Answer:

\therefore10m+\frac{n^2}4 =54

Step-by-step explanation:

Variables : The value of a quantity which can be changed.

Monomial : Monomial contains only one term.

Example 3x, 4,6y² etc.

Binomial: Binomial contains two terms.

Example 3+4y, 20+7z etc

Trinomial: Trinomial contains 3 terms.

Example 5x-2y+5, 7z-3y+4x etc.

Given that,

10m+\frac{n^2}4  [ It is a binomial.]

Putting m =5 and n=4

= (10\times 5)+\frac{4^2}4

=50+\frac{4\times4}{4}

=50+4

=54

\therefore10m+\frac{n^2}4 =54

aleksandr82 [10.1K]

Answer:

He will receive $515 for the 17 coins

Step-by-step explanation:

In this question, we are asked to calculate how much will be received for 17 coins , with each coin having a specific value in the US currency.

Obviously, there are four coins, so let’s proceed to get the amount he gets per type of coins.

For the m coin, she has 3 pieces. One m coin has a value of $10, then the amount of coins she makes on the m coins will be 3 * 10 = $30

For the a coin, he has 7 pieces. One m coin has a value of $5, then the amount of coins she makes on the a coins will be 7 * 5 = $35

For the t coin, he has 5 pieces. One t coin has a value of $50, then the amount of coins she makes on the t coins will be 5 * 50= $250

For the h coin, she has 2 pieces. One h coin has a value of $100, then the amount of coins she makes on the h coins will be 2* 100 = $200

The total amount made on the 17 coins would thus be mathematically equal to;

Amount made on m coins + Amount made on a coins + Amount made on t coins + Amount made on h coins

The total amount = $30 + $35 + $250 + $200 = $515

Using vector concepts, it is found that:

The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.

<h3>How can a vector be represented in component notation?</h3>

Given a magnitude M and angle \theta, then a vector V can be represented as follows in component notation:

V = (M\cos{\theta}, M\sin{\theta})

In this problem, the magnitude and the angle are given, respectively, by:

M = 12, \theta = 143^\circ

Hence:

V = [12cos(143º), 12sin(143º)] = (-9.58, 7,22).

Which means a displacement of 9.58 miles to the west(negative x = west) and 7.22 miles to the north(positive y = north).

The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.

trapecia [35]

Answer:

There are 5 cats and 6 children

Step-by-step explanation:

Let x = number of cats

Let y= number of children

Counting heads gives 11

X+Y = 11 .....eq1

Counting feet gives 32

Cats has 4legs,child has 2 legs

4X + 2Y=32 ....eq2

X = 11 - Y

Put in eq2

4(11-Y) + 2Y = 32

44 - 4Y + 2Y=32

12=2Y

Y=12/2=6

Y=6= Children

Put Y=6 in eq2

X + 6=11

X=11-6=5

X= 5 = cats
