The diameter of a circle is 14cm. Which TWO statements are correct?<br><br> A

Reika [66]

Answer:

(a) and (e)

Step-by-step explanation:

Given

$d = 14cm$

Required

Select the true statements

First, is a statement about the area.

The area is calculated as:

$Area= \pi*\frac{d^2}{4}$

So, we have:

$Area= 3.14*\frac{14^2}{4}$

$Area= 3.14*49$

(a) is true

Next, is a statement about the circumference.

This is calculated as:

$C = \pi d$

So, we have:

$C = 3.14 * 14$

(e) is true

a square painting has an area of 81x^2-90x-25. A second square painting has an area of 25x^2+30x+9. What is an expression that r

galina1969 [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

A1 ------> the area of the first square painting

A2 ----> the area of the second square painting

D -----> the difference of the areas

we have

$A1=81x^{2}-90x-25$

$A2=25x^{2}+30x+9$

case 1) The area of the second square painting is greater than the area of the first square painting

The difference of the area of the paintings is equal to subtract the area of the first square painting from the area of the second square painting

D=A2-A1

$D=(25x^{2}+30x+9)-(81x^{2}-90x-25)$

$D=(-56x^{2}+120x+34)$

case 2) The area of the first square painting is greater than the area of the second square painting

The difference of the area of the paintings is equal to subtract the area of the second square painting from the area of the first square painting

D=A1-A2

$D=(81x^{2}-90x-25)-(25x^{2}+30x+9)$

$D=(56x^{2}-120x-34)$

A library is open til' 5:00 P.M. On Wednesdays, the library closes 2 hours early. How many hours for a month is the library open

svet-max [94.6K]

So
if you assume that the month has 30 days and that the library opens at midnight, then
24 hours in a day
5 pm=12+5=17 hours
on wednessday=17-2=15 hours
wednessday=1/7 of week
so we find 1/7 of 30 which is 30/7=4 and 2/7
then subtract that from 30
30-4 and 2/7=25 and 5/7

ok so then we have
25 and 5/7 days is 17 hours and
4 and 2/7 days is 15 hours
so just multipy them and add

25 and 5/7 times 17=437.143 hours
4 and 2/7 days times 15 =64.2857
add

437.143+64.2856=501.429
so aprox 501.429

the real equation is $[(\frac{1}{7})(n)(15)]+[ (\frac{6}{7}) (n)(17)]=hours$ where n represents the number of days in the month

apros 501.429
