Answer:

Height h = 9 cm

Step-by-step explanation:

Given:

Surface area of cuboid = 102 cm²

Length l = 2 cm

Breadth b = 3 cm

Find:

Height h

Computation:

Surface area of cuboid = 2[lb + bh + hl]

102 = 2[(2)(3) + (3)(h) + (h)(2)]

51 = 6 + 3h + 2h

45 = 5h

Height h = 9 cm

How do u convert a fraction into a decimal

lesya692 [45]

You have to divide the numerator (top number) by the denominator (bottom number). For example, 1/2 is 0.5
However, some end up as never-ending decimals, like 1/3, which converts to 0.333 repeating.

NEED ANSWER ASAP PLEASE WILL GIVE BRAINLIEST An integer n is divided by 2 and the quotient is an even integer. What does this te

Nesterboy [21]

Answer:

$n$ is a multiple of 4

Step-by-step explanation:

Let's think about this.

Even numbers are basically numbers that, when divided by 2, get us an integer.

This means that $n$ must be an even integer.

<em>However,</em>

Every other even number, when divided by 2, gets you an odd integer.

This means that every second even number, $n \div 2$ gets us an even number.

This also means that every time $n \div 2$ is an even number, n will be a multiple of 4 (as $2\cdot 2 = 4$ ).

Test this out with any even number that's a multiple of 4 (all multiples of 4 are even numbers)

Hope this helped!

What is the slope intercept from of the equation of the line that that passes through the points (-3, 2) and (1, 5)

viva [34]

The slope-intercept form of a line:

$y=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\to slope\\\\b\to y-intercept$

We have:

$(-3,\ 2)\to x_1=-3,\ y_1=2\\(1,\ 5)\to x_2=1,\ y_2=5$

Substitute:

$m=\dfrac{5-2}{1-(-3)}=\dfrac{3}{4}$

$y=\dfrac{3}{4}x+b$

Put the values of coordinates of the point (1, 5) to the equation of a line:

$5=\dfrac{3}{4}(1)+b\\\\5=\dfrac{3}{4}+b\qquad|-\dfrac{3}{4}\\\\b=4\dfrac{1}{4}$

Answer: $y=\dfrac{3}{4}x+4\dfrac{1}{4}$
