Step-by-step explanation:

Consider Similarity and enlargement

To get the enlargement factor,

Take the ratio result of any two similar sides. i.e

PQ/AB = 3.6/2 = 1.8

The enlargement factor is 1.8

To get ST, consider ED then multiply it by the enlargement factor. i.e

= 5 x 1.8

= 9

0.0323 as a fraction

svetoff [14.1K]

Answer:

» $\frac{323}{10000}$

Step-by-step explanation:

To convert the decimal 0.0323 to a fraction,

just follow these steps:

Step 1: Write down the number as a fraction of one:

$0.0323 = \frac{0.0323}{1}$

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 4 numbers after the decimal point,

So, we multiply both numerator and denominator by 10000.

Therefore ;

→ $\frac{0.0323}{1} = \frac{(0.0323 \times 10000)}{(1 \times 10000)} \\ \\→ \frac{323}{10000}$

After reading 80\%80% of her e-mails in her inbox, Danette still has MM unread e-mails.

NARA [144]

Answer: The correct options are.....

A) $\frac{M}{1-0.8}$ and

B) $5M$

Step-by-step explanation:

Suppose, the number of e-mails Danette had in her inbox before she started reading was $X$ .

Percentage of read emails is 80%, so the number of read emails $= (\frac{80}{100}*X)=0.8X$

Thus, the number of unread emails $= X-0.8X=X(1-0.8)$ , which is given as $M$ .

So, the equation will be........

$X(1-0.8)=M\\ \\ \Rightarrow X=\frac{M}{1-0.8} (Answer: 1) \\ \\ \Rightarrow X=\frac{M}{0.2}\\ \\ \Rightarrow X=(\frac{1}{0.2})M=5M (Answer: 2)$

Thus, the expressions which could represent the number of e-mails Danette had in her inbox before she started reading are: $\frac{M}{1-0.8}$ or $5M$

Surface area
break it down
bottom and top
bottom=5 rectangle
top=2 triangles+2rectangle
areas
area of recatngle=lw
area of traignle=1/2lw

so total is
SA=(8 times 2.8)+(2.8 times 4.8) +(2.8 times 4.8)+(4.8 times 8)+(4.8 times 8)+(5 times 2.8)+(5 times 2.8)+(1/2 times 3 times 8)+(1/2 times 3 times 8)
(I'm not going to do all the math, just the result)
SA=178.08 yd^2

split the figure into 2 parts
top and bottom
bottom=rectagular prism=lwh
top=triangle tingie, wait, if we take 1/2 of it and put it with the other, half, we get a rectangular prism with 1/2 base so

bottom=8 times 2.8 times 4.8=107.52
top=1/2 times 8 times 3 times 2.8=33.6
add them
107.52+33.6=141.12 yd^3

ANSWERS
SA=178.08 yd^2
V=141.12 yd^3
