Answer:

Step-by-step explanation: Most urban designers incorporate a diagonal street cutting through the regular grid to create interesting spaces, squares, plazas, to provide relief and add character as can be seen at Manhattan Times Square created by Broadway cutting the grid at an angle.

4%

To find the percentage, first find the area of both circles. The area formula is $\pi r^{2}$ . After finding the area of the center of the target (19.625) and the area of the large target (490.625), set up a percent proportion to determine the percentage that the center takes up:

$\frac{is}{of} = \frac{percent}{100}$

$\frac{19.625}{490.625} = \frac{percent}{100}$

Cross multiplying and dividing by 490.625 will give a total of 4%.

You invested $ 7000 between two accounts paying 3 % and 5 % annual? interest, respectively. If the total interest earned for the

natita [175]

Answer:

In the first account was invested $\$3,000$ at 3%

In the second account was invested $\$4,000$ at 5%

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the 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

First account

$t=1 years\\ P=\$x\\ r=0.03$

substitute in the formula above

$I=x(0.03*1)$

$I=0.03x$

Second account

$t=1 years\\ P=\$(7,000-x)\\ r=0.05$

substitute in the formula above

$I=(7,000-x)(0.05*1)$

$I=350-0.05x$

Remember that

The interest is equal to $\$290$

Adds the interest of both accounts

$0.03x+350-0.05x=\$290$

$0.05x-0.03x=350-290$

$0.02x=60$

$x=\$3,000$

therefore

In the first account was invested $\$3,000$ at 3%

In the second account was invested $\$7,000-\$3,000=\$4,000$ at 5%

A circle has a diameter of 29 feet. What is the area? *

11111nata11111 [884]

Answer:

The answer is

<h2>660.5 square feet</h2>

Step-by-step explanation:

Area of a circle = πr²

where r is the radius

From the question

diameter = 29 feet

To find the radius given the diameter we use the formula

$radius = \frac{diameter}{2} \\ radius = \frac{29}{2} \\ = 14.5 \: \: feet$

So the area of the circle is

$A = {14.5}^{2} \pi \\ = 210.25\pi \\ = 660.519...$

We have the final answer as

<h3>660.5 square feet</h3>

Hope this helps you

Find the volume of the sphere. Round your answer to the nearest tenth.

shepuryov [24]

Answer:

179.50

Step-by-step explanation:

The formula for calculating pi is as followed: 4/3·π·r³

The question is either asking to calculate using 3.14 for π or add π at the end of your answer instead of completing it. I will substitute π for 3.14.

∴V=4/3·3.14·3.5³

V=179.503333333

Round your answer to the nearest hundredth:

179.503333333 rounded to the nearest hundredth becomes 179.50

∴V=179.50

-------------------------------------------------------------------------------------------------------------

Another way to answer this question is to use the same formula; but not substitute 3.14 into the answer.

V=π.4/3·r³

V=π·57.1666666667

Round 57.1666666667: 57.17

V=57.17π

Either one would work. Hope this works.

It's -25 in Alaska and 75 in Florida. How much hotter is it in Florida than in Alaska?

emmasim [6.3K]

Just subtract to find the difference.

75 - (-25) = 75 + 25 = 100.

It is 100 degrees hotter in florida than alaska.
