In complete sentences explain why you can sometimes add square roots with different radicands. Give an example where you can add square roots with different radicands and an example where you cannot add square roots with different radicands.

Answers

Answer:

Just as with "regular" numbers, square roots can be added together. But you might not be able to simplify the addition all the way down to one number. Just as "you can't add apples and oranges", so also you cannot combine "unlike" radical terms. In order to be able to combine radical terms together,

those terms have to have the same radical part.

A gallon of gold weighs 160.7 pounds, while a gallon of silver weighs 87.6 pounds. How many pounds would 6.2 containers weigh if each container held a gallon of gold and a gallon of silver?
A.1,573.66 pounds
B.1,743.22pounds
C.14,620.22 pounds
D.1,539.46pounds

Answers

Answer:

The answer is D.

Step-by-step explanation:

First, you would multiply 160.7x6.2. The answer would be 996.34. Next, you would also multiply 87.6x6.2. This is equal to 543.12. You would then add these two products together and get a total of 1539.46 pounds.

If granola costs $2.20 per pound, how much does 0.8 pound of granola cost?

$1.40
$1.76
$2.28
$2.75

Answers

Answer:

$1.76

Step-by-step explanation:

when you multiply 2.20x 0.8 you get 1.76. at first I thought division was needed, but the answer to 2.20/0.8 is 2.75- which is more than the original cost. (sorry if this is confusing but) 0.8 pound is less than 1 pound, so the answer would need to be less than 2.20.

The correct answer is 1.76

In the diagram, which two angles must be supplementary with angle 6?

NEED ANSWER ASAP
4 lines intersect to form 16 angles. The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16; 9, 10, 11, 12.
Angle 5 and Angle 7
Angle 1 and Angle 10
Angle 14 and Angle 16
Angle 7 and Angle 11

Answers

i believe it’s 5 and 7

The two angles must be supplementary with angles 6 will be angle 5 and 7.

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

⇒ 4 lines intersect to form 16 angles.

And, The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16,

Here, two combinations of angles 5 and 7 are having a sum of 180 degrees with angle 6.

So, The supplementary angles to angle 6 are angle 5 and angle 7.

Thus, The two angles must be supplementary with angles 6 will be angle 5 and 7.

The first part you would add the -1/16 with -11/16 to get an answer of -12/16. Fill in the first blank from the left to be 11 so it is 11/16. The other blank in that row should be a 1 like it is in the original equation.
Second row blank would become 12 because 11+1 =12. The third row of blanks would then simplify 12/16 to be 3/4 because both 12 and 16 can be divided by 4 to make 3 and 4 respectively.
-3/4 + -1/4 equals -1 because -4/4 simplifies to -1.
