in the decimals chart, the memory cue for dividing by a whole number is "up." what does that mean?

Answers

Answer 1

Rounding up is a rule that is used, no matter what the value is. We round numbers up to get a better estimate for our answers. The memory cue for dividing by a whole number "up" just means that you will be bringing the decimal up.

Answer 2

Answer:

It means that you have to put the decimal point in the quotient exactly above the decimal point in the dividend.

Step-by-step explanation:

In the picture attached, the decimals chart is shown. There you can see where you have to put the decimal point in the quotient when you are dividing a decimal number by a whole number.

1. That is a right triangle, what means that it has a angle of 90°, so you can calculate the value of "x" "as below:

Tan(α)=Opposite leg/Adjacent leg

The angle α is 60°, so the opposite leg is "x" and the adjacent leg is 5.

2. When you substitue these values, you have:

Tan(α)=Opposite leg/Adjacent leg
Tan(60°)=x/5
x=(5)(Tan(60°)
x=5√3

Then, the answer is: The value of "x" is 5√3

This is an ADDMATHS QUESTION so I'm not sure if anyone can help me but please try to ㅠ ㅠ: Find the equation of the normal to the curve y=ln(2x^2 - 7) at the point where the curve crosses the positive x-axis. Give your answer in the form ax+by+c=0 , where a, b and c are integers.

Answers

You can go through the effort of determining the zero of the function analytically and evaluating an analytic expression for the derivative at that point, or you can let a graphing calculator do that heavy lifting. Since the numbers have to be "nice" for your equation to have the desired form, it is easy to know what to round to in the event that is necessary (it isn't).

We find the positive zero-crossing at x=2, and the slope of the curve at that point to be 8. Thus the line will have slope -1/8 and can be written as
.. x +8y -2 = 0

This equation crosses the positive x-axis at (0, 2). I used a graphing calculator, you could brute force it if you'd like.

First, take the derivative of the equation given:
[tex]y = ln(2x^2-7)[/tex]
[tex]y' = \frac{4x}{2x^2-7} [/tex]

At 2, the function has a derivative of 8 (just plug in 2 to y'). So, the perpendicular to that has to have the slope -1/8 because of the negative-inverse rule. We have this until now:
[tex]y = -\frac{1}{8}x -2[/tex]

Now, we have to get a 0 on the right side, so, just get everything on the other side, and you are done.

Answers

Answer:

Option C - [tex]|5-(-4)|[/tex]

Step-by-step explanation:

To find : Which of the following expressions represents the distances between -4 and 5 on the number line?

Solution :

According to number line,

<-----------|----|------|----|-----|----|---|----|----|----|-----|----|---------------->

-∞ -5 -4 -3 -2 -1 0 1 2 3 4 5 6 +∞

The distance between -4 and 5 is given by,

[tex]d=|5-(-4)|[/tex]

Solving the expression,

[tex]d=|5+4|[/tex]

[tex]d=|9|[/tex]

[tex]d=9[/tex]

Therefore, The expression represents the distances between -4 and 5 on the number line is [tex]d=|5-(-4)|[/tex]

So, Option C is correct.

Answer:

D is the answer

Step-by-step explanation:

|-4-5|=|-9|=9

the distance between -4 and 0 is 4 .....and between 0 and 5 is 5

so the distance will be 4+5=9

Theo bought two hot dogs and two sodas for $4.00. At the same concession stand, Vicky bought three hot dogs and a soda for $4.50. What is the price of a hot dog at the concession stand?

Answers

Hotdog @ 0.50 cents
Soda @ $3.00

If Theo bought two hot dogs and two sodas for $4.00. At the same concession stand, Vicky bought three hot dogs and a soda for $4.50. Then $1.125 is the price of a hot dog at the concession stand

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Theo bought two hot dogs and two sodas for $4.00.

Let hot dogs denoted by H

Soda denoted by S

2H+2S=4...(1)

Vicky bought three hot dogs and a soda for $4.50

3H+S=4.50..(2)

Multiply (2) with 2

6H+2S=9..(3)

Now subtract 3 from 1

2H+2S-6H-2S=4.50-9

-4H=-4.5

H=1.125

Now plug in H value in 2

3(1.125)+S=4.5

3.375+S=4.5

S=4.5-3.375

S=1.125

Hence $1.125 is the price of a hot dog at the concession stand

There were n signers of the Declaration of Independence. The youngest was Edward Rutledge, who was x years old. The oldest was Benjamin Franklin, who was y years old. X is 25% of 104, 7 is 10% of y, and n is 80% of y. Y is what percent of (n+y-x)?

Answers

X = .25 x 104 X=26
Y= 7/.10 Y=70
N= .8 x 70 N=56
n+y-x 56+70-26=100

70/100 = .7 or 70%
The answer is: Y is 70% of (n+y-x)

Answer:

70%

Step-by-step explanation:

First we calculate X using the following formula:

X = 25/100 * 104

X = 0.25 * 104

X = 26

Then we calculate Y using the following formula:

7 = 10/100 * Y

7 = 0.1 * Y

7/0.1 = Y

Y = 70

Then we calculate N as per the formula below:

N = 80/100 * Y

N = 0.8 * 70

N = 56

Finally using the formula mentioned in question we derive Y what percent of N + Y - X:

= Y/ (N + Y - X) * 100

= 70/ (56 + 70 - 26) * 100

= 70/100 * 100

= 70%

Rick discounts a 100-day note for $25,000 at 13%. The effective rate of interest to the nearest hundredth percent is

A. 13.48%.
B. 13.03%.
C. 13.02%.
D. 13.49%.

Answers

First we have to calculate the amount of interest. This can be done by using the interest formula, I = P x R x T.

= 25,000 x 0.13 x (100/365)
= 902.78

This will be deducted from the principal amount, which is 25,000.

= 24,097

Last, we plug our values in to the effective rate formula for interest:

[tex] \frac{Interest}{Proceeds x Time of Note} [/tex]

902.78/6693.6722

= 13.487066

After rounding, we come to our final answer, which is D, 13.49%.

The surface area of a square pyramid is 136 square inches. The base length is 4 inches. What is the slant height?

Answers

15 inches.

The side length of the base is 4. Find the surface area of the base only by squaring the side length - 4² - which is 16. The surface area of the base is 16 in².

The surface area of the entire pyramid can be found using this equation:

[tex]SA = B + \frac{1}{2} nbl[/tex]

Where:
- SA is the surface area (136 square inches)
- B is the area of the base (16 square inches)
- n is the number of triangles (4, because it's a square pyramid)
- b is the base length (4 inches)
- l is the slant length

Note that we have many parts of this equation, and all we need is the slant length. So, let's format the equation with what we have:

[tex]136 = 16 + \frac{1}{2} * 4 * 4 * l[/tex]

So then we want to solve for l, the slant height. So, start by subtracting 16 from each side. This would give us:

[tex]120 = \frac{1}{2} * 4 * 4 * l[/tex]

Now, multiply both sides by 2 to get rid of the fraction:

[tex]240 = 4 * 4 * l[/tex]

Finally, divide both sides by four, twice (divide by 16):

[tex]15 = l[/tex]

So, we know that the slant height of this pyramid is 15 inches.
