Answer:

Weakest value = 0.0196

Strongest value = 0.5929

Step-by-step explanation:

Given:

Choices

0.691

-0.14

-0.24

-0.77

Computation:

0.691² = 0.477481

-0.14² = 0.0196

-0.24² = 0.0576

-0.77² = 0.5929

Weakest value = 0.0196

Strongest value = 0.5929

Sally is having a party and she has invited nine of her friends.

Alexeev081 [22]

Answer:

1) 5 limes, 5 lemons, 1,000 mL of pineapple juice, 2,000 mL of lemonade, 1,000 of orange juice

2) Limes = $2, Lemons = $2.5, Lemonade = $1.60, Orange Juice = 80c, Pineapple Juice = 90c

Step-by-step explanation:

1/2 limes · 10 = 5

1/2 lemons · 10 = 5

100 mL of pineapple juice · 10 = 1,000 mL

200 mL of lemonade · 10 = 2,000 mL

100 mL of orange juice · 10 = 1,000 mL

Cost:

5 limes · 0.4 = $2

5 lemons · 0.5 = $2.5

mL to L

1,000 mL of pineapple juice = 1 L, this costs 90¢

2,000 mL of lemonade = 2 L, this costs $1.60

1,000 mL of orange juice = 1 L, this costs 80¢

Overall:

5 limes for $2

5 lemons for $2.5

1 L of of pineapple juice for 90¢

2 L of lemonade for $1.60

1 L of orange juice for 80¢

Jake is choosing between 2 cell phone plans. Plan A costs $15 per month plus $0.08 per minute. Plan B costs $35 per month for un

Alex73 [517]

Answer:

The system of equations is

$y=0.08x+16$

$y=35$

Step-by-step explanation:

Let

x ----> the number of minutes of calling time

y ----> the monthly cost of the calling plan

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

In this problem

Plan A

$m=0.08\\b=16$

substitute

$y=0.08x+16$ ----> equation A

Plan B

$m=0\\b=35$

substitute

$y=35$ ----> equation B

therefore

The system of equations is

$y=0.08x+16$

$y=35$
