Answer:

h=\frac{5\sqrt{3} }{3} \,\,m    

Step-by-step explanation:  

Let BC represents 5 feet across the floor, and AB represents the height.

Consider the figure in the attached file.

We know that,

\text{tan}\theta =\frac{\text{Perpendicular}}{\text{Base}}

\implies\text{tan}\,C\ =\frac{\text{AB}}{\text{BC}}

Here, \angle C=30^{\circ},\text{AB}=h\:\text{meters} , \text{and}\:\text{BC}=5\:\text{meters}

So, we have

\text{tan\,30}^{\circ}=\frac{h}{5}

\implies \frac{1}{\sqrt{3}}=\frac{h}{5}\:\:\left [ \because \text{tan\,30}^{\circ}=\frac{1}{\sqrt{3}} \right ]

\implies h=\frac{5}{\sqrt{3} }

\implies h=\frac{5\times \sqrt{3}}{\sqrt{3}\times \sqrt{3} }

\implies h=\frac{5\sqrt{3}}{3 } \,m

Hence, the mat is \frac{5\sqrt{3}}{3 } \,m high of the ground.

Margaret uses a credit card with a 21.7% APR compounded monthly to pay for her car repairs totaling $692.77. She can pay $290 pe
igomit [66]

Answer:

B. $715.21

Step-by-step explanation:

Apparently, Margaret makes her first payment after she has incurred a finance charge on the amount.

At the end of the first month, the balance due is ...

... 692.77×(1 + 0.217/12) = 705.30

At the end of the second month, the balance due is ...

... (705.30 -290)×(1 +0.217/12) = 422.81

At the end of the third month, the balance due is ...

... (422.81 -290)×(1 +0.217/12) = 132.81

Margaret makes total payments of $290×2 +132.81 = $712.81

Of the choices listed, the best selection is ...

... B. $715.21

_____

<em>Comment on the answer choice</em>

The total $715.21 seems to also include a finance charge on the final payment amount. (It actually includes a charge on $132.72, which is slightly different from the final payment amount.) There will not be any such charge, so the <em>available answer choices are all in error</em>.

Actually, we expect the total cost to be closer to $702.25, because we expect that Margaret will make her first payment before any finance charges are incurred.

_____

You should ask your teacher to show you in detail how to work this problem.

Victor plants 56 seeds in some flower pots if he puts 7 seeds in each pot how many flower pots does he have
Papessa [141]

Answer:

8

Step-by-step explanation:

The total seeds Victor plants in the flower pots=56

He puts 7 seeds in each pot.

So to find the number of pots;

You need to divide the total seeds(56) by the seeds put in each(7)

So it's going to be;

56÷7

=8

Therefore the total number of flower pots is 8.

I=prt,for p please show step by step for this variable
Bond [772]

Answer:

p = \dfrac{I}{rt}

Step-by-step explanation:

I = prt

Switch sides.

prt = I

We are solving for p. We want p alone on the left side. p is being multiplied by r and t, so we divide both sides by r and t.

\dfrac{prt}{rt} = \dfrac{I}{rt}

p = \dfrac{I}{rt}
