My techer said this would probably be hard for me to answer so i want to prove her wrong i tried putting this into a calculator but it would not work 10(10100) x 27
Answer:
2727000
Step-by-step explanation:
You can calculate it orally.
If numbers are multiplied with 10 we get the same answer as the number but with a zero added at the end . For example 27*10= 270
But if we divide the number ending with a zero with a ten the answer is the same but the zero is removed e.g 1000/10= 100
Similarly you have the numbers
10(10100)*27=
Now breaking the bracket part
10 (1010) 10 *27
100 ( 101)10 *27
1000(2727)
=2727000

Step-by-step explanation:
The Hernandez family orders 3 large pizzas. They cut the pizzas so that each pizza has the same number of slices, giving them a total of 24 slices.
The Wilson family also orders several large pizzas from the same pizza restaurant. They also cut the pizzas so that all their pizzas have the same number of slices. For the Wilson family, the equation y = 10x represents the relationship, where x represents the number of pizzas and y represents the number of total slices.
Which statements best describe the pizzas bought by the Hernandez and Wilson families? Select TWO options.
A. For the Hernandez family, the equation y = 3x represents the relationship between the number of slices and number of pizzas, where x represents the number of pizzas and y represents the number of total slices.
B. For each family, a graph of the relationship between number of pizzas, x, and number of slices, y, goes through the point (0, 0) and is a straight line.
C. The Hernandez family’s slices are smaller than the Wilson family’s slices.
D. If the Wilson family ordered 3 large pizzas from the same restaurant as the Hernandez family, they would have more slices than the Hernandez family after each family cut their pizzas into slices.
E. The constant of proportionality is 10 for the Wilson family, but cannot be determined for the Hernandez family.

Carnival M charges an entrance fee of $7.00 and $0.85 per tocket for the rides. Carnival P charges an entrance fee of $12.00 and $0.35 per ticket for the rides. How many tickets must be purchased in order for the total cost at carnival M and carnival P to be the same?
Answer:
10 tickets must be purchased in order for the total cost at carnival M and carnival P to be the same
Step-by-step explanation:
Let the number of tickets be represented by t
Carnival M charges an entrance fee of $7.00 and $0.85 per tkcket for the rides.
$7.00 + $0.85 × t
= 7.00 + 0.85t
Carnival P charges an entrance fee of $12.00 and $0.35 per ticket for the rides.
= $12.00 + $0.35 × t
= 12.00 + 0.35t
How many tickets must be purchased in order for the total cost at carnival M and carnival P to be the same?
Carnival M = Carnival P
7.00 + 0.85t = 12.00 + 0.35t
Collect like terms
= 0.85t - 0.35t = 12.00 - 7.00
= 0.50t = 5
t = 5/0.5
t = 10 tickets.
Therefore, 10 tickets must be purchased in order for the total cost at carnival M and carnival P to be the same.

The slope of the line for Restaurant B is 2 times greater than the slope of the line for Restaurant A The slope of the line for Restaurant B is 5 times greater than the slope of the line for Restaurant A. The slope of the line for Restaurant B is 10 times greater than the slope of the line for Restaurant A.
Answer: the correct Answer should be B
Step-by-step explanation:
The correct option is slope of the line for restaurant B is 2 times greater than the slope of the line for restaurant A.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Given the values of x and y for restaurant A as,
x : 10 20 30
y : 1 2 3
Consider the point (10, 1) and (20, 2).
Slope of the linear relationship of x and y of restaurant A is,
Slope = (2 - 1) / (20 - 10)
= 1/10
Given the values of x and y for restaurant B as,
x : 25 50 75
y : 5 10 15
Consider the points (25, 5) and (50, 10).
Slope of the linear relationship of x and y of restaurant B is,
Slope = (10 - 5) / (50 - 25)
= 5 / 25
= 1/5
= 2 × 1/10
= 2 × Slope of line for restaurant A
Hence slope of the line for restaurant B is 2 times the slope of line for restaurant A.

