8. At the local pet store, zebra fish cost $2.20 each and neon letras cost $1.80 each. If Marsha bought 15 fish for
a total cost of $29.80, not including tax, how many of each type of fish did she buy?
a. 8 zebra fish, 7 neon tetras
b. 7 zebra fish, 8 ncon tetras
c. 6 zebra fish, 9 neon tetras
d. 9 zebra fisli, 6 ncoe tetras

Answers

Answer 1

Answer:

B. 7 zebra fish, 8 neon tetras

Step by step explanation:

First let's do process of elimination.

X A) 8 x 2.20 = 17.6, 7 x 1.80 = 12.6, 17.6 + 12.6 = 30.2

✔ B) 7 x 2.20 = 15.4, 8 x 1.80 = 14.4, 15.4 + 14.4 = 29.8

X C) 6 x 2.20 = 13.2, 9 x 1.8 = 16.2, 13.2 + 16.2 = 29.4

X D) 9 x 2.20 = 19.8, 6 x 1.8 = 10.8, 10.8 + 19.8 = 30.6

Answer:

[tex] x = 1 \frac{5}{16}[/tex]

Step-by-step explanation:

[tex]8x + \frac{5}{2} = 13 \\ \\ 8x = 13 - \frac{5}{2} \\ \\ 8x = \frac{13 \times 2 - 5}{2} \\ \\ 8x = \frac{26 - 5}{2} \\ \\ 8x = \frac{21}{2} \\ \\ x = \frac{21 }{2\times 8} \\ \\ x = \frac{21}{16} \\ \\ x = 1 \frac{5}{16} \\ [/tex]

A cargo plane can hold at most 38,000 lb. There are 35 boxes on the plane. Each box weighs 625 lb. How many additional boxes of the same weight can the cargo plane hold?

Answers

25 boxes

(35 x 625 = 21875)
38,000 - 21875 = 16125
16125/625 = 25.8
Technically 25.8, but it rounds to 25 boxes

Answer:

25 boxes

Step-by-step explanation:

If RT bisects SU, find each measure ST, RU, SV, SU,

Answers

Answer:

ST = 23

RU = 8

SV = 5

SV = 10

Step-by-step explanation:

Use the knowledge of the properties of a kite to find the measure of ST, RU, SV, and SU as shown below:

✍️Recall: Each pair of adjacent sides of a kite are congruent/equal.

ST and TU are a pair of adjacent sides.

TU = 23

✅Therefore, ST = 23.

RU and RS are a pair of adjacent sides.

RS = 8

✅Therefore, RU = 8.

✍️ Recall: the longer diagonal of a kite bisects the shorter one. This means RT divides SU into two equal parts, namely SV and UV.

Since UV = 5, therefore,

✅SV = 5

SU = UV + SV

✅SV = 5 + 5 = 10

A bisector divides the lines it bisects into equal segments

The measures of ST, RU, SV, SU are 23, 8, 10 and 5 respectively

From the diagram, we have:

[tex]\mathbf{TU = 23}[/tex]

[tex]\mathbf{UV = 5}[/tex]

[tex]\mathbf{RS = 8}[/tex]

Because RT bisects SU, then:

[tex]\mathbf{ST = TU}[/tex]

So, we have:

[tex]\mathbf{ST = 23}[/tex]

Also, we have:

[tex]\mathbf{RU = RS}[/tex]

So, we have:

[tex]\mathbf{RU = 8}[/tex]

Also, we have:

[tex]\mathbf{SV =VU \times 2}[/tex]

[tex]\mathbf{SV =5 \times 2}[/tex]

[tex]\mathbf{SV =10}[/tex]

Lastly, we have:

[tex]\mathbf{SU =VU}[/tex]

[tex]\mathbf{SU =5}[/tex]

Hence, the measures of ST, RU, SV, SU are 23, 8, 10 and 5 respectively

A. 50°
B. 80°
C. 35°
D. 25°

Answers

Answer:

Step-by-step explanation:

A

The measure of SP is 80°, therefore, option (B) is correct.

What is the arc measure?

The center angle that creates the intercepted arc is what is known as the arc measure, which is measured in degrees.

Given that, mKN= 20° and m∠T = 30°.

The formula for the measure of angle ∠T is:

[tex]m\angle{T}= \frac{mSP - mKN}{2}\\30^{\circ} = \frac{mSP - 20^{\circ}}{2}[/tex]

60° = mSP - 20°

mSP = 60° + 20°

mSP = 80°

Hence, the measure of SP is 80°, therefore, option (B) is correct.

Indica que medida hay que adicionar alas siguientes para obtener 1dm cúbico en cada caso a. 27cmcubicos b. 300cm cúbicos c. 0,0001 m cúbicos d. 12,000mm cúbicos

Answers

Answer:

A) Debe agregarse 973 centímetros cúbicos para obtener un decímetro cúbico.

