Jose burns 8 calories per minute. Does Jose burn more than 500 calories per hour?​

Answer:

F = 128.25 Newtons

Step-by-step explanation:

The force of an object is the combination of its mass and its acceleration. The formula is:

F = ma

Where

F is the force in Newtons

m is the mass in (kilograms)

a is the acceleration (in m/s^2)

Given,

m = 27

a = 4.75

We now need to find the force, so we plug the known information and solve easily:

F = ma

F = 27 * 4.75

F = 128.25 Newtons

Answer:

5 Male fishes, and 15 Female fishes

Step-by-step explanation:

We have two unknowns: The number of lady fishes (let's represent this number with "L"), and the number of male fishes (let's name this unknown number "M"). So now we need to create two equations to help us solve for these unknowns.

Use the actual sentences they give you to create the equations:

a) "75% of the total number of fishes are female"

Notice that the total number of fishes is the addition of the number of ladies plus the number of males; that is the total is "L+M". According to the sentence, 75% (which in math terms is written as "0.75") of this total number equals the number of lady fishes:

[tex]0.75 \,*\,(L+M)=L[/tex]

now we work a little the algebra indicated in this equation to simplify it a bit:

[tex]0.75 \,*\,(L+M)=L\\0.75\,L+0.75\,M=L\\0.75\,M=L-0.75\,L\\0.75\,M=0.25\,L\\L=\frac{ 0.75\,M}{0.25}\\L=3\,M[/tex]

which tells us that the number of lady fishes is 3 times thenumber of male fishes.

b) Now the second equation based on the words:

"Lady fishes are 5 more than twice the male fishes"

"Twice the male fishes" can be written as: "2M"

so now we write this sentence as:

[tex]L=2\,M+5[/tex]

Now we combine the two equations by using in the second one the replacement for "L" in terms of "M" that we found in the first equation (that is: "L = 3 M") , so we obtain an equation with just one unknown (M) and we can solve for it:

[tex]L=2\,M+5\\3\,M=2\,M+5\\3\,M-2\,M=5\\M=5[/tex]

Which tells us that the number of male fishes in the tank is "5".

We can use now our first simplified equation to find the number of lady fishes:

[tex]L=3\,M\\L=3\,(5)\\L=15[/tex]

So, there are 15 female fishes in the tank.

a. An equation that represents the situation is y = 9 x

b. The best Interpretation of the slope is " It costs $9 per hour to rent a kayak " ⇒ 2nd answer

c. It costs $45 to rent the kayak for 5 hours

Step-by-step explanation:

Proportional relationship means two quantities vary with each other

If y varies directly as x, then

The cost " y " in (dollars) to rent a kayak is proportional to the

number of hours  " x " that you rent the kayak

∵  y ∝ x

∴ y = k x , where k is the constant of proportionality

∵ It costs $27 to rent the kayak for 3 hours

∴ y = 27 and x = 3

- Substitute these value in the equation above

∴ 27 = k (3)

- Divide both sides by 3

∴ 9 = k

∴ y = 9 x

a. An equation that represents the situation is y = 9 x

∵ The slope is the unit rate of the cost

∵ The slope = 9

∴ The unit rate is $9 per hour

b. The best Interpretation of the slope is " It costs $9 per hour to rent a kayak "

∵ y = 9 x

∵ x = 5 hours

- Substitute x by 5 in the equation above

∴ y = 9 (5) = $45

c. It costs $45 to rent the kayak for 5 hours

Final answer:

The equation representing the situation is y = 9x. The slope indicates that it costs $9 per hour to rent the kayak. For 5 hours of rental, the cost is $45.

Explanation:

If the cost (y) to rent a kayak is proportional to the number (x) of hours the kayak is rented, and it costs $27 to rent the kayak for 3 hours, we can use this information to write a linear equation that represents the situation. The cost is $9 per hour since $27 ÷ 3 hours = $9 per hour. Our equation is thus y = 9x.

For the interpretation of the slope, since we've determined the cost is $9 per hour, the correct interpretation of the slope is that it costs $9 per hour to rent the kayak.

