The lateral surface area of the cuboids whose dimensions are Length = 22cm, breadth = 12 cm
and height = 7.5 cmn is​

Answer:

20

Step-by-step explanation:

x = price

y = number of keyboard

xy = 540

(x-2)(y+3) = 540

x = 540/y

==> x = 20

==> y = 27

Answer:

44

Step-by-step explanation:

1) we know that opposite sides of a parallelogram are congruent so

4x+28=10x+4

2) subtract 4 on both sides

4x+24=10x

3)subtract 4x on both sides

24=6x

4)divide by 6 on both sides

4=x

5)substitute for x

length of RS =10(4)+4

length of RD=44

The length of the side RS of the parallelogram PQRS is 44.

Given,

As we know in a parallelogram, the opposite sides are parallel and equal. So, in this case, side PQ is equal to side RS.

Computation:

[tex]\begin{aligned}\text{Side RS}&=\text{Side PQ}\\10\text{X}+4&=4\text{X}+28\\10\text{X}-4\text{X}&=28-4\\6\text{X}&=24\\\text{X}&=4\end{aligned}[/tex]

When the value of X is determined to be 4.

By using the substitution method the value of X will be used in the side RS to determine the length of RS.

[tex]\begin{aligned}\text{RS}&=10\text{X}+4\\&=(10\times4)+4\\&=40+4\\&=44\end{aligned}[/tex]

Therefore, the length of RS is 44.

Answer:

-0.0714 approx

Step-by-step explanation:

78x − 12 = 316x + 5

Bring all the like terms together

78x -316x = 5 + 12

-238x = 17

∴ x = 17 ÷ -238 = -0.0714 (rounded up to 3 significant figures)

Answer:Percent Increase n the number of parts usually made = 80%

Step-by-step explanation:

Percent Increase = (Increase / Initial Number of parts made daily)  X 100/1

Initial Number of parts made daily = 45

Current number of parts ,made daily = 81

Percent Increase = 81-45/ 45 x 100

=36/45 x100/1

= 0.8 x 100

= 80%

Answer:

80 percent

Answer:

You are selecting marbles with replacement. The marble selections (trials) are independent and the marble selection follows the binomial distribution.

The probability of selecting a red marble the first time is 1313.

(This is because 4 out of 12 marbles are red and412412 reduces to 1313.

The probability of selecting a red marble the second time is 1313.

The marble selections are independent and you can multiply the two probabilities to get the following:

probability of getting 2 reds = (13)2(13)2

=19=19.

So the probability of getting two reds is 1919.

Answer:

F

Step-by-step explanation:

To figure out if a set of angles are in a triangle, make sure they add up to 180

F) 58,70,62                 58 + 70 + 62 = 190      This option is incorrect

G) 41,68,71                   41 + 68 + 71 = 180       This option is correct

H) 68,60,52                68 + 60 + 52 = 180    This option is correct

J) 73,42,65                  73 + 42 + 65 =  180     This option is correct

Since option F did not equal 180, F is the answer.

Step-by-step explanation:

...

Step-by-step explanation:

We know that the formula for slope is y=mx+b, with m equaling the slope itself and b equaling the y-intercept. Since the slope is -4, we can safely say that the equation starts off as y=-4x.

The y-intercept is (0,2). This means that the x-coordinate is 0 and the y-coordinate is 2, so the y-intercept is 2. Since 2 is being added, the equation is y=-4x+2

Answer:

y=-4x+2
