Mathematics
1 answer:
Ray Of Light [21]3 years ago
8 0

Answer:

-9

Step-by-step explanation:

Replace x with -7 in the expression:

x^2 + 5 / x + 1

-7^2 + 5 / -7 + 1

49 + 5 / -6

54/-6

simplify the fraction

9/-1 = -9

Use the spinner below to find the probability of getting the following number after 1 spin. P(multiple of 3) = (Round to 4 decim
Talja [164]

The value of the probability P(multiple of 3) is 0.3333

<h3>How to determine the probability?</h3>

The spinner that completes the question is added as an attachment

From the attached spinner, we have:

  • Total section = 12
  • Multiples of 3 = 4

The probability is then calculated as:

P(multiple of 3) = Multiples of 3/Total

This gives

P(multiple of 3) = 4/12

Evaluate

P(multiple of 3) = 0.3333

Hence, the value of the probability is 0.3333

Drag each tile to the correct box.
Zielflug [23.3K]

The amount of heat depends on three factors:-

#Mass of the material used in bowls.

#Specific heat capacity of the material used in bowls.

#Temperature change.

So, (change in energy) = (mass) x (specific heat capacity) x (temperature change)

Temperature Change = (Change in energy) / (mass x specific heat capacity)

It says "The bowls start at the same temperature, and then the same amount of heat is added to each bowl". It means temperature change varies inversely with product of mass and specific heat capacity.

Higher the product of mass and specific heat capacity, Lower the temperature change, Cooler the bowl will be.

Water’s specific heat capacity is 4.186 joules/gram degree Celsius. Mercury’s specific heat capacity is 0.140 joules/gram degree Celsius.

Water and mercury are put into three identical bowls:

#Bowl A contains 20 grams of water.

#Bowl B contains 40 grams of water.

#Bowl C contains 20 grams of mercury.

So, we have (40g x 4.186 J/g) > (20g x 4.186 J/g) > (20g x 0.140 J/g)

It means temperature change in <u>Bowl B < Bowl A < Bowl C.</u>

<u>Hence, Order of the bowls from coolest to warmest, based on their final temperatures would be</u><u> Bowl B < Bowl A < Bowl C.</u>

A rectangular plot of land has an area 9/10 square mile.The length is 3/2miles whats the width
Georgia [21]
A = L * W
(9/10) = (3/2) * W
Divide both sides (3/2)
(9/10) / (3/2) = W
(9/10) * (2/3) = W
18/30 = W
6/10 = W
W = 3/5 mile
