Rohan is checking in poodles for a dog show. A miniature poodle must be between 10 in. and 15 in. at the shoulder. The body length must be no more than 16 in. In addition, the poodle’s shoulder height must be no more than 1 in. longer than its body length.
The graph shows the feasible region, where x represents the poodle’s body length and y represents the shoulder height.
Which ordered pairs meet all the constraints for a successful poodle measurement and make sense in context of the situation?

Answers
A) (15, 11)
D) (12, 10.5)
Answer:
(15, 11) and (12, 10.5).
Step-by-step explanation:
Let x represents the poodle’s body length and y represents the shoulder height.
A miniature poodle must be between 10 in. and 15 in. at the shoulder.
[tex]10\leq y\leq 15[/tex]
The body length must be no more than 16 in.
[tex]0\leq x\leq 16[/tex]
The poodle’s shoulder height must be no more than 1 in. longer than its body length.
[tex]y\le1+x[/tex]
From the below figure it is clear that only two points (15, 11) and (12, 10.5) lie in the feasible region.
Therefore, ordered pairs (15, 11) and (12, 10.5) meet all the constraints for a successful poodle measurement and make sense in context of the situation.

The expression to show how much money he has left is $(33.5 - 10.45).
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given that, Tim earned $16 babysitting and $17.50 mowing a lawn.
What Tim has earned we'll add which is $(16 + 17.50) = $33.5.
He paid $8.50 for a movie and bought a small popcorn for $1.95.
His spendings we'll also add which is $(8.5 + 1.95) = $10.45.
Now, to write an expression for how much money he has left we'll subtract
his total spending from his total earnings which is,

Answers
lets use the equation (3.14)(2^2)=30. first we must do the 2 squared which gives us 4 resulting in (3.14)4=30 now we multiply pi with 4 resulting in 12.56=30 now we do the division... and my answer is 2.39 i am not sure if this is right though so take caution when using my response
The height of the rain barrel is required.
The height of the barrel is 2.39 feet.
r = Radius of barrel = 2 feet
V = Volume of barrel = 30 cubic feet
h = Height of barrel
Since, the barrel is cylindrical the volume of the barrel is
[tex]V=\pi r^2h\\\Rightarrow h=\dfrac{V}{\pi r^2}\\\Rightarrow h=\dfrac{30}{3.14\times 2^2}\\\Rightarrow h=2.3885\approx 2.39\ \text{feet}[/tex]
The height of the barrel is 2.39 feet.

james age is 3x and 2(x + 3x) is Pauls age so we have:-
x + 3x + 2*4x = 120
12x = 120

The ages of James, Paul and Dan is required.
James is 30 years old, Paul is 80 years old and Dan is 10 years old.
Let the ages of James be [tex]j[/tex], Paul be [tex]p[/tex] and Dan be [tex]j[/tex].
James is three times the age of Dan

Paul is two times the sum of the ages of James and Dan

The combined ages of the people is 120

Ezra works two summer jobs to save for a laptop that costs at least $1100. He charges $15/hr to mow lawns and $10/hr to walk dogs. Recall the inequality that represents this situation: 15x + 10y ≥ 1100
Explain how to graph the solution set.
Answers
15x + 10y = 1,100
x-intercept:
15x + 0 = 1,100
x = 1,100/15 = 73.33
y-intercept:
0 + 10y = 1,100
y = 1,100/10 = 110
Now, plot points (73.33,0) and (0,110). Since the equality symbol is ≥, which has an equal sign to it, connect the points using a solid line.
Next, let's find a point on the graph. Suppose it is the origin at (0,0). Use this points to the equation.
15x + 10y ≥ 1,100
15(0) + 10(0) ? 1,100
0 ? 1,100
0 < 1,100
It makes the symbol ≥ false. Therefore, it means that the other region bounded by the line is the solution. So, you shade this area. The final graph is shown in the picture attached.
To graph the solution set of the inequality 15x + 10y ≥ 1100, find the intercepts of the graph and draw a line passing through them. Then, test a point not on the line to determine which side represents the solution set. The solution set of the inequality is the region below the line on the graph.
Explanation:To graph the solution set of the inequality 15x + 10y ≥ 1100, we can start by identifying the intercepts of the graph. An intercept is a point where the graph intersects either the x-axis or the y-axis. To find the x-intercept, we set y = 0 in the inequality: 15x + 10(0) ≥ 1100. Simplifying this equation, we have 15x ≥ 1100. Dividing both sides by 15, we get x ≥ 73.33. Therefore, the x-intercept is (73.33, 0).
To find the y-intercept, we set x = 0 in the inequality: 15(0) + 10y ≥ 1100. Simplifying this equation, we have 10y ≥ 1100. Dividing both sides by 10, we get y ≥ 110. Therefore, the y-intercept is (0, 110).
After finding the intercepts, we can draw a line passing through these two points. Since the inequality is ≥, the line will be solid (including the points on the line). Finally, we determine which side of the line represents the solution set. We can choose a test point not on the line, such as (0, 0), and substitute its coordinates into the inequality. If the inequality is true, the shaded region representing the solution set should be below the line.
If the inequality is false, the shaded region should be above the line. In this case, substituting (0, 0) into the inequality gives 15(0) + 10(0) = 0, which is less than 1100. Therefore, the shaded region should be below the line. The solution set of the inequality 15x + 10y ≥ 1100 is the region below the line on the graph.

