Answer:

On Friday: -8°c

On Saturday: Temperature decreases by 8°C

<u> As 8°C is reduced again we need to subtract </u>

⇒ -8 - 8

⇒ -16

We can understand this by counting or looking at a number line

in the number line when the values of a number decreases the number place moves to the left! So we need to move 8 places towards the left from -8 in the umber line

WHICH COULD BE SHOWIN LIKE THIS:

-17,<u>-16,-15,-14,-13,-12,-11,-10, -9,</u>-8,7,-6,-5,-4,-3,-2,-1,0,1,2,3.......

You try counting in the series of numbers i have given above start counting towards the left from -9 as 1 till u reach the 8th value which will be -16

Hope this helps.....

2. Find the measure of angle A to the nearest degree.

pav-90 [236]

Answer:

37°

Step-by-step explanation:

we're going to use cosine rule In calculating for the value of angle A

note that cosine rule can be used when two sides are given with an included angle . from the diagram above, the two sides given are side AB and side AC and the included angle is A

Hence cosine rule

a^2 = AB^2+AC^2 - 2AB×AC Cos A

3.2^2= 2.1^2+4.6^2-2×2.1×4.6COSA

10.24 =4.41+21.16- 19.32 COSA

10.24 = 25.57-19.32COSA

10.24-25.57= -19.32COSA

-15.33= -19.32COSA

dividing bothsides by - 19.32

COSA= -15.33/19.32

COA= 0.79347826

A = COS^-1 (0.79347826)

A= 37.488

A= 37°

Anybody got any answers?

musickatia [10]

Hey there!

So, what you would do is . . .

$360$ ÷ $4$ . . .

$90$ ÷ $8$ =11.5

$Area=\boxed{\boxed{11.5}}$

Hope this helps.

Pythagorean Theorem with Known Legs

stepan [7]

you're given the pythagorean theorem, which is a^2 + b^2 = c^2.

what you're trying to find is ?, which is the number under the radical.

let's pretend one leg is a and the other is b.

a = 9

b = 10

so let's plug it into the equation. we get 9^2 + 10^2 = c^2

so that equals 81 + 100 = c^2

181 = c^2

so c will equal the square root of 181. therefore, ? = 181.

hope i helped! good luck.

The secret number has a 7 in the ones place. The tens number is an odd number

Lana71 [14]

This really is left up to you as long as you have an odd number in the tens place and a 7 in the ones place. How big (or small) the number is is up to you. As long as it is at least 17, it's pretty much up to you.
