The area of a rectangle is x 2 – 3x – 28. If the

length is x + 4, find the width.

Answers

Answer 1

Answer:

-4 square units

Step-by-step explanation:

a = l × b

x2 - 3x - 28 = (x +4)(×)

x2 - 3x - 28 = x2 + 4x

-3x - 28 - 4x = 0

-7x - 28 = 0

-7x = 28

x = -4

The diameter of the sun is about 1.4x10^6 km. The diameter of the planet Mercury is about 5000 km. What is the approximate ratio of the diameter of the sun to the diameter of mercury?

Answers

Answer:

280 : 1

Step-by-step explanation:

Diameter of the Sun

[tex] =1.4\times 10^6\: km\\=1400000 \: km[/tex]

Diameter of Mercury = 5000 km

Ratio of the diameter of the sun to the diameter of mercury

[tex] = \frac{1400000}{5000} \\ = \frac{1400}{5} \\ = \frac{280}{1} \\ = 280 \: : \: 1[/tex]

The approximate ratio of the diameter of the sun to the diameter of mercury will be 280: 1.

What is an expression?

Mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the diameter of the sun is about 1.4x10⁶ km. The diameter of the planet Mercury is about 5000 km.

The ratio will be calculated as:-

Ratio = 1.4x10⁶  / 5000

Ratio = 280 : 1

Therefore, the approximate ratio of the diameter of the sun to the diameter of mercury will be 280: 1.

Jack compares the elevations, in feet, of the first two rest stops by writing the inequality -10 someone plz help me plz​

Answers

Missing Part of Question:

Explain whether the inequality Jack writes is correct or incorrect. In your explanation,  include a description of each value in the inequality in terms of what it represents.

Answer:

Jack is incorrect

Step-by-step explanation:

Given:

Jack representation: [tex]-10 < -15[/tex]

Required

State with reason if Jack is correct or not

Jack representation of both elevation shows implies that -10 is less than -15

This illustration is incorrect because;

If the numbers are presented on a number line

-10 is to the right of -15

And numbers on the number line increases along the right hand side.

Hence;

We can conclude that Jack is incorrect because [tex]-10 > -15[/tex]

If 7n+3=4/3 , what is the value of 7n + 5? Group of answer choice A. -5/21 B. -5/3 C. 13/3 D. 10/3
PLZ help me

Answers

Answer:D-10/3

Step-by-step explanation:

The value of 7n + 5 is 13/3

In order to determine the value of 7n + 5, the first step is to determine the value of n from the first equation given : 7n+3=4/3

7n+3=4/3

Combine similar terms

7n = 4/3 - 3

7n = 1 1/3 - 3

7n = -1 2/3

Divide both sides of the equation by 7

n = -1 2/3 ÷ 7

n = -5/3 x 1/7 = -5/21

Substitute for the value of n in this equation: 7n + 5

7(-5/21) + 5

= -5/3 + 5

= -1 2/3 + 5 = 4 1/3 = 13/3

If a person has the values for an object's density and volume, what value can be calculated? the object's size the object's mass o the shape the object forms in a container O the amount of space the object takes up​

Answers

Answer:

B

Step-by-step explanation:

the objects mass

Density is defined as its mass per unit volume.

If a person has the values for an object's density and volume, the object's mass can be calculated.

What is density?

Density is defined as its mass per unit volume.

We have,

The object's density and volume are known.

Density = Mass / Volume

So, if the density is known its mass and volume are also known.

We need to see which values can be calculated:

The object's size:

We can not calculate the object's size by knowing the volume and mass of the object.

The object's mass:

The object's mass can be calculated by knowing the density of the object.

The shape the object forms in a container:

The shape of the object can not be calculated by knowing the mass and volume of the object.

The amount of space the object takes up​:

The amount of space the object takes up​ can not be calculated by knowing the mass and volume of the object.

Thus,

If a person has the values for an object's density and volume, the object's mass can be calculated.

please mark as the brainliest (ㆁωㆁ)

Answer:

-28

Step-by-step explanation:

Simplifying

3m + 6 + -2m = -22

Reorder the terms:

6 + 3m + -2m = -22

Combine like terms: 3m + -2m = 1m

6 + 1m = -22

Solving

6 + 1m = -22

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + 1m = -22 + -6

Combine like terms: 6 + -6 = 0

0 + 1m = -22 + -6

1m = -22 + -6

Combine like terms: -22 + -6 = -28

1m = -28

Divide each side by '1'.

m = -28

Simplifying

m = -28

Use z scores to compare the given values.

Based on sample​ data, newborn males have weights with a mean of 3259.8 g and a standard deviation of 869.7 g. Newborn females have weights with a mean of 3000.9 g and a standard deviation of 550.8 g. Who has the weight that is more extreme relative to the group from which they​ came: a male who weighs 1600 g or a female who weighs 1600 ​g?

Since the z score for the male is z=__and the z score for the female is z=___​, the

(male or female(which one)has the weight that is more extreme.

Answers

Answer:

The answer is given below

Step-by-step explanation:

Z score is used to measure by how many standard deviations the raw score is above or below the mean. It is given by the formula:

[tex]z=\frac{x-\mu}{\sigma}\\ \\Where\ \mu=mean, x=raw\ score, \sigma=standard\ deviation[/tex]

For the male:

μ = 3259.8 g, σ = 869.7 g

Hence for a male who weighs 1600 g, the z score is:

[tex]z=\frac{x-\mu}{\sigma} =\frac{1600-3259.8}{869.7}=-1.91[/tex]

For the female:

μ = 3000.9 g, σ = 550.8 g

Hence for a female who weighs 1600 g, the z score is:

[tex]z=\frac{x-\mu}{\sigma} =\frac{1600-3000.9}{550.8}=-2.54[/tex]

Since the z score for the male is z= -1.91 and the z score for the female is z= -2.54 the  male has the weight that is more extreme.
