Answers

Answer: 
Choice B) 8*sqrt(3)

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

Explanation:

First we need to find y
It turns out we can set up the proportion 
4/y = y/12
since the two inner smaller triangles are similar triangles

Solve for y by cross multiplying
4/y = y/12
4*12 = y*y
48 = y^2
y^2 = 48
y = sqrt(48)

Now use this y value to find x
Use the pythagorean theorem. Focus on the smaller triangle on the right side
a^2 + b^2 = c^2
y^2 + 12^2 = x^2
(sqrt(48))^2 + 12^2 = x^2
48 + 144 = x^2
192 = x^2
x^2 = 192
x = sqrt(192)
x = sqrt(64*3)
x = sqrt(64)*sqrt(3)
x = 8*sqrt(3)

So that's why the answer is choice B

The ability to roll your tongue is inherited genetically from parents if either parent has the dominant trait T. Children of two parents without the trait will not be able to roll their tongues. Part A: Show how the combinations can be modeled by the square of the sum. Part B: Predict the percent of children that will both have dominant genes, one dominant gene, and both recessive genes

Answers

a. If a person has the genetic combination Tt. Then, half of his/her genes are the dominant trait T and the other half are the recessive trait t. So, his/her genes can be represented by 0.5T + 0.5t. If both parents have the genetic combination Tt, then the outcomes for their children can be modeled by the sum of the square: b. There are four total outcomes. For children to have two dominant genes, they would have TT, which is a 25% probability. For children to have one dominant gene, they would have Tt, which is a 50% probability. For children to have two recessive genes, they would have tt, which is a 25% probability. 

What is the relative maximum and minimum of the function? f(x) = 2x2 + 28x - 8

Answers

There is a minimum because the a is positive so that means the graph is upwards, the minimum would be -106!
i hope this helps

Answer:

Minimum: y=-106. Maximum: infinite

Step-by-step explanation:

The function described is a parabola, written in the form:

[tex]f(x)=ax^2 +bx+c[/tex]

with:

[tex]a=2\\b=28\\c=-8[/tex]

First of all, we notice that the parabola is upward, because the sign of the coefficient of the second-order term (a) is positive (in fact, a=2). Therefore, it has a minimum value of y. The x corresponding to the vertex of the parabola is given by:

[tex]x_v=-\frac{b}{2a}=-\frac{28}{2\cdot 2}=-7[/tex]

And substituting into f(x), we find the minimum value of y:

[tex]f(-7)=2(-7)^2+28(-7)-8=98-196-8=-106[/tex]

While the parabola has no maximum value, since it goes to infinite as x becomes larger.

Consider the statement below. More than 20 students participated in a drawing competition. Which number line best represents the statement?

Answers

A because the circle is open when it is more than or less than and it is shaded when it is less than or equal to or greater than or equal to. Hope this helped!

Answer:

The number line that best represents this statement is:

                       Option: A

Step-by-step explanation:

We are given a statement that:

More than 20 students participated in a drawing competition.

This means that when this statement is represented on the number line the region that is covered is:

(20,∞)

Since the more than 20 students means that 20 is not included and all the numbers greater than 20 are included.

Also, on the number line the shaded region lie to the right of 20 and there is a open circle at 20 as 20 is not included in the domain.

Hence, option: A is the correct answer.

A car travels 444 km in 7 hours (with a constant speed).How far can it travel in 5 hours (with the same speed)?

Answers

first divide to find the unit rate to find out how far they travel in one hour. then multiply the unit rate with the hours to get the miles traveled
Final answer:

The car can travel 317.15 km in 5 hours given its speed remains constant at 63.43 km/h which is calculated based on the 444 km it travels in 7 hours.

Explanation:

To solve this problem, we need to calculate the rate of speed of the car first. The speed of the car is found by dividing the total distance by the time.
So, the speed will be 444 km / 7 hours = 63.43 km/h.

With this constant speed, we can determine how far the car could travel in 5 hours by multiplying the speed by the time:
Thus, the distance it can travel in 5 hours is 63.43 km/h * 5 h = 317.15 km.

Answer:  

The required factorized form of the given quadratic equation is :

4x·(2x + 3)

Step-by-step explanation:

The quadratic equation is given to be :

8x² + 12x

Now, we need to find the factored  for of the given quadratic equation.

⇒ 8x² + 12x

Taking 4 common from both the terms

⇒ 4(2x² +3x)

Now, Taking x common from both the terms which are inside the bracket

⇒ 4x·(2x + 3)

⇒ Now, This equation cannot be factorized further

Hence, The required factorized form of the given quadratic equation is :

Answers

Answer:

25.5÷3=8.5

answer is 8.5....

Answer: C 8.5

Step-by-step explanation:

We can use the formula:

time = (number of revolutions) / (rate of revolution)

Substituting the given values, we get:

time = 25.5 / 3

time = 8.5

Therefore, the Carousel will take 8.5 minutes to spin 25.5 times.

a company sells snack bags that contain a mixture of almonds and walnuts. there are 15 almonds per bag and 9 walnuts per bag. if x represents the number of snack bags the company sells, which of the following equations can be used to find the total number of nuts needed to fill the snack bags?

Answers

Answer:

y = 21x

Step-by-step explanation:

12x for the almonds

9x for the walnuts

12x + 9x is:

21x total

So, the formula should be:

y = 21x

Final answer:

The equation is Total nuts = 24 nuts per bag * x bags.

Explanation:

To find the total number of nuts needed to fill the snack bags the company sells, we need to calculate the sum of almonds and walnuts in each bag and then multiply that by the number of snack bags sold (represented by x).

Each snack bag contains:

15 almonds9 walnuts

The total number of nuts per bag is:

15 almonds + 9 walnuts = 24 nuts per bag

Thus, if x represents the number of snack bags sold, the equation to find the total number of nuts required is:

Total nuts = 24 nuts per bag * x bags

An isosceles trapezoid has base angles of 45 degrees and bases of length 9 and 15. The area of the trapezoid is

Answers

The trick here is to find the height. 
The difference between the two base lengths is 15 - 9 = 6
There is a 3 inch difference between the end of the shortest base and the end of the longest base at each end of the shortest base. You are going to have to read that sentence a couple of times. 
Because the base angles are 45°, the height = the 3 inch difference between the ends of the 2 bases.

L1 = 9
L2 = 15
h = 3
Area = (L1 + L2)*h/2
Area = (9 + 15) * 3 /2
Area = (24) * 3/2

The sides of a triangle are 7, 4, n. If n is an integer, state the largest and smallest possible values of n.

smallest value is-
largest value is-

Answers

Answer:

11 > n > 4

Step-by-step explanation:

Given any two sides of a triangle, we now that the sum of such sides MUST be greater than the measure of the remaining side. This is, given the three sides a, b and c, it must be that:

a + b > c

a + c > b

b + c > a

For our case:

7 + 4 > n (1) ---> 11>n

7 + n > 4 (2)

4 + n > 7 (3)

The 1 inequality says that the n side MUST be less than 11.

Now, pick the (3) inequality and subtract 4 in both sides:

4 + n  -4 > 7 - 4

n > 3

So, the n side must be grater than 3.

Thus, the solution is:

11 > n > 3

As we are working with integers we now that the grater integer larger than 3 is 4, and the greater integer less than 11 is 10. So, the side must be equal or greater to 4 and equal or less than 10:

10 >= n >= 4
