Answer:

To determine how many vases the florist will need to put all of the flowers in vases, we need to divide the total number of flowers by the number of flowers she wants to put in each vase.

The florist has 134 flowers, and she wants to put 8 flowers in each vase. So, the number of vases she will need can be calculated as follows:

Number of vases = Total number of flowers / Number of flowers per vase

Number of vases = 134 flowers / 8 flowers per vase

Number of vases = 16.75 vases

Since we cannot have a fraction of a vase, we need to round up to the nearest whole number of vases. Therefore, the florist will need 17 vases to put all of the flowers in vases.

In summary, the florist will need 17 vases to put all of the 134 flowers in vases, with each vase containing 8 flowers.

Answer:

17 vases

Step-by-step explanation:

134/8 = ...

13/8 is 1 remainder 5

54/8 is 6 remainder 6

since u cannot leave any flowers out u need one extra vase for the other 6 flowers.

so the answer is 17

Answer:

Step-by-step explanation:

a) m∠3 + m∠5 = 180° (interior angles on the same side of the transversal)

(12x + 5) + (30x - 35) = 180°

12x + 5 + 30x - 35 = 180°

42x - 30 = 180°

42x = 180° + 30°

42x = 210°

x = 210/42 (by transposing)

x = 5°

By substituting the value of x,

m∠3 = 12x + 5 = 12(5) + 5 = 60 + 5 = 65°

m∠5 = 30x - 35 = 30(5) - 35 = 150 - 35 = 115°

m∠3 = m∠6 = 65° (alternate interior angles are equal)

m∠4 = m∠5 = 115° (alternate interior angles are equal)

m∠5 = m∠8 = 115° (vertically opposite angles are equal)

m∠6 = m∠7 = 65° (vertically opposite angles are equal)

m∠4 = m∠1  = 115° (vertically opposite angles are equal)

m∠3 = m∠2 = 65° (vertically opposite angles are equal)

m∠5 = m∠8 = m∠4 =m∠1 = 115°

m∠3 = m∠2 =m∠6 = m∠7 = 65°

Hope you understood!!

The value of x is 5 while the angles ∠1 = ∠4 = ∠5 = ∠8 = 115° and ∠2 = ∠3 = ∠6 = ∠7 =  65°.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

(a)

As per the given,

m∠3 = (12x + 5) degrees and m∠5 = (30x - 35)

Since, ∠3 = ∠7

∠7 = 180° - ∠5

(12x + 5) = 180 - (30x - 35)

12x + 30x = 180 + 35 - 5

42x = 210

x = 5

(b)

∠3 = 12 x 5 + 5 = 65°

∠2 = ∠3 = 65°

∠1 = 180° - ∠3 = 115°

∠1 = ∠4 = 115°

All corresponding angles will be the same.

∠5 = ∠8 = 115°

∠7 = ∠6 = 65°

Hence "In contrast to the angles ∠1 = ∠4 = ∠5 = ∠8 = 115° and ∠2 = ∠3 = ∠6 = ∠7 = 65°, x has a value of 5".

The percent of the increase, rounded to the nearest tenth of a percent, concerning the sales of boxes of cookies that Molly sold last month and this month, is 11.5%.

The percentage increase can be determined by finding the difference or the amount of increase in sales.

This difference is divided by the previous month's sales and multiplied by 100.

The total number of boxes of cookies Molly's Scout Troop sold last month = 148

The total number sold this month = 165

The increase = 17 (165 - 148)

Percentage increase = 11.5% (17 ÷ 148 x 100)

Answer: 2 years

Step-by-step explanation:

The exponential growth function is given by :-

\(y=A(1+r)^x\) (i)

, where A = initial value , r = rate of growth and  x= time period.

As per given ,

A= 242

r= 12% = 0.12

To find : t when y= 300.

Put all the values in (i)

\(300=242(1+0.12)^x\\\\\Rightarrow\ \dfrac{300}{242}=(1.12)^x\\\\\Rightarrow\ 1.23967=(1.12)^x\)

Taking log on both sides , we get

\(\log (1.2396) = t \log (1.12)\\\\\Rightarrow\ 0.09328=t(0.049218)\\\\\Rightarrow t=\dfrac{0.09328}{0.049218}=\approx2\)

hence, it will take 2 years.

