Your answer is 20

As isosceles triangle has two angles similar

And sum of all angles is 180,
so

80 + 80 = 160
and
180 - 160 is
20
So ur answer is 20

Answer:

50°, 80° and 20° could all be possible angles

Step-by-step explanation:

Given that every triangle has three angles that must add up to 180°, there could be a few different combinations with an isosceles triangle that will add up to 180°.

Since two angles of an isosceles triangle must be the same, then you can have the following combinations:

80° + 80° + x = 180°, or x = 20°

80° + 2x = 180°, or x = 50°

So, the possibilities out of the angles given are 80°, 20° and 50°.

Which function has a range of y<3? y=3(2) y=2(3) O y=-(2)* +3 O y= (2)* - 3

VARVARA [1.3K]

option C is correct.

Step-by-step explanation:

If a function is defined as

$f(x)=a^x$ where, a>0, then the range of the function is greater than 0.

$a^x>0$ .... (1)

Option A: Using inequity (1),

$2^x>0$

Multiply both side by 3.

$3(2^x)>0$

The range of first function is y>0. Therefore option A is incorrect.

Option B: Using inequity (1),

$3^x>0$

Multiply both side by 2.

$2(3^x)>0$

The range of second function is y>0. Therefore option B is incorrect.

Option C: Using inequity (1),

$2^x>0$

Multiply both side by -1.

$-2^x$

Add 3 on both the sides.

$-2^x+3$

$y$

The range of first function is y<3. Therefore option C is correct.

Option D: Using inequity (1),

$2^x>0$

Subtract 3 from both the sides.

$2^x-3>-3$

$y>-3$

The range of second function is y>-3. Therefore option D is incorrect.

Jon is paid $20 to mow his neighbor's yard. It takes three hours to mow and $2 worth of gasoline. How much does Jon earn per hou

noname [10]

Jon earns 6 dollars per hour.

We know this because, if he gets paid $20 and buys $2 worth of gasoline, his profit is $18.

Then, we divide 18 by the number of hours he worked, 3, and thus, Jon earns $6/hr.

Answer:

1500 calories

Step-by-step explanation:

2400 is 100% of in this case, 8/8

So then we know that 1/8 of 2400 is 300 because we just divide it by 8. Sarah eats 5/8 that much so we multiply 300 by 5 which gives us 1500
