Claudia makes an initial deposit of $50 into her bank account. She deposits $20 into the account each week. Let x represent the

number of weeks Claudia makes a deposit, and let y represent the amount of money in her account. Which equation represents the amount of money in Claudia's account after x weeks?
y=20x−50

y=−20x+50

y = 50x + 20

y = 20x + 50

A book is in the shape of a right rectangular prism. It measures 812 inches tall, 7 inches wide, and 212 inches thick.
ki77a [65]
We know that
the Volume of a prism=a*b*c
a----> tall--------> 8 1/2 in=8.5 in
b-----> wide-----> 7 in
c-----> <span>thick-----> 2 1/2 in=2.5 in
therefore
V=8.5*7*2.5=148.75 in</span>³------------equal a 148 3/4 in³

the answer is the option <span>c 148 3/4 in³</span>

The tables below show running hours of three printers that produce greeting cards and the total number of greeting cards produce
AysviL [449]

<u>ANSWER</u>

The correct answer is A


<u>EXPLANATION</u>



To find the ink cost of each card coming from printer  B, we need to find the total cost from printer B and the total number of cards printed by Printer B.


The total hours of all the three printers over the three weeks

=40+45+55+50+50+30+45+40+60=415


The total hours of printer B only

=50+50+30=130


Total number of cards produced over the three weeks


=7950+7800+9600=25350


We can use ratio and proportion to determine the total cards produce by printer B only.


415:25350


130:x


If less, more divides


x=\frac{130\times 25350}{415} \approx7941


Total cost of Printer B in 130 hours

$=130 \times 15=1950


The ink cost

=\frac{1950}{7941}


=0.2456


$\approx 0.30

to 2 decimal places

Stackable polystyrene cups have a height h1=12.5 cm. Two stacked cups have a height of h2=14 cm. Three stacked cups have a heigh
RUDIKE [14]

Answer:

Approximately 59 stacked cups.

Step-by-step explanation:

Given,

Height of a cup = 12.5 cm,

Two stacked cups = 14 cm,

Three stacked cups = 15.5 cm,

........, so on,....

Thus, there is an AP that represents the given situation,

12.5, 14, 15.5,....

First term is, a = 12.5,

Common difference, d = 1.5 cm,

Thus, the height of x cups is,

h(x) = a+(x-1)d = 12.5 + (x-1)1.5 = 1.5x + 11

According to the question,

h(x) = 200

⇒ 1.5x + 11 = 200

⇒ 1.5x = 189

⇒ x = 59.3333333333 ≈ 59,

Hence, approximately 59 stacked cups will need.
