Answer:

Explained below

Step-by-step explanation:

In naming a segment, we are essentially naming a line that has definite starting and endpoints. For example if the starting point of the segment is A and the endpoint is B, we can name it "segment AB".

In another example, a segment can be named with a single letter. For example the point from A to B can be referred to as "segment y" if AB is part of maybe a square.

Whereas, in writing a distance, we are essentially writing the measurement of length between the two endpoints. For example if the distance between AB is 20 metres, we can write distance between AB = 20 metres

Answer:

Uncle's earnings is $2400

Step-by-step explanation:

Represent his uncle's earnings with x

$600 less than twice what your uncle earns is represented as:

[tex]2x - 600[/tex]

Since, his aunt's earnings is $4200.

We have:

[tex]2x - 600 = 4200[/tex]

Add 600 to both sides

[tex]2x - 600 + 600= 4200 + 600[/tex]

[tex]2x = 4800[/tex]

Solve for x

[tex]x = 4800/2[/tex]

[tex]x = 2400[/tex]

Hence, His uncle's earnings is $2400

Answer:

13.93

Step-by-step explanation:

Meal = 54.65

Sales tax = 8%

= 8/100 * 54.65 + 54.65

= 0.08 * 54.65 + 54.65

= 4.372 + 54.65

= 59.022

Tip = 18% of the meal and tax

= 18/100 * 59.022 + 59.022

= 0.18 * 59.022 + 59.022

= 10.62396 + 59.022

= 69.64596

Total people in the holcomebe family = 5

Cost of meal per person =

69.64596 / 5

Answer:

9.25

Step-by-step explanation:

The quotient of 37 divided by 4 is 9 with a remainder of 2, or written as a mixed number, it is 9 2/4 or 9 1/2.

To solve 37 divided by 4 step by step:

Step 1: Divide the first digit of the dividend (37) by the divisor (4):

37 ÷ 4 = 9

Step 2: Multiply the quotient (9) by the divisor (4) to get the product:

9 × 4 = 36

Step 3: Subtract the product (36) from the dividend (37) to find the remainder:

37 - 36 = 1

Step 4: Bring down the next digit (0) from the dividend to the remainder:

Remainder: 10

Step 5: Divide the new number (10) by the divisor (4):

10 ÷ 4 = 2

Step 6: Multiply the new quotient (2) by the divisor (4) to get the product:

2 × 4 = 8

Step 7: Subtract the product (8) from the remainder (10) to find the new remainder:

10 - 8 = 2

Step 8: Since the remainder (2) is less than the divisor (4), we can stop here.

Therefore, the quotient of 37 divided by 4 is 9 with a remainder of 2, or written as a mixed number, it is 9 2/4 or 9 1/2.

Answer:

Step-by-step explanation:

We know that the volume of a sphere/globe is given as

V=4 /3πr^3

but the circumference is expressed as

C=2πr

solving for r given  that C=24

24=2*3.142r

24=6.284r

r=24/6.284

r=3.8in

put r=3.6 in the expression for volume we have

V=4 /3π(3.8)^3

V=4 /3π(55

V=(220.59*3.142)/3

V=693.12/3

V=231in^3

The volume of the globe is 231in^3

The volume of the globe is 233  cubic inches.

Important information:

We need to find the volume of the globe.

Let [tex]r[/tex] be the radius of the globe.

Circumference of the globe along the equator is:

[tex]C=2\pi r[/tex]

[tex]24=2\pi r[/tex]

[tex]\dfrac{24}{2\pi }=r[/tex]

[tex]\dfrac{12}{\pi}=r[/tex]

Volume of the globe is:

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

[tex]V=\dfrac{4}{3}\pi \left(\dfrac{12}{\pi}\right)^3[/tex]

[tex]V=\dfrac{4}{3}\pi \left(\dfrac{1728}{\pi^3}\right)[/tex]

[tex]V=233.444...[/tex]

[tex]V\approx 233[/tex]

Therefore, the volume of the globe is 233  cubic inches.

Answer:

(0,10)

Step-by-step explanation:

All of  the other answers dont make sense or are false so it makes (0,10) the only correct answer.

The equation represents the situation is 5x + 2y ≤ 20 so pair (2,5) and (0,10) is possible thus options (A) and (B) is correct.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

As per the given,

Hardcover books cost $5 each and paperbacks cost $2 each.

The number of hardcover books is x while paperbacks are y

Thus,

Total cost = 5x + 2y

5x + 2y ≤ 20

The x and y is the whole number so they will never be negative or in fractions.

Therefore, The pair which satisfies the above expression is (2,5) and (0,10).

Hence "The equation represents the situation is 5x + 2y ≤ 20 so pair (2,5) and (0,10) is possible".
