<h2>PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT PLEASE </h2>

Step-by-step explanation:

Let the goldfish be G.

• Let the betta fish be B.

Given the following data:

• Total number of fishes = 150 fishes.

• Ratio of G to B = 2:3

• Total ratio= 2 + 3 = 5

To calculate the number of goldfish that the pet store have:

What is ratio?

Ratio can be defined as an expression that is used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.

Mathematically, the number of goldfish in the pet store is given by this expression:

2 G = x 150 5

G = 0.4 x 150

G = 60 fishes.

A Boston subway train traveling at constant speed traveled 10.1 miles in half an hour. What was the speed of the subway train? m

viva [34]

Answer: 20.2 mph

Step-by-step explanation:

Given

Train travels 10.1 miles in half an hour i.e.

Distance $d=10.1\ \text{miles}$

time $t=0.5\ hr$

we know, $\text{distance=speed}\times\text{time}$

Insert the values

$\Rightarrow 10.1=v\times 0.5\\\Rightarrow v=20.2\ mph$

How many 6-digit whole numbers have the digits 2, 0, 2, and 2 as a 4-digit consecutively ordered block with no other digits betw

Yakvenalex [24]

There are 1680 digits 2, 0, 2, and 2 as a 4-digit consecutively ordered block with no other digits between them

<h3>How to determine the selection</h3>

To determine the number of whole numbers, the following must be true

Case 1: If the sequence starts from the first digit

The first digit can be any of the three 2's (i.e. 3 digits)
The second digit can only be 0
The third digit can be any of the remaining 2's (i.e. 2 digits)
The fourth digit can only be the last 2 (i.e. 1 digit)
The fifth digit can be any of 0 - 9 (i.e. 10 digits)
The sixth digit can be any of 0 - 9 (i.e. 10 digits)

So, we have:

$Case\ 1 = 3 * 1 * 2 * 1 * 10 * 10$

$Case\ 1 = 600$

Case 2: If the sequence starts from the second digit

The first digit can be any of 1 - 9 (i.e. 9 digits)
The second digit can be any of the three 2's (i.e. 3 digits)
The third digit can only be 0
The fourth digit can be any of the remaining 2's (i.e. 2 digits)
The fifth digit can only be the last 2 (i.e. 1 digit)
The last digit can be any of 0 - 9 (i.e. 10 digits)

So, we have:

$Case\ 2 = 9 * 3 * 1 * 2 * 1 * 10$

$Case\ 2 = 540$

Case 2: If the sequence starts from the third digit

The first digit can be any of 1 - 9 (i.e. 9 digits)
The second digit can be any of 0 - 9 (i.e. 10 digits)
The third digit can be any of the three 2's (i.e. 3 digits)
The fourth digit can only be 0
The fifth digit can be any of the remaining 2's (i.e. 2 digits)
The last digit can only be the last 2 (i.e. 1 digit)

So, we have:

$Case\ 3 = 9 * 10 * 3 * 1 * 2 * 1$

$Case\ 3 = 540$

The total number of whole numbers is:

$Total = 600 + 540 + 540$

$Total = 1680$

Hence, there are 1680 6-digit whole numbers that the digits

Geometry help math pls

AleksandrR [38]

Answer:

Step-by-step explanation:

The parallelograms are similar, so their corresponding sides are proportional. Write a proportion:

12 / 30 = 16 / PQ

Cross multiply:

12 PQ = 480

Solve for PQ:

PQ = 40

Which has the greater surface area? A 6-centimeter cube or a rectangular prism with a 3 centimeter square base and a height of 1

bazaltina [42]

Answer:

The prism

Step-by-step explanation:

The surface area of a cube is:

$A=6L^2$

where

L is the length of the side

For the cube in this problem,

L = 6 cm

So the surface area of the cube is

$A=6\cdot 6^2 = 36 cm^2$

The surface area of a rectangular prism with squared base is:

$A=2L^2+4Lh$

where

L is the length of the base

h is the height of the prism

For the prism in this problem,

L = 3 cm

h = 12 cm

Therefore,

$A=2\cdot 3^2 + 4(3)(12)=162 cm^2$

So, the prism has a greater surface area.
