Help me quick!! A rancher has a field in the shape of the polygon shown.
9514 1404 393
Answer:
18 sheep
Step-by-step explanation:
The triangle cut from the upper right corner has a height of 200-100=100 m and a width of 200-120=80 m. Its area is given by the triangle area formula ...
A = 1/2bh
A = 1/2(80 m)(100 m) = 4000 m²
__
The area of the square that includes that triangle is ...
A = LW
A = (200 m)(200 m) = 40000 m²
So, the area of the field where the farmer can keep sheep is ...
field area = 40000 m² -4000 m² = 36000 m²
At 2000 m² per sheep, the field will support ...
(36000 m²)/(2000 m²/sheep) = 18 sheep

solve for all values of x in simplest form
Answer:
x = 1/12
1/12 = 0.833
Step-by-step explanation:
to find the value of x
4+ |2-3x| =7
8 - 12x = 7
-12x = 7-8
-12x = -1
x = 1/12
if we write 1/12 in simplest form so
1/12 = 0.833

My neighbor has two cats and both cats have yellow eyes.
Therefore when two cats live together, they will both have yellow eyes.
The given conclusion uses inductive reasoning because it is based on which of the following?
A two observations
B using previously-proven theorems to show that two cats living together will have yellow eyes.
C showing that all cats with yellow eyes live together
D many observations
A: two observations.
The rest would prove for definite but due to the lack of observations (one case, two observation) this allows us to disprove (most likely) this conclusion.
The radius of a monocycle wheel is 35 cm. How many revolutions will the wheel make in travelling 440m?
Answer:
200
Step-by-step explanation:
circumference of wheel =2πr = 219.91cm = 2.19m
total revolutions= total distance/circumference of wheel
= 440/2.19= 200.080

The volume of water in a vase is proportional to the depth
of the water. When there are 63 mL of water in the vase,
the depth is 7 cm. How much water is in the vase when
the depth is 9 cm?
A: 49 mL
B: 810 mL
C: 108 mL
D: 81 mL
Step-by-step explanation:
[tex]\frac{63}{7}=\frac{l}{9}[/tex]
[tex]l=81\text{ ml}[/tex]
Answer:
D
Step-by-step explanation:
We are given that the volume of water in a vase is proportional to the depth of the water. In other words, we can write that:
[tex]\displaystyle V = kd[/tex]
Where V is the volume, d is the depth of the water, and k is the constant of proportionality.
When there are 63 mL of water in the vase, the depth is 7 cm. Hence, V = 63 when d = 7:
[tex]\displaystyle (63) = k(7)[/tex]
Solve for k:
[tex]\displaystyle k = \frac{63}{7} = 9[/tex]
Hence, our equation is:
[tex]V = 9d[/tex]
Then when the depth of the vase is 9 cm:
[tex]\displaystyle V = 9(9) = 81\text{ mL}[/tex]
There will be 81 mL of water in the vase.
Hence, our answer is D.

The probability of rolling something less than 5 is 1/3.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, A 12-sided die can be made from a geometric solid called a dodecahedron.
The sample space is, {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.
So, The probability of getting any number is 1/12.
Therefore, The probability of getting a number less than 5 is,
P(1) + P(2) + P(3) + P(4).
= 1/12 + 1/12 + 1/12 + 1/12.
= 4/12.
= 1/3.
So, The probability of getting a number less than 5 is 1/3.

vertex of h(x)=−4x 2 +12x−7
Answer:
x = 1.5
Step-by-step explanation:
To get the vertex of a quadratic equation you can use the formula
x = -b/2a
where f(x) = ax² + bx + c
So you would get -12/2(-4)
-12/-8
x = 1.5
Then substitue x in the equation to find y. I won't be doing that here
What is the length of AC⎯⎯⎯⎯⎯?
The length of AC in the given triangle ABC as per the given condition is equal to 4 units.
To find the length of side AC (opposite angle BAC and BCA) in triangle ABC,
Use the triangle's angle-side-angle (ASA) property.
Side length of AB = x + 4,
Side length of BC = 3x - 8,
Side length of AC = x,
and m∠BAC = m∠BCA.
First, let's write down the ASA property:
If in two triangles, two angles and the included side of one triangle are equal to two angles and the included side of the other triangle,
Then the two triangles are congruent.
Here, angle BAC and angle BCA are equal, and their included side AC is common to both triangles.
So, set up the equation,
x + 4 = 3x - 8
Now, solve for x:
This implies,
⇒3x - x = 4 + 8
⇒ 2x = 12
Divide both the side by 2 we get,
⇒ 2x / 2 = 12/2
⇒ x = 6
Now that found the value of x, find the length of AC:
AC = x = 4
Therefore, the length of AC is 4 units.

Given n(J) = 285, n(K) = 197 and n(J ∪ K) = 431, find n(J ∩ K).
By the inclusion/exclusion principle,
n(J ∩ K) = n(J) + n(K) - n(J U K)
n(J ∩ K) = 285 + 197 - 431

The manager of a store that specializes in selling tea decides to experiment with a new blend. She will mix some Earl Grey tea that sells for $6 per pound with some Orange Pekoe tea that sells for $4 per pound to get 400 pounds of the new blend. The selling price of the new blend is to be $4.50 per pound, and there is to be no difference in revenue from selling the new blend versus selling the other types. How many pounds of the Earl Grey tea and Orange Pekoe tea are required?
The blend should have _ pounds of Earl Grey and _ pounds of Orange Pekoe.
9514 1404 393
Answer:
100 pounds Earl Grey300 pounds Orange PekoeStep-by-step explanation:
Let x represent the number of pounds of Earl Gray tea in the mix. Then the total cost of the mix is ...
6x +4(400-x)=4.50(400)
2x +1600 = 1800 . . . . . . . simplify
2x = 200 . . . . . . . . . . . subtract 1600
x = 100 . . . . . . . . . . . divide by 2. Pounds of Earl Grey
(400 -x) = 300 . . . . . Pounds of Orange Pekoe
The blend should have 100 pounds of Earl Grey and 300 pounds of Orange Pekoe.
_____
Additional comment
It is easy to show that the relationship between the quantities of high-cost (H) and low-cost (L) items in the mix (M) is ...
fraction of mix that is H is (M -L)/(H -L)
Here, we have H=6, L=4, M=4.5, so the fraction of the mix that is Earl Grey is ...
(4.5 -4)/(6 -4) = 0.5/2 = 0.25
There are 400 pounds of mix, so 0.25(400) = 100 pounds is Earl Grey.
The solution above is essentially 2-step, so using this relation doesn't necessarily save any steps. It just makes it possible to solve the problem in your head.
