2 answers:

Step-by-step explanation:

First, we need to find the unit rate of each animal (how many feet each animal can fly in a second). We do this by dividing the number of feet flown by the number of time.

Bat: 232/4 = 58 ft per second
Hummingbird: 343/7 = 49 ft per second

Based off of this information, we can conclude that the bat can fly faster than the hummingbird.

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

2x^2 - 7x - 6 = 0

$x1 = \frac{- b + \sqrt{ {b}^{2} - 4ac }}{2a}$
$x2 = \frac{- b - \sqrt{ {b}^{2} - 4ac }}{2a}$
where a=2
where b=-7
where c=-6

solve for x1 and x2

x1=4.21
x2=-0.71

A sandwich store charges a delivery fee to bring lunch to an office building. One office pays $33 for 4 turkey sandwiches. Anoth

shutvik [7]

Answer:

$12

Step-by-step explanation:

assuming that the cost of delivery is constant irrespective of the number ordered

Let the cost of sandwich be x

First office

$33=4x+c where c is the cost of delivery

Second office

$61=8x+c

These two are simultaneous equation. Subtracting the equation of first office from the second office we obtain

4x=28

Therefore, x=28/4=7

The cost of delivery is 33-(4*7)=33-28=5

Therefore, one sandwich plus delivery costs 7+5=$12
