How does estimating an addition or subtraction problem help you know if ananswer is reasonable?
Answer:
To be reasonable means to be as much as is appropriate or fair.
In math, reasonableness can be defined as checking to verify that the result of the solution or the calculation of the problem is correct or not, be either estimating or by plugging in your result to check it.
When solving a math problem, we can check if the answer we have derived to is reasonable or not, based on an estimate. A reasonable estimate does not exceed the original numbers in a problem.
For instance, in a division problem like 424 ÷ 4 − 10, we can check is our answer is reasonable or not, by estimating an approximate answer or by plugin gin using the division formula.
We can round down 424 to the nearest hundreds, to estimate the answer. Since 96 (actual answer) ≈ 90 (estimate answer), we know our solution is correct.
We can check our solution by plugging in to verify using, 96 × 4 + 10 as well.
Step-by-step explanation:
When estimating an addition or subtraction problem, you can easily tell if it is reasonable or not. If you're having trouble with a problem, such as 1342+7864, and you're getting an answer of... 1300, but don't think its correct, you can estimate by rounding the numbers and adding them. For example, 1342=1300 and 7864=7900 (I'm using the rule that if the number is 4-0 I round down and if its 5-9 I round up.) Since we're woring with thousands you would try to get the most split, even value you can without taking off too much, so we would round the tens place. And after that you could add 1300+7900=9200. Then you would know your answer of 1300 is not reasonable and you have an error in your equation. Estimating is a great skill to have, and it really helps when you're just trying an equation out or get one of those "Estimate the sum of" questions.

The function f(x) = −x2 + 60x − 116 models the monthly profit, in dollars, a shop makes for repairing windshields, where x is the number of windshields repaired. Determine the vertex, and explain what it means in the context of the problem. (30, 784); The vertex represents the maximum profit.
(30, 784); The vertex represents the minimum profit.
(2, 58); The vertex represents the maximum profit.
(2, 58); The vertex represents the minimum profit.
Answer:
Even tho the answer is not up there but its
(30, 784); The vertex represents the maximum profit.
Step-by-step explanation:
....
For the quadratic equation f(x) = -x^2 + 60x - 116, the vertex is (30, 784), and it is a maximum.
How to get the vertex?
For a general quadratic equation:
y = a*x^2 + b*x + c
The vertex is at the x-value:
h = -b/2a
To get the y-value, we evaluate the quadratic equation in h.
In our case, we have:
y = -x^2 + 60x - 116
Then:
h = -60/(2*-1) = 30
To get the y-value of the vertex, we evaluate in x = 30.
y = -(30)^2 + 60*30 - 116 = 784
And, as you can see, the leading coefficient of the quadratic equation is negative. This means that the arms open downwards, so the vertex is a maximum.
Then, concluding, the vertex is (30, 784), and it is a maximum.

The amount of icing on a Cuppie Cake large cupcake follows a Normal distribution, with a mean of 2 ounces and a standard deviation of 0.3 ounce. A random sample of 16 cupcakes is selected every day and measured. What is the probability the mean weight will exceed 2.1 ounces?
Answer: the probability the mean weight will exceed 2.1 ounces is 0.09
Step-by-step explanation:
Let x be the random variable representing the amount of icing on a Cuppie Cake large cupcake. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = standard deviation
n = number of samples
From the information given,
µ = 2
σ = 0.3
n = 16
x = 2.1
the probability that the mean weight will exceed 2.1 ounces is expressed as
P(x ≥ 2.1)
For x = 2.1
z = (2.1 - 2)/(0.3/√16) = 1.33
We would determine the probability for the area above z = 1.33 from the normal distribution table. It would be
p = 1 - 0.91 = 0.09
P(x ≥ 2.1) = 0.09

A restaurant offers four sizes of pizza, two types of crust and eight toppings how many possible combinations of pizza with one topping are there
Answer:
64
Step-by-step explanation:
You know that:
there are four different sizes of pizza
two types of crust
and eight toppings
With a one-topping pizza, all you have to do is multiply 4 by 2 and then by 8
If it helps to branch it all out so you can visually see it, that would be a great idea
But in short, 4x2x8 is 64, so there are 64 combinations
:)
Final answer:
The number of possible pizza combinations with one topping is 64, calculated by multiplying the number of sizes, crust types, and toppings available, which are 4, 2, and 8 respectively.
Explanation:
To determine the number of possible combinations for a pizza with one topping, we apply the Fundamental Principles of Counting and use the Multiplication Principle.
Since there are four sizes of pizza, two types of crust, and eight toppings, we multiply these numbers together.
The calculation would be as follows:
Number of sizes = 4Number of crust types = 2Number of possible single toppings = 8Therefore, the number of possible pizza combinations with one topping is:
4 (sizes) x 2 (crust types) x 8 (toppings) = 64 combinations.

Yes, because 3/4 is bigger then 1/2 so there is more then 1 in there. The expression 1/2 divided by 3/4 is smaller then 1 because 3/4 is already bigger so you can't fit one in. Without using fractions it is like 3/2 is bigger then 1 since 2 is smaller then 3. 2 divided by 3 is less because 3 is bigger so you can't fit the 3 in a 2.

d) I the length of the cable from L to E is 80 feet, E to the ground is 35 feet, and F to the ground is 40
feet, what is the length of the cable from Jto F?
The length of the cable from J to F is calculated by adding the length of the cable from L to E to the length from E to F which is difference in distance to the ground from E and F. The total length of the cable from J to F is 85 feet.
Explanation:
In this problem, we need to determine the length of the cable from J to F. To solve this, we will be using the principles of geometry. The cable from L to E to F forms a triangle. We know that the distance from L to E is 80 feet and that from E to F can be determined by subtraction, given that the distance from E to the ground is 35 feet and from F to the ground is 40 feet. From this information, we can get that the length from E to F is 5 feet. The total length from L to F (through E) is 80 feet + 5 feet, which equals 85 feet. Therefore, the length of the cable from J to F is 85 feet.

Step-by-step explanation:
The vertex means that the maximum amount of candles that you can sell is exactly 8 to obtain full profit.
The equation would be f(x) = -X² + 16x - 60
then -(x^2 -16x)-60 which then equals
-(x^2-16x+64-64)-60
then that would equal -(x-8)^2 +64 -60
