Complete Question
The coach recorded how fast his runners ran 1 mile. Emmett ran a mile in 9.73 minutes, Kate ran a mile in 10.87 minutes, and Rubin ran a mile in 8.46 minutes. How many more minutes did Emmett run than Robin?
a. 1.37 minutes
b. 1.27 minutes
c. 2.27 minutes
d. 1.27 seconds
Answer:
1.27 minutes
Step-by-step explanation:
Emmett ran a mile in 9.73 minutes
Kate ran a mile in 10.87 minutes
Rubin ran a mile in 8.46 minutes.
How many more minutes did Emmett run than Robin?
This is calculated as:
Number of minutes Emmett ran - Number of minutes Rubin ran
= 9.73 minute - 8.46 minutes
= 1.27 minutes
Option b is correct
Answer:
15 feet
Step-by-step explanation:
The question talks about;
- A rectangular flower bed whose dimensions are 12 ft by 9 ft
We are required to determine the length of the diagonal
To answer the question, we need to know the following;
- All the angles in a rectangle are right angles
- A diagonal divides a rectangle into two right-angled triangles
- The dimensions of the rectangle acts as the legs of right angled triangle.
Therefore;
Using Pythagoras theorem;
a² + b² = c²
Where, c is the hypotenuse (in this case the diagonal)
a and b are the shorter sides of the right-angled triangle
Therefore;
c² = 12² + 9²
c² = 144 + 81
= 225
c = √225
= 15
Therefore, the length of the diagonal is 15 feet
ANSWER : D
EXPLANATION : 81 > 13 is true
Answer:
b) Use the distributive property to get 4c-12=8
c) Divide both sides by 4 to get c-3=2
Step-by-step explanation:
Solve the equation 4(c-3)=8
What are two ways to start solving this equation?
We are given the Equation
4(c - 3) = 8
The two ways to start solving this Equation is given as:
1. 4(c - 3) = 8
We expand the brackets, using Distributive property
4c - 12 = 8
Or
2. 4(c - 3) = 8
Divide both sides by 4
4(c - 3)/4 = 8/4
c - 3 = 2
Therefore, options b and c is correct
7. C. y = 2x - 3
8. Both are correct
Step-by-step explanation:
7. Multiply the x value by 2, then subtract three. You eill notice they all equal to the corresponding y value
8. Divide each value by 2, (the same as multiplying by one half ) then subtract 2 from the quotient. you will get the corresponding y value for both tables.
