Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

since we know the Hyp and the Opp of the angle  pick SOH

Sin(Ф)= 42 / 42[tex]\sqrt{2}[/tex]

∅ = arcSin( 42 / 42[tex]\sqrt{2}[/tex] )

∅ = 45 °

1.What percent of the entire garden is devoted to roses and zinnias
2.If alyssum is planted outside of the petunias and the pattern shown in the diagram continues,
how many square feet are devoted to alyssum

Answers

Answer:

1. 30% 2. 160 square feet

Step-by-step explanation:

1.The entire area of the garden is 20x16=320 square feet

The area of the Zinnias(including roses) is 8x12 = 96 square feet

To get the percent, we have to divide the smaller number by the bigger number and multiply by 100, like 96/320x100=30%

2. The width progresses in the first rectangle by four 8 to 12, then again by four 12, 16 and again by four 16 to 20, which means that the next rectangle would have a width of 20+4=24. Doing the sale analysis for the height, we get that the increase is with 4 feet at a time or the new rectangle would have a width of 24 and height of 20, which means a total area of 480 feet. We would have to subtract all other rectangles and the new area would be 480 - (20x16) = 160 square feet

can I pls have brainliest?

1. 30%

Conveniently enough, the roses and zinnias are right next to each other, within the same rectangle. 12 x 8 = 96 square feet.
But we need to know what percentage that area takes place within the whole garden, so we need the garden’s area too. 20 x 16 = 320 square feet.
Now, to find the percentage of roses and zinnias within the garden. We start by putting it as a fraction, 96/320, which simplifies to 3/10. You can now easily tell that 3/10, as a percentage, is 30%

2. 160 square feet

First, you have to analyze the blueprint and see what the pattern is for every new plant added. 4 is added to the length, and 4 is added to the width. 4 would be added from 20 and 4 would be added from 16 if alyssum was added, giving 24 x 20 = 480 square feet.
We now have to subtract the old area of the garden from the new one we just calculated. And we already calculated the old garden from the last problem!
480 - 320 = 160 square feet.

Answers

Answer:

(D) 81 feet      

Step-by-step explanation:

From the figure drawn, it is given that AB is parallel to DE, in ΔABC and ΔCDE, we have

∠BAC=∠DEC(Alternate angles)

∠ACB=∠DCE(Vertically opposite angles)

Thus, by AA rule, ΔABC is similar to ΔCDE.

Since the line connecting from the whales to the sharks is parallel to the line connecting from the penguins to the fish tanks, the triangles shown in the figure are similar. Using the property of similar triangles.

Answer:

29: 81.5

30: 9

31: 180

Step-by-step explanation:

29: if c=9 then squared then it is 9 times 9 which equals 81 then a equals 1/2 which is 0.5 in fraction so we add 81 + 0.5 =81.5

30: c equals 9 which we times by 2 and equals 18 then we times 18 by a which is 0.5 and it goes back down to 9

31: b equal 15 and it is squared so we times 15 by 15 which equals 225 and then we multiply 5 times c and c is 9 so 5 times 9 is 45 and 225 minus 45 equals 180

Histogram, because a large number of scores are reported as ranges. The correct option is A.

What is a histogram?

The graphic representation of data points arranged into user-specified ranges is called a histogram. The histogram, which resembles a bar graph in appearance, condenses a data series into an intuitive visual by collecting numerous data points and organizing them into logical ranges or bins.

Given that a group of 23 students participated in a math competition. Their scores are below:

Score (points)          Number of Students

20- 29                                   4

30 – 39                                 7

40 – 49                                 5

50 – 59                                 4

60 – 69                                 3

If the above data is large data then it will be represented by the histogram. Therefore, the correct answer is A because of the histogram, because a large number of scores are reported as ranges. The correct option is A.
