Answer:4 gallons of water ... 30 plants

x gallons of water = ? ... 45 plants

If you would like to know how much water will it take to water 45 plants, you can calculate this using the following steps:

4 * 45 = x * 30

180 = 30 * x    /30

x = 180 / 30

x = 6 gallons of water

Result: You will use 6 gallons of water to water 45 plants.

Answer:

The degrees of freedom for this sample are 27.

The sample size to get a margin of error equal or less than 0.3656 is n=4450.

Step-by-step explanation:

The degrees of freedom for calculating the value of t are:

df=n-1=28-1=27

With 27 degrees of freedom and 95% confidence level, from a table we can get that the t-value is t=2.052.

The sample size to get a margin of error equal or less than 0.3656 can be calculated as:

MOE=t\cdot s/\sqrt{n}\\\\n=\left(\dfrac{t\cdot s}{MOE}\right)^2=\left(\dfrac{2.052\cdot 11.8841}{0.3656}\right)^2=66.7^2\\\\\\n=4449.13\approx4450

lutik1710 [3]

Answer:

<em><u>The answer is</u></em>: <u>a. 30 year FHA, 3.5% down at a fixed rate of 6.5%.</u>

<u />

Step-by-step explanation:

If Eli wants to pay as little as possible, and we start with a 30-year mortgage, among the percentages that must be paid, <u>the lowest is 3.5%</u>, in terms of the fixed rate, <u>the lowest is 5%</u>, but if we see the amount of <u>30 years, it is 10%</u>, so although the fixed rate of <u>6.5% is higher than that of 5%, the payment is only made once</u>, and the difference is not so much compared to 10% for 30 years.

<em><u>The answer is</u></em>: <u>a. 30 year FHA, 3.5% down at a fixed rate of 6.5%.</u>

Adair suggests that they package together the fries and soda in a combo for a $0.75 discount. lf the student council pays $0.85
Ira Lisetskai [31]

Answer:

$58.50

Step-by-step explanation:

It is given that the student council pays

For per french fry = $0.85

For per soda fry = $1.20

Discount on the combo of  fries and soda = $0.75

Total revenue for one combo = $0.85 + $1.20 - $0.75 = $1.30

Since the total revenue for one combo is $1.30, therefore the total revenue for 45 combo is

Total revenue for 45 combo = 45 × $1.30 = $58.50

Therefore, they will make $58.50 if they sell 45 combos.

harkovskaia [24]

here's the solution,

we know that, sum of <u>measures</u> of each interior angle of a <u>triangle</u> = <u>180°</u>

<u>F</u><u>igure</u><u> </u><u>1</u><u>.</u>

=》

40 + 32 + 9x + 9 = 180

=》

81 + 9x = 180

=》

9x = 180 - 81

=》

x =  \frac{99}{9}

=》

x = 11

<u>Figure</u><u> </u><u>2</u><u>.</u><u> </u>

=》

42 + 63 + 4x + 15 = 180

=》

120 + 4x = 180

=》

4x = 180 - 120

=》

4x = 60

=》

x =  \frac{60}{4}

=》

x = 15

<u>Figure</u><u> </u><u>3</u><u>.</u>

=》

45 + 45 + 3x - 21 = 180

=》

3x + 69 = 180

=》

3x = 180 - 69

=》

3x = 111

=》

x =  \frac{111}{3}

=》

x = 37
