Yes, the set of people who wear expensive perfume is well-defined. A set is said to be well-defined if its definition assigns it a unique value. Otherwise, the set is said to be not well-defined or ambiguous."Well-defined” means that any given object in the entire world, whether abstract or concrete is either an element of the set or isn't.

74,443 the value of the digit 4 in the hundreds place is 10 time the value of the 4 in what place value?

Inessa [10]

ANSWER: 4 in the TENS place value.
EXPLANATION:
Okay so 74,443
It is asking if the digit 4 in the hundreds which is 400 is 10 times as large as what other 4 digit
Now the other 2 fours in this number are one in the thousands and one in the tens (4000 and 40)
If you multiply 4000 by 10 that is MUCH larger than 400
If you multiply 40 by 10 you would equal 400
Therefore the answer is the 4 in the TENS place value.

Suppose j varies jointly with g and v, j=1 when g=6 and v=3. Find j when g=8 and v=11

Lady bird [3.3K]

j=4.88 when g=8 and v=11

Further explanation:

When the increase/decrease in one quantity cause increase/decrease in other quantity, it is called direct variation.

Variation is always accompanied by a variation constant.

Given

g and v vary directly with j

IT can be written as:

j∝gv

Putting the variation constant k

j = kgv

Putting g = 6 and v=3

$j = kgv\\1 = k * 6 * 3\\1 = 18k\\k = \frac{1}{18}$

So the value of k is 1/18 which makes the equation

$j = \frac{1}{18}gv\\ Putting\ g=8\ and\ v=11\\j = \frac{1}{18} * 8 * 11\\j = \frac{88}{18}\\ j =4.88$

So, j=4.88 when g=8 and v=11

I need help with this can you show me how to work it out pls

JulsSmile [24]

Answer:

Answer is in the pic

Step-by-step explanation:

A translation is just a movement of the figure so in this case you just add 3 to the x part of the coordinate.

so originally k (-2,5) m (-3,1) l (1,1)

add 3 to x so

k (1,5) m (0,1) l (4,1)
