Answer:

Step-by-step explanation:

just add 18.4 degrees and then that will get you to 0 and add 15.7 which will get you to the temperature in the day

Step-by-step explanation:

3×|x + 4| + 2 >= 5

you handle this basically like an equation :

3×|x + 4| >= 3

|x + 4| >= 1

because of the absolute value we have 2 solutions for that :

x + 4 = 1

and

x + 4 = -1

as in both cases the absolute value turns the result into 1.

so,

x + 4 = 1

x = -3

x + 4 = -1

x = -5

so, to satisfy the inequality

x >= -3 or x <= -5

please consider : if the inequality would have been > instead of >=, we would have had to use > and < for the solution.

Answer:

92

Step-by-step explanation:

- ( 2 - 6 )

= - ( - 4 )

= 4

- ( 2 - 6 ) ( 23 )

= 4 x 23

= 92

The evaluation of  - (2- 6) ( 23) is 92

In mathematics, evaluation is a systematic method used in solving expressions. From the given information, we need to first solve the expressions in the brackets before multiplying them together.

From the given information:

= - ( 2 - 6) (23)

= - ( -4) (23)

= 4 × 23

= 92

Total : 864 in²

Step-by-step explanation: there you go

Per hour, they would need to add 147 quarts of the liquid ingredient. When converting to gallons, every 4 quarts is one gallon, so we need to divide 147 by 4.

36.75 Gallons Per Hour

They need to add 39 gallons of ingredients to make the production they desire.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

We know 4 quarts are one gallon.

∴ They would be making (13/4) = 3.35 gallons every 5 minutes Or (3.25/5) = 0.65 gallons per minute.

∴ In an hour or 60 minutes, they would be making (0.65×6) = 39 gallons per hour.

Answer: y=4x+3

Step-by-step explanation: First, lets clean this expression up.

y - 2 = 4(x+1)

Multiply 4 times x and 4 x 1.

y-2=4x+1

add 2 to both sides.

Finally, you get y=4x+3.

Remember that 4 is your m (slope), and b (y-intercept). If you were graph this, it would increase to the right. You graph your intercept 3 on the positive y-axis at (0,3) and since your slope is 4x, you go 4 units up and 1 unit to the right and from there, you get the graph of the given equation.

The position of the kite with the point directly beneath the kite at the same

level with the hand and the hand for a right triangle.

Reasons:

The height of his hands above the ground, h = 2.75 feet

Angle of elevation of the string (above the horizontal), θ = 26°

Length of the string, l = 145 feet

Required:

The height of the kite above the ground.

Solution:

The height of the kite above the ground is given by trigonometric ratios as follows;

[tex]\displaystyle Height \ of \ kite, \, k_h = \mathbf{h + l \times sin(\theta)}[/tex]

Therefore;

[tex]\displaystyle Height \ of \ kite, \, k_h = 2.75 + 145 \times sin(26^{\circ}) \approx \mathbf{66.314}[/tex]
