Answer:
145%
Step-by-step explanation:
When you want to find the percent of increase you need to divide the new price by the old price and move the decimal over two spaces to the right to make it a percent.
261/180=1.45=145%

A natural number is an integer greater than 0. Natural numbers begin at 1 and increment to infinity: 1, 2, 3, 4, 5, etc. Natural numbers are also called "counting numbers" because they are used for counting.
Answer:
The natural numbers (or counting numbers) are the fundamental mathematical set on which all other arithmetic is based. They do not include negative numbers. (The set of integers provides negative numbers.)

PLEASE MARK AS BRAINLEST Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-4, -2) B(-2, -2) C(-2, 7) and D(-4, 7).What is the area of rectangle ABCD?
A(-4,-2) B(-2,-2) C(-2, 7) D(-4, 7)
|AB| = √((-2-(-4))^2 + (-2 - (-2))
= √((2)^2 + 0^2) √4
= 2 units
|BC| = √((-2 - (-2))^2 + (7 - (-2))^2
= √5^2 = √25
= 5units.
Let |AB| = The length of the rectangle.
|BC| = The Width of the rectangle.
Hence Area = |AB| × |BC|
Area = 2 × 5 = 10 square units.
A certain county has a population of 34,237 people. The county hospital is interested in estimating the number of people in the county with blood-type A−. To do this, they test blood samples from 245 patients. Out of this group, 12 have blood-type A−. Use this sample to estimate the number of people in the county with blood-type A−.
Answer:
About 1677 people in the county will have blood-type A−.
Step-by-step explanation:
From the question, 12 out of 245 patients have blood-type A−.
To estimate the number of people in the county which has a population of 34,237 people with blood-type A−, we will assume that for every 245 people out of the 34,237 people, 12 of them have blood-type A−.
Let the number of people with blood-type A− in the county be x.
Now,
If 12 people out of 245 people have blood-type A−
Then, x people out of 34237 people will have blood-type A−
245 × x = 34237 × 12
245x = 410844
x = 410844/245
x = 1676.9
x ≅ 1677
Hence, about 1677 people in the county will have blood-type A−.

Sally grew 18 flowers with 9 seed packets. How many seed packets does Sally need to have a
total of 44 flowers in her garden? Assume the relationship is directly proportional.
Answer:
22 seed packets
Step-by-step explanation:
we can look at this in a couple of ways. the first way to solve this is an algebraic problem. we know that 18 flowers came from 9 packets so 18 is going to be on one side of the equation while 9 is going to be on the other. we dont know how many seeds were in each packet though so we will use x to represent the amount of seeds. now our equation looks like this: 18 = 9x. heres how to solve it:
given: 18 = 9x
to get x alone we divide each side by 9 because its the opposite of muliplication: 2 = x
answer: x = 2 seeds per packet
another way we could figure this out is by using proportions. when we see the ratio flowers to packet is 18:9, we can tell that it needs to be simplified. we know both 9 and 18 are divisible by 9 so when we do that we get the answer, our ratio of flowers to packets is 2:1.
next, we need to look back at how we solved that problem we just did, and plug in our new numbers. when doing it algebraically, we follow these steps:
plug in: 44 = (x)2
x times 2 is equal to 2x: 44 = 2x
to get x alone divide each side by 2 because its the opposite of multiplication: 22 = x
answer: x = 22
if we want to solve it using ratios and proportionalities, we set it up flowers to packets like before so we have the ratio 44:x. seeing that the ratio was 2:1 last time, we know that 44 is 2 times x, or x is 1/2 (half) of 44. so we can find half of 44 to get x. half of 44 is 22 so 44:22 is the ratio's answer.

Deez clothing is having a discount of 40% on all shirts let X represent the regular price of any show in the store enter an expression that can be used to find the sale price of any show in the store I know
Answer:
0.6X
Step-by-step explanation:
Given that :
Discount on shirt = 40%
Regular price of shirt = X
The sales price of shirt after applying the discount will become :
Regular price - discount on price
X - (40% of X)
X - (0.4x)
= 0.6x
Hence.the sales price of shirt will be : 0.6x
tammy will order both macaroni and potato salad. She estimates that she will spend a total of $38 on 7 pounds of salad. She uses this system of equations to show how many pounds of macaroni salad, m, and potato salad, p, she plans to buy. 5m + 6p = 38 m + p = 7 How many pounds of each salad does Tammy plan to buy?
Answer: Marcaroni salad = 4 pounds
Potatoes salad = 3 pounds
Step-by-step explanation:
From the question,
5m + 6p = 38 ......... i
m + p = 7 .......... ii
Multiply equation i by 1
Multiply equation ii by 5
5m + 6p = 38 ....... iii
5m + 5p = 35 ....... iv
Subtract equation iv from iii
p = 3
Since m+p = 7
Therefore, m + 3 = 7
m = 7-3
m = 4
Marcaroni salad = 4 pounds
Potatoes salad = 3 pounds

A 20 N model rocket launched vertically is clocked at 25 m/s when it is 15 m above the ground (and has expended a negligible amount of fuel). Use the work–energy principle to find the rocket’s initial speed.
27.4 m/s
40.2 m/s
17.8 m/s
30.3 m/s
30.3 m/s is the correct answer.
Lenny makes $55,000 and is getting a $2,500 raise per year. Karl makes $62000, with a $2,000 raise per year. Which inequality shows how many years, y, will it take for Lenny to earn more than or the same salary as Karl. 55000x + 2500 ≤ 62000x + 2000 55000 + 2500x < 62000 + 2000x 55000 + 2500x ≤ 62000 + 2000x 55000 + 2500x ≥ 62000 + 2000x
Answer:
[tex]55000 + 2500x \geq 62000 + 2000x[/tex]
Step-by-step explanation:
Given
Lenny:
Base Earnings = $55000
Raise = 2500 yearly
Karl:
Base Earnings = $62000
Raise = 2000 yearly
Required
Determine the inequality that takes years for Lenny to earn more or exact as Karl
Let y represent years:
Earnings = Base Earnings + Raise * Years
First, we need to determine Lenny's earning:
[tex]Lenny: 55000 + 2500 * x[/tex]
[tex]Lenny: 55000 + 2500x[/tex]
Next, we determine Karl's earning
[tex]Karl: 62000 + 2000 * x[/tex]
[tex]Karl: 62000 + 2000x[/tex]
To determine the required inequality, we have:
[tex]Lenny \geq Karl[/tex]
This gives:
[tex]55000 + 2500x \geq 62000 + 2000x[/tex]

Rewrite this single inequality as two inequalities with AND connector. -6 < x < 12 x > -6 and x < 12 x > 12 and x > -6 x < -6 and x > 12
Answer:
The single inequality -6 < x < 12, can be written as two inequalities thus
x > -6 and x < 12
Step-by-step explanation:
For the single inequality -6 < x < 12,
To write the single inequality as two inequalities, first we will separate it into two as
-6 < x and x < 12
-6 is less than x means x is greater than -6, Hence, -6 < x can be written as
x > -6.
∴-6 < x and x < 12 becomes
x > -6 and x < 12
Hence, the single inequality -6 < x < 12, can be written as two inequalities thus
x > -6 and x < 12
Therefore, the correct option is the first one
x > -6 and x < 12
