Answer: plane A = 333.33mph
Plane B = 500mph
Step-by-step explanation:
Given data:
Distance between the two planes = 2400miles.
Plane A flew North
Plane B flew south
Solution:
Let v represent plane A.
Let 2v represent plane B.
Distance between the two plane
v + 1.5* v = 3*v
7.5v = 2500miles
v = 333.33mph
Plane B has one and half times the speed of plane A
= 1.5 * 333.33
= 500mph
Now you see when you use a model it is harder kepause........
<span>(1.3t3 + 0.4t2 – 24t) + (8 – 18t + 0.6t2)
In adding polynomials, make sure that each term is grouped together.
1.3t</span>³ + 0.4t² - 24t
<u> + 0.6t² - 18t + 8</u>
1.3t³ + 1.0t² - 42t + 8
In a polynomial equation, arrangement of each term is dependent on the exponential number. It should be from the highest exponent to the lowest.
To solve, set up a proportion
3.25 cups x cups
---------------- = ---------------
13 servings 28 servings
Now cross multiply
13x = 28 * 3.25
Simplify.
13x = 91
Divide both sides by 13
x = 7 cups
To check your answer, use proportions again, but change the left side to 4.5 cups over 18 servings, use the same steps, if the answer is the same as above, then the answer is correct
Answer:
Option A is correct.
Step-by-step explanation:
No of Balls in Basketball = 2
No of Balls in Dodge ball = 18
No of Balls in Soccer ball = 8
No of Balls in Tennis ball = 14
Ratio of Soccer balls to Tennis balls = 4 : 7
⇒ For every 4 Soccer ball, there are 7 Tennis ball.
Ratio of Basket ball to Dodge Ball = 1 : 9
⇒ For every 1 Basket ball, there are 9 Dodge balls.
Therefore, Option A is correct.
