Two square ends of the rectangle: 2x4x4=32

Two triangular sides of the prism: 2x1/2x2x6=12

Back of prism: 2x4=8

Top of prism: 4x6.32=25.28

72+32+12+8+25.28=149.28

Beth is flying a kite with 300 feet of string. The kite gets stuck in a tree, so she ties the other end of the string to a rock
Paraphin [41]

Answer:

\displaystyle 172.1 ft

Step-by-step explanation:

<u>refer </u><u>the</u><u> attachment</u>

let the string be hypotenuse and

the height be h And the angle be 35°

given that,

  • hypotenuse:300ft
  • angle:35°

since we are given the hypotenuse and want to figure out the opposite side we'll use <u>sin</u><u> </u>function

so our equation would be

\displaystyle  \sin( {35}^{ \circ} )  =  \frac{h}{300}

cross multiplication:

\displaystyle h= 300 \sin( {35}^{ \circ} )

by using calculator we obtain:

\displaystyle h = 172.1

hence,

about <u>1</u><u>7</u><u>2</u><u>.</u><u>1</u><u>f</u><u>t</u><u> </u><u> </u>far up the tree is the kite

Recursive formula for 26, 24, 22, 20
dexar [7]

Answer:

a_n = 28-2n

Step-by-step explanation:

Given sequence is:

26,24,22,20

We can see that the difference between consecutive terms is same so the sequence is an arithmetic sequence

The standard formula for arithmetic sequence is:

a_n = a_1+(n-1)d

Here,

a_n is the nth term

a_1 is the first term

and d is the common difference

So,

d = 24-26

= -2

a_1 = 26

Putting the values of d and a_1

a_n = 26 + (n-1)(-2)\\a_n = 26-2n+2\\a_n = 28-2n

Hence, the recursive formula for given sequence is: a_n = 28-2n ..

Bruno says30% of 50 is smaller than 50% of 30Is Bruno right ? Explain your answer.
lora16 [44]

Answer:

He's wrong.

Step-by-step explanation:

30% of 50 is 3/10 * 50 = 15
50% of 30 is 1/2 * 30 = 15
As you can see, 30% of 50 is the same as 50% of 30.

56 coins = $9.80. how many are quarters how many are nickels​
nevsk [136]

Answer:

So there are 35 quarters and 21 nickels.

Step-by-step explanation:

So I guess that is all we have is quarters and nickels.

Quarters are worth .25

Nickels are worth .05

Let x represent the number of quarters

Let y represent the number of nickels

x+y=56

.25x+.05y=9.8

We are going to solve this system.

I'm going to use substitution. I will solve the first equation for y and then plug that into the second equation.

y=56-x  

.25x+.05(56-x)=9.8

.25x+2.8-.05x=9.8

.20x+2.8=9.8

.2x          = 7

 x=7/(.2) or 7*5=35

y=56-x

y=56-35=21

So there are 35 quarters and 21 nickels.
