Chinedu sat down to do his homework, which included 30 math problems. He solved 2 problems each minute. Let f(n) be the number o

vova2212 [387]

Answer:

It would be an arithmetic sequence.

Step-by-step explanation:

This is because during each minute, he does another 2 problems. Or, in other words +2 each minute.

This is the result of the sequence during each minute:

(Problems Left): <em>30, 28, 26, 24, 22... 0</em>

Time (Minutes) --->

If it was instead a geometric equation, it would go by a multiple, such as the number 2. Or, ×2 each minute.

During the first minute, he learns 2 problems. But then as each minutes passes it turns into 4, then 8, and etc..

This is the result of the pretend sequence during each minute: (Problems Left): <em>30, 28, 24, 16, 0</em>

Time (Minutes) --->

The formula would be for this equation would follow

an = a1 + (n-1)d

an is your result.

a1 is the first number you plug in

(n-1) is just there, don't mind it (aka: the term position).

and d is the rate.

So just plug them in from your equation, and you would get this:

an = 30(n-1)2

Please help me find x<br> Need help fast!!

Bond [772]

Answer:

x = 100°

Step-by-step explanation:

p and q are parallel lines. Construct line 'l' parallel to p and q

a = 30° {p// l when parallel lines are intersected by transversal alternate interior angles are congruent}

c +110 = 180 {linear pair}

c = 180 - 110

c = 70°

b= c {q // l when parallel lines are intersected by transversal alternate interior angles are congruent}

b = 70°

x = a + b

x = 30° + 70°

x = 100°

<h3>Answer:</h3>

$\large\boxed{-1\frac{16}{25},\,\frac{6}{40},\,0.35,\,1\frac{3}{4}}$

<h3>Step-by-step explanation:</h3>

In this question, it's asking you to put the numbers that were given from <em>least </em>to <em>greatest.</em>

Our given numbers are:

$\frac{6}{40}$
0.35
$1\frac{3}{4}$
$-1\frac{16}{25}$

Now, lets sort them out.

We know that negative numbers would be the least. Sicne there's only one negative number, we would put that first because it's the least out of the numbers.

$\frac{6}{40}$ would go next. To make it easier, we can turn it into a decimal. $\frac{6}{40} = 0.15$ when you divide.

0.35 will go next. This would be bigger than 0.15, but lower than the next number.

$1\frac{3}{4}$ would go last, due to the fact that it's the greatest. $1\frac{3}{4}$ is the same as 1.75

When you put them in order, you should get $-1\frac{16}{25},\,\frac{6}{40},\,0.35,\,1\frac{3}{4}$
