Consider in the figure below.

yawa3891 [41]

Here BD is perpendicular bisector

UB=BV=74

$\\ \tt\hookrightarrow UV=74+74=148$

Apply Pythagorean theorem

$\\ \tt\hookrightarrow BD^2=UD^2-UB^2=UD^2-VD^2$

UD=VD=78=TD

$\\ \tt\hookrightarrow TC^2=TD^2-CD^2$

$\\ \tt\hookrightarrow TC^2=78^2-30^2$

$\\ \tt\hookrightarrow TC^2=6084-900=5184$

$\\ \tt\hookrightarrow TC=72$

A model car is 8 inches long and 5.2

Sphinxa [80]

Use proportions here - 8/5.2 = 96/width of actual car. using cross multiplication, 5.2*96 = 8x. this gives you 499.2 = 8x. divide both sides by eight to get x=62.4. the width of the actual car is 62.4 inches.

A piece of toast came out of the toaster very overcooked.

Nikitich [7]

Answer:

It is a chemical change ⇒ 1st answer

Step-by-step explanation:

* Lets explain the statements to solve the problem

- A chemical change occurs when a new substance is formed through

a chemical reaction

- Ex: cooking an egg

- Change of reaction is the rate of reaction it can be decreases or

increasing

- A phase change is a change from one state to another without a

change in chemical composition

- Ex: Condensation: the substance changes from a gas to a liquid

- A physical change, such as a state change or dissolving, but does

not create a new substance

- Ex: Breaking a glass

* Lets solve the problem

- A piece of toast came out of the toaster very overcooked.

∵ It is like the cooking an egg

∴ It is a chemical change
