what is the answer for 23/4 + -23/4 - -15/4 + 9/4

Answers

Answer:

[tex]-\frac{6}{4}[/tex]

Step-by-step explanation:

The first 2 numbers cancel, and -15/4+9/4 is the same as 9/4 - 15/4

Please mark me as brainliest if I am correct

Answer:

6

Step-by-step explanation:

In the equation, [tex]\frac{23}{4} + -\frac{23}{4} --\frac{15}{4} + \frac{9}{4}[/tex], we can see that [tex]\frac{23}{4} + -\frac{23}{4}[/tex] cancel each other out

This leaves us with [tex]--\frac{15}{4} + \frac{9}{4}[/tex]. The negatives "negate" themselves giving us [tex]\frac{15}{4} + \frac{9}{4} = \frac{24}{4}[/tex] or [tex]6[/tex]

Hopefully (some part of) this explanation makes sense (or at least somewhat). If this doesn't make sense, please tell me and I will try to make it more understandable as soon as possible.

It would help if you marked my answer as Brainliest, if I'm correct, so I can help even more people! (I would really appreciate it!)

How high up on a wall will a 20-foot ladder touch if the foot of the ladder is placed
4 feet from the base of the wall?

Answers

Step-by-step explanation:

by using the pythagoras theorem,

the height of the ladder touching the wall =

√(20²- 4²)

=√ (400-16)

=√384

= 86 feet

or 19.6 feet

Using Pythagorean theorem

[tex]\\ \rm\longmapsto P^2=H^2-B^2[/tex]

[tex]\\ \rm\longmapsto P^2=20^2-4^2[/tex]

[tex]\\ \rm\longmapsto P^2=400-16[/tex]

[tex]\\ \rm\longmapsto P^2=384[/tex]

[tex]\\ \rm\longmapsto P=\sqrt{84}[/tex]

[tex]\\ \rm\longmapsto P=19.6ft[/tex]

you invested 5000 between two accounts paying 3% and 7% annual intrest. If the total intrst earned for the year was $310, how much was invested at each rate?

Answers

Answer:

The total interest of $320 will be the sum of the amount earned in each account.

Step-by-step explanation:

320 = x(0.04)(1) + (5000-x)(0.08)(1)

320 = 0.04x + 400 - 0.08x

-80 = -0.04x

2000 = x

5000 - x = 3000

$2,000 was invested at 4%

$3,000 was invested at 8%

the width of a rectangle is 2w and the length is (w+5) the perimeter is 40 inches what are the measurements of the rectangle​

Answers

Width = 2w , Length = w+5 , perimeter = 40

Perimeter of rectangle = 2 (Length + Width)

P= 2 (L + w)

40 = 2 [ (w+5) + (2w) ]

40 = 2 ( 3w+5)

40= 6w +10

6w= 40 – 10

6w= 30

w = 30/6

w = 5

Width = 2w = 2(5) = 10

Length = w + 5 = 5+5 = 10

There are ‘n’ arithmetic means between 33 and – 3. If second last mean: second mean = 1: 5, find the value of n.

Answers

We know that:

There are n arithmetic means between the numbers 33 and -3

second last mean: second mean = 1:5

Using this, we can find that the value of n is 9.

Now let's see how we need to use the information.

"There are n arithmetic means between the numbers 33 and -3"

This means that we will have a sequence like:

33, a₁, a₂, ..., aₙ, -3

And by the given ratio, we know that:

aₙ₋₂:a₂  = 1:5

Also, because this is an arithmetic sequence we have:

a₁ = 33 + d

a₂ = 33 + d + d

aₙ ₋ ₂ = 33 + (n - 2)*d = -3 - 2*d

Because of the ratio, we will have that:

aₙ₋₂/a₂ = 1/5

We can replace what the left side by:

(-3 - 2*d)/(33 + 2*d) = 1/5

now we can solve this for d.

-3 - 2*d = (33 + 2*d)*(1/5)

5*(-3 - 2*d ) = (33 + 2*d)

-15 - 10d = 33 + 2d

-15 - 33 = 2d + 10d

-48 = 12d

-48/12 = -4 = d

So now we know that the value of d is -4.

Now we can use the equation

aₙ ₋ ₂ = 33 + (n - 2)*d = -3 - 2*d

to find the value of n:

33 + (n - 2)*d = -3 - 2*d

33 + (n - 2)*-4 = -3 - 2*-4

33 - 4n + 8 =  -3 + 8

41 - 4n = 5

-4n = 5 - 41 = -36

n = 36/4 = 9

The value of n is 9.

To find: f(x)-h(x)

f(x)-h(x)= 17x + 9 - 4x

= 13x + 9

Therefore, f(x)-h(x) = 13x + 9.
