The number 0.66 can be written as a terminating decimal as a quotient of integers is 33/50.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
The decimal number is 0.66 which is non-terminating.
As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We can write the number 0.66 as:
= 66/100
= On simplification:
= 33/50
Thus, the number 0.66 can be written as a terminating decimal as a quotient of integers is 33/50.

A camel can drink 15 gallons of water in 10 minutes. at this rate, how much water can the camel drink in 77 minutes?
To solve this problem, we simply have to use ratio and proportion.
We know that 15 gallons is consumed in 10 minutes therefore the conversion factor is:
15 gallons / 10 minutes
Therefore in 77 minutes:
water consumed = (15 gallons / 10 minutes) * 77 minutes
water consumed = 115.5 gallons

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.
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.

Jim got 30 questions correct out of a total of 35. what was the percentage he got correct?
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%. Applying this formula to Jim's case: Percentage = (30 ÷ 35) × 100% = 0.857 × 100% = 85.7%. Therefore, Jim got 85.7% of the questions correct.

We are given that EF is parallel to HJ. This makes EJ a transversal. This also means that ∠HJG and ∠GEF are alternate interior angles and are therefore congruent. We also know that ∠EGF and ∠HGJ are vertical angles and are congruent. This gives us two angles and a non-included side, which is the AAS congruence theorem.
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.

match each point with one of the following fractions 5/6, 7/12, 1/8, 5/16
A=5/6 B= 5/16 C= 7/12 D= 1/8
A= 1/8 B= 5/16 C= 7/12 D= 5/6
A= 7/12 B= 5/6 C = 5/16 D = 1/8
A= 5/16 B= 1/8 C = 7/12 D= 5/6
Answer:
The correct option is A= 1/8 B= 5/16 C= 7/12 D= 5/6
Step-by-step explanation:
Consider the provided fractions.
First convert each fraction into decimal form as shown:
5/6 = 0.833..
7/12 = 0.5833..
1/8 = 0.125
5/16 = 0.3125
The largest number among them is 0.833.. i.e 5/6 and the smallest number among them is 0.125 i.e 1/8
Arrange them in increasing order as shown:
0.125, 0.3125, 0.5833.., 0.833.. or 1/8, 5/16, 7/12, 5/6
Now consider the provided figure. The alphabets are showing the number are in increasing order
Thus, the correct option is A= 1/8 B= 5/16 C= 7/12 D= 5/6

PLEASE EXPLAIN THE STEPS
A. 5°B.15°C.75°D. 150°
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]

The combined age of three relatives is 120 years. James is three times the age of Dan, and Paul is two times the sum of the ages of James and Dan. How old is each person?
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
[tex]j=3d[/tex]
Paul is two times the sum of the ages of James and Dan
[tex]p=2(j+d)\\\Rightarrow p=2(3d+d)\\\Rightarrow p=2(4d)=8d[/tex]
The combined ages of the people is 120
[tex]j+p+d=3d+8d+d\\\Rightarrow 120=12d\\\Rightarrow d=\dfrac{120}{12}\\\Rightarrow d=10[/tex]
[tex]j=3d=3\times 10\\\Rightarrow j=30[/tex]
[tex]p=8d=8\times 10\\\Rightarrow p=80[/tex]
So, James is 30 years old, Paul is 80 years old and Dan is 10 years old.

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

The distance between the points R (-1,1) and S (-4,-5) is [tex]3\sqrt{5}[/tex] units.
To find the distance between points R(-1, 1) and S(-4, -5), we can use the distance formula in a coordinate plane.
The distance formula is given by:

Using the given coordinates:
[tex]x_1 = -1, y_1 = 1[/tex](coordinates of point R)
[tex]x_2 = -4, y_2 = -5[/tex] (coordinates of point S)
[tex]d = \sqrt{(-4 +1 )^2 + (-5 - 1)^2}[/tex]
[tex]d = \sqrt{9 +36}[/tex]