A construction company uses 12 pieces of plywood to make 3 sheds. The foreman will be making 6 sheds next week. He first finds the unit rate of how many pieces of plywood he uses per shed by dividing 3 by 12. Then, he multiplies the result by 6 to find how many pieces of plywood he needs for 6 sheds. What was the foreman's error?
Answer:
The foreman's error was he divided 3 by 12 = 3 ÷ 12
The correct step would be to divide 12 by 3 = (12÷ 3)
Step-by-step explanation:
The foreman's error was he divided 3 by 12 = 3 ÷ 12
A construction company uses 12 pieces of plywood to make 3 sheds. The foreman will be making 6 sheds next week.
Hence , the correct calculation is:
3 sheds = 12 pieces
1 shed = x
3 × x = 12 × 1
3x = 12
x = 12/3
x = 4 pieces
1 shed requires 4 pieces of plywood
The unit rate of how many pieces of plywood he uses per shed is 4 pieces per shed
Hence, the correct step would be to divide 12 by 3 = (12÷ 3)
The number of pieces required for 6 shed is 4 × 6 sheds
= 24 pieces of plywood

A bank employee notices an abandoned checking account with a balance of $343. The bank charges an $7 monthly fee for the account. Write the equation that gives the balance F(x) in dollars as a function of the number of months x. (use F(x) in your answer)
Answer:
F(x)=343-7xStep-by-step explanation:
let F(x) be the total amount on the account
and let x be the number of monthly charges
given that
c=$343
the monthly charge is =$7
The expression for the situation is
F(x)=c-mx
F(x)=343-7x
Therefore the expression for the balance is F(x)=343-7x

Answer:
Choice letter C most quickly reveals the y intercept; the y intercept is (0,8).
Step-by-step explanation:
The equations given are all different equations for the same parabola! The one that most quickly provides us with the y intercept is letter C!
Why? Well, letter C is in standard form aka the most basic quadratic formula :
[tex]ax^2+bx+c=0[/tex]
Ironically enough, variable c always states the y intercept in equations as such. Variable c, in this case - is 8. Which means the y intercept is 8!
Now, you'll notice that choice B also mentions + 8 in it's formula, this is true - but in this case it refers to one of the x intercepts (which is actually -8!)
Hope I was of assistance! #SpreadTheLove <3
The y-intercept for the equation is 8, and the equation reveals the intercept most quickly by option C.
What is the function?A mathematical phrase, rule, or law establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
Given a function in three equivalent forms,
to find the y-intercept,
the y-intercept is the point on the y-axis where the value of x is zero,
f(x) = -1/2(x + 3)² + 25/2
f(x) = -1/2(x - 2)(x + 8)
f(x) = -1/2x² - 3x + 8
to find the y-intercept easily the equation should be in form,
ax² + bx + c
where c is the y-intercept,
only 3rd equation is in the form of ax² + bx + c from where y-intercept can be found easily,
f(0) = 8
Hence y-intercept is 8 and with equation f(x) = -1/2x² - 3x + 8 we can calculate it quickly.

Two blueberry farms are similar in shape. The ratio of the side lengths of the farms is 4:5, and the smaller farm has a perimeter of 360 yards. The cost to dig a trench is $0.75 per yard. What is the cost to dig a bench around the larger blueberry farm?
Answer:
$337.50
Step-by-step explanation:
Firstly, we need to get the perimeter of the larger farm.
Since the ratio of the sides of the smaller to
the larger is 4:5, then this will be the ratio of their perimeter too
4/5 = 360/x
4x = 5 * 360
x = (5 * 360)/4
x = 450 yards
Now the cost to dig is $0.75 per yard
For a perimeter of 450, the cost will be 450 * $0.75 = $337.5
This expression is in simplest form: 2y +4x

The half-life of radioactive strontium-90 is 29 years. In 1960, radioactive strontium-90 was released into the atmosphere during testing of nuclear weapons, and was absorbed into people's bones. How many years does it take until only 6% of the original amount absorbed remains?
Answer:
117.7 years
Step-by-step explanation:
We have half life formula,
A=P[tex](0.5)^{\frac{t}{d} }[/tex]
Where ''t'' is number of years
d is half life period.
We know d=29
Where A=6% =0.06
P= 100%=1
Plug in the known values into the formula.
0.06= 1[tex](0.5)^{\frac{t}{29} }[/tex]
Divide both sides by 1.
It gives,
0.06=[tex](0.5)^{\frac{t}{29} }[/tex]
Take log on both sides
log 0.06= [tex]\frac{t}{29}[/tex] log(0.5)
Divide both sides by log 0.5
4.05889 = [tex]\frac{t}{29}[/tex]
Multiply both sides 29
t =117.7079....
Approximately t= 117.7 years.
