Answer:

D

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{ST}{YZ}[/tex] = [tex]\frac{RS}{XY}[/tex] , substitute values

[tex]\frac{8}{16}[/tex] = [tex]\frac{2}{XY}[/tex] ( cross-  multiply )

8XY = 32 ( divide both sides by 8 )

XY = 4 feet → D

Answer:

a) 125.86 feet

b) 321.68 feet

c) 195.82 feet

Step-by-step explanation:

a)

To find the distance from the friend to the build, we just need to use the tangent relation of his angle. The opposite side is the height of the building and the adjacent side is his distance to the building:

tangent(50) = height / distance

1.1918 = 150 / distance

distance = 150 / 1.1918 = 125.86 feet

b)

Similarly to letter a), we can use the tangent relation of the zombie's angle, where the opposite side is the height of the building and the adjacent side is his distance to the building:

tangent(25) = height / distance

0.4663 = 150 / distance

distance = 150 / 0.4663 = 321.68 feet

c)

To find the distance from the zombie to the friend, we just need to subtract the two distances:

Distance = 321.68 - 125.86 = 195.82 feet

Answer:

Bryan can serve 6 bowls of blue berries

Step-by-step explanation:

Final answer:

Bryan can serve 6 bowls of blueberries and cream.

Explanation:

To calculate the number of bowls Bryan can serve, first determine how many bowls can be served from 3/4 of a bottle of cream. Since each bowl requires 1/8 of a bottle of cream, divide 3/4 by 1/8. This division is equivalent to multiplying 3/4 by the reciprocal of 1/8, which is 8/1. Thus, (3/4) / (1/8) = (3/4) * (8/1) = 6. Therefore, Bryan can serve 6 bowls of blueberries and cream with 3/4 of a bottle of cream. This calculation ensures efficient use of resources, allowing Bryan to accurately plan the quantity of ingredients needed for serving a specific number of bowls.

Final answer:

Megan's mistake is that she incorrectly stated that she gave 2/6 of the box of raisins to her friend, when in fact she gave 1/2 of the box of raisins.

Explanation:

Megan's mistake is that she incorrectly stated that she gave 2/6 of the box of raisins to her friend, when in fact she gave 1/2 of the box of raisins.

To understand Megan's mistake, let's calculate the amount of raisins she gave to her friend:

Megan has 5/6 of the box of raisins.

Giving 1/2 of those raisins to her friend means she is giving away (1/2) * (5/6) = 5/12 of the box of raisins.

So, Megan actually gave away 5/12 of the box of raisins to her friend, not 2/6 as she claimed.

Answer:

4.74; Explanation is as follows

Step-by-step explanation:

When you raise a number to a fractional power, it is the same as taking a root of that number. Here's what I mean:

We know that .8 is the same as 4/5, so 7^.8 power is the same as 7^4/5 power!

[tex]7^\frac{4}{5} =\sqrt[5]{7^4}[/tex]

The above equation is the same as 7 raised to the .8th power! Now to solve, we do the following:

[tex]=\sqrt[5]{7^4} \\=\sqrt[5]{7*7*7*7} \\= \sqrt[5]{2401} \\=4.74[/tex]

So that is how you raise 7 to the .8th power!

Answer:

5.4 laps

Step-by-step explanation:

One lap = 5/6 miles

= 0.833miles (approximately)

If 0.833 miles = 1 lap

4.5 miles = ?

4.5/0.833 = 5.4 laps

Final answer:

To find the number of laps the track team ran, divide the total distance by the length of each lap. In this case, the team ran approximately 5.4 laps.

Explanation:

To find the number of laps the track team ran, we need to divide the total distance they ran by the length of each lap. The total distance they ran is 4 1/2 miles, which can be written as 9/2 miles. Each lap is 5/6 miles long.

To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. So, to find the number of laps, we can multiply 9/2 by the reciprocal of 5/6: (9/2) x (6/5) = 54/10 = 5.4.

Therefore, the track team ran approximately 5.4 laps.

To calculate the length of CD, additional information about the geometric figure is necessary. Meanwhile, for operations like addition or subtraction, results should be rounded to the same number of decimal places as the number with the least decimal places.

The student's question seems to refer to the relationship between angles in a geometric figure and determining the length of a side, specifically the length of CD, within that figure. However, to provide a correct and precise length of CD, more information from the geometric figure or additional conditions are required, such as side lengths or other angle measurements. As the question stands, it lacks sufficient data to calculate the length of CD.

Regarding rounding, in general when you are performing mathematical operations like addition or subtraction, the result should be rounded to the same number of decimal places as the number with the least number of decimal places. For example, if you were to add 5.123 to 2.5, the result should be rounded to one decimal place, since 2.5 has only one decimal place. The correct sum would be 7.6.

To determine the amount of money saved when purchasing the desk on sale, you first need to find the original price of the desk before the discount.

Let's denote the original price of the desk as [tex]\( P \)[/tex].

Since the desk is on sale for 20% off, the sale price [tex]\( S \)[/tex] can be calculated as:

[tex]S=P-0.20\times P=0.80\times P[/tex]

Where:

- [tex]\( P - 0.20 \times P \)[/tex] represents the original price minus 20% of the original price.

-[tex]\( 0.80 \times P \)[/tex] represents 80% of the original price.

