If a hexagon is worth 5 and a triangle is worth 3, what is a circle
Answer:
6
Step-by-step explanation:
Call pentagon p, circle c and triangle t
We have 2c + 2p = 2p + 2t + c
p = 5, t = 3 so
2c + 2(5) = 2(5) + 2(3) + c
2c + 10 = 10 + 6 + c
2c = 6 + c
c = 6
6 answer
Call pentagon p, circle c and triangle t
We have 2c + 2p = 2p + 2t + c
p = 5, t = 3 so
2c + 2(5) = 2(5) + 2(3) + c
2c + 10 = 10 + 6 + c
2c = 6 + c
c = 6

212*(2)ⁿ
6784
Step-by-step explanation:
To find the number of two tailed monkey in 2016 we have
212*2
to find in 2017
212*2*2 or 212*2^2
we can write the following equation
212*(2)^n
where n is the number of years
To find the number of monkeys in 2020 we plug in 5 for n

Select the correct operator for the following exponential expression.
2.510 ?0.420
A. >
B. <
C. =
Answer:
A: >
Step-by-step explanation:
I believe A because if you look at the 2 in the first first number or whatever its higher then the 0 in 0.420 And plus for the 5 in 2.510 its greater then the 4 so thats why i believe A because you always gotta read the question slowly and make sure which one is high or not but it can actually trick you sometimes but if they match its an equal so hope this helps ya^^
16. Hanna has a bag of 23 marbles. 5 marbles are red, 6 marbles are blue, and the rest
are pink. Abby takes out two pink marbles without replacing them. What is the
probability that the next marble he draws will be blue?
A. 10/21
B. 4/21
C. 2/7
D. 6/23
Answer:
C. 2/7
Step-by-step explanation:
When two pink marbles are taken without replacement then the total number of marbles in the bag are reduced to 21 marbles. So the blue marble, which are currently in total 6 marbles, is taken out of the total of 21 marbles. The calculation of which is done as below:
Probability of Next Marble to be blue
= Blue Marble / Total Marbles in the bag
= 6 / 21
= 2 / 7
Hence, the correct option is C. 2/7

A middle school student reads 48 books in 31/3 years. Find the students reading rate in books per year
Answer: 14 2/5 books per year
Step-by-step explanation:
From the question, we are informed that a middle school student reads 48 books in 31/3 years. The students reading rate in books per year will be calculated as:
= Total books read / Number of years
= 48 ÷ 3 1/3
= 48 ÷ 10/3
= 48 × 3/10
= 144/10
= 14 2/5 books per year

Step-by-step explanation:
If you don’t know the answer pls don’t reply thank you
Answer:
Is B
Step-by-step explanation:
It's B because you use cups with the tablespoons to find the answer. 2 is cups, and it's on the numerator, and 1.5 is cups. It would have to be a numerator since you would only use denominators to plug in the value of tablespoons in the equation. v would be the denominator with 1.5 as the numerator since we are trying to find v with 1.5, so 1.5 has to be in the same fraction.

Ed has 30 sweets. The ratio of red sweets to yellow sweets is 2:3 How
many red sweets does Ed have?
Answer:
The ratio of red sweets to yellow sweets is 12.
Step-by-step explanation:
let the number of red sweet = 2x
number of yellow sweet = 3x
according to question:
red sweets + yellow sweets = total sweet
2x +3x = 30
5x = 30
x = 30/5 = 6
red sweet = 2x = 2× 6 = 12
yellow sweet = 3x = 3× 6 = 18

(2x^5 + 3y^4) * (-4x^2 + 9y^4)
Answer:
are we supposed to solve this???
Answer:
18x^5y^4+27y^8−8x^7−12x^2y^4
Step-by-step explanation:
(2x^5+3y^4)(−4x^2+9y^4)
=(2x^5+3y^4)(−4x^2+9y^4)
=(2x^5)(−4x^2)+(2x^5)(9y^4)+(3y^4)(−4x^2)+(3y^4)(9y^4)
=−8x^7+18x^5y^4−12x^2y^4+27y^8
=18x^5y^4+27y^8−8x^7−12x^2y^4

How to expand this binomial?
Answer:
[tex] {y}^{8} + 8 {y}^{7} + 28 {y}^{6} + 56 {y}^{5} + 70 {y}^{4} + 56 {y}^{3} + 28 {y}^{2} + 8y + 1[/tex]
Answer:
Step-by-step explanation:
This is an ugly binomial expansion, which you should try to remember
These are the coefficients for the power
1,2,1 for power two
1,3,3,1 for p=3
1,4,6,4,1 for p=4
1,5,10,10,5,1 for p=5
you should see a pattern here :)
1,8,28,56,70,56,28,8,1
In general the terms are ordered for the expansion of (a+b) that has the form
a^n(b^0)+a^(n-1)b^1+...a^0(b^n) since we have (y+1)^8 we wind up with
y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1

What is 10 times something equal 24
Answer:
2.4
Step-by-step explanation:
An easy way to find this is via division.
24 ÷ 10 = 2.4 | therefore,
2.4 × 10 = 24
Answer:
2.4
Step-by-step explanation:
"something" = x
10x = 24
divide both sides by 10
10x/10 = 24/10
x = 2.4

r: 16 km. d: 32 km.
The Formula is: C = 2πr. Because it says below the rest of the data that we use 3 for pi, and since we have r, which is 16, the equation becomes C = 2(3)(16).
The answer becomes 96 Kilometers.