Truly, I'm not sure what type of problem this is, but most people don't favor all the seasons. If there is more to the problem, I would be glad to help further.

Answer:

One possible way to estimate how many people out of 20 would say that they like all seasons is to use a simple random sample. A simple random sample is a subset of a population that is selected in such a way that every member of the population has an equal chance of being included. For example, one could use a random number generator to assign a number from 1 to 20 to each person in the population, and then select the first 20 numbers that appear. The sample would then consist of the people who have those numbers.

Using a simple random sample, one could ask each person in the sample whether they like all seasons or not, and then calculate the proportion of positive responses. This proportion is an estimate of the true proportion of people in the population who like all seasons. However, this estimate is not exact, and it may vary depending on the sample that is selected. To measure the uncertainty of the estimate, one could use a confidence interval. A confidence interval is a range of values that is likely to contain the true proportion with a certain level of confidence. For example, a 95% confidence interval means that if the sampling procedure was repeated many times, 95% of the intervals would contain the true proportion.

One way to construct a confidence interval for a proportion is to use the formula:

p ± z * sqrt(p * (1 - p) / n)

where p is the sample proportion, z is a critical value that depends on the level of confidence, and n is the sample size. For a 95% confidence interval, z is approximately 1.96. For example, if out of 20 people in the sample, 12 said that they like all seasons, then the sample proportion is 0.6, and the confidence interval is:

0.6 ± 1.96 * sqrt(0.6 * (1 - 0.6) / 20)

which simplifies to:

0.6 ± 0.22

or:

(0.38, 0.82)

This means that we are 95% confident that the true proportion of people who like all seasons in the population is between 0.38 and 0.82. Therefore, based on this sample and this confidence interval, we would expect between 8 and 16 people out of 20 to say that they like all seasons in the population.

(200 - 100√2) / 16 is the rectangular form of the product c1*c2 for an equilateral triangle's vertices.

A triangle is a three-sided polygon that is sometimes (but not always) referred to as the trigon. Every triangle has three sides and three angles, which may or may not be the same.

Here,

An equilateral triangle is a triangle with three equal sides. If 3-2i, 6-i, and c form the vertices of an equilateral triangle, then the distance between 3-2i and 6-i is equal to the distance between 3-2i and c.

The distance between two complex numbers a + bi and c + di can be found using the formula:

√((c - a)² + (d - b)²)

So, the distance between 3-2i and 6-i is:

√((6 - 3)² + (-1 - (-2))²) = √((3)² + (1)²) = √(9 + 1) = √10

And the distance between 3-2i and c is:

√((c - 3)² + (c - (-2))²) = √((c - 3)² + (c + 2)²)

Since these distances must be equal, we have:

√((c - 3)² + (c + 2)²) = √10

Squaring both sides:

(c - 3)² + (c + 2)² = 10

Expanding both sides:

c² - 6c + 9 + c² + 4c + 4 = 10

Combining like terms:

2c² + 10c + 5 = 10

Subtracting 10 from both sides:

2c² + 10c - 5 = 0

This is a quadratic equation, which can be solved using the quadratic formula:

c = (-b ± √(b² - 4ac)) / 2a

Where a = 2, b = 10, and c = -5. Plugging these values into the formula:

c = (-10 ± √(10² - 4 * 2 * -5)) / 2 * 2

c = (-10 ± √(100 + 40)) / 4

c = (-10 ± √(140)) / 4

c = (-10 ± 10√2) / 4

So there are two complex solutions, c1 = (-10 + 10√2) / 4 and c2 = (-10 - 10√2) / 4.

The product of these two solutions is:

c1 * c2 = ((-10 + 10√2) / 4) * ((-10 - 10√2) / 4)

= (100 - 100√2 + 100) / 16

= (200 - 100√2) / 16

(200 - 100√2) / 16 is the answer in rectangular form for the product c1*c2 for the vertices of an equilateral triangle.

The equation of a line can be found by using the following expression:

Where (x1, y1) and (x2, y2) are known points on the line and b is the y-intercept.

The y-intercept is the value at which the line crosses the y-axis, this value has a correspondent x-coordinate of 0. To find it we need to look at the table and find which value of y has a x coordinate equal to 0, this value is 3. The y-intercept is equal to 3.

To calculate the slope we need two points we will choose (1,1) and (0,3). Applying these points on the expression we can find the slope:
