Annika needs to sell at least 25 boxes of Girl Scout cookies to get a new badge she has already sold 4 boxes how many more does she need to sell one
step inequality word problems
Answer:
21
Step-by-step explanation:
Maggie has $16 to spend on lunch for the week she has already spent four dollars which inequality statement shows how much more money Maggie has left to spend for the week
Answer:
x ≤ $12
Step-by-step explanation:
Since Maggie has $16 to spend for the week, she can spend less than $16 or exactly $16. Thus, the inequality used would be ≤, which can be read as 'less than or equal to'.
Let the amount of money she has left to spend for the week be x.
Total spending for the week ≤ $16
$4 +spending for the rest of the week ≤ $16
$4 +x ≤ $16
Subtract both sides by $4:
x ≤ $16 -$4
x ≤ $12

Describe how to determine the average rate of change between x = 1 and x = 3 for the function f(x) = 3x3 + 1. Include the average rate of change in your answer.
Answer:

Step-by-step explanation
Average rate of change of a function is determined using the formula, Given the function, f(x) = 3x³ + 2To find the average rate of change between x = 3 and x = 5, let:a = 3f(a) = f(3) = 3(3)³ + 2 = 83b = 5f(b) = f(5) = 3(5)³ + 2 = 377Plug in the values into the formulaAverage rate of change =
48+36 written as a product of two factors
48 + 36 written as a product of two factors gives; 12 × 7
How to rewrite product of numbers?We are given the function;
48 + 36
Let us pick the largest common factor of both numbers which is 12 and so we will factorize to have;
12*4 + 12*3
⇒ 12(4 + 3)
⇒ 12 * 7
Thus, the correct answer is 12 * 7

Which of the following represent the values of x, y, and z to the nearest hundredth?
Answer:
Step-by-step explanation:
y² = 5.66 × 5.66 ⇒ y = 5.66
x = z = 5.66√2 ≈ 8.00
The values of x, y and z in the given triangle are 8, 5.66 and 8.
What are triangles?Triangles are a type of a polygon having three sides and angles.
Given is a triangle, having some unknown variables, we need to find their values,
So,
According to the figure we can say that the triangle is an isosceles triangle because the median is perpendicular to the base and dividing it into equal parts.

5/12 and 4/18
Answer:
5/12 = 15/364/18 = 8/36Step-by-step explanation:
The least common denominator can be found as the product of the denominators, divided by their greatest common factor:
LCD = (12)(18)/6 = 36
This is 3 times 12, so
5/12 = (5/12)(3/3) = 15/36
and it is 2 times 18, so
