C. Infinitely many
D.2

Answer:

35,000 feet

Step-by-step explanation:

So t is the atmospheric temperature

g is the ground temperature

First sub in the values that you know

t = -65.5 and g = 57

-65.5 = -0.0035a + 57

Rearrange: to make 'a' on its own

-65.5 - 57 = -0.0035a

-122.5/-0.0035 = a

Use a calculator

a = 35,000 ft

The hypotenuse should be 81.02 not 90

Answer:

the question is incomplete, so I looked for similar questions:

There are 3 sandwiches, 4 drinks, and 2 desserts to choose from.

the answer = 3 x 4 x 2 = 24 possible combinations

Explanation:

for every sandwich that we choose, we have 4 options of drinks and 2 options of desserts = 1 x 4 x 2 = 8 different options per type of sandwich

since there are 3 types of sandwiches, the total options for lunch specials = 8 x 3 = 24

If the numbers are different, all we need to do is multiply them. E.g. if instead of 3 sandwiches there were 5 and 3 desserts instead of 2, the total combinations = 5 x 4 x 3 = 60.

Step-by-step explanation:

Answer:

-5x+y=5

or,-5x=5-y

or,x=5-y+5

or,x=10+y......................as eqn (i)

Agn

or3x-6y=24..................as (ii)

putting the value of x in eqn ii

or 3(10+y)-6y=24

or 30+3y=24

or 30-24 =3y

or 6=3y

or y=6/3

or y=2

putting the value of y in eqn i

or x=10+y

or x=10+2

or x=12.

Answer:

y = -5; x = -2

Answer:

$130

Step-by-step explanation:

Given:

I = (S − P) / P

where,

P = purchase price and

S = sale price.

What was the purchase price of the stock?

I = 30%

S = $91

I = (S − P)/P

30% = (91 - P) / P

0.3 = (91 - P) / P

Cross product

0.3P = 91 - P

0.3P + P = 91

0.7P = 91

P = 91 / 0.7

P = $130

Answer:

Angle 1 and Angle 5

Step-by-step explanation:

Since we know that a straight angle is 180 degrees this means that angle 2+5+1 is 1/2 of a full angle. We also know that angle 2 is 90 degrees or a right angle, we can subtract 180 - 90 which equals 90 degrees. Since two complementary angles add up to 90 degrees. This 100% assures us that angle 1 + angle 5 are the two complementary angles.

Answer:

y = (2/3)x

Step-by-step explanation:

Note that (0, 0) and (3, 2) are both points on this line.  The change in y as we go from  (0, 0) to (3, 2) is +2 and the change in x is +3.  

The slope of this line is this m = rise/run = 2/3

and so the desired equation is y = (2/3)x

Answer:

-35, -33, -31

Step-by-step explanation:

Let the 3 consecutive odd integers be x+1,x+3,x+5

Given, x+1+x+3+x+5=-99

3x+9=-99

3x=-108

x=-36

The 3 odd integers are x+1 = -35, x+3=-33, x+5=-31

If this is not the answer you are looking for plz let me know

Let, after h hours both would charge the same amount.

Money charged by Alexa in h hours :

A = 40 + 10h    .... 1)

Money charged by Nick in h hours :

N = 0 + 50h      .... 2)

For equal charge :

A = N

40 + 10h = 50h

40h = 40

h = 1 hour

Therefore, Alexa and Nick would charge the same amount at first hour.

Hence, this is the required solution.

Answer:A

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the equation of the lines expressed as:

L1: y = 2/3 x - 3 and L2: y = -3/2 x +2

Comparing to the standard form of equation of a line y= mx+c

The slope of L1 is m1 = 2/3

The slope of line L2 is -3/2

Since their slope are not the same, therefore the lines are not parallel to each other.

For two lines to be perpendicular, the product of their slope is -1.

Let's check for both lines:

Check the product of their slope;

m1m2 =2/3 * -3/2

m1m2 = -6/6

m1m12 = -1

Since the product of their slope is -1, hence the lines are perpendicular to each other.
