Jeff can type 110 words in 2 3/4 minutes. How many words can he type
in 4 1/4 minutes? *

Answers

Answer 1

Answer:

680

Step-by-step explanation:

What we should know is how many words he can type in 1/4 minutes. We can do 110 divided by 2.75 which is 40. 40 is the number of words he can type in 1/4 minutes. Now multiply this 17 (4 1/4 = 17/4) and you get 680. I believe he can type 680 words in 4 1/2 minutes. (Make sure my answer is correct)

Answer:

Step-by-step explanation:

answer no 3:

1] Factor out the common term 2.

2(3x+y) = -26

2] Divide both sides by 2.

3x+y= -26/2

3x+y = − 13

 

3]Subtract y from both sides.

3x = - 13-y

4] Divide both sides by 3.

x = -13-y/3

Part 2:-

Add 6y to both sides.

x=21+6y

x=21+6y

x=3/2+1/2√21 or x=3/2+-1/2√21

Step-by-step explanation:

For this equation: a=1, b=-3, c=-3

1x2+−3x+−3=0

Step 1: Use quadratic formula with a=1, b=-3, c=-3.

x=−b±√b^2−4ac/2a

x=−(−3)±√(−3)^2−4(1)(−3)/2(1)

x=3±√21/2

x=3/2+1/2√21 or x=3/2+−1/2√21

Answer:

3: x= 3.7912874, x= 0.79128784

4: x= 0.62181997, x= -4.28848664

B.) √21 units
C.) 29 units
D.) 7 units
WILL MARK BRAINLIEST!!!!

Answers

Answer: The correct answer is 29 units

Step-by-step explanation: Can i Get the brainliest answer?

The distance between points (8, 3) and (3, 1) on the coordinate plane is √29 units.

Given that, the distance between points (8, 3) and (3, 1) on the coordinate plane.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

Now,

Put, (x1, y1)=(8,3) and (x2, y2)=(3,1) in distance formula, that is

Distance = √[(1-3)²+(3-8)²]

= √(4+25)

= √29 units

Therefore, the distance between points (8, 3) and (3, 1) on the coordinate plane is √29 units.
