What is Lcm of 30 and 40

Step-by-step explanation:

m(x + n) = n

mx + mn = n

mx = n - mn

x = (n - mn)/m

x(a + b) = b(c - x)

ax + bx = bc - bx

ax + bx + bx = bc

x(a + b + b) = bc

x(a + 2b) = bc

x = bc/(a + 2b)

mx = n(m + x)

mx = mn+ nx

mx - nx = mn

x(m - n) = mn

x = mn/(m-n)

Answer:

1.

∠DCB is the half of the measure of ∠ACB as the angle bisector DC cut it in two equal parts.

2.

The incenter is the intersection of the angle bisectors.

All three angle bisectors lie inside the triangle, hence the incenter is always inside.

Answer:

x=-5/2,4

Step-by-step explanation:

Answer: 12km

Step-by-step explanation:

To find the missing side you need to use the formula a^2 + b^2 = c^2 where C is your hypotenuse.

So your formula would be 4^2 + 3^2 = c^2 ...

16 + 9 = c^2

25 = c^2 so square root both sides. Your missing side is 5km and then add all sides together to find your perimeter.

Answer:

x=-2

Step-by-step explanation:

5x+4=-6 so basically what you want to do is try to get x by itself

step 1 subtract 4 from each side

5x=-10

step 2 divide each side by 5

x=-2

Answer:

K=24

B=21

Step-by-step explanation:

x+x-5=43

2x=48

x=24

K=24

B=21

Answer:

24

Step-by-step explanation:

So the only way I think would be possible to get the answer is if you divide 43 by 2 (since Bobbie and Kylie are 2 people) then subtract 5 to get the answer?

Answer:

X = 4.47  Y = 8.94

Step-by-step explanation:

2[tex]\sqrt{5}[/tex]= 2.23606798

2.23606798 x 2 = 4.47213596

-------

4.47213596

4.47213596^2 + 4.47213596^2 = 8.94427192^2

8.94427192^2 = 80

Square root of 80 is 8.94

Answer:

The markup formula is as follows: markup = 100 * profit / cost .

Step-by-step explanation:

For example if your cost is $10.00 and you wish to markup that price by 40%, 100% + 40% = 140%. Multiply the $10.00 cost by 140% and get the retail price of $14.00.

How do you calculate a 45 markup?

Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.

Responder:

1,78 cm

Explicación paso a paso:

El área de superficie total de la superficie esférica se expresa como;

T = 4πr² donde

r es el radio

Dado

TSA = 40 cm²

Sustituir

40 = 4πr²

r² = 40 / 4π

r² = 10 / π

r² = 10 / 3,14

r² = 3,185

r = √3,185

r = 1,78

por lo tanto, el radio de la esfera a la centésima más cercana es 1,78 cm

Answer:

16

Step-by-step explanation:

By the property of intersecting chords inside the circle, we have:

[tex](5x - 7) \degree = \frac{1}{2} (119 \degree + 27 \degree) \\ \\ (5x - 7) \degree = \frac{1}{2} \times 146 \degree\\ \\ (5x - 7) \degree = 73\degree \\ \\ 5x - 7 = 73 \\ \\ 5x = 73 + 7 \\ \\ 5x = 80 \\ \\ x = \frac{80}{5} \\ \\ x = 16[/tex]

Answer:

8.48%

Step-by-step explanation:

Bill's weight decreases from 64.8 kg to 59.3 kg.

We need to find the percentage decrease in Bill's weight. It can be calculated as follows :

[tex]\%=\dfrac{64.8 -59.3 }{64.8 }\times 100\\\\=8.48\%[/tex]

So, the required decrease in percentage is 8.48%.

Given:

The sides of a triangles in the options.

To find:

Which of the following cannot be the lengths of the sides of a triangle?

Solution:

In a triangle, the sum of two smaller sides must be greater than the longest side, otherwise it cannot be the lengths of the sides of a triangle.

For option A,

[tex]6+8=14>12[/tex]

For option B,

[tex]4+4=8>12[/tex]

For option C,

[tex]6+6=12[/tex]

Here the sum of two smaller sides is not greater than the longest side. So, the sides 6, 6, 12 cannot be the lengths of the sides of a triangle.

For option D,

[tex]6+8=14>10[/tex]

Therefore, the correct option is C.

Answer:

n =[tex]\frac{5}{10}[/tex]

Step-by-step explanation:

Answer:

n= 2 and two thirds

Step-by-step:

this is the equation

3/10n=4/5

so to get n by itself, you multiply both sides by 10/3. I did 4/5 times 10/3 and I got 2/2/3, or two and two thirds
