Hats are on sale for 45% off. Phyllis uses the expression p−0.45p to find the new price of a hat that originally cost p dollars.Use the drop-down menus to complete each sentence.
Answer:
The expression p−0.45p can be simplified to 0.55 p.
This means Phyllis can find the new price of a hat by finding 55 % of the original price.
Step-by-step explanation:
The given expression describes that the price of the Hat would be 55% of the original price.
Given that,
Hats are on sale for 45% off. Phyllis uses the expression p−0.45p to find the new price of a hat that originally cost p dollars.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Given expression,
= p−0.45p
Simplify further,
= 0.55p
The above expression implies that the outcome is 55% of p, where p is the original price of the Hats.
Thus, the given expression describes that the price of the Hat would be 55% of the original price.

Step-by-step explanation:
So for the first blue circle the line that goes to the middle that's the radius. And to solve the area you need to know the radius. The formula to solve the area is A = [tex]\pi[/tex] [tex]r^{2}[/tex] so what we would do its 3.14 times 6 times 6 or 3.14 times 36 which would give us the area! Now for circumference, the equation for that is C = 2[tex]\pi r^{2}[/tex] which would look like 2 times 3.14 times 6 times 6 or 2 times 3.14 times 36 and that would give you the circumference.

supose that the half-life of a cesium is 30 years. If there were initially 1000g of the substance,
a) give an exponential model for the situation
b) how much will remain after 200 years
After 200 years, 9.84 grams of Cesium would remain.
Let N represent the amount of substance after t years
The half-life of a cesium is 30 years., hence, this can be represented by exponential function:
[tex]N(t)=ab^t[/tex]
where a is the initial value and b is the multiplier.
There were initially 1000g of the substance
a) The exponential model for this situation is:
[tex]N(t) =1000(\frac{1}{2} )^{\frac{1}{30} t}\\\\N(t) =1000(\frac{1}{2} )^{\frac{t}{30}[/tex]
b) After 200 years (t = 200), the amount of Cesium remaining is:
[tex]N(200)=1000(\frac{1}{2} )^\frac{200}{30} \\\\N(200) = 9.84g[/tex]
Hence after 200 years, 9.84 grams of Cesium would remain

Answer:
see explanation
Step-by-step explanation:
f(x) = [tex]\frac{2x-5}{x-4}[/tex]
The denominator cannot equal zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be

There were 350 apples on the tree in March. By September there were 420 apples on the tree.
What was the percentage of change of apples on the tree? Round your answer to the nearest
tenth. *
Answer:
Step-by-step explanation:
20%
Answer:
The correct answer is 20.0% increase.
Step-by-step explanation:
In this situation, you would need to find how to find the percentage of change.
Therefore, you will need to first use subtraction, division and then multiplication to justify your answer.
--
First, find out how much the original number increased by.
[tex]420-350=70[/tex]
Next, divide the 70 with the original number, which is 350.
[tex]7[/tex] ÷ [tex]350=0.2[/tex]
Finally, to turn your decimal into a whole number, multiply by 100.
[tex]0.2[/tex] × [tex]100=20[/tex]

Answer:
ΔAOK ≅ ΔBOL by SAS
Step-by-step explanation:
Hello there!
We are given:
Line segment AB intersects line segment KL at point O
O is the midpoint of AB
O is the midpoint of L
We want to prove that ΔAOK is congruent to ΔBOL
From the given picture, line segments AK and LB don't exist, but we can draw them in
Once we've drawn them in, we can use the given information to help us
Since O is the midpoint of AB, AO = OB by the definition of a midpoint
O is also the midpoint of LK, and because of that, LO=OK, also because of the definition of a midpoint
Since O is the intersection of AB and KL, that means that O would help form the vertical angles <LOB and <KOA (which are congruent because of vertical angles theorem)
Now, we have 2 sides and an angle which are congruent.
In the answer, we already have ΔAOK filled in
Remember that when naming congruent triangles, the congruent pieces need to match
A corresponds with B
O corresponds with O
K corresponds with L
So, that means ΔAOK ≅ ΔBOL
The reason is because of SAS (side-angle-side). The reason why it's SAS is because we have 2 pairs of congruent sides and one angle which is congruent

Susan and Jim both babysit. Susan earns $15 for 2 hours and $30 for 4 hours. Jim’s charges are calculated using the equation t=7h+10 (t is the total and h is the hours) which statement is true
A.) Jim charges $7.00/hour, which is higher than Susan’s hourly rate
B.) Jim charges $10.00/hour, which is higher than Susan’s hourly rate
C.) Susan charges $7.00, which is equal to Jim’s hourly rate
D.) Susan charges $7.50, which is higher than Jim’s hourly rate
Please answer as soon a possible
Answer:
D.
Step-by-step explanation:
7h is the amount of money Jim makes per hour. You can find the amount of money Susan makes by dividing the amount she made to the hours:
15/2 = 7.50
Susan charges $7.50, which is higher than Jim's hourly rate. which is the correct answer would be a statement (D)
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
To find the hourly rate for Jim, you can plug in different values for h (the number of hours) in the equation t = 7h + 10 and solve for t (the total). For example, if h = 1, then t = 7(1) + 10 = 17. This means that if Jim babysits for 1 hour, he charges $17.
If you divide the total amount that Jim charges by the number of hours he works, you get his hourly rate. In this case, the hourly rate is t/h = 17/1 = $17/hour.
To find Susan's hourly rate, you can divide the total amount that she charges by the number of hours she works. For example, if Susan babysits for 2 hours, she charges $15, so her hourly rate is $15/2 = $7.50/hour. If Susan babysits for 4 hours, she charges $30, so her hourly rate is $30/4 = $7.50/hour.
Since Susan charges $7.50/hour, which is higher than Jim's hourly rate of $17/hour, the correct statement is D.) Susan charges $7.50, which is higher than Jim's hourly rate.
