Answer:

The area of triangle is <u>28 ft²</u>.

Step-by-step explanation:

Here's the required formula to find the area of triangle :

$\star{\underline{\boxed{\sf{Area_{(\triangle)}= \dfrac{1}{2}bh}}}}$

$\purple\star$ △ = Triangle
$\purple\star$ b = base area
$\purple\star$ h = height

Substituting all the given values in the formula to find the area of triangle :

${\implies{\sf{Area_{(\triangle)}= \dfrac{1}{2}bh}}}$

${\implies{\sf{Area_{(\triangle)}= \dfrac{1}{2} \times b \times h}}}$

${\implies{\sf{Area_{(\triangle)}= \dfrac{1}{2} \times 7 \times 8}}}$

${\implies{\sf{Area_{(\triangle)}= \dfrac{1}{\cancel{2}} \times 7 \times \cancel{8}}}}$

${\implies{\sf{Area_{(\triangle)}= 1 \times 7 \times 4}}}$

${\implies{\sf{Area_{(\triangle)}=7 \times 4}}}$

${\implies{\sf{\underline{\underline{Area_{(\triangle)}=28 \: {ft}^{2}}}}}}$

Hence, the area of triangle is 28 ft².

Chip and dale are driving in a toy engine around the Christmas tree at a speed of 300 miles/hour. how many minutes will it take

Deffense [45]

Using proportions, it is found that it will take them 0.00248548 minutes to do one loop.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, according to their speed, in 60 minutes, they drive 300 miles. In how many minutes will they drive 20 m = 0,0124274 miles?

The <em>rule of three</em> is:

60 min - 300 miles

x min - 0.0124274 miles

Applying cross multiplication:

$300x = 60 \times 0.0124274$

$x = \frac{60 \times 0.0124274}{300}$

$x = 0.00248548$

It will take them 0.00248548 minutes to do one loop.

A car dealership sells suv's and passenger cars. For a recent year, 90 more suv's were sold than passenger cars. If a total of 5

Lunna [17]

Answer:

300 SUVs were sold.

210 Passenger cars were sold.

Step-by-step explanation:

Let S denote the amount of SUVs sold and let P denote the amount of passenger cars sold.

The total amount of vehicles sold was 510, so:

$S+P=510$

90 more SUVs were sold than passenger cars. In other words:

$S=90+P$

We know have a system of equations. We can solve it buy substituting the second equation into the first. Thus:

$90+P+P=510$

Combine like terms:

$2P+90=510$

Subtract 90 from both sides:

$2P=420$

Divide both sides by 2:

$P=210$

So, the 210 passenger cars were sold.

This means that 210+90=300 SUVs were sold.

And we're done!

The area of the equilateral, isosceles and right angled triangle are 12.6mm², 9.61in² and 16.81yds² respectively.

<h3>What is the area of the equilateral, isosceles and right angle triangle?</h3>

Note that:

The area of an Equilateral triangle is expressed as A = ((√3)/4)a²

Where a is the dimension of the side.

The area of an Isosceles triangle is expressed as A = (ah)/2

Where a is the dimension of the base and h is the height.

The area of a Right angled triangle is expressed as A = (ab)/2

Where a and b is the dimension of the two sides other than the hypotenuse.

For the Equilateral triangle.

Given that;

a = 5.4mm
Area A = ?

A = ((√3)/4)(5.4mm)²

A = ((√3)/4)( 29.16mm² )

A = 12.6mm²

Area of the Equilateral triangle is 12.6mm²

For the Isosceles triangle.

Given that;

Base a = 3.4in
Slant height b = 5.9in
height h = ?
Area A = ?

The height h is the imaginary line drawn upward from the center of a.

First, we calculate the height using Pythagorean theorem

x² = y² + z²

Where x = b = 5.9in, y = a/2 = 3.4in/2 = 1.7in, and z = h

(5.9in)² = (1.7in)² + h²

34.81in² = 2.89in² + h²

h² = 34.81in² - 2.89in²

h² = 31.92in²

h = √31.92in²

h = 5.65in

Now, the area will be;

A = (ah)/2

A = (3.4in × 5.65in )/2

A = 19.21in²/2

A = 9.61in²

Area of the Isosceles triangle is 9.61in².

For the Right angled triangle

Given that;

a = 8.2yds
b = 4.1yds
c = 9.17yds
Area A = ?

A = (ab)/2

A = ( 8.2yds × 4.1yds)/2

A = ( 33.62yds²)/2

A = 16.81yds²

Area of the Right angled triangle is 16.81yds²

Therefore, the area of the equilateral, isosceles and right angled triangle are 12.6mm², 9.61in² and 16.81yds² respectively.
