Write the inequality (without solving)

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

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:

Step-by-step explanation:

Equation:

Total cost = $4 + $2(admission)

y = 4 + 2x

Initial value:

when x= 1 (one admission)

y= 4 +2(1) =6

so, $6

Rate of change:

m= $2

Answer:Slope Intercept

Y=2/3m-6

Answer:

n= - 1

Step-by-step explanation:

3n - 5 = -8(6+5n)

3n-5 = -48 - 40n

3n+40n = -48 + 5

43n = -43

n=-1

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

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]

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

Answer: Since PR is the long line, PT is half of PR so 34/2 = 17

Answer:

Step-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

Answer:

C: (-2,-2)

Step-by-step explanation:

if you move it down to the left 90 degrees it will move to where the D spot is and the coordinates are (-2,-2)

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

Given :

Manual is a word processor operator and makes $11.50 an hour.

To Find :

How much is his gross earnings for one week if he worked a total of 52 hours.

Solution :

The operator makes $11.50 in an hour.

So, amount he make if he work 52 hours in a week is :

A = $(52 × 11.50)

A = $598

Therefore, the weekly income for this week is $598.

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.

Answer:

Step-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
