Answer:
4√10
Step-by-step explanation:
Hello!
Let's first simplify the radical.
We can do this by expanding the radical:
We need to pull out a perfect square factor to expand a radical and simplify it. In 45, we have 9 and 5 multiplied, and 9 is a perfect square.
Let's work with √45:
√45 can be written as √9 * √5 (using the rule √ab = √a * √b)√9 simplifies to 3, so it is 3√5Now we can simplify the operation in the parenthesis by combining like terms:
3√5 + √5√5 + √5 + √5 + √54√5Now using the same rule as above, we can multiply the values:
√2(4√5)4√10Your solution is 4√10

heresa earned scores of 88 points, 84 points, 88 points, and 91 points on four tests. What is the lowest score she can get on the fifth test and still finish with an average score of 90 points?
96 points
97 points
98 points
99 points
Answers
Answer:
99 points
Step-by-step explanation:
total of scores of 4 tests = 88 + 84 + 88 + 91 = 351
5 tests with an average score of 90:
⇒ total of scores = 5 × 90 = 450
Lowest score of 5th test = 450 - 351 = 99 points
Answer:
99 points
points scored:
88 points , 84 points, 88 points , 91 points, let the fifth test points be "n"
given score with an average 90 points[tex]\sf \rightarrow \dfrac{88 +84+88+91+n}{5} =90[/tex]
[tex]\sf \rightarrow 351+n =90 (5)[/tex]
[tex]\sf \rightarrow n =450-351[/tex]
[tex]\rightarrow \sf n = 99[/tex]

How do you convert 3 1/3 yards to inches? Use the drop-down menus to explain your answer.
Answers
Since, there are 36 inches in 1 yard, multiply 3 1/3 by 36
So, 3 1/3 yards = 120 inches
Answer:
120 inches
Step-by-step explanation:
To convert 3 1/3 yards to inches, you first need to figure out how many inches are in one yard. 1 yard=36 inches.
After this, you would turn your mixed fraction into an improper fraction and then multiply by 36 inches. It would look like this:
10/3 * 36/1
Here, you would cancel out the common factors by factoring 36 by 3.
12*3=36 ----> 10/3 * [tex]\frac{3(12)}{1}[/tex] ----->
Lastly, multiply 10 by 12 and your answer would be 120 inches.

Answers
Answer:
22/21
Step-by-step explanation:
1/3 + 5/7
LCM of 3,7 = 3 x 7 = 21
1/3
= 1/3 x 7/7
= ( 1 x 7 )/( 3 x 7 )
= 7/21
5/7
= 5/7 x 3/3
= ( 5 x 3 )/( 7 x 3 )
= 15/21
1/3 + 5/7
= 7/21 + 15/21