To find out how much it costs to rent the kayak for 5 hours, we simply plug in x = 5 into our equation y = 9x. So, it costs y = 9 × 5 = $45 to rent the kayak for 5 hours.

Weight of the astronaut on Earth = 49 kg

Weight of the astronaut on the moon = 1/6 * 49 kg

Weight of the astronaut on Mars = 0.38 * 49 kg

2. What is the  difference between the astronaut's weight on Mars and her  weight on the moon? Round your answer to the nearest  tenth.

Weight of the astronaut on the moon = 1/6 * 49 kg

Weight of the astronaut on the moon = 8.2 kg

Weight of the astronaut on Mars = 0.38 * 49 kg

Weight of the astronaut on Mars = 18.6 kg

Difference between the astronaut's weight on Mars and her  weight on the moon = 18.6 - 8.2

Difference between the astronaut's weight on Mars and her  weight on the moon = 10.4 kg

Answer:

93750 L

Step-by-step explanation:

P1V1 = P2V2

1.2 atm*125000L = 1.6 atm* V2

V2 = 93750 L

The new volume of the gas is 93750 liters.

Given,

The volume of gas in a container is 125,000 liters.

The pressure is 1.2 atmospheres.

Suppose the temperature remains constant.

The pressure changes to 1.6 atmospheres.

We have to find the new volume of the gas.

The equation is given by:
PV = nRT

Where P is the pressure of the gas.

V is its volume.

n is the number of moles of the gas.

T is its kelvin temperature.

R is the ideal (universal) gas constant.

Let the initial volume and pressure of the gas be [tex]V_{1}[/tex] and [tex]P_{1}[/tex].

The final volume and pressure of the gas be [tex]V_{2}[/tex] and [tex]P_{2}[/tex].

We have,

[tex]V_{1}[/tex] = 125000 litres.

[tex]P_{1}[/tex] = 1.2 atmospheres.

Since temperature remains constant.

[tex]P_{1} V_{1}[/tex] / nR = T and [tex]P_{2} V_{2}[/tex] / nR = T

We can write as:

[tex]P_{1} V_{1}[/tex] / nR = [tex]P_{2} V_{2}[/tex] / nR

[tex]P_{1} V_{1}[/tex]  = [tex]P_{2} V_{2}[/tex]

Putting the values we get,

[tex]P_{1} V_{1}[/tex]  = [tex]P_{2} V_{2}[/tex]

1.2 x 125000 = 1.6 x [tex]V_{2}[/tex]

[tex]V_{2}[/tex] = (1.2 x 125000) / 1.6

   = 93750 litres.

Thus the new volume of the gas is 93750 liters.

Answer:

So a ratio of 8:3 means for every 8 cars that is 3 trucks so we have the number of trucks which is 21 so what i did to find the answer was see how many times 3 went into 21 which is 7 times then you would take the 7 and times it by 8 and get 56 so there are 56 cars.

Step-by-step explanation:

Final answer:

To determine the number of cars, we use the ratio of cars to trucks (8 to 3) with the total number of trucks (21) to find the common multiplier. Multiplying the ratio number for cars (8) by the multiplier (7) gives us 56 cars in the parking lot.

Explanation:

Calculating the Number of Cars in a Parking Lot

To calculate the number of cars in the parking lot when we know the ratio of cars to trucks and the number of trucks, we can set up a proportion. Given that the ratio of cars to trucks is 8 to 3 and there are 21 trucks, we can represent the number of cars as 8x and the number of trucks as 3x, where x is the common multiplier for the ratio. Since we know there are 21 trucks, we can set 3x equal to 21 and solve for x:

3x = 21

Divide both sides of the equation by 3:

x = 21 / 3

x = 7

Now that we have the value of x, we can find the number of cars by multiplying the ratio number for cars (8) by x (7):

Number of cars = 8 x 7

Number of cars = 56

Therefore, there are 56 cars in the parking lot.

Answer:

The offer of 30% off a single item of $ 1000 or more will save most money on these appliances .

