Answer:

n = 14 cm

Step-by-step explanation:

We are required to find the find the value of n.

Since, we have the lines are intersecting in the circle.

So, using the 'Intersecting Chord Theorem', which states that the product of the line segment formed by the intersecting lines are equal.

$4\times n= 8\times 7$

i.e. $4n=56$

i.e. n = $\frac{56}{4}$

i.e. n = 14

Hence, the value of n is 14 cm.

3) You owe $1,842.66 on a credit card at a 14.5% APR. You pay $250.00 at the beginning of the month and put another $250.00 in a

Wittaler [7]

3. Credit Card: (1842.66 - 250) (.145/12) = $19.24

Savings: 250(0.04/12) = $0.83

Difference = 19.24 - 0.83 = $18.41

4. Credit Card: (1842.66 - 500) (.145/12) = $16.22

You will save $18.41 - $16.22 = $2.19 by putting all $500 toward the higher credit card rate.

I bought a box of granola bars at the store that has a volume of 210 cubic centimeters

Naya [18.7K]

Answer:

a and c

Step-by-step explanation:

The volume (V) of a cuboid is

V = lwh ( l is length, w is width, h is height )

The volume is given as 210 cm³

Check each of the dimensions given to determine which give the correct volume

V = 15 × 2 × 7 = 210 ← correct volume

V = 14 × 3 × 7 = 294 ← incorrect volume

V = 7 × 3 × 10 = 210 ← correct volume

Hence a and c could be the dimensions of the box

One of the exterior angles of a triangle is 120° and the

Sidana [21]

Answer:

the angles are 80 degrees and 40 degrees

Step-by-step explanation:

The sum of two opposite interior angles equal to the exterior opposite angle.

so;

4x + 2x = 120

x = 120 / 6

x = 20

4x = 80

2x = 40

Jerry solved the system of equations. x minus 3 y = 1. 7 x + 2 y = 7. As the first step, he decided to solve for y in the second

Reika [66]

Answer:

A. The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.

Step-by-step explanation:

Given

$Equation\ 1: x - 3y = 1$

$Equation\ 2: 7x + 2y = 7$

Required

Efficient way of solving the equations

The efficient way of solving this problem is by solving for x in the first equation because it has a coefficient of 1;

The evidence is shown as follows;

Make x the subject of formula in equation 1

$x = 1 + 3y$

Substitute 1 + 3y for x in equation 2

$7x + 2y = 7$

$7(1 + 3y) + 2y = 7$

Open bracket

$7 + 21y + 2y = 7$

$7 + 23y =7$

Make y the subject of formula

$23y = 7 - 7$

$23y = 0$

Divide both sides by 23

$\frac{23y}{23} = \frac{0}{23}$

$y = 0$

Recall that x = 1 + 3y

Substitute 0 for y in the above expression

$x = 1 + 3(0)$

$x = 1 + 0$

$x = 1$

Solving for y in the second equation will take more steps
