The figure is the net for a rectangular prism.

What is the surface area of the rectangular prism represented by the net?

The distance between the two lines,-2x + y = 6 and x = 1/2x - 4, is approximately 4.5 units

To find the distance between two lines, we can use the formula:

Distance = |(Ax + By + C)| / sqrt(A^2 + B^2)

Where A, B, and C are the coefficients of the standard form equation of the first line

and x and y are the coordinates of a point on the second line.

Let's first convert the equations of the lines into the standard form (Ax + By + C = 0):

-2x + y - 6 = 0 --> 2x - y + 6 = 0 (Line 1)

x - 2x/2 - 4 = 0 --> -x + 4 = 0 --> x - 4 = 0 (Line 2)

Now, we can use the formula to find the distance between the two lines:

distance = |(Ax + By + C)| / sqrt(A^2 + B^2)

Let's take a point on Line 2, for example, (4,0). Then:

Distance = |(24 - 10 + 6)| / sqrt(2^2 + (-1)^2)

Distance = |10| / sqrt(4 + 1)

Distance = 10 / sqrt(5)

Distance = 4.472

Distance ≈ 4.5

Hence, the distance is approximately 4.5 units

EF is 1.98, AB is 16.23 and HI is 12.22

Step-by-step explanation:

Step 1:

In figure 1, given sin 26° = 0.44 and hypotenuse = 4.5. Use trigonometric ratio sin D to find EF.

sin 26° = EF/DF

⇒ 0.44 = EF/4.5

∴ EF = 0.44 × 4.5 = 1.98

Step 2:

In figure 2, given cos 52° = 0.616 and adjacent side (AC) = 10. Use trigonometric ratio cos A to find hypotenuse (AB).

cos 52° = AC/AB

⇒ 0.616 = 10/AB

∴ AB = 10/0.616 = 16.23

Step 3:

In figure 3, given tan 42° = 0.90 and opposite side (GH) = 11. Use trigonometric ratio tan I to find adjacent side (HI).

tan 42° = GH/HI

⇒ 0.90 = 11/HI

∴ HI = 11/0.90 = 12.22

Answer:

1) 1.98 units

2) 16.23 units

3) 12.22 units

Step-by-step explanation:

Q1) sin(26) = EF/ FD

0.44 = EF/4.5

EF = 4.5×0.44 = 1.98

Q2) cos(52) = AC/AB

0.616 = 10/AB

AB = 10/0.616

AB = 16.23

Q3) tan(42) = GH/HI

0.9 = 11/HI

HI = 11/0.9

HI = 12.22

760 sq feet

Step-by-step explanation:

Step 1 :

The sides of the given parallelogram are 60 feet and 40 feet and the height is 38 feet

The length of the rectangular walkway = 38 ft

Width of the walkway = 20 ft

The roses are planted in the park (parallelogram) except in the walkways 's area ( rectangle)

Hence the total area where the roses are planted is the park 's area (parallelogram) - the walkway's area ( rectangle.)

Step 2 :

Area of the park (parallelogram ) = b * h = 40 * 38 = 1520 sq ft

Area of the walkway (rectangle) = l * b = 38 * 20 = 760 sq ft

Area of the park where roses will be planted = 1520 - 760 = 760 sq ft.

Answer: b is -48

Step-by-step explanation:

-21 = b/3 - 5/1

Cross multiply

b-15= -21 ×3

b-15= -63

b= -63 + 15

b= -48

To cross -check,

Answer:

12 pints is bigger

Explanation: A pint is two cups, so 12 pints would be 24 cups.

The correct answer is that 12 pints is bigger than 6 cups.

To understand why, let's look at the conversion factors between pints and cups. In the United States Customary System, 1 pint is equivalent to 2 cups.

Now, let's calculate the volume of 12 pints in cups:

[tex]\[ 12 \text{ pints} \times \frac{2 \text{ cups}}{1 \text{ pint}} = 24 \text{ cups} \][/tex]

Comparing 24 cups (which is the equivalent of 12 pints) to 6 cups, it is clear that 24 cups is larger than 6 cups. Therefore, 12 pints is bigger than 6 cups.

Answer:

The winner play 341 games.

Step-by-step explanation:

An online video game tournament begins with 1024 players.

Four players play in each  game

It forms GP : [tex]\frac{1024}{4}=256 , \frac{256}{4}=64 , \fra{64}{4}=16 , \frac{16}{4}=4 , \frac{4}{4}=1[/tex]

So, GP: 256, 64,16,4 , 1

First term = a = 256

Common ratio = [tex]\frac{64}{256}=\frac{4}{16}=\frac{1}{4}[/tex]

Formula of nth term =[tex]a_n=ar^{n-1}[/tex]

[tex]1 = 256 (\frac{1}{4})^{n-1}[/tex]

[tex]\frac{1}{256}=(\frac{1}{4})^{n-1}[/tex]

[tex](\frac{1}{4})^9=(\frac{1}{4})^{n-1}[/tex]

4=n-1

5=n

So, Sum of first n terms=[tex]S_n=\frac{a(1-r^n)}{1-r}[/tex]

Substitute n = 5

[tex]S_5=\frac{256(1-(\frac{1}{4})^5)}{1-\frac{1}{4}}[/tex]

[tex]S_5=341[/tex]

Hence the winner play 341 games.

