d. 01.5a + 3b - 4.4
e. 01.5a - 5.6b - 3.4

Answers

Answer 1

Answer:

B and D

Step-by-step explanation:

   6.2a - 5(1.5 - 0.6b) - 4.7a + 3.1

=  6.2a - 7.5 + 3b - 4.7a + 3.1

=  1.5a + 3b - 4.4

Yes

Step-by-step explanation:

Find the GCF of 22 and 10.

22 - 1, 2, 11, 22.

10 - 1, 2, 5, 10.

The GCF is 2.

Answers

Answer:

38.5 kg of grass

Step-by-step explanation:

We can solve this problem by using a proportion. (Kg of grass over horses)

Let x = the amount of grass 11 horses will eat in the same period of time.

112/32 = x/11      Cross multiply

1232 = 32x        Divide both sides by 32

The first term becomes:

[tex]x^a/(x^a+x^b+x^c)[/tex]

The graph shows the lengths and the perimeters for rectangles with a fixed area and whole-number dimensions.

a. What is the perimeter of a rectangle with a length of 2 meters?

Length=____________
Width=_____________

b. Describe the dimensions and shape of the rectangle that has the greatest perimeter represented in the graph?

c. Describe the dimensions and shape of the rectangle that has the least perimeter represented in the graph.

d. What is the fixed area? Explain your choice. ​

Answers

Answer:

  a. (P, L, W) = (32, 2, 14) . . . meters

  b. (P, L, W) = (58, 1, 28) . . . meters

  c. (P, L, W) = (22, 4, 7) . . . meters

  d. 28 m²

Step-by-step explanation:

a.

The perimeter of the rectangle is found on the vertical scale at the horizontal line through the point on the vertical line for length = 2 m. The width of the rectangle is found at the other point on that horizontal line.

  Perimeter: 32 m

  length: 2 m

  width: 14 m

__

b.

The greatest perimeter represented on the graph is the top line on which points are plotted. It is 58 meters. The two points on that perimeter line are lengths of 1 and 28 meters.

The rectangle with the largest perimeter shown on the graph has ...

  Perimeter: 58 meters

  length: 1 meter

  width: 28 meters

__

c.

The least perimeter represented on the graph is 22 m. The dimensions shown on that line are 4 m and 7 m.

  Perimeter: 22 m

  length: 4 m

  width: 7 m

__

d.

The fixed area is the product of length and width shown on any given perimeter line:

  1×28 = 2×14 = 4×7 = 28 . . . square meters

_____

Additional comments

This is all about reading and understanding a graph. As with many graphs, not every grid line is marked, and not every point is on a grid line. That means you need to use your skill at interpolation to determine the coordinates of any given point.

You also need to realize that the two "length" dimensions shown on any given perimeter line are the length and width of the rectangle. Either could be called "length" and the other could be called "width." We took our cue from the first question, which claimed a length of 2 meters. That is, we called the shorter dimension "length" to match the wording in that part of the problem statement.

Consider the equation below.

The value of xin terms of his
The value of x when h = 4 is

Answers

Answer:

x = 4

Step-by-step explanation:

we are given the equation

x/h + 1 = 2

we are also given a the value of h = 4

we are told to find x

let's use the equations and substitute in what we have first

x/h + 1 = 2  ➔  x/4 + 1 = 2

now we can solve for x

x/4 + 1 = 2

lets begin by subtracting one from both sides

now we are left with

x/4 = 1

now do the inverse of division which is multiplication

so we multiply both sides by the denominator 4

now we have

x = 4

Answer: 479 square feet

Step-by-step explanation:

17 x 14 = 238

18 x 6 = 108

19 x 7 = 133

238 + 108 + 133 = 479 square feet

Answer:

479 square feet

Step-by-step explanation:

The largest area with direct lengths is the lightest sides is 17 and 14 ft.

17 x 14 = 238

We know the width is 18 ft, and since the little sliver shows and 8, 14 - 8 = 6, the missing length.

6 x 18 = 108

Finally, we can find the last area of the final rectangle. The lengths are 7 and 19.

7 x 19 = 133

Now the last step is to add all of the areas of the shapes.

238 + 108 + 133 = 479 ft

The area of the figure is 479 square feet.

Circumference of a sphere = circumference of a circle = 2[tex]\pi [/tex]r

Find a, A, and B​

Answers

Answers:a = 2*sqrt(5) = 4.4721A = 48.1897 degreesB = 41.8103 degrees

The decimal values are approximate.

==================================================

Given info:

b = 4c = 6

This is a right triangle, so we can use the pythagorean theorem to find the missing side 'a'.

a^2 + b^2 = c^2

a^2 + 4^2 = 6^2

a^2 + 16 = 36

a^2 = 36 - 16

a^2 = 20

a = sqrt(20)

a = sqrt(4*5)

a = sqrt(4)*sqrt(5)

a = 2*sqrt(5)

a = 4.4721 approximately

--------------------------------------------

To find the missing acute angles, we'll need a trig ratio.

There are many options to choose from. I'll use cosine to find angle A

cos(angle) = adjacent/hypotenuse

cos(A) = b/c

cos(A) = 4/6

cos(A) = 2/3

A = arccos(2/3) .... this is the same as [tex]\cos^{-1}[/tex]

A = 48.1897

For angle B, I'll use sine

sin(angle) = opposite/adjacent

sin(B) = b/c

sin(B) = 2/3

B = arcsin(2/3) .... same as [tex]\sin^{-1}[/tex]

B = 41.8103

Or you could use the fact that A+B = 90.

If you know A = 48.1897, then B = 90-A = 90-48.1897 = 41.8103

All of these decimal values are approximate.

Write a linear equation in slope-intercept form: 5y – 3x + 20 = 0 ​

Answers

Slope intercept form is y = mx+ b

So in order to turn 5y-3x + 20 = 0 into Slope intercept form, all we need to do is solve for y!

Let's do it!

add 3x to the right side of the equation

5y - 3x + 20 = 0

5y + 20 = 3x

move 20 to the right side

5y = 3x - 20

Divide both sides of the equation by 5

y = 3/5x - 4
