(b) The pizzeria sold 85 pizzas yesterday. Suppose the number of pizzas sold today was 60. Determine the percent increase or decrease in the pizzas sold, rounded to the nearest hundredth. Show your work.
_____________ % (Increase or decrease?)
PLEASE SHOW WORK thank you :D
Answer:
The difference is 21.21%
work shown below
Step-by-step explanation:
I'm going to first find the difference between both.
85-60=25
Now, we have to find 25% of 85
We don't have to use the formula, we can do this in our brain, like this -
We can see that 25% of 80 = 20, since 25 = 1/4, and 1/4 of 80 = 20, then, there is the 5 part left, how do we find that??? well, 25% of 5 = 1.25, since 1.25x5=5,
So hence, our answer is 21.25

In this case, the old number is 85, and the new number (today's pizza number) is 60.
(85 - 60) / 85 x 100 =
(85 - 60 = 25)
25 / 85 = 0.29411764705
0.29411764705 x 100 = 29.411764705
Now, round it to the nearest hundredth.
29.4118 (decrease)

It takes 5 minutes for an individual to shower. Of each person showers twice per day, approximately how long does each person spend showering in a year?
Answer:
c
Step-by-step explanation:
Beejjj
Each person spends 2.53 days showering in a year.
What is algebra?Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.
Given that,
Time taken by one person to shower = 5 minutes.
Also, one person take shower 2 times in a day.
Total time taken to shower twice per day = 5 x 2 = 10 minutes.
Since, in one year total number of days = 365.
Time taken to shower in 365 days = 365 x 10 = 3650 minutes.
In one day total number of minutes = 24 x 60 = 1440 minutes.
Total days = 3650 / 1440 = 2.534722 days = 2.53
Person showers for 2.53 days in a year.

Write the equation of the transformed graph of tangent with period 4 that has
been shifted vertically up 3 units. (3 points)
Answer:
g(x) = 3 + tan(πx/4)
Step-by-step explanation:
A tangent function has a period of π. In order to make it have a period of 4, it needs to be stretched horizontally by a factor of 4/π. A function is stretched horizontally by a factor of k by replacing x with x/k.
In order for the function to be shifted vertically up by 3 units, 3 must be added to the function value. That is, the transformed function becomes ...
g(x) = tan(x/(4/π)) +3
g(x) = tan(πx/4) +3
Solve for all missing sides and angles.
Answer:
Step-by-step explanation:
Sum of interior angles in a triangle is 180degree.
<B + 15degree + 45degree = 180degree
<B = 180 - 45 - 15 = 120 degree
By sine rule,
sin<B / AC = sin<C / AB = sin <A / BC
sin120degree / 200 = sin15degree / AB = sin45degree / BC
AB = 200*sin15degree/sin120degree
= 59.77
BC = 200*sin45degree/sin120degree
= 163.30

Examine the two boxes.
Box A
Box B
How much greater is the surface area of Box A than Box B?
Answer:
Box A is greater than Box B by 34.
Step-by-step explanation:
First, you need to start with finding the surface area of every individual side on Box A we have side A, B, and C. After finding the individual area for each side, double each area because there is two of each side. This is the the same method you apply to Box B.
Then subtract the surface area of Box B from Box A.
Paul, Shawn and Tim have a box of marbles. Paul has 1/5 of the marbles. Shawn has 3/8 of the remainder and Tim has has the rest of the marbles. Tim has 84 marbles more than Paul. How many marbles are in the box?
Answer:
374 marbles
Step-by-step explanation:
Paul (P) has 1/5 this was given
Shawn (S) has 3/8 this was given
That means Tim (T) must have 17/40 because 1/5 + 3/8 = 23/40 and 1- 23/40 = 17/40
Those are the fractional amounts each boy has. We can set up an equation based on the information in the problem to get the total number of marbles (M). Tim has 84 marbles more than Paul. Thus, Tim has a greater number of marbles. 84 more, to be exact. Our equation would then look like this:
P+84=T
Because we have three unknowns, we need three equations. Thus, we need two more, but we can get them from our fractions at the top.
We need to have a question where we find the total number of marbles.
We know that Paul has 1/5 of the marbles. We can use M to represent the total number of marbles.
P = (1/5)M
T= (17/40)M
We had this from before: P+84=T
If we substitute into the equation:
(1/5)M + 84 = (17/40)M
Now there is only one variable in the equation and we can solve for M.
For M, I got 1120/3 which simplifies to 373 and 1/3, since there cannot be 1/3 of a marble, we can round to 374. There are three hundred, seventy-four marbles in the box.
If you want to check the answer, you can put (1120/3) back in for M in the third equation and you will see that each side is equivalent.

You play basketball at your school’s indoor stadium. You have two payment options. Option A is to buy a membership card for $20 and pay $2 each time you go to the gym, t. Option B is to pay $4 each time you go. After how many trips to the gym will the costs be the same?
The costs are the same after
trips to the gym.
Answer:
10 times
Step-by-step explanation:
Let x be the amount of times you go to the gym
Option A would be 20+2x
Option B would be 4x
now the question is after how many trips would the cost be the same?
20+2x=4x
Solve the equation so
20=4x-2x
20=2x
X=10
It would take 10 times for the cost to be the same for both options

Answer:
254 units^2
I took the test and got it correct.
The surface area of a cone that has a radius of 5 units and a
height of 10 units is 508.06 square units.
What is surface area?Surface area is the total area of the exposed surfaces of a three-dimensional object. It is the sum of all the areas of the exposed faces of the object, including any curved surfaces. The formula to find the surface area of a cone is A=πr(r+√(h²+r²)).
Given that, radius of a cone is 5 units and the height of a cone is 10 units.
Surface area = 3.14×10(5+√(10²+5²)
= 508.06 square units
Therefore, the surface area of a cone that has a radius of 5 units and a
height of 10 units is 508.06 square units.
