Answer:
The radius is 6.
Step-by-step explanation:
If you have a diameter, you simply divide it by 2. so 12/2 is 6. Hope it helps :)
by rounding each number to 1 significant figure, estimate the answer to 623 - 14.71 ÷ 0.54.
623 to 1 significant number = 600
14.71 to 1 significant number = 10
0.54 to 1 significant number = 0.5
answer:
[tex]\tt \dfrac{600-10}{0.5}=1180[/tex]
Anna selects a positive multiple of 4 that is less than forty, and Becky selects a positive multiple of 3 that is less than sixty. What is the probability that they pick the same number?
I will mark brainliest!
Answer:
3/171
Step-by-step explanation:
The problem can be simplified into finding probability that Anna and Becky select 12 or 24 or 36 which are less than 40 and multiples of 3 and 4.
Probability of Anna selecting 12 = 1/9
Probability of Becky selecting 12 = 1/19
Probability of Anna and Becky selecting 12 = 1/9 * 1/19 = 1/171
Probability of Anna and Becky selecting 12 or 24 or 36 = 3* 1/171 = 3/171

In a school 50% of the students are younger than 10, 1/20 are 10 years old and 1/10 are older than 10 but younger than 12, the remaining 70 students are 12 years or older. How many students are 10 years old?
Answer:
10 students
Step-by-step explanation:
Given :-
50% younger than 10
1/20 (or 5%) are 10
1/10 (or 10%) are older than 10 but younger than 12
Remaining students = 100% - 50% - 10% - 5%
= 35%
= 70 students
Total students
=> 7T/20 = 70
=> 7T = 1400
=> T = 200
10 year old students
= T x 5%
= 200 x 1/20
= 10 students
Given :
[tex]50\%[/tex]younger than [tex]10[/tex]
[tex]\frac{1}{20} [/tex](or 5%) are 10
[tex]\frac{1}{10}[/tex] (or 10%) are older than 10 but younger than 12

A circle has a radius of 10 mm. What is its circumference?
Answer: 20pi mm
Step-by-step explanation:
The circumference of a circle is 2*pi*radius.
Therefore, the circumference is 2*pi*10mm = 20pi mm
Answer/s:
≈ 62.83 mm or 20π mm
Step-by-step explanation:
We can use the following formula to solve:
C = 2πr
C = 2π(10)
C ≈ 62.83 mm

Marcus plants daffodils in 6/10 of his garden and sunflowers in 11/100 of his garden. Which addition equation shows how to find the total fraction of the garden in which Marcus planted daffodils and sunflowers.
Answer:
71/100 of Marcus' garden is daffodils and sunflowers.
Step-by-step explanation:
To add fractions, the denominators need to be equal. So, 6/10 -> 60/100. 60+11=71, keep the 100. 71/100. Hope this helps!

What equation represents the line shown:
Answer: B) y=-3x+2.
Step-by-step explanation:
+2 is where the line touches on the y axis. and for -3. you find 2 points and you go from 1 point to the other. the points i got were. (0,2) (2,-4). i went down 6 times, and to the right 2. that’s a fraction 6/2. and then simplify. 2 can go into 6 three times, and can go into 2 once. 3/1. since there’s a 1 underneath it’s just 3. and since you went down. it’s is negative. so y=-3x+2 is your answer.
Evaluate 8w - 2p if w = 6 and p = -5
Known facts
w = 6p = -58w - 2p = 8(6) - 2(-5) = 48 + 10 = 58
Answer: 58
Hope that helps!
Answer:
58
Step-by-step explanation:
Knowing that w = 6 and p = -5
Thus, equation look like this:
8(6)-2(-5)
Now Let's Multiply:
8(6)=48 and -2(-5) = 10 [ (-) + (-) = (+) and (+) +(+) =(+)
48 + 10 = 58
Answer = 58

3/4+__=2
WHATS THE ANSWER
Answer:
The answer is 5/6.
Step-by-step explanation:
Lets start with a=1.
a+1=2, which is the denominator. (1/2)
Taking the same number as numerator, now, consider a=2.
a+1=3, denominator.(2/3)
Now, let a=3.
a+1==4, denominator for a=3. (3/4)
If continued a becomes equal to 4.
a+1=5, which is also the denominator. (4/5)
Now, since the denominator is 5, let a=5.
a+1=6, which will become the denominator. (5/6)
Thus the series follows a pattern of a/a+1.
Answer:
5/4
Step-by-step explanation:
Let's put the unknown value as X
To solve this equation, we must solve for x
First we need to isolate x, which means we need to get it by itself.
To do this, we must subtract 3/4 on both sides since it is being added.
This gets rid of 3/4 on the first side and changes the second side to whatever 2+3/4 is
This leaves us with x=5/4
Therefore, your answer is 5/4.

Which of the following equations does not represent a linear relationship between x and y
A.y=4x
B.y= 2x^2 + 5x
C. 5x= 3(Y - 2)
d. 6x - 7y = 13
A linear relationship is an equation that has a constant slope
The equation that does not represent a linear relationship is (b) y = 2x^2 + 5x
How to determine the non-linear relationshipA linear equation can take any of the following forms:
y = mx + b
y - y1 = m(x - x1)
Ax + By = c
Any form different from the above forms is not a linear equation
Using the above format as a guide, the equation that does not represent a linear relationship is (b) y = 2x^2 + 5x

what is the value of x?
Answer:
x = 10
Step-by-step explanation:
All angles in a triangle must add up to 180. We know one angle is 68 and another is 90 because there is a right angle (which are always 90).
180 = 90 + 68 + (2x + 2)
180 = 158 + (2x + 2). subtract 158 from both sides
22 = 2x + 2. subtract 2 from both sides
20 = 2x. divide both sides by 2
10 = x
Answer:
x = 10
Step-by-step explanation:
2x + 2 + 68 + 90 = 180
2x + 160 = 180
2x = 20
x = 10

Simplify:
Answer:
Step-by-step explanation:
2) a(a + b) + b(a - b) - 2ab / a² - b²
= a² + ab + ab - b² - 2ab / a² - b²
= a² - b² / a² - b²
= 1
3) [x - 1/(x - 1)(x - 2)] + [x - 2/(x -2)(x - 3)]
= (1 / x - 2) + (1 / x - 3)
= x - 3 + x - 2 / (x - 2)(x - 3)
