That's a diagonal, so the hypotenuse of a right triangle,

d² = 80² +270² = 79300

Evaluate each expression a3 for a=5
nadezda [96]
I'm assuming you meant to say a^3. If so, then

a^3 = a*a*a
a^3 = 5*5*5
a^3 = 125

A regular hexagon rotates counterclockwise about its center. It turns through angles greater than 0° and less than or equal to 3
Bogdan [553]
Hey there Caleb!

To start of, the sentence was clear on that it said . . . 

\boxed{A \ regular \ hexagon \ rotates \ counterclockwise \ about \ its 
 \ center }

The statement listed above is the (key) point. We need to keep this in mind.

So, now that we know this.

We would use the mathematic (Ф)

So,sense we know that a (hexagon) had it's (6) shapes, we would do . . . 

Ф = 360° : 6 = 60°

Your correct answer to this question would be . . . 

\boxed{\boxed{60}}

Hope this helps.

Phyllis invested 50000 dollars, a portion earning a simple interest rate of 5 percent per year and the rest earning a rate of 7
Elodia [21]

Answer:

The amount invested at 5% was $39,000 and the amount invested at 7% was $11,000

Step-by-step explanation:

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

Let

x-----> the amount invested at 5%

50,000-x -----> the amount invested at 7%

so

t=1\ year\\ I=\$2,720\\r_1=0.05\\r_2=0.07\\P_1=\$x\\P_2=\$(50,000-x)

substitute in the formula above

2,720=x(0.05*1)+(50,000-x)(0.07*1)

solve for x

2,720=0.05x+3,500-0.07x

0.07x-0.05x=3,500-2,720\\0.02x=780\\x=\$39,000

(50,000-x)=\$11,000

therefore

The amount invested at 5% was $39,000 and the amount invested at 7% was $11,000
