Answer:

black: 16/31 blue: 13/31 red 2/31

16 black, 13 blue, 2 red

16+13+2 = 31 total

16/31 is the probability of picking black

13/31 is the probability of picking blue

2/31 is the probability of picking red, so 29/31 is the probability of not picking red (since 31-2 = 29 are not red out of 31 total)

Answer: girls=20, sister=10

Step-by-step explanation:

Let x = the girl's sister's age (present)

Let 2x= the girl's age (present)

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

According to the question

(x+5)(2x+5)=375

Expand parentheses by FOIL (First Outer Inner Last)

2x²+5x+10x+25=375

Combine like term (5x and 10x)

2x²+15x+25=375

Subtract 375 on both sides

2x²+15x+25-375=375-375

2x²+15x-350=0

Find the factors (cross factor)

(x-10)(x+17.5)=0

x=10 or x=-17.5 (rej) ⇔ the age can't be negative

the girl's age is 20, and her sister's age is 10.

If Ava has 34 candy bars, and each box can hold 5 bars, then we need to find out how many boxes that are filled up.

[tex]\bf Step~1:[/tex]

Divide the number of candy bars (34), by the number each box can hold (5)

[tex]\bf\frac{34}{5}=6.8[/tex]

Since we cannot have 6.8 boxes, we have to round down to 6.

[tex]\boxed{\bf Our~final~answer:~6~boxes}[/tex]

[tex]\bf Check~our~answer:[/tex]

To check our answer, we multiply the number of boxes (6), by the number of bars in each box (5), to get 30. We add Ava's extra bars (4), and we get the number we started off with: 34. This proves our answer is correct!

Solved on Desmos graphing calculator ;)

The value of x is 19. Therefore, option C is the correct answer.

From the given figure, the two angles are (7x-8)° and (6x+11)°.

Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight lines. In simple words, vertical angles are located across from one another in the corners of the "X" formed by two straight lines. They are also called vertically opposite angles as they are situated opposite to each other.

Now, (7x-8)° = (6x+11)° (Vertically opposite angles are equal)

⇒ 7x-6x = 11+8

⇒ x = 19°

The value of x is 19. Therefore, option C is the correct answer.

Answer: x = 2 or x = -1

Step-by-step explanation: When you are solving an absolute value equation, you can split the problem up into two separate equations.

The first equation will look just like the original problem,

except for the absolute value signs (2x - 1 = 3).

The second equation will look just like the first,

but the right side will be changed to a negative (2x - 1 = -3).

Now solve each equation from here to get x = 2 or x = -1

Answer:

The water is 208.22ft from the tug boat

Step-by-step explanation:

The governing equation is [tex]y=-0.0055x^2 +1.15x + 5[/tex]

y is the height above the ocean

x is the distance from the tugboat

if y= 6ft, the equation will now become

[tex]6=-0.0055x^2 +1.15x + 5[/tex]

we can arrange this properly to form a quadratic equation by grouping like terms.

[tex]-0.0055x^2 +1.15x -1=0[/tex]

solving quadratically we have two values of x as  208.22ft and 0.873 ft.

We can take a more realistic value as a solution to our problems:

Answer:

D. 0.64

Step-by-step explanation:

The reason I got this answer is because the problem tells us that there is a success rate of .36, so you would subtract .36 from 1 to get .64. The success rate and failure rate should always be equal to 1.

Step-by-step explanation:

The general equation of a straight line graph is y = mx + c, where m is the gradient of the line and c is the y-intercept.

Gradient = (2 - (-18)) / (3 - (-2)) = 20/5 = 4.

So y = 4x + c.

When x = 3, y = 2. (Given in the question)

This means that 2 = 4(3) + c, hence c = -10.

The answer is y = 4x - 10.

Answer:

Tina ate 3/4 of the whole pan of cornbread.

Step-by-step explanation:

Let the amount of cornbread in the initial pan be x.

After the dinner party, Tina has 1/2 of x left; That is 1/2x

If she eats 1/2 of the leftover, that will be 1/2 of 1/2x that is eaten. This will be 1/4x that is eaten.

To find the potion of the whole pan that Tina ate, we will add the potion she ate during the party to the portion of the leftover she ate the next night.

That will be 1/2x + 1/4x =3/4x

Therefore, Tina ate 3/4 of the whole pan of cornbread.

Answer:

The graph with the vertical line.

Step-by-step explanation:

All vertical lines have an undefined slope.  Horizontal lines have zero slope, and diagonal lines have a slope.

When calculating a slope for a vertical line, you would have to divide by zero. The quotient of any number and 0 are undefined, as you cannot divide by zero.  This is what makes vertical lines have an undefined slope.

Answer:

the answers is 6x 10 4

Step-by-step explanation:

The expression 6 x 10 x 10 x 10 x 10 with an exponent would be written as 6(10^4).

The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.

If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

We have been given an expression as

6 x 10 x 10 x 10 x 10

Here we can see the base 10 multiplied by itself 4 times.

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^b \implies b= c \: \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]

The expression 6 x 10 x 10 x 10 x 10 with an exponent would be written as 6(10^4).

y = -0.2*x^2 is a vertical dilation of scale factor 0.2 followed by a reflection over the x-axis of y = x^2

We have two functions:

f(x) = x^2

g(x) = -0.2*x^2

The transformations used are:

Reflection over the x-axis.

For a function f(x), a reflection over the x-axis is written as:

g(x) = -f(x).

Vertical dilation.

For a function f(x), a vertical dilation of scale factor k is written as:

g(x) = k*f(x).

So here we can see that we have a vertical dilation of scale factor 0.2, followed by a reflection over the x-axis.

g(x) = -0.2*f(x).

So, g(x) opens in the opposite direction than f(x), and grows slower (because of the dilation).
