Suppose the base and height are each multiplied by 1/2 what effect should this have on the area

2 answers:

It would be 1/4 of the original area, as you have just multiplied by 1/2 twice. 1/2 times 1/2 equals 1/4.

Answer:

Simple answer: it will become 1/4 the size that it was.

Step-by-step explanation:

Let the base = b

Let the height = h

Area = 1/2 b*h

Now half both of them.

Area = 1/2 (1/2 b)(1/2 * h)

Area = 1/2 (1/4)*b*h

That quarter should convince you that the area is now 1/4 what it was before the base and height were cut in half.

The equations below represent the numbers y of tickets sold after x weeks for two different local music festivals.

kiruha [24]

Answer:

Part a) 3.5 weeks

Part b) 185 tickets

Step-by-step explanation:

Part a) After how much time have the same number of tickets been sold for both festivals?

Let

x -----> the number of weeks

y ----> the number of tickets sold

we have

Country Music Festival

$y=10x+150$ ----> equation A

Pop Music Festival

$y=20x+115$ ----> equation B

Equate equation A and equation B

$20x+115=10x+150$

solve for x

$20x-10x=150-115$

$10x=35$

$x=3.5\ weeks$

Part b) What is the number of tickets sold at that time?

substitute the value of x=3.5 weeks in the linear equation A or linear equation B

$y=10(3.5)+150$

$y=35+150$

$y=185\ tickets$

ABC is an eqilateral triangle with sides 10cm find the length of the prependicular from A to BC

il63 [147K]

All sides are equal in an equilateral triangle and the perpendicular bisects the side too.

so BC will be bisected and the segments be 5 each.

you can use Pythagoras theorem to find the altitude length, hypotenuse will be one side of the triangle.

$5^2+h^2=10^2$

$h^2=100-25=75$

$h=\sqrt{75}=5\sqrt3$

What is tan 30°? 60' 2 1 90 30"

Lemur [1.5K]

Answer:

Option F. 1/√3

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle θ = 30°

Opposite = 1

Adjacent = √3

The value of Tan 30° can be obtained as illustrated below:

Tan θ = Opposite / Adjacent

Tan 30 = 1/√3

Thus, the value of Tan 30° is 1/√3
