Step-by-step explanation:
Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.
what is the fraction for the right handed people
Answer:
Step-by-step explanation:
12% is equivalent to 12/100. This reduces to 3/25. Thus, 3/25ths of the students are left-handed. The corresponding fraction for the right handed people is (25-3)/25, or 22/25ths. There are more right-handed people (22/25ths) versus left-handed people.

That's the biggest number
Answer: B
Step-by-step explanation:
In this problem we know that the Acme Nails made 55,672 and the problem is asking who made more. Knowing this we now know we need to find a number higher then 55,672.
A is incorrect because it is less the 55,672 and same goes for C and D
B is correct because 55,674 is 2 more then 55,672
I hope this helps have a great day and merry Christmas :)

What is the range of possible sizes for side x? _ < x < _
Answer:
0.5 < x < 16.5
Step-by-step explanation:
The third side of the triangle must be longer than the difference of the other two sides:
x > (8.5 -8.0)
x > 0.5
And it must be shorter than their sum:
x < (8.5 +8.0)
x < 16.5
The third side must be in the range ...
0.5 < x < 16.5
_____
These limits are a direct consequence of the triangle inequality, which requires the sum of the two shortest sides exceed the length of the longest side.
Which of the following equations results in no solutions?
A 3(v + 5) = 2v - 4 + v
B 3(v + 5) = 2v + 15 + v
C 3(v + 5) = 2v + 15
D 3(v + 5) = 2v - 4

Tony usually saves 1/5 of his allowance. Last week, he only saved 2/3 as much. How much of his allowance did he save last week?
Answer:
2/15
Step-by-step explanation:
All we have to do is multiply 1/5 by 2/3
1 x 2 = 2
5 x 3 = 15
Therefore, Tony saved 2/15 of his allowance last week.
Answer:
2/15
Step-by-step explanation:
you have to multiply 1/5 by 2/3
1 x 2 = 2
5 x 3 = 15
Therefore, Tony saved 2/15 of his allowance last week.
Grant mows lawns for extra money. He mows 9 lawns in 9 hours on Wednesday and 6 lawns In 6 hours on Saturday.
What is the constant of proportionality that relates the total number of lawns mowed, y, to the number of hours mowing lawns, x?
Answer:
the constant is 1. 9/9 is the same as 1. so 9hours over 9 lawns is 1.
Graph the solution to this inequality on the number line. −1/3x + 1/2 ≥ −3/4
Answer:
4.5 (4.5 units to the left of 0) Make sure to draw a solid dot over 4.5 and an arrow pointing in the right direction.
>= is the greater than or equal to symbol
Step-by-step explanation
1. Combine like terms- In this problem, the like terms are 1/2 and -3/4, so to move 1/2 over to the other side of the equation, we have to divide each side by 2/1, which is the same as multiplying each side by 2: -1/3x + 1/2 * 2 >= -3/4 * 2.
2. Separate the fraction from x- Now, we simply divide each side by -3/1, which is the same as multiplying each side as -3: -1/3x * -3 >= -3/2 * -3
3. Graph on the number line- We've found that x = 4.5. To check, substitute in 4.5 for the value of x: -1/3(4.5) + 1/2 >= -3/4. -1 >= -3/4 is a true inequality. To graph it on the number line, draw a solid dot over 4.5 and an arrow in the direction of the righthand side.

Step-by-step explanation:
How do you evaluate fractions with whole numbers?
Multiply a fraction with a whole number by multiplying only the numerator. For example, 5 x 1/8 = 5/8. Multiply a fraction with another fraction by multiplying the numerators together and the denominators together. For example, 3/8 x 2/5 = 6/40 = 3/20.

12. Multiply the following binomials:
a. (x + 3)(x - 4)
b. (s - 2)(2s - 12)
c. (4s - 12)(2s + 4)
d. (2x - 4)(2x - 4)
Answer:
a) x^2 - x -12
b) 2s^2 - 16s + 24
c) 8s^2 - 8s -48
d) 4x^2 - 16x + 16
Answer:
a. x^2 - x - 12
b. 2s^2 - 16s + 24
c. 8s^2 - 8 - 48
d. 4x^2 - 16 + 16
Step-by-step explanation:
You need to use distributive property find the answer.
(x + 3)(x - 4)
>> (x)(x) = x^2
>>(x)(-4) = -4x
(3)(x) = 3x
(3)(-4) = -12
The result will be x^2 -4x + 3x -12
You can simplify this by adding the like terms:
x^2 -4x + 3x -12
>> x^2 - x - 12
Just do the same for the rest of them by using distributive property.
Hope this helps! Have a great day! Also, let me know if you need an explanation for the rest of them too!
Jaylen's beta fish tank holds 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. What is the flow rate of the water in gallons per minute? (label your answer gpm) pls dont delete or post links Ty worth 29 points and brainlyiest
I had this same question! ill tell you what i got.
Answer:
12/5
Step-by-step explanation:
His fish tank is 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. So you need to find out how many gallons you can pour in 1 minute. You can eliminate A (5/12) because he is filling more than 1 gallon per minute. You can divide 4.5 (4 1/2) by 1.875 (1 7/8). You get 2.4. Convert it back to a fraction, and you get 2 4/10. Simplify the fraction 2/5. Now convert it to an improper fraction. 12/5.

HOW DO YOU FIND RADIUS
Answer:
you can divide the diameter by 2 or divide the circumference by 2pi
Step-by-step explanation:
If the circumference of a circle is given:
Let the radius be r.Say, that the circumference is given as C.By using the formula,[tex]2\pi \: r = C \\ = > r = \frac{C}{2\pi} [/tex]So, to find radius of a circle when circumference is given, we have to divide the circumference with 2π. Then, we will get the radius of the circle.Note : You have to consider π as 22/7 or 3.14. Or the value will be given in the question.If the diameter of a circle is given:
Let the radius be r.Let the diameter be D.By using the formula,2r = D[tex] = > r = \frac{D}{2} [/tex]Hence, if the diameter of a circle is given, we have to just divide the diameter with 2. Then we will get the radius of the circle.Hope you could get an idea from here.
