Answer:

8/5 oz

Step-by-step explanation:

The problem is saying that there are 8 ounces of cheese and 5 bowls of spaghetti you need to divide the cheese over. As you need an equal amount of cheese in each bowl, you have to divide 8 ounces by the number of bowls, which is 5. Thus, you would do 8 divided by 5, which we just say is 8/5. Therefore, your answer is 8/5 ounces of cheese (or simplified to 1 3/5).

Step-by-step explanation:

Given :-

And we need to solve the equation using Substituting method . So on taking the first equation ,

[tex]\rm\implies x + 3y = 3 \\\\\rm\implies x = 3 - 3y [/tex]

Put this value in (ii) :-

[tex]\rm\implies 3y - 2x = 12 \\\\\rm\implies 3y - 2(3-3y)=12\\\\\rm\implies 3y -6-6y = 12 \\\\\rm\implies -3y = 18 \\\\\rm\implies y = -6 [/tex]

Put this Value in (I) :-

[tex]\\\\\rm\implies x = 3-3*-6 \\\\\rm\implies x = 3+18 \\\\\rm\implies x = 21 [/tex]

Hence the Value of x is 21 and y is (-6) .

Answer:

x = -3

y = 2

Step-by-step explanation:

Ok this is a long one but bear with me lol, i promise i will make it easy to understand, performing one step at a time.

So we are given 2 equations right? We can take any of these one equation and isolate any one variable, either x or y, I will take the first equation and isolate x from it cuz it's the easiest way;

=> x + 3y = 3

=> x = -3y + 3 (Let's pretend this is not an equation for x but a "value")

Now that we have the x isolated from first equation, we can substitute x "value" in for the x in second equation. To solve for y;

=> 3y - 2 (-3y + 3) = 12

=> 3y + 6y - 6 = 12

=> 9y - 6 = 12

=> 9y = 12 + 6

=> 9y = 18

=> y = 18/9

=> y = 2

At this point we are almost done with the question! So since we got a real value for one of our variable (which in this case is y-value), we can substitute that in any of the given equation, We can also use the equation where in we isolated "x", so I'll use that cuz it's gonna require less steps, to find the real x-value:

=> The equation we found out up there is: x = -3y + 3

=> Now just simply substitute the y-value we figured in the equation above:

=> x = -3y + 3

=> x = -3(2) + 3

=> x = -6 + 3

=> x = -3

Ayee we did it lol so the final answer would be:

x = -3

y = 2

I really hope this made sense, and that it helps!

Answer:

(4, 11) is one ordered pair  and (-4, 27) is the other ordered pair

Step-by-step explanation:

(1)  f(x) = x^2 - 2x + 3             (2)    f(x) = -2x + 19

-2x + 19 = x^2 - 2x + 3

x^2 - 16 = 0

(x - 4)(x + 4) = 0

x = 4   or    x = -4                                  -2(4) + 19 = 11

                                                             -2(-4) + 19 = 27

So, when x = 4, y = 11                   and when x = -4, y = 27

(4, 11) is one ordered pair              and (-4, 27) is the other ordered pair

Answer:

The experimental probability of tossing heads is [tex]\frac{2}{5}[/tex].

Step-by-step explanation:

The experimental probability is the probability that is determined on the basis of the results of an experiment repeated many times. Since Vernon tossed 8 heads during his 20 experiments, the experimental probability of tossing heads is [tex]\frac{8}{20}[/tex] or [tex]\frac{2}{5}[/tex].

Answer:

10 cm

Step-by-step explanation:

the can is shaped like a cylinder

first step is to find the radius and then multiply the figure by 2

volume of a cylinder = nr^2h

n = 22/7

r = radius

903 = 11.5 x r^2 x 3.14

r^2 = 903 / (3.14 x 11.5)

r = 5 cm

diameter = 10cm

The place where the line crosses the y-intercept.

Answer:

?

Step-by-step explanation:

Step-by-step explanation:

y = x^2 + 2x - 15

To find the x-intercepts, factor out the right side:

y = x^2 + 2x - 15

= (x + 5)(x - 3)

This means that the x-intercepts are at (-5, 0) and (3, 0).

Method 1:

The x-coordinate of the vertex of a parabola is given by the following:

x = -b/2a, where a = 1 and b = 2

= -(2/(2×1))

= -1

Using this value of x gives y = -16

Therefore, the coordinates of the vertex is (-1, -16).

Method 2:

We can find the x-coordinate of the vertex by taking the derivative of y and equating it to zero:

y' = 2x + 2 = 0 ---> x = -1

Using this value of x into our equation, we get y = -16.

Therefore,

vertex: (-1, -16)

Answer:

56

Step-by-step explanation:

1. first order the numbers from least to greatest (26, 39, 42, 56, 64, 71, 85)

2.  Then count how many numbers you have and divide it by 2. We have 7 numbers, so we’ll divide by 2 and round up because 7 is an odd number. (7 divided by 2 =3.5, rounded up is 4.)

3. Now we know the position of the number is this 4th spot, so the median is 56.

The median of the given set of numbers is 56.

What is the median of data?

The median is defined as the value range. To get it, arrange the numbers in ascending order from smallest to largest, then hide one number on either end until you reach the center.

The given set of data as:

{85, 42, 64, 71, 39, 56, 26}

Let's arrange the given numbers in ascending order: 26, 39, 42, 56, 64, 71, 85.

Since we have 7 numbers, which is an odd count, the median is the middle number.

In this case, the middle number is the fourth number, which is 56.

Therefore, the median of the given set of numbers is 56.

Answer:

h=8

Step-by-step explanation:

a²+b²=c²

a=A

b=12

c=13

therefore substitute

A²+(12)²=(13)²

A²=13²-12²

A²=25

A=5

h=3+A

h=3+5

h=8

Answer:

8 ft

Step-by-step explanation:

since it is a right angled triangle and you have 2 side lengths, we use the pythagoras theorem here.

a² + b² = c²

the c² is always your hypotenuse (longest side of the triangle, also opposite to the right angles)

*the b and a doesnt matter which order you put it in*

so; (sub in the numbers to the formula)

a² + 12² = 13²

(rearrange - like terms together)

a² = 13² - 12²

(calculate it)

a² = 25

(simplify it - get rid of the ² on the a)

a = √25

(solve)

a = 5

so, we know that a = 5 and we know that we have an additional 3

5 + 3 = 8

Answer:

[tex]E=2.15\times 10^{-4}\ J[/tex]

Step-by-step explanation:

Given that,

The capacitance of the capacitor, [tex]C=2.2\times 10^{-6}\ F[/tex]

Voltage of the power supply, V = 14 V

We need to find the energy stored in the capacitor.

The formula for the stored energy in the capacitor is given by :

[tex]E=\dfrac{1}{2}CV^2[/tex]

Put all the values,

[tex]E=\dfrac{1}{2}\times 2.2\times 10^{-6}\times 14^2\\\\E=2.15\times 10^{-4}\ J[/tex]

So, [tex]2.15\times 10^{-4}\ J[/tex] of energy is stored in the capacitor.

Answer:

∑j=15(5j−12)

Step-by-step explanation:

For j = 1 up to j = 5

j = 1

(5j - 12) = (5(1) - 12) = 5 - 12 = - 7

j = 2

(5j - 12) = (5(2) - 12) = 10 - 12 = - 2

j = 3

(5j - 12) = (5(3) - 12) = 15 - 12 = 3

j = 4

(5j - 12) = (5(4) - 12) = 20 - 12 = 8

j = 5

(5j - 12) = (5(5) - 12) = 25 - 12 = 13

(-7 + (-2) + 3 + 8 + 13)
