Answer: 30%

Step-by-step explanation:

Subtract the original cost from the on sale price.

21.50 - 15.05 = 6.45

Divide the savings by the original cost.

6.45/21.50 = .3

Multiply by 100

.3 * 100 = 30

Answer:

30% percent

Step-by-step explanation:

21.50-15.05=6.45

21.50÷6.45=3.

3×100=30%

we times 100 because 1 equal 100%.So you need to do is just to multiply the number by 100 and add at the end symbol %

Answer: Elizabeth and Manuel have a distance of 4 meters between them.

Step-by-step explanation: Please refer to the picture attached.

From the information given, Elizabeth is directly behind Hannah and directly left of Manuel. That means we have three points which are HEM, that is, we now have triangle HEM. The longest side (hypotenuse) which is the distance between Hannah and Manuel is given as 5 meters while the other side the distance between Hannah and Elizabeth is given as 3 meters.

We shall apply the pythagoras theorem in solving for the unknown side, EM.

The Pythagoras theorem states thus;

AC² = AB² + BC²

Where AC is the hypotenuse, and AB and BC are the other two sides.

Substituting for the known values, we now have;

5² = 3² + EM²

25 = 9 + EM²

Subtract 9 from both sides of the equation

16 = EM²

Add the square root sign to both sides of the equation

√16 = √EM²

4 = EM

Therefore the distance between Elizabeth and Manuel is 4 meters

Final answer:

To calculate the distance between Elizabeth and Manuel, the Pythagorean theorem is used. Given the 3-meter distance between Hannah and Elizabeth, and the 5-meter distance between Hannah and Manuel, the distance between Elizabeth and Manuel is calculated to be the square root of 34, which is approximately 5.83 meters.

Explanation:

The question pertains to finding the distance between Elizabeth and Manuel, given their respective positions on a stage in relation to Hannah.

To find the distance between Elizabeth and Manuel, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Here, the distances between Hannah and the other two dancers form two sides of a right-angled triangle with Elizabeth and Manuel's positions marking the ends of the hypotenuse.

Since Hannah is 3 meters from Elizabeth and 5 meters from Manuel, we can calculate the distance between Elizabeth and Manuel (hypotenuse) with the following equation:
c^2 = a^2 + b^2

Where c is the distance between Elizabeth and Manuel, a is the distance between Hannah and Elizabeth (3 meters), and b is the distance between Hannah and Manuel (5 meters).

So, c^2 = 3^2 + 5^2 which simplifies to c^2 = 9 + 25, and further to c^2 = 34. This implies that c = [tex]\sqrt{34}[/tex].

Therefore, the distance between Elizabeth and Manuel is the square root of 34, which is approximately 5.83 meters. We can round this to the nearest hundredth for a precise measurement.

The distance between Elizabeth and Manuel is approximately 5.83 meters.

The total number of combinations is 2000. Testing each one at a rate of 10 seconds per test would take approximately 20,000 seconds, which is around 6 hours when rounded to the nearest hour.

This problem deals with the concept of combinations in mathematics. To find out how long it would take to try all possible combinations, you first need to determine how many combinations there are. The door code consists of either A or B (2 options) followed by a three-digit code (10 options for each digit, from 0-9). Therefore, there are 2 * 10 * 10 * 10 = 2000 possible combinations. If each combination takes 10 seconds to try, it would take 2000 * 10 = 20,000 seconds. To convert this to hours, divide by 3600 (as there are 3600 seconds in one hour), rounding to the nearest whole number, would give approximately 6 hours.

The equation representing 'twenty less than the product of 3 and a number is -29' is 3n - 20 = -29. Solving for n, we find that n equals -3.

When solving the equation twenty less than the product of 3 and a number is -29, we can translate this into a mathematical expression as 3n - 20 = -29, where n represents the unknown number. To find the value of n, add 20 to both sides of the equation, which gives us 3n = -9. Dividing both sides by 3, we find that n = -3. Thus, the number we are looking for is -3.

[tex]116.5^{3}[/tex]

The approximate total volume of the silo is 116.9 m^3, the correct option is C. 116.5 m^3.

Suppose that the radius of considered right circular cylinder be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

Right circular cylinder is the cylinder in which the line joining center of top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.

