The hole for a bird feeder post is 3 feet deep, the top of the post needs to be at least 5 feet above the ground. Identify an inequality that represents the required length of the post.
If hole for a bird feeder post is 3 feet deep, the top of the post needs to be at least 5 feet above the ground. Then x-3≥5 is the inequality that represents the required length of the post.
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
Given,
The hole for a bird feeder post is 3 feet deep,
the top of the post needs to be at least 5 feet above the ground
We need to find the inequality that represents the required length of the post.
Let x be the length of the post.
As, it is deeper then it has negative three.
There is given atleast, so it should be greater than or equal to.
x-3≥5
Hence, x-3≥5 is the inequality that represents the required length of the post.

Answer:
1. y=kx
2. y=60
Step-by-step explanation:
y is directly proportional to x
y=kx
Find Constant K, when y=30 & x=6
Make K the subject of the formula first
K=y/x
K=30/6
k=5
When k is 5, x is 12, find y
y=kx
y=5×12
y=60
Given directed line segment with endpoints A(-3, 1) and B(5, 13), what is the coordinate that partitions the line segment into a ratio of 1:3?
A(4, –1)
B(–1, 4)
C(–⅓, 5)
D(5, –⅓)
Answer:
B(–1, 4)
Step-by-step explanation:
We want to find a point P(x,y).
Since it is on the directed line segment AB in the ratio 1:3, it means that:
[tex]P - A = \frac{1}{1+3}(B-A)[/tex]
So
[tex]P - A = \frac{1}{4}(B-A)[/tex]
We apply this to both the x-coordinate and y-coordinate of P.
x-coordinate:
x-coordinate of A: -3
x-coordinate of B: 5
x-coordinate of P: x
So
[tex]P - A = \frac{1}{4}(B-A)[/tex]
[tex]x - (-3) = \frac{1}{4}(5 - (-3))[/tex]
[tex]x + 3 = \frac{1}{4} \times 8[/tex]
[tex]x + 3 = 2[/tex]
[tex]x = -1[/tex]
y-coordinate:
y-coordinate of A: 1
y-coordinate of B: 13
y-coordinate of P: y
So
[tex]P - A = \frac{1}{4}(B-A)[/tex]
[tex]y - 1 = \frac{1}{4}(13 - 1)[/tex]
[tex]y - 1 = \frac{1}{4} \times 12[/tex]
[tex]y - 1 = 3[/tex]
[tex]y = 4[/tex]
So the correct answer is given by option B.

Tim wrote the following statement:
"You can only draw one unique isosceles triangle that contains an angle of 70°."
Which statement is true? (1 point)
a
Tim is incorrect, because more than one triangle can be drawn with the given information.
b
Tim is correct, because only one unique triangle can be drawn with the given information.
c
Tim is incorrect, because the triangle described cannot be drawn with the given information.
d
None of the above.
Answer:
Step-by-step explanation:
I think its A IF NOT ITS B
Answer:
My answer would be: Tim is incorrect, because more than one triangle can be drawn with the given information.
Given:
Isosceles triangle and has a 70° angle.
An isosceles triangle is a triangle that has 2 congruent angle. Since all interior angle must have a sum of 180°, the possible angles of an isosceles triangle with a 70° angle are:
1) 180° - 70° = 110°
110° / 2 = 55°
Angles are 70°-55°-55°
2) 180° - 70° = 110°
110° - 70° = 40°
Angles are 70°-70°-40°
The given information can create 2 isosceles triangle. Thus, Tim is wrong in his claims.

Chase was trying to solve for x and y. He knows that the value of x is 3 times the value of y and that half of x plus twice y is equivalent to -14
Answer:
the value of x is -12 and the value of y is -4
Step-by-step explanation:
Given;
x = 3y ----- (1)
[tex]\frac{x}{2} + 2y = -14[/tex] ----(2)
Substitute the value of x into equation (2)
[tex]\frac{3y}{2} + 2y = -14\\\\multiply \ through \ by \ 2\\\\3y + 4y = -28\\\\7y = -28\\\\divide \ through \ by \ 7 \\\\y = -4\\\\solve \ for \ x\\\\x = 3y\\\\x = 3(-4)\\\\x = -12[/tex]
Thus, the value of x is -12 and the value of y is -4

Abe, Bob, Carl, Dan and Earl are going to stand in line for a photo. What is the probability that the boys will stand in alphabetical order from left to right in the picture
Answer:
0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture
Step-by-step explanation:
Probability:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
Arrangments of x elements:
The total number of arrangments of x elements is given by:
[tex]A_{x} = x![/tex]
Desired outcomes:
Standing in alphabetical order, so only 1 possible outcome, which means that [tex]D = 1[/tex]
Total outcomes:
Arrangments of 5 people, so
[tex]T = A_{5} = 5! = 120[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{120} = 0.0083[/tex]
0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture
