A car travels at 65 miles per hour. Going through construction, it travels at 3/5 this speed. Write this fraction as a decimal a

nata0808 [166]

3/5 = 60/100 = 0.6

65
x 60
= 00
3900

3900 / 100 = 39.

While going through construction, the car travels at 39mph.

Secant TP and tangent TR intersect at point 7. Chord SR and chord PQ intersect

Answer:

(C)x=11.6, y=23.2

Step-by-step explanation:

Using Theorem of Intersecting Secant and Tangent

Applying this theorem in the diagram, we have:

$TQ$ X TP=TR^2$

$10(10+x+4)=16^2\\10(14+x)=256\\140+10x=256\\10x=256-140\\10x=116\\$Divide both sides by 10\\x=11.6$

Next, we apply Theorem of Intersecting Chords

PV X VQ=SV X VR

4 X x= 2 X y

Recall earlier we got: x=11.6

2y=4 X 11.6

2y=46.4

Divide both sides by 2

y=46.4/2=23.2

Therefore: x=11.6, y=23.2
