Answer:

This would probely be 266.

Step-by-step explanation:

There are three kids so I would divide them by three. Or multiply 266 by three. Of course there would still be 2$ left.

Answer:

Share of Eli, Freda and Geoff will be $180, $260, $360 respectively.

Step-by-step explanation:

Eli, Freda and Geoff were given $800 to share in the ratio of their age.

Their ages were 9 years, 13 years and 18 years respectively.

Ratio of their ages will be 9 : 13 : 18

Now share of Eli will be = \frac{9}{9+13+18}\times 800

= \frac{9\times 800}{40}

= $180

Share of Freda will be = \frac{13}{9+13+18}\times 800

                                     = $260

Share of Geoff will be = \frac{18}{9+13+18}\times 800

                                     = $360

Therefore, share of Eli, Freda and Geoff will be $180, $260, $360 respectively.

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

<h3>\frac{a + bc}{wd + f}  = g</h3>

<u>First of all cross multiply</u>

That's

g( wd + f ) = a + bc

<u>Multiply the terms at the left side of the equation</u>

We have

gwd + fg = a + bc

<u>Send fg to the right side of the equation</u>

That's

gwd = a + bc - fg

<u>Divide both sides by dg to make W stand alone</u>

<h3>\frac{gwd}{dg}  =  \frac{a + bc - fg}{dg}</h3>

We have the final answer as

<h2 /><h2>w =  \frac{a + bc - fg}{dg}</h2>

Hope this helps you

A quantity with an initial value of 6200 decays continuously at a rate of 5.5% per month. What is the value of the quantity afte
ELEN [110]

Answer:

410.32

Step-by-step explanation:

Given that the initial quantity, Q= 6200

Decay rate, r = 5.5% per month

So, the value of quantity after 1 month, q_1 = Q- r \times Q

q_1 = Q(1-r)\cdots(i)

The value of quantity after 2 months, q_2 = q_1- r \times q_1

q_2 = q_1(1-r)

From equation (i)

q_2=Q(1-r)(1-r)  \\\\q_2=Q(1-r)^2\cdots(ii)

The value of quantity after 3 months, q_3 = q_2- r \times q_2

q_3 = q_2(1-r)

From equation (ii)

q_3=Q(1-r)^2(1-r)

q_3=Q(1-r)^3

Similarly, the value of quantity after n months,

q_n= Q(1- r)^n

As 4 years = 48 months, so puttion n=48 to get the value of quantity after 4 years, we have,

q_{48}=Q(1-r)^{48}

Putting Q=6200 and r=5.5%=0.055, we have

q_{48}=6200(1-0.055)^{48} \\\\q_{48}=410.32

Hence, the value of quantity after 4 years is 410.32.

Write the slope-intercept form of the line between the two points.
DENIUS [597]
Answer: Y= -5x+2
First we need to find slope
M= y2-y1/x2-x1
M= -3-2/1-0
M= -5/1
M= -5
Now using slope intercept form we can solve this equation
Y-y1=m(x-x1)
Y-2=-5(x-0)
Y-2=-5x+0
Y= -5x+2
hope this helps!!

Which answer is in slope-intercept form for the given equation?
zhuklara [117]

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

Answer:

B. y = 4/9x + 4

slope = 4/9, y-intercept = 4

D. y = -4/9x - 4

slope = -4/9, y-intercept = -4