The winner will play 10 games.

With 1024 players for the first round, each game will have 4 players. Since there can only be one winner per game, the winner of each game will advance to the next round. To determine the number of games the winner will play, we need to find out how many rounds there will be. In each round, the number of players is halved until only one player remains. Therefore, the number of rounds is equal to the logarithm base 2 of the initial number of players. So, the winner will play a total of log2(1024) = 10 games.

Step-by-step explanation:

He should use 886 fluid ounces of soap.

Step-by-step explanation:

Know that 8 fluid ounces make 1 cup.

Now 24 cups need 32 fluid ounces or, 3 fluid ounces of water need 32 fluid ounces of soap.

Thus, by unitary method,

84 ounces of water need 32 × 84 / 3 ounces of soap.

Thus the answer comes to 886 ounces.

Answer:

Height of flagpole = 571 ft

Step-by-step explanation:

Given:

Angle of elevation to the top of the flagpole is 55° .

Distance from the eyes to the base of flagpole = 400 ft.

To find the height of the flagpole.

Solution:

We can draw the situation as a right triangle as shown below.

In triangle ABC.

[tex]BC=400\ ft[/tex]

∠C= 55°

To find the length AB (height of the flagpole).

Applying trigonometric ratio :

[tex]\tan\theta=\frac{Opposite\ side}{Adjacent\ side}[/tex]

[tex]\tan C=\frac{AB}{BC}[/tex]

Plugging in values.

[tex]\tan 55\°=\frac{AB}{400}[/tex]

Multiplying both sides by 400.

[tex]400\tan 55\°=\frac{AB}{400}\times 400[/tex]

[tex]571.26=AB[/tex]

∴ [tex]AB\approx 571\ ft[/tex]

Height of flagpole = 571 ft

Final answer:

The flagpole's height is approximately 571 feet when rounded to the nearest foot.

Explanation:

To find the height of the flagpole, we use the angle of elevation and the distance from the observer to the flagpole's base, which forms a right-angled triangle. We can calculate the height of the flagpole by using the tangent function:

Tan(55°) = (height of the flagpole) / 400 ft

Therefore,

(height of the flagpole) = tan(55°) * 400 ft

A calculator can be used to find that tan(55°) approximately equals 1.4281.

Multiplying this by 400 gives the height of the flagpole:

Height of the flagpole = 1.4281 * 400 ft

Height of the flagpole ≈ 571.24 ft

When rounded to the nearest foot, the height of the flagpole is approximately 571 feet.

The volume of the spherical piece is 288.55 cm³.

Solution:

Diameter of the sphere = 8.2 cm

Radius of the sphere = 8.2 ÷ 2 = 4.1 cm

The value of π = 3.14

Step-by-step explanation:

For this case we have that by definition, the perimeter of the rectangle is given by:

[tex]P = 2w + 2L[/tex]

Where:

W: Is the width of the rectangle

L: is the length of the rectangle

According to the data we have:

[tex]L = 6 + w\\P = 48[/tex]

Substituting:

[tex]48 = 2w + 2 (6 + w)\\48 = 2w + 12 + 2w\\48 = 4w + 12\\48-12 = 4w\\36 = 4w\\w = \frac {36} {4}\\w = 9[/tex]

So, the width of the rectangle is 9 inches

[tex]L = 6 + 9 = 15[/tex]

So, the length of the rectangle is 15 inches

the width of the rectangle is 9 inches

the length of the rectangle is 15 inches

Sorry mam I use mental math

Answer: X = —5 and Y = —2

Step-by-step explanation: What we have is a pair of simultaneous equations;

3X + Y = —17 —————-(1)

6X — 6Y = —18 ————(2)

We shall use the substitution method as instructed. Looking at equation (1),

We shall make Y the subject of the equation, hence

Y = —17 —3X

We shall now substitute for the value of Y into equation (2)

6X — 6Y = —18

6X — 6(—17 —3X) = —18

6X + 102 + 18X = —18

By collecting like terms we now have

24X = —18 —102

(Note that when a positive value crosses to the other side of the equation it becomes negative and vice versa)

24X = —120

Divide both sides of the equation by 24

X = —5

Having calculated the value of X as —5, we can now calculate Y as follows

From equation (1)

3X + Y = —17

3(—5) + Y = —17

—15 + Y = —17

Add 15 to both sides of the equation

—15 + 15 + Y = —17 + 15

Y = —2

Therefore, X = —5 and Y = —2
