what is 283.192 rounded to the nearest hundredth

Answers

Answer:

283.19

Step-by-step explanation:

Find the number in the hundredth place  9  and look one place to the right for the rounding digit  2 . Round up if this number is greater than or equal to  5

and round down if it is less than  5 .

Answer:

283.19

Step-by-step explanation:

So as you should already know, the 2 is the hundreds, 8 is the tenths, and 3 is the ones, but you may not know the ones after it. The number after the little dot (decimal) is a 1 and is called the tenths and the one after is the hundredths and then thousandths and so on. You want to know the hundredths so just keep all of the numbers until you get to the number that is 2 places after the decimal and look at the last number and if its below 5, keep the hundredths the same but if its 5 or over make the hundredths 1 higher. for example 3 stays the same because the next number is below 5. This is how you do rounding with decimals! Please give Brainliest if this helps!

Here is a rectangle ABCD.

20 cm
30 cm
The length of the rectangle is increased by 20%.
The width of the rectangle is increased by 10%.
Find the percentage increase in the area of the rectangle.​

Answers

Answer:

25% increase

Step-by-step explanation:

length is 24 inches after the increase and width is 33 inches (i did length as up and down and width as side to side, that's how I always do it but I might be wrong let me know and I can fix it)

the area before it gets increased it 600

after the increase its 792

and 600 is 75.75% of 792

so it would be 25.25% increase

An absolute value is the positive value of the number between the vertical lines.

If the number in between the vertical lines is negative, the absolute value become a positive.

 If the value in between the lines is already positive, it stays positive.

A salesperson earns $450 per week plus 15% of her weekly sales. The
expression representing her earnings is 450 +0.15x. Which of the following
describes the sales necessary for the salesperson to earn at least $600 in
one week?

Answers

Answer:

If a sales person wants to earn $600 in 1 week they have to make $1000 dollar sale or a bunch of sales that can make $1000

Step-by-step explanation:

Because $600 - $450 gives you $150, and $150 is 15% of her sales to if we were to divide $150 by 0.15 ( 15% in decimal for ) we would get $1000 meaning 15% of 1000 is 150.

I need help I will give BRAINLEST

Answers

Answer:

25%

Step-by-step explanation:

To solve this, we can use the percent change formula shown in the picture attached below. [tex]x_{2}[/tex] is the new value, [tex]x_{1}[/tex] is the old value, and [tex]C[/tex] represents the change. For this problem, 80 is the new value and 64 is the old value. Let's plug those numbers into the formula and solve for the percent change:

[tex]C = \frac{(80-64)}{64} \\[/tex] × [tex]100[/tex]

[tex]C = \frac{16}{64}[/tex] ×[tex]100[/tex]

[tex]C = 0.25[/tex] ×[tex]100[/tex]

[tex]C = 25%[/tex]

Thus, the answer is 25%.

7x-5=4y-6


x intercepts: ( , )

y intercepts: ( , )

Answers

Answer:

x-intercept: -1/7

y-intercept: 1/4

Step-by-step explanation:

change equation into standard form:  7x - 4y = -1

set 'x' to zero and solve for y:  0 - 4y = -1

                                                        y = 1/4

set 'y' to zero and solve for x:  7x - 0 = -1

                                                        x = -1/7

Given that f(x)=2x+1
a) find f(2)
b)find f^-1(x)
c)f^-1(7)

Answers

Answer:

a) [tex]f(2) = 5[/tex], b) [tex]f^{-1} (x) = \frac{x-1}{2}[/tex], c) [tex]f^{-1} (7) = 3[/tex]

Step-by-step explanation:

a) We evaluate the function at [tex]x = 2[/tex]:

[tex]f(2) = 2\cdot (2) + 1[/tex]

[tex]f(2) = 4+1[/tex]

[tex]f(2) = 5[/tex]

b) First, we determine the inverse of the function by algebraic means:

1) [tex]y = 2\cdot x + 1[/tex] Given

2) [tex]y +(-1) = 2\cdot x + [1+(-1)][/tex] Compatibility with addition/Associative property

3) [tex]y + (-1) =2\cdot x[/tex] Existence of additive inverse/Modulative property

4) [tex]2^{-1}\cdot [y+(-1)] = (2\cdot 2^{-1})\cdot x[/tex] Compatibility with multiplication/Commutative and associative properties

5) [tex][y+(-1)]\cdot 2^{-1} = x[/tex] Existence of multiplicative inverse/Modulative and commutative properties

6) [tex]x = [y+(-1)]\cdot 2^{-1}[/tex] Symmetry property of equality

7) [tex]x = \frac{y-1}{2}[/tex] Definitions of subtraction and division

8) [tex]f^{-1} (x) = \frac{x-1}{2}[/tex] [tex]x = f_{-1} (x)[/tex]/[tex]y = x[/tex]/Result

c)  Now we evaluate the expression obtained on b) at the given number:

[tex]f^{-1} (7) = \frac{7-1}{2}[/tex]

[tex]f^{-1} (7) = 3[/tex]

Answers

Answer:

3 cm

Step-by-step explanation:

Answer:

2.5cm

Step-by-step explanation:

The shapes are similar and so have a scale-factor. We can find the scale-factor by dividing one of the lengths that we know on the bigger shape by the corresponding side on the smaller shape.

For example: PQ/LM = 6/3 = 2

Now that we know to get from the larger shape to the smaller shape, we have to multiply by 2. We can use this scale factor to find the length of the side MN.

QR = MN x 2

MN = QR/2 = 5/2 = 2.5cm

Rewrite the equation 6x – 9y = 12 in terms of y.

Answers

Answer:

Step-by-step explanation:

6x - 9y = 12

subtract 6x from both sides

-9y = 12 - 6x

divide both sides by -9

y = -4/3 + 2/3x

or

y = 2/3x - 4/3

The equation 6x – 9y = 12 written in terms of y is; y = (2/3)x - 4/3

We are required to write the equation 6x – 9y = 12 in terms of y.

Rewriting the equation 6x – 9y = 12 in terms of y is as follows;

6x – 9y = 12

6x - 12 = 9y

Divide through by 9 so that we have;

y = (2/3)x - 4/3
