I need help with 5,6,7 please
AlladinOne [14]

Answer:

see explanation

Step-by-step explanation:

the arc length of a circle is calculated as

arc = circumference of circle × fraction of circle

(5)

circumference (C) is calculated as

C = 2πr ( r is the radius )

here diameter = 12 , then r = 12 ÷ 2 = 6

C = 2π × 6 = 12π ≈ 37.7 m ( to the nearest tenth )

(6)

JK = 2πr × \frac{75}{360}

    = 2π × 7 × \frac{5}{24}

    = 14π × \frac{5}{24}

    = \frac{14\pi (5)}{24} ≈ 9.2 in ( to the nearest tenth )

(7)

7.5 = 2πr × \frac{120}{360}

7.5 = 2πr × \frac{1}{3} ( multiply both sides by 3 to clear the fraction )

22.5 = 2πr ( divide both sides by 2π )

r = \frac{22.5}{2\pi } ≈ 3.6 ft

Help this type of work confuses me
Dmitrij [34]

Answer/Step-by-step explanation:

Given:

-x + 3x + 1 + 4(x + 2) = 54

To solve, first open the bracket by applying the distributive property. Multiply every term you have in the bracket by 4

-x + 3x + 1 + 4x + 8 = 54

Add like terms together

6x + 9 = 54

Subtract 9 from each side

6x = 54 - 9

6x = 45

Divide both sides by 6

x = 45/6

x = 7.5

Solve the equation x/4+5/8=3/8
tia_tia [17]

X/4 +5/8 = 3/8

X/4 = 3/8-5/8

X/4 = (3-5)/8

X/4 = -2/8

Multiply both sides by 4 we get

4x/4 = -8/8

X = -1
