Answer:

r = - [tex]\frac{12}{7}[/tex]

Step-by-step explanation:

Given that r varies inversely as t , then the equation relating them is

r = [tex]\frac{k}{t}[/tex] ← k is the constant of variation

To find k use the condition t = - 6 when r = - 2, then

- 2 = [tex]\frac{k}{-6}[/tex] ( multiply both sides by - 6 )

12 = k, thus

r = [tex]\frac{12}{t}[/tex] ← equation of variation

when t = - 7, then

r = [tex]\frac{12}{-7}[/tex] = - [tex]\frac{12}{7}[/tex]

Answer:

The length of the rectangle is x+5.

Step-by-step explanation:

Given : The rectangle below has an area of [tex]x^2+8x+15[/tex] square meter and a width of  [tex]x+3[/tex] meter.

To find : What expression represents the length of the rectangle?

Solution :

The area of the rectangle is given by,

[tex]\text{Area}=\text{Length}\times \text{Breadth}[/tex]

[tex]\text{Area}=x^2+8x+15[/tex]

[tex]\text{Breadth}=x+3[/tex]

[tex]x^2+8x+15=\text{Length}\times(x+3)[/tex]

[tex]\text{Length}=\frac{x^2+8x+15}{x+3}[/tex]

[tex]\text{Length}=\frac{(x+5)(x+3)}{x+3}[/tex]

[tex]\text{Length}=x+5[/tex]

Therefore, the length of the rectangle is x+5.

Final answer:

The length of the rectangle is found by dividing the area (x² + 8x + 15) by the width (x + 3), which simplifies to x + 5 meters, as the (x + 3) factor cancels out.

Explanation:

To find the length of the rectangle, we can use the area formula for rectangles, which is area = length × width.

According to the question, the area of the rectangle is given by the quadratic expression x² + 8x + 15, and the width is given by x + 3. To find the length, we divide the area by the width:

length = ²/(x + 3)

² + 8x + 15 is factorable, and its factors are (x + 5)(x + 3), which simplifies to:

length = (x + 5)(x + 3)/(x + 3)

When the polynomial is factored, we can see that the (x + 3) terms cancel each other out:

length = x + 5

So, the expression representing the length of the rectangle is x + 5 meters. It is important to note that when dealing with units, one must ensure they are consistent. However, there is no need for conversion here since the area and width are already in terms of meters and square meters respectively.

To find the number of golf balls that can fit in the compartment, we calculate the volume of the compartment and then divide by the volume required to pack a golf ball. We can fit around 88 golf balls in the bag.

We first need to find the volume of the rectangular prism. The volume of a rectangular prism can be found by multiplying the length, width, and height. So, volume = 6 * 8 * 9 = 432 cubic inches.

Next, we can find the volume of a golf ball which is a sphere using the formula 4/3 * π * r³ where r is the radius of the sphere. The diameter of the golf ball is given as 1.7 inches, which means the radius is 1.7/2 = 0.85 inches. So, the volume of the golf ball = 4/3 * π * (0.85)^3 = 2.57 cubic inches (approx).

As per the question, in a random packing of spheres, 190% of the volume of the sphere is needed. Therefore, the required volume for each ball = 2.57 * 190/100 = 4.87 cubic inches. The total number of balls that will fit = volume of rectangle/volume of each ball = 432/4.87 = 88 (rounded down to a whole number). So, the answer is 88 balls.

Step-by-step explanation:

Both of these represent 2 terms x 2 terms, so that means they are both in factored form.

Example:

Answer:

10. Perimeter = 56 ft  ;  Area = 195 sq. ft.

11. If my math is correct, Perimeter = 76 km  ;  Area = 706 sq. km

12. Circumference = 100[tex]\pi[/tex] cm  ;  Area = 2500[tex]\pi[/tex] sq. cm

13. Circumference = 24[tex]\pi[/tex] ft.  ;  Area = 144[tex]\pi[/tex] sq. ft.

14. Perimeter = 62 ft.  ;  Area = 238 sq. ft.

15. Circumference = 22[tex]\pi[/tex] yd.  ;  Area = 121[tex]\pi[/tex] sq. yd.

16. Perimeter = 40 mm  ;  Area = 100 sq mm

We need to get the radius.  We are given the diameter

r = d/2 = 14/2 =7

A = pi (7)^2

A =49pi

Using 3.14 for pi

A = 49 (3.14)

A =153.86 yd^2

Answer:

1:7

Step-by-step explanation:

R = RED | B = BLUE | P = PINK | BL = BLACK | c = chips

10R + 10B + 12P = 32 chips

40c - 32c = 8 black chips

8BL - 3BL = 5 black chips

10R - 2R = 8 red chips

2R + 3BL = 5 chips

40c - 5c = 35 chips

5BL : 35c = 1:7

The probability that next one Susan removes is black chips is 1/7.

The probability is defined as the possibility of an event is equal to the ratio of the number of outcomes and the total number of outcomes.

Total no. of chips = 40

No. of red chips = 10

No. of blue chips = 10

No. of pink chips = 12

No. of black chips = 8

If Susan were to remove 3 black and 2 red chips

So, No. of available black chips = 8 -3 = 5

No. of available red chips = 10 - 2 = 8

Total removed chips = 5

Total no. available of chips = 35

The probability that next one Susan removes is black chips = 5/35 = 1/7

Hence, the probability that next one Susan removes is black chips is 1/7.

Answer:

It ends between 13cm and 14cm mark.

Step-by-step explanation:

Since this marker in question is almost 14 centimeters long and definitely ends between two centimeter marks, the two centimeters that the length of this marker ends between on a ruler should be the 13cm and 14cm marks on the ruler.

Final answer:

The length of a marker almost 14 centimeters long ends between the 13 centimeter-mark and the 14 centimeter-mark on a ruler.

Explanation:

When measuring a marker that is almost 14 centimeters long, we look at the ruler and identify the two consecutive centimeter marks between which the length of the marker falls. If the marker is almost 14 centimeters long, this means it is greater than 13 centimeters but less than 14 centimeters.

Therefore, we can confidently say that the marker's length lies between the 13 centimeter-mark and the 14 centimeter-mark on the ruler. The smaller centimeter-mark would be 13, as it is the immediately preceding whole centimeter before the marker ends.

x = [tex]\frac{-3+\sqrt{19} }{2}[/tex] or x = [tex]\frac{-3-\sqrt{19} }{2}[/tex]

Step-by-step explanation:

We want to factor this. In order to factor it, we need to use the quadratic formula:

[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] or [tex]x=\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]

Graphing an inequality involves drawing a number line, marking the critical value, here -5, with an open circle because it's not included in the solution, and indicate with an arrow every number greater than -5, as these are the solutions to the inequality.

To graph m > -5 on a number line, you first need to draw a straight line, representing the number line. Mark -5 on the line. Since the inequality is 'greater than' (-5), you will have an open circle at -5. The open circle indicates that -5 is not included in the solution. The solutions for the inequality are all values to the right of -5, so you would draw an arrow pointing towards the right from the open circle. This demonstrates that all numbers greater than -5 are the solution to the inequality.
