9. What formula could be used to find the area of the image?

Scilla [17]

Answer:

9. Area of triangle= $\frac{1}{2} \times base\times height$

10. Base= 16 ft and Height= 15 ft.

11. 120 ft²

Step-by-step explanation:

Given: Base of triangle= 16 ft

Length of leg of triangle= 17 ft.

As shown in the picture that median has bisected the triangle and forming two right angle triangle.

∴ Each base of right angle triangle= $\frac{16}{2} = 8\ feet$

Now, finding the height of triangle by using pythagorean theorem.

We know, $h^{2} = a^{2} +b^{2}$ , where h is hypotenous, a is height or opposite and b is base or adjacent of triangle.

⇒ $17^{2}= a^{2} + 8^{2}$

⇒ $289= a^{2} + 64$

Subtracting both side by 64

⇒ $225= a^{2}$

taking square root on both side, remember; √a²=a

⇒a= $\sqrt{225} = 15$

Hence, height of triangle is 15 ft.

Next, finding the area of triangle.

Formula; Area of triangle= $\frac{1}{2} \times base\times height$

⇒ Area of triangle= $\frac{1}{2} \times 16\times 15$

∴ Area of triangle= 120 ft²

Problem Sathish is going on a 210021002100-kilometer road trip with 222 friends, whom he will pick up 150150150 kilometers after

Novay_Z [31]

Complete question :

Sathish is going on a 2100-kilometer road trip with 2 friends, whom he will pick up 150 kilometers after he begins the trip and drop off when there are 150 kilometer remaining. The car consumes 6 liters of gas for every 100 kilometers, and gas costs $1.20 per liter.

Sathish will pay for all of the gas when he is alone in the car, but he and his friends will split the cost evenly when they are together.

How much will Sathish pay for gas?

Answer:

$64.8

Step-by-step explanation:

Given that :

Total length of trip = 2100 km

Length of journey with Satish alone in the car:

(150km) beginning + (150km) ending = 300km

Length of journey with Satish and 2 friends :

2100 km - 300 km = 1800 km

Gas consumption:

6 liters per 100km

Cost of gas = $1.2 / litre

Consumption when Satish is alone :

(6 litres /100 km) * 300km = 18 litres

Cost = $1.2 * 18 = $21.6

Consumption with his 2 friends :

(6 litres /100 km) * 1800 km = 10800 / 100 = 108 litres

Cost = $1.2 * 108 = $129.6

Since amount is shared equally :

Amount paid by sattish = $129.6 / 3 = $43.2

Hence, total amount paid by Sattish is :

$21.6 + $43.2

= $64.8

it cost a manufacturer $8.75 produce a pair of sunglasses that sells for $29.99. How much must a manufacturer sell to make a pro

Elis [28]

29.99x-8.75x=17884

21.24x=17884

X=841 sunglasses

It actually comes out to be more than 841, but since you can’t make .9 sunglasses then you round to the lower whole number.

How do you describe the sum of two rays for geometry?

Ray Of Light [21]

To find the sum of an infinite geometric series having ratios with an absolute value less than one, use the formula, S=a11−r, where a1 is the first term and r is the common ratio.
