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
Assuming you have accidentally type a "6" instead of a "b" in answers b and c, the answer is:

Answer:
4w² + 6w + 4Step-by-step explanation:
The missing dimension is:
The total height - 2× (height of the frame)6w² + 8 - 2(w² - 3w + 2) = 6w² + 8 - 2w² + 6w - 4 = 4w² + 6w + 4Explaination:
The missing dimension is: The total height - 2 times (height of the frame)
6w² + 8 - 2(w² - 3w + 2)
6w² + 8 - 2w² + 6w - 4
Answer:

Write a linear equation in slope-intercept form: 5y – 3x + 20 = 0
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 equation5y - 3x + 20 = 0
5y + 20 = 3x
move 20 to the right side5y = 3x - 20
Divide both sides of the equation by 5y = 3/5x - 4
This is our answer!

What is the volume (in cm^3) of a sphere with a circumference of 8.20 cm?
Answer:
9.31 cm³ (3 sf)
Step-by-step explanation:
Circumference of a sphere = circumference of a circle = 2[tex]\pi [/tex]r
⇒ 2[tex]\pi [/tex]r = 8.20 cm
⇒ r = 8.20 ÷ 2[tex]\pi [/tex] = [tex]\frac{41}{10\pi } [/tex]
Volume of sphere = [tex]\frac{4}{3} \pi r^3[/tex]
= [tex]\frac{4}{3} \pi (\frac{41}{10\pi }) ^3[/tex]
= [tex]\frac{68921}{750\pi ^2} [/tex]
= 9.310876397... = 9.31 cm³ (3 sf)

NO LINKS!!! Part 15, What is the area of this figure?
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.

Answer:
s = 25
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is
half the length of the third sise , that is
TW = [tex]\frac{1}{2} [/tex] UV , substitute values
s = [tex]\frac{1}{2} [/tex] (s + 25) ← multiply both sides by 2 to clear the fraction
2s = s + 25 ( subtract s from both sides )
s = 25

Answer:
∠CBD = 55°
Step-by-step explanation:
With respect to ΔBCD, angle BDA is an exterior angle. As such, its value is the sum of remote interior angles CBD and BCD:
80° = ∠CBD +25°
∠CBD = 55° . . . . . . subtract 25° from both sides
Can you give me an example of how to do logarithm?
Answer:
(look bellow)
Step-by-step explanation:
For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100:
log 100 = 2. because.
102 = 100. This is an example of a base-ten logarithm. ...
log2 8 = 3. because.
23 = 8. In general, you write log followed by the base number as a subscript. ...
log. ...
log a = r. ...

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.
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.

X/h+1 = -2
The value of xin terms of his
The value of x when h = 4 is
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

If 32 horses consume 112 kg of grass in a certain period, how much grass will be
consumed by 11 horses during the same period?
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
x = 38.5

Can you Factorise 22 + 10x
=> 22+10x
=> 2(5x+11)
This is the answer for your question
Answer:
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.
22/2=11
10/2=5
So the factorized expression is 2(11+5x)

NO LINKS!!! Please help me with this trig problem. Use the diagram. Part 2
4. b= 4
c= 6
Find a, A, and B
The decimal values are approximate.
==================================================
Given info:
b = 4c = 6This 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.
