Given:

Susan divides the fraction [tex]\dfrac{5}{8}[/tex] by [tex]\dfrac{1}{16}[/tex].

Her friend Robyn divides [tex]\dfrac{5}{8}[/tex] by [tex]\dfrac{1}{32}[/tex].

To find:

The quotient of Susan and Robyn.

Solution:

Susan divides the fraction [tex]\dfrac{5}{8}[/tex] by [tex]\dfrac{1}{16}[/tex].

[tex]\dfrac{\dfrac{5}{8}}{\dfrac{1}{16}}=\dfrac{5}{8}\times \dfrac{16}{1}[/tex]

[tex]\dfrac{\dfrac{5}{8}}{\dfrac{1}{16}}=\dfrac{80}{8}[/tex]

[tex]\dfrac{\dfrac{5}{8}}{\dfrac{1}{16}}=10[/tex]

So, Susan's quotient is 10.

Her friend Robyn divides [tex]\dfrac{5}{8}[/tex] by [tex]\dfrac{1}{32}[/tex].

[tex]\dfrac{\dfrac{5}{8}}{\dfrac{1}{32}}=\dfrac{5}{8}\times \dfrac{32}{1}[/tex]

[tex]\dfrac{\dfrac{5}{8}}{\dfrac{1}{32}}=5\times 4[/tex]

[tex]\dfrac{\dfrac{5}{8}}{\dfrac{1}{32}}=20[/tex]

So, Robyn's quotient is 20.

Since 20>10, therefore, Robyn will get greater quotient.

Step-by-step explanation:

3

When rounding off to the nearest whole number all you do is look at the first decimal and see if it is bigger than 5 which in this case it isn't so, the 3 stays the same and that would be your answer. If it was bigger than 5 then your whole number changes to 4.

Answer:

abosute value is the bigger number regardless of positives and negitives.

Step-by-step explanation:

Answer:

The absolute value of a number means the distance from 0. -7 is further from 0 than 6, therefore, it has a greater absolute value. Keep in mind, absolute value makes all numbers positive.

The dollar amount of shoes she sold is $1800

It is the amount earned on a product bought or sold.

If  she receives a commission of 11.5% for each pair of shoes she sells and earned $207, the amount earned is calculated using the formula:

11.5% of x = 207

0.115x = 207

Divide both sides by 0.115

x = 207/0.115

x = $1800

Hence the dollar amount of shoes she sold is $1800

Answer:

10km/hr

Step-by-step explanation:

Given that:

Distance covered by both Dee and Ron= 20km

Ron's speed = 8km/hr

Dee made three 10 minute stops during the race.

Time it took Ron to cover 20km

Time = distance / speed

20km / 8km/hr = 2.5 hours = 150 minutes

Since they both tied ;

Running time of Dee = (150 - (3*10)) = 120 minutes = 2 hours

Ron's speed = distance / time

Speed = 20 km / 2hours

Speed = 10km/hr

m = 36

Work

45 + 2.50m = 3.75m

Work Shown:

A = volume of the cylinder

A = pi*(radius)^2*(height)

A = pi*r^2*h

-----------

The cone's base has diameter r/2, so its radius is (1/2)*(r/2) = r/4

B = volume of the cone

B = (1/3)*(volume of cylinder with radius r/4 and height h)

B = (1/3)pi*(r/4)^2*h

B = (1/3)*pi*(r^2)/(4^2)*h

B = (1/3)*pi*(r^2)/16*h

B = (1/3)*(1/16)*pi*r^2*h

B = (1/48)pi*r^2*h

B = (1/48)*A

B = (1/48)*(volume of cylinder)

-----------

C = volume of the empty space/air inside cylinder, but outside cone

C = A-B

C = A - (1/48)*A

C = (48/48)A - (1/48)A

C = (48A)/48 - (A/48)

C = (48A-A)/48

C = 47A/48

C = (47/48)*A

C = (47/48)*pi*r^2*h

Answer:

The answer is below

Step-by-step explanation:

The two vectors together with the resultant vector forms a right angled triangle. The resultant vector R can be gotten using the formula:

R² = 12² + 5²

R² = 144 + 25

R² = 169

R = √169 = 13

R = 13 miles

The resultant vector is 13 miles

The direction is gotten from:

θ = tan⁻¹(5/12)

θ = 22.62° North West

The resultant vector is therefore 13 miles North West

Answer:

57 miles in 1 hr

Step-by-step explanation:

171/3 = 57

Answer:

x = 4

y = 1

Step-by-step explanation:

At first, let us find the third angle in the triangle which has a right angle and an acute angle of measure 52°

∵ The sum of the interior angles of a triangle is 180°

∴ 52° + 90° + (6x + 14y)° = 180°

→ Add the like terms

∴ 142° + (6x + 14y) = 180°

→ Subtract 142° from both sides

∴ (6x + 14y)° = 38° ⇒ (1)

→ By using the two triangles

∵ The two triangles are congruent

∴ (15x - 8y) = 52° ⇒ (2)

Now we have a system of equations to solve it

→ Multiply equation (1) by 5 and equation (2) by -2 to make the

   coefficients of x equal in values and different in signs

∵ 5(6x + 14y) = 5(38)

∴ 30x + 70y = 190 ⇒ (3)

∵ -2(15x - 8y) = -2(52)

∴ -30x + 16y = -104 ⇒ (4)

→ Add equations (3) and (4) to eliminate x

∵ 86y = 86

→ Divide both sides by 86 to find y

∴ y = 1

→ Substitute the value of y in equation (1) to find x

∵ 6x + 14(1) = 38

∴ 6x + 14 = 38

→ Subtract 14 from both sides

∴ 6x = 24

→ Divide both sides by 6

∴ x = 4
