Answer:

Step-by-step explanation:

The record jump in the pole vault was 6 meters. The new record set by the athlete is 8 meters. The difference between the two records(old and new) would be new record - old record. It becomes

8 - 6 = 2 meters

Therefore, the percentage of the old record that is the difference between

the two records would be

Difference/old record × 100

It becomes

2/6 × 100 = 33.33% rounded up to 2 decimal places

Answer:

33.33%

Step-by-step explanation:

From the given question, given that;

Old record = 6 meters

New record = 8 meters

The difference between the two records = New record - Old record

                                                                    = 8 - 6

                                                                    = 2 meters

The percentage of old record that is the difference between the two records = \frac{Difference between the two records}{old record} × 100%

                                     = \frac{2}{6} × 100%

                                    = 33.3333%

The percentage of old record that is the difference between the two records is 33.33%.

Please help this is so difficult
White raven [17]

Answer:

B

Step-by-step explanation:

For a line to be parallel it must have the same slope

6x-2y=-5

+5        +5

6x-2y+5 = 0

   +2y       +2y

6x+5  =2y

/2        /2

3x+5/2=y                  So the slope is 3 and we know it can only be either B or D

Now we need to find which line passes through (7,-2) and we find this by plugging 7 into B and D

B. -2= 21-23 TRUE

D. -2 = 21+ 23 FALSE

So the answer is B

Raul is practicing for baseball tryouts he wants to find how far he can hit a baseball he hits the ball 10 times and measures th
wel

Answer:

See Explanation

Step-by-step explanation:

Given

n = 10 --- Number of tryouts

Required

Determine the average distance

<em>This question has missing details, as the distance he hits the ball in each tryout is not given. However, I'll give a general explanation.</em>

<em></em>

The mean is calculated as:

\bar x = \frac{\sum x}{n}

\sum x means the sum of the distance in each tryout.

Assume that the distance in the 10 tryouts are: 6, 8, 5, 9, 4, 5, 8, 7, 7, 6.

So, the mean is:

\bar x = \frac{6+ 8+ 5+ 9+ 4+ 5+ 8+ 7+ 7+ 6}{10}

\bar x = \frac{65}{10}

\bar x = 6.5}

<em>So, the average distance is 6.5</em>

What is the length (magnitude) of the vector (5 -2) <br> a. √29<br> b. 5√5<br> c. 5<br> d.√2
malfutka [58]

Answer:

a. √29

Step-by-step explanation:

The formula for the magnitude of a vector is magnitude = sqrt(x^2 + y^2).

For vector (5, -2):

magnitude = sqrt(5^2 + -2^2)

magnitude = sqrt(25 + 4)

magnitude = sqrt(29)

Therefore, the answer is √29.

Hope this helped :D

Erica makes necklaces from beads. Each necklace consists of blue, white and green beads in the ratio of 6 : 4: 1 One necklace ne
Assoli18 [71]

Answer:

<u>For one Necklace you would need...</u>

24 blue beads.

16 white beads.

4 green beads.

Ratio: 24: 16: 4

Step-by-step explanation:

If you quadruple the amount of beads from the original amount (6 : 4: 1), the total beads for that necklace will be 44.

Step 1: 6 x 4 = 24 (amount of blue beads in necklace).

Step 2: 4 x 4 = 16 (amount of white beads in necklace).

Step 3: 1 x 4 = 4 (amount of green beads in necklace).

Now check to see if the total of all types of beads sum up to 44:

Step 4: 24 + 16 + 4 = 44

______________-

There is your answer:

You need 24 blue beads, 16 white beads, and 4 green beads to have a total sum of 44 beads in that one necklace.
