Answer:

Step-by-step explanation:

Let's start by figuring out what the new balance is each time the balance changes, and the number of days with that balance. Then we can take the mean of those balances.

Hint #22 / 4

Day of June Transaction amount (in dollars) New balance Days with that balance

111 122312231223 122312231223 10-1=910−1=910, minus, 1, equals, 9

101010 615615615 1223+615=18381223+615=18381223, plus, 615, equals, 1838 15-10=515−10=515, minus, 10, equals, 5

151515 -63−63minus, 63 1838+(-63)=17751838+(−63)=17751838, plus, left parenthesis, minus, 63, right parenthesis, equals, 1775 22-15=722−15=722, minus, 15, equals, 7

222222 -120−120minus, 120 1775+(-120)=16551775+(−120)=16551775, plus, left parenthesis, minus, 120, right parenthesis, equals, 1655 31-22=931−22=931, minus, 22, equals, 9

[Why subtract from 31?]

Hint #33 / 4

To find the mean, we first sum all of the daily balances. Then we divide by 303030, since there are 303030 days in June.

\begin{aligned}&\phantom{=}\dfrac{1223 \times 9 + 1838 \times 5 + 1775 \times 7 + 1655 \times 9}{30} \\\\ &=\dfrac{11{,}007 + 9190 + 12{,}425 + 14{,}895}{30} \\\\ &=\dfrac{47{,}517}{30} \\\\ &=1583.90 \end{aligned}

Answer:

The point (56, 1.75) is on the line.

Step-by-step explanation:

Given two points, we can get the slope (m) as follows:

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

where (x1, y1) and (x2, y2) are the points. Replacing with (8, 0.25) and (16, 0.5):

m = (0.5 - 0.25)/(16 - 8) = 0.03125

The point-slope form of a line is:

y - y1 = m(x - x1)

Replacing with data:

y - 0.25 = 0.03125(x - 8)

To know if point (56, 1.75) is on the line, we have to replace x = 56 in the obtained equation and check y-value, as follows:

y - 0.25 = 0.03125(56 - 8)

y - 0.25 = 1.5

y = 1.5 + 0.25 = 1.75

Then, the point is on the line. This means that there are 56 ounces in 1.75 quarts.

90t-21t=69t

Step-by-step explanation:

4:00pm to 6:00 am is 14 hours. 14 x 1.5 is in fact 21 which means the temperature dropped 21 degrees in those 14 hours.

The equation to represent the temperature after a certain number of hours is t = 90 - 1.5h.

The equation to represent the temperature, t, after h hours can be written as: t = 90 - 1.5h.

Answer:

a. [tex]18x^3 -60x^2 + 33x - 45[/tex]

b. No

Step-by-step explanation:

Given:

(3x-9) and [tex]6x^2-2x+5[/tex]

=> the production of them is:

[tex](3x-9)(6x^2-2x+5)[/tex] , we will use distributive law to solve this To do that. we first multiply  [tex]6x^2-2x+5[/tex] by 3x then by -9. This is done as follows

= [tex]3x (6x^2-2x+5) - 9(6x^2-2x+5)[/tex]  [tex]= (3x * 6x^2-3x * 2x+3x *5) - (9* 6x^2-9* 2x+9* 5)\\\\= (18x^3 -6x^2+ 15x) - (54x^2 - 18x +45)[/tex]

Then Open both brackets

= [tex]18x^3 -6x^2+ 15x -54x^2 + 18x -45[/tex]

After that, we group the same terms

= [tex]18x^3 -(6x^2 +54x^2)+ (15x + 18x) -45[/tex]

= [tex]18x^3 -60x^2 + 33x - 45[/tex]

(b) Is the product of (3x-9) and  [tex]6x^2-2x+5[/tex]  equal to the product of (9x-3) and [tex]6x^2-2x+5[/tex]

No, let find the product of (9x-3) and [tex]6x^2-2x+5[/tex] , we will use distributive law to solve this as the above example.

