Answer:

150 m

Step-by-step explanation:

Total distance walked

= perimeter of the garden

= 42 + 42 + length of arc

= 84 +  \frac{  \theta}{360 \degree}  \times 2\pi \: r \\  \\  = 84 +  \frac{90 \degree}{360 \degree}  \times 2 \times  \frac{22}{7}   \times 42 \\  \\ =  84 +  \frac{1}{4}  \times 44  \times 6 \\  \\  = 84 + 11 \times 6 \\  \\  = 84 + 66 \\  \\  = 150 \: m

If = 80°, and m∠BED = 25°, what is ?<br><br> 55°<br> 30°<br> 65°<br> 20°
Tomtit [17]
The complete question in the attached figure

we know that
<span>The measure of the external angle is the semidifference of the arcs that it covers.
so
</span><span>m∠BED =(1/2)*[mAC-mBD]-------> solve for mBD
mBD=mAC-2</span>m∠BED
mBD=80-2*25--------> mBD=30°

the answer is
mBD=30°

A person invests 10000 dollars in a bank. The bank pays 4.5% interest compounded
Greeley [361]

The person would have to leave the money in the bank for 7.8 years for it to reach 13,500 dollars.

Step-by-step explanation:

Step 1; First we must calculate how much interest is generated for a single year. The annual interest rate is 4.5% i.e. 4.5% of 10,000 dollars which equals 0.045 × 10,000 = 450 dollars a year. As the years pass, more and more will be put into the account due to interest.

Step 2; For there to be 13,500 dollars in the bank account we need to calculate how much money is added due to interest.

The money needed to be added through interest = 13,500 - 10,000 = 3,500 dollars.

So we need to determine how long it will take for the bank to add 3,500 dollars by adding 450 dollars a year.

The number of years to reach 13,500 dollars = \frac{3,500}{450} = 7.777 years. By rounding this value to the nearest tenth, we get 7.8 years.

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of in
erastova [34]

Answer: x= 187.5p

Step-by-step explanation:

Given : An equation relating packets to bytes of information : b = 1,500p where<em> p</em> represents the number of packets and <em>b</em> represents the number of bytes of information.

1 byte = 8 bits

Let x= Number of bits such that 1 b = 8x

Put b = 8x in given equation , we get

8x=1500p

Divide both sides by 8 , we get

x= 187.5p

Hence, the equation represent the relationship between the number of packets and the number of bits : x= 187.5p

What's the difference between using f(2) and f(x)=2?
BabaBlast [244]
F(2) means that you are plugging in 2 for x, while f(x)=2 means that the equation equals 2 (y=2) at a certain x value.
