The manager at a pizza restaurant keeps track of the number of large pizzas and small pizzas sold each day and the total money received. On Monday, a total of 63 pizzas were sold, and the money collected was $989. If large pizzas are sold for $18 and small pizzas are sold for $13, how many large pizzas and small pizzas were sold?
34x18 = 612
29x13=377
377+612 = 989
34 large 29 small
The number of large pizza is 34 and the number of small pizza is 29.
How to find the number of small and large pizza in the problem given ?It is given that a total of 63 pizzas were sold.
Also, the money collected was $989.
Moreover, large pizzas are sold for $18 and small pizzas are sold for $13.
Let the number of large pizzas be x and the number of smaller pizzas be y.
From the problem statement , x + y = 63.
The total cost for large pizza is $18x and the total cost for small pizza is $13y . Now this sum is the total money collected.
∴ 18x + 13y = 989.
We have two equations ,
x + y = 63 and 18x + 13y = 989.
Substituting the value of x from first and putting it to second,
⇒ 1134 - 18y + 13y = 989.
⇒ -5y = -145
∴ y = 29 .
Putting value of y in the first equation, we have x = 34.
Therefore the number of large pizza is 34 and the number of small pizza is 29.

Ayodele received a raise in her hourly pay, from $24.50 to $25.48. Find the percent change.
Answer:
4%
Step-by-step explanation:
The raise in her hourly pay is
$25.48-$24.50 =$0.98
Cross multiplying (rule of three)
24.50------100%
0.98--------x%
and so, x= 0.98*100/24.5 = 4%
Answer: The required percent change is 4%.
Step-by-step explanation: Given that Ayodele received a raise in her hourly pay, from $24.50 to $25.48.
We are to find the percent change.
The percent change is given by
[tex]p=\dfrac{\textup{increse in the amount}}{\textup{original amount}}\times100\%.[/tex]
In the given situation, we have
[tex]\textup{increase in the amount}=\$(25.48-24.50)=\$0.98.[/tex]
Therefore, the percent change is given by
[tex]p=\dfrac{0.98}{24.50}\times100\%=\dfrac{98}{24.50}\%=4\%.[/tex]
Thus, the required percent change is 4%.
Solve for x.
[tex]\frac{2x}{9}[/tex] = -65
x = -292 [tex]\frac{1}{2}[/tex]
x = -14 [tex]\frac{4}{9}[/tex]
x = 292 [tex]\frac{1}{2}[/tex]
The correct answer is:
[tex]x = -292 \frac{1}{2}[/tex]
Let's solve the equation step-by-step to find the value of [tex]x[/tex]:
The given equation is:
[tex]\frac{2x}{9} = -65[/tex]
First, we need to isolate [tex]x[/tex]. We can do this by multiplying both sides of the equation by 9, which is the denominator on the left side:
[tex]9 \times \frac{2x}{9} = 9 \times -65[/tex]
This simplifies to:
[tex]2x = -585[/tex]
Next, we need to get [tex]x[/tex] by itself, so we divide both sides by 2:
[tex]\frac{2x}{2} = \frac{-585}{2}[/tex]
This simplifies to:
[tex]x = -292.5[/tex]
So, [tex]x = -292.5[/tex] or [tex]x = -292 \frac{1}{2}[/tex].

P=hx/5. Pls help
Answer:
x = [tex]\frac{5P}{h}[/tex]
Step-by-step explanation:
Given
P = [tex]\frac{hx}{5}[/tex] ( multiply both sides by 5 )
5P = hx ( divide both sides by h )
x = [tex]\frac{5P}{h}[/tex]
The given equation P = hx/5 can be rearranged to x = 5P/h, by first multiplying both sides by 5, and then dividing both sides by h
Explanation:The current equation P = hx/5 can be rearranged to isolate x by employing algebraic steps. We first need to get rid of the division by 5 from the right side of the equation to leave hx isolated. We achieve this by performing the opposite operation, that is multiplication on both sides of the equation by 5:
5P = 5*(hx/5)
This simplifies to 5P = hx.
Finally, to obtain x by itself, we want to get rid of the multiplication by h in the equation. We do so by dividing both sides of the equation by h:
(5P)/h = hx/h
Which simplifies to: x = 5P/h
This is the final rearranged equation with x isolated.

