Can someone help me out my grades are bad

Answer:

No, I got 18

Step-by-step explanation:

180-78=102

180-11-49=120

180-120=60

x=180-102-60=18

Answer:

100 - 1/20 = 99.95

99.95 - 45 = 54.95

54.95  x 18/100 = 9.891, 54.95 - 9.891 = 45.059

45.059 - 12 = 33.059

33.059 divided by 2.50 = 13.2236, about 13 games

Answer:

$15,334.37

Step-by-step explanation:

Lancelot deposited $5000 each into 2 different savings accounts.

Step 1- For simple Interest

Amount of money in the account

Account A earns 8% simple interest.

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year.

Solving our equation:

A = 5000(1 + (0.08 × 6)) = 7400

A = $7,400.00

Step 2- For Compounded Interest

Account B earns 8% interest compounded annually.

First, convert R as a percent to r as a decimal

r = R/100

r = 8/100

r = 0.08 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 5,000.00(1 + 0.08/1)(1)(6)

A = 5,000.00(1 + 0.08)(6)

A = $7,934.37

The sum of the balances of both accounts at the end of 6 years is calculated as:

$7,934.37 + $7,400.00

=$15,334.37

Answer:

13 x 7

Step-by-step explanation:

area = L x W

91 = (x - 1)(x + 5)

x² + 5x - x - 5 = 91

combine like terms:

x² + 4x - 5 = 91

subtract 91 to each side of the equation:

x² + 4x - 96 = 0

factor:

(x + 12)(x - 8)

x = 8

x - 1 = 7

x + 5 = 13

Answer:

When we have a rectangular point (x, y), the angle between the x-axis and a ray that connects the origin with this point is given by:

Tan(θ) = y/x.

Cos(θ) = x/(√(x^2 + y^2))

Sin(θ) = y/(√(x^2 + y^2))

So for the point (-4,3) we have:

x = -4

y = 3

√( (-4)^2 + 3^2) = √(16 + 9) = √25 = 5

Then:

Tan(θ) = 3/-4 = -(3/4)

Sin(θ) = 3/5

Cos(θ) = -4/5

And for the other 3 trigonometric functions (the inverses of the 3 above ones) we have:

Ctg(θ) = 1/Tan(θ) = -4/3

Csc(θ) = 1/Sin(θ) = 5/3

Sec(θ) = 1/Cos(θ) = -4/5

i got it right cus im smart

==================================================

Explanation:

Any binomial distribution has two unique components to it: The number of trials n, and the probability of success p.

We're given n = 12, and we need to find p.

The variance of a binomial probability distribution is given by the formula n*p*(1-p). Plug in n = 12 and set this equal to 1.92

So the equation to solve is 12p*(1-p) = 1.92

Solve for p using a graphing calculator or you could apply the quadratic formula. Either way, you should get the two results of p = 0.2 and p = 0.8

Note that if p = 0.2, then 1-p = 1-0.2 = 0.8, and things flip around when p = 0.8.

Answer:

B. 5 2/5

Step-by-step explanation:

Use the long division solution to convert the original fraction  ( 27/ 5 )  to a mixed number. The whole number portion of the mixed number will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction ( 5 ) , and the fraction portion of the mixed number will be the remainder of the original fraction division  ( 2 )  over the denominator of the original fraction  ( 5 )

Answer:

No.

Step-by-step explanation:

For the inequality 7 ≥ r, 9 is not a solution. This inequality states that seven is greater than or equal to r, but 7 is not greater than or equal to 9. So this makes 9 not a solution for this inequality.

Answer:

B. 7.94  × 10^8 miles

Step-by-step explanation:

Given that

Earth is approximately 9.3 × 107 miles from the sun.

Saturn is approximately 8.87 × 108 miles from the sun.

We need to find out how much farther is saturn from the sun than earth is

So,

Earth - Sun = 9.3 × 10^7 miles

Saturn - Sun = 8.87 × 10^8 miles

Now  

= 8.87  × 10^8 - 9.3  × 10^7

= 88.7  × 10^7 - 9.3  × 10^7  

= 79.4  × 10^7

= 7.94  × 10 ^8

= 794,000,000 miles

Hence, saturn is  7.94  × 10^8 miles farther from Sun than Earth is

Answer:

the surface of hexagonal prism is 12 cm

Answer:

Step-by-step explanation:

                   x

(f/g)(x) = -----------

                x + 1

Notice that x cannot be -1, which would lead to division by zero.  Thus, x = -1 is the vertical asymptote.  Also notice that if x grows increasingly large, the fraction shown tends towards x/x, or 1, so we know that the horizontal asymptote is y = 1.

Draw a set of x-y axes and graph y = 1 and x = -1.  Plot (0, 0).  Again, note that the graph of this function never touches/crosses x = -1.  So, for (-1, 0) the graph is a curve caught between x = -1 and x = 0 that increases as x increases.  For (0, infinity), the graph heads upward at a slow pace and then levels off nearly parallel to y = 1 (the horizontal asymptote).

As x increases from left to right, y starts out slightly greater than y = 1 and then (while still in Quadrant II) curves upward and approaches the vertical asymptote x = -1.
