Franco made number of muffins = a dozen

A dozen muffins = 12 muffins

Number of muffins were burned = 2

Remaining muffins = 12 - 2 = 10

Franco served 7 of the remaining non-burned muffins,

Fraction of muffins served = [tex]\frac{7}{10}[/tex]

Remaining muffins = 3

Fraction of remaining muffins = [tex]\frac{3}{10}[/tex]

Fraction of remaining non-burned muffins we can get from,

[tex]\frac{10}{10}-\frac{7}{10}=\frac{3}{10}[/tex]

Option B is the correct equation.

Answer:

[tex]3x^2-10x+8=(x-x_1)(x-x_2)=(x-2)(x-\frac{4}{3})[/tex]

Step-by-step explanation:

The general form of a quadratic polynomial is given by:

[tex]ax^2+bx+c[/tex]    (1)

You have the following polynomial:

[tex]3x^2-10x+8[/tex]    (2)

In order to complete the factorization you can use the quadratic formula, to obtain the roost of the polynomial. The quadratic formula is given by:

[tex]x_{1,2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]    (3)

By comparing the equation (1) with the equation (2) you obtain:

a = 3

b = -10

c = 8

Then, you replace these values in the equation (3):

[tex]x_{1,2}=\frac{-(-10)\pm \sqrt{(-10)^2-4(3)(8)}}{2(3)}\\\\x_{1,2}=\frac{10\pm2}{6}\\\\x_1=2\\\\x_2=\frac{4}{3}[/tex]

Then, the factorization of the polynomial is:

[tex]3x^2-10x+8=(x-x_1)(x-x_2)=(x-2)(x-\frac{4}{3})[/tex]

Answer:

B.

Step-by-step explanation:

[tex](\frac{x}{y} )^{a} = \frac{x^{a}}{y^{a}}[/tex]

Answer: 35 / 66

Step-by-step explanation:

Given the data bekow:

Outcome : - - - 1 - - - 2 - - - 3 - - - 4 - - - 5 - - - 6

Frequency : - 12 - - - 9 - - - 11 - - 8 - - - 12 - - - 14

What is the experimental probability of spinning an odd

P(spinning an odd) = (number of occurrence of an event / number of trials)

Odd outcomes = 1, 3, 5

Frequency of 1 = 12

Frequency of 3 = 11

Frequency of 5 = 12

Number of occurrences of odd = (12 + 11 + 12) = 35

Number of trials = 66

Therefore,

P(spinning an odd) = 35 / 66

Answer:

[tex]\frac{4}{9}[/tex]

Step-by-step explanation:

So first rewrite the inside of the parentheses as improper fractions:

[tex]\frac{8}{9}[/tex] ÷ [tex](\frac{25}{4}*\frac{16}{5}-18)[/tex]

Now simplify the inside:

[tex]\frac{8}{9}[/tex] ÷ 2

Which is:

[tex]\frac{8}{18}=\frac{4}{9}[/tex]

Answer:

x=1, y = -3

Step-by-step explanation:

2x -y=-11

6x + y = 3​

Add the two equations together

2x -y=-11

6x + y = 3​

--------------------

8x  = 8

Divide by 8

8x/8 = 8/8

x= 1

Now find y

6x+y = 3

6(1) +y = 3

6+y =3

Subtract 6 from each side

6+y-6 = 3-6

y = -3

Answer:

x = 50

Step-by-step explanation:

You are correct.

x + m<PQS + m<PSQ = 180

m<PQS = m<QRT = 70

m<QST + m<PSQ = 180

120 + m<PSQ = 180

m<PSQ = 60

x + 70 + 60 = 180

x + 130 = 180

x = 50

Great job!

Answer:

Correct option: third one -> 12

Step-by-step explanation:

In a polygon with 'n' vertex, we can trace diagonals from one vertex to all vertices, except to the vertex chosen and the two adjacent vertices (because we would have sides and not diagonals), so we would have 'n - 3' diagonals.

If we have a polygon with 15 vertex, the number of diagonals from one vertex is 15 - 3 = 12.

Correct option: third one

Answer:

a = 1

Step-by-step explanation:

The given equation is:

=> 5x+y = 8

Also,

Point = (x,y) = (a,3)

So, x = a , y = 3

Putting this in the above equation

=> 5(a)+3 = 8

=> 5a = 8-3

=> 5a = 5

Dividing both sides by 5

=> a = 1

IR=√((6-1)²+(3-1)²)=√(25+4)=√29

PI=6+1=7

PE=3+2=5

Perimeter=√58+5+6+√29+7+5=23+√58+√29≈37.68 units

Answer:

3pi/4 =x       and 5pi/4 =x

Step-by-step explanation:

cos x + sqrt(2) = - cos x

subtract cos x from each side

cos x - cosx + sqrt(2) = - cos x - cos x

sqrt(2) = -2 cos x

Divide each side by -2

-sqrt(2) / 2 =-2 cos (x) /-2

-sqrt(2) /2 =cos (x)

Take the inverse cos of each side

cos(-1)(-sqrt(2) /2) =cos^-1(cos (x))

3pi/4 =x       and 5pi/4 =x

Answer:

Here's your answer:

3pi/4 =x       and 5pi/4 =x

cos x + sqrt(2) = - cos x

subtract cos x from each side

cos x - cosx + sqrt(2) = - cos x - cos x

sqrt(2) = -2 cos x

Divide each side by -2

-sqrt(2) / 2 =-2 cos (x) /-2

-sqrt(2) /2 =cos (x)

Take the inverse cos of each side

cos(-1)(-sqrt(2) /2) =cos^-1(cos (x))

3pi/4 =x       and 5pi/4 =x

Answer:

There are £61.50 in 992 rubles

Step-by-step explanation:

Here, we shall be doing some currency conversions.

Now,

£31 = 500 rubles

Then;

£x = 992 rubles

To get c, what we do is simply cross multiply

£x * 500 rubles = £31 * 992 rubles

£x = (£31 * 992 rubles)/500 rubles

£x = £61.504

which is £61.50 to two decimal places

The graph shows that for every hour the earnings are $!8.

Option D is the correct answer.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

Some of the coordinates from the graph are:

(1, 18), (2, 36), and (3, 54)

Now,

The rate of change between (1, 18), and (2, 36).

Slope = (36 - 18) / (2 - 1) = 18

The rate of change between (2, 36), and (3, 54).

Slope = (54 - 36) / (3 - 2) = 18

This means,

That for every hour there is an earning of $18.

Thus,

The graph shows that for every hour the earnings are $!8.

Answer:

Step-by-step explanation:

A half-kilo jar is 500 grams, so a 400 g can would be 4/5 the weight. 4/5 of 2.5 g of fat would be 2.0 g of fat. The 400 g can has 2.1 g, so has more fat, proportionally, than its weight would suggest.

The fat is not proportional to the can sized. The 400 g can has more fat, proportionally.
