Hi there!
To add fractions there are three simple steps:
1. Make sure the bottom numbers (denominators) are the same. → In your case you're all good, both your denominators are 8.
2. Add the top numbers (numerators) and put that answer over the denominator :
-3 + 7 = 4 →
3. Simplify the fraction (if needed). → In your case, you do need to simplify your fraction :
Divide both your numerator and denominator by 4 to get your simplified fraction :
4 ÷ 4 = 1
8 ÷ 4 = 2
Your simplified fraction is :
There you go! I really hope this helped, if there's anything just let me know! :)
Okay, so lets look at the right triangle portion of the question. We can use the trigonometric ratios in order to find side a, which is opposite of the 32 degree angle.
We have three options, SOH CAH and TOA.
We will use SOH, or sine opposite over hypotenuse because we are trying to find the opposite side and we have the hypotenuse length.
So we set it up as Sin(32) = X/17. Multiple both sides by 17 to solve for X
You end up with X = 9 cm (when rounded)
Meaning that the measure of side a is about 9 cm
Answer: Let x = number of pounds of jelly beans
y = number of pounds of almonds.
Then, 4x + 8y = 33
2x + 3y = 13
Multiply the second equation by -2 to get the system:
4x + 8y = 33
-4x - 6y = -26
Adding the equations, we get 2y = 7. So, y = 3.5
Substitute for y in either of the given equations: 2x + 3(3.5) = 13
2x + 10.5 = 13
2x = 2.5
x = 1.25
ANSWER: a pound of jelly beans costs $1.25 and a pound of almonds costs $3.50.
Step-by-step explanation:
The <em><u>correct answers</u></em> are:
90°, 180° and 270°
Explanation:
Squares have rotational symmetry at 90°. This can be found by dividing the number of degrees in a circle, 360, by the number of sides, 4:
360/4 = 90
This means that at all multiples of 90, the square will rotate onto itself. This means that 90, 180 and 270 are all correct.
