Let the full marks = x
Then, it would be: x*40/100 = 60
x = 6000/40
x = 150
Full marks will be 150
We need to write the given statement in math terms:
y increased by 4
Recall that increased means that we are adding 4 to the previous number.
Then the mathematical expression is:
y + 4
The quantity y has been increased by 4 units.
Traiangle ABE = triangle CBD this is wrote right
bc. to angle A corespond angle C
and to angle B corespond angle B
and to angle E corespond angle D
so and than you check this posted image these coresponding angles are congruent angles what mean that these two triangles are congruent
Answer:
Step-by-step explanation:
Please present these numbers as a list: 7, -21, 63, -189, ....
Otherwise it appears that you are adding them up, which is not the case.
We can tell that this is a geometric series because each new number is -3 times the previous number: -3(7) = -21, -3(-21) = 63, and so on. Let r = -3 and a = first number = 7.
a
The sum of an infinite geometric series exists if and only if |r} < 1. Here, |-3|, or 3, so in this case the sum of the series does not exist. That is, the series diverges.
