please help with my geometry & a step by step

Answer:

40%

Step-by-step explanation:

We would use an example

assume the price of the radio is 100

After the initial price reduction, it would be worth (100 - 20%) 80% of the price

0.8 x 100 = 80

After second price reduction it would be worth (100 - 25% ) 75% of the price

0.75 x 80 = 60

Price change = (new price after all the discounts / original price) - 1

(60/100) - 1 = -0.4

Step-by-step explanation:

You simply jusr divide the area with the lenght given

Answer:

u=17kilometres

Step-by-step explanation:

area of parllelogram =base×height

289km²=17×u

u=289/17=17km

Answer:

Chad is incorrect

Step-by-step explanation:

Since A is in quadrant 2, we know the x must be negative and y is positive. Therefore, if we add a negative sign in front of both x and y, x will become positive, and y will become negative. However, in the 3rd quadrant, both x and y must be negative, which is not the case here. Hence, Chad is wrong.

Answer

0.266

Step-by-step explanation:

x  ~ N(2,0.[tex]8^{2}[/tex])

P(x>2.5)

=P(Z>[tex]\frac{2.5-2}{0.8}[/tex])

=p(z >0.625)

=1-   Φ(0.625)

= 1 - 0.734

=0.266

Answer:

His sister is 10?

Step-by-step explanation:

Because if he's 16 then she's 10

Answer:

Correct

Step-by-step explanation:

To isolate the variable of x, simply add 16 to 11 which is 27 and now it is set up as 4.5x=27 and 27/4.5, it = 6

Answer:

Gray and all are right.

Step-by-step explanation:

4.5x + 16 = 11.5

4.5x = 11.5 - 16

4.5x = -4,5

x = -4.5/4.5

x = -1

4.5x + 27 = -9

4.5x = -9 - 27

4.5x = -36

x = -36/4.5

x = -8

4.5x - 16 = 11

4.5x = 11 + 16

4.5x = 27

x = 27/4.5

x = 6

-4.5x + 27 = 45

-4.5x = 45 - 27

-4.5x = 18

x = 18/-4.5

x = -4

Answer is 45 :) Have a nice day!

I think its 45 for a shorter way you can just put

5×5+15÷5×6 in the calculator because 5 to the second power is just the number times it self

Answer:

where's the question. you gave no information....

Step-by-step explanation:

I don't know what I have to work with...

Step-by-step explanation:

5x-2y=10

x-y=-1

Addition method

multiply the second equation by -2 and add it to the first one

5x-2y=10

-2x+2y=2

Total 3x=12

Divide by sides by 3

x=4

Now multiply the second equation by -5 and add it to the first one

5x-2y=10

-5x+5y=5

3y=15

Divide both sides by 3

y=5

Solutions are x=4 and y=5

2nd method

if x-y=-1, so x=y-1

bring the value of x in the first equation

5(y-1)-2y=10

5y-5-2y=10

put the similar term together

3y=15

Divide both sides by 3

y=5

now bring the value of y in one of the equation

x-y=-1

so x-(5)=-1

x=-1+5

x=4

Solutions are x=4; y=5

Answer: 4)y=3x-1

Step-by-step explanation:

The y value relates to the dilatation center, which the line image's equation will be [tex]y = 3x - 1[/tex]. In standard form, [tex]y = mx + b[/tex] y-intercept is represented by the letter b.

[tex]y = 3x - 1[/tex] is the equation of a line.

If somehow the line is dilatable by a factor of 2 and centered at [tex](3, 8)[/tex]. To begin with, we must determine the y-value for which [tex]x = 3[/tex].

[tex]y = 3(3) - 1\\\\y = 9 - 1\\\\y = 8[/tex]

This equation of the line image will be [tex]y = 3x - 1[/tex], because the y value is comparable to the center of dilatation.

Answer:

3/4

Step-by-step explanation:

The greatest common factor is 2 since 2 divides both into 6 and 8 so 3/4 is the answer since 3x2/4x2

Answer:

The maximum number of bottles in each box is equal to 9.

Step-by-step explanation:

Garth bought 18 bottles, Rico bought 36 bottles, and Mai bought 45 bottles. We need to find the maximum number of bottles in each box. It can be calculated using HCF of 18, 36 and 45

The factors of 18 are: 1, 2, 3, 6, 9, 18

The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36

The factors of 45 are: 1, 3, 5, 9, 15, 45

Then the greatest common factor is 9.

So, there are 9 bottles in each box.

15% as a decimal is 0.15

Multiply the amount of the bill by the percentage:

54.83 x 0.15 = 8.22

The tip was $8.22

Answer:

[tex]\huge\boxed{ \$ \ 8.22}[/tex]

Step-by-step explanation:

Bill = $54.83

Tip = 15 % of 54.83

[% means out of 100, "of" means to "multiply"]

Tip:

= 15% of 54.83

= 15 / 100 * 54.83

= 0.15 * 54.83

= $ 8.22
