Answer:

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$ and $\sqrt{a}$ × $\sqrt{a}$ = a

Given

$\sqrt{8}$ × $\sqrt{18}$

Simplifying each radical

$\sqrt{8}$ = $\sqrt{4(2)}$ = $\sqrt{4}$ × $\sqrt{2}$ = 2 $\sqrt{2}$

$\sqrt{18}$ = $\sqrt{9(2)}$ = $\sqrt{9}$ × $\sqrt{2}$ = 3 $\sqrt{2}$

Thus

$\sqrt{8}$ × $\sqrt{18}$

= 2 $\sqrt{2}$ × 3 $\sqrt{2}$

= 2 × 3 × $\sqrt{2}$ × $\sqrt{2}$

= 6 × 2

= 12

An Open rectangular tank of length 18 cm and breadth 16 cm contains water to a depth of 13 cm. The water is poured into a cylind

san4es73 [151]

Answer:

Step-by-step explanation

Volume of tank = l* b*h

= 18*16*13

=3744 cubic cm

Volume of cylinder = volume of tank

πr²h = 3744

3.14* (17/2)² * h = 3744

h= 3744 *2 *2/*17*17*3.14

h=16.5 cm

find An Equation Of The Line Containg(3,-4) and Having slope -2.If This Line Contain The Points (a,8) and (5,b) find a and b

ss7ja [257]

Answer:

equation: y=-2x+2

a=-3

b=-8

Step-by-step explanation:

we need to find the equation of the line containing the point (3,-4) and has the slope (m) of -2

slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

we can plug what we know into the equation:

y=-2x+b

we need to find b though

since the point will pass through the point (3,-4) we can subsitute it into the equation to find b

-4=-2(3)+b

-4=-6+b

2=b

the y intercept is 2

so the equation is y=-2x+2

the line also contains the points (a,8) and (5,b)

first, let's find a

a is the x value of the point

we know the value of y (8)

substitute y as 8 and solve for x

8=-2x+2

subtract

6=-2x

-3=x=a

so a is -3

now find b

b is the y value of the point

we know the x value (5)

substitute x as 5 and solve for y

y=-2(5)+2

y=-10+2

y=-8=b

so b is -8

hope this helps!

Share 800 in the ratio 9:7.

bulgar [2K]

Answer:

The numerator '9's share is 450 and the denominator '7's share is 350.

Step-by-step explanation:

Step-1: Add the ratios:

9 + 7
16

Step-2: Divide 800 by the sum of the ratios:

800 ÷ 16
=> 50

Step-3: Multiply 50 with each ratio:

9 x 50 = 450
7 x 50 = 350

Hence, the numerator '9's share is 450 and the denominator '7's share is 350.

Hoped this helped.
