The greatest number of cards that April can place in a row , so that the two families have same number of cards in each row is  14.

In the question ;

it is given that

number of card that Bride's family has = 154

number of cards that Groom's family has = 140 cards.

So , to find the greatest number of cards that April can place in a row we need to find the GCF(154,140) ,

to find the GCF (154,140)

prime factorization of 154 = 2*7*11

prime factorization of 140 = 2*2*5*7

common factors = 2*7

Hence the GCF(154,140) = 14

Therefore , the greatest number of cards that April can place in a row , so that the two families have same number of cards in each row is  14.

They will next meet again after 1386 seconds or 23.1 minutes from the starting point.

Given that Robert, John, and Paul begin running in the same direction from the same starting point around a circular track If they take 126 seconds, 154 seconds, and 198 seconds respectively to complete one round of the track.

The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.

To determine whether they will next meet again at the starting point.

We have to calculate the LCM of the numbers 126, 154, and 198

⇒ Prime factors of 126 = 2 × 2 × 3 ×7

⇒ Prime factors of 154 = 2 × 11 ×7

⇒ Prime factors of 198 = 2 × 3 × 3 ×11

So the LCM of the numbers 126, 154, and 198 will be as:

⇒ 2 × 3 × 3 × 7 × 11 = 1386

Therefore, they will meet after 1386 seconds or 23.1 minutes.

Ms. Walker paid $0.918*p for the computer including sales tax .

In the question ,

it is given that

discount on list price for the computer is 15%

sales tax = 8%

let the list price for the computer be $p  .

So, sales price is = p - 0.15*p = 0.85*p

tax on sale price is = 8% of 0.85*p = 0.08*0.85*p = 0.068*p

Total Price = sale price + tax on sale price

Substituting the values of tax and sale price ,

we get

total price = 0.85*p + 0.068*p

If the point M (4,3) is translated using the rules (x, y) ⇒ (x, y-2),  then the coordinates of the M' = (4,1)

The point is M(4,3)

The translation rules is

(x, y) ⇒ (x, y-2)

The translation states that the movement of the graph either horizontally  or vertically. When we translate the graph, the shape and size will not change, only the coordinates of the graph changes.

We know the values of

Answer:5760

Step-by-step explanation:

48 beats per min and its 120 min in 2 hours so multiply 120×48=5760

Given a block play problem, the minimum number of blocks Agnes can use to build a tower is 3 or 1.

To calculate the average (mean) of a set of values, first divide by the number of values in the set. Therefore, the sum of the values in the set is equal to their average multiplied by the number of values in the set. The average number of blocks in each tower was 25, and since there were 5 towers, the total number of blocks used was 5 × 25 = 125. Yuri's Tower used 32 blocks, so the remaining towers used a total of 125 minus 32 = 93 blocks.

To find the minimum possible number of blocks for Agne's tower, let the other three towers use as many blocks as possible. Now we know that Yuri's tower used the most blocks and each tower used a different number of blocks. So the other 3 towers can use up to 31, 30 and 29 blocks respectively. The result was an absolute minimum number of blocks that Agnes could use, 93 - 31 - 30 - 29 = 3

By the way, the minimum number of blocks Agnes can use is not 93 - 32 - 32 - 32 = - 3 , but negative value is not possible. so, if everyone could use the same number of blocks. Agnes must have used at least one block, as it is possible to use a negative number of blocks.

Answer:

Step-by-step explanation:

The solution to the given expression is 7,677.6.

This is a question of multiplication.

Multiplication

In mathematics, multiplication is used as a method of finding the product of two or more numbers. It is one of the arithmetic operations,  like addition, subtraction and division that we use in everyday life. The major application we can see in multiplication tables.

In arithmetic, the multiplication of two numbers is represented by  the repeated addition of one number with respect to another.

Given expression:-

[−3*914]*[(−0.1)*(−28)]

We have to find the solution of the given expression.

We have,

-3*914 = -2742

(-0.1)*(-28) = 2.8

Hence, we can write,

[−3*914]*[(−0.1)*(−28)] = (-2742)*(2.8)

(-2742)*(2.8) = 7,677.6

The powers of the imaginary number i have four possible values: 1, i, -1, and -i. Let's see some examples:

i⁰ = 1 (any number with the exponent 0 equals 1)

i¹ = i (any number with the exponent 1 is the number itself)

i² = -1 (this follows from the definition of the imaginary number, the square root of -1)

i³ = i² * i = -1 * i = -i

Now, the results start to repeat from 1 to -i:

i⁴= i² * i² = (-1) * (-1) = 1

i⁵ = i⁴ * i = 1 * i = i

i⁶ = i * i⁵ = i * i = i² = -1

i⁷ = i⁶ * i = -1 * i = -i

From that, we can follow the steps below to find the value of a power of i:

• divide the exponent by 4;

• if the rest of the division is 0, then the power equals ,i⁰ = 1,;

• if the rest of the division is 1, then the power equals ,i¹ = i,;

• if the rest of the division is 2, then the power equals ,i² = -1,;

• if the rest of the division is 3, then the power equals ,i³ = -i,.

So, for the power i⁶⁴⁹, the exponent is 649. Following the steps above, we find:

• 649/4, has a quotient of 162 and the, rest 1,. Therefore:

i⁶⁴⁹ = i¹ = i

Thus, i⁶⁴⁹ equals i.

Based on the right triangle altitude theorem, the term that completes the equation is: a. YZ.

The right triangle altitude theorem state that when an altitude is drawn to from the vertex of a right triangle to intersect the opposite side perpendicularly, the length of the altitude would be equal to the geometric mean of the line segments that are formed by the altitude on the right triangle's hypotenuse.

In other words, the square of the length of the altitude equals the product of the line segments formed, according to the right triangle altitude theorem.

XZ = altitude

WY = hypotenuse

WZ and YZ are the line segments formed.

Therefore, the equation would be:
