Find the value of x pls I’ll give brainleist.
Answer:
x=15°
Step-by-step explanation:
We can see angle 6x-5 has a corresponding angle above it, which is congruent to it. That angle is supplementary with angle 7x-10. We can tell because it forms a straight angle with it. Supplementary angles add to 180°.
(7x-10)+(6x-5)=180
7x-10+6x-5=180
13x-15=180
13x=195
x=15

Let's assume a typical New Zealand farmer raising sheep owns 250 hectares and averages about 10 livestock units per hectare. If each ewe earns the farmer $20/year, how much money does that farmer earn in one year?
Answer:
$50,000
Step-by-step explanation:
We have an average of 10 livestock units per hectare
The number of units in 250 hectares will be;
250 * 10 = 2,500 units
Amount earned per unit is $20 per year
So, for 2,500 units, we have
2500 * $20 = $50,000

So supplementary angles are ones that add up to 180degrees and complementary ones add up to 90degrees.
So for the left side, you find what angle is supplementary to the given one. For the angle of 35, another angle of 145 will add up to 180.
The right side want you to find the complementary angles, so for the angle of 18, another angle of 72 will add up to 90.
I always forget supplementary vs complementary, but a little bit of practice will help a lot.

Which is the factored form of x(w – 1) + (W – 1)?
22 pts
Answer:
Solution given:
x(w – 1) + (W – 1)
distribute it:
xw-x+w-1
xw+w-x-1
take common from each term
w(x+1)-1(x+1)
take common again
(x+1)(w-1)
the factored form of x(w – 1) + (W – 1) is (x+1)(w-1).

Solve algebraicallu for the solutions of equations below.
Step-by-step explanation:
Okay, the first step is to rewrite this equation in "vertex form." You can search that up but it's basically just (h/k).
y = ( x − 1) 2 + 3
Now, we are going to use the vertex form, "y = a (x - h)2 + k, to get the values of a, h, and k.
By using the form we get 1 for the value a, 1 for the value h, and 3 for the value k.
1 = a
1 = h
3 = k
Becuse the value of a is positive, the parabola opens up! (A parabola is the U shaped line in a graph, so that opens up.)
Now, we find the vertex (h,k)
which is (1,3)
Now we find the p from the vertex to the focus. (vertext the top, focus one of the points.)
Follow this formula to find the distance from the vertex to a focus by using this formula
1/4a.
Now we just gonna substitue 1 for a, since we know that 1 equals a above ^
1/4 * 1
Solving that, we got a nice little 1/4.
Next we find the focus
"Find the focus.
The focus of a parabola can be found by adding p to the y-coordinate k if the parabola opens up or down.
(h,k+p)
Substitute the known values of h, p, and k into the formula and simplify.
(1,134)
Find the axis of symmetry by finding the line that passes through the vertex and the focus.
x=1
Find the directrix.
y=114
Use the properties of the parabola to analyze and graph the parabola.
Direction: Opens Up
Vertex: (1,3)
Focus: (1,134)
Axis of Symmetry: x=1
Directrix: y=114
Select a few x values, and plug them into the equation to find the corresponding y values. The x values should be selected around the vertex.
xy−1704132437
Graph the parabola using its properties and the selected points.
Direction: Opens Up
Vertex: (1,3)
Focus: (1,134)
Axis of Symmetry: x=1

it rained nine days in the month of april .based on this ,what is the probaility that is does not rain on the first day of may?
==========================================================
Explanation:
There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.
If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.
The empirical probability of it not raining on the first of May is therefore...
1 - (probability it rains)
1 - (3/10)
(10/10) - (3/10)
(10-3)/10
7/10
We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.

A kite is flying on a string that is 73 feet long. The angle
the kite makes with the ground is 51 degrees. How high
is the kite flying?
Answer:
56.73 ft
Step-by-step explanation:
Given:
51° (angle)
73ft (hypotenuse)
With the given information use sin to determine the height of the kite.
sin51° = x/73
solve for x (height)
x= 73*sin51°
x= 56.73ft

Step-by-step explanation:
Find f(-2) for f(x)= 5x3^x
Answer:
f(-2) = 90
Step-by-step explanation:
Plugging in the value of f(x) into the equation:
f(-2) = 5(-2)3^(-2)
f(-2) = 5(-2)(-9) - evaluate the power first
f(-2) = 90 - multiply from left to right to obtain answer
Can someone plz help me with this plz that will be lovely
Answer:
C) 25.13
Step-by-step explanation:
The formula for circumference is 2(pi)r.
In order to find r, or the radius, we can divide the diameter by 2.
d/2=r
8/2=4
r=4
Plug the radius into the formula
2(pi)4
And finally, plug it into your calculator.
2(pi)4 = ~25.13
