Amara needs 4545 kilograms of meat to feed her 22 pet dragons each day. Each pet dragon eats the same amount of meat. How many kilograms of meat does Amara need to feed 44 pet dragons each day?

You would need 12 gallons of paint A. You can find this answer by finding what 60% of 20 is, and do that by multiplying 20 • (0.6). This is what gives you 12. Following that, you’ll need 3 gallons of C, and 5 gallons of B.

The values less than 6,766 are one fourth x 6,766 and one half x 6,766 (A and C options are correct)

Answer:

y = [tex]\frac{1}{2}[/tex] x + 7

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = [tex]\frac{1}{2}[/tex], hence

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

to find c substitute (4, 9) into the partial equation

9 = 2 + c ⇒ c = 9 - 2 = 7

y = [tex]\frac{1}{2}[/tex] x + 7 ← equation in slope-intercept form

Answer:

Brand A = 21 heart-rate watches.

Brand B = 13 heart-rate watches.

Step-by-step explanation:

Let A be the number of Brand A heart watches and B be the number of Brand B heart watches.

We have been given that a nonprofit community health organization purchased 34 ​heart-rate watches for use at a wellness center.

We can represent this information in an equation as:

[tex]A+B=34...(1)[/tex]

We have been given that in a certain​ year, brand A of​ heart-rate watch cost ​$39.99 and brand B cost ​$59.99 and the organization spent ​$1619.66 for the​ watches.

We can represent this information in an equation as:

[tex]39.99*A+59.99*B=1619.66...(2)[/tex]

We will use substitution method to solve our system of equations.

From equation (1) we will get,

[tex]A=34-B[/tex]

Substituting [tex]A=34-B[/tex] in equation(2) we will get,

[tex]39.99*(34-B)+59.99*B=1619.66[/tex]

[tex]1359.66-39.99*B+59.99*B=1619.66[/tex]

[tex]-39.99*B+59.99*B=1619.66-1359.66[/tex]

[tex]20*B=260[/tex]

[tex]B=\frac{260}{20}[/tex]

[tex]B=13[/tex]

Therefore, the organisation purchased 13 heart-rate watches of brand B.

Now let us substitute B=13 in equation (1).

[tex]A+13=34[/tex]

[tex]A+13-13=34-13[/tex]

[tex]A=21[/tex]

Therefore, the organisation purchased 21 heart-rate watches of brand A.

Answer:

42:53 would be the answer

Step-by-step explanation:

In a ski club fundraiser, the ratio of Italian hoagies sold to the total number of hoagies sold, when the numbers of Italian and roast beef hoagies are 42 and 53 respectively, is 42:95.

The student is asking for the ratio of Italian hoagies sold to the total number of hoagies sold at a ski club fundraiser. To calculate this ratio, one must add the number of Italian hoagies to the number of roast beef hoagies to determine the total hoagies sold. In this case, 42 Italian hoagies were sold, and 53 roast beef hoagies were sold, yielding a total of 95 hoagies sold. Thus, the ratio of Italian hoagies sold to total hoagies sold is 42:95. In ratio terms, this expresses that for every 42 Italian hoagies sold, there were 95 total hoagies sold.

Answer:

y-4 = 3 (x-2)

Step-by-step explanation:

To find the slope of a line

slope = (y2-y1)/(x2-x1)

slope = (1-4)/(2-3)

         = -3/-1

         =3

Now we use the point slope form for a line

y-y1 = m(x-x1)

y-4 = 3 (x-2)

Answer:

y-4 = 3 (x-2)

y=-3x+10

Answer:

640 kilocalories are there in this 2-cup serving.

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal.

As per the given statement: There are 1600 kilocalories in 5 cups of dog food that mike gives his adult dog. Mike gives his puppy 2 cups of the same dog food.

Let x kilocalories are there in 2-cup serving.

then, by definition of proportion;

[tex]\frac{1600}{5} =\frac{x}{2}[/tex]

Multiply both sides by 2 we get;

[tex]x = \frac{1600}{5} \times 2[/tex]

Simplify:

[tex]x = 320 \times 2 = 640 kilocalories[/tex]

Therefore, 640 kilocalories are there in this 2-cup serving.

