Answer:
x > - 7
Step-by-step explanation:
Given
- 3x < 21
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x > - 7
The solution of inequality - 3x < 21 is,
⇒ x > - 7
We have to given that,
The inequality is,
⇒ - 3x < 21
We can simplify the inequality as,
⇒ - 3x < 21
Divide 3 both side,
⇒ - 3x /3 < 21 / 3
⇒ - x < 7
Take - 1 as common,
⇒ - x < 7
⇒ x > - 7
Therefore, The solution of inequality - 3x < 21 is,
⇒ x > - 7

Eleanor must earn at least 70 points for her book report project. So far on the rubric she has 54 points. Write and solve an inequality to show how many points Madeline needs.
Answer:
[tex]x + 54\ge 70[/tex]
[tex]x \ge 16[/tex]
Step-by-step explanation:
Given
[tex]Total = 70[/tex] (at least)
[tex]Accumulated = 54[/tex]
Required
Express as an inequality
In inequalities, at least means [tex]\ge[/tex]
So, the expression is:
[tex]x + Accumulated \ge Total[/tex]
Where x represents the additional points
[tex]x + 54\ge 70[/tex]
Solve for x
[tex]x \ge 70 - 54[/tex]
[tex]x \ge 16[/tex]
Hence, she needs at least 16 points

Zoe supplies costumes to a number of theater companies. She
recently provided 20 different hats, including 4 fedoras.
Considering this data, how many of the next 30 hats requested
from Zoe's inventory should you expect to be fedoras?
Answer:3
Step-by-step explanation:
The 6 fedoras expect if next 30 hats requested from Zoe's inventory, and She recently provided 20 different hats, including 4 fedoras.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
The ratio of hats to fedoras = 20:4
Let's suppose Zoe's inventory, should expect to x fedoras
20/4 = 30/x
x = 30/5
x = 6
Thus, the 6 fedoras expect if next 30 hats requested from Zoe's inventory, and She recently provided 20 different hats, including 4 fedoras.

Que volumen ocupan 0.8kg de alcohol?¿cual es el peso de este volumen? la densidad del alcohol es 790 kg/m3
Respuesta:
Volumen = 0.0010126 m³
Ancho = 7,84 N
Explicación paso a paso:
Dado que:
Masa, m de alcohol = 0,8 kg
Densidad del alcohol, d = 790 kg / m³
Recordar :
Densidad, d = masa, m / volumen, v
Volumen = masa / densidad
Volumen = 0,8 kg / 790 kg / m³
Volumen = 0.0010126 m³
Peso, W = densidad * aceleración debido a la gravedad * volumen
Ancho = 790 * 9,8 * 0,0010126
W = 7.8395
Ancho = 7,84 N

Order 2.000 D5W IV to infuse over 12 hoursThe drop factor is 15 gtt/. Calculate the rate in gtt / min
Answer:
42gtt/m
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Flow rate in gtt/min = (Total fluid in ml × Drop factor) ÷ (Total hours × 60)
Where, Total fluid in ml = 2,000ml
Drop factor = 15gtt/m
Total hours = 12hours
By putting the following value in the formula, we get
Flow rate in gtt/min = (2,000 × 15) ÷ (12 × 60)
= 30,000 ÷ 720
= 41.67 or 42gtt/m
Jill cuts a piece of cardboard in the shape of a trapezoid.The area of the is 43.5sp cm. If bases are cm and 8.5cm long,what is the height.
Answer:
7.25cm
Step-by-step explanation:
Let the complete question be;
Jill cuts a piece of cardboard in the shape of a trapezoid. The area of the is 43.5sp cm. If bases are 3.5cm and 8.5cm long, what is the height.
Area of a trapezoid = 1/2(a+b)*h
a and b are the parallel sides (bases)
h is the height
Given
a = 3.5cm
b = 8.5cm
A = 43.5 sq.cm
Required
Height h
Substitute the given values into the expression
Area of a trapezoid = 1/2(a+b)*h
43.5 = 1/2(3.5+8.5)*h
43.5 = 1/2 * 12h
43.5 = 6h
h = 43.5/6
h = 7.25cm
Hence the height is 7.25cm
