A piece of string has been used to measure the circumference of a circle. Use a ruler to measure the diameter of the circle and the length of the string to the nearest 1/4 inch
Answer:
The circumference is expressed usingC=2πrStep-by-step explanation:
This problem is on the mensuration of flat shapes, a circle.
The length of the string corresponds to the circumference of the circle.
The lenght of the string can be calculated by using the expression for circumference, if after using the ruler to obtain the diameter "d"
upon measuring the diameter we can further obtain the radius "r"
The expression for the radius is r=d/2 (the radius is half the diameter)
C=2πr
where pi= 3.124 a constant term
Hence Circumference is the same as the length of the string
Frank earns $8 per hour. Madison
earns $7.50 per hour. Frank started working after Madison had already earned $300. If these rates continue, will Frank’s earnings ever equal Madison’s earnings? If so, when?
Answer:
yes, and at 600 hours they are equal and at 601 Frank passes her.
Step-by-step explanation:
since frank has a higher salery/slope and Madison has a lower salary slope meaning even though Madison started out with more Frank will eventually pass her.
First, you gotta find the difference slope 8-7.5 so .5 then find the difference in starting points 300 and zero. then multiply the difference as a positive(make it reversed 1/2 to 2/1 ) so 2 times 300 equals 600.
Answer:
They will and it will be by the 600th hour. The equation is frank makes 8$ dollars per hour for n hours. That (at some point) is the same as what maddi makes, 7.50 per hour for n hours plus 300... sooo
8n=7.50n+300
Sub in n for 600 and it should cancel everything out and work :)

A bag contains 36 calculators. This number is 75% of the number of calculators that can fit in the bag. How many calculators can the bag hold when filled?
Answer:
48
Step-by-step explanation:
Let X represent the total number of the calculator, then we can form an equation from the explanation of the question as
X × 75/100=36
75x=36×100
Making X the subject of the formula we have,
X=3600/75
X=48
Hence, 48 calculators can the bag hold when filled

We can clearly see in the diagram that a transversal is intersecting two parallel lines.
When a transversal intersects two parallel lines, eight angles are formed.
The angles which are in the same position on same side of each line intersected by the transversal, are called corresponding angles.
Corresponding angles are congruent.
So,
Angle 6x+4° and 100° will be congruent or equal
[tex]6x+4 = 100\\6x =100-4\\6x = 96\\\frac{6x}{6} = \frac{96}{6}\\x = 16[/tex]
Hence,
The value of x is 16

Enter your answer by filling in the boxes.

Answer:
x = 1 , y = 34
x = 2 , y = 38
x = 3 , y = 42
x = 4 , y = 46
x = 5 , y = 50
Step-by-step explanation:
The solution for the equation at different values is given below:-
x = 3 , y = 42
x = 4 , y = 46
x = 5 , y = 50
What is a linear equation?A linear equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that the equation is y= 4x +30. From the table, the value of y at different values of x will be:-
x = 3 , y = ( 4 x 3) + 30 = 12 + 30 = 42
x = 4 , y = ( 4 x 4 ) + 30 = 16 + 30 = 46
x = 5 , y = ( 4 x 5 ) + 30 = 20 + 30 = 50
Therefore, the solution for the equation at different values is at x = 3 , y = 42 then at x = 4 , y = 46 and, at x = 5 , y = 50.

Car Survey in a survey of 1,800 people who owned a certain type of car, 1,080 said they would buy
that type of car again. What percent of the people surveyed were satisfied with the car?
Answer: 60%
Step-by-step explanation:
First you have 1,080 satisfied out of 1,800.
Then you divide 1,080/ 1,800.
When you divide you get .6
Finally move the decimal 2 places to the right and you get 60 which is 60%.

Step-by-step explanation:
Given
g(x) = 2x² - 6x - 56 ← factor out 2 from each term
= 2(x² - 3x - 28) ← factor the quadratic
Consider the factors of the constant term (- 28) which sum to give the coefficient of the x- term (- 3)
The factors are + 4 and - 7, since
4 × - 7 = - 28 and 4 - 7 = - 3 , thus
x² - 3x - 28 = (x + 4)(x - 7) , then
g(x) = 2x² - 6x - 56 = 2(x + 4)(x - 7) → B

Answer:(2,-9)
Step-by-step explanation:
A number divided by 42 has a quotient of 28 with a remainder of 4. What is the number?
O 1,064
o 1,172
O 1,176
O 1,180
Answer:
D. 1,180
Step-by-step explanation:
Given the following data;
Divisor = 42
Quotient = 28
Remainder = 4
A quotient of 28 simply means that a number divided by 42 would have a value that is equal to 28 without any remainder.
Let the unknown number be X
X = (42*28) + 4
X = 1176 + 4
X = 1180.
Method II
Y/42 = 28
Cross-multiplying, we have;
Y = 28 * 42
Y = 1176
Given that the remainder is 4
X = Y + 4
X = 1176 + 4
X = 1180.
Therefore, the number is 1180.
