Step-by-step explanation:

if 3 pizzas serve 12 people then 17 pizzas can serve 68 people.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, 3 pizzas serve 12 people.

Assuming y = kx.

12 = 3k.

k = 4.

Now,

68 = 4x.

Answer:

its D give the guy who answered above the brainlist

Step-by-step explanation:

Answer:

Given the domain D = {-1, 0, 3}, the range of f(x) = 3x - 5, is {-8, -5, 4}.

Step-by-step explanation:

To find the range you have to replace the values indicated by the domain in the function (range refers to "y" values of the function).

f(-1) = -8

f(0) = -5

f(3) = 4.

So the range for the given domain is  {-8, -5, 4}.

Answer:  The required range of the given function is {-8, -5, 4}.

Step-by-step explanation:  We are given to find the range of the following function :

[tex]f(x)=3x-5,~~D=\{-1,0,3\}.[/tex]

Since the domain D contains points -1, 0 and 3, so the range will be the following set :

{f(-1), f(0), f(3)}.

We have

[tex]f(-1)=3(-1)-5=-3-5=-8,\\\\f(0)=3\times0-5=-5,\\\\f(3)=3\times3-5=4.[/tex]

Thus, the required range of the given function is {-8, -5, 4}.

Answer: 30,000

Step-by-step explanation: Round 597 to nearest hundred and 52 to nearest ten.

Final answer:

To estimate 597 x 52, round 597 to 600 and 52 to 50, then multiply to get 600 x 50 = 30,000. Therefore, a reasonable estimate is 30,000.

Explanation:

The student has asked for a reasonable estimate for 597 x 52. To provide an estimate, we can round numbers to simplify the multiplication. In this case, we can round 597 to 600 and 52 to 50. Now, let's multiply these rounded numbers.

Therefore, a reasonable estimate for 597 x 52 is 30,000.

Answer is 7

Step-by-step explanation:

you can see in above picture

Step-by-step explanation:

This is a unit conversion problem it seems.

Basically, you're trying to take 25.2 km/h and turn that into m/s.

Let's convert hours to seconds first, so you can sort of see what I mean:

[tex]\frac{25.2km}{1 hour}*\frac{1hour}{60 minutes}*\frac{1minute}{60seconds}[/tex]

So now we've done the first part of the equation, dealing with hours to seconds. See how we now have seconds in the denominator instead of hours? (Keep in mind, we don't want to multiply everything until the very very end!)

Now let's turn kilometers into meters (kilo- means thousand):

[tex]*\frac{1000meters}{1kilometer}[/tex]

Now that we have that, let's multiply out the full equation to get our answer!

[tex]\frac{25.2*1000}{60*60} =7[/tex]

Therefore our answer is the nice and satisfying 7.

Answer:

The cost of one bag of diapers is $11 and the cost of one can of formula is $13

Step-by-step explanation:

Let

x -----> the cost of one bag of diapers

y ----> the cost of one can of formula

we know that

[tex]x+2y=37[/tex] -----> equation A

[tex]2x+5y=87[/tex] ----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

The solution is the point (11,13)

see the attached figure

therefore

The cost of one bag of diapers is $11 and the cost of one can of formula is $13

Final answer:

The cost of one bag of diapers is $11, and the cost of one can of formula is $13, as determined by solving a system of two linear equations that describe Malik's purchases.

Explanation:

The student is presented with a system of linear equations based on the purchases made by Malik at different times. The purchases involve a bag of diapers and cans of formula, with the total amounts spent being provided. This information can be turned into a system of equations to solve for the price of one bag of diapers and the price of one can of formula.

Let D represent the cost of one bag of diapers and F represent the cost of one can of formula. From the given information, we can construct the following equations:

D + 2F = $37 (Equation 1: One bag of diapers and two cans of formula cost $37)

2D + 5F = $87 (Equation 2: Two bags of diapers and five cans of formula cost $87)

Now, let's solve this system of equations using the method of substitution or elimination. For simplicity, let's use the elimination method:

Multiply Equation 1 by 2, so it can be arranged to eliminate D:
2D + 4F = $74

Subtract Equation 1 modified from Equation 2:
(2D + 5F) - (2D + 4F) = $87 - $74,
which simplifies to F = $13.

Now plug the value of F back into Equation 1:
D + 2($13) = $37,
D + $26 = $37,
therefore D = $37 - $26,
D = $11.

Therefore, the cost of a bag of diapers is $11, and the cost of one can of formula is $13.

To confirm if triangle MNP is a dilation of triangle JKL, one must examine the ratios of the corresponding sides. In a dilation, a figure's size changes but its shape and the angles between its sides remain the same, and the lengths of the sides remain proportional. Without the specific measurements, it's not possible to definitively say if MNP is indeed a dilation of JKL.

To determine if triangle MNP is a dilation of triangle JKL, we need to examine the ratios of the corresponding sides. Dilation in mathematics is a transformation that alters the size of a figure without changing its shape or the angles between its sides. In a dilation, the lengths of the sides are proportional.

For example, if triangle MNP has sides that are twice as long as the corresponding sides of triangle JKL, then MNP is a dilation of JKL by a factor of 2.

If the sides of triangle MNP do not maintain the same proportionality with triangle JKL, then triangle MNP is not a dilation of triangle JKL. Therefore, without concrete values or further details, it's difficult to definitively answer whether MNP is a dilation of JKL.

Answer:

Diapers costs $11 and formula is $13.

Step-by-step explanation:

Let's name diapers as A and formula as B.

Simply the equations:

1A + 2B = $37(1)

2A + 5B = $87(2)

Clear D from one equation.

A = $37 - 2B(1)

Replace D into the other equation.

2*($37 - 2B) + 5B = $87(2)

$74 - 4B + 5B = $87

$74 + B = $87

B = $87 - $74 = $13

Find A, now knowing B.

A = $37 - 2($13)

A = $37 - $26 = $11

Answer:

Cost of a bag of diapers is $11 and cost of one can of formula is $13.

Step-by-step explanation:

Let cost of each diaper = $D and cost of each cans of formula = $C

Malik shops a bag of diapers and 2 cans of formula.

He spends total of $37.

So the equation will be

D + 2C = 37 -------(1)

Next week he stops and buys 2 bags of diapers and 5 cans of formula.

He spends total $87.

Equation for this purchase will be

2D + 5C = 87 ----------(2)

Multiply equation (1) by 2 and subtract it from equation (2).

2(D + 2C) - (2D + 5C) = 2×37 - 87

2D + 4C - 2D - 5C = 74 - 87

-C = - 13

C = 13

From equation (1)

D + 2×13 = 37

D + 26 = 37

D = 37 - 26

D = 11

Therefore, cost of a bag of diapers is $11 and cost of one can of formula is $13.

Answer:

x = 9

Step-by-step explanation:

The trick here is knowing that JKM and MKL are equal, which means MKL is equal to JKL/2. From that knowledge, we can solve.

MKL = JKL/2

5x + 1 = 46

5x = 45

x = 9

The value of the x is 9 if KM bisects JKL, m JKL = 92, and MKL = (5x+1).

Since KM bisects JKL, it divides the angle JKL into two congruent angles. Therefore, angle MKL is equal to angle JKL divided by 2.

Given that angle JKL is 92 degrees, we can find the value of x by setting up the following equation:

5x + 1 = 92/2

First, we simplify the right side of the equation:

92/2 = 46

Now, we can solve for x:

5x + 1 = 46

5x = 46 - 1

5x = 45

x = 45/5

x = 9

Therefore, the value of x is 9.