Answer:

1 and 3/4 days are equal to 42 hours

Step-by-step explanation:

42 hours = (42 hours) (1 day / 24 hours)

42 hours = 42/24 days

Simplyfing the fraction: Dividing the numerator and denominator by 6:

42 hours = (42/6) /  (24/6) days

42 hours = 7/4 days

42 hours = (4+3)/4 days

42 hours = (4/4+3/4) days

42 hours = 1 3/4 days

To determine how many days are equal to 42 hours, you divide 42 by 24 which results in 1.75. Therefore, 42 hours is equivalent to 1 and 3/4 days.

In this mathematics problem, we are asked to convert 42 hours into a measurement of days. To begin with, we know that 1 day equals 24 hours. Therefore, to convert 42 hours into days we will divide 42 by 24.

The result of this division is 1.75. In terms of a day fraction, this value represents 1 and 3/4 days. As such, we can say that 42 hours is equivalent to 1 and 3/4 days.

Immediately, we can factor an x out of each term to simplify the polynomial.

x(x^2 + 2x - 24)

In doing this, we know the first zero will be x = 0.

Using the AC method, we can find the next two zeros.

x(x - 4)(x + 6)

The zeros of the polynomial function f(x) = x^3 + 2x^2 -24x are x = -6, 0, and 4.

The question requires finding the zeros of the polynomial function f(x) = x^3 + 2x^2 -24x. The zeros of this function can be found by setting the function equal to zero and solving for x. So, we have 0 = x^3 + 2x^2 - 24x. All terms have an 'x', so we can factor out 'x' to give: 0 = x (x^2 + 2x - 24). The quadratic formula (which is used for expressions of the form ax^2 + bx + c = 0) to solve x^2 + 2x - 24 = 0, we get x = -6 and x = 4. Therefore, the zeros of the function are x = -6, 0, and 4.

Radical form is the form of a equation in which the number or variable is written under some power of the root. The 15 to the 1/3 power in radical form is [tex]\sqrt[3]{15}[/tex].

15 to the 1/3 power is the 1/3 power of the number fifteen and it can be expressed as,

[tex]=(15)^{\dfrac{1}{3}[/tex]

This number has to be written in the radical form.

Radical form is the form of a equation in which the number or variable is written under some power of the root.

When a fractional exponents of the number is given the numerator becomes the power and the denominator becomes the root. Let [tex]x^{\dfrac{a}{b}[/tex] is a number with fractional exponents where a and b are the real and positive integer, then a becomes the power and the b becomes the root of the number x.

[tex]x^{\dfrac{a}{b} }=\sqrt[b]{x^a}[/tex]

Answer:

g(f(x)) = x

Step-by-step explanation:

You are given f(x) = -4x - 1 and g(x) = [tex]\frac{x+1}{-4}[/tex]. Keep in mind that f(x) or g(x) is the same as a y = equation, but two separate equations.

You are trying to find g(f(x)), which means that you will use f(x) and substitute this value into the x value in the equation of g(x).

It will look like: g(-4x - 1) = [tex]\frac{x+1}{-4}[/tex]

[tex]\frac{(-4x-1)+1}{-4}[/tex]

Now evaluate the expression to solve the problem. Start by combining like terms.

[tex]\frac{(-4x)}{-4}[/tex]

You are left with -4x/-4. We can simplify this even further by dividing both sides of the fraction by -4/-4. The -4's cancel out and become 1's, so you are left with:

[tex]x[/tex]

Answer:

Step-by-step explanation:

g(f(x)) means that wherever you see an x in g(x) you put f(x) in it's place. Read that sentence a couple of times until it makes sense.

g(x) = (x + 1)/-4

g(f(x)) = (f(x) + 1) / - 4           Now wherever you see f(x), put in -4x - 1

g(f(x)) = [(-4x - 1) + 1] / - 4     Remove ( )

g(f(x)) = [-4x - 1 + 1 ] / - 4

g(f(x)) = [-4x] / - 4                 Do the division

g(f(x)) = x

The value of x can be any real number because raising 1 to any exponent will always result in 1.

The question needs us to solve for x in the equation [tex](6 to the 0 power)^x[/tex]= 1. We know that any non-zero number raised to the 0 power is 1 (e.g.,[tex]10^0[/tex] = 1). Thus, 6 to the 0 power is 1 regardless of the value of 6. From this, we have[tex]1^x[/tex], which is still 1 for any value of x because 1 raised to any power is always 1. Hence, the equation remains true for any real number value of x.
