Answer:

Area of new garden = 800 ft²

Step-by-step explanation:

Given:

Old fencing = Parameter of old garden = 60 ft

Area of old garden = 200 ft

Find:

Area of new garden if Parameter of new garden is 120 ft

Computation:

Assume;

Length of old garden = l

Width of old garden = b

So,

2[l + b] = 60

l + b = 30

l = 30 - b

Area of old garden = 200 ft

l x b = 200

So,

(30 - b)b = 200

b² - 30b + 200 = 0

b² - 20b - 10b + 200

b(b-20) - 10(b-20)

(b-20)(b-10)

So,

Width of old garden = 10 ft

Length of old garden = 20 ft

New parameter is double

So,

Width of new garden = 10 x 2 = 20 feet

Length of old garden = 20 x 2 = 40 feet

Area of new garden = l x b

Area of new garden = 20 x 40

Area of new garden = 800 ft²

Answer:

c

Step-by-step explanation:

Answer:

using trigonometric ratio sin, which is

sin[tex]\alpha[/tex]=opp/hyp to mean opposite/ hypotenuse

sin 40°= x/9

multiply both sides of this by 9 to remove the 9 in the side we have x, we will have

sin 40°/9=x

sin° 40 =0.7451

so x= 0.7451/9

which is

x= 0.0827888888

to give it in 3 decimal places, the answer will be 0.083 since 7 is the fourth number and is more than five, we add 1 to the 2 making it 3

Answer:

(c) and (e)

Step-by-step explanation:

Given

[tex]Pr = \frac{2}{3}[/tex]

Required

Which 2 options can be used to simulate the given probability.

The two options are (c) and (e)

The proof is as follows;

Option (c)

We have:

[tex]Rolls = 7[/tex]

A cube has 6 faces. So:

[tex]S = \{1,2,3,4,5,6\}[/tex]

[tex]n(S)=6[/tex]

The probability of getting ones, twos, threes, and fours is:

[tex]Pr = \frac{n(1,2,3,4)}{n(S)}[/tex]

In: [tex]S = \{1,2,3,4,5,6\}[/tex]

[tex]n(1,2,3,4) = 4[/tex]

So:

[tex]Pr = \frac{4}{6}[/tex]

Simplify

[tex]Pr = \frac{2}{3}[/tex]

Option (e)

We have:

[tex]White = 10[/tex]

[tex]Red = 5[/tex]

[tex]Count = 7[/tex]

Record the probability of white.

This is calculated as:

[tex]Pr = \frac{White}{Total}[/tex]

[tex]Pr = \frac{White}{White + Red}[/tex]

[tex]Pr = \frac{10}{10+5}[/tex]

[tex]Pr = \frac{10}{15}[/tex]

Simplify

[tex]Pr = \frac{2}{3}[/tex]

Answer:

Absolute minimum / vertex = (5/6,-133/12)

Step-by-step explanation:

Since a is positive, then the absolute maximum is ∞. The absolute minimum would be the vertex of the parabola, meaning x=-b/2a=-(-5)/2(3)=5/6, and y=3(5/6)^2-5(5/6)-9 = -133/12. Therefore, your absolute minimum / vertex is (5/6,-133/12)

Answer:

  6 h

Step-by-step explanation:

The bottom number in the table is half the top number. The missing value is 6 (hours).

__

I like to put the variable in the numerator of a proportion. Here, we can write it as ...

  t/12 = 45/90

Multiplying by 12 gives ...

  t = 12(45/90) = 12(1/2) = 6

It will take Darin 6 hours to mow 12 lawns.

Answer: 6 is going to be the answer!

Multiply the average by number of people:

84.5 x 4 = 338

This means the total of the 4 grades need to equal 338

To find Jonathan’s grade subtract the other 3 grades from 338:

338 - 86 - 92 -70 = 90

Jonathan’s grade was 90

Answer:

d.

Step-by-step explanation:

Answer:

D. $892.50

Step-by-step explanation:

First we find out the interest:

850 * 2.5% = 21.25

Since this is 2 years we multiply the interest by 2.

21.25 * 2 = 42.50

Now we add the interest with the amount borrowed.

850 + 42.50 = $892.50

So, the answer is $892.50 in total.

Hope this helps! :)

Answer:

Blue, yellow and green.

Step-by-step explanation:

Answer:

First we subtract 8,500 from the 18,040. What we get from that is 9540. Now we divide 9,540 by 3.8 and see what we get. What we get is 2510.52631579 which means it would take around 2510.52631579 days to pay 18,040. In total that rounds to 7 years. Rounding up by the way

Answer:

School C.

Step-by-step explanation:

The answer is school C. A u-shaped distribution would have to have values that when plotted, make a "u". In this case, the first and last values have to be the highest, the second and fourth values have to be in the "middle" and the third value has to be at the bottom. This is the case for school C.

Answer:

B. School C

Step-by-step explanation:

Having a U-shaped distribution means that the school would have the least number in the middle value/values and the most at the ends.

School C exhibits this trend because it has the most on the outermost ranges (82 for between 1.5 and 2, and 78 for between 3.5 and 4.0), as well as the least number for the middle value (26 for 2.5-3.0

The numbers inbetween also follow the trend, as you can see if you read down the column of school C, the numbers decrease as you get to 2.5-3.0 and increase again to 4.0

Step-by-step explanation:

Considering speed of Noha = 4miles per hour

and speed of andrew = 2 miles/hour

The distance between Noha and andrew = 15 miles

Case 1: when they are travelling towards each other( opposite direction)

Then their relative speed becomes = 4+2 = 6miles/hour

Time taken to meet = Distance/relative speed = 15/6 = 2.5 hours

Case2: When they are travelling same direction

Then their relative speed becomes = 4-2 = 2 miles/hour

Time taken to meet = Distance/ relative speed = 15/2 = 7.5 hours
