Mr. O'Hara ordered a total of 8 pizzas to celebrate the end of the soccer season. If Mr. O'Hara ordered 2 more cheese pizzas than pepperoni pizzas, how many of each type did he order?
Answer:
5 cheese pizzas and 3 pepperoni pizzas
Step-by-step explanation:
The correct way to solve this is to formulate two related equations since there are two unknowns...the number or pepperoni pizzas and the number of cheese pizzas.
To make is easier to write...we will call pepperoni pizzas p and cheese pizzas c.
we know that the total number of pizzas is 8 so
p + c = 8
Pepperoni (p) pizzas plus Cheese (c) pizzas is 8
We also know that
c = p + 2
Cheese (c) pizzas is equal to Pepperoni (p) pizzas plus 2...there are two more cheese pizzas than pepperoni pizzas.
if we use this second equation to replace for c in the first equation we get
p + (p +2) = 8
c and (p + 2) are the same value so we can use either in place of the other. I am using the parentheses just to group p plus 2 together to hopefully make it clear what I did.
If we now add the two p together we get 2p so the equation is now
2p + 2 = 8
If we now subtract 2 from both sides we maintain the equality because we are making the same change to both sides
2p + 2 - 2 = 8 - 2
2 minus 2 is zero and 8 minus 2 is 6
2p = 6
Now if we divide both sides by 2 we get the following
p = 3
This is because 2p divided by 2 is 1p or just p and 6 divided by 2 is 3.
This tells us that there are 3 pepperoni pizzas as p stands for pepperoni here
Now if we go back to either equation and substitute the value 3 for the variable p we can solve for c or cheese pizzas
c = p + 2 was one equation so
c = 3 + 2
or
c = 5
if we use the other equation, p + c = 8 we get
3 + c = 8
We can subtract 3 from both sides and maintain the equality
3 - 3 + c = 8 - 3
3 minus 3 is zero and 8 minus 3 is 5 so again
c = 5
There are 3 pepperoni pizzas and 5 cheese pizzas
At Cindy's birthday each guest will get one-third of a medium sized pizza. There will be 12 people at the party, including Cindy. How many pizza's does her mom need? awnser is 6
Answer: 4 pizzas
Step-by-step explanation:
There are to be 12 people at the party.
Each person is expected to take 1/3 of a pizza.
The total number of pizza needed is therefore:
= No. of people * quantity of pizza
= 12 * 1/3
= 4 pizzas
Note: Answer would be 6 if each guest wanted 1/2 of a pizza.

Answer:
a + 17 = 35
Step-by-step explanation:
The reason why that expression is correct is because there are two sides of a rectange and one sides value is 17. In total the sides make 35 so how will you evaluate the answer
a + 17 = 35 ( something + 17 = 35)
When you add them they make 35 not when you substract them

Amaya went to the pet store. She bought x fish for $3.50 each. She bought fish food for $7.00, and a fish bowl for $12.75. Determine how much Amaya spent at the pet store if she bought 4 fish.
Answer:
$93
Step-by-step explanation:
Amaya went to the pet store. She bought x fish for $3.50 each. She bought fish food for $7.00, and a fish bowl for $12.75. Determine how much Amaya spent at the pet store if she bought 4 fish.
Step 1
We calculate the total amount spent on 1 fish
= Cost of fish + Cost of food + Cost if bowl
= $3.50 + $7.00 + $12.75
= $23.25
Step 2
The total amount spent on 4 fishes is calculated as
= $23.25 × 4 fishes
= $93

At a store, apples cost each and oranges cost each. Harry buys some apples and oranges and spends . He buys a total of pieces of fruit.
Answer:
Number of apples = 6
Number of oranges = 5
Step-by-step explanation:
At a store, apples cost $0.80 each and oranges cost $0.95 each. Harry buys some apples and oranges and spends $9.55. He buys a total of 11 pieces of fruit.
Let
Number of apples = x
Number of oranges = y
x + y = 11 (1)
0.80x + 0.95y = 9.55 (2)
From (1)
x = 11 - y
Substitute into (2)
0.80x + 0.95y = 9.55 (2)
0.80(11 - y) + 0.95y = 9.55
8.8 - 0.80y + 0.95y = 9.55
- 0.80y + 0.95y = 9.55 - 8.8
0.15y = 0.75
y = 0.75/0.15
y = 5
Substitute y = 5 into (1)
x + y = 11 (1)
x + 5 = 11
x = 11 - 5
x = 6
Number of apples = 6
Number of oranges = 5

If OPQ is dilated from point Q by a scale factor of 3, which of the following equations is true about R'S'?
Answer:
segment R prime S prime = three segment RS
Step-by-step explanation:
I took the test,
The true statement is segment R prime S prime = three segment RS
What is dilation?Dilation is a transformation, which is used to resize the object.
The complete question is
If ΔOPQ is dilated from point Q by a scale factor of 3, which of the following equations is true about segment R prime S prime?
Triangle OPQ is shown with point R lying on side OP and point S lying on side OQ Line RS is perpendicular to side OQ.
segment R prime S prime = one half segment RS
segment R prime S prime = two segment RS
segment R prime S prime = segment RS
segment R prime S prime = three segment RS
The scale factor of dilation of ΔOPQ, S.F. = 3
S'Q' = 3 * SQ
also, R'Q' = 3* RQ
By Pythagoras theorem, we have
R'Q'² = R'S'² +S'Q'²
R'S'² = R'Q'² - S'Q'²
R'S'² = (3RQ)² - (3SQ)²
R'S'² = 9(RQ² - SQ²)
R'S' = 3 RS

Number of words he can read in 2 hours = 250 x 120 = 30,000
No: of words in each page = 400
No: of pages he reads = 30,000/ 400 = 75

Answer:

Step-by-step explanation:
The Celsius temperature, C, of a chemical reaction increases and then decreases over time according to the
formula C(t)=- +8t +93, where t represents the time in minutes. Use the Quadratic Formula to help
determine the amount of time, to the nearest tenth of a minute, it takes for the reaction to reach 110 degrees
Celsius.
Answer:
See explanations below
Step-by-step explanation:
Given the quadratic formula that expresses the temperature of a chemical reaction
C(t)=-12t² +8t +93
Given that C(t) = 110°, we are to find the value of t
Substitute
110 = -12t² +8t +93
-12t² +8t +93-110 = 0
-12t² +8t -17 = 0
12t² -8t + 17 = 0
Using the general formula;
t = -(-8)±√(-8)²-4(12)(17)/2(12)
t = 8±√64-816/24
t = 8±√-752/24
Since the value of t will give a complex number, hence the time doesn't exist when the reaction reaches 110°C
The temperature of the chemical does not reach 110°C
The equation is given as:
[tex]C(t)=-12t\² +8t +93[/tex]
When the reaction reaches 110 degrees, it means that:
C(t) = 110
So, we have:
[tex]110=-12t\² +8t +93[/tex]
Subtract 110 from both sides
[tex]0=-12t\² +8t +93 -110[/tex]
[tex]0=-12t\² +8t-17[/tex]
Rewrite the equation as:
[tex]12t\² -8t+17 = 0[/tex]
Using the quadratic formula, we have:
[tex]t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
So, we have:
[tex]t = \frac{-(-8) \pm \sqrt{(-8)\²-4(12)(17)}}{2(12)}[/tex]
[tex]t = \frac{-(-8) \pm \sqrt{-752}}{24}[/tex]
The square root of -752 is a complex number.
This means that, the equation does not have any solution when C(t) = 110
Hence, the temperature of the chemical does not reach 110°C
