(1) 34.8 liters

(2) $63.55

Solution:

(1) There is a mistake in question. It is 42 liters.

Total gasoline a car can hold = 42 liters

Liters of gasoline filled in beginning of the week = 35.8

Liters of gasoline used during the week = 28.6

Remaining liters of gasoline in the tank = 35.8 – 28.6

                                                                  = 7.2 liters

Quantity of gasoline need to buy to fill the tank completely

                               = Total capacity – Remaining gas in the tank

                               = 42 liters – 7.2 liters

                               = 34.8 liters

Hence Alberto need to buy 34.8 liters of gasoline to fill the tank.

Option B is the correct answer.

(2)

Shamika earns in first week = $25.75

Shamika earns in next week = $37.80

Total money Shamika have = First week earning + Second week earning

                                              = $25.75 + $37.80

                                              = $63.55

Don't add or subtract spending money, because the question is how much she have from these two weeks.

Hence Shamika have $63.55 from these two weeks.

Leo's bank balances at the end of months 1, 2, and 3 are $1500, $1530, and $1560.60,
grandymaker [24]

Leo's balance after 9 months will be: $1757.49

Step-by-step explanation:

It is given that the balances follow a geometric sequence

First of all, we have to find the common ratio

Here

a_1 = 1500\\a_2 = 1530\\a_3 = 1560.60

Common ratio is:

r = \frac{a_2}{a_1} = \frac{1530}{1500} = 1.02\\r = \frac{a_3}{a_2} = \frac{1560.60}{1530} = 1.02

So r = 1.02

The general form for geometric sequence is:

a_n = a_1r^{n-1}

Putting the first term and r

a_n = 1500 . (1.02)^{n-1}

To find the 9th month's balance

Putting n=9

a_9 = 1500 . (1.02)^{9-1}\\= 1500.(1.02)^8\\=1757.4890

Rounding off to nearest hundredth

$1757.49

Hence,

Leo's balance after 9 months will be: $1757.49

Answer:

Hello! The answer to your question will be below.

Step-by-step explanation:

The answer would be clockwise.

So point k was rotated 90 degrees clockwise.....

Review.....

Question:

Point K is rotated 90 degrees. The coordinate of the pre-image point K was (2,-6) and it’s image K’ is at the coordinate (-6,-2).Find the direction of the rotation.

THE DIRECTION OF THE ROTATION WAS CLOCKWISE.

Hope this helps! :)

skad [1K]

Answer:

1. x^2-9x+18

2. 2x^2-4x-16

3. 3x^2-19x-14

4. 6x^2 +14x + 8

Step-by-step explanation:

1. (x-3)(x-6)

x^2 - 6x - 3x +18 = x^2-9x+18

2. (2x+4)(x-4)

2x^2-8x+4x-16 = 2x^2-4x-16

3. (x-7)(3x+2)

3x^2+2x-21x-14 = 3x^2-19x-14

4. (3x+4)(2x+2)

6x^2+6x+8x+8 = 6x^2 +14x + 8