We are given that;

Diameter=4.4m

Height=6.2meter

Now,

The radius of the silo is half of its diameter, which is 4.4/2 = 2.2 meters. So, plugging in the given values and using 3.14 for π, we get:

V = πr^2h + (2/3)πr^3

V = 3.14(2.2^2)(6.2) + (2/3)3.14(2.2^3)

V = 94.25 + 22.64

V = 116.89

Therefore, the volume of silo will be 116.5 m^3.

The range of the function y=|x-1|+7 is all real numbers greater than or equal to 7, as the absolute value ensures non-negative values to which 7 is added.

The range of the function y=|x-1|+7 can be determined by analyzing the nature of the absolute value function and the constant term. The absolute value function, |x-1|, ensures that the output is always non-negative for any value of x, since it represents the distance from 1 on the number line, which cannot be negative. Therefore, when we add 7 to this non-negative value, the smallest value y can take is when |x-1|=0, which is when x=1. So, at x=1, y will be 7 since we have 0+7. For any other value of x, |x-1| will be positive, and when adding 7, y will be greater than 7. Hence, the range of y is all values greater than or equal to 7.

A randomly chosen quadrilateral has four right angles, has a probability that the quadrilateral also has four equal side lengths is 33%.

Probability is a measure of the likelihood of an event to occur.

Many events cannot be predicted with total certainty.

We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.

Given is a Venn diagram,

In the Venn diagram, we can see that we have 9 elements, 6 of these belong to the set R, 3 of them belong to the set E, and 2 belong to both sets.

Now we want to find the probability that, if a figure has four right angles (belongs to R) it also has 4 equal side lengths (belongs to E).

So, given that an element belongs to R (6 elements there).

The probability that it also belongs to E,

2 out of these 6 elements belong to E, so the probability will be:

P = 2/6 = 1/3 = 0.33

To get this in percent form, we need to multiply it by 100%, we will get:

0.33x100% = 33%

Answer:

42.5

Step-by-step explanation:

so you start with adding 15 to the equations because that is how many days

1.5 15 +20

1.5 x 15 =22.5

22.5+20=42.5

so 42.5 is the answer

The predicted height of the plant 15 days from today is 42.5 cm.

The given expression for the height of a plant is 1.5t + 20, where t represents the number of days from today. To find the predicted height of the plant 15 days from today, we need to substitute t = 15 into the expression.

        height of the plant 15 days from today = 1.5(15)+20 cm

        height of the plant 15 days from today = 22.5 + 20 cm = 42.5 cm

Therefore, the predicted height of the plant 15 days from today is 42.5 cm.

For equilateral triangle, length of both sides are equal hence 18y-41=3x+1=49

Solving for x

Given that 3x+1=49

Rearranging like terms

3x=49-1=48

x=48/3=16 units

Solving for y

Considering that 18y-41=49

18y=49+41=90

y=90/18=5 units

The value of x = 16 and y = 5.

Given that [tex]\( \triangle ABC \)[/tex] is an equilateral triangle, all sides are equal. Therefore, we have:

[tex]\[ AB = BC = AC \][/tex]

Given the side lengths:

[tex]\( AB = 49 \)[/tex] meters

[tex]\( BC = 3x + 1 \)[/tex] meters

[tex]\( AC = 18y - 41 \)[/tex] meters

Since [tex]\( AB = BC \)[/tex]:

[tex]\[ 49 = 3x + 1 \][/tex]

Solve for [tex]\( x \)[/tex]:

[tex]\[ 49 - 1 = 3x \][/tex]

[tex]\[ 48 = 3x \][/tex]

[tex]\[ x = \frac{48}{3} \][/tex]

[tex]\[ x = 16 \][/tex]

Next, since [tex]\( AB = AC \)[/tex]:

[tex]\[ 49 = 18y - 41 \][/tex]

Solve for [tex]\( y \)[/tex]:

[tex]\[ 49 + 41 = 18y \][/tex]

[tex]\[ 90 = 18y \][/tex]

[tex]\[ y = \frac{90}{18} \][/tex]

[tex]\[ y = 5 \][/tex]

The complete question is:

If ABC Is an equilateral triangle, solve for both x and y.

x = _____.

y = _____.
