Take the unknown number as 'y'.
=》33% = 33/100
=》1.45 = 145/100
33/100 × y = 1.45
33/100 × y = 145/100
33y = 145/100 × 100/1
33y = 145
y = 145/33
y = 4.39

Answer:
A, C, D
Step-by-step explanation:
1) A triangular pyramid has the same number of faces as vertices: 5
2) C - The sum is 5 + 6 =11
3) D - Euler's Formula tells us that if we add the number of faces and vertices together and then subtract the number of edges, we will get 2 as our answer.
Answer:
d = 7
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Give a₁₀ = 67 and a₁ = 4 , then
a₁ + 9d = 67
4 + 9d = 67 ( subtract 4 from both sides )
9d = 63 ( divide both sides by 9 )
d = 7
Solutions are 3 and - 5.
Step-by-step explanation:
Step 1:
Given equation is 3x² + 6x = 45. Factorize the equation to get the solutions.
⇒ 3x² + 6x - 45 = 0
⇒ x² + 2x - 15 = 0
⇒ x² + 5x - 3x - 15 = 0 (Product and Sum Method where product of coefficients = - 15 and sum = 2)
⇒ x (x + 5) - 3(x + 5) = 0
⇒ (x - 3)(x + 5) = 0
⇒ x = 3, - 5
Hi there!
To find the answer, you divide one of the numbers by 3, and some others by -3.
I can show you how to do so! :D
243 ÷ -3 = -81
-81 ÷ 3 = 27
27 ÷ 3 = 9
Next three terms -
9 ÷ 3 = 3
3 ÷ 3 = 1
1 ÷ 3 = 0.3333, the 3 is repeating over and over again
I think this is the answer, based off my notes :)
That's your pattern!
Hope this helps!
Message me if you need anything else, I'd be happy to answer any other questions! :D
