The 3 inside angles of a triangle equal 180.

Add the 3 angles together to equal 180:

X + (5x-20) + 4x = 180

Simplify the left side by adding like terms:

10x-20 = 180

Add 20 to each side:

10x = 200

Divide both sides by 10:

x = 20

Angle A = x = 20

Angle B = 4X = 4(20) = 80

Angle C = 5x-20 = 5(20) -20 = 100-20 = 80

A force of magnitude F stretches a spring a distance of 2 cm from its rest position. What magnitude of force will stretch the sp

SIZIF [17.4K]

Answer:

Step-by-step explanation:

Force = k * x

so k = force/distance = F/2

if you were to duplicate the distance 2 times more, the F must also do so so that it's proportional

so F*2 = 2F but since it says additional 4cm, you will need to add the initial one and this one so that it's 6cm in total.

2F + F = 3F

The mass of the Eiffel Tower is about 9.16 ⋅ 106 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 108 kilograms. Approxim

Answer:

$7.96 *10^8kg$

Step-by-step explanation:

Given

$Eiffel = 9.16 * 10^6\ kg$

$Golden\ Gate =8.05 * 10^8kg$

Required

Determine the difference in mass

This is calculated by subtracting the mass of Eiffel tower from the mass of Golden gate bridge

$Difference = Golden\ Gate - Eiffel$

$Difference = 8.05 * 10^8 - 9.16 * 10^6$

Express $10^8$ as $10^6 * 10^2$

$Difference = 8.05 * 10^2*10^6 - 9.16 * 10^6$

Express $10^2$ as $100$

$Difference = 8.05 * 100*10^6 - 9.16 * 10^6$

$Difference = 805 *10^6 - 9.16 * 10^6$

Factorize:

$Difference = (805- 9.16) * 10^6$

$Difference = 795.84 * 10^6$

Factorize the decimal number

$Difference = 7.9584 *10^2 * 10^6$

$Difference = 7.9584 *10^8$

Approximate:

$Difference = 7.96 *10^8$
