If the temperature after 4.4 degree drop was -2.5 degrees Celsius what was the temperature at noon
Lostsunrise [7]

Answer:

1.9°C

Step-by-step explanation:

Let X be the temperature at noon and -2.5°C be the current temperature after the drop.

-We calculate temperature at noon as:

\bigtriangleup =t_o-t_n\\4.4=X--2.5\\\\X=4.4-2.5\\\\=1.5\textdegree C

Hence, the temperature at noon was 1.9°C

A cone has a mass of 6g and a radius of 5cm and a height of 2cm what is the density
goblinko [34]

Step 1

we know that

The density's formula is equal to

density=\frac{mass}{volume}

The volume of a cone is equal to

Volume=\frac{1}{3}\pi r^{2} h

where

r is the radius of the base of the cone

h is the height of the cone

in this problem

r=5cm\\ h=2 cm

substitute the values in the formula above

Volume=\frac{1}{3}*\pi*5^{2}*2

Volume=52.36\ cm^{3}

Step 2

Find the density

we have

Volume=52.36\ cm^{3}

mass=6\ g

substitute in the formula

density=\frac{mass}{volume}

density=\frac{6}{52.36}

density=0.11\frac{g}{cm^{3} }

therefore

<u>the answer is</u>

the density is 0.11\frac{g}{cm^{3} }

I need some help!
Katena32 [7]

Answer:

  11/60

Step-by-step explanation:

It is convenient to use the relationship between sine, cosine, and tangent.

tan(x) = sin(x)/cos(x) = (11/61)/(60/61)

tan(x) = 11/60

Beth read a total of 12 books over 7 months.
givi [52]

She has been with her book club for 49 months.

Step-by-step explanation:

Books read = 12 books

Time period = 7 months

Therefore,

12 books = 7 months

1 book = \frac{7}{12}\ months    

Books read so far = 84 books

Total time period = x

84 books = x months

1 book = \frac{x}{84}\ months

Using both unit rates;

\frac{x}{84}=\frac{7}{12}\\x=\frac{7}{12}*84\\x=\frac{588}{12}\\x=49\ months

She has been with her book club for 49 months.
