Answer:
AB ≈ 4.41
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos25° =
=
=
( multiply both sides by AB )
AB × cos25° = 4 ( divide both sides by cos25° )
AB =
≈ 4.41 ( to the nearest hundredth )
Answer:
9.5
Step-by-step explanation:
The legs of the triangle are
3 and 9
From the Pythagorean Theorem
c² = a²+ b²
c² = 3² + 9²
c² = = 9 + 81
c² = 90
Take the square root of both sides
c = 9.4868329805
Rounded
9.5
We have been given that the label on a can of lemonade gives the volume as 12 fl oz or 355 ml and we are asked to verify that these two measurements are nearly equivalent.
Since we know that 1 fluid ounce equals 29.5735 ml. Let us find volume of lemonade can in ml by multiplying 12 by 29.5735.



We can see that 354.882 is nearly equivalent to 355. Therefore, we can say that these two measurements are nearly equivalent.
Given:
Markers are sold in packages of 12 and pens are sold in packages of 8.
To find:
Least amount of markers and pens Rick needs to buy to have an equal number of markers and pens
Solution:
To find the least amount of markers and pens, we need to find the LCM of 12 and 8.
Prime factors of 8 and 12 are


To find the LCM, multiply all factors but the common factors are included only once.


Therefore, the least amount of markers and pens Rick needs to buy to have an equal number of markers and pens is 24.
Answer:
The answer is B
Step-by-step explanation:
If u use calculator,u will get the ans as x¹=6 and x²= -2 but u have to change it to the opposite which means negatif to positive(-2=2) and positive to negative(6= -6).Hope u can understand...sorry,English isn't my first language