Now, to find the amount saved [tex](\( s \))[/tex], it's the difference between the original price [tex](\( P \))[/tex] and the sale price [tex](\( S \))[/tex]:

[tex]\[ s = P - S \][/tex]

Substituting the expression for [tex]\( S \)[/tex]:

[tex]\[ s = P - 0.80 \times P = 0.20 \times P \][/tex]

So, the equation that can be used to determine the amount of money saved, [tex]\( s \)[/tex], in dollars, when purchasing this desk on sale is:

[tex]\[ s = 0.20 \times P \][/tex]

Complete correct question:

A desk is on sale for $380, which is 20% off the original price. Which equation can be used to determine the

amount of money saved, s, in dollars, when purchasing this desk on sale?

A [tex]s= 0.2(380)[/tex]

B [tex]s= (380 = 0.8) - 380[/tex]

C [tex]s= (380 = 0.5) - 380[/tex]

D [tex]8 = (380 = 0.8)[/tex]

The equation that can be used to determine the amount of money saved when purchasing this desk on sale is:

[tex]\[ {\text{D) } s = (380 \times 0.8) - 380} \][/tex]

Hence the correct option is d.

To determine the amount of money saved (s) when purchasing the desk on sale, we need to calculate 20% of the original price.

The original price of the desk can be represented by x, and the sale price is $380.

We know that the sale price is 20% off the original price, so the equation representing the sale price is:

[tex]\[ \text{Sale price} = \text{Original price} - \text{Discount} \]\[ 380 = x - 0.2x \]\[ 380 = 0.8x \][/tex]

To find the amount saved, we subtract the sale price from the original price:

[tex]\[ s = x - 380 \]Now, let's solve for \( s \):\[ s = 0.8x - 380 \][/tex]

So, the equation that can be used to determine the amount of money saved when purchasing this desk on sale is:

[tex]\[ {\text{D) } s = (380 \times 0.8) - 380} \][/tex]

Hence the correct option is d.

The question asks about the geometrical properties of two scarves, one square and one rectangular. The area of the square scarf is 1024 square inches and that of the rectangular one is 960 square inches. Additionally, the square scarf has a side length of 32 inches and the rectangular scarf has lengths of 48 and 20 inches.

The subject of the question being asked is Mathematics. Specifically, it deals with the concepts of area and perimeter for square and rectangular shapes. For the square scarf, since all sides are equal and each one is 32 inches, we calculate its area by squaring one side (32*32), yielding an area of 1024 square inches. Its perimeter (the total length of the boundary) is 4*32 i.e., 128 inches.

For the rectangular scarf, its area is determined by the formula length*width, so 48*20 equals 960 square inches. Its perimeter is the sum of all sides (2*length + 2*width) equates to 2*48+2*20 = 136 inches.

Therefore, looking at the given options, the statement regarding both the area and the length of a side (option d) is correct, as we computed the area and side length for both scarves, along with the incorrect calculations provided.

Answer:

An independent variable is a variable or value that is changed, altered, or entered, while a dependent variable is a variable or value that is being observed.

Step-by-step explanation:

Hoped this helped

Answer:

An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.

dependent variable is the variable being tested and measured in a scientific experiment.

The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.

Independent and Dependent Variable Example

For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source) would be the dependent variable.

How to Tell the Variables Apart

The independent and dependent variables may be viewed in terms of cause and effect. If the independent variable is changed, then an effect is seen in the dependent variable. Remember, the values of both variables may change in an experiment and are recorded. The difference is that the value of the independent variable is controlled by the experimenter, while the value of the dependent variable only changes in response to the independent variable

Answer:

2 Movements

Step-by-step explanation:

Let us name the tokens

B-For Black Tokens

W-For White Tokens

The initial arrangement is therefore given as:

B-B-B-B-W-W-W-W-W

Since we are allowed to flip three tiles in each turn

First movement: Flip two blacks and one white, we would have:

B-B-W-W-W-W-W-W-B

Second movement: Flip the three black tokens, this would give us:

W-W-W-W-W-W-W-W-W

Therefore, the least number of movements to have all tokens showing the same color is 2.

Answer:

A) 3x + 2y = 12

B) 6x + 3y = 21

We multiply A) by -2

A) -6x -4y = -24  then we add B)

B) 6x + 3y = 21

-y = -3

y = 3

Since y = 3 then

x = 2

Step-by-step explanation:

Answer:

( −2)⋅( 3x +2y )= (−2)(12)(-2)⋅(3x+2y)= (-2)(12)

6x+3y=21

Step-by-step explanation:

Multiply each equation by the value that makes the coefficients of x opposite.

Simplify ( -2) ⋅(3x+2y)(-2)⋅(3x+2y)

Apply the distributive property.

−2(3x) − 2 (2y)=(−2) (12)

6x+3y=21

Multiply 3 by -2.

−6x − 2(2y)= (2)(12)

6x+3y=21

Multiply 2 by -2

−6x −4y = (−2)(12)

6x+3y=21

Multiply -2 by 12

−6x−4   y=−24

X  6x+3 y=21

          -y = -3

Multiply each term in -y = -3 by -1.

(-y) ⋅ -1 = (-3) ⋅ -1

Multiply -1 by -1

1y = (-3) ⋅ -1

Multiply y by 1

y= (-3) ⋅ - 1

Multiply -3 by -1

y= 3

Substitute the value found for y into one of the original equations, then solve for x.

−6x −4⋅3=−24

Multiply −4 by 3.

−6x−12=−24

Move all terms not containing x to the right side of the equation.

Add 12 to both sides of the equation.

−6x = −24+12

Add −24 and 12.

−6x=−12

Divide each term by −6 and simplify.

Divide each term in  −6x = −12 by −6.

-6x     =       -12  

-6        =        -6      

Cancel the common factor of −6.

Divide x by 1.

         −12

x=      -6

Divide −12 by −6.

x=2

The solution to the independent system of equations can be represented as a point.