Since EF and HJ are parallel and EJ is a transversal, ∠JHG and ∠EFG are alternate interior angles and are congruent. Again we have that ∠EGF and ∠HGJ are vertical angles and are congruent; this gives us two angles and an included side, which is the ASA congruence theorem.

Answer:
Option D is correct.
The measure of [tex]\angleWYX = 150^{\circ}[/tex]
Step-by-step explanation:
[tex]\triangle WXY[/tex] is isosceles and [tex]\angle YWX[/tex] and [tex]\angle YXW[/tex] are base angles.
Isosceles Triangle:
A triangle with two equal sides, and two congruent base angles that means the angles are equal
By the definition, the base angles are equal i.e, [tex]m\angle YWX=m\angle YXW[/tex]
Since, YZ bisects [tex]m\angle WYX[/tex]
Angle Bisector theorem: An angle bisector is a line or ray that divides an angle into two equal angles
then, [tex]\angle WYX =2\angle XYZ[/tex] or
Substitute the value of [tex]\angle XYZ=(15x)^{\circ}[/tex] ;
[tex]\angle WYX =2(15x)^{\circ} = (30x)^{\circ}[/tex]
The sum of measures of these three angles of triangle WXY is equal to the 180 degree.
In triangle WXY we have;
[tex]\angle YXW+\angle WYX+\angle YWX=180^{\circ}[/tex]
Substitute the value of [tex]m\angle YWX=m\angle YXW=(2x+5)^{\circ}[/tex] and [tex]\angle WYX=(30x)^{\circ}[/tex] in above formula:
[tex]2\angle YXW+30x=180^{\circ}[/tex] or
[tex]2\cdot(2x+5)+30x=180^{\circ}[/tex]
Simplify:
[tex]4x+10+30x=180^{\circ}[/tex]
Combine like terms ;
[tex]34x+10^{\circ}=180^{\circ}[/tex] or
[tex]34x=170^{\circ}[/tex]
Simplify;
[tex]x= \frac{170}{34} =5^{\circ}[/tex]
Substitute the value of x in [tex]\angle WYX [/tex];
[tex]\angleWYX = (30x)^{\circ} = 30 \cdot 5 = 150^{\circ}[/tex]
Therefore, the measure of [tex]\angleWYX = 150^{\circ}[/tex]

A fair coin is flipped six times. what is the probability that heads occurs exactly 4 times if it is known that heads occurs at least four times?
Answers
A fair coin is flipped six times. Then 1/22 is the probability that heads occurs exactly 4 times if it is known that heads occurs at least four times
What is Probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
The probability that heads occurs exactly 6 times if it is known that heads occurs at least four times is
P{H=6|H≥4}
= P{(H=6)∩(H≥4)}/P{H≥4}
= P{H=6}/P{H≥4}
We need to calculate P{H=6}
P{H=6} = C(6,6)(½)6
= (½)6
P{H≥4} = P{H=4} + P{H=5} + P{H=6}
= C(6,4)(½)4(½)2 + C(6,5)(½)5(½) + C(6,6)(½)6
= (½)6[C(6,4) + C(6,5) + C(6,6)]
= (½)6[15 + 6 + 1]
= (½)6(22)
Therefore,
P{H=6|H≥4} = 1/22
1/22 is the probability that heads occurs exactly 4 times if it is known that heads occurs at least four times

Jim answered 30 out of 35 questions correctly, which is 85.7% correct when calculated using the percentage formula.
Explanation:Jim got 30 questions correct out of a total of 35. To find the percentage of questions he got correct, you can use the formula for calculating percentages: Percentage = (Number of correct answers ÷ Total number of questions) × 100%.
