NUMBER 3 :
150 feet / 15 = 10 units
120 feet / 15 = 8 units
So it will be 10 units by 8 units
NUMBER 4:
A) 525/4.2 = 120
The scale used was 120
B) 0.6 inches = 0.0152
525 / 0.0152 = 35 sheets tall
Answer:
first is 3.5, second is 1
Step-by-step explanation:
-4.5 = x + 2x - 6
-4.5 - 6 = 3x
10.5 = 3x
10.5/3 = x
3.5 = x
2(3.5) - 6
7 - 6
1
Answer:
T represents the amount of time it will take him to travel 200 meters if he swims at 45 meters per minute.
Step-by-step explanation:
To answer this, we substitute 12 ft to the f(h) in the given equation,
f(h) = -8t² + 8t + 12 = 12
Subtracting 12 from both sides of the equation will give us an answer of,
-8t² + 8t = 0
Then, we transpose 8 to the other side and divide the equation by -8 and t, we get an answer of t = 1 second.

Answer: Choice D) 3n^2</h3>
"mono" means "one". I often think of "monorail" which means "one rail" to help remember this. So "monomial" means "one term". This reduces our choices to either C or D, as they show one term each. Choices A and B are ruled out as these are binomials, showing two terms each.
Choice C shows a cubic monomial since the exponent here is 3. So the degree is 3. We can rule out choice C.
Choice D has a 2nd degree monomial because the exponent is 2. The leading coefficient is 3 as this is the number to the left of the variable term. All of choice D fits with the description of "A monomial of the 2nd degree with leading coefficient of 3"
