Answer:

g(-0.5) = -1

g(0.2) = 0

g(0.5) = 1

Step-by-step explanation:

We are given the value of g(x) for which the x is defined.

Solving

g(-0.5) = -1

As given g(x) = -1 if -1.5 ≤ x ≤ 0.5

g(0.2) = 0

As given g(x) = 0 if -0.5 < x < 0.5

g(0.5) = 1

As given g(x) = 1 if 0.5 ≤ x < 1.5

The biggest among three numbers is 2.4 larger than the smallest one. If 15 times the smallest one is equal to 12 times the secon
g100num [7]

Answer:

18

Step-by-step explanation:

Let x represent smallest number and y represent second number.

We have been given that the biggest among three numbers is 2.4 larger than the smallest one. So biggest number would be x+2.4.

We are also told that 15 times the smallest one is equal to 12 times the second and 10 times the third. We can represent this information in equations as:

15x=12y...(1)

15x=10(x+2.4)...(2)

Upon solving 2nd equation, we will get:

15x=10x+24

15x-10x=10x-10x+24

5x=24

x=\frac{24}{5}

x=4.8

Therefore, the smallest number is 4.8.

The biggest number would be x+2.4\Rightarrow 4.8+2.4=7.2.

Upon substituting x=4.8 in equation (1), we will get:

15(4.8)=12y

72=12y

y=\frac{72}{12}

y=6

Therefore, 2nd number would be 6.

Let us find sum of all numbers as:

4.8+6+7.2=18

Therefore, the sum of all 3 numbers would be 18.

Length of DA: 90°
They are placed on a obtuse angle, which is 180° and DA are also placed on a right angle, so that means 180°-90°=90°

Length of AB: 180°
Their placed on a obtuse angle, therefore it will just be 180°

ADF=BDE because, both of them are right angles. This means their degrees will equal (90°=90°).

Hopefully this helps, sorry if I turn out to be wrong!

an apple orchard contains a hundred and twelve trees the number of trees in each row is 2 less than twice the number of rows fin
san4es73 [151]
Let x be the number of rows and y be the number of trees per row.

x* y = 112
and y =  2x - 2
from first equation  y = 112/x
so  112/x = 2x - 2
112 = 2x^2 - 2x
2x^2 - 2x - 112 = 0
x^2 - x - 56 = 0
(x - 8)(x + 7) = 0
x = 8 , - 7   (ignore the negative)
so the number of rows = 8 
and number of trees per row = 112/8 = 14

Answer number of rows = 8 and number trees i each row = 14.
