conjectures math statement 2(x^2+5)=60 what is the reason? 2x^2+10=60 what is the reason? 2x^2=50 what is the reason? x^2=25 what is the reason? x=+ minus 5.

Answers

Answer 1
Answer: 2(x^2+5)=60 to 2x^2+10=60
distributive property (a(b+c)=ab+ac)

2x^2+10=60 to 2x^2=50
property of equality or something like thht (a=a and b=b, so a-b=a-b) and also
 addative inverse (a+-a=0) (added -10 to both sides)

2x^2=50 to x^2=25
propery of euality and multiplicative inverse (a times 1/a=1) and one produce property (1 times a=a)

x^2=25 to x=+/-5
property of equality and something else

Suface areas- cones
wdh

Answers

Answer:

65

Step-by-step explanation:

The slant height of a cone is the length of a segment from the base to the vertext along the surface of the cone.

You can use the given dimenstions as the legs of a right triangle, and the slant heifght is rthe hyopotenuse.

L^2 = r^2 + h^2

L^2 = 5^2 + 12^2

L^2 = 169

L = 13

The slant heiht is 13 cm.

LA = (pi)rL

LA = (pi)(5 cm)(13 cm)

LA = 65(pi) cm^2

Benson has a bankruptcy on his credit report, so he pays higher interest rates on his current loans. He calculates that the extra money he pays in additional interest each year, if invested at the rate of 2% for one year, could earn him simple interest totaling $180. How much does Benson pay in additional interest each month?

Answers

Given:
Interest = 180
term = 1 year
Interest rate = 2%

We need to get the principal amount using the simple interest formula.

Interest = Principal * interest rate * term
180 = P * 2% * 1
180 / 2% = P
9,000 = Principal

Benson pays an additional interest of  9,000 each year. A monthly payment of 750.

9,000 / 12 months = 750 per month.

Based on the amount that Benson could earn if he invested the additional interest for one year, the additional interest per month is $750.

What additional interest is Benson paying?

This can be found by the formula:

= (Simple interest amount earned / Number of months in year) / Simple interest rate

Solving gives:

= (180 / 12) / 0.02

= 15 / 0.02

= $750

- Mariana debe tomar dos pastillas; una cada 6 horas y otra cada 9 horas. Si a cierta hora toma las dos pastillas juntas, ¿después de cuantas horas volverá a tomarlas simultáneamente?

Answers

Answer:

Mariana takes the two pills together after 18 hours.

Step-by-step explanation:

Mariana must take two pills; one every 6 hours and another every 9 hours.

She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.

To find the time to take the two pills together, take the least common multiple of 6 and 9.

6 = 2 x 3

9 = 3 x 3

So, the least common multiple is 2 x 3 x 3 = 18

So, she takes the two pills together after 18 hours.

How do i find the slope of a line that passes through a given point and is parallel or perpendicular to another given point?

Answers


There's no such thing as parallel or perpendicular "to a point".  A problem like that
will always want the new line to be parallel or perpendicular to another line.

-- If the new line is parallel to the given line, then they have the same slope.

-- If the new line is perpendicular to the the given line, then the slope of the
new line is [ 1 / slope of the given line ].

In either case, you now have the slope of the new line and a point on it. 
From there, you should have no trouble finding its equation.


Parallel is same slope.
Perpendicular is same slope but you have make it opposite and flip it.
For example if your slope is 2/3. For Perpendicular it would be - 3/2.
