Answer:
4
Step-by-step explanation:
2+2 = 4
Answer:
2
Step-by-step explanation:
x²+2xy+y²
Here x² has degree 2
2xy has degree also 2 because x has 1 degree and y has 1 degree so 1+1=2
y² has degree 2
So the highest degree of the expression is 2

Answer:
63 miles / hour = 0.0175 miles / secondStep-by-step explanation:
63 miles per hour also equals 0.0108225108225108 feet per second.
Which does not really help you if you don't know how to convert feet per second to miles per second.
How to convert miles per hour to miles per second is fairly easy, with a calculator.
1 mile per hour equals 0.000277777778 miles / second,
and if you multiply 0.000277777778 by 63, you get = 0.01750000001
Which can be rounded to get 0.0175

A company that makes hair care products at 7000 people trying to shampoo of the 7000 people 28 had a mild allergic reaction what percent of the people had a mild allergic reaction
Answer:
0.4%
Step-by-step explanation:
Given that:
Number of people with mild allergic reaction = 28
Total number of people = 7000
To find:
Percentage of people who have a mild allergic reaction to the shampoo = ?
Solution:
First of all, let us understand how can we calculate percentage of a particular amount.
Percentage of a particular amount can be calculated by dividing the amount with the total amount and then multiplying it with 100.
Percentage of [tex]p[/tex] from [tex]q = \frac{p}q\times 100[/tex]
Here,
[tex]p = 28\\q =7000[/tex]
Therefore, the percentage of people who have mild allergic reaction:
[tex]\dfrac{28}{7000}\times 100\\\Rightarrow \dfrac{2800}{7000} \\\Rightarrow 0.4\%[/tex]

If you randomly choose two letters from the word "JANUARY ", find the probability that you choose letter J first and then A after replacing the first. Round answer to nearest tenth and include percent sign. Also, does this represent an independent or dependent scenario?
Answer:
2.0%
Step-by-step explanation:
The probability of two events happening in the sequence is calculated by multiplying the probability of each event happening separately by one another. Since there are a total of 7 letters in this word then the probability of choosing one letter correctly is [tex]\frac{1}{7}[/tex] . Since the first letter is replaced before choosing the second letter the probability remains the same. Therefore, the sequence would be the following...
[tex]\frac{1}{7} * \frac{1}{7}[/tex] = 0.020164 or 2.0%
This is an independent scenario because it does not depend on any external factors and under these circumstances the percentage will remain the same.
Joseph's lunch at a restaurant costs $13.00 without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax. What is the total cost of the lunch, including the tip
Answer:
The total cost of the lunch including the tip is $15.21.
Step-by-step explanation:
To find the total cost of the lunch including the tip, first, you need to calculate 17% of the price of the lunch as the statement indicates that that is the tip Joseph leaves the waiter:
$13*17%=$2.21
Now, you need to add that amount to the price of the lunch:
$13+$2.21=$15.21
According to this, the answer is that the total cost of the lunch including the tip is $15.21.

Answer:
$10.12Step-by-step explanation:
Step one:
given data
we are told that the cost of binoculars is $155.75
and also the sales tax is 6.5%
Step two:
We want to first solve for the sales tax which is 6.5% of $155.75
=6.5/100* 155.75
=0.065*155.75
=10.12
Nick will pay a tax of $10.12
Also Nick will pay a total amount of
= 155.75+10.12
=$165.87

solve 2v^2+4v=6 by factoring.
Answer:
v = 1 or -3
Step-by-step explanation:
2v^2 + 4v = 6
take 2 as common
2(v^2 + 2v = 3)
v^2 + 2v = 3
Now,
v^2 + 2v - 3 = 0
v^2 - v + 3v - 3 = 0
v(v - 1) + 3(v - 1) = 0
(v - 1) (v + 3) = 0
v = 1 or -3
Answer:
<=>v²+2v-3=0
<=>v²-v+3v-3=0
<=>v(v-1)+3(v-1)=0
<=>(v-1)(v+3)=0
<=>*v-1=0
v=1
*v+3=0
v=-3
A scientist uses a submarine to study ocean life.
• She begins at sea level, which is at an elevation of o feet
• She travels straight down for 90 seconds at a speed of
3.5 feet per second
• She then travels directly up for 30 seconds at a speed of
2.2 feet per second
After this 120 second period, how much time, in seconds, will it take for the scientist to
travel back to sea level at the submarine's maximum speed of 48 feet per second?
Round your answer to the nearest tenth of a second.
Show your work
Answer:
5.2 seconds
Step-by-step explanation:
Traveling straight down: 90 * 3.5 = 315 feet down
Traveling up: 30 * 2.2= 66
315-66= 249
249/48= 5.1875 seconds
5.2 seconds <- rounded

A restaurant has 9 3/5 pounds of onions. The restaurant's manager ordered 4 4/5 more pounds of onions. The onions then were mixed and kept in 2 baskets with each basket having equal pounds on onions. How many pounds of onions does each basket contain?
Answer:
7 1/5 pounds in each basket
Step-by-step explanation:
Original pounds of onion = 9 3/5
New pounds of onion = 4 4/5
The onions then were mixed and kept in 2 baskets with each basket having equal pounds on onions
Total onions = Original pounds of onion + New pounds of onion
= 9 3/5 + 4 4/5
= 48/5 + 24/5
= 48+24/5
= 72 / 5 pounds
How many pounds of onions does each basket contain?
Pounds in each basket = Total pounds /2 basket
= 72/5 ÷ 2
= 72/5 × 1/2
= 72 / 10
= 7 2/10
= 7 1/5 pounds in each basket

Mike bought five items for lunch that cost a total of $4.55. Hot dogs cost $1.10 each and cookies cost $0.75 each. Which of these systems of equations below could be used to determine h , the number of hot dogs, and c , the number of cookies, Mike bought for lunch?
Answer:
1.1h+0.75c=4.55---------------1
h+c=5--------------2
Step-by-step explanation:
Step one:
given data
total lunch items= 5
let hot dogs be h
and cookies be c
cost of hot dogs = $1.10
cost of cookies = $0.75
total cost = $4.55
Step two:
The linear model for the total cost is given as
4.55=1.1h+0.75c---------------1
and the model for the number of items is
h+c=5--------------2
The systems of the equation for the situation is
1.1h+0.75c=4.55---------------1
h+c=5--------------2
