Answer 1

Answer:

$252

Step-by-step explanation:

The price of the computer is $400

On saturday it is on sale for 30% off

30% of 400 or .3 x 400 = 120

400 - 120 = 280

Then, if she gets there before 9am there is an addition 10% off of the sale price (280)

So, 10% of 280 or .1 x 280 = 28

280 - 28 = 252

Hope this helps!

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.


Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.


Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Answers

To find the line parallel to y = -2x - 5 that includes the point (-1, 3), we'll use the same slope (m = -2) since parallel lines have the same slope.

Using the point-slope form: y - y₁ = m(x - x₁)

Plug in the values: y - 3 = -2(x - (-1))

Simplify: y - 3 = -2(x + 1)

Now, we can find the y value of the point:

y - 3 = -2(-1 + 1)
y - 3 = 0
y = 3

So, the y value of the point is 3.

Find the number that is four greater than three times its additive inverse.

Answers

Answer:

1

Step-by-step explanation:

let the number=x

x-4=-3x

x+3x=4

4x=4

x=4/4=1

The number that is four greater than three times its additive inverse

is - 3n + 4.

What are additive and multiplicative inverses?

A number's additive inverse is a number that is added to it until the result is zero.

A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.

Let the unknown number be 'n' so its additive inverse is '-n'.

So,  the number that is four greater than three times its additive inverse is,

Three times of additive inverse is -3n.

Now the number is 4 greater than 3 times its additive inverse which is

= - 3n + 4.

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

Which image below is an acute triangle?

Triangle A has angles measuring ninety five degrees, forty five degrees, and thirty degrees. Triangle B has angles measuring one hundred degrees, twenty five degrees, and twenty five degrees. Triangle C has angles measuring fifty degrees, sixty five degrees, and sixty five degrees. Triangle D has angles measuring thirty degrees, one hundred ten degrees, and twenty degrees.

A. Triangle A
B.Triangle B
C. Triangle C
D. Triangle D

Answers

Answer:

Triangle C.

Step-by-step explanation:

Acute triangles are triangles that have acute angles. Acute angles are angles that are less than 90 degrees.

Triangles A, B and D all have at least one angle that is greater than 90 degrees. Triangle C is the only triangle that has all acute angles, therefore it is an acute triangle.

Triangle C is an acute angle triangle.

The correct option is (C).

What is a Triangle?

A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic.

As per the given data:

The values for all the angles in Triangle A, Triangle B and Triangle C is given.

To find out the acute angle triangle, if all angles is a triangle are lesser than 90°, then it's an acute angle triangle.

Triangle A:

95° > 90° {not acute}

45° < 90°

30° < 90°

This is not an acute angle triangle.

Triangle B:

100° > 90° {not acute}

25° < 90°

25° < 90°

This is not an acute angle triangle.

Triangle C:

50° < 90°

65° < 90°

65° < 90°

This is an acute angle triangle.

Triangle D:

30° < 90°

110° > 90° {not acute}

20° < 90°

This is not an acute angle triangle.

Hence, Triangle C is an acute angle triangle.
