Answer:

Equation : [tex]\frac{2}{5}r=8[/tex]

She can make 20 bows with 8 yards of ribbon

Step-by-step explanation:

Gloria needs 2/5 yard of ribbons to make each bow.

Length of 1 bow =[tex]\frac{2}{5} yards[/tex]

Let r be the no. of bows made

So, Length of r bows = [tex]\frac{2}{5}r[/tex]

We are given that  she can make r bows with 8 yards of ribbon

So, Equation : [tex]\frac{2}{5}r=8[/tex]

[tex]r=\frac{8 \times 5}{2}[/tex]

r=20

Hence She can make 20 bows with 8 yards of ribbon

A polynomial's degree is the highest total exponent in the polynomial.

Example: 5xy^2 has a degree of 3.

x has a exponent of 1 and y had a exponent of 2 so in total it is 3.

Answer: 2144.7 cm^3

Step-by-step explanation: You need to find the volume of a sphere with a radius of 8 cm if you want to know how much water Jack can hold.

V = 4/3 π r^3 = 4/3 * π * 8^3 ≈ 2144.7 cm^3

Answer: y = 2

Explanation: When the equation of any line reads y = a number, its graph will always be a horizontal line.

So, y = 2 would be a horizontal or flat line.

Answer:

all real numbers.

Step-by-step explanation:

First, distribute 3 to all terms within the parenthesis:

3(x + 4) = 3(x) + 3(4) = 3x + 12

3x + 12 = 3x + 12

Because both sides are the same, your answer for x is "all real numbers".

Answer:

[tex]9 \dfrac12 m^2[/tex]

Step-by-step explanation:

Tanya has a garden with a trench around it.

Tanya's garden is a rectangle with length [tex]\dfrac12 \text{m}[/tex] and width 2m.

The trench and garden together make a rectangle with length [tex]3 \dfrac12 \text{m}[/tex] and width 3m.

We are to determine the area of just the trench.

Area of just the trench = Area of the trench and garden together-Area of the garden

[tex]=(3 \dfrac12 X 3)-(\dfrac12 X 2)\\\\=( \dfrac72 X 3)-1\\\\=\dfrac{21}{2}-1\\\\=9 \dfrac12 m^2[/tex]

The area of the trench is [tex]9 \dfrac12 m^2[/tex]

Step-by-step explanation:

In the graph, the altitude represents Y axis while time represents the X axis. we can see that at interval 1 the function is dramatically decreasing. At Interval 2 the function is constant. At interval 3 the function is increasing but I can't say definitively if the slope is positive or negative. Hope this helped!

Answer:

The equation of the parabola is:

[tex]x = 12\cdot m \cdot y^{2}[/tex]

Step-by-step explanation:

The equation of the parabola is:

[tex]x = 4\cdot p \cdot y^{2}[/tex]

Where [tex]p[/tex] is equal to the distance between focus and vertex. Then,

[tex]p = 3\cdot m[/tex]

Lastly, the equation of the parabola is:

[tex]x = 12\cdot m \cdot y^{2}[/tex]

Answer: x = (1/12m)(y^2)

Step-by-step explanation:

Focus at (3m, 0)

Directrix equation, x = -3m

Distance from focus = distance from directrix

√(x-3m)^2 + (y-0)^2 = √(x - (-3m))^2 + (y -y)^2

(x - 3m)^2 + y^2 = (x + 3m)^2

y^2 = (x + 3m)^2 - (x - 3m)^2

y^2 = x^2 + 6mx + 9m^2 - x^2 +6mx - 9m^2

Collecting like terms and simplifying

y^2 = 6mx + 6mx

y^2 = 12mx

x = (1/12m)(y^2)

Quick question: Is this a multiple choice question and if so, may you provide the multiple choice answers before I give you a proper answer?

Answer:

(3.5, -2)

Step-by-step explanation:

Just got it right on edge 2020

The solution to the system of linear equations is: (3.5, -2).

