Answer:

16%

Step-by-step explanation:

What you need to do is add both 48 and 240 together. That gives you a total of 288 flowers. Now you need to divide 48 by 288 because that will give you your percentage. In this case, it's 16%.

Answer:

Here.

Step-by-step explanation:

You add the number of flowers together to get the total number- 48 + 240 is 288.

48 should be 16.66%, as 288 divided by 6 is 48.

The tile along the edge of a triangular community pool needs to be replaced. Which expression represents the total perimeter of

topjm [15]

The total perimeter of the pool edge $\boxed{12{x^2} + 15}$ .Option A is correct.

Further Explanation:

The formula of area of square can be expressed as follows,

${\text{Area}} = \dfrac{1}{2} \times \left( b \right) \times \left( h \right)$

The formula of perimeter of the triangle can be expressed as follows,

$\boxed{{\text{Perimeter}} = 3 \times s}$

Here, s represents the side of square.

Given:

The options are as follows,

A. ${12x^2} + 15$

B. ${20x^2} + 25$

C. ${12x^2} + 8x +25$

D. ${24x^2} + 16x + 50$

Explanation:

Option A is ${12x^2} + 15.$

12 and 15 are the multiple of 3.

$\begin{aligned}{\text{Perimeter}} &= 12{x^2} + 15\\&= 3\left( {4{x^2} + 5} \right)\\\end{aligned}$

Therefore, the perimeter of the pool is ${12x^2} + 15.$

The total perimeter of the pool edge $\boxed{12{x^2} + 15}$ .Option A is correct.

Option A is correct.

Option B is not correct.

Option C is not correct.

Option D is not correct.

kirza4 [7]

Answer: parameter: The proportion of registered voters who will vote Yes on the measure.

Sample: The 1000 registered voters who participated in the study.

Statistic: The proportion of the 1000 registered voters that were surveyed who will vote Yes on the measure.

Variable: Yes or No for each registered voter

Population: All registered voters in the US

Data: The list of Yes and No answers that were given by the 1000 participants in the study.

Step-by-step explanation:

Definitions of the given terms:

Population: Large groups of individuals having similar characteristics as per the researcher's point of view.

Sample: It is a subset of the population used to represent it.
Parameter: Measure of particular characteristics in the population.
Statistic: Measure of particular characteristics in the sample.
Variable: Characteristics that vary.
Data: A collected information facts and statistics.

Hence, by using the above definitions, we have

Parameter: The proportion of registered voters who will vote Yes on the measure.
Sample: The 1000 registered voters who participated in the study.
Statistic: The proportion of the 1000 registered voters that were surveyed who will vote Yes on the measure.
Variable: Yes or No for each registered voter.

If y varies directly as x^2 and y = 72 when x =3, what is the value of y when x = 6?

Komok [63]

Answer:

288

Step-by-step explanation:

$y \alpha x {}^{2}$

then

$y = kx {}^{2}$

72=9k

dividing both side by 9

k=72÷9

$y = 8 {x}^{2}$

y=8×6²

y=8×36

y=288

Help plz

LUCKY_DIMON [66]

Answer:

h = 0.64 ft

Step-by-step explanation:

$s = \frac{14 + 12 + 6}{2} = \frac{32}{2} = 16 \: ft \\ \\ A = \sqrt{(s - 14)(s - 12)(s - 6)} \\ \\ A = \sqrt{(16 - 14)(16 - 12)(16 - 6)} \\ \\ A = \sqrt{(2)(4)(10)} \\ \\ A = \sqrt{80} \\ \\ A = 8.94427191\\ \\ A \approx 8.94 \: {ft}^{2}$

A = 14h

8.94427191 = 14h

h = 8.94/14

h = 0.638571429

h = 0.64 ft
