A large candy bar was 120 calories. Thesmaller candy bar has 16 percent less
calories. How many calories does the
smaller candy bar have?

Answers

Answer 1
Answer: The smaller chocolate bar has 100.8 calories. To find this multiply 120*0.16 to find the “16 percent less” which equals 19.2 less calories. Then subtract 19.2 from 120 to get 100.8

Hope this helps!
Answer 2
Answer: Answer: 119
The candy bar has 119 calories

Answer:

Step-by-step explanation:

The straight, black, dashed line does not resemble the actual (green) line at all, and so it is pointless to compare slopes and y-intercepts here.

However, the pattern of black dots, which represent the measurements obtained through the experiment, do exhibit characteristics comparable to the solid green line.  The green line has been drawn so that it is roughly in the middle of the dot pattern, which in turn indicates that the slope of this pattern is close to that of the green line.  Because this pattern and the green line have similar positive slopes, we can say that the pattern and the line are positively linearly coordinated.  The correlation coefficient is in the range 0.8 - 1.0, which is considered to be a "moderate positive correlation."

What is -5[4-(-3)(2)]

Answers

-5[4 - (-3)(2)]   Given
-5(4 + 6)   Multiply -3 by 2. Since you're subtracting the product, -6, it becomes a positive.
-20 - 30   Distribute
-50   Subtract

Remember that when you're doing a problem that has brackets and parentheses, always do the operations on the inside first. For instance, in this problem, you shouldn't distribute 5 before you multiply -3 by 2.

The solutions of this system:x² + y = -4
y=x²-6
are: (Select)
-5) and ( (Select)

Therefore , the solution of the given problem of equation comes out to be  the system of equations' answers are (-1, -5) and (1, -5).

What is an equation?

The foundation of a regression model based on linearity is the equation y=mx+b. The inclination is B, and the y-intercept is m. Even though y but also y are separate components, the above line is frequently referred as the "mathematical issues with two variables". Two factors make up bivariate linear equations. There are no simple answers for the applications of linear functions. Y=mx+b .

Here,

We can change the second equation into the first equation to find the solution to the system of equations, which results in:

=> x² + (x²-6) = -4

By condensing and rearrangeing, we obtain:

=> 2x² = 2

=> x² = 1

Consequently, x can either be 1 or -1.

We can determine the appropriate values of y by substituting these values of x into either of the two equations:

When x Equals 1:

=> y = x² - 6 = 1 - 6 = -5

When x Equals -1:

=> y = x² - 6 = 1 - 6 = -5

As a result, the system of equations' answers are (-1, -5) and (1, -5).

Help me find the equation for the dimensions of a window, please!

Answers

On the sheet, it's not even asking you for the dimensions.
It's just asking you to set up the equation that you would use
to find the dimensions.  That's a great way to do it, because
nobody actually needs the answers, the whole thing is only
meant to help you learn HOW to find them.
==========================================
Call the width of the window 'W' .

We know that the length is 5 feet more than the width, so the length is (W + 5).

The area is (length times width).

Area = (W + 5) times (W).

36 = (W + 5) W

36 = W² + 5W

Subtract 36 from each side:

W² + 5W - 36 = 0

That's choice-4 .
