Answer:

.173 seconds or a negataive

Step-by-step explanation:

Your formula would be

h = -16t^2 - 55t + 10

when it hits the ground h = 0

16t^2 + 55t - 10 = 0

t = (-55 ± √3665)/32 = .173 seconds or a negataive

You have a right triangle therefore you can calculate the base as (9tan30)=sqrtof3 over 3
 
Area of triangle 1/2 bh = 1/2(sqrt3 over 3)

(9) As this is just 1 triangle you then need to multiply it by 2

bh = sqrt of 3 over 3 * 9</span><span>

A counter top is 18 feet long and 3 feet wide. What is the area of the counter top in square meters? Use the conversion 1 foot =
podryga [215]

Answer:

Area of the counter top is 5.02\ m^2.

Step-by-step explanation:

Given:

Length of the Counter top = 18 feet

Width of the counter top = 3 feet

We need to find the area of the counter top is square meter;

Solution:

Now we need to find the area of the counter top is square meter.

But given data is in feet so we will first convert feet into meters.

1 foot = 0.305 meter.

So 18 feet = Number of meters in 18 feet.

By Using Unitary method we get;

Number of meters in 18 feet = 18\times 0.305 = 5.49\ m

Length of the Counter top = 5.49 m

Also 3 feet = Number of meters in 3 feet.

Again Using Unitary method we get;

Number of meters in 3 feet = 3\times 0.305 = 0.915\ m

Width of the counter top = 0.915 m

Now we know that;

Area of the counter top can be calculated by multiplying Length of the counter top with width of the counter top.

framing in equation form we get;

Area of the counter top = 5.49\times 0.915 = 5.0233\ m^2

Rounding up to 2 decimals we get;

Area of the counter top =  5.02\ m^2

Hence Area of the counter top is 5.02\ m^2.

I need help with 5 and 6!I WILL MARK YOU BRAINLIEST!!!
AURORKA [14]

Answer:

5 right triangle

6 not a right triangle

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = 13^2

25+144 = 169

160 = 169

This is true so this is a right triangle

15^2 +16^2 = 18^2

225 +256 = 324

481 does not equal 324

This is not a right triangle
