How many 3/4 pound packages can you make with 6.5 pounds of sunflower seeds?

Answers

Answer:

9 bags

Step-by-step explanation:

Weight each bag should be = 3/4 pound (0.75 pound)

Total weight of sunflower seeds available = 6.5 pounds

Number of packages made = 6.5/ 3/4

                                              = 8.66666666667

                                              = So 9 bags at the most

If you write 8, then  you wouldn't  be able to fit the other 0.5 pound and if you put 9, well you will have enough more space to put 6.5 pounds.

Hope this helps!!

Simplify 5c-6d+4c+3d

Answers

Answer:

9c - 3d

Step-by-step explanation:

5c-6d+4c+3d

Gather the like terms,

5c + 4c - 6d + 3d

9c - 3d

Hope it helps!<3

Simplifying

5c + -6d + 4c + 3d = 0

Reorder the terms:

5c + 4c + -6d + 3d = 0

Combine like terms: 5c + 4c = 9c

9c + -6d + 3d = 0

Combine like terms: -6d + 3d = -3d

9c + -3d = 0

Solving

9c + -3d = 0

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '3d' to each side of the equation.

9c + -3d + 3d = 0 + 3d

Combine like terms: -3d + 3d = 0

9c + 0 = 0 + 3d

9c = 0 + 3d

Remove the zero:

9c = 3d

Your answer: 9c=3d

Answer:

Divide both sides by −5.

Dividing by −5 undoes the multiplication by −5.

Divide 10+4y by −5.

x=− 5/4y

−2

The required intercepts of the given equation is x = -2 and y = -2.5.

What is the intercept?

Distance from the origin to points where a line crosses an axis is known as the x-intercept and the y-intercept, respectively.

Here,
Given the equation of the line,
-5x-4y=10

Now, in order to determine the intercepts of the equation put x = 0 and y = 0 individually,

So,
x = 0
-4y = 10
y = -2.5

Now, put y = 0
-5x = 10
x = -2

Thus, the required intercepts of the given equation is x = -2 and y = -2.5.

In an isosceles triangle, the measure of a base angle is (2x+5)° . At the vertex the measure of an exterior angle is (5x-3)°
There will be an extention at the vertex

Answers

Answer:51.14

Step-by-step explanation:since its an isosceles triangle all interior angles are gonna be equal the exterior angle plus interior angle is will be kept equal to 360

2x+5+5x-3=360

7x+2=360

7x=358

x=51.14

The measure of each angle is 31, 31 and vertex angle is 118.

What is Exterior angle Property?

If a triangle side is created, the outside angle that results is equal to the product of the two opposite internal angles.

Given:

Base angle = (2x+ 5) and Vertex = (5x- 3)

So, We know that the exterior angle is equal to sum of opposite interior angle

5x- 3 = 2x+ 5 + 2x + 5

5x - 3= 4x + 10

x= 13

Thus, Each angle measure 2(13)+ 5 = 31 and

third angle = 180 - (5x- 3) = 180- 62 = 118

Hence, the measure of each angle is 31, 31 and vertex angle is 118.

How to illustrate the information?

It should be noted that Sarah buys a package of 500 jewelry to decorate 4 different pairs of jeans and it was stated that she uses the same number of Jewelry each pair of jeans.

Therefore, it should be noted that the number of jewelry that she will use for each pair of jeans will be:

= Number of jewelry / Number of jeans

= 500 / 4.

= 125

we see that there is one gift that weighs 1/8 pounds which is the lightest package.

The weight of the lightest package is:

= 1/8 pounds

we see that there are 4 gifts that weigh 6/8 pounds for each gift which is the heaviest package.

The weight of the heaviest package is:

= 4 x 6/8

= 3 pounds

The difference between the weight of the heaviest package with the lightest package is:

= 3 - 1/8

= (24 - 1) / 8

= 23/8

= 2 (7 / 8) pounds

Thus the heaviest package is 2 (7/8) heavier than the lightest package.

A mountain climber records her altitude and the surrounding temperature at various points as she ascends a mountain. She then plots the points on a scatter plot and draws a line of best fit. The equation of the line is y=−3.6x+59 , where x is the altitude in thousands of feet and y is the temperature in degrees Fahrenheit (°F). What does the slope of the equation represent in this scenario?

Answers

Answer:

-3.6

Step-by-step explanation:

The general equation of a straight line formula is represented as y = mx + c, where m is the gradient or slope of the line and c is called the intercept on the y-axis.

The equation of the line in the question above is y= −3.6x + 59 ,

Therefore comparing both equations together,

y = mx + c = y = −3.6x + 59

m = -3.6

Therefore, the slope of the equation represent in this scenario is -3.6
