Answer:
305
Step-by-step explanation:
find a101of the sequence 5, 8, 11
You want the 101th term of this sequence: 5, 8, 11
a_1 = 5
a_n = (n -1)* d + a_1
a_101 = (101 - 1)*3 + 5
a_101 = 100*3 + 5
a_101 = 300 + 5 = 305
We can write that 40% of the full amount is 30 marks.
Using x for the full amount, we can say 0.4x=30.
To solve for x, we devide both sides by 0.4 (or equivalently, multiply by 2.5).
We get x = 75 marks.
Answer:
Step-by-step explanation:
To calculate the lenght of the diagonal d across the square, we can assume that the square it is compound of two right triangles. So, we can resolve this exercise using The Pythagorean Theorem.
<em>The Pythagorean theorem</em> states that in every right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the respective lengths of the legs. It is the best-known proposition among those that have their own name in mathematics.
If in a right triangle there are legs of length a and b, and the measure of the hypotenuse is c, then the following relation is fulfilled:
a is the height, b is the base, and c is
the hypotenuse.
To obtain the value of the hypotenuse
To find the value of the lenght of the diagonal d across the square, we have:
Where a = b = 20
Substituting the values
Round the answer to 2 decimal places
Answer:
7263
Step-by-step explanation:
Factor the expression:
-1/6*6(x-2y)
Divide by 6
-1(x-2y)
Then times by -1
-x+2y
Is your answer