Where should the classmate plot point
D so that the quadrilateral formed has
perpendicular sides?
Answer:
D(-1,0)
Step-by-step explanation:
Plot points A(-3, 2), B(-1, 4), and C(1, 2) on the coordinate plane (see attached diagram).
Two sides AB and BC are of equal length and are perpendicular, because
[tex]AB=\sqrt{(-3-(-1))^2+(2-4)^2}=\sart{(-2)^2+(-2)^2}=\sqrt{4+4}=2\sqrt{2}\ units\\ \\BC=\sqrt{(-1-1)^2+(4-2)^2}=\sart{(-2)^2+2^2}=\sqrt{4+4}=2\sqrt{2}\ units\\ \\\text{Slope AB}=\dfrac{4-2}{-1-(-3)}=\dfrac{2}{2}=1\\ \\\text{Slope BC}=\dfrac{2-4}{1-(-1)}=\dfrac{-2}{2}=-1\\ \\\text{Slope AB}\cdot \text{Slope BC}=1\cdot (-1)=-1\Rightarrow \text{lines AB and BC are perpendicular}[/tex]
If the quadrilateral ABCD has all sides perpendicular, then ABCD is a square. The diagonals of the square bisects each other. Find the coordinates of the point of intersection of these diagonals. This is the midpoint of segment AC:
[tex]x=\dfrac{-3+1}{2}=-1\\ \\y=\dfrac{2+2}{2}=2[/tex]
If point O(-1,2) is the point of intersection of diagonals, then it is the midpoint of the diagonal BD. Find coordinates of point D:
[tex]x_O=\dfrac{x_B+x_D}{2}\Rightarrow -1=\dfrac{-1+x_D}{2},\ -1+x_D=-2,\ x_D=-1\\ \\y_O=\dfrac{y_B+y_D}{2}\Rightarrow 2=\dfrac{4+y_D}{2}, 4+y_D=4,\ y_D=0[/tex]

10. The values of x and y vary directly, and
when x = 48, y = 36. Find the value of x when
y = 18.
Answer:the answer is 24
Step-by-step explanation:
Because when 18 is the half of 36 so 24 is the half of 48
Given x and y vary directly with constant ratio 1.33, the value of x when y equals 18 is 23.94.
Explanation:The subject question deals with direct variation, a concept in Mathematics. When two variables vary directly, a change in one variable results in a proportionate change in the other variable. If x and y vary directly, it means the ratio of x to y is constant.
From the problem, x = 48 when y = 36. Therefore, the ratio of x to y is 48/36 = 1.33.
To find the value of x when y = 18, simply multiply the constant ratio (1.33) by the new value of y.
So, x = 1.33 * 18 = 23.94

Which diagram shows AABC rotated 120° counterclockwise about B?
Answer:
second one diagram rotated 120
In a 120° counterclockwise rotation about point B, diagram AABC would shift each point along a circular path 120° in a counterclockwise direction around point B. The positions of points A and C would change, while point B would stay as it is. The correct diagram would reflect these changes.
Explanation:Without a specific diagram to refer to, I can provide only a general explanation of how to determine the diagram that represents AABC rotated 120° counterclockwise about point B.
Rotations in a plane are performed counterclockwise with a positive degree measure. So, a 120° counterclockwise rotation about a fixed point B would take every point on triangle AABC and shift it along a circular path 120° in a counterclockwise direction around point B. The result would be a new triangle A'B'C'. If point B is the origin of rotation, it would remain unchanged. However, points A and C would change their positions after the rotation.
To determine the correct diagram, you would look for a triangle that has been shifted around point B in a counterclockwise direction with positions of points A and C reflecting a 120° rotation.

The real interest rate of a savings account that has a nominal interest rate of 1% when the rate of inflation is 1% is B.) 0%
How to find the real interest rate ?The real interest rate is the interest rate that is adjusted for inflation. It is calculated by subtracting the inflation rate from the nominal interest rate. In this case, the nominal interest rate is 1% and the inflation rate is also 1%.
So, the real interest rate is:
= 1% - 1%
= 0%
In other words, if you deposit $100 in a savings account with a nominal interest rate of 1%, you will earn $1 in interest after one year. However, because inflation is also 1%, the purchasing power of your $100 will decrease by $1. So, the real value of your savings will not change.
