = 12 pints

total number of cups = 16 + 12 + 4 = 32 cups

Are the graphs of y = -2x + 4 and y = (1/4)x -2 parallel, perpendicular, or neither? *

Answers

Answer: Neither

Step-by-step explanation:

For this to be paralell it would need to have the same slope. (They don't  have the same.) For this to perpandicular it would have to reciporcal  ( Ex: -2 reciporcal would -1/2 or 1/4 reciprocal would have to be 4)

Answer:

neither

Step-by-step explanation:

For two lines to be parallel, their slopes must be equal.

For two lines to be perpendicular, their slopes must have a product of -1. (The only exception is a vertical line and a horizontal line which are perpendicular, but the product of their slopes is not -1.)

When the equation of a line is written in the slope-intercept form,

y = mx + b,

m is the slope.

y = -2x + 4 has a slope of -2.

y = (1/4)x -2 has a slope of 1/4.

Clearly, -2 and 1/4 are not equal, so the lines are not parallel.

Now we find the product of the slopes.

(-2) * (1/4) = -2/4 = -1/2

The product of the slopes does not equal -1, so the lines are not perpendicular.

Answer: neither

consider the equation x^2-7x-8=0 and describe it's roots​

Answers

Answer:

there are two different, real roots.  

Step-by-step explanation:

The coefficients of this quadratic are {1, -7, -8}.  Let's find the discriminant, b^2 - 4ac.  In this case a = 1, b = -7 and c = -8 and so the discriminant value is

(-7)^2 - 4(1)(-8), or 49 + 32, or 81.

Because the discriminant is positive, we know immediately that there are two different, real roots.  

We are not asked to find the roots, but let's do it anyway:

      -(-7) ± √81

x = ------------------ => x = 8 and x = -2 (which are real and different from

              2                                           one another).

Alicia wants to cover a footrest in the shape of a rectangular prism with cotton fabric. The footrest is 14 inches by 11 inches by 13 inches. She has 1 square yard of fabric. Can she completly cover the footrest

Answers

Answer:

Since the footrest measures 1.54 square yards, Alice will not be able to cover it completely.

Step-by-step explanation:

Since Alicia wants to cover a footrest in the shape of a rectangular prism with cotton fabric, and the footrest is 14 inches by 11 inches by 13 inches while she has 1 square yard of fabric, to determine if she can she completly cover the footrest the following calculation must be performed:

1 square yard = 1296 square inches

14 x 11 x 13 = X

154 x 13 = X

2.002 = X

2.002 / 1.296 = 1.54

Thus, since the footrest measures 1.54 square yards, Alice will not be able to cover it completely.
