The unit rate of the copy machine expressed in terms of copies per second is found by calculating the ratio 45 copies/25 seconds, which equals 1.8 copies/second.
To find the unit rate of copies per second, we need to divide the total number of copies by the total time taken. In other words, we have to find out how many copies are made in one second. Here, the copy machine makes 45 copies in 25 seconds.
To calculate the unit rate, we use the formula Unit Rate = Total Quantity / Total Time. Substituting the given numbers into the formula, we get:
Unit Rate = 45 copies / 25 seconds = 1.8 copies/second.
This means the copier's unit rate is 1.8 copies per second.

1.8
Step-by-step explanation:
45 divided by 25
The total number of cards including each pack after giving 3 cards from each pack will be 56.
Arithmeticoperators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Division = divide any two numbers or variables called division.
Multiplication = to multiply any two or more numbers or variables called multiplication.
As per the given,
Total number of packs = 8
Number of cards in each pack is 10 so total cards = 8 x 10 = 80 cards.
He gave 3 cards in each so 8 x 3 = 24 cards.
Remainingcards = 80 - 24 = 56 cards
Hence "The total number of cards including each pack after giving 3 cards from each pack will be 56".

Answer:
Jerome has 50 baseball cards left.
Step-by-step explanation:
Jerome had 8*10 = 80 baseball cards total. He then gave his sister three from each of the ten packs (3*10 = 30).
Therefore, Jerome has 80 - 30 = 50 baseball cards.

The required point that is common for all lines of symmetry for a given circle is the center of the circle.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.
Here,
For the given circle, Each and every line of symmetry in the circle is termed to be diameter and each diameter of the circle passes through the center.
Thus, the required point that is common for all lines of symmetry for a given circle is the center of the circle.

hello :
the n-ieme term is : An=A1×r^(n-1)
A1 the first term r : the common ratio
in this exercice : A1 =15 r = 1/3 n = 4
A4=15×(1/3)^(4) =15×4^4 =3840
