Illusion [34]

Answer:

PB = 1.8

Step-by-step explanation:

PQ = 8 cm, BC = 10 cm and AB = 9 cm

∆ABC is similar to ∆APQ.

Therefore:

$\frac{AB}{AP} = \frac{BC}{PQ}$

Plug in the values

$\frac{9}{AP} = \frac{10}{8}$

Cross multiply

AP × 10 = 8 × 9

AP × 10 = 72

Divide both sides by 10

AP = 7.2

PB = AB - AP

PB = 9 - 7.2

PB = 1.8

Answer:

She needs to score 78 on her next test

Step-by-step explanation:

$\frac{78+60+82+94+88+x}{6}=80$

Collect like terms;

$\frac{402+x}{6}=80$

Multiply both sides by 6;

402 + x = 480

Subtract 402 from both sides;

x = 78
