Analyze the diagram below and complete the instructions that follow. / Find the value of x. A. 4 B. 5 C. 6 D. 9
WARRIOR [948]

Answer:

C

Step-by-step explanation:

x^2 + (x+3)^2 = 117

x^2 + x^2+6x+9 =117

2x^2 + 6x - 108 = 0

(2x-12)(x+9)=0

x=-9,6

x cannot be negative therefore, x = 6

Hank has 50 peso, 200 peso and 500 peso bills in his wallet. He has five less 200 bills as 50 bills, and half as many 500 bills
Varvara68 [4.7K]

For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso.

<h3>How to apply systems of linear equations in real life equations</h3>

In this question we must translate the statement of the problem into mathematical expressions and then we must solve the resulting system. We need three equations that describe the quantities of 50 peso, 200 peso and 500 peso bills:

<em>y = x - 5</em>     (1)

<em>0.5 · y =</em> <em>z</em>    (2)

<em>x + y + z = 6250</em>     (3)

The solution of the system of <em>linear</em> equations is described below:

<em>x =</em> 2503, <em>y =</em> 2498, <em>z =</em> 1249

For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso. \blacksquare

Find the value of 0.34 * 9
Julli [10]
3.06; lining it up 4*9= 36, write the 6 and carry the 3, then 9*3= 27, add 3 and you get 30. Since in your original problem you have two places behind the decimal point you do the same with your answer so that 306 turns into 3.06

A city has cone shaped buildings for storing salt and sand for icy roads. Each building has a radius of 50 feet and a height of
aalyn [17]

Answer:

  • Radius=50 ft
  • π=3.14
  • Height=30 ft
  • Volume=?

We know that,

\star \:  \:  \purple{Volume_{(cone)} =\pi {r}^{2}   \frac{h}{3} }

\star \:  \:  \purple{Volume_{(cone)} =3.14 \times  {(50)}^{2}  \times   \: \cancel\frac{30}{3}  \:   }

\star \:  \:   \purple{Volume_{(cone)} = 3.14 \times (50 \times 50) \times 10}

\star \:  \:  \purple{Volume_{(cone)} =3.14 \times 2500 \times 10 }

\star \:  \:  \purple{Volume_{(cone)} =78500 }

Thus,the third option is correct.
