Answer:

We have 8 liters of 54% alcohol.

We will add "x" liters of 66% alcohol to make "8 +x" liters of 65% alcohol.

54 * 8 + 66 x =   65 (8 + x)

432 + 66x = 520 + 65x

x = 88 liters

jekas [21]

Answer:

The probability that the selected adult has liver problems is 0.08

Step-by-step explanation:

In this question, from the data given, we want to calculate the probability that an adult selected at random has liver problems.

Let E(L) be the event that an adult has liver problems.

The probability is directly obtainable from the question and it is given as 8%

Thus, the probability that the selected adult has liver problems; P(L) = 8% = 8/100 = 0.08

A semicircular archway is built in front of a garden using 8 congruent granite tiles, as shown in the diagram. Find the area of
iris [78.8K]
Given: 
8 tiles
radius from the center of the archway to the inner edge of the tile. 7 ft.
radius from the center of the archway to the outer edge of the tile. 8 ft = 7 ft + 1 ft.

Area of a semi circle = π r² / 2 
A = (3.14 * (7ft)²) / 2 = (3.14 * 49ft²) / 2 = 153.86 ft² / 2 = 76.93 ft²
A = (3.14 * (8ft)²) / 2 = (3.14 * 64ft²) / 2 = 200.96 ft² / 2 = 100.48 ft²

100.48 ft² - 76.93 ft² = 23.55 ft²
23.55 ft² / 8 tiles = 2.94 ft² per tile.

Need help with this will mark brainiest
Harlamova29_29 [7]

Answer:

a) \boxed{\boxed{\sf  p  = 18 }}

b) \boxed{\boxed{\sf  t  =  3 }}

c) \boxed{\boxed{\sf  p =  6 / by  /5 }}

Explanation -

a) 2/3 p + 10 = r

Value of r = 22 (given)

2/3 p + 10 = 22

2/3 p = 22- 10

2/3 p = 12

p = 12 × 3 /2

p = 6 × 3

<em><u>p</u></em><em><u>=</u></em><em><u>1</u></em><em><u>8</u></em><em><u> </u></em>

b) (-17) + 5k = t

value of k = 4 (given)

(-17) +5 (4) = t

(-17) + 20 = t

<em><u>3</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>t</u></em><em><u> </u></em>

c) 0 = 5p - 3b

b= 2 (given)

0 = 5p - 3(2)

0 = 5p - 6

6 = 5p

<em><u>6</u></em><em><u>/</u></em><em><u>5</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>p</u></em>
