Which of the following shows the correct match of the box numbers and the genotype of the offspring?

Answers

Technically a biology question but if you create the chart all 4 types will be Tt because the Male has the genotype of TT so they will each have a large T in each box (like making a multiplication table). and the female has tt so the only possibility is a large T with a small t in all four squares because there are both homogenous genotypes.

If five bags of mulch covers 32 square feet, how many square feet could 16 bags covers?

Answers

Answer:

102.4 square feet

Step-by-step explanation:

(32/5)*16=102.4

Final answer:

One bag of mulch covers 6.4 square feet. Therefore, 16 bags will cover 102.4 square feet.

Explanation:

To find out how many square feet 16 bags of mulch will cover, we need to first determine the coverage of one bag. If 5 bags cover 32 square feet, then one bag covers 32 ÷ 5, which equals 6.4 square feet. Multiplying the area covered by one bag by 16 bags gives us a total coverage, of 6.4 × 16, which equals 102.4 square feet. Therefore, 16 bags of mulch will cover 102.4 square feet.

At a local fitness center, members pay an $8 membership fee and $3 for each aerobics class . Nonmembers pay $4 for each Aerobics class. For what number of aerobics classes will the cost for members & nonmembers be the same?

Answers

This problem is an example of solving equations with variables on both sides. To solve, we must first set up an equation for both members and nonmembers.

Since members pay $3 for each aerobics class, we can represent this part of the equation as 3c. Members also pay a one time $8 membership fee, so we just add the 8 to the 3c:

3c + 8

Since nonmembers pay $4 for each aerobics class, we can represent this part of the equation as 4c. They do not have to pay a one time membership fee, so our equation will just be:

4c

To determine when the cost (c) of the aerobics class will be the same for both members and nonmembers, we set the two equations equal to each other:

3c + 8 = 4c

Then, we solve for c. First, the variables must be on the same side of the equation. We can do this by subtracting 3c from both sides of the equation:

8 = 1c.

Last, we divide both sides by 1. So c = 8.

This means that the cost of classes will be the same for members and nonmembers at 8 classes. If we want to check our answer, we can plug 8 back into each equation:

3c + 8
= 3 ( 8 ) + 8
= 24 + 8
= 32

4c
= 4 ( 8 )
= 32

Percy is plotting points on a graph. The ratio of y-value to x-value is 2 to 3 for each point. What will be the x-value of a point with a y-value of 18?

Answers

It is 27 because if you do 9 times 2 you get 18 so you would do 9 times 3 which is the value of x, which is equal to 26

Answer: Value of x = 27

Explanation:

Percy is plotting a coordinate on the graph.

Now the ratio of y-value to x-value is 2 to 3 for each point.

Suppose Value of is 3a and y value is 2a

So, the coordinate of the point is (3a,2a)

Now we find the x value of the coordinate when value of y is 18.

2a is same as 18

2a = 18

a = [tex] \frac{18}{2} [/tex]

a = 9.

Now find the x ordinate

put the value of a=9 into 3a

3a = 3(9) = 27

So the final answer is :

Value of x = 27 when value of y = 18

The given question is a typical example of mathematical puzzles. Mathematical puzzles are mathematical problem given to pupils, students for recreational experience and more.

Further Explanation

Mathematical puzzles further enhance the creativity of students, as it deals with their logical reasoning.

Mathematical puzzles also has do with the practical usage of order of operations i.e. BODMAS (which is an acronym of Bracket, Of, Division, Multiplication, Addition, Subtraction) to derive solutions for existing problems.

It can be observed from the above given mathematical puzzle expression that Multiplication and Addition are in use in that order.

The two figures are multiplied and added together and then placed together to derive a final

5 + 3 = 158

5 x 3 ~ 5 + 3 = 15 ~ 8 = 158

9 + 1 = 910

9 x 1 ~ 9 + 1 = 9 ~ 10 = 910

8 + 6 = 4814

8 x 6 ~ 8 + 6 = 48 ~ 14 = 4814

4 + 4 = 168

4 x 4 ~ 4 + 4 = 16 ~ 8 = 168

Therefore,

7 + 3 = 2110

7 x 3 ~ 7 + 3 = 21 ~ 10 = 2110

Scientists believe that there is an extremely massive black hole at the center of the Milky Way. To find out how many times more massive than the Sun a black hole with a mass of 7.36 x 10³⁶ kg is, you can divide its mass by the mass of the Sun.

Use foil to explain how to find the product of (a+b)(a-b). Then describe a shortcut that you could use to get this product without using foil.

Answers

FOIL stands for Front Outter Inner Last

F- multiply the first two terms axa= a^2
O- multiply the two terms on the outside a x -b= -ab
I- multiply the two inner (middle) terms - b x a= ab
L- multiply the last variable in each term= b^2

A shortcut without using FOIL is called the difference of squares and can be rewrote as (a^2-b^2)

Using the FOIL method -
Firsts: a×a= a^2
Outers: a×-b= -ab
Inners: b×a= ab
Lasts: b×-b= -b^2

Combine -
a^2-ab+ab-b^2
= a^2-b^2

This particular pair of binomial brackets with a + and a - in them can be expanded with the difference of two squares:
(a+b)(a-b) = a^2-b^2

Read the passage. excerpt from Eothen by Alexander Kinglake I went to see and to explore the Pyramids.
