Yesterday, a shipping company delivered a combined total of 50,995 letters and packages. If
they delivered 4,459 packages, how many letters did they deliver?

Answer

the answer would be

D(5,-2).

Answer:

D(-6, 1)

Step-by-step explanation:

To determine the solution we can start by calculating the slope of AB;

A(-1, 4), B(2, -5)

m = -5 - 4 / 2 - (-1) = -9 / 3  = -3

Then CD, if to be perpendicular, should have the 'negative reciprocal' of the slope of AB. In other words it should have a slope of 1/3. We are given point C as (3, 4) so let's take each of the given options for point D, and find the slope using the two points. If the slope is 1/3rd then that  is the correct option.

Now I already know the answer, so instead of going through all the options I will just check the slope with the correct answer choice. You will find the slope to be 1/3rd;

C(3, 4), D(-6, 1)

m = 1 - 4/- 6 - 3  = -3/-9 = 1/3rd

Correct, as you can see

So your solution is option c

Answer:

$8.46

Step-by-step explanation:

This is assuming that the sales tax is applied on the pre discounted item.

m = -3

point = (-4,6)

You need to put this in point slope form.

y - 6 = - 3( x + 4 )

distribute

y - 6 = -3x - 12

add 6 to 12

y = -3x - 6

answer : y=-3x-6

Answer:

(2x^2 + x-7)/3x+ 3

Step-by-step explanation:

Here, we want to write the following as a single fraction;

2x-1/3 - 2/x + 1

That will be;

(2x-1)(x + 1) -2(3)/3(x+ 1)

= 2x^2+ 2x-x-1-6/3(x + 1)

= (2x^2+x-7)/3(x+1)

= (2x^2 + x-7)/3x+ 3

Answer:

Step-by-step explanation:

use Pythagorean theorem a² + b² = c²

where a = 8

           b = 15

           c = s (which is unknown)

plugin values into the formula:

a² + b² = c²

8² + 15² = s²

s = √(64 + 225)

s = √289

s = 17

Answer:

Area of triangle B is 112 cm²

Option A is correct option.

Step-by-step explanation:

The dimensions of triangle B are twice the dimensions of triangle A.

Area of triangle A = 28 cm²

We need to find area of triangle B

We know that if base = b and height = h for triangle A

The area of triangle A will be: [tex]Area_A=\frac{1}{2}\times b \times h[/tex]

The dimensions for triangle B will be:

[tex]h_B = 2 h_A\\b_B = 2 b_A[/tex]

Putting in formula we get:

[tex]Area_B=\frac{1}{2}\times b\times h \\Area_B=\frac{1}{2}\times (2b)\times 2(h)\\Area_B=4( \frac{1}{2}\times b\times h)\\Area_B=4(Area_A)[/tex]

SO, we get [tex]Area_B=4(Area_A)\\[/tex]

We have Area_A = 28 cm²

Area of triangle B Area _B is:

[tex]Area_B=4(28)\\Area_B=112\:cm^2[/tex]

So, Area of triangle B is 112 cm²

Option A is correct option.

Answer:

(4x+7)(4x-7)

Step-by-step explanation:

Answer: Sometimes

Step-by-step explanation:

This is a very tricky question. We know that in an isosceles triangle, two sides are the same. Because of this, we know that the right angle is always 90 degrees, and the other sides would be 45 degrees each because all triangles add up to 180 degrees. A right triangle could also be scalene, meaning none of the sides are the same, for example a scalene triangle could have sides of 44, 46, and 90 degrees. Rest assured, a right triangle will never be equalateral. Hope this helps :) Merry Christmas

Answer: $1,200

Step-by-step explanation:

Since multiplying 25% would take off 25% from 300, do the opposite (aka divide .25 from 300).

300/.25 = 1,200

Answer:

Ratio of flour to chocolate = 6 : 4

= 3 : 2

Step-by-step explanation:

Original recipe

Flour = 3 cups

Chocolate = 2 cups

Ratio of flour to chocolate = 3 : 2

To double the original recipe

Flour = 3 cups × 2

Chocolate = 2 cups × 2

Flour = 6 cups

Chocolate = 4 cups

Ratio of flour to chocolate = 6 : 4

= 3 : 2

Answer:

Yes, the number of knots is proportional to the number of rows.

Step-by-step explanation:

The number of knots is proportional to the number of rows, because whenever there is a new row then it implies that there is new knot.

Meaning, as the number of rows increases, the number or knots increases. This is a proportional relationship.

Answer:

-3/5

Step-by-step explanation:

Let's go from the point (5, 8) to the point (10, 5).  We can see immediately that x (the 'run') increases by 5 and y (the 'rise') decreases by 3.  Thus, the slope of the line connecting these two points is m = rise/run = -3/5.

Both of these lines have the slope -3/5, given that they are parallel lines.

Answer:

25%

Step-by-step explanation:

Since there are two coins, it's 50%, and since there are two sides to choose from, that would mean 25%. There's a 25% chance either will lie on heads, tails, or both heads or both tails.

Answer:

25%

Step-by-step explanation: because one coin landing on heads is 50%, but since there are two coins you cut 50% in half
