Answer:
C. y=x+7
Step-by-step explanation:
If you add 7 to the values on the left, you'll get the values on the right.
Answer:
When a number is divided by 5 and the result is 247 with a remainder, one possible dividend is 1236.
The quotient of a number is the number that is gotten when a number is divided by another number. For example, the quotient of 10 and 2 is 5.
An unknown number was divided by 5 and the result was 247 with a remainder. In order to determine the number the first step is to determine the product of 247 and 5.
247 x 5 = 1235
Since the number has a remainder, the number cannot be exactly 1235. The number would lie between 1235 and 1240. The numbers can be 1236, 1237, 1238 and 1239.

Answer:
C: 70 Mins
Step-by-step explanation:
1, 20ft*15ft=300ft^2
2, 30ft*25ft=750ft^2
3, 750ft-350ft=450ft^2
4, 450 ft^2 = 30 mins
5, 350ft=750ft=1050ft^2
6, 1050/450=2.3333
7, 30*2.3333=70
8, 70 mins
<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.