Step-by-step explanation:

Given as :

The purchase price = $ 2000

The offering discount = 15 %

Let The price of item after discount = x

So , x = ( $ 2000 ) - ( $ 2000 × 15 % )

Or,  x = ( $ 2000 ) - ( $ 2000 × 0.15 )

Or,  x = ( $ 2000 ) - ( $ 300 )

∴     x =  $ 1700

Now, Again

The purchase price = $ 1000

The offering discount = 30 %

Let The price of item after discount = y

So , y = ( $ 1000 ) - ( $ 1000 × 30 % )

Or,  y = ( $ 1000 ) - ( $ 1000 × 0.3 )

Or,  y = ( $ 1000 ) - ( $ 300 )

∴     y =  $ 700

Now, If we purchase two item at the cost price of $ 700 each , then it will cost as $ 700 × 2 = $ 1400

And for the same number of items at the cost price is $ 1700 after 15 % discount on list price of $ 2000 , So the second offer will save most .

Hence The offer of 30% off a single item of $ 1000 or more will save most money on these appliances . Answer

Answer:

x = -2.

Step-by-step explanation:

(x + 5)^1/2 = (5 - 2x)^1/4

Taking both sides to the power of 4:

(x + 5)^2 = 5 - 2x

x^2 + 10x + 25 = 5 - 2x

x^2  + 12x + 20 = 0

(x + 10(x + 2) = 0

x = -2, -10

Test for extraneous roots.

When x = -10

(-10 + 5)^1/2 = (-5)^1/2 which is not real.

When x = -2

(-2+5)^1/2 = 3 ^1/2

(5 - 2*(-2)) ^1/4 = 9 ^ 1/4 = 3^1/2

so x = -2 is a root.

Answer:

The side lengths of the triangle, in order, are 11 inches, 60 inches, 61 inches.

Step-by-step explanation:

Let the shorter leg be x, the longer leg, y and the hypotenus, z.

y = 16 + 4x

z = 17 + 4x

By Pythagoras rule,

z^2 = x^2 + y^2

(17+4x)^2 = x^2 + (16+4x)^2

that is,

x^2 - 8x - 33 = 0  (A quadratic equation)

By factorising,

(x+3)(x-11)=0

either x = -3 or x = 11.

But length cannot be negative. Hence, -3 is dicarded.

x = 11 inches

y = 16 + 4x = 60 inches

z = 17 + 4x = 61 inches

Final answer:

To find the side lengths of the triangle, assume the shorter leg as 'x' inches. Use the given information about the longer leg and hypotenuse to write equations. Simplify the equation and solve for 'x' to find the side lengths of the triangle.

Explanation:

To find the side lengths of the triangle, let's assume that the shorter leg of the right triangle is 'x' inches.

According to the problem, the longer leg is 16 inches more than four times the shorter leg, so it can be written as '4x + 16' inches.

The hypotenuse is 17 inches more than four times the length of the shorter leg, so it can be written as '4x + 17' inches.

Applying the Pythagorean theorem (a² + b² = c²) to the triangle, we get (x² + (4x + 16)² = (4x + 17)²).

Simplifying the equation and solving for 'x', we find that the shorter leg is 15 inches, the longer leg is 76 inches, and the hypotenuse is 77 inches.

This indicates that the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 4 and d = 3, thus

An explicit formula of an arithmetic sequence:

[tex]a(n)=a(1)+(n-1)d[/tex]

d - common difference

Step-by-step explanation:

I think the answer is 34

To find the number of $32 books purchased, we can set up a system of equations. Solving the system using substitution, we find that the library purchased 34 of the $32 books.

To solve this problem, we can set up a system of equations. Let's call the number of $32 books x and the number of $44 books y. We know that x + y = 54, since the library bought a total of 54 books. We also know that the total cost of the books is $1,968, which can be expressed as 32x + 44y = 1968. Now, we can solve this system of equations to find the value of x.

One way to solve this system is by substitution. Solving the first equation for x, we get x = 54 - y. Plugging this into the second equation, we have 32(54 - y) + 44y = 1968.

Expanding and simplifying, we have 1728 - 32y + 44y = 1968. Combining like terms, we get 12y = 240. Dividing both sides by 12, we find that y = 20. Plugging this back into the first equation x + 20 = 54, we get x = 34.

Therefore, the library purchased 34 of the $32 books.
