Fill 350 milliliter bottles from a 30 liter drum how many bottles

Mathematics

1 answer:

Mama L [17]3 years ago

6 0

Answer:

Step-by-step explanation:

0.350 L × n = 30 L . . . . . where n is the number of bottles.

Divide by 0.350:

n = (30 L)/(0.350 L) ≈ 85.7

85 bottles can be filled, and one can be partially filled.

_____

Of course, you know the SI prefix milli- means 1/1000, so 350 mL = 350/1000 L = 0.350 L. When you do the division indicated above, ...

(30 L)/(0.350 L)

the units of liters cancel, and you are left with the number of bottles.

A triangular pyramid has a height of 18 yards and a base with an area of 330 square yards. What is the volume of the pyramid?

WITCHER [35]

Answer:

option C. $V=1,980\ yd^{3}$

Step-by-step explanation:

we know that

The volume of the triangular pyramid is equal to

$V=\frac{1}{3}Bh$

where

B is the area of the triangular base

h is the height of the pyramid

In this problem we have

$B=330\ yd^{2}$

$h=18\ yd$

substitute in the formula

$V=\frac{1}{3}(330)(18)=1,980\ yd^{3}$

Find the with of a triangle as a 15 cm high in a hypogynous of a 19 cm

Inessa05 [86]

Answer:

This other side of the triangle is equal to about 11.7 cm

Step-by-step explanation:

In order to find out the third side of the triangle we will just use the Pythagoras Theorem.

$c^{2} =a^{2} + b^{2}$

Since we know the hypotenuse and we know one of the legs, in order to find the second leg we just substitute the values and solve the equation and so we get...

$c^{2} =a^{2} + b^{2}\\19^{2} = 15^{2} + b^{2}\\361 = 225 + b^{2} \\$

$b^{2} = 361 - 225\\b^{2} = 136\\b = \sqrt{136} \\$

And so b ≈ 11.66190
