Answer:

60 square meters

Step-by-step explanation:

The area of a triangle is with the formula A = 1/2 b*h. The base and height are the measurements of the sides of a triangle which form a 90 degree angle. When all three measurements are given, the base and height are the smallest since the largest is the hypotenuse. Here b = 8 and h = 15.

So the area is A = 1/2 * 8 * 15 = 60.

Answer:

B

Step-by-step explanation:

If p and q are both true, then p→q is true.

If p is true, q is false, then p→q is false.

If p is false, q is true, then p→q is true.

If p and q are both false, then p→q is true.

So if you know that p→q and p are both true, then q must be true (because if q is false, then p→q must be false).  

Answer:

B. 3/5

Step-by-step explanation

1/5 of icing = 1/3 of a cake

1/3 * 3/1 = 3/3 = 1 (a whole cake)

1/5 * 3/1 = 3/5

The answer to your question is B, 3/5.

Answer:

50 nickels, 20 quarters.

Step-by-step explanation:

System of equations (q = # of quarters, n = # of nickels):

q + n = 70, 0.25q + 0.05n = 7.50

the first equation can be changed to q = 70 - n, so we are able to substitute q with 70 - n.

So, it will look like 0.25*70 - 0.25n + 0.05n = 7.50. This can be simplified to 0.2n = 10, which means that n = 50.

Knowing that we can solve q + 50 = 70, which means that q = 20.

By applying algebraic principles, it's determined that Kevin and Randy Muise have 20 quarters and 50 nickels. We've used two equations to solve this two-variable problem. The first equation comes from the total number of coins, and the second comes from the total value of the coins

The subject of this question is a classic two-variable algebra problem. We have two unknowns here: the number of quarters (which we'll call Q) and the number of nickels (which we'll call N).

From the given information in the question, we can create the following equations:

Essentially, the first equation states that the total number of coins is 70, and the second equation is representative of the total value in dollars of the coins.

From the first equation, we can isolate one variable: N = 70 - Q.

Substituting this value into the second equation gives us

0.25Q + 0.05(70 - Q) = 7.50

⇒0.20Q +3.50 =7.50

⇒0.20Q= 4

⇒Q= 20

Solving this equation gives us the value of Q (number of quarters) = 20.

Substituting Q = 20 into our first equation: 20 + N = 70, we can find the value of N (number of nickels) = 50.

So, Kevin and Randy Muise have 20 quarters and 50 nickels.

Answer: OPTION D

Step-by-step explanation:

THe quadratic formula is shown below:

[tex]x=\frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]

Given the quadratic equation shown in the image, you have that:

a=1

b=3

c=4

Therefore, when you susbtityte these values into the formula you obtain the following solution:

[tex]x=\frac{-3\±\sqrt{3^2-4(1)(4)}}{2*1}[/tex]

[tex]x=\frac{-3\±\sqrt{-7}}{2}[/tex]

Answer:

D.x = (-3±√-7) / 2

Step-by-step explanation:

We have given  a quadratic equation.

x²+3x+4  = 0

From above equation, a = 1, b = 3 and c = 4

We have to find the solution of given equation bu using quadratic formula.

x  = (-b±√b²-4ac) / 2a

Putting given values in above formula, we have

x = (-3±√(3)²-4(1)(4) ) / 2(1)

x = (-3±√9-16) / 2

x = (-3±√-7) / 2 which is the answer.

If the dices have equal probability, that means each number has a 1/6 chance of getting picked because there are 6 sides to a dice with 6 different numbers.

There are a total of 36 combinations, because 6 * 6 is 36.

It would be impossible to have a sum of 1, as the lowest number on both dice is 1. 1 + 1 = 2. Therefore there is a 0/36 probability of getting a sum of 1.

Step-by-step explanation:

The cost at which both video rental plans are the same is $48, which occurs when a customer borrows 20 DVDs in a month.

The student asked about the cost at which both video rental plans offered by a company would be equal in value. To find this, we need to establish an equation for each plan and set them equal to each other. The first plan includes a membership fee of $8 and charges $2 for every DVD borrowed, which can be represented as cost = $2 × number of DVDs + $8. The second plan is a flat rate of $48 per month for unlimited rentals.

Now we set the equations equal to each other: $2 × number of DVDs + $8 = $48. Solving for the number of DVDs would look like this:

Therefore, the break-even point where both plans cost the same amount is at 20 DVDs borrowed. At this point, the customer would pay $48 with either plan.

Answer:

The correct option is 4.

