Step-by-step explanation:

each bag has 15 balloons

21 balloon left divide that

by 3 bag cause that is the number of bags you have

So that leaves ya with 7 balloons in each bag

you already took out 8 balloons from each bag

SO ADD 8+7 .... and you get 15

The number of balls that were initially in the bag is 15

Javler bought 3 bags of balloons

He used 8 balloons from each bag

There were 21 balloons left over in the bag

= 21/3

= 7

= 7 + 8

= 15 ballons

Hence there are 15 balloons originally in  the bag

Answer: Step 1 box= 19 (2+3+4+5+5)

Step 2 box= 3.8 (19 divided by 5)

Step-by-step explanation:

You add together the numbers to get 19, the you divide the number by five because you added 5 numbers together.

You had it just right on the bottom. Your equation was perfect. It doesn't matter if you get a decimal number.

0.000000004 = 4 hundred millionths probability Brent will win the jackpot.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

1 desired combination out of 258,890,850. So

[tex]p = \frac{1}{258890850} = 0.000000004[/tex]

9 places after the decimal point is hundred millionths

0.000000004 = 4 hundred millionths probability Brent will win the jackpot.

Answer:

2 cans are cokes.

Step-by-step explanation:

16/1 (total cans) * 1/8 (the amount that are coke) = 16/18 = 2

Answer:

Step-by-step explanation:

x² - 12x + a = (x + b)²

x² - 12x + a = x² + 2xb + b²

-12 = 2b and a = b²

b = -6

a = b² = 36

The value of a is 36 and b = -6.

The polynomial equation whose highest degree is two is called a quadratic equation or sometimes just quadratics. It is expressed in the form of: ax² + bx + c = 0.

The given expression is;

[tex]\rm x^2-12x+a=(x+b)^2[/tex]

The solution of the equation is determined in the folllowing steps given below.

[tex]\rm x^2-12x+a=(x+b)^2\\\\x^2-12x+a=x^2+2xb+b^2\\\\2xb + b^2 = a-12x[/tex]

On comparing the equation

[tex]\rm 2b =-12\\\\b =\dfrac{-12}{2}\\\\b=-6[/tex]

The value of a is;

[tex]\rm a=b^2\\\\b=-6\\\\a=(-6)^2\\\\a=36[/tex]

Hence, the value of a is 36 and b = -6.

The transformations of f(x) when compared to the parent function is the graph of [tex]f(x)=x^2+5[/tex] is moved 5 units up

Transformation of function is transforming a function from one form to another form .

f(x)-> f(x)+a , f(x) will be moved 'a' units up

f(x)-> f(x)-a , f(x) will be moved 'a' units down

f(x)-> f(x-a) , f(x) will be moved 'a' units right

f(x)-> f(x+a) , f(x) will be moved 'a' units left

f(x)-> -f(x), f(x) will be reflected across x-axis

Answer:

Step-by-step explanation:

The B of years it took to the given principal to amount $910 is 3.4 years.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].

Given that, principal =$750, rate of interest =1.9% and amount=$910.

Let the number of years be x and compounded quarterly.

Here, 910=750(1+ 1.9/100)³ˣ

910/750 =(1+0.019)³ˣ

1.213=(1.019)³ˣ

Take the logarithm of both sides of the equation to remove the variable from the exponent.

Exact Form:

x=ln(1.213)/3ln(1.019)

Decimal Form: 3.419

≈ 3.4 years

Therefore, the number of years it took to principal to reach $910 is 3.4 years.

Step-by-step explanation:

Since they both have a negative y and Quardant 4 has a positive x

=============================================================

Explanation:

Notice the double tickmarks on segments WZ and ZY. This tells us the two segments are the same length. Let's say they are m units long, where m is a placeholder for a positive number.

That would mean m+m = 2m represents the length of segment WY, but that's equal to 10 as the diagram shows. We have 2m = 10 lead to m = 5 after dividing both sides by 2.

We've shown that WZ and ZY are 5 units long each. In short, we just cut that length of 10 in half.

-----------------------------------

Let's focus on triangle XYZ. This is a right triangle with legs XZ = unknown and ZY = 5. The hypotenuse is XY = 13.

We'll use the pythagorean theorem to find XZ

a^2 + b^2 = c^2

(XZ)^2 + (ZY)^2 = (XY)^2

(XZ)^2 + (5)^2 = (13)^2

(XZ)^2 + 25 = 169

(XZ)^2 = 169-25

(XZ)^2 = 144

XZ = sqrt(144)

XZ = 12

Segment XZ is 12 inches long.

D. Point G is the center of a circle that can be inscribe in ΔABC

Step-by-step explanation:

To inscribe implies constructing a required shape or figure within a given shape, thus touching the boundaries or sides of the given shape internally.

In the given figure if point G is used as the center of a circle, it would not form an inscribed circle in the given triangle. So that the appropriate answer is Point G is the center of a circle that can be inscribe in ΔABC. Thus, option D is not true.
