Answer:

Tank B

Step-by-step explanation:

A pet store has three fish tanks, each holding a different volume of water and a different number of fish.

a) Tank A has 5 fishes with a volume of 40 liters.

Volume per fish = 40 liters/5 fishes

= 8 liters/fish

b) Tank B has 12 fishes with a volume of 100 liters.

Volume per fish = 100 liters/12 fishes

= 8.33 liters/ fish

c) Tank C has 23 fishes with a volume of 180,000 milliliters.

Convert 180,000 milliliters to liters

1 milliliter = 0.001 liter

180,000 milliliters = x

x = 180,000ml × 0.001 l

x = 180 liters

Volume per fish = 180 liters/23 fishes

= 7.8260869565 volume per fish

Approximately = 7.83 liters/fish

Which tank has the greatest volume per fish?

The tank that had the greatest volume per fish is Tank B at 8.33 liters/ fish

Answer:

question 4. The right answers are 1,3 and 4

Question 5. No they are not balanced.

Step-by-step explanation:

1.

7/9 * 8 = 6  2/9

56/9 = 6 2/9

2.

8 + 11.5 = 20.5

19.5 ≠ 20.5

3.

23.42 - 8 = 15.42

15.42 = 15.42

4.

11 * 8 = 88

88 = 88

5.

40/8 = 6

40/8 ≠ 6

Answer:

The only valid choice is c.

Step-by-step explanation:

Rational Numbers

Rational numbers have the form a/b, where a and b are integers and b is not zero.

In other words, rationals are all numbers that can be written as a fraction.

Examples are -3/7, 11/2, 5, 0

Note the last two numbers are integers, but they are also rationals because an integer can be expressed as a fraction with a denominator of 1.

Irrational numbers are the opposite, they cannot be expressed as a fraction.

a. [tex]\sqrt{7}[/tex] is not an integer since it's irrational. False

c. [tex]\sqrt{25}[/tex] = 5 or -5. It is a rational number because it's an integer. True

b. [tex]\sqrt{16}[/tex] = 4 or -4. It is not an irrational number because it's an integer. False

d. 190 is a rational number. False

The only valid choice is c.

Answer:

The answer is "[tex]\bold{17456.6 \ ft}[/tex]"

Step-by-step explanation:

Please find the complete question in the attached file.

[tex]\sin \theta = \frac{P}{h}\\\\\to BC =x\\\\\to BD =y\\\\[/tex]

The height of tower (AB) = 300 ft

Distance = CD

[tex]\Delta ABC \\\\\sin \theta = \frac{AB}{AC}\\\\\sin (2.5) = \frac{300}{AC}\\\\Ac= \frac{300}{\sin (2.5)}\\\\AC= 6877.68 \\\\\Delta ABD \\\\\sin \theta = \frac{AB}{AD}\\\\\sin (1.3) = \frac{300}{AD}\\\\AD= \frac{300}{\sin (1.3)}\\\\AC= 1322.33[/tex]

calculating CD :

[tex]CD^2 = AC^2 +AD^2 -2\cdot AC \cdot AD \cdot \cos(117^{\circ}) \\\\CD = \sqrt{(6877.68)^2 +(13223.23)^2 -2\cdot (6877.68) \cdot (13223.23) \cdot \cos(117^{\circ})}\\\\CD =\sqrt{47302482.1824 + 174853811.6329 - 82576463.207}\\\\CD= \sqrt{304732757.02}\\\\CD= 17456.6 \ ft[/tex]

Answer:

sample proportion of defective items

Step-by-step explanation:

The p-chart is a type of chart in which the sample is taken periodically from the production process, so as to determine if the population proportion of defective items in the sample falls within the control limits on the chart.

For a P-chart, as the sample size gets larger it turns more into a normal distribution making it possible to approximate the distribution of the proportion defective.

Answer:

y=9

Step-by-step explanation:

they grow together by the same amount

Answer:

27/2...or 13.5 as a decimal

Step-by-step explanation:

the ratio of y and x is y/x or, 9/2 with 9 being the y and 2 being the x

the X changed to 3, so y/3 is the new ratio. Since we have another ratio, we can compare them to get the y

the equation : 9/2=y/3--2x=27--

x=27/2

Answer:

30, 60, 90

Step-by-step explanation:

since there are 6 x's in total, and there are a total of 180 degrees in any triangle, we do 180/6= 30

so now we know x=30, 2x=60, and 3x=90

Answer:$15.66

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

To find how many notes of Rs. 500 he has, we need to find out the total value of all the Rs. 500 notes.

Total value of Rs. 20 notes = 20 × 40

                                             = 800

Total value of Rs. 1000 notes = 1000 × 20

                                                 = 20 000

Total value of Rs. 500 notes = 29 300 - 800 - 20 000

                                                = 8500

No. of Rs. 500 notes = 8500 ÷ 500

                                   = 17

Rohit has total 17 notes of Rs.500

" Unitary method is the process of finding value of one unit using which we can find the value of other units."

According to the question,

Number of Rs.20 notes = 40

Total amount of Rs.20 = 20 × 40

                                     = Rs.800

Number of Rs.1000 notes = 20

Total amount of Rs.1000 = 20 × 1000

                                         = Rs.20,000

Total amount of Rs.20 and Rs.1000 notes = 20,000 +800

                                                                      = Rs.20,800

Made a payment of Rs.29,300

Left amount of Rs.500 notes = 29,300 -20,800

                                                = Rs.8500

Number of Rs.500 notes = 8500 ÷ 500

                                          = 17 notes of Rs.500

Hence, Rohit has total 17 notes of Rs.500.

Step-by-step explanation:

We just need to find a rate where the ratio of miles to gallons is 13:1

This only works for 1) 26 miles 2 gallons since 26/2 = 13/1

Answer:

I think it would be the first one. 26 miles 2 gallons

Step-by-step explanation:

Every gallon would be 13 miles. If you multiply 13 by 2 and 1 gallon by 2, you'll get 26 miles 2 gallons.

Answer:

Please check the attached diagram.

Thus, we conclude that:

In the diagram,

The blue line indicates that the parent function has been shifted 1 unit upward.

Step-by-step explanation:

Let us recall some transformation knowledge.

We know that

if y = f(x), then y = f(x) + b simply means a transformation of (0, b).

In other words, if we add some constant let say 'b' in the output or y-value, the graph simply shifts upward by b units.

Given that

f(x) = x

so

f(x+1) = x+1 means the parent function f(x) = x has been shifted 1 unit upward.

Please check the attached diagram.

Thus, we conclude that:

In the diagram,

The blue line indicates that the parent function has been shifted 1 unit upward.
