Answer: There are 13 gamblers who played exactly two games.

Step-by-step explanation:

Since we have given that

Number of gamblers played black jack, roulette and poker = 5

Number of gamblers played roulette and poker = 8

Number of gamblers played black jack and roulette = 11

Number of gamblers played only poker = 12

Number of gamblers played poker = 24

Number of gamblers who played only roulette and poker is given by

$8-5=3$

Number of gamblers who played only black jack and roulette is given by

$11-5=6$

Number of gamblers who played only poker and black jack is given by

$24-(12+3+5)\\\\=24-20\\\\=4$

So, the number of gamblers who played exactly two games is given by

$3+6+4=13$

Hence, there are 13 gamblers who played exactly two games.

Use the properties of real numbers to rewrite the expression. 2/5 * (-7) * 5/2

Mama L [17]

For this case we have the following expression:

$\frac{2}{5}*(- 7)*\frac{5}{2}$

Using the associative property we can rewrite the expression in the following way:

$(\frac{2}{5}*\frac{5}{2})*(-7)$

Finally, simplifying we have:

$(1) (- 7)$

$-7$

Answer:

Rewriting the expression we have that the result is:

d. -7

Answer: 100 square units.

Step-by-step explanation:

Given: Jernel has to figure out the area of her square garage.

She knows that one side of the garage is equal to the length of her rabbit pen.

Now, the length of the rabbit pen = 10 units

Then , the length of the garage will be 10 units

Now, Area of square = $\text{(side)}^2=10^2=100\text{units}^2$

Hence, the area of the garage = 100 square units.

Is this answer right?? If not what’s the real answer? I’m trying to practice for my STAAR.

Area of rectangle

21m^2

Area of one triangle

divide length of 7 by 2 (3.5)

gives you length b (unknown side that is not hypotenuse)

then multiply by width of triangle (4)

3.5 * 4 = 14

and in this situation there is no need to divide by two, because you essentially have one full square from both the triangles. this only works when both triangles are the same.

add the area of the rectangle

14+21= 35

35m^2

Solve the equation 4x^2 + 24x + 13 = 2x^2+ 6x to the nearest tenth.

Licemer1 [7]

Answer:

-0.8 and -8.2

Step-by-step explanation:

To solve a quadratic you first need to have one side of the equation equal to zero (because x-intercepts are when y is zero).

4x^2 + 24x + 13 = 2x^2 + 6x

2x^2 + 18x + 13 = 0

Then you can use the quadratic formula to solve for x. You will then come to

-18 ± sqrt(220) / 4

This will simplify out (rounding to the nearest tenth) to -0.8 and -8.2

You deposit $2000 each year into an account earning 7% interest compounded annually. How much will you have in the account in 30

SVETLANKA909090 [29]

The amount that will be in the account after 30 years is $188,921.57.

<h3>How much would be in the account after 30 years?</h3>

When an amount is compounded annually, it means that once a year, the amount invested and the interest already accrued increases in value. Compound interest leads to a higher value of deposit when compared with simple interest, where only the amount deposited increases in value once a year.

The formula that can be used to determine the future value of the deposit in 30 years is : annuity factor x yearly deposit

Annuity factor = {[(1+r)^n] - 1} / r

Where:

r = interest rate
n = number of years

$2000 x [{(1.07^30) - 1} / 0.07] = $188,921.57
