Students were discussing what they had learned about minerals. They were debating the similarities of cleavage and fracture. Which group’s statement correctly describes how these two properties are alike?
A. Cleavage and fracture are both used to tell if an object is a mineral.
B. Both of these are properties that can help identify the color and hardness of minerals.
C. These two properties describe how minerals can break.
D. Neither of these properties are as useful as color in identifying mineral types.
The formula for the area of a rhombus with diagonals of lengths c and
d is A = 1/2= cd.
Solve the formula for c.
b. The area of a rhombus is 35 square feet. The length of one of the diagonals is 10 feet. What is the length of the other diagonal?
c. In a square (which is a rhombus), the lengths of the diagonals are the same. If a square has an area of 32 square feet, then what is the length of each diagonal?
Answer: part a.) c =2A/d
Part b.) d = 7
Part C The diagonals are each 8
Step-by-step explanation: part b:
35= 10d/2 70= 10d. 7 =d
Part c 32= 2c²
64 = c²
√64 = √c²
c = 8

Which statement explains whether y = 4x + 8 is a linear function or a nonlinear function?
1. It is a linear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are on a straight line.
2. It is a nonlinear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are not on a straight line.
3. It is a linear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are on a straight line.
4. It is a nonlinear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are not on a straight line.
Answer:
3 (linear)
Step-by-step explanation:
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1
for each of its variables. In this case, the degree of variable y is 1
and the degree of variable x is 1
How do I simplify radicals?
Answer:
Step 1: Find the prime factorization of the number inside the radical. Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Click on the link to see some examples of Prime Factorization. Also factor any variables inside the radical.
Step 2: Determine the index of the radical. The index tells you how many of a kind you need to put together to be able to move that number or variable from inside the radical to outside the radical. For example, if the index is 2 (a square root), then you need two of a kind to move from inside the radical to outside the radical. If the index is 3 (a cube root), then you need three of a kind to move from inside the radical to outside the radical.
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. If there are nor enough numbers or variables to make a group of two, three, or whatever is needed, then leave those numbers or variables inside the radical. Notice that each group of numbers or variables gets written once when they move outside the radical because they are now one group.
Step 4: Simplify the expressions both inside and outside the radical by multiplying. Multiply all numbers and variables inside the radical together. Multiply all numbers and variables outside the radical together.
Example:
Example 1 – Simplify: Example 1
Step 1: Find the prime factorization of the number inside the radical.
252=2*2*3*3*7
Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.
√252= √2*2*3*3*7
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.
2*3√7
Step 4: Simplify the expressions both inside and outside the radical by multiplying.

So i'm having difficulty understanding this "When multiplying the same base raised to an exponent __ the base and __ the exponents" Please help i do not understand this.
Answer:
When multiplying the same base raised to an exponent, keep the base and add the exponents.
Step-by-step explanation:
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.
I hope this helped you understand more!

Rihanna planned a rectangular courtyard for a park and made a scale drawing using inches as the unit of measurement. She originally planned for the length of the actual courtyard to be 54 feet, but she decided to change it to 72 feet. If the length of the courtyard is 18 inches in her scale drawing, which statement about the change of scale is true?
One inch represented 1 foot in the first scale, but now 1 inch represents 4 feet in the second scale.
One inch represented 4 feet in the first scale, but now 1 inch represents 3 feet in the second scale.
One inch represented 54 feet in the first scale, but now 1 inch represents 72 feet in the second scale.
One inch represented 3 feet in the first scale, but now 1 inch now represents 4 feet in the second scale.
Answer: One inch represented 3 feet in the first scale, but now 1 inch now represents 4 feet in the second scale.

Jordan's website was online for a year and received 93,300 visitors. Jordan received 28,400 visitors the first month and 33,900 visitors the second month. How many visitors did Jordan have during the remaining part of the year?
Round each value to the nearest ten thousand to estimate the answer.
Estimate on paper, then check your answer on Zearn.
Jordan had about
30,000 visitors during the remaining part of the year.
Find the exact answer.
Solve on paper.
Jordan had about 30,000 visitors during the remaining part of the year.
Jordan had exactly ______visitors during the remaining part of the year.
Answer:
31,000 visitors
Step-by-step explanation:
Add 28,400 and 33,900 to get 62,300 then subtract that from 93,300
Answer:
31,000
Step-by-step explanation:
28,400+33,900= 62,300.
Take the total amount of visitors (93,300) and subtract 62,300 from that.
That gives you 31,000! Hope that helps:)
