Alonso went to the market With $55 to buy eggs and sugar he knows he needs a package of 12 eggs that cost $2.75 after getting the eggs he wants to buy as much sugar as he can with his remaining money does sugar he likes comes in boxes that each cost $11.50
Answers
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.

4 times a number is 21 less than the square of that number. Find the positive solution
Answers
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.

Answers
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.

Answers
================================================
Explanation:
Let's go through the answer choices
A) This is false because -2 is actually larger than -5. Make a number line and you'll see that -2 is to the right of -5. Numbers on the right are larger than numbers on the left. B) This is also false. The value 0 is smaller than 2. A number line might help show this.C) Also false. It should be 4 > -4. Any positive number is always larger than any negative number. D) This is true. On a number line, -6 is to the left of -5, so -6 is smaller than -5. This makes -6 < -5 a true statement.Which step was the first error made? -3\left(2x-3\right)=33−3(2x−3)=33 -6x+6=33−6x+6=33 step 1 -6x=27−6x=27 step 2 \frac{\left(-6x\right)}{-6}=\frac{\left(27\right)}{-6} −6 (−6x) = −6 (27) step 3 x=-4.5x=−4.5 step 4 Step 3 Step 2 Step 1

Given:
The equation is

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.

A person whose eye level is 11 ft above the ground is looking at a building. The angle of elevation to the top of the building is 22 degrees and the angle of depression to the bottom of the building is 34 degrees. What is the height (in feet) of the building? Round your answer to the nearest foot.
Answers
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.
