Answer:

Options (A) and (B)

Step-by-step explanation:

Speed of the leatherback sea turtle = 21.92 miles per hour

If the sea turtle travels distance 'd' in 't' hours,

Speed [tex]=\frac{\text{Distance}}{\text{Time}}[/tex]

Speed that is less than 21.92 mph are 2.192 mph and 20 mph,

For speed = 20 mph

20 = [tex]\frac{d}{t}[/tex]

d = 20t

For speed = 2.192 mph

2.192 = [tex]\frac{d}{t}[/tex]

d = 2.192t

Therefore, Options (A) and (B) are the correct options.

Answer:

$753.14

Step-by-step explanation:

7.51% + 1.2% = 8.71%

8.71% off of $825 is $753.14

Answer:

$753.1425 or $753.14

Step-by-step explanation:

7.51% of $825 is $61.96 (You do this by taking the original of $825 and multiplying it by the decimal .0751 (which is the decimal form of 7.51%)

And 1.2% of $825 is $9.9 (Same formula from above, but multiply by .012)

Answer:

x = 3

Step-by-step explanation:

5x - 3 + 2x = 5x + 3

subtract 5x from both sides

5x - 5x - 3 + 2x = 5x - 5x + 3

-3 + 2x = 3

add 3 to both sides

-3 + 3 + 2x = 3 + 3

2x = 6

divide both sides by 2

2x/2 = 6/2

x = 6/2

x = 3

Answer:

x = 3

Step-by-step explanation:

5x - 3 + 2x = 5x + 3. that is

7x - 3 = 5x + 3 ( subtract 5x from both sides )

2x - 3 = 3 ( add 3 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

The square route of 64 is 8.

8x8=64

Answer:

The square root of 64 is 8

Step by step explanation:

8 x 8 = 64

Answer: see below

Step-by-step explanation:

Set up two equations, one for each scenario

88w + 21b = 5840

84w + 82b = 9044

Use one equation and isolate one of the variables. We'll isolate w in the first equation.

88w + 21b = 5840

88w = 5840 - 21b

w = (5840 - 21b)/88

Then substitute that into the second equation.

84w + 82b = 9044

42w + 41b = 4522 (simplified)

42((5840 - 21b)/88) + 41b = 4522

21((5840 - 21b)/44) + 41b = 4522 (simplified)

(122640 - 441b)/44 + 1804b/44 = 4522

(122640 - 441b + 1804b)/44 = 4522

122640 + 1363b = 198968

1363b = 76328

b = 56

Now that we know belts are $56, we can substitute that back into any equation and solve for w.

w = (5840 - 21b)/88

w = (5840 - 21(56))/88

w = (5840 - 1176)/88

w = 4664/88

w = 53

Given :

A building casts a shadow 46 feet long.

At the same time, a 36 foot tall flagpole costs a shadow of 9.2 feet long.

To Find :

The height of the building.

Solution :

Since, all readings are taken in same time.

Ratio of height and shadow remains for all objects.

Let, height of building is H.

So,

[tex]\dfrac{H}{46}=\dfrac{36}{9.2}\\\\H = \dfrac{36}{9.2}\times 46\\\\H = 180\ feet[/tex]

Therefore, height of the building is 180 feet.

Answer:

B

Step-by-step explanation:

This is just a guesstimate because $200 is a $12 fee and all the other ones are high assuming the higher the item price is the high the fee will be, again this is a guesstimate!

Answer:

y= 77° x=103°

Step-by-step explanation:

x=103° Alternate angles are equal

y=77° angles on a straight line sum to 180° (180°-103°=77°)

Answer:

For x, we can justify that x=103° and for y, we can justify that it equals 77°.

Step-by-step explanation:

X°: VERTICAL ANGLE THEOREM, or if angles are opposite of each other and are formed by two intersecting straight lines, then they are congruent.

Thus, x°=103°

Y°: SUPPLEMENTARY ANGLE THEOREM, or if two angles are supplementary to the same angle, then the two angles are said to be congruent.

Thus, y°=77°

Step-by-step explanation:

The expression for the area of three rows of m squares with side lengths of m centimeters is [tex]3m^3[/tex] square centimeters.

To find the area of three rows of m squares with side lengths of m centimeters, determine the total number of squares.

Each row consists of m squares, and there are three rows in total. Therefore, the total number of squares is 3m.

The area of each square is given by the formula

[tex]A = s^2[/tex],

where s is the length of the side.

Multiply the area of one square by the total number of squares:

Area = (Area of one square)  (Total number of squares)

Area = [tex]m^2[/tex] * 3m

Area = [tex]3m^3[/tex]

Therefore, the expression for the area is [tex]3m^3[/tex] square centimeters.

The simplified expression for the area of three rows of m squares with side lengths of m centimeters is 3 * m^3 square centimeters.

To find the area of three rows of m squares with side lengths of m centimeters, we need to determine the total area covered by the squares.

Each row consists of m squares, and each square has a side length of m centimeters. Therefore, the length of each row is m * m = m^2 centimeters.

Since there are three rows, the total length covered by the rows is 3 * m^2 centimeters.

To find the area, we need to multiply the total length by the width, which is also m centimeters. Thus, the area of the three rows of squares is:

Area = Length * Width

Area = (3 * m^2) * m

Area = 3 * m^3 square centimeters
