8 1/2 - 7 2/3 (Turn them into improper fractions)
   17/2-  23/3  ( Find the Least Common Denominator: 6) since 2*3= 6 you have to multiply 3 times 17 so that gives you 51/6, then since 3*2= 6 you have to multiply 23 times 2 which gives you 46/6

Then you subtract them: 51/6 - 46/6= 5/6, you keep the denominator the same and just subtract the numerator

Given that sin0=21/29 what is the value cos 0 for 0°&lt; 0&lt;90°
sp2606 [1]

Answer:

20/29

Step-by-step explanation:

sin θ = 21/29

Use Pythagorean identity:

sin² θ + cos² θ = 1

(21/29)² + cos² θ = 1

441/841 + cos² θ = 1

cos² θ = 400/841

cos θ = ±20/29

Since 0° < θ < 90°, cos θ > 0.  So cos θ = 20/29.

Aliyah $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?
MaRussiya [10]
Each pencil cost $2.

Explanation: She had $24 before buying the pencils and after she had $10. 24-10=14 so the total she spent on pencils was $14. She bought 7 pencils so you divide 14 by 7 (14/7=2) which equals 2. So each pencil cost $2.
