Answers

Answer: x = 10

Explanation: The bottom left angle is 90 degrees because of the symbol. ( Make sure you know this for future problems.) The whole triangle needs to add up to 180. This isn’t the right way to solve this kind of problem but I know how to solve it using this way and I know the at 10 is the right answer. The other two angles need to add up to 90 because 90 + 90 = 180. So basically I just substituted the same number into x until I added both outcomes and got 90. I hope you understand that cause I don’t really know how to explain it well. Let me try and show you.

3(x)+5 6(x)-5

Now you have to plug in the same number for x until both numbers add to ninety.

3(5)+5 6(5)-5.

( 5 isn’t the right number for x this is just an example. )

You end up with 20 for the first one, and 25 for the second one. 20 + 25 = 45 and 90 + 45 is only 135. So this means that 5 isn’t the right answer and you need to substitute a higher number in for x.

3(10)+5 6(10)-5

( This is the right setup. )

You end up with 35 for the first one and 55 for the second one after you distribute and solve. Now you have 35 and 55. 35 + 55 = 90 and 90 + 90 = 180. This is how you know that you are right. I hope this helps. :)

The table shows the highest and lowest golf scores for your cousin and your friend over the summer. Find the ranges of golf scores for your cousin and your friend. Who has the greater range of scores?

highest +6, +3
lowest -2, -3

Answers

Answer:

Cousin has a greater range of score.

Step-by-step explanation:

Range = Highest No. - Lowest No.

Range of cousin's score = +6 - (-2)

                                        = +6+2 = 8

Range of friend's score = -2 - (-3)

                                       = -2 + 3  = 1

Cousin has a greater range of score.

Which equation has a slope of -2 and passes through the point (1,-6)?
A. y=-2x-4
B. y=-10x+3
C. y=3x-10
D. y=3x+10

Answers

Answer:

y=-2x-4

Step-by-step explanation:

Given that,

Slope, m = -2

It passes through the point (1,-6).

We need to find the equation of line that passes throgh the given point. It can be calculated as:

[tex]y-y_1=m(x-x_1)[/tex]

Put y₁ = -6, x₁ = 1 and m = -2

[tex]y-(-6)=(-2)(x-1)\\\\y+6=-2x+2\\\\y+2x+6-2=0\\\\y=-2x-4[/tex]

Hence, the equation of line is y=-2x-4.

Write an equation in standard form of the line shown.

Answers

Answer: y= -2x + 4

Hope this helps.

Answer: -2+4x
Explanation: You have to find your slope first in order to put it into standard form. What you have to do to find your slope is y1-y2/x2-x1 so you plug your points into that formula and have 0-2/2-1 which equals -2, so your slope is -2. You now have to put this into standard form, the easy way of doin this is y=mx+b, you have to find b so to do so you have to plug your numbers in from only one pair of points. We’ll use (2,0) so then you’ll have 0=-2(2)+b, we multiply -2*2 and get 4 and you can’t divide 4 into 0 because then you’ll have an undefined line. so your b is 4 which means your equation is -2+4x.

This question concerns bit strings of length six. These bit strings can be divided up into four types depending on their initial and terminal bit. Thus the types are: 0XXXX0, 0XXXX1, 1XXXX0, 1XXXX1. How many bit strings of length six must you select before you are sure to have at least 6 that are of the same type?

Answers

Answer:

We have to choose 21 strings to be sure we have chosen at least 6 strings of the same type.

Step-by-step explanation:

Since the string type is determined by the initial and terminal bits as understood from the question, then the value of the bits between the initial and terminal bits is of no concern to us.

Now, to be sure you have atleast 6 of the same type, we select each string five times. By doing this, we have already selected 20 strings because we have 4 strings there. Now if you choose any of the string one more time, we are certain that we must have chosen atleast 6 strings that are the same. This means we have to choose 21 strings to be sure we have chosen at least 6 strings of the same type.

x>9

Step-by-step explanation:

Remark

You have to watch this question when you divide by a minus. We should try to eliminate that possibility.

Equation

7 - 2/3 x < x - 8             Add 2/3 x to both sides

7 < x + 2/3 x - 8            Combine the like terms on the right.

7 < 1 2/3 x - 8                Add 8 to both sides

7 + 8 < 5/3 x                 Combine the left

15 < 5/3  x                    Multiply both sides by 3/5

15*3/5 < 5/3*3/5 x

9 < x

Since all the answers have the x on the left, we have to put this answer so that x is on the left. Be very careful. The big end of the arrow is towards the x. We have to make sure it stays that way.

Carlos deposited $7,924 into a savings account 30 years ago. The account has an interest rate of 4.6% and the balance is currently $30,541.83. How often does the interest compound?

Answers

Answer:

n = 1, this means the interest compounds ANNUALLY.

Step-by-step explanation:

Carlos deposited $7,924 into a savings account 30 years ago. The account has an interest rate of 4.6% and the balance is currently $30,541.83. How often does the interest compound?

Compound Interest Formula

: A = P(1 + r/n)^nt

A = Amount after time t

P = Principal (Initial Amount Invested)

r = Interest rate

n = Number of times the interest is compounded

t = time in years

A = $30,541.83

r = 4.6% = 0.046

t = 30

P = $7,924

Hence,

$30,541.83 = $7924(1 + 0.046/n)^30n

Divide both sides by 7924

$30,541.93/$7924 = (1 + 0.046/n)^30n

$30,541.93/$7924 = (n + 0.046/n)^30n

3.8543576477 = (n + 0.046/n)^30n

We take the logarithm of both sides

log 3.8543576477 = log (n + 0.046/n)^30n

Solving for n,

n = 1

Therefore, from the calculation above, since n = 1, this means the interest compounds ANNUALLY.