Step-by-step explanation:

The given function is

[tex]f(x)=5(2)^x[/tex]

Put x=0,

[tex]f(0)=5(2)^0=5\times 1=5[/tex]

Put x=1,

[tex]f(1)=5(2)^1=5\times 2=10[/tex]

Put x=2,

[tex]f(2)=5(2)^2=5\times 4=20[/tex]

Put x=3,

[tex]f(3)=5(2)^3=5\times 8=40[/tex]

Only table 4 represents the correct value of the given function, therefore the correct option is 4.

The table representation of the exponential function f(x)=5*2^x is: for x=0, f(x)=5; for x=1, f(x)=10; for x=2, f(x)=20; for x=3, f(x)=40.

To find the table representation of the exponential function f(x)=5*2^x, we need to calculate the values of f(x) for different values of x. Remember, any number raised to the power of 2 is being squared, but in this case, x can be any integer, and we're multiplying the result of 2 raised to that power by 5. Here's how you calculate the first few values:

Therefore, the correct table representation of the function f(x)=5*2^x is:

Answer:

24 x + 10 y >= 200

Step-by-step explanation:

as x represents centerpiece and y represent  bouquet and total number of roses should be atleast 200 which means we can use roses more than 200 but not less than 200,  the equation will be:

24 x + 10 y >= 200

Answer:

[tex]24x+10y\geq 200[/tex]

Step-by-step explanation:

Givens:

According to the problem, we can define the number of roses per a centerpiece: [tex]24x[/tex]

The number of roses per bouquet: [tex]10y[/tex]

So, the problem restricts the amount of roses, at least 200, that means, 200 or more than 200 roses. Therefore the expression that represent the amount of roses would be:

[tex]24x+10y\geq 200[/tex]

As you can observe, the inequality includes the 200 roses restriction, and the amount of roses per centerpieces and per bouquet.

Answer:

Step-by-step explanation:

If we perform the indicated multiplication, the highest powered x term will be 4 (as in x^4).  Thus, the total number of roots of this polynomial will be 4.

Answer:

total number of roots =4

Step-by-step explanation:

the total number of roots of each polynomial function using the factored form

[tex]F(x) = (x-6)^2(x+2)^2[/tex]

Given f(x) is in factored form, to get the roots we look at the factors and the exponents.

[tex](x-6)^2[/tex] has exponent 2, so we have two roots 6 and 6

like that [tex](x+2)^2[/tex] gives us two roots because it has exponent 2

So total number of roots for this polynomial function is 4

Answer:

120

Step-by-step explanation:

Using the definition

n[tex]P_{r}[/tex] = n! / (n - r ) !

where n! = n(n - 1)(n - 2) ....... × 3 × 2 × 1

Hence

5[tex]P_{5}[/tex] = 5! / 0! = 5! ← 0! = 1

5[tex]P_{5}[/tex] = 5! = 5 × 4 × 3 × 2 × 1 = 120

In mathematics, the permutation '5P5' equals 1 because there is exactly one way to arrange 5 items in 5 spots.

The problem you are asked to solve involves understanding permutations, which in mathematics, is a way to calculate the number of possible arrangements of a set of items. Specifically, the permutation you are asked to evaluate is written as '5P5'.

In permutation notation, the expression 'nPn' always equals 1, because there are exactly 1 ways you can arrange 'n' items in 'n' spots.

Therefore, the solution to '5P5' is 1.

Answer:  The required numbers are 14 and 7.

Step-by-step explanation:  Given that the sum of two numbers is 21 and their difference is 7.

We are to find the numbers.

Let x and y represents the two numbers.

Then, according to the given information, we have

[tex]x+y=21~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\x-y=7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

Adding equations (i) and (ii), we get

Answer:

12

Step-by-step explanation:

We are given first five multiples of 4 and 6 as shown below and we are to find their least common multiple.

Multiples of 4: 4, 8, 12, 16, 20, . . .

Multiples of 6: 6, 12, 18, 24, 30, . . .

From the given multiples, we can see that the number 12 and 24 are the common multiples which means that these numbers are multiples of both 4 and 6.

So the least common multiple will be 12.

The least common multiple (LCM) of 4 and 6 is 12. This is the smallest multiple that both numbers share.

The least common multiple (LCM) of two numbers is the smallest number that is evenly divisible by both of those numbers. In this case, we are looking for the LCM of 4 and 6.

To find the LCM, we can list the multiples of both numbers and look for the smallest common multiple.

Multiples of 4: 4, 8, 12, 16, 20, ...

Multiples of 6: 6, 12, 18, 24, 30, ...

From the lists, we can see that 12 is the smallest number that appears in both lists. Therefore, the LCM of 4 and 6 is 12.

So, the correct answer is 12. The LCM of 4 and 6 is 12 because it is the smallest number that is evenly divisible by both 4 and 6, as it appears in the list of multiples for both numbers.
