Please help!!! Intersection of chords use formula a•b=c•d
scoray [572]

Given:

Length of chords of one segment = 11 and 8

Length of chords of other segment = 2 and x

To find:

The value of x.

Solution:

<em>If two chords intersect each other inside a circle, the products of length their segments are equal.</em>

\Rightarrow a \cdot b =c \cdot d

\Rightarrow 11 \cdot 8 =2 \cdot x

\Rightarrow 88 =2x

Divide by 2 on both sides.

$\Rightarrow\frac{88}{2} =\frac{2x}{2}

$\Rightarrow 44 =x

Switch the sides.

$\Rightarrow x=44

The value of x is 44.

Tanisha can drive about 300 miles
REY [17]

Answer:

Tanisha's car uses 7 gallons of gas driving 175 miles.

Step-by-step explanation:

With the information provided, you know that Tanisha can drive about 300 miles between 12-gallon fill-ups and with this you can find the gallons of gas needed to drive 175 miles by writing a proportion using this form:  a/b = c/d.

12/300=x/175

This indicates that 12 is to 300 as x is to 175. We write x because we don't know the gallons needed yet. Now, we have to cross products and solve for x to find the answer:

12*175=300x

2100=300x

x=2100/300

x=7

According to this, the answer is that Tanisha's car uses 7 gallons of gas driving 175 miles.
