Answer:

Step-by-step explanation:

2 ft

Step-by-step explanation:

The height from which the beach ball was thrown happens when t = 0. So setting t = 0 to get y, we get

y = [-16(0) - 2](0 - 1)

= (-2)(-1)

= 2 ft

Therefore, the ball was thrown from a height of 2 ft.

Answer:

  2 2/3

Step-by-step explanation:

  -2 1/3 - (-5)

  = -2 1/3 + 5 . . . . . subtraction is the same as adding the opposite

  = (5 -2) -1/3 . . . . . -2 1/3 = (-2) +(-1/3)

  = 3 -1/3 . . . . . . . . . deal with the integer and fractional parts separately

  = 2 2/3

Answer: y=5/3x-4

Step-by-step explanation:

Hi, you could find the slope with any 2 points on the line. For accuracy, I will choose the points (6, 6) and (0, -4), meaning when x =6, y=6, and when x=0, y=-4. Then you can set up an equation. Because the line on this graph is linear (meaning straight), the form of the equation would be y=ax+b. (If it was a parabola, it would be y=ax^2+bx+c).

y=mx+b (Or some people prefer y=ax+b, but the same thing).

Now, plug in the x and y values, getting:

6 = 6m+b and -4=0*m+b

When you simplify, you will get that b is -4, and then m is 5/3

So the equation is y=5/3x-4

You can plug the numbers of x and y in to check your answer.

Hope this helps!

Answer:

118419,54

Step-by-step explanation:

Primero, convierta R como porcentaje en r como decimal

r = R / 100

r = 16/100

r = tasa de 0,16 por año,

Luego resuelve la ecuación para A

A = P (1 + r / n) ^ nt

A = Cantidad =?

P = Principal = 80000

R = 16%

n = Compuesto trimestralmente = 4

t = tiempo en años

= 2 años y 6 meses

12 meses = 1 año

6 meses = x

x = 6/12 = 0,5

t = 2.5 años

A = 80000,00 (1 + 0,16 / 4) (4) ^ (2,5)

A = 80000,00 (1 + 0,04)^ (10)

A = $ 118419,54

What is an equation? In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value. The most basic and common algebraic equations in math consist of one or more variables.

Answer:

276 Guests

Step-by-step explanation:

Calculation to determine how many guest were at the wedding

Guests that choose beef =1/3

Guests that choose chicken= 5/12

Guests that choose vegetarian=69

Now let calculate the how many guest were at the wedding

Let x represent the numbers of guest that were present at the wedding

Hence,

x/3 + 5x/12 + 69 = x

9x/12 + 69 = x

12x/12 - 9x/12 = 69

3x/12 = 69

x/4 = 69

x=69*4

x = 276 guests

Therefore the numbers of guests that were at the wedding is 276

Answer: 276

Step-by-step explanation: Let “x” be the number of guest.

1/3 x +5/12x + 69 = x Simplifying and solving for x … where x = 276

1/3(276) + 5/12(276) + 69 = 276

92 + 115 + 69 = 276

Answer:

sample

or spot check

Step-by-step explanation:

there are quite a number of different terms that can be used depending on the specific scientific field you are working in.

but "sample" should be the most common one for a random selection of a subset of the whole set.

Answer:

16

Step-by-step explanation:

Number of boys who played cricket=12

ie, it is the 3 times of boys who played tennis

then,

Number of boys who played tennis =12÷3 =4

therefore,

Total number of boys=Number of boys who played cricket +Number of boys who played tennis

=12+4=16

To do the following I first listed the numbers from least to greatest

mean: (also known as average) is 7 just add all the numbers together and divide by the amount of numbers there are which is 77/11

median: 5 it's the middle number (5, 5, 6)

mode: 2 the number that appears the most

range: 16 difference between the highest value and the lowest (18-2)

quartile 1: 2 median of the lower half

quartile 3: 9 median of the upper half

interquartile range: 7 (Q3-Q1)

hope this helped :)

Answer:

55°

Step-by-step explanation:

if the middle is straight, then x+35°=90°

Answer:

D) Identifies the transaction and is located at the top right corner of the check

Step-by-step explanation:

The check number on a check is the number located at the top right corner of the check, and it can also be found at the bottom of the check, located in lower right corner after the routing number and the account number

The check number aids in the tracking and identifying bank transactions such as to identify checks that the bank has processed and to know outstanding checks that are yet to be processed.

The check number also aids in balancing of the checkbook.

Therefore, the check number on a check identifies the transactions and is located at the top right corner of the check.

Answer:

(1, 1 )

Step-by-step explanation:

Given the 2 equations

2x - 4y = - 2 → (1)

3x + y = 4 → (2)

Multiplying (2) by 4 and adding the result to (1) will eliminate the y- term

12x + 4y = 16 → (3)

Add (1) and (3) term by term to eliminate y

14x + 0 = 14

14x = 14 ( divide both sides by 14 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (2)

3(1) + y = 4

3 + y = 4 ( subtract 3 from both sides )

y = 1

solution is (1, 1 )

Answer:

B. 144/720

Answer:

x=2, y = -4.

or as an ordered pair it is (2, -4).

Step-by-step explanation:

-x + 6y = -26

x + 5y =  -18      Add these 2 equations to eliminate x:

0 + 11y = -44

y = -44/11 = -4.

Now substitute y = -4 in the first equation:

-x + 6(-4) = -26

-x - 24 = -26

-x = -26 + 24 = -2

x = 2.

Check the result by substituting in equation 2:

x + 5y = 2 + 5(-4) = 2 - 20 = -18  - checks out.

Probability that both Rebecka and Aaron select poodles is  4/81

It is a branch of mathematics that deals with the occurrence of a random event.

Given,

A pet store has 9 puppies.

includes 2 poodles, 5 terriers, and 2 retrievers.

Rebecka selects one puppy at random.

The probability of selection one pet from store is 1/9

After Rebecka selects one puppy at random pet store replaces the puppy with a puppy of the same breede. Now store has same number of pets.

Aaron chooses a puppy at random.

The probability of Aaron selecting a pet is 1/9.

As they both selects a poodle,

Rebecka : Probability of selection one poodle from store is 2/9

Aaron: Probability of selection one poodle from store is 2/9

The probability that both Rebecka and Aaron select poodles is 2/9 × 2/9 = 4/81

Hence probability that both Rebecka and Aaron select poodles is  4/81
