Answer 1

A)The gallons of gas needed to make 320 miles = 24 gallons of gas

Explanation

Step 1: To find the gallons of gas needed to make 1mile

The car uses 15 gallons of gas to make 200 miles.

from this we get,

gallons of gas needed to make 1mile = 15/200 =3/40

Step 2: To find the gallons of gas needed to make 320 miles

Therefore, the gallons of gas needed to make 320 miles = 320 x(3/40) = 24 gallons of gas

6 cups of flour would be needed to make an entire batch of cookies.

Given that,
A recipe calls for 1 1/2 cups of flour to make 1/4 of a batch of cookies.

To determines the number of cups of flour that would be needed to make an entire batch of cookies.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,

1 1/2 cups of flour => 1/4 batch of cookies
3/2 cups of flour => 1 / 4 batch of cookies
Multiply by  both sides,
4 * 3 / 2 cups of flour => 4 * 1 / 4 batch of cookies
6 cups of flour => 1 batch of cookies

Thus, 6 cups of flour would be needed to make an entire batch of cookies.

Un aljibe de 12.4 m de profundidad se encuentra totalmente lleno de agua. ¿Cual es la presión en el fundo debido únicamente al peso del agua? Si sabemos que la presión atmosférica total es de 75 cm de hg en el SI ¿Cual es la presión total en el fondo de la piscina?

Answers

Answer:

a) p = 121644 Pa

b) [tex] p_{T} = 221644 Pa [/tex]  

Step-by-step explanation:

a) La presión en el fondo debido únicamente al peso del agua se puede calcular usando la siguiente ecuación:

[tex] p = \rho gh [/tex]

En donde:

ρ: es la densidad del agua = 1000 kg/m³

g: es la gravedad = 9.81 m/s²

h: es la profundidad = 12.4 m

[tex] p = \rho gh = 1000 kg/m^{3}*9.81 m/s^{2}*12.4 m = 121644 Pa [/tex]

Entonces, la presión en el fondo debido al agua es 121644 Pa.

b) Para hallar la presión total en el fondo debemos ahora considerar la presión atmosférica:

[tex] p_{T} = p_{0} + \rho gh [/tex]  

En donde p₀ es la presión atomsférica = 75 cmHg

[tex] p_{T} = 750 mmHg\frac{1 Pa}{0.0075 mmHg} + 121644 Pa = 221644 Pa [/tex]

Por lo tanto, la presión total en el fondo es 221644 Pa.

Step-by-step explanation:

You are enclosing a rectangular garden with feet of ornamental fencing. The area of the garden is square feet. What are the dimensions of the​ garden?

Answers

Answer:

The length and width of the rectangular garden are 20 feet and 10 feet.

Step-by-step explanation:

Given that the length of fencing = 60 feet

The area of the garden = 200 sq. feet.

As the length of the fencing is equal to the perimeter of the garden, so the perimeter of the rectangular garden is 60 feet.

Let l and b be the length and width of the rectangular garden.

So, the perimeter of the garden = 2(l+b)=60

[tex]\Rightarrow l+b=60/2=30[/tex]

[tex]\Rightarrow l=30-b\cdots(i)[/tex]

The area of the rectangular garden [tex]= l\times b=200[/tex]

[tex]\Rightarrow (30-b)b=200[/tex] [from equation (i)]

[tex]\Rightarrow 30b-b^2=200[/tex]

[tex]\Rightarrow b^2-30b+200=0[/tex]

[tex]\Rightarrow b^2-10b-20b+200=0[/tex]

[tex]\Rightarrow b(b-10)-20(b-10)=0[/tex]

[tex]\Rightarrow (b-20)(b-10)=0[/tex]

[tex]\Rightarrow b-20=0 \;or\; b-10=0[/tex]

[tex]\Rightarrow b= 20\;or\; 10[/tex]

Now, from equation (i),

If b=20 than l= 30-20=10

or if b=10 than l=30-10=20.

Hence, the length and width of the rectangular garden are 20 feet and 10 feet.

If you randomly select a card from a well-shuffled standard deck of 52 cards, what is the probability that the card you select is not a 4? (Your answer must be in the form of a reduced fraction.)

