The drawing shows a stack of alternating cups. The cups are 9.2 cm high. How many cups will fit in a door that is 211.77 cm high

KIM [24]

Answer:

The total number of whole cups that we can fit in the dispenser is 25

Step-by-step explanation:

It is given that the height of each cup is 20 cm.

But when we stack them one on top of the other, they only add a height of 0.8 to the stack.

The stack of cups has to be put in a dispenser of height 30 cm.

So we need o find out how many cups can fit in the dispenser.

Since the first cup is 20 cm high, the height cannot be reduced. So the space to fit in the remaining cups in the stack is only 30-20 cm as that’s the remaining space in the dispenser

So,

30 - 20 = 10 cm

To stack the other cups we have 10 cm of height remaining

As we know that addition of each adds 0.8 cm to the stack, the total number of cups that can be fit in the dispenser can be calculated by the following equation. Let the number of cups other than the first cup be denoted by ‘x’.

10 + 0.8x = 30

0.8x = 20

x = 25

The total number of cups that we can fit in dispenser is 25

Steve uses an app that shows him how many kilometers he has run to prepare for a marathon. The app said he ran 6.436 kilometers.

8_murik_8 [283]

Steve ran 4 miles.

Step-by-step explanation:

Given,

Distance = 6.436 kilometers

According to given statement;

1 mile = 1.609 kilometers

Therefore,

Distance in miles = $\frac{Distance\ in\ kilometers}{1.609}$

$Distance in miles =\frac{6.436}{1.609}\\Distance = 4\ Miles$

Steve ran 4 miles.

The width of a rectangle is one more than twice its length. If the rectangle's perimeter is 44 cm, then its length is ____ cm.

EleoNora [17]

Answer:

Part 1) The length is 7 cm

Part 2) The rate of return is r=11%

Step-by-step explanation:

Part 1)

Let

x ----> the length of rectangle

y ----> the width of rectangle

we know that

The perimeter of rectangle is equal to

$P=2(x+y)$

$P=44\ cm$

so

$44=2(x+y)$

simplify

$22=x+y$ -----> equation A

The width of a rectangle is one more than twice its length

so

$y=2x+1$ ----> equation B

substitute equation B in equation A

$22=x+(2x+1)$

solve for x

$3x+1=22\\3x=21\\x=7$

therefore

The length is 7 cm

Part 2) we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=1\ year\\ P=\$1,100\\ I=\$121\\r=?$

substitute in the formula above

$121=1,100(r*1)$

solve for r

$121=1,100(r)$

$r=121/1,100\\r=0.11$

Convert to percentage (Multiply by 100)

$r=0.11*100=11\%$
