Someone please help me with this question !!!!
Lyrx [107]

Answer:

34.3 in, 36.3 in

Step-by-step explanation:

From the question given above, the following data were obtained:

Hypothenus = 50 in

1st leg (L₁) = L

2nd leg (L₂) = 2 + L

Thus, we can obtain the value of L by using the pythagoras theory as follow:

Hypo² = L₁² + L₂²

50² = L² + (2 + L)²

2500 = L² + 4 + 4L + L²

2500 = 2L² + 4L + 4

Rearrange

2L² + 4L + 4 – 2500 = 0

2L² + 4L – 2496 = 0

Coefficient of L² (a) = 2

Coefficient of L (n) = 4

Constant (c) = –2496

L = –b ± √(b² – 4ac) / 2a

L = –4 ± √(4² – 4 × 2 × –2496) / 2 × 2

L = –4 ± √(16 + 19968) / 4

L = –4 ± √(19984) / 4

L = –4 ± 141.36 / 4

L = –4 + 141.36 / 4 or –4 – 141.36 / 4

L = 137.36/ 4 or –145.36 / 4

L = 34.3 or –36.3

Since measurement can not be negative, the value of L is 34.3 in

Finally, we shall determine the lengths of the legs of the right triangle. This is illustrated below:

1st leg (L₁) = L

L = 34.4

1st leg (L₁) = 34.3 in

2nd leg (L₂) = 2 + L

L = 34.4

2nd leg (L₂) = 2 + 34.3

2nd leg (L₂) = 36.3 in

Therefore, the lengths of the legs of the right triangle are 34.3 in, 36.3 in

Water is leaking out of a tank at a steady rate the tank started with 75 gallons after 15 hours the tank has 33 gallons of water
Natasha_Volkova [10]

Answer:

The equation will be "y=-2.8 x+75".

Step-by-step explanation:

The given values are:

Started with,

= 75 gallons

After 15 hrs,

Tank has,

= 33 gallons

Now,

The slope will be:

=  \frac{33-75}{15}

=  \frac{-42}{15}

=  -2.8

Thus,

The equation is "y=-2.5x+75".

Convert 7 pounds 3 ounces to
svetoff [14.1K]

7 pounds and 3 ounces equal to 3.27 kg

Step-by-step explanation:

We need to convert 7 pounds and 3 ounces to kilograms.

We know:

1 lb = 16 oz

and 1 kg = 2.2 lb

where lb stands for pounds and oz stands for ounces and kg stands for kilograms.

16\,\,oz = 1\,\,pound\\1\,\,oz = \frac{1}{16} \,\,pound\\3\,\,oz = \frac{1}{16}  * 3\,\,pounds\\3\,\,oz = 0.1875\,\,pounds

So, Total pounds = 7+0.1875 = 7.1875

Now, Converting Pounds to kg

2.2\,\,pounds = 1\,\,kg\\1\,\,pound = \frac{1}{2.2}  \,\,kg\\7.1875\,\,pounds = \frac{1}{2.2} * 7.18757.1875\,\,pounds = 3.27\,\,kg

So, 7 pounds and 3 ounces equal to 3.27 kg