Answers

Answer:

12/13

Step-by-step explanation:

A standard deck of cards has four suites

Total number of cards = 52

Total number of cards which are 4 is = 4

The probability that the card selected is 4 = 4/52 = 1/13

S,  the probability that the selected card is not a 4 = 1 - (1/13 )= 12/13

1) IF DE = 9, find BC
2) if m<ADE = 80, then find m< ABC
3) If DE = 2x + 7 , and BC = 7x - 1, find BC​

Answers

Answer:

1. BC = 18

2. m<ABC = 80°

3. x = 5

Step-by-step explanation:

1. If DE = 9, therefore:

[tex] BC = 2 \times 9 = 18 [/tex] (based on the midsegment theorem, DE is half the length of the third side, BC)

2. m<ADE = 80°, then,

m<ABC = 80°

This is because m<ADC and m<ABC are corresponding angles. Corresponding angles are congruent.

3. DE = 2x + 7 , and BC = 7x - 1, find BC

Thus:

[tex] BC = 2 \times DE [/tex] (midsegment theorem)

[tex] 7x - 1 = 2 \times (2x + 7) [/tex] (substitution)

Solve for x

[tex] 7x - 1 = 4x + 14 [/tex]

Collect like terms

[tex] 7x - 4x = 1 + 14 [/tex]

[tex] 3x = 15 [/tex]

Divide both sides by 3

x = 5

Nicholas wanted to save money to buy his girlfriend a ring. He can save $15 a week and needs at least $200 for the ring he wants to buy. If he starts with
$50 already, will he have enough for the ring within 10 weeks?

Answers

Answer:

Yes, he will have enough in 10 weeks

Step-by-step explanation:

1 - Set up an equality statement to prove

He starts with 50, and earns 15 per week to earn more than 200.

Therefore,

50 + 15 per week for 10 weeks must be greater than or equal to 200

or

50 + 15x ≥ 200

2 - "Plug and chug" to solve

50 + 15x ≥ 200

50 + 15(10) ≥ 200

50 + 150 ≥ 200

200 ≥ 200

3 - Prove

Is 200 greater than equal to 200? Yes its equal thus this statement is valid which means he will have enough in 10 weeks

Ben is going to make 1/4 pound burgers for a barbecue next weekend. He is planning on making 19 burgers. How much hamburger meat will he need to make 19 quarter pound burgers?

Answers

Answer:

4.75 pounds of hamburger meat

Step-by-step explanation:

In order to calculate the total amount of hamburger meat that Ben would need we would need to multiply the total number of burgers that he wants to make (19) by the amount of meat each burger will use (1/4 pound or 0.25 pound). Therefore, we would do the following...

19 * 0.25 = 4.75 pounds

Finally, we can see that Ben would need a total of 4.75 pounds of hamburger meat to make 19 equal sized 1/4 pound burgers.

One month Tom rented 6 movies and 5 video games for a total of $50. The next month he rented 2 movies and 3 video games for a total of $24 . Find the rental cost for each movie and each video game.

Answers

Answer:rental cost for each movie =$3.75 and for video games = $5.5

Step-by-step explanation:

Step 1 Let the cost of movie = x

and cost of video game = y

Cost at  Ist Month for 6 movies and 5 video games for a total of $50 will  be

6x+ 5y= $50------- Equation 1

Cost at  2nd Month for 2 movies and 3 video games for a total of $24 will  be

2x+ 3y= $24--------  Equation 2

Step 2--- Solving

6x+ 5y= $50------- Equation 1

2x+ 3y= $24--------  Equation 2

Multiplying equation 2 by (3)

6x+ 5y= $50------- Equation 1

6x+ 9y= $72--------Equaton 3

subtracting  equation 1 from equation 3

9y-5y=22

4y= 22

y=22/4= 5.5

Putting the value of y = 5.5 in equation 1

6x+ 5y= $50

6x + 5(5.5)= $50

6x =50-27.5

6x=22.5

x=22.5/6

x =3.75

Therefore rental cost for each movie =$3.75 and for video games = $5.5
