Answer:
associative property
Step-by-step explanation:
identity property is when you multiply one by any number and get the number you multiplied by. for example, 1x3=3; 1x7=7. Commutative property has to do with the order of multiplication being rearranged. and distributive property multiplies a number outside the parentheses into the numbers inside. all that's left is the associative property which indicates that addition can be rearranged and still get the same answer. hope this helps :)
A right triangle is ____ a scalene triangle.
Always, sometimes, or never
Answer: Sometimes
Step-by-step explanation:
This is a very tricky question. We know that in an isosceles triangle, two sides are the same. Because of this, we know that the right angle is always 90 degrees, and the other sides would be 45 degrees each because all triangles add up to 180 degrees. A right triangle could also be scalene, meaning none of the sides are the same, for example a scalene triangle could have sides of 44, 46, and 90 degrees. Rest assured, a right triangle will never be equalateral. Hope this helps :) Merry Christmas

write as a single fraction in its simplest form 2x -1 / 3 - 2/x + 1
Answer:
(2x^2 + x-7)/3x+ 3
Step-by-step explanation:
Here, we want to write the following as a single fraction;
2x-1/3 - 2/x + 1
That will be;
(2x-1)(x + 1) -2(3)/3(x+ 1)
= 2x^2+ 2x-x-1-6/3(x + 1)
= (2x^2+x-7)/3(x+1)
= (2x^2 + x-7)/3x+ 3

No guessing
Answer:
s = 17Step-by-step explanation:
use Pythagorean theorem a² + b² = c²
where a = 8
b = 15
c = s (which is unknown)
plugin values into the formula:
a² + b² = c²
8² + 15² = s²
s = √(64 + 225)
s = √289

What is the probability of tossing two coins and having them both land on heads?
50%
33.3%
75%
25%
Answer:
25%
Step-by-step explanation:
Since there are two coins, it's 50%, and since there are two sides to choose from, that would mean 25%. There's a 25% chance either will lie on heads, tails, or both heads or both tails.
Answer:
25%
Step-by-step explanation: because one coin landing on heads is 50%, but since there are two coins you cut 50% in half

line passes through points (5, 8) and (10, 5). Line b is parallel to line a. what is the slope of line b??
Answer:
-3/5
Step-by-step explanation:
Let's go from the point (5, 8) to the point (10, 5). We can see immediately that x (the 'run') increases by 5 and y (the 'rise') decreases by 3. Thus, the slope of the line connecting these two points is m = rise/run = -3/5.
Both of these lines have the slope -3/5, given that they are parallel lines.

You are going to make cookies for a party. The recipe requires 3 cups of flour, 2 cups of chocolate chips and other ingredients. I also need to write an equivalent ratio that shows how much you need to double the original recipe, can someone help?
Answer:
Ratio of flour to chocolate = 6 : 4
= 3 : 2
Step-by-step explanation:
Original recipe
Flour = 3 cups
Chocolate = 2 cups
Ratio of flour to chocolate = 3 : 2
To double the original recipe
Flour = 3 cups × 2
Chocolate = 2 cups × 2
Flour = 6 cups
Chocolate = 4 cups
Ratio of flour to chocolate = 6 : 4
= 3 : 2