= (9x-3)[tex](6x^2-2x+5)[/tex]

= [tex]9x (6x^2-2x+5) - 3(6x^2-2x+5)[/tex]

=[tex](9x * 6x^2 - 9x * 2x + 9x *5) - (3* 6x^2 - 3 * 2x + 3* 5)[/tex]

= [tex](54x^3 - 18x^2+ 45x) - (18x^2 - 6x +15)[/tex]

After that, we open the bracket to find the same terms

= [tex]54x^3 - 18x^2+ 45x -18x^2 + 6x -15[/tex]

= [tex]54x^3 - 18x^2 -18x^2 + 45x + 6x -15[/tex]

= [tex]54x^3 - 36x^2 + 51x -15[/tex]  

As you can see [tex]54x^3 - 36x^2 + 51x -15[/tex]   ≠[tex]18x^3 -60x^2 + 33x - 45[/tex]

The value of x in the expression for the angle of the triangle is 12.

The figure in the image is a triangle.

From the image:

Angle 1 = 5x

Angle 2 = 60 degrees

Angle 3 = 60 degrees

Note that, the sum of the interior angle of a triangle equals 180 degrees.

To determine the value of x, add the 3 angles and equate to 180 degrees.

Hence:

5x + 60 + 60 = 180

Collect and add like terms:

5x + 120 = 180

Subtract 120 from both sides:
5x + 120 - 120 = 180 - 120

5x = 180 - 120

5x = 60

x = 60/5

x = 12

Therefore, x has a value of 12.

Answer:

a and c

Step-by-step explanation:

The first one is 3/6 = 50%

The second one is 3/8 = 37.5%

The third one is 2/4 = 50%

The fourth one is 5/8 = 62.5%

The ones with the same percent shaded are the first and third

Answer:

a and c

Step-by-step explanation:

A has 3 out of a total of 6 shaded, and that would be 3/6. 3/6 simplifies into 1/2 which is also 50%. Same with c. 2 out of four pieces are shaded, 2/4. 2/4 becomes 1/2 which is also 50%.

Answer: Each blueberry pie costs $14 and each blackberry pie costs $18.

Step-by-step explanation:

If X is the price of a blueberry pie and Y is the price of a blackberry pie we have that:

3*X + 12*Y = $258

4*X + 3*Y = $110

We have a system of equations, to solve it first we can isolate one of the variables in one of the equations, let's isolate X in the first equation.

3*X = $258 - 12*Y

X = $258/3 - (12*Y)/3 = 86  - 4*Y

now we can replace it in the second equation and get:

4*(86 - 4*Y) + 3*Y = 110

344 - 16Y + 3Y = 110

344 - 13Y = 110

13Y = 344 - 110 = 234

Y = 234/13 = 18

So each blackberry pie costs $18.

And we can replace it in the equation for X and get the value of X.

X = 86 - 4*Y = 86 - 4*18 = 14

So the price of a blueberry pie is $14.

Answer:

the cost each of one blueberry pie is $14

and one blackberry pie is $18

Step by step explanation:

Given that;

Beth sold 3 blueberry pies and 12 blackberry pies for a total of $258.

Ming sold 4 blueberry pies and 3 blackberry pies for a total of $110.

Let x represent the cost of blueberry pies and y the cost of blackberry pie.

3x + 12y = 258 ........1

4x + 3y = 110 ..........2

To solve the simultaneous equations;

Multiply equation 2 by 4, equation 2 becomes;

16x +12y = 440 .......3

Subtract equation 1 from 3;

16x-3x + 12y-12y = 440-258

13x = 182

x = 182/13 = 14

Substituting x=14 to equation 2

4(14) + 3y = 110

3y = 110 - 4(14)

3y = 54

y = 54/3

y = 18

the cost each of one blueberry pie is $14

and one blackberry pie is $18

Answer:

x =15

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh

We know the area=225 and the base= (45-x) and the height =15

Substituting these into the equation

225 = 1/2 (45-x)*15

225 = 15/2 (45-x)

Multiply each side by 2/15

2/15 *225 = 2/15*15/2 (45-x)

30 = 45-x

Subtract 45 from each side

30-45 =45-x-45

-15 = -x

Multiply each side by -1

15=x
