Answer:

  C.)  2×10²

Step-by-step explanation:

  (Sun dia) / (Mars dia) = (1.4 x 10⁶ km) / (0.7 × 10⁴ km) = (1.4/0.7) × 10²

The ratio of diameters is about 2 × 10².

_____

The applicable rule of exponents is ...

  (a^b)/(a^c) = a^(b-c)

__

The diameter of Mars can be expressed several ways.

  7000 = 7×1000 = 0.7×10,000 = 0.7×10⁴

Answer: The mode would be 1

Step-by-step explanation: To find the mode of a set of numbers you need to

put all the numbers in order. Then, you need to count how many of each number you have in the set. And the number that appears the most is the mode.

Answer:

The mode is 1 because it appears the most amount of times

Answer:

Step-by-step explanation:

Let the number be x

by given condition,

4x = (x)² - 21

4x = x²- 21

0 = x² - 4x - 21

0 = x² - 7x + 3x - 21

0 =  x ( x-7) + 3 ( x - 7)

0 = (x+3)(x-7)

hence

x + 3 =0.....

x = -3---------1

x - 7 = 0

x = 7 ------------2

we got value of x from 1 and 2.. but the question says positive value of x.

hence, x = 7 is the required value of x.

Answer:

d. 60

Step-by-step explanation:

[tex](2x + 30) \degree = (4x - 90) \degree \\ (exterior \: alternate \: \angle s) \\ \\ 2x + 30 = 4x - 90 \\ \\ 30 + 90 = 4x - 2x \\ \\ 120 = 2x \\ \\ x = \frac{120}{2} \\ \\ x = 60[/tex]

Answer:

4x+17=5

Step-by-step explanation:

The product of 4 and a number: Product means multiplication.

Therefore, we have 4 and any variable of your choice.(I used x)

plus 17: +17

Now we have 4x+17

Is: means equal (=)

Now we plug in what we have: 4x+17=5

Answer:

0.35

Step-by-step explanation:

To get 7/20 converted to decimal, you simply divide 7 by 20. Don't worry. You don't need to get the calculator out, because we did this for you. 7/20 as a decimal is: 0.35 Note: When Research Maniacs calculated 7/20 as a decimal, we rounded the answers to nine digits after the decimal point.

Answer:

D

Step-by-step explanation:

Given:

Alonso has total amount = $55

Cost of a package of 12 eggs = $2.75

Cost of sugar box = $11.50

To find:

The number of sugar boxes he can buy with the remaining money after buying a package of 12 eggs that cost $2.75.

Solution:

Let the number of sugar boxes he can buy be x.

Total cost of x sugar boxes = $11.50x

Total cost of x sugar boxes and a package of 12 eggs = $(11.50x + 2.75)

The total cost must be less than or equal to $55.

[tex]11.50x + 2.75\leq 55[/tex]

[tex]11.50x\leq 55-2.75[/tex]

[tex]11.50x\leq 52.25[/tex]

Divide both sides by 11.50.

[tex]x\leq \dfrac{52.25}{11.50}[/tex]

[tex]x\leq 4.54348[/tex]

So, the greatest integer value of x is 4.

Therefore, he can buy 4 sugar boxes with his remaining money.

Answer:

The correct option is;

The inverse of the original conditional statement

Step-by-step explanation:

The converse of a conditional statement is given as follows;

Conditional statement: If p then q            [tex]{}[/tex]                                p → q

The converse of the conditional statement: If q then p  [tex]{}[/tex]        q → p

The contrapositive of the conditional statement: If not q then not p  [tex]{}[/tex]        ~q → ~p

Therefore, the conditional statement is logically equivalent to its contrapositive

The inverse of the conditional statement: If not p, then not q  [tex]{}[/tex]        ~p → ~q

Similarly

The converse of the conditional statement is equivalent to the inverse of the conditional statement.

Answer:

b

Step-by-step explanation:

Given:

The equation is

[tex]-3(2x-3)=33[/tex]

The incorrect solution steps are given.

To find:

The first error.

Solution:

We have,

[tex]-3(2x-3)=33[/tex]

Using distributive property, we get

[tex]-3(2x)-3(-3)=33[/tex]

[tex]-6x+9=33[/tex]

The given step 1 is [tex]-6x+6=33[/tex], which is not correct.

Therefore, there is first error in step  1 because the distribution property is not used properly.

Hence, the correct option is D.

Answer:

The building has a height of 14 feet.

Step-by-step explanation:

At first we construct the geometrical diagram respective to the person-building system, whose result can be seen in the attached image. We proceed to describe each variable:

[tex]h[/tex] - Height of the eye level above the ground, measured in feet.

[tex]H[/tex] - Height of the building, measured in feet.

[tex]\alpha[/tex] - Angle of elevation, measured in sexagesimal degrees.

[tex]\beta[/tex] - Angle of depression, measured in sexagesimal degrees.

[tex]r[/tex] - Distance between eye level and the bottom of the building, measured in feet.

[tex]r'[/tex] - DIstance between eye level and the top of the building, measured in feet.

By using trigonometric ratios and functions we find that height of the building is represented by the following formula:

[tex]H = r\cdot \sin \beta + r'\cdot \sin \alpha[/tex] (Eq. 1)

But [tex]r[/tex] and [tex]r'[/tex] can be obtained by these expressions:

[tex]r = \frac{h}{\sin \beta}[/tex] (Eq. 2)

[tex]r' = \frac{r\cdot \cos \beta}{\cos \alpha}[/tex] (Eq. 3)

By (Eq. 2) in (Eq. 3):

[tex]r'= \frac{h}{\cos \alpha \cdot \tan \beta}[/tex] (Eq. 3b)

Now, we expand (Eq. 1) by (Eqs. 2, 3b):

[tex]H = h + h \cdot \tan \alpha \cdot \tan \beta[/tex]

[tex]H = h\cdot (1+\tan \alpha \cdot \tan \beta)[/tex] (Eq. 4)

If we know that [tex]h = 11\,ft[/tex], [tex]\alpha = 22^{\circ}[/tex] and [tex]\beta = 34^{\circ}[/tex], the height of the building is:

[tex]H = (11\,ft)\cdot (1+\tan 22^{\circ}\cdot \tan 34^{\circ})[/tex]

[tex]H = 13.998\,ft[/tex]

The building has a height of 14 feet.