B) Debe agregarse 700 centímetros cúbicos para obtener un decímetro cúbico.

C) Debe agregarse 0,0009 decímetros cúbicos para obtener un decímetro cúbico.

D) Debe agregarse 999988 milímetros cúbicos para obtener un decímetro cúbico.

Step-by-step explanation:

A) Sabemos que un decímetro cúbico equivale a 1000 centímetros cúbicos, entonces la cantidad a adicionar a los 27 centímetros cúbicos para obtener un decímetro cúbico es:

[tex]x = 1000\,cm^{3}-27\,cm^{3}[/tex]

[tex]x = 973\,cm^{3}[/tex]

Por tanto, debe agregarse 973 centímetros cúbicos para obtener un decímetro cúbico.

B) Sabemos que un decímetro cúbico equivale a 1000 centímetros cúbicos, entonces la cantidad a adicionar a los 300 centímetros cúbicos para obtener un decímetro cúbico es:

[tex]x = 1000\,cm^{3}-300\,cm^{3}[/tex]

[tex]x = 700\,cm^{3}[/tex]

Por tanto, deben agregarse 700 centímetros cúbicos para obtener un decímetro cúbico.

C) Sabemos que 0,0001 metros cúbicos equivalen a 0,1 decímetros cúbicos, entonces la cantidad a adicionar a 0,1 decímetos para obtener un decímetro cúbico es:

[tex]x = 1\,dm^{3}-0.1\,dm^{3}[/tex]

[tex]x = 0.9\,dm^{3}[/tex]

Por tanto, deben agregarse 0,0009 decímetros cúbicos para obtener un decímetro cúbico.

D) Sabemos que 1 decímetro cúbico equivale a 1000000 milímetros cúbicos, entonces la cantidad a adicionar 12 milímetros cúbicos es:

[tex]x = 1000000\,mm^{3}-12\,mm^{3}[/tex]

[tex]x = 999988\,mm^{3}[/tex]

Por tanto, deben agregarse 999988 milímetros cúbicos para obtener un decímetro cúbico.

Each school year, the seventh graders who study Life Science participate in a special field trip to the city zoo. In 2010, the school paid $1,260 for 84 students to enter the zoo. In 2011, the school paid $1,050 for 70 students to enter the zoo. In 2012, the school paid $1,395 for 93 students to enter the zoo. A. Is the price the school pays each year in entrance fees proportional to the number of students entering the zoo? Explain why or why not.

Answers

Answer:

The price is proportional to number of students

Step-by-step explanation:

Given

2010: $1260 for 84 students

2011: $1050 for 70 students

2012: $1395 for 93 students

Required

Determine if the price is proportional to number of students

To do this, we simply divide the price by number of students in each year.

[tex]Ratio = \frac{Price}{Students}[/tex]

In 2010

[tex]Ratio = \frac{\$1260}{84}[/tex]

[tex]Ratio = 15[/tex]

In 2011

[tex]Ratio = \frac{1050}{70}[/tex]

[tex]Ratio = 15[/tex]

In 2012:

[tex]Ratio = \frac{1395}{93}[/tex]

[tex]Ratio = 15[/tex]

Notice that the ratio in the 3 years is 15.

Hence, the price is proportional to number of students

A bug was sitting on the tip of the propeller blade 4 ft. Long when the propeller started to rotate. The bug held on for 3 rotations before flying away. How far did the bug travel before it flew away?

Answers

Answer:

75.39 ft

Step-by-step explanation:

r = Radius of the circle drawn by the propeller = 4 ft

Circumference of the circle is

[tex]C=2\pi r\\\Rightarrow C=2\pi 4\\\Rightarrow C=25.13\ \text{ft}[/tex]

So in one rotation the distance traveled by an ant sitting on the blade tip is 25.13 ft.

Now the ant held on for 3 rotations so distance traveled is

[tex]3\times 25.13=75.39\ \text{ft}[/tex]

The bug traveled 75.39 ft.

Five years ago,A's age was four times the age of B.Five years hence A's age will be twice of the age of B. Find their present ages.
_______________________
best of luck ^^
And don't spam =_=​

Answers

Answer:

Let us consider B’s age = X

Then A’s age = 4X

Five years ago

⇒ A’s age = 4X + 5

⇒ B’s age = X + 5

Five years hence

⇒ A’s age = 4X + 5 + 5

⇒ A’s age = 4X + 10

⇒ B’s age = X + 5 + 5

⇒ B’s age = X + 10

From the given question

4X + 10 = 2(X + 10)

4X + 10 = 2X + 20

4X – 2X = 10

2X = 10

X = 5

A’s age = 4X + 5

A’s age = 25 years

B’s age = X + 5

B’s age = 10 years
