Need help with this
Marrrta [24]

Answer:

law of cosines states c^2=a^2+b^2-2abc

b^2=26^2+24^2-2(26×24)cos 134°

b^2=676+576-1248cos134°

cos134= -0.6946

b^2=1252-12(-0.6946)

12×(-0.6946)= -8.3352

b^2=1252-(-8.3352)

b^2=1252+8.3352

b^2=1260.33

b=√1260.33

b=35.50

Help me !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

So 20% is 1/5 as a percent.

So 1/5 multiplied by 5 equals 5/5, or 1.

So if 1/5 = 6, then 6 multiplied by 5, or 30, must equal 5/5, or 1.

So the total number of dolls in Amyia's doll collection is 30.

Chukwu, Abdul and kunle are to share $142, such that Abdul gets $11.00 less than Chukwu and $7.00 more than Kunle. How much is C
Elena-2011 [213]

Answer:

Chukwu's share is of $57.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

Chukwu's share is x.

Abdul's share is y.

Kunle's share is z.

Chukwu, Abdul and kunle are to share $142

This means that x + y + z = 142

Abdul gets $11.00 less than Chukwu

This means that:

y = x - 11

$7.00 more than Kunle.

This means that:

y = z + 7

So

z = y - 7

z = x - 11 - 7

z = x - 18

How much is Chukwu's share?

We want to find x, so:

x + y + z = 142

x + x - 11 + x - 18 = 142

3x - 29 = 142

3x = 171

x = \frac{171}{3}

x = 57

Chukwu's share is of $57.
