Hello im in 11th grade, im currently struggling in two classes: chemistry and spanish. Im already in the second semester, and ju

st realized how lightly ive been taking school. For chemistry, in my first quarter i scored a 60% F, in my second quarter is scored a 68% D, and my semester grade resulted to be a score of a 64% F. I started my second semester and in the third quarter i got a 68% D, and was wondering what my fourth quarter grade would have to be in order to at least have a 70% in the class. When it comes to spanish,in the first quarter i scored a 72% C+, in the second quarter i got a 57% F, and my first semester grade resulted to be a 65% F, in my third quarter i received a 68% D, and was also wondering what my fourth quarter grade would have to be to at least meet the requirement of a 70% C-? (if you are wondering why im bothering to average my first semester grades when i had already failed and would normally already had to retake the class, it is because my school was lenient enough to allow me to raise my grades up during 2nd semester, and average out my 1st and 2nd semester grades. They said if i at least scored a 70% average onces that had average both semesters they wouldn't have me repeat the classes over again)

The Caesar Cipher of the sentence "THIS MESSAGE IS TOP SECRET."
vagabundo [1.1K]

Answer:  Option 'a' is correct.

Step-by-step explanation:

Since we have given that

"THIS MESSAGE IS TOP SECRET."

We need to use the Caesar cipher.

As in general we always take a shift of 3 keys in Caesar cipher.

so, According to shift of 3 keys it becomes,

T→W

H→K

I→L

S→V

M→P

E→H

A→D

G→J

O→R

C→F

R→U

P→S

So, it can be written as

"THIS MESSAGE IS TOP SECRET."

WKLVP HVVDJ HLVWR SVHFU  HW.

we make a set of 5 letters in a word after Caesar cypher.

Hence, Option 'a' is correct.

(Which is the simplified form of the expression ? 3(7/5x+4)-2(3/2-5/4x)
Illusion [34]

Answer:

let's see what to do buddy....

Step-by-step explanation:

3( \frac{7}{5}x + 4) - 2( \frac{3}{2} -  \frac{5}{4}x) \\  \\  =  \frac{21}{5}x + 12  - 3 +  \frac{5}{2}x \\  \\  =  \frac{(21 \times 2) + (5 \times 5)}{10}  x + 9 =  \\  \\  \frac{42 + 25}{10} x + 9 =  \frac{67}{10}x + 9 = 6.7x + 9

What is the amount, base, and percent in the expression.
Illusion [34]

Answer:

The correct answer is :

Amount: 2

Base: 100

Percent: 2%

Step-by-step explanation:

So, we get the answer by using whatever we know. The first step is that 2 is the percent because it is having the percent sign . In addition we know that 100 is the base. And the one which is left is 2 so it's the amount.

Some one plz help meh I need to understand and I dont
vfiekz [6]

Answer:

It's asking you to find the inputs of the function.

Step-by-step explanation:

Basically, when you input something, you replace "x" in the equation with the number you want to input. For example, if I had the equation: 5x/6+5, then I wanted to input "5", then 5 would replace x in the equation, making 5(5)/6+5. The output they are giving you is simply evaluating the equation that you used to input x, so basically in the case I gave you, the output would be 5(5)/6+5, or 25/6+5, and 55/6. Using the outputs, they want you to find the inputs.

Slope=-3 goes through (1,2) whats the equation
dedylja [7]

Hi student, let me help you out! :)

..............................................................................................................................................

We are asked to find the equation of the line, using the given information:

\star~\mathrm{-3}, which is the slope

\star~\mathrm{(1,2)} which is a point that the line contains

\triangle~\fbox{\bf{KEY:}}

  • The slope is the number before x, in the form \mathtt{y=mx+b}.

Since "m" is the slope, and we're given what the slope is, we can substitute -3 for m:

\dag~\mathtt{y=-3x+b}

|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Now, we need to find the y intercept, "b", of the line.

Here's how it's done:

Remember the point that the line contains, (1,2)?

Well, its y-coordinate is 2; so what we do is substitute 2 for y:

\dag~\mathtt{2=-3x+b}

Also, its x-coordinate is 1, so we substitute 1 for x:

\dag~\mathtt{2=-3(1)+b}

Now, solve for b:

\dag~\mathtt{2=-3+b}

Add 3 to both sides:

\dag~\mathtt{2+3=b}

Thus, we have

\dag~\mathtt{5=b}

Thus, the equation of the line is:

\bigstar\underline{\boxed{\mathtt{y=-3x+5}}}

Hope it helps you out! :D

Ask in comments if any queries arise.
