7 0

The answer would be:
<span>805 tens = 805 *10
805 tens = 8,050</span> <span>

That’s how you rename the number. Another example:

805 hundreds = 805*100
805 hundreds = 80,500</span> Simply multiply the given number to the name equivalent like tens, hundreds, thousands, millions, etc.

For this case we have the following definition:

tens place: number of two digits greater than zero.

We then have the following number:

805 tens

By writing the number we have:

805 tens = 805 (10)

805 tens = 8050

Rewriting the number in words we have:

8050: eight thousand fifty

Answer:

Rewriting the number 805 tens we have:

Problem 4:

Kipish [7]

Answer:

12cm and 16cm

Step-by-step explanation:

The hypotenuse of the right angle triangle = 20cm

let the other two sides be x and y;

The difference;

x = y - 4

Problem:

Find x and y;

Solution:

According to the pythagoras theorem;

x² + y² = 20² ------ i

x² + y² = 400 ----- i

and x - y = 4 ---- ii

So; x = 4 + y

Now input the value into equation (i);

(y + 4)² + y² = 400

(y+4)(y+4) + y² = 400

y² + y² + 4y + 4y + 16 = 400

2y² + 8y + 16 = 400

2y² + 8y + 16 -400 = 0

2y² + 8y - 384 = 0;

y² + 4y - 192 = 0

Factorize the equation;

y² + 16y - 12y - 192 = 0

y(y + 16) - 12(y + 16) = 0

(y-12)(y + 16) = 0

y -12 = 0 or y+ 16 = 0

y = 12 or -16

It is not realistic for the length of a body to be a negative value, so y= 12;

since;

x - y = 4,

x = 4 + 12

x = 16

Match each scenario with the type of correlation it shows

tiny-mole [99]

Answer:

1- Positive correlation

2- Negative correlation

3- No correlation

Step-by-step explanation:

1- The more a player practices free throws, the better they will be at it and therefore will make more free throws. Thus, there is a positive correlation between the time spent practicing and the number of free throws made.

2- Since each item bought has a cost, the more items are bought, lower will be the checking account balance. Thus, there is a negative correlation the number of items bought and the checking account balance.

3- There is no explicit correlation between players heights and their ability to hit a baseball therefore it is fair to assume that there is no correlation between the height of baseball player and the number of hits made
