Work out the area of the triangle.

Mathematics
1 answer:
vichka [17]4 years ago
5 0

Answer:

62.8

Step-by-step explanation:

So, keep in mind that the area of a triangle is equivalent to: 1/2(b)(h) with b being your base and h being your height.

We have our base: 10, and our angle: 105. Now we need to find our height. You don't just have to look at a triangle the way that it's oriented in the problem. Rotate it so that 10cm is at the bottom, and it will be much easier.

From there, you can create a right triangle and draw a line from the top of the triangle straight to the base. Then, you have a right triangle, where you can solve the height, and then plug your answer into the area formula. Further steps are detailed in the picture.

You were billed $17.60 for water usage at a rate of $0.55 per gallon. Three choices are correct ways to calculate the the number
nalin [4]

We know that total bill = rate per gallon times numbers of gallons used

So 17.60 = 0.55 times g

which get match to option (a) this is correct .

Now if we divide both sides by 0.55 we would be getting :

17.60 / 0.55 = g which is slightly different than option (b) ( because it is 55 in option b but actually it should be 0.55) so this one is incorrect .

let us now come back to option (a) 17.6 = 0.55 g

if flip the sides it becomes 0.55g = 17.6 which is same as option c option c is also correct .

Let us now divide both sides of option a by g^2 which makes it

17.6/ g^2 = 0.55 /g or 0.55/g = 17.6 /g^2 which matches only left side of option d but not right side of it so this is also not a correct option

Answer : only (a) and c are correct answer .

ICE Princess25 [194]

Answer:

base x height / 2

I'm guessing 10 and 17 are the base and height

10 x 17 = 170

170 / 2 = 85

85 is the area

Hope this helps

Sadie has mangos and watermelons in a ratio of 91:11. How many mangos does she have if she has 66 watermelons?
snow_lady [41]

Answer:

546 manogoes

Step-by-step explanation:

Sadie has mangos and watermelons in a ratio of 91:11.

We need to find the number of mangoes if she has 66 watermelons.

It means that,

11x = 66

x = 6

So,

Mangoes = 91x

= 91(6)

= 546

Hence, there are 546 mangoes.
