<h2>Question 9:</h2>
1. Use Pythagorean Theorem (a²+b²=c²) to solve for missing side of triangle and rectangle. x²+16²=20², or x²+256=400. So, x²=144, and x=12
2. Use formula: 1/2(h)(b1+b2). 1/2 (12) (30+14).
3. Simplify: 1/2 (12) (44)=1/2(528)=264
Area of whole figure is 264 square mm.
<h2>Question 10:</h2>
Literally same thing but with trigonometry.
1. Use sine to find out length of dotted line: sin(60°)=x/12
2: Simplify: 12*sin(60°)=x. x≈10.4 (rounded to the nearest tenth)
3. Use Pythagorean Theorem to find out last leg of triangle: 10.4²+x²=12²
4: Simplify: 108.16 +x²=144. x²=35.84 ≈ 6
5: Use formula: 1/2(h)(b1+b2). 1/2 (10.4) (30+36)
6: Simplify: 1/2 (10.4) (66) =343.2
7: Area of figure is about 343.2
Remember, this is an approximate answer with rounding, so it might not be what your teacher wants. The best thing to do is do it yourself again.
Answer:
i think its A but not %100
Step-by-step explanation:
Answer:
he has 0.66 of fabrics remaining, 0.66 can be 33/50
Step-by-step explanation:
Answer:
so to find slope for ordered pairs do y-y over x-x make sure the ordered pairs match up vertically
Compare Values of 5's:
552, 299 ======> 5, 52,, 299
<u>5 ===> Millions Place</u>
<u>5 ===> Hundred-Thousands</u>
2 ===> Ten-Thousands Place
,
2 =====> Thousands Place
9 ===> Hundreds Place
9 ===> Tens Place
Hope that helps!!! : )
