Answer:
135
Step-by-step explanation:
Ratio = 3 : 9
Angles are : 3x , 9x
3x + 9x = 180 {supplementary angles}
12x = 180 {divide both side by 12}
x = 180/12
x = 15
Larger angle = 9x = 9*15 = 135

Answer:
[tex]x^{2}[/tex] - [tex]z^{2}[/tex] - 2z[tex]\sqrt{5}[/tex] - 5
Step-by-step explanation:
This is the equation that you started off with:
(x - z - [tex]\sqrt{5}[/tex])(x + z + [tex]\sqrt{5}[/tex])
You can't really use FOIL on this because that's used in multiplying binomials, and this is a trinomial, but you can still break it up and simplify it this way:
(a + b + c)*(d + e + f) = (a(d + e +f)) + (b(d + e + f)) + (c(d + e + f))
So, applying that idea to the actual equation:
x(x + z + [tex]\sqrt{5}[/tex]) -z(x + z + [tex]\sqrt{5}[/tex]) - [tex]\sqrt{5}[/tex](x + z + [tex]\sqrt{5}[/tex])
= x^2 + xz + x[tex]\sqrt{5}[/tex] -xz -z^2 - z[tex]\sqrt{5}[/tex] - x[tex]\sqrt{5}[/tex] - z[tex]\sqrt{5}[/tex] - 5
= x^2 - z^2 - 2z[tex]\sqrt{5}[/tex] - 5
or [tex]x^{2} - z^{2} - 2z\sqrt{5} - 5[/tex]

Step-by-step explanation:
. Jacob and Sadie each got ahead on their skills practices. Jacob completed twelve fewer problems than twice the number Sadie completed. They completed a total of 127 problems. Which system of equations models this situation if Jacob completed j problems & Sadie completed s problems? A) j + s = 127
Answer:
2s-12=j
S+J=127
Step-by-step explanation:
ok so firstly you are going to have 2 problems. Jacob has 12 fewer than 2x Sadie's so it will look like this, 2s-12=j
. 2x Sadie's minus 12 will give you Jacobs. and then it tells you that together they have 127 completed so S+J=127

Can someone help me with this please?
Answer:
the function is linear
Step-by-step explanation:
now you figure this out in many ways,
but the easiest is to plot the points on a Cartesian x-y plane, rule a line through the points,if it's in a straight line then its linear if it's a curve its cubic
from the question, after plotting your points.ie (-9,-2),(-5,-7),(-1,-12),(3-17)
we get a straight line pointing downwards.

, it has no effect on the number of red socks so thewhen he draws out a sock the event is not affected by the draw a blue sock or the bla ck sock or the brown sock
A new car is purchased for 23900 dollars. The value of the car depreciates at 9.25% per year. To the nearest tenth of a year, how long will it be until the value of the car is 6000 dollars?
9514 1404 393
Answer:
14.2 years
Step-by-step explanation:
The value is described by the exponential function ...
y = (initial value)·(decay factor)^x
where y is the value after x years.
The decay factor is (1 - annual depreciation) = 1 - 0.0925 = 0.9075, so we want to find x when ...
6000 = 23900·0.9075^x
6000/23900 = 0.9075^x . . . . . . . . . . . . . . divide by 23900
log(6000/23900) = x·log(0.9075) . . . . . . . take logarithms
x = log(6000/23900)/log(0.9075) ≈ 14.2396
It will be about 14.2 years until the value of the car is $6000.
Answer:
14.2
Step-by-step explanation:
determine the value of k if g(x)=4x-k is a tanget to f(x)=-x²+8x+20
Answer:
This seems to be incomplete because we do not know where g(x) must be tangent to f(x). So i will assume that we want g(x) to be a tangent to f(x) in the point x0.
We know that for a function f(x), f'(x) is the tangent function in at the point x.
Where f'(x) = df(x)/dx
So we can find a value of k that is equal (for some value of x) to the first derivative of f(x).
g(x) = 4*x - k
f(x) = -x^2 + 8*x + 20
f'(x) = -2*x + 8
Now we want to find a value of k such that:
4*x0 - k = -2*x0 + 8
4*x0 - k = -2*x0 + 8
4*x0 + 2*x0 - 8 = k
6*x0 - 8 = k
Then if we want g(x) to be a tangent to f(x) = -x²+8x+20 in the point x0, we must have k = 6*x0 - 8
Can you please help me solve for x for this triangle please!!
Answer:
See below, please!
Step-by-step explanation:
Since this triangle is a right triangle, the two acute angles are always going to be complementary (adding up to 90 degrees). So we can set up an equation: 2x+3x+5=90. Solve this and we get x=17.
Hope this helped!
Terrence finished a word search in the time it took Frank. Charlotte finished the word search in the time it took Terrence. Frank finished the word search in 32 minutes. How long did it take Charlotte to finish the word search?
Answer:
Charlotte finished the word search in 16 minutes
Step-by-step explanation:
Terrence finished a word search in 3/4 the time it took frank. charlotte finished the word search in2/3 the time it took terrence. Frank finished the word search in 32 min. how long did it take charlotte to finish the word search
Frank finished the word search in 32 min
Terrence finished a word search in 3/4 the time it took frank
Terrence = 3/4 of 32 min
= 3/4 × 32 minutes
= (3×32)/4
= 96/4
= 24 minutes
Terrence finished a word search in 24 minutes
Charlotte finished the word search in 2/3 the time it took Terrence
Charlotte = 2/3 of 24 minutes
= 2/3 × 24
= (2×24)/3
= 48/3
= 16 minutes
Charlotte finished the word search in 16 minutes

Under her cell phone plan, Morgan pays a flat cost of $55.50 per month and $4 per gigabyte. She wants to keep her bill at $71.90 per month. How many gigabytes of data can she use while staying within her budget?
Answer:
4.1
Step-by-step explanation:
You would first subtract 55.50 from 71.90 which leaves you with 16.4,
Then you would divide 16.4 by 4 to find how many gigabytes she could use which gives you 4.1
