Answer:
B. 4200
Step-by-step explanation:
A suitable calculator can add the terms for you. (See attached)
__
The first term is 69, and the common difference is 75-69 = 6. The general term is ...
an = a1 +d(n -1)
an = 69 +6(n -1)
Then the 28th term is ...
a28 = 69 +6(27) = 231
The average term is (a28 +a1)/2 = (231 +69)/2 = 150.
The sum is the number of terms multiplied by the average term:
sum = 28×150= 4200
Let x and y be the numbers;
We have x + 2y = 9 and 2x + y = 21;
Then, x = 9 - 2y;
Finally, 2(9-2y) + y = 21 ;
18 - 4y + y = 21;
18 - 3y = 21;
-3y = 3;
y = - 1;
x = 9 - 2× (-1);
x = 9 + 2 ;
x = 11;
Answer:
B) 6, 8, 10
Step-by-step explanation:
All right triangles will follow the following theorem (Pythagorean theorem):
, where
and
are two legs of the triangle and
is the hypotenuse. Out of all answer choices, only B) 6, 8, 10 follow this theorem.
Step-by-step explanation:
It is given that Joe paid 14.00 for a board game this is 70% of the original price what is the original price.
Let the original price of board game be
X.
x * 70/100 = 14
x * 7/10 = 14
Multiply both sides by 10.
7x = 140
Divide both sides by 7.
x = 20
See there is no pink
So probability of selecting a pink is 0 .
The probability of orange is 20% or 0.2
The probability of purple is 30% or 0.3
As there is no color mentioned for rest part at max probability of pink is 0.5 .
- But by now it's 0 as it's not mentioned
