Kai cuts out all the page numbers of a b\ook. He takes each number and cuts the numbers into separate digits (single digit numbe

Eduardwww [97]

Answer:

2,889 digits

Step-by-step explanation:

Total pages of the book = 999 pages

Page 1 - 9 cut separately = 9 digits

Page 10 - 99 = 90 pages

Total digits = 2(90)

= 180 digits cut separately

Page 100 - 999 = 900 pages

Total digits = 3(900)

= 2,700 digits cut separately

how many separate digits does Kai have when he is finished

Total separate digits Kai have when he is finished = 9 digits + 180 digits + 2700 digits

= 2,889 digits

Total separate digits Kai have when he is finished = 2,889 digits

MissTica

Answer:

Kira sent 19 text messages, Goran sent 14 text messages and Joe sent 57 text messages.

Step-by-step explanation:

Let be "k" the number of text messages that Kira sent during the weekend, "g" the number of text messages that Gora sent during the weekend and "j" the number of text messages that Joe sent during the weekend.

We know know that they sent a total of 90 text messages then:

$k+g+j=90$

Goran sent 5 fewer messages than Kira. This is:

$g=k-5$

And Joe sent 3 times as many messages as Kira. Then:

$j=3k$

The steps to solve this are:

- Substitute the second equation and the third equatio into the first equation and then solve for "k":

$k+(k-5)+(3k)=90\\\\5k-5=90\\\\5k=90+5\\\\k=\frac{95}{5}\\\\k=19$

- Substitute this value into the second equation to find "g":

$g=19-5=14$

- Substitute the value of "k" into the third equation to find "j":

$j=3(19)=57$

Solve the following multiplication and division problems.

algol13

Answer:

a. 22.5 km

b. 267.52 m

c. 95 m

d. $(4.2)(10^{-5})$ km

Step-by-step explanation:

a. You can convert from hectometers to kilometers, and then you can make the multiplication:

$\frac{5hm}{10}=0.5km$

$(3km)(0.5km)(15)=22.5km$

b. You can convert from centimeters to meters, and then you can make the multiplication:

$\frac{44cm}{100}=0.44m\\(19m)(0.44m)(32)=267.52m$

c. You only need to divide 1,140 meters by 12:

$\frac{1,140m}{12})=95m$

d. You can convert from hectometers to kilometers, from decameters to kilometers and from meters to kilometers, and divide this by 15:

$\frac{6hm}{10}=0.6km$

$\frac{7dam}{100}=0.07km$

$\frac{5m}{1000}=0.005km$

$\frac{(3km)(0.6km)(0.07km)(0.005km)}{15}=(4.2)(10^{-5})$ km

Answer:

$(x+y+z)^2$

Step-by-step explanation:

$x^2+2x(y+2)+(y+2)^2$

there is a factoring rule where

$a^2+2ab+b^2=(a+b)^2$

So,

a = x

b = y + z
