Answer:

Answer: b 200 yards

Step-by-step explanation:

Scaling

Real magnitudes can be scaled up or down to adapt to the size of a sheet of paper or the screen of a computer or phone.

Catherine knows she is 50 yards from the school and it's shown as a distance of 3/4 inch on her phone map.

We can calculate the scaling factor from the real distance to the map distance by dividing:

[tex]\displaystyle \frac{50}{\frac{3}{4}}=\frac{200}{3}[/tex]

Now she sees that she's 3 inches from home on the same map. This is equivalent to a real distance of:

[tex]\displaystyle 3\cdot \frac{200}{3}=200[/tex]

Catherine is 200 yards from her home.

Answer: b 200 yards

Answer:

Step-by-step explanation:

6/3 is 2 cups.

2/3 times 3 is 2.

12 of the 2/3 cups is your answer

That is my way of thinking. If you want the answer basically you divide 8 by 2/3. When you divide a fraction you multiply by its reciprocal.

8  3   =24   =  12

1   2     2         1

8 times 3/2 is equal to 24/2 or 12

Answer:

Year - (1993 - 1995)

Step-by-step explanation:

Rate of change in the number of toys sold = [tex]\frac{\text{change in number of toys sold}}{\text{Time interval}}[/tex]

In the interval (1990 - 1993),

Rate of change in number of toys sold = [tex]\frac{32000-20000}{1993-1990}[/tex]

                                                                = [tex]\frac{12000}{3}[/tex]

                                                                = 4000

In the interval (1993 - 1995),

Rate of change = [tex]\frac{42000-32000}{1995-1993}[/tex]

                          = [tex]\frac{10000}{2}[/tex]

                          = 5000

In the interval (2000 - 1995),

Rate of change = [tex]\frac{57000-42000}{2000-1995}[/tex]

                          = [tex]\frac{15000}{5}[/tex]

                          = 3000

In the interval (2006 - 2000),

Rate of change = [tex]\frac{63000-57000}{2006-2000}[/tex]

                          = [tex]\frac{6000}{6}[/tex]

                          = 1000

Therefore, rate of change in the number of toys sold is greatest in the interval (1993 - 1995).

Step-by-step explanation:

Lets take the number of songs he download = x

So $1.29x = $20

So "x" = 20/4.29 = 15.5

So songs he can purchase = 15 songs

Answer:

Step-by-step explanation:

Right Triangle Similarity

Acute Angle Similarity

If one of the acute angles of a right triangle is congruent to an acute angle of another right triangle, then by Angle-Angle Similarity the triangles are similar.

In the figure, ∠M≅∠Y , since both are right angles, and ∠N≅∠Z .

So, ΔLMN∼ΔXYZ .

Leg-Leg Similarity

If the lengths of the corresponding legs of two right triangles are proportional, then by Side-Angle-Side Similarity the triangles are similar.

In the figure,  ABPQ=BCQR .

So, ΔABC∼ΔPQR .

Hypotenuse-Leg Similarity

If the lengths of the hypotenuse and a leg of a right triangle are proportional to the corresponding parts of another right triangle, then the triangles are similar. (You can prove this by using the Pythagorean Theorem to show that the third pair of sides is also proportional.)

In the figure, DFST=DESR .

So, ΔDEF∼ΔSRT .

Taking Leg-Leg Similarity and Hypotenus-Leg Similarity together, we can say that if any two sides of a right triangle are proportional to the corresponding sides of another right triangle, then the triangles are similar.

Answer:

A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.

Answer: If you mean at least one of the dice shows an odd number, then since there's a 0.25 = 0.5 x 0.5 probability of both dice being even, there's a 1 - 0.25 = 0.75 probability at least one of the dice is odd. However.. The probability that the first die is even and the total of the two dice is 8 is 3/36 since (6,2), (2,6), and (4,4) are 3 of the 36 outcomes in which the first die is even and the total is 8. sorry I could only explain, hopefully you can figure it out from here :(

Answer:

Mr. Dairo can produce 20580 pieces of Papaya rosette in two weeks.

Step-by-step explanation:

Papaya rosette pieces on first day = 5890

Papaya rosette Pieces on second day = 7020

Papaya rosette Pieces of third day = 8150

Let

[tex]a_1 = 5890\\a_2 = 7020\\a_3 = 8150[/tex]

We can check if these numbers are part of a sequence.

In order to check, common difference will be found first.

[tex]d = a_2-a_1 = 7020-5890 = 1130\\d =a_3-a_2 = 8150-7020 = 1130[/tex]

It can be observed that the common difference is same. When the common difference is same, the sequence is said to be an arithmetic sequence.

The formula for arithmetic sequence is given by:

[tex]a_n = a_1+(n-1)d[/tex]

Putting the values

[tex]a_n = 5890+(n-1)(1130)\\a_n = 5890+1130n-1130\\a_n =4760+1130n[/tex]

The formula for nth term can be used to find any term. As we have to find the number of papaya rosette pieces after two weeks which means that we need to find the number of pieces on 14th day.

So,

[tex]a_{14}= 4760+1130(14)\\a_{14} = 4760+15820\\a_{14} = 20580[/tex]

Hence,

Mr. Dairo can produce 20580 pieces of Papaya rosette in two weeks.

Answer:

4/-2

Step-by-step explanation:

Start at a point where the line intersects a firm coordinate like y=2 then use rise/run rise is vertical and run is horizontal count from the intersection up to where the line intersects another firm point in this case y=6  then count the run which lands on x=-2 y=6 which gives you the slope of 4/-2

Solve for x

Step-by-step explanation:

by simplifying both sides of the equation, then isolating the variable.

Answer:

Step-by-step explanation:

Let the two digits be x and y, where x is the tens digit and y is the units (ones) digit.

Then the number is 10x + y.

From the question,

The sum of the digits in a two digit number is 14,

That is, x + y = 14 ....... (1)

Also, from the question,

If you reverse and double the original number, and then add the result to the original number, the sum is 222

If the number is reversed, the new number will be 10y + x; and if this is doubled, we will get 2(10y + x).

Now, if this is added to the original number (10x + y), the sum is 222.

That is,

2(10y + x) + (10x + y) = 222

Then,

20y + 2x + 10x + y = 222

12x + 21y = 222 ........ (2)

Now, we will bring the two equations together and solve simultaneously.

x + y = 14 ....... (1)

12x + 21y = 222 ........ (2)

From equation (1)

x + y = 14

Then, x = 14 - y ...... (3)

Substitute the value of x in equation (3) into equation (2)

12x + 21y = 222

12(14 - y) + 21y = 222

168 - 12y + 21y = 222

168 + 9y = 222

9y = 222 - 168

9y = 54

∴ y = 54/9

y = 6

To determine x, substitute the value of y into equation (3)

x = 14 - y

∴ x = 14 - 6

x = 8

∴ x = 8 and y = 6

Recall that, the two digits are x and y, where x is the tens digit and y is the units (ones) digit.

Hence, the original number is 86.

Answer:

-2(p+3)+4p = 2p - 6

Step-by-step explanation:

Step 1: Distribute the -2 to the (p) and (3) which equals = -2p-6

Step 2: Combine Like Terms: -2p - 6 +4p --> 2p - 6
