Answer:

The final amount is $1109.81

Step-by-step explanation:

In order to find the total amount, start with the know amount, which is Ms. Moore's class. Her class raised $249. Now we can use that to find the amount from Ms. Aguilar's class.

$249 + $396.62 = $645.62

Now we can use the amount from Ms. Aguilar's class to find the amount from Ms. Barry's class

$645.62 - $430.43 = $215.19

Now we can add the three amounts together to find the total amount.

$249 + $645.62 + $215.19 = $1109.81

Suppose that a new company that makes yo yos made 560 yoyos the first week the company overestimated its requirements. The manag
KATRIN_1 [288]

Answer:

312 yoyos in 8th week; 3407 yoyos over 8 weeks

Step-by-step explanation:

The <em>formula for the nth term</em> of a geometric sequence is

aₙ = a₁rⁿ⁻¹

In your geometric sequence, a₁ = 560 and r = 0.92.

Thus, the formula for your sequence is

aₙ = 560(0.92)ⁿ⁻¹

Eighth term

a₈ = 560(0.92)⁷ = 560 × 0.5578 = 312

The company will manufacture 312 yoyos in the eighth week.

Sum over eight weeks

The formula for <em>the sum of the first n terms</em> of a geometric series is

Sum = a₁[(1 - rⁿ)(1 - r)]

Sum = 560[(1 - 0.92⁸)/(1 - 092)]

       = 560[(1 - 0.513 22)/0.08 ]

       = 560 × (0.486 78/0.08)

       =  560 × 6.0848

       = 3407

The company will manufacture a total of 3407 yoyos over eight weeks.

Find y. Question attatched.
ICE Princess25 [194]

Answer: y=4

Step-by-step explanation:

We have a khown angle wich is 30 degree .

Cos 30 = root square of 3 /2

So root sqaure of 3/2 = 4 root square 3 / x

X= 4 r.sq 3 / r.sq 3/2 = 8

So we just need to apply the pythagorian theorem

X^2= y^2+ 48

64 = y^2 +48

Y^2 = 16

Y=4

Find the area of this shape.
mart [117]

Answer:

shape AREA= 35cm^2

Step-by-step explanation:

you should know that this shape is a combination of triangle and trapezoid. therefore you have to find the area of each shape and add them.

A=h/2(b1 + b2) for trapezoid

A=2/2((4+4)+4)

A=1*12

A=12cm^2

A=bh/2. for TRIANGLE

A=1/2((4+4)*5.75)

A=1/2(46)

A=23cm^2

shape AREA= triangle AREA + trapezoid AREA

shape AREA=12cm^2 + 23cm^2

shape AREA= 35cm^2
