Answer:

1). Options (B) and (E)

2). First train is going faster than the second train.

Step-by-step explanation:

1). Rate of 2 gallons of vinegar = $3

   Therefore, per gallon rate of vinegar = \frac{3}{2} = $1.5

   In $3 quantity of vinegar chef will get = 2 gallons

   Therefore, quantity of vinegar chef will get in $1 = \frac{2}{3} gallons

Option (A).

Price of 4 gallons = 4 × $1.5 = $6.00

False.

Option (B)

Price of 1 gallon = $1.50

True

Option (C)

Price of 30 gallons = 30 ×$1.5 = $45    

False.

Option (D)

In $2 number of gallons of vinegar chef will get = \frac{2}{3}\times 2=\frac{4}{3} gallons

False

Option (E)

Number of gallons of vinegar chef gets in $1 = \frac{2}{3}

True

Therefore, Options (B) and (E) are the correct.

2). Speed = \frac{\text{Distance}}{\text{Time}}

For first train,

Speed = \frac{30}{\frac{1}{3}}

            = 90 miles per hour

For second train,

 Speed = \frac{20}{\frac{1}{2}}

             = 40 miles per hour

 Since, 90 miles per hour > 40 miles per hour

 First train is going faster than the second train.

Mona wrote 7 tests, and her test average is 93. There will be one more test before the end of the year. What is the lowest grade
olga55 [171]
For this case, the first thing we are going to do is assume that all the tests are worth the same.
 Then, we define a variable:
 x: score of Mona's last test
 We write now the inequality that models the problem:
 \frac{93 + x}{2}  \geq  90
 From here, we clear the value of x: 93 + x  \geq  90*(2) 

93 + x  \geq  180

 x  \geq  180 - 93

 x  \geq  87
 Answer:
 
the lowest grade that Mona can get for her last test so that her test average is 90 or more is:
 
x = 87

19. The areas of corresponding faces of two similar hexagonal prisms are 25 cm² and 121 cm². What is the ratios of the correspon
Pie

ANSWER

I) 5:11

ii) 5:11

iii) 125:1331

EXPLANATION

Let the side lengths be in the ratio:

x:y

This implies that the area will be in the ratio:

\frac{ {x}^{2} }{ {y}^{2} }  =  \frac{25}{121}

Take positive square root.

\frac{x}{y}  =  \sqrt{ \frac{25}{121} }

\frac{x}{y}  =  \frac{5}{11}

Hence the sides are in the ratio:

x:y=5:11

The perimeter of the smaller hexagon is 6×5=30

The perimeter of the larger hexagon is 6×11=66

The ratio of the perimeter is

30:66=5:11

The volume will be in the ratio

5³:11³

125:1331