Polina the Polar Bear sat on an ice floe in the Arctic Ocean, north of Alaska. Polina was waiting for her mother, Bearnice, to return hwith some tasty seal blubber for lunch. Bearnice was hunting, waiting for seals to come up for air through holes in the ice, the same way Polar Bears have hunted in the winter for centuries. Except this year there was one big difference.
A lot more of the ice had melted last summer, and this winter it hadn’t refrozen as usual. A combination of warmer weather and changes in water and air currents was making the ocean warmer than anyone could remember, and Bearnice had to swim farther every day to find a good hunting spot.
As Polina waited for her mother to bring food back to her floe, the ice shrank bit by bit until she was sitting on very thin ice. As Polina waited helplessly, the furry white cub heard a deep voice coming from the direction of the sea.
“Hellooo little bear,” it said. Polina had never heard such a deep voice. She lifted her tired head to look out over the water, and was surprised that the voice seemed to come from a dark ice floe just offshore.
"No, wait!" It had a huge eyeball that was looking directly at her. It wasn’t an ice floe — it was the largest whale Polina had ever seen. It was also the first whale that had ever spoken to her.
“They call me Farswimmer,”said the whale, “because I travel all over the world, having adventures and learning new things. What brings you here alone, Polar Bear?” Farswimmer was very old, and he had seen many changes in his years of exploring the oceans. He certainly knew more about the world than most polar bears.
Farswimmer seemed like a nice whale, but Polina remembered Bearnice, her mother, and how she hadn’t come back from hunting.
Farswimmer blew a tall spout to distract Polina and stop her from crying.
When Polina told the whale her own story, he said, “I’m headed north anyway. You could ride on my back, and we can look for your mother. Are you ready for an adventure?” The next morning, Farswimmer and Polina charted their course and took off. Polina rode Farswimmer’s back and sometimes floated behind him, holding his tail. She also stood on his back and pretended she was surfing. It was a blast.
They took a break on an ice floe. Soon, they saw something in the distance that looked like another ice floe, but just to be sure, Farswimmer left Polina on the ice and swam to the floating object.
It wasn’t an object. It was an animal. Farswimmer used his fat nose to push the animal to Polina’s icy raft. When they got closer, Polina saw a familiar face.
“Mommy,” she yelped. Bearnice was very tired, but the sound of her cub’s voice made her happy. She opened her arms and the two embraced each other in a big bear hug.
Read the passage on the left to answer the following questions:
1)
What is the main conflict in this story?
A) Farswimmer cannot find Polina's mother.
B) Polina's mother is unable to find any seals to feed Polina.
C) Bearnice decides that she wants to let her daughter live alone.
D) The ice is melting around Polina, and her mother hasn't returned.
2)
Which statement best describes the relationship Polina the Polar Bear and the whale Farswimmer?
A) Polina is angry at Farswimmer for being so large and scary.
B) Farswimmer has no interest in helping Polina find her mother.

D) Polina is in love with Farswimmer the whale and wants to run away with her.
3)

A) as an unhappy and mean whale
B) as a kind and wise old whale

QUESTION Lin’s father is paying for a $20 meal. He has a 15%-off coupon for the meal. After the discount, a 7% sales tax is applied.
how much does lin father pay for the meal
Answer:
18.19
Step-by-step explanation:
First we must determine how much 15% of 20 is (3). Now we must subtract that from 20 (20-3=17$) Once we have that we must figure out how much 7% of 17 is ($1.19) Lastly, we must add the tax to 17.00 (17+1.19) to get 18.19.

a rectangle is 6 times as long as it is wide. the perimeter is 140 cm. find the area of the rectangle. round to the nearest tenth if necessary.
Answer: [tex]w = 10[/tex]
Step-by-step explanation:
Our perimeter will be 140 cm and our width of the rectangle will be 6w. We will then divide 14w and 140 by 14 so we can get w by itself. Then, we will divide the perimeter by the width.
Step 1: Let 6w will be our length and let the perimeter be 140 cm.
[tex]6w, P = 140 cm[/tex]
Step 2: Perimeter means that you add up all the 4 sides of the rectangle.
[tex]P = 140 = w + w + 6w + 6w = 14w[/tex]
[tex]P = 140, 14w[/tex]
Step 3: Divide both sides 14 to get the single w variable.
[tex]\frac{140}{14} = \frac{14w}{14}[/tex]
Step 4: Simplify.
[tex]10 = w[/tex]
Step 5: Flip sides.
[tex]w = 10[/tex]

(dont write random answers pls)
look at the pic attached:
Answer
the answer would be
D(5,-2).
Answer:
D(-6, 1)
Step-by-step explanation:
To determine the solution we can start by calculating the slope of AB;
A(-1, 4), B(2, -5)
m = -5 - 4 / 2 - (-1) = -9 / 3 = -3
Then CD, if to be perpendicular, should have the 'negative reciprocal' of the slope of AB. In other words it should have a slope of 1/3. We are given point C as (3, 4) so let's take each of the given options for point D, and find the slope using the two points. If the slope is 1/3rd then that is the correct option.
Now I already know the answer, so instead of going through all the options I will just check the slope with the correct answer choice. You will find the slope to be 1/3rd;
C(3, 4), D(-6, 1)
m = 1 - 4/- 6 - 3 = -3/-9 = 1/3rd
Correct, as you can see
So your solution is option c
