Answer:
Step-by-step explanation:
x+5+x+7x-5=180 degree (being the interior angles of a triangle)
9x=180
x=180/9
x=20 degree
Answer:
x° = 20°
Step-by-step explanation:
Sum of angles of triangles = 180°
Therefore,
(x + 5) + (7x - 5) + x = 180
x + 5 + 7x - 5 + x = 180
9x = 180
x = 20
∠M = (x + 5) = 20 + 5 = 25°
∠L = (7x - 5) = 140 - 5 = 135°
∠N = x = 20°

What is the factored form of 25x2 – 20x + 4?
A. (5x – 2)2
B. (5x + 2)2
O C. (5x + 1)(5x – 4)
D. (5x + 2)(5.x - 2)
Answer:
Step-by-step explanation:
This factors using a perfect square trinomial. You can recognize this by several characteristics. First off, the leading coefficient is a perfect square (25); second, the constant is also a perfect square (4). Third, the second sign is a + which means that both the signs inside the parenthesis are the same and they are both whatever the first sign is, - . Factoring this then, is the (square root of the leading coefficient times x - square root of the constant):
(5x - 2)(5x - 2) which simplifies down to
[tex](5x-2)^2[/tex], choice A.

100
2 StartRoot 10 EndRoot
Answer:
2,000,000
Step-by-step explanation:
First of all, I think that you are asking:
[tex]\sqrt{10}*\sqrt{10}*10*10\sqrt{10}*100*2\sqrt{10}[/tex]=?
So, because multiplication is commutative, we are allowed to group together what we know and what we will deal with later:
[tex]\sqrt{10}*\sqrt{10}*10*10\sqrt{10}*100*2\sqrt{10}[/tex] can be rewritten as
[tex](10*10*100*2)*\sqrt{10}* \sqrt{10}*\sqrt{10}*\sqrt{10}[/tex]
10*10*100*2=20,000
[tex]20,000(\sqrt{10}*\sqrt{10}*\sqrt{10}*\sqrt{10})[/tex]
So, what we do know is that when we take the square root of a number and multiply it by itself (or "square" it) we will get back the number that we started with.
So:
[tex]\sqrt{10}*\sqrt{10} =10[/tex]
We can rewrite what we had up top as:
[tex]20,000((\sqrt{10})*(\sqrt{10}))*((\sqrt{10})*(\sqrt{10}))[/tex]
[tex]20,000(10)(10)[/tex]
[tex]20,000(100)[/tex]
[tex]20,000(100)=2,000,000[/tex]

The width of a rectangle measures (3s+t) centimeters,and it’s length measures (3s-9t) centimeters. Which expression represents the perimeter,in centimeters of the rectangle ?
Answer:
12s - 16t
Step-by-step explanation:
2(3s + t) + 2(3s - 9t)
6s + 2t + 6s - 18t
12s + 2t - 18t
12s - 16t
Answer:Perimeter of the rectangle =(12s -16t)centimeters.
Step-by-step explanation:
The perimeter of a rectangle is given as 2(l+w)
Given that width of the rectangle=(3s+t)centimeters. and
Length of the rectangle=(3s-9t)centimeters.
Solving we have
Perimeter= 2(l+w)
Perimeter=2(3s+t +3s-9t)
Perimeter=2(3s+3s -9t+t)
Perimeter=2(6s-8t)
Perimeter=(12s -16t)centimeters.

The opposite of a function is its inverse
The ordered pairs that represent the inverse of function f(x) are (-2,4), (-2,-2), (-2,-1)
From the function, we have the following ordered pairs
(x,y) = (4,-2), (-2,-2), (-1,-2)
The inverse of a function (x,y) is (y,x).
So, we have:
(y,x) = (-2,4), (-2,-2), (-2,-1)
Hence, the ordered pairs that represent the inverse of function f(x) are (-2,4), (-2,-2), (-2,-1)

9. How much greater is 0.05723 than 0.005? ?
Answer:
0.05223
Step-by-step explanation:
0.05723 is 0.05223 greater than 0.005.
What is decimal?
A decimal number is one in which the whole number component and the fractional component are separated by a decimal point. The decimal point is the dot seen in decimal numbers. The decimal point is followed by digits that represent a number less than one.
As an illustration, consider the decimal value 17.48, where 17 is the entire integer and 48 is the decimal portion.
When is some number greater?When one number exceeds another, the phrase "more than" is used. Even greater than is utilised to compare the two weights.
How to solve it?
Take the difference
0.05723-0.005=0.05223
Hence, 0.05723 is 0.05223 greater than 0.005.

Determine and state an equation of the line perpendicular to the line 8x + 6y = 15 and passing through the point (3,-4)
Answer:
4y - 3x = -25
Step-by-step explanation:
The equation of a line in point-slope form is expressed as
y - y0 = m(x - x0)
(x0, y0) is the point
m is the slope
Given
(x0, y0) = (3, -4)
Also given the equation;
8x + 6y = 15
Rewrite in standard form;
6y = -8x+15
y = -8/6 x + 15/6
y = -4/3 x + 5/2
Slope m = -4/3
Since the required line is perpendicular to the given line =,
Slope = -1/(-4/3) = 3/4
Substitute into the formula;
y - (-4) = 3/4(x-3)
y + 4 = 3/4(x-3)
4(y+4) = 3(x-3)
4y + 16 = 3x - 9
4y - 3x = -9-16
4y - 3x = -25
This gives the required equation
Can somebody plz help answer these questions (only if u know how to do this) btw! P= probability anyway thanks :3
WILL MARK BRAINLIEST FOR WHOEVER CAN ANSWER THESE :DDD
Answer:
P(black): 4/9
P(yellow): 2/9
P(orange): 3/9
Step-by-step explanation:
There are 4 black cubes, 2 yellow cubes, and 3 orange cubes. Add all of the cubes together to know how many cubes there are total.
4+2+3 = 9
Now that you know there are 9 cubes, you see how many black cubes you can draw out of 9. You can draw 4 black cubes out of the 9 total cubes, so the probability is 4/9.
You see how many yellow cubes you can draw out of 9. You can draw 2 yellow cubes out of the 9 total cubes, so the probability is 2/9.
You see how many orange cubes you can draw out of 9. You can draw 3 orange cubes out of the 9 total cubes, so the probability is 3/9.
Answer:
5) 4/9
6) 2/9

Answer:
y = x²+8x+7
Step-by-step explanation:
according to the table, we get the point :
(-4, -9) as the vertex and (0, 7) as y-intercept
y = ax²+bx+c
=> the symetry axis :
x = -b/2a = -4
b=-4×2a = 8a
let a=1, => b = 8(1) = 8
y-intercept = (0, c) =(0, 7) => c =7
so, the equation might be :
y = x²+8x+7
An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded. Which could be the number of scoops sold if they rounded to the nearest thousand? Choose all answers that apply
Answer:
11,501 ≤ x ≤ 12,500
Step-by-step explanation:
When rounding, if the number is 1 more than half it gets rounded up and if it is exactly at half or less it gets rounded down. For example, since in this case we are rounding to the nearest 1000 anything above 501 gets rounded up and anything less than that gets rounded down. Therefore, since the shop sells 12,000 scoops per month the possible values for it to get rounded to the nearest thousand would be the following, were this is represented by the variable x.
11,501 ≤ x ≤ 12,500
