If I have 44 lessons to do and I have done 36 what percentage of the lessons do I have done/ have left?

Answer:5,600 - 3,500 = 2,100

2,100 is what percent of 3,500?

2,100 = X*3,500

X =  2,100 / 3,500

X = .60 or 60%

An average of 15% increase per year.

Answer:

The triangle is not acute because 2^2 + 4^2 < 5^2

Step-by-step explanation:

2^2 is side a,

4^2 is side b,

5^2 is side c,

then

c^2 = a^2 + b^2 is right triangle

c^2 > a^2 + b^2 is obtuse

c^2 < a^2 + b^2 is acute

If we insert the numbers into the equation and square them:

c^2 = a^2 + b^2

25 = 4 + 16

25 > 20

This means the triangle is NOT accute, but obtuse

Therefore, it means the triangle is not acute, but obtuse

i.e.,

[tex]a^2 > b^2+c^2\\\\5^2 > 2^2+4^2[/tex]

What is the acute angle?

An angle is formed when two rays meet at a vertex. When this angle measures less than [tex]90[/tex] degree, it is termed an acute angle.

As per the Pythagoras theorem the triangle is acute only if the square of the longest side is less than the sum of the squares of the two smaller sides.

i.e., [tex]a^2 < b^2+c^2[/tex]

where [tex]a,b,c[/tex] are the lengths of the sides of a triangle.

So,

[tex]a^2=5^2\\b^2=2^2\\c^2=4^2[/tex]

Then,

The right triangle is [tex]a^2=b^2+c^2[/tex].

The obtuse triangle is [tex]a^2 > b^2+c^2[/tex]

The acute triangle is [tex]a^2 < b^2 + c^2[/tex]

i.e.,

[tex]5^2 = 2^2+4^2\\\\25=4+16\\\\25 > 20[/tex]

Hence, this means the triangle is not acute, but obtuse.

1# Answer:

4x=-12

Step-by-step explanation:

Let a number = X

So

The product of four and a number is negative twelve

4x=-12

2#

3 - 6x = -15 is the equation (it says 3 decreased by the product not the product decreased by 3)

The equation is given by:

 9-1/3x = 7      

Step-by-step explanation:

Let the number be denoted by x.

Now, we are given a word phrase as follows:

One-third of a number less than nine is equal to seven.

Now this word phrase could be mathematically expressed as a equation by:

 one-third of x is: 1/3 x

and this number less than 9 is given by:

 9-1/3x

Now, this number is equal to 7.

i.e. we finally have:

 9-1/3x = 7

Answer: 8x-20 [1]  x-5y[2]  7xy+2x^[ exponet2] t

Step-by-step explanation:

Answer:

Part A:

The Standard Form equation of a line has the following formula:

Ax+By=C, where A, B, and C are integers, and A is non-negative.

We will assume that when renting a boat Sam paid fixed cost and rental charge per day.

y = the total rent

x = the number of days

Sam rented a boat at $225 for 2 days would mean:

y = 225 when x = 2 or if we plug into Ax+By=C:

2A + 225B = C since A is non-negative we divide both sides by A

2 + (B/A)225 = C/A

He rents the same boat for 5 days, he has to pay a total rent of $480 means:

y = 480 when x = 5 days

5A + 480B = C since A is non-negative we divide both sides by A

5 + (B/A)480 = C/A

Now we have:

2 + (B/A)225 = C/A

5 + (B/A)480 = C/A

Lets denote s = B/A  and t = C/A. Now we can write the following system of equations:

2 + 225s = t

5 + 480s = t

........

........

s = -1/85

t = -11/17 = -55/85

Now we can go back to:

B/A = -1/85 and C/A = -55/85

A = 85, B = -1, C = -55

The standard equation is:

85x - y = -55

Part B:

Using the equation 85x - y = -55 we solve for y

.......

y = 85x + 55

Answer:

87.75 or 88

Step-by-step explanation:

To find the average you add the variables together

80+90+85+96=351

And then you take that number and divide by how many variables there are

351÷4=87.75 and you can round up to 88 if you want.

Step-by-step explanation:

A is correct because if the minimum is 29,000 feet, x (the airplane altitutude) must be greater than or equal to 29,000 ft. Since the maximum is 41,000 feet, x must be less than or equal to that number.

Answer:

60

Step-by-step explanation:

horizontal plane = 180

therefore 180 - b + 27 = 180

this will give us the missing inner angle

then we create a linear equation to get the value of b, and since the sum of the inner angles of the triangle = 180

b - 7 + b - 26 + (180 - 27 - b) = 180

b = 60

Answer:

About $16.42

Step-by-step explanation:

Since you know the overall price of 5 cans of pinto beans is 3.35, you divide 5 by 3.35, to get the price of one can.

5 / 3.35 = 1.49, giving you the price of one can of pinto beans

You then multiply this number by 11, which gives you 16.42 (rounded)

(18x-44) + (8x-10) = 180

26x-54 = 180

26x = 234

x = 9

8(9)-10 + (13y-38) = 180

72-10+13y-38 = 180

13y+24 = 180

13y=156

Answer:

The ___a_ value of the quadratic function determines whether the parabola opens upward or downward.

Answer:

The 'a' value.

Step-by-step explanation:

The general quadradic equation is:

[tex]ax^2 + bx + c; \text{ } a\neq 0[/tex]

If the value of a is greater than 0, then the parabola would open upward. If the value of a is less than 0, then the parabola would open downward.

Answer:

In two years, George will be 8 years old.

Step-by-step explanation:

g = 3s

(g + 2) / 2 = a + 2

g + 2 = 2 (s + 2)

g + 2 = 2s + 4

g = 2s + 2

3s = 2s + 2

s = 2

g = 3s

g = 3 (2)

g = 6

6 + 2 = 8
