kari74 [83]

The total cost for peaches is $0.40 you get that by (0.5)(0.80) as for oranges (0.7)(.90)=$0.63 so $0.40+$0.63=$1.03

Evaluate: -13 + (-21) - (-18) + 10 - (-23)

MArishka [77]

$Solution, -13+\left(-21\right)-\left(-18\right)+10-\left(-23\right)=17$

$Steps:$

$-13+\left(-21\right)-\left(-18\right)+10-\left(-23\right)$

$\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations},\\\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:$

$\mathrm{Apply\:rule\:}+\left(-a\right)\:=\:-a,\\+\left(-21\right)=-21,\\-13-21-\left(-18\right)+10-\left(-23\right)$

$-13-21=-34,\\-34-\left(-18\right)+10-\left(-23\right)$

$\mathrm{Apply\:rule\:}-\left(-a\right)\:=\:+a,\\-\left(-18\right)=+18,\\-34+18+10-\left(-23\right)$

$-34+18=-16,\\-16+10-\left(-23\right)$

$-16+10=-6,\\-6-\left(-23\right)$

$\mathrm{Apply\:rule\:}-\left(-a\right)\:=\:+a,\\-\left(-23\right)=+23,\\-6+23$

$-6+23=17$

$The\:Correct\:Answer\:Is\:17$

Tacoma's population in 2000 was about 200 thousand, and has been growing by about 8% each year. If this continues, what will Tac

Anestetic [448]

Answer:

Tacoma's population in 2014 will be 587,439 people

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by the formula

$y=a(1+r)^x$

where

y is Tacoma's population in thousand

x is the number of years since 2000

r is the rate of change

a is the initial value

we have

$a=200\\r=8\%=8/100=0.08$

substitute

$y=200(1+0.08)^x$

$y=200(1.08)^x$

what will Tacoma's population be in 2014?

Find the value of x

$x=2014-2000=14\ years$

substitute the value of x

$y=200(1.08)^{14}=587.439\ thousand$

therefore

Tacoma's population in 2014 will be 587,439 people

What is the m∠N ? Can someone help me :)

Sauron [17]

Answer:

<h2>61°</h2>

Step-by-step explanation:

Use the sine law:

$\dfrac{MO}{\sin(\angle N)}=\dfrac{NM}{\sin(\angle O)}$

We have:

$MO=18\\\\NM=6\\\\m\angle O=17^o\to\sin17^o\approx0.2924$

Substitute:

$\dfrac{18}{\sin(\angle N)}=\dfrac{6}{0.2924}$ <em>cross multiply</em>

$6\sin(\angle N)=(18)(0.2924)$

$6\sin(\angle N)=5.2632$ <em>divide both sides by 6</em>

$\sin(\angle N)=0.8772\to m\angle N\approx61^o$
