Please awnser questions, no links, no I dont know
Mrac [35]

Answer:

330cm

Step-by-step explanation:

The formula to find the surface area of a rectangular prism is 2(lh+hw+lw)

(lh) in this formula is length times height

(hw) is height times width

(lw) is length times width

To find the answer to this problem lets make the height 3/5cm the width 10cm and the length 15cm

so now you would do (15*3/5) which is 9. This solve (lh)

then you would find (3/5*10) which is 6. This solves (hw)

and lastly you would find (15*10) which is 150. This solves (lw)

Now that you now the value of each one of these you replace it in the equation as so: 2(9+6+150)

now you solve the brackets which leaves us with 2(165)

now you multiply 2 with 165

and the answer is 330cm

Surface area = 330cm

Find the x will name brainlist

\huge \boxed{\mathbb{QUESTION} \downarrow}

  • Find x.

\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}

To solve these type of problems you need to use the pythagoras theorem ⇨ Hypotenuse² = Base² + Altitude².

Here,

  • Altitude = 1.6 cm.
  • Base = 1.2 cm
  • Hypotenuse = x

Now, let's solve for x.

Hypotenuse² = Base² + Altitude²

x² = (1.2)² + (1.6)²

x² = 1.44 + 2.56

x² = 4

x = √4

x = <em><u>2</u></em><em><u>.</u></em>

  • So, the value of x is <em><u>2</u><u> </u><u>cm.</u></em>

<h3><u>NOTE</u><u> </u><u>:</u><u>-</u></h3>
  • Pythagoras theorem can be used only in the cases of right-angled triangles. Here, it's given that the triangle is right angled so we can use this theorem.
  • To solve the squares if decimals, take them as whole numbers & then just add the decimal points. For example, ⇨ for (1.2)², take it as 12² , then multiply 12 by 12, you'll get 144. Now, add the decimal place accordingly ⇨ 1.44 . So, (1.2)² = 1.44.

Jennifer has run many marathons and keeps track of all of her finishing times. At a marathon last month, she finished in 350 min
suter [353]

Answer:

16%

Step-by-step explanation:

406 / 350 = 1.16

406 is 116% of 350

so 350 + 16% is 406

because 350 * 0.16 = 56

56 is 16%

350 + 56 = 406
