Answer:

It will take them 15 minutes.

Step-by-step explanation:

1. Since you are given the information that the two typists are typing a certain amount of words in the same time frame (ie. one minute), you can add the two values together to obtain the total number of words the typists would type together in one minute:

95 + 98 = 193 words

2. To calculate how many minutes it would take them to type 2,895 words, you would simply take this total number of words and divide it by the number of words they collectively type in one minute (found in 1.). Thus:

2895/193 = 15

Therefor, it will take them 15 minutes to type 2,895 words.

Been a while since I’ve needed to not use a calculator. Why is -2X10^-18 (3/16) = 4.09X10^-19?
Anestetic [448]

Answer:

see the explanation

Step-by-step explanation:

we have

2.18*10^{-18}(\frac{3}{16})

we have that

\frac{3}{16}=0.1875

Convert to scientific notation

0.1875=1.875*10^{-1}

substitute

2.18*10^{-18}(1.875*10^{-1}})

Remember that

To multiply two numbers in scientific notation, multiply their coefficients and add their exponents

2.18*10^{-18}1.875*10^{-1}}=(2.18*1.875)*10^{(-18-1)}=4.0875*10^{-19}

Round the number 4.0875 two decimal places

so

4.0875*10^{-19}=4.09*10^{-19}

What is the solution for this inequality?<br> 5x&lt; 45<br> O A.<br> OB.<br> Oc.<br> XS-9
Elodia [21]

Answer:

x < 9

Step-by-step explanation:

Hello!

We solve inequalities the same we would solve equations. What we do to one side we have to do to the other.

5x < 45

Divide both sides by 5

x < 9

The answer is x < 9

Hope this helps!

Could someone please check my answer and explain? im not sure if im doing this right
Juli2301 [7.4K]

Answer:

V=1071.78\ cm^3

Step-by-step explanation:

Given that,

The radius of the cone, r = 8 cm

The height of the cone, h = 16 cm

We need to find the volume of the cone. The formula for the volume of the cone is given by :

V=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times 3.14\times 8^2\times 16\\\\V=1071.78\ cm^3

So, the volume of the cone is equal to 1071.78\ cm^3.
