Value of x in the equation 2(x+3)=4(x-1)?
Answers
Answer:
x = 5
Step-by-step explanation:
In this question, you would solve for x.
Solve:
2(x + 3) = 4(x - 1)
Use the distributive property.
2x + 6 = 4x - 4
Subtract 4x from both sides.
-2x + 6 = -4
Subtract 6 from both sides.
-2x = -10
Divide both sides by -2
x = 5
The value of x is 5.

last week, Haley scored 15 points. Haley increased her points 20% during her game this week compared to last week. How many points did she score this week?
Answers
Answer:
18
Step-by-step explanation:
15 + 20% = 18
If Hailey increased her points by 20%, she would score 18 points this week. Therefore, what we need to do is to multiply 15 by 0.20. How did we get 0.20? Well, we divided 20 by 100 to get 0.20. Anyway, once we have multiplied 15 by 0.20, we get 3. However, this answer would not be logical because she increased her points by 20% - we are going up and not down. So, we add 15 and 3 together to get a total of 18 points scored.

A hot air balloon is rising vertically. From a point on level ground 110 feet from the point directly under the passenger compartment, the angle of elevation to the balloon changes from 25 degrees to 32 degrees. How far, the nearest tenth, does the balloon rise during this period
Answers
Answer:
17.44 ft.
Step-by-step explanation:
Given,
The Distance of the hot air balloon: 110 ft
Change in elevation, [tex]\theta_1 = 25^0, \theta_2 = 32[/tex]
We know that,
[tex]\tan \theta = \dfrac{Perpendicular}{base}[/tex]
Now,
[tex]\tan \theta_1 = \dfrac{h_1}{110}[/tex]
[tex]\tan 25^0= \dfrac{h_1}{110}[/tex]
[tex]h_1 = 51.294\ ft[/tex]
[tex]\tan \theta_2= \dfrac{h_2}{110}[/tex]
[tex]\tan 32^0= \dfrac{h_2}{110}[/tex]
[tex]h_2 = 68.736\ ft[/tex]
Rise of balloon = 68.736 - 51.294
= 17.442 ft
= 17.44 ft
Hence, the rise of the balloon rise is 17.44 ft.

Determine the dimensions of a rectangular solid (with a square base) with maximum volume if its surface area is 529 square meters. Round each dimension to 4 decimal places
Answers
Answer:
[tex]x=23/\sqrt{6}[/tex],
[tex]y= \frac{23}{6\sqrt{6}}[/tex]
Step-by-step explanation:
From the question we are told that
Surface area is 529 square meters
Generally the dimensions of the cuboid
[tex]v=x^y[/tex]
[tex]D=4xy+2x^2 =529[/tex]
[tex]V=x^29(\frac{529-6x^2}{4x})[/tex]
[tex]V' =529-6x^2/4[/tex]
[tex]v'=0[/tex]
Therefore
[tex]529=6x^2[/tex]
[tex]x=\sqrt{\frac{529}{6} }[/tex]
[tex]x=23/\sqrt{6}[/tex]
Mathematically
[tex]v''=\frac{12x}{4}[/tex]
[tex]v''=-3\frac{23}{\sqrt{6} }<0[/tex]
[tex]y= \frac{529-2*(\frac{529}{6} }{4*\frac{23}{\sqrt{6} } }[/tex]
[tex]y= \frac{23}{6\sqrt{6}}[/tex]
Therefore
[tex]x=23/\sqrt{6}[/tex]
and
[tex]y= \frac{23}{6\sqrt{6}}[/tex]
Find the percent increase from 15 to 18
Answers
Answer:
The percentage increase would be 20%
Step-by-step explanation:
worked it out
The percent increase from 15 to 18 is 20%.
To find the percent increase from 15 to 18, we can use the following formula Subtract the initial value from the final value, then divide the result by the absolute value of the initial value.
Percent Increase = (New Value - Old Value) / Old Value * 100
Using this formula, let's calculate the percent increase:
Percent Increase = (18 - 15) / 15 * 100
Percent Increase = 3 / 15 * 100
Percent Increase = 0.2 * 100
Percent Increase = 20
Therefore, the percent increase from 15 to 18 is 20%.
