Answer:

14g zinc

Step-by-step explanation:

To get the mass of zinc in the metal bar, you can multiply the percentage of zinc by the total mass.

40g x .35 = 14g zinc

The metal bar contains 14 g zinc in the 40 grams metal bar.

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here: A metal bar weighs 40 grams and it contains zinc equivalent to 35%

Let the weight of the zinc contained in the metal be x

Then we have x=35/100×40

                           =14 grams

Hence, The metal bar contains 14 g zinc in the 40 grams metal bar.

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:

75(5.76)=432

The standard deviation of Y is $432 and this can be determined by using the formula of standard deviation and the given data.

Given :

The formula to obtain the standard deviation is given below:

SD(Y) = SD(75X - 100)

Simplify the above expression by substituting the value of SD(X) and SD(100) in the above expression.

SD(Y) = 75SD(X) - SD(100)

SD(Y) = 75 SD(X) - 0

SD(Y) = 75 [tex]\times[/tex] 5.76

SD(Y) = $432

x=3

Step-by-step explanation:

1. cross multiply to get

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

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

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:

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.

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.
