Answer:

The needed equation relating P to N is P = $2300 + 90 N

His total pay if he sells 21 copies of Math is Fun is 4,190.

Step-by-step explanation:

The base salary of Juan = $2300

The earning on per copy sold = $ 90

P : His Total Pay

N : Number of books copies he sells.

Noe, here his earnings per copy sold = $90

So, the total earnings after selling N copies = N ( earning after 1 copy)

= N ( $90) = 90 N

TOTAL EARNINGS = BASE SALARY + MONEY EARNED after selling N copies

or, P = $2300 + 90 N

So, the needed equation relating P to N is P = $2300 + 90 N

Now, in second case: N = 21

So, P = 2300 + 90 N = 2300 + 90 (21)

= 2300 + 1890= 4,190

or, P = 4,190

Hence, his total pay if he sells 21 copies of Math is Fun is 4,190.

Sandra throws an object straight up into the air with an initial velocity of 38 ft/s from a platform that is 30 ft above the gro

Makovka662 [10]

Answer:

The answer is C.

Step-by-step explanation:

Given formula h(t)=−16t2+v0t+h0 , where v0 is the initial velocity and h0 is the initial height.

In this case, the initial postion is a platform 30ft above ground so h0=+30

The initial velocity is 38 ft/s straight up into the air so v0=+38

h(t)=-16t2+38t+30

When the object hits the ground, h=0.

h=-16t2+38t+30=0

Simplifying 8t2-19t-15=0

(8t+5)(t-3)=0

t=-5/8 or 3

As time cannot be -ve, t=3s. The answer is C.

Area triangles? it says show work so pls do

coldgirl [10]

$\large{\underline{\underline{\pmb{\sf {\color {blue}{Solution:}}}}}}$

Given,

Area = 225 yd²

Base = 30 yd

Height = [To be calculated]

To find:

The height of the given triangle.

We know that, area of a triangle is:

$\frac{1}{2} \times (b \times h) \\ \\ \leadsto \frac{1}{2} \times (30 \times h) \\ \\ \leadsto \frac{1}{2} \times 30h \\ \\ \leadsto \frac{1}{ \cancel{2}} \times \cancel{30}h \\ \\ \leadsto1 \times 15h \\ \\ \leadsto \: h = 15 \: yd$

Therefore, the require height is 15 yd.

$\green\star$ Proof:

$\frac{1}{2} \times (b \times h) \\ \\ \leadsto \frac{1}{2} \times (30 \times 15) \\ \\ \leadsto \frac{1}{ \cancel{2}} \times \cancel{450} \\ \\ \leadsto1 \times 225 \\ \\ area = 225 {yd}^{2}$

PICTURE PLEASE HELP.

aksik [14]

By pythagorean theorem

a^2+b^2=c^2

We can find that PL is 12.65

and then by altitude theorem

MA*LA=PA^2

we can find the value of MA

12MA=16

MA=1.33

then by the pythagorean theorem

we can use to find PM

MA^2+PA^2=PM^2

so PM=4.22

then to find the are you multiply length by width

PM*PL

12.65*4.22

So the area is 53.38

Find the equation of the line that has a slope of 3 and passes through (-1, 2)

Nadusha1986 [10]

Answer:

y= 3x+5

Step-by-step explanation:

start with the linear equation formula

y= mx+b

indentify what you already have.

x= -1 and y= 2 and m(slope)= 3

We are solving for b, so plug in what you have.

2= 3(-1)+b

Simplify.

2= -3+b

Add 3 on both sides.

5= b

Rewrite your equation with the x and y values.

y= 3x+5