Thus, having solve for y as -2, substitute y = -2 into 12x – 21y = 84.

12x – 21(-2) = 84

12x + 42 = 84

12x = 84 - 42

12x = 42

x = 3.5.

Therefore, the solution to the system of linear equations is: (3.5, -2).

Answer:

The total surface area is 90π cm²

Step-by-step explanation:

To find the total surface area of his cone, we will follow the steps below;

write the formula for finding the total surface area of a cone

Total surface area = πrl + πr²

where r is the radius  and l is the slant height

from the question, diameter = 10 cm, diameter = 2r     this implies  that r = d/2 = 10/2 = 5 cm

Also from the question given to us, height h = 12 cm, but what we want  is slant height l. We can find this by using the Pythagoras theorem to find the slant height using the height giving to us and the radius.

opposite² + adjacent² = hypotenuse²

where radius is the adjacent, height is the opposite  and the slant height is the hypotenuse

5²  +  12²  = l²

25 + 144 = l²

169 = l²

13 = l

l= 13 cm

hence slant height =13 cm

We can now proceed to insert the values into the formula

Total surface area = πrl + πr²

                              = π×5×13 + π×5²

                               =65π + 25π

                                =90π cm²

The total surface area is 90π cm²

Answer: Triangular = 600

Rectangular = 300

Hexagonal = 100

Step-by-step explanation:

Given Data:

Shapes of fabric used

Hexagonal = 1

Rectangular = 3

Triangular = 6

Total quantity of fabric = 1000 pcs

Solution

How many pieces of each does she use.

1 + 3 + 6 = 10

Hexagonal = 1/10

Rectangular = 3/10

Triangular = 6/10

Quantity of hexagonal used

= 1/10 * 1000

= 100 pieces

Quantity of rectangular used

= 3/100 * 1000

= 300 pieces

Quantity of triangular used

= 6/10 * 1000

= 600 pieces

Therefore

Triangular = 600

Rectangular = 300

Hexagonal = 100

Answer: 7/24

Step-by-step explanation: Think of the 2 as 2/1.

When dividing by a fraction, we can simply change, we can simply change the multiplication sig to division and take the reciprocal of the second fraction or flip the second fraction.

So our problem can be rewritten as [tex](\frac{7}{12})[/tex] [tex]x[/tex] [tex](\frac{1}{2})[/tex].

Answer:

y = -2 +sqrt(7)

y = -2  - sqrt(7)

Step-by-step explanation:

y^2 +4y +4 = 7

Factor, recognizing that this is the sum of squares

a^2 +2ab+b^2 = (a+b)^2

(y+2) ^2 = 7

Take the square root of each side

sqrt((y+2) ^2) =± sqrt(7)

y+2 = ± sqrt(7)

Subtract 2 from each side

y+2-2 = -2  ± sqrt(7)

y = -2  ± sqrt(7)

Answer: 6 minutes

Step-by-step explanation:

From the question, Toy train A crosses a pole after every 24seconds while Toy train B crosses the pole after every 30 seconds and then toy train C crosses the pole after every 36 seconds. We are going to solve this by finding their lowest common multiple (LCM).

24 = 24, 48, 72, 96, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360.

30 = 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 360, 390

36 = 36, 72, 108, 144, 180, 216, 252, 288, 324, 360.

We can see that the lowest common multiple of 24, 30 and 36 is 360.

Since 60 seconds make 1 minute, this will be converted to minutes.

= 360/60

= 6 minutes.

They all cross the pole together after 6 minutes.

Answer: 1.72 kilograms

Step-by-step explanation:

From the question, Ricardo is making a container of trail mix with 3.5 kilograms of nuts and he has 1.78 kilograms of almonds while the remaining of the nuts will be cashews.

To get the kilograms of cashews nuts that are needed, we subtract the kilograms of almonds from the total container. This will be:

= 3.5 kg - 1.78 kg

= 1. 72 kg
