Sophia can make 12 cakes and 4 loaves of bread.

The right answer is Option A.

Step-by-step explanation:

Given,

White flour used for one loaf of bread = 1/2 pound

White flour available = 2 pounds

Cake flour used to make one cake = 1/4 pound

Cake flour available = 3 pounds

We will divide the available amount by the amount used for one.

No. of loaves of bread = [tex]\frac{2}{\frac{1}{2}}=2*2[/tex]

No. of loaves of bread = 4

No. of cakes = [tex]\frac{3}{\frac{1}{4}}=3*4[/tex]

No. of cakes = 12

Therefore,

Sophia can make 12 cakes and 4 loaves of bread.

The right answer is Option A.

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

Volume of the sphere [tex]=\frac{4}{3} \pi r^{3}[/tex]

                                    [tex]$=\frac{4}{3} \times 3.14 \times(4.1)^{3}[/tex]

                                    [tex]$=\frac{4}{3} \times 3.14 \times68.921[/tex]

                                    = 288.55 cm³

The volume of the spherical piece is 288.55 cm³.

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.

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

Answer:

the width of the rectangle is 9 inches

the length of the rectangle is 15 inches

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

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:

415,000

Step-by-step explanation:

First, find the decimal equivalent of 125%. To do this, divide 125 by 100 or move two decimal places to the right: 125/100 = 1.25

Now multiply the amount of cars sold last year, 332,000, by the percentage decimal, 1.25: 332,000 x 1.25 = 415,000

The car manufacturer sold 415,000 cars this year

Her we know that Jacey wrote an equation to  find an angle measure. The equation is as follows:

[tex]\frac{360^{\circ}}{a}=b[/tex]

So, if the angle 360° is a central angle, that is, an angle between two radii in a circle, then:

a: Represents the number of equal parts parts the circle is divided

b: Represents the measure of the central angle of each part

For example, suppose you have a circle and want to divide it into six parts, then, the central angle of each part of the circle will measure 60 degrees as indicated in the figure below.

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

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.

x=3

Step-by-step explanation:

1. cross multiply to get

2. distribute

20x+10=35x-35

3. combine like terms

45=15x

4. divide :)

3=x

Answer:

x = 3

Step-by-step explanation:

(x - 1)/5 = (4x + 2)/35

to find the value of x

the first thing to do is to cross multiply

from this ,

(x-1)/5 = (4x + 2)/ 35

35(x-1) = 5( 4x + 2)

35x - 35 = 20x + 10

we are going to collect the like terms

35x -20x = 10 + 35

15x = 45

we are going to divide both sides by the coefficient of x which is 15

we have,

15x/15 = 45/15

x = 3

therefore the value of x = 3

to check if your answer is correct, put the value of x and slot it into one of the equations.

35x - 35 = 20x + 10

35(3) - 35 = 20(3) + 10

105 - 35 = 60 + 10
