Step-by-step explanation:
Think of it this way what if an exponent had 1 so like 10^1
that still equals 10, and does not change anything, so you need to add one more to the exponent as the first number does not change how many types the number is multiplied. Hope this helps

Given m∠LMN=145 what is ∠XMN?
Answer:
(4x+5)°+(6x-10)°=145°
4x+6x+5-10=145°
10x-5=145°
10x=145+5
10x=150°
x=15
(6x-10)°=(6×15-10)°
=80°
The value of ∠XMN = 80.
What is angle?An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint.
The value of total ∠LMN = 145.
∠LMN = ∠LMX +∠XMN
145 = (4x + 5) + (6x - 10)
145 = 4x + 5 + 6x - 10
145 = 10x -5
10x = 150
x = 15
Substitute the value of x in ∠XMN = (6x - 10)
∠XMN = 6×15 - 10
= 90 - 10
∠XMN = 80
Therefore, the value of the angle ∠XMN = 80.

Solve F=D+Drt for t.....
Answer:
[tex]t = \frac{-D+F}{Dr}[/tex]
Step-by-step explanation:
Step 1: Flip the equation.
[tex]Drt + D = F[/tex]Step 2: Subtract D from both sides.
[tex]Drt + D - D = F - D[/tex] [tex]Drt = -D + F[/tex]Step 3: Divide both sides by Dr.
[tex]\frac{Drt}{Dr} = \frac{-D+F}{Dr}[/tex] [tex]t = \frac{-D+F}{Dr}[/tex]what divided by 25 = 4.8?
Answer:
120/25 = 4.8
Step-by-step explanation:
To set up the equation you would do this-
[tex]\frac{4.8}{1} =\frac{x}{25} \\[/tex]
Then cross multiply (multiply 4.8 by 25 and x by 1)
[tex]4.8(25) = x(1)\\120 = x[/tex]
A piano has a length of 8 feet and a width of x+2 feet, write an expression in simplest form of the perimeter of the piano.
Answer: 2(x + 10)
Step-by-step explanation: you have to add all of the perimeter sides together so you will have to times the length by 2 so your equation would be (8 × 2 = 16). Then the width by 2 ( 2 × (x+2) = 2x + 4) now you add them together
16 + 2x + 4
2x + 20
Now you have to take out the highest common factor which is 2
So it will be 2(x + 10)

Answer:
6.5 rounded from 6.53...
to see if this is correct we can:
13.5+9.5+6.5*3 = 42.5
but since we rounded it we can say its 6.5
Answer:
6.55 meters each day
Step-by-step explanation:
You know that in the end the fence must be 42.6 meters long.
On Monday & Tuesday, he installed 22.95 meters of fence. (We know this because 13.45 + 9.5 = 22.95).
So, how much is left? You find that by subtracting 22.95 from 42.6.
42.6-22.95 = 19.65 meters
There are 3 days left of fencing, and these days he will install equal lengths, so you can divide 19.65 meters by 3 days.
19.65 / 3 = 6.55 meters of fence per day
The Lucas numbers are defined by the recursive formula t1 = 2, t2 = 1, tn = tn - 1 + tn - 2, where n âN and n > 2. What are the first 9 Lucas numbers?
The first two are given to you, [tex]t_1=2[/tex] and [tex]t_2=1[/tex]. Use the recursive formula to get the 3rd term; then use the 2nd and 3rd terms to get the 4th; and so on.
Since the n-th Lucas number is the sum of the previous two Lucas numbers, you have
[tex]t_3 = t_2 + t_1 = 1 + 2 = 3[/tex]
[tex]t_4 = t_3 + t_2 = 1 + 3 = 4[/tex]
[tex]t_5 = t_4 + t_3 = 4 + 3 = 7[/tex]
[tex]t_6 = t_5 + t_4 = 7 + 4 = 11[/tex]
[tex]t_7 = t_6 + t_5 = 11 + 7 = 18[/tex]
[tex]t_8 = t_7 + t_6 = 18 + 11 = 29[/tex]
[tex]t_9 = t_8 + t_7 = 29 + 18 = 47[/tex]

At a farm the ratio of cows to horses was 9: 2 if there were 72 cows at the farm how many horses were there
Answer:
16 Horses!
Step-by-step explanation:
Since
9 : 2 = 72 : X
Then we know
2/9 = X/72
Multiplying both sides by 72 cancels on the right
72 × (2/9) = (X/72) × 72
72 × (2/9) = X
Then solving for X
X = 72 × (2/9)
X = 16
Therefore
9 : 2 = 72 : 16
What is the midpoint of the line segment?
Drag the coordinates to the boxes to correctly match the endpoints and midpoint
Using the midpoint concept, it is found that:
The midpoint of the line segment of endpoints [tex](2, \sqrt{3})[/tex] and [tex](-6, 5\sqrt{3})[/tex] is [tex](-2, 3\sqrt{3})[/tex].The midpoint of the line segment of endpoints [tex]\left(-\frac{5}{3}, \frac{2}{5}\right)[/tex] and [tex]\left(\frac{1}{3}, \frac{3}{2}\right)[/tex] is: [tex]\left(-\frac{2}{3}, \frac{19}{20}\right)[/tex]The midpoint of a line segment is given by the mean of the coordinates of it's endpoints.
For the first segment, which endpoints [tex](2, \sqrt{3})[/tex] and [tex](-6, 5\sqrt{3})[/tex]:
[tex]x_M = \frac{2 - 6}{2} = -2[/tex]
[tex]y_M = \frac{\sqrt{3} + 5\sqrt{3}}{2} = 3\sqrt{2}[/tex]
The midpoint is [tex](-2, 3\sqrt{2})[/tex]
For the second segment, which endpoints [tex]\left(-\frac{5}{3}, \frac{2}{5}\right)[/tex] and [tex]\left(\frac{1}{3}, \frac{3}{2}\right)[/tex]:
[tex]x_M = \frac{-\frac{5}{3} + \frac{1}{3}}{2} = -\frac{4}{6} = -\frac{2}{3}[/tex]
[tex]y_M = \frac{\frac{2}{5} + \frac{3}{2}}{2} = \frac{\frac{4 + 15}{10}}{2} = \frac{19}{20}[/tex]
The midpoint is [tex]\left(-\frac{2}{3}, \frac{19}{20}\right)[/tex]

Step-by-step explanation:
The 3 angles in a triangle sum to 180°
Sum the 3 given angles and equate to 180
2x + 3 + 7x - 5 + 3x + 14 = 180 , collect like terms
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14
Then
∠ F = 7x - 5 = 7(14) - 5 = 98 - 5 = 93° → D

A rectangle has a perimeter of 36 cm. Its width is 4 cm less than its length. Find
the length and width of the rectangle.
Answer:
14
Step-by-step explanation:
Perimeter = 2 x length + 2 x width = 2L + 2w
Width is 4 cm less than the length, so w = L-4
36 = 2L + 2(L-4)
36 = 2L + 2L - 8
36 = 4L - 8
44 = 4L
L = 11
w = 7
2(11) + 2(7) = 22 + 14 = 36
Length is 11, width is 7
