I believe by using
a ^{2}  + b ^{2}  = c ^{2}   \:  \:  \:  \:  \: you \: will \: plug \: in \: 1 \: for \: a \: and \: b \: then \: find \: the \: square \: root \\you will plug in 1 for A and B then you will find the square root of the number you get after you square A and B and add them together. then you should have your answer

What is the value of k in the equation 2/7(k+5/8)=2 2/7
shusha [124]
2/7 ( k+5/8) = 2 and 2/7

2/7 (k+5/8) = 16/7     |multiply by 7

2(k+5/8) = 16     |divide by 2

k+5/8 = 8     |subtract  5/8

k=8-5/8 = 7 and 3/8 = 27/8 = 7.375

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 5 large boxes and 6 small boxes has a t
Olin [163]

Answer:

  • large: 18.5 kg
  • small: 15.75 kg

Step-by-step explanation:

Let b and s represent the weights of the big and small boxes, respectively. Then the two delivered weights can be summarized as ...

  5b +6s = 187

  3b +2s = 87

We can eliminate the "s" variable by subtracting the first equation from 3 times the second:

  3(3b +2s) -(5b +6s) = 3(87) -(187)

  4b = 74 . . . . . collect terms

  b = 18.5 . . . . . divide by 4

Using this value in the second equation, we find ...

  3(18.5) +2s = 87

  2s = 31.5 . . . . . . . . subtract 55.5

  s = 15.75 . . . . . . . . divide by 2

The large box weighs 18.5 kg; the small box weighs 15.75 kg.

I need help with these questions(see image). <br><br>Please show workings.​
worty [1.4K]

Answer:

see explanation

Step-by-step explanation:

(a)

The angle around the centre O of the circle = 360°, then

∠ AOB = 360° - 260° = 100°

Δ AOB is isosceles ( the radii OA and OB are congruent )

The altitude from O bisects ∠ AOB , thus

y = 50°

Since the triangle is isosceles the 2 base angles are congruent, so

x = \frac{180-100}{2} = \frac{80}{2} = 40°

(b)

∠ POR = 360° - 254° = 106°

Δ POR is isosceles (the radii OP and OR are congruent ) , then

the 2 base angles are congruent , thus

a = \frac{180-106}{2} = \frac{74}{2} = 37°
