Answer:
56 problems
Step-by-step explanation:
So we already know that the answer is: 56. However, a good help is knowing how to obtain this answer from the data provided.
Tony's quiz had 80 questions
Tony correctly answered 70% of them.
We can always write a percentage amount as a ratio by dividing the amount by 100.
.
This means that for every 100 questions, tony will respond correctly 70.
So, if Toni did a questionnaire of n questions, the amount that will answer correctly is calculated by the following expression:
If 
then:
Answer:
the equation is wrong
Step-by-step explanation:
=> 74-25=59
since 74 - 25 equals to 59 in order to find the addition sentence that will check the subtraction problem is true and 59 and 3/5 or you can add add 59 and 25 to check if the problem was solved correctly
=> 59+25
add 59 to 25
=> 84
this means the question is wrong
Answer:
D. g(x) = 3·x²
Step-by-step explanation:
The given parent function, f(x) = x²
The graph of the function, g(x) is narrower than the graph of the function f(x)
Therefore, the coefficient of the quadratic function is larger than 1
The given point on the parabola, g(x) = (1, 3)
Therefore. when x = 1, g(x) = 3
However, when x = 1, f(x) = 1
Therefore, given that g(x) = a·f(x), we get;
a = g(x)/(f(x)) = 3/1 = 3
g(x) = 3·x²
Answer: B
Step-by-step explanation: what I did was I drew a square and folded it if both sides matched i knew that that was a line of symmetry
This equation of the recipe can be represented as y = x + 5.5 and The constraints are x is ≥ 0 and y is ≥ 5.5.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Otto used 5.5 cups of whole wheat flour and x cups of white flour in the recipe.
The total amount of flour (y) = the total amount of whole wheat flour (5.5) + the total white flour (x).
Therefore, the equation is:
y = x + 5.5
The possible values are
x = 0 or greater to it since the minimum amount of white flour that can be added is 0.
y = 5.5 or greater to it since even if no
white flour is added the minimum total is 5.5.
