Two groups of shapes. In group A, one shape has four equal side lengths of three, and no right angles. The opposite sides are parallel. Two shapes have two pairs of opposite equal side lengths. One shape has side lengths of four and eight. The other side lengths are three and two. Opposite sides are parallel, and there are no right angles. In group B there are three four sided shapes. One has opposite equal side lengths of seven and four and four right angles. One shape has four equal side lengths of three and four right angles. One shape has one set of opposite parallel sides and one right angle. None of the side lengths in the last shape are equal.
Answer: Group A :
Shape #1 : Rhombus
Shape #2 : Two parallelograms/ Two rectangles
Shape #3 : Parallelogram with opposite longer sides equal to 8, and the opposite shorter sides equal to 4.
Shape #4 : Parallelogram with opposite longer sides equal to 3, and the opposite shorter side equal to 2.
Group B :
Shape #1 : Rectangle with opposite longer sides equal to 7, and the opposite shorter sides equal to 4.
Shape #2 : Square with equal sides of 3 units.
Shape #3 : Square with equal sides of 3 units.

The mass of a basket containing 3 balls was 3.64 kilograms. The mass of the same basket and 5 balls is 5.26 kilograms. Find the mass of the empty basket in kilograms.
a. the mass of a empty basket is ___
b. explain your answer (in short)
please help
Answer:
mass of empty basket: 1.21 kg
Explanation:
the mass of basket is constant. Let the mass of basket be "b" and mass of each balls be "m"
Make equations:
b + 3(m) = 3.64 ___ equation 1b + 5(m) = 5.26 ___ equation 2solve them simultaneously,
3.64 - 3(m) = 5.26 - 5(m)-3(m) + 5(m) = 5.26 - 3.642(m) = 1.62m = 0.81 kgmass of basket,
b = 3.64 - 3(m)3.64 - 3(0.81 )1.21 kgNow
x+3y=3.64=>x=3.64-3y--(1)x+5y=5.26=>x=5.26-5ySo
3.64-3y=5.26-5y-3y+5y=5.26-3.642y=1.62y=0.81kgSo
x=3.64-3(0.81)=3.64-2.43=1.21kgElena donates some money to charity whenever she earns money as a babysitter. The table shows how much money, d, she donates for different amounts of money, m, that she earns.
d 4.44 1.80 3.12 3.60 2.16
m 37 15 26 30 18
1. What percent of her income does Elena donate to charity?
%
2. Which quantity, d or m, would be the better choice for the dependent variable in an equation describing the relationship between d and m?
3. Use your answers to write and equation that relates m and d
4.44/37= 0.12
1.80/15= 0.12
3.12/26= 0.12
3.60/30= 0.12
2.16/18= 0.12
1. She donates 12% of her income to charity
2. The quantity, d, would be the better choice for the dependent variable (y) the cost of the donation, depends on her income, if her income increases, the amount donated would increase.
3. d = 0.12m

Answer:
a. the first and last one
b. the second and third one
Step-by-step explanation:
a. 11x-3x-10x=18x, so the first one is definitely the answer. If you look at the last one, you can see that 10x+8x also equals 18x. The other options do not equal 18x, so those can be eliminated.
b. If you distribute the 3 outside of the parentheses, you can see that the expression 3(1+3y) equals 3+9y (because 3*1=3 and 3*3y=9y). So, the third one can be determined to be one of the answers. We can see that the second one also simplifies to be 3+9y, so this one can also be determined to be the answer. The other ones can be eliminated because they do not equal 3+9y.
Hope this helped! :)
Answer:
a) 18x and 8x + 10x
b) 3 × 1 + 3 × 3y and 3 + 9y
Step-by-step explanation:
11x - 3x = 8x and then 8x + 10x is left. The answers are 18x and 8x + 10x.
3 × 1 is 3 and 3y × 3 is 9y.

A school fundraiser has a minimum target of $600. Faculty donated $200 and there are 10 student clubs that are participating with different activities. Write an inequality showing the amount money each club should raise to meet the minimum target. Use f for the amount of money that each club raises.
Answer:
600=10f+200
Step-by-step explanation:
since $600 is the target, and the faculty already donated 200 dollars 200 would be the y intercept. since f is the amount of money that the clubs should raise, we can set that as 10 f since there are 10 clubs and since it needs to be inequality, it would be written in the y = mx + b format. hope this helps!

(a) Explain why her reasoning is incorrect.
(b) Rewrite the problem and solve it correctly. Clearly show your work.
Answer:
incorrect, correct answer is 4√2
Step-by-step explanation:
When you remove the square root You will have to remove them completely. so that the inside of the square root cannot be removed any more numbers (I'm not good at English but I hope u understand what I want u to know :)))
√32 = √2×2×2×2×2
Match 2 identical numbers one at a time and bring them out. ;
√32 = 2×2√2
√32 = 4√2 correct answer!
find you If you want to check if your square root removal is correct or not. Multiply the answer you have given by itself, for example:
4√2 × 4√2 = 16×√4 = 16×2 = 32 correct!

Answer:3,712÷64=58
Step-by-step explanation:
Answer: The ratio is 58:1, and the division is = 58. Scroll for solving, check, and notes.
Explanation:What we know:
The question wants us to use equivalent ratiosThe numbers 3,712 and 64 have common denominatorsAn equivalent ratio is a ratio that is something of a simplified form of large numbers, written in a fraction, with a colon, or with the word 'to'How to solve:
We need to find the equivalent ratio of 3,712 and 64, and then solve the question based on that.
Process:Finding equivalent ratios
Set up equation 3712/64
Rewrite into colon-ratio form 3712:64
Divide by common denominator /64 /64*
Solution: =58:1
*Read bottom of notes to find out how I found this denominator
Answer: The ratio is 58:1; the solution to the division is 58.Notes:
There is no way to always know the ratio's common denominator. However, there are some general rules of thumb that may help:
-All numbers have a common denominator of 1. Sometimes, that's the most simplified form.
-All even numbers (Those that end in {0, 2, 4, 6, or 8}) have a common denominator of 2
-All numbers whose digits add up to {3, 6, or 9} (such as 12: 1+2 = 3) have a common denominator of 3.
-These three numbers serve as basic building blocks. You can keep simplifying with them until you get to a prime number. Let's use our problem as an example:
3712 and 64 - both are even, simplify by 2
1856 and 32 - both are even, simplify by 2
928 and 16 - both are even, simplify by 2
464 and 8 - both are even, simplify by 2
232 and 4 - both are even, simplify by 2
116 and 2 - both are even, simplify by 2
58 and 1 - there is a prime number, so this is the simplest form.
Now we take all of our simplifications: 2^6. 2^6 = 64, so the common denominator is 64.
Check:
Our ratio, 58:1, is the simplified form of 3,712 div. 64. This is seen better by rewriting both into a fraction-ratio form:
58:1 3712 div. 64
58/1 3712/64
Luckily, our ratio has a 1 in it. This means that when we multiply the ratio by 64 (what the 1 represents), it should yield the original equation.
3712/64 = 58/1
3712/64 = (58/1)*64
3712/64 = 3712/64
Therefore, 58:1 is the correct ratio.
