A cell phone company produces 40 defective phones out of every 5000 phones. Another cell phone company produces 30 defective phones out of every 6000 phones. What is the highest number of defective phones do the companies have in common?
Answers
Answer:
10
Step-by-step explanation:
Given that:
Company A:
40 defective out of every 5000
Company B :
30 out of every 6000
To obtain the highest number of defective phones both companies can produce in common :
Factors of :
40 : 2, 4, 5, 8, 10, 20, 40
30 : 2, 3, 5, 6, 10, 15, 30
Hence, highest number of defective phones both companies can produce in common is 10
A high school championship football game was attended by 1580 fans. there were 640 were out of state fans at the game. the other fans were local.
Answers
Answer:
Step-by-step explanation:
1580-640=940 were local
No. of local fans = 940
What is subtraction?Subtraction is one of the four basic arithmetic operations in mathematics. It represents the operation of removing objects from a collection. The minus sign signifies subtraction −.
Example: There are nine oranges arranged as a stack, out of which four oranges are transferred to a basket, then there will be, 9 – 4 oranges left in the stack, i.e. five oranges.
Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5.
Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers such as negative numbers, fractions, rational & irrational numbers, decimals, functions, matrices and vectors.
Given,
Total fans attended championship = 1580
No. of out of state fans = 640
No of local fans = total fans - no. of out of state fans
= 1580 - 640
No of local fans = 940
Hence, there were 940 local fans who attended football championship.

It should be 18 because after subtracting 55 and 54 you get 1 but then you bring down the 9 so you get 19. 18 can only fit to 19 one time, 18x 1, and you get 18. So you subtract 18 and 19 and get 1 then you bring down the 3 and get 13. Answer=18
The Chambers family has driven 603 miles at a constant speed of 67mph. How many hours have they been driving. Use d = rt to solve.
Write an equation for the situation that will represent the distance for any time.
Answers
Answer:
d = 67t
and
eqn d = 67t represents d over time.
Step-by-step explanation:
part one : find the hours they have been driving
d = 603 miles driven
r = 67 mph
t = ?
r = d/t
rt = d
t = d/r
t = 603/67
t = 9
unit = in hours
they have been driving for 9 hours.
part 2 : find an equation for the situation that represents distance for any time
t is the independent variable
d will represent the dependent variable
let r represent the slope
d = rt
d = 67t
therefore the eqn d = 67t represents d over time.

The area of abcd
is 10cm^2 show that x^2 +6x =1
Answers
Answers
Maths
GCSE
Article
The area of square ABCD is 10 cm^2 . Show that x^2 + 6x = 1 (requires diagram which I will draw on the whiteboard).
The area of a square is the length of one side squared (multiplied by itself), so for a square with side length 3, the area will be 32 or 3 x 3, which = 9. For a square with side length x, the area will be x2 .Given that the length of one side is 3 + x, the area will be (3+x)2 This can be written as (3+x) * (3+x), and to expand these brackets we will use the 'crab claw' method. We will take the first value in the first bracket, and times it by both values of the second bracket. So we will multiply 3 by 3 which is 9, and then 3 by x which is 3x. We will then take the second value in the first bracket and multiply is by both values in the second bracket. So we will multiply x by 3 which is 3x, and then x by x, which is x2. Now we will add together all the the values we have just found: x2 + 3x + 3x + 9. Because the only like terms are 3x and 3x, and 3x + 3x = 6x, the final equation we form after expanding the brackets will be x2 + 6x + 9.. Given that the area of the square is given as 10cm2, 10 must be equivalent to x2 + 6x + 9, so we form the equation x2 + 6x + 9 = 10. When balancing equations, you must do whatever you do on one side to the other side. Therefore if we take 9 away from the left hand side, we must take 9 away from the right hand side (10 - 9 = 1), leaving us with x2 + 6x = 1, and completing the question.

Everyday Isabel swims 10-20 laps in a 50 meter pool. The amount of time she spends swimming is represented by the function f(x) = 3x where x represents the number of laps she swims.
Answers
Given :
Everyday Isabel swims 10-20 laps in a 50 meter pool.
The amount of time she spends swimming is represented by the function f(x) = 3x .
To Find :
The speed of Isabel.
Solution :
Distance travelled in x laps is, D = 50x .
It is given that time taken is, t = 3x .
So, speed of Isabel is given as :
[tex]Speed=\dfrac{Distance}{Time}\\\\Speed = \dfrac{50x}{3x}\\\\Speed = \dfrac{50}{3}=16.67 \ m/s[/tex]
Hence, this is the required solution.
What is the Greatest Common Factor of the two monomials?
15a²b, 35ab2
Answers
Answer:
5ab
Step-by-step explanation:
To find the greatest common factor (GCF), you will need to find the largest value that both of these monomials can be divided by. There are three different parts to these monomials: the number value, variable a, and variable b.
Find the largest number of each element that can be divided by both.
Numbers: the GCF of 15 and 35 is 5 (15/5 = 3, 35/5 = 7, 3 and 7 are prime numbers and therefore, cannot be divided further)
Variable a: the GCF of a² and a is a
Variable b: the GCF of b and b² is b
Therefore, the GCF is 5ab.

The value of the given expression 5² + 2³ is 33
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
The given expression, 5² + 2³, involves two operations: squaring and cubing.
The first operation, 5², means that we need to multiply 5 by itself, which results in 25.
The second operation, 2³, means that we need to multiply 2 by itself three times, which results in 8.
Therefore, 5² + 2³ is equivalent to 25 + 8, which gives us 33 as the final answer.
In other words, the value of the given expression is 33. This calculation involves basic arithmetic operations and can be easily solved using a calculator or mental math skills.
