Answer:
"I think there are a whole bunch of points that are 3 units away from (-5, 0)". Lin's statement is correct.
Step-by-step explanation:
from the question, the point has a coordinate (-5, 0) which can be plotted on a Cartesian plane to show its location or position. A Cartesian coordinate is a system that consists of two perpendicularly intersecting axis used for plotting of the locations or positions of given points.
There are a whole bunch of points that are 3 units away from (-5, 0) because real numbers that are 3 units away are more than 4. Real numbers consists of all rational numbers, fractions and irrational numbers. So if all real numbers that are 3 units away from (-5, 0) are plotted, then the points would be more than 4.
Therefore, Lin's statement is correct.

We need two numbers that...
Add together to get 12
Multiply together to get 27
Can you think of the two numbers?
Try 3 and 9:
3+9 = 12
3*9 = 27
Fill in the blanks in

Answer:
3
Step-by-step explanation:
From the information given in the statement, you can find the number of problems that Hunter answered correctly by calculating the 5% of 60. This because 5% is the grade that he got which means that he only had 5% of his answers correctly and 60 is the total number of problems:
60*5%= 3
According to this, Hunter answered correctly 3 problems on the final exam.
Rowan is taking his siblings to get ice cream. They can't decide whether to get a cone or a cup because they want to get the most ice cream for their money. If w = 4 in, x =6 in, y = 6 in, z = 2 in, and the cone and cup are filled evenly to the top with no overlap, which container will hold the most ice cream? Use 3.14 for π, and round your answer to the nearest tenth.
a cone with a height of x and a radius of w, a cylinder with a diameter of y and a height of z
please help me
The cone holds 44 cubic inches more ice cream than a cup.
Important information:
Height of a cone is x =6 in and radius w = 4 in.Diameter of a cylinder is y = 6 in and height z = 2 in.We need to find the volumes of each ice cream container.
Volume:Volume of the cone is:
[tex]V_1=\dfrac{1}{3}\pi r^2h[/tex]
[tex]V_1=\dfrac{1}{3}(3.14) (4)^2(6)[/tex]
[tex]V_1=100.48[/tex]
The diameter of the cylinder is 6 in so the radius is 3 in.
Volume of the cylinder is:
[tex]V_2=\pi r^2h[/tex]
[tex]V_2=(3.14)(3)^2(2)[/tex]
[tex]V_2=56.52[/tex]
Clearly [tex]V_1>V_2[/tex].
[tex]V_1-V_2=100.48-56.52[/tex]
[tex]V_1-V_2=43.96[/tex]
[tex]V_1-V_2\approx 44.0[/tex]
Therefore, the cone holds 44 cubic inches more ice cream than a cup.

A math teacher randomly selects one student in a class to write a probability question on a chalkboard. The teacher then randomly selects a different student to answer the probability question. There are 18 boys in the class, and the ratio of boys to girls is 3:5. Find the probability that the teacher selects a girl first and a girl second. Write your answer as a decimal rounded to the nearest thousandth.
Answer:
The probability to the nearest thousandth is 0.386
Step-by-step explanation:
Firstly, we will need to know the number of girls and the total number of students in the class.
We have the ratio as 3:5 for boys and girls with the number of boys being 18
What we have is thus;
3:5 = 18:g
3/5 = 18/g
3g = 90
g = 90/3
g = 30 girls
Thus, we have 18 boys and 30 girls with a total of 48 students.
The probability that the teacher selects a girl to write the question on the board is 30/48 = 5/8
Now, we intend selecting another girl to answer the question. This is like a probability without replacement. So this means that the number of girls we have now is 29 and the number of students we are selecting from is 47 students
Thus, the probability of selecting a girl to answer the question becomes 29/47
The joint probability is thus; 29/47 * 5/8 = 145/376 = 0.3856
To the nearest thousandth, we have 0.386

Given DOG, find DG.
Round your answer to the nearest hundredth.
Answer:
DG = 31.75
Step-by-step explanation:
The question is incomplete; however, I'll answer your question using attached image.
From the attachment,
<G = 72° and DO = 8.2
Required
DG?
To get the length of side DG, We have to look for a trigonometric ratio that relates DG, DO and <G together.
DG represents the hypothenus of the triangle;
DO represents the opposite of the triangle;
The two sides are bound by the sine function.
i.e.
Sin72° = DO/DG
Sin72° = 8.2/DG
Multiply both sides by DG
DG * Sin72 = 8.2/DG * DG
DG * Sin72 = 8.2
Sin72 = 0.2538
So, DG * Sin72 = 8.2 becomes
DG * 0.2538 = 8.2
Divide both sides by 0.2583
DG * 0.2583/0.2583 = 8.2/0.2583
DG = 8.2/0.2583
DG = 31.746031746
DG = 31.75 --- Approximated
The family size bottle of shampoo holds 10 fluid ounces (fl. oz.) of sunscreen. The regular bottle holds 70% percent less. How many fluid ounces does the regular bottle of shampoo hold?
Answer: 3 fluid ounces
Step-by-step explanation:
The family size bottle of shampoo holds 10 fluid ounces of sunscreen while the regular bottle holds 70% percent less.
To get the fluid ounces the regular bottle of shampoo will hold, we find 70% of 10 fluid ounces and them subtract from 10 fluid ounces. This will be: = 70% of 10 ounces
= 7/10 × 10
= 7 fluid ounces.
Since the regular holds 70% less, week subtract 7 fluid ounces from 10 fluid ounces. This will be:
= 10 ounces - 7 ounces
= 3 ounces.
The regular bottle of shampoo holds 3 fluid ounces.
