Answer:

$9.75

Step-by-step explanation:

65% of 15 is 9.75

Hope this helps∞<3

Let me know if it right or wrong.

Answer:

$9.75

Step-by-step explanation:

To find the sale price, you multiply the sale percent by the original price.  For this problem, it would be 0.65 * 15, which equals $9.75.

(If you didn't already know, you get the decimal version of a percent by moving the decimal at the end two places to the left.)

Answer:

A. [tex]y =\frac{7}{8}x+1[/tex]

B. [tex]y = -10x[/tex]

C. [tex]y = 2.5x - 7[/tex]

D. [tex]y = 1.2x[/tex]

E. [tex]y = -5x -8[/tex]

Step-by-step explanation:

Let the descriptions be A to E.

First, we need to note the followings.

An equation is of the form

[tex]y = mx + b[/tex]

[tex]m = slope[/tex] and [tex]b = y\ intercept[/tex]

A. Non proportional graph with positive y intercept

From the list of options, only

The slope of [tex]y =\frac{7}{8}x+1[/tex] is positive

and y intercept is also positive

B. Negative slope and pass through the origin.

Negative slope means m is negative

From the list of options

[tex]y = -10x[/tex] and [tex]y = -5x -8[/tex]

Origin implies (0,0)

i.e: [tex]x = 0[/tex] and [tex]y = 0[/tex]

For y = -10x

[tex]0 = -10 * 0[/tex]

[tex]0 = 0[/tex] --- This is true

For [tex]y = -5x -8[/tex]

[tex]0 = -5 * 0 - 8[/tex]

[tex]0 = 0 - 8[/tex]

[tex]0 = -8[/tex] --- This is not true

Hence:

[tex]y = -10x[/tex] fits this description

C. Increases from left to right and b is negative

For b is negative, we have the following:

[tex]y = -5x -8[/tex] and

[tex]y = 2.5x - 7[/tex]

An increment from left to right, means the slope is positive.

So, we have:

[tex]y = 2.5x - 7[/tex]

D. Positive slope and contains (0,0)

From the options, we have the following functions left:

[tex]y = -5x -8[/tex] and

[tex]y = 1.2x[/tex]

But [tex]y = 1.2x[/tex] has a positive slope and also contain (0,0) because

[tex]0 = 1.2 * 0[/tex]

[tex]0 = 0[/tex]

E. Negative m and Negative b

[tex]y = -5x -8[/tex] has these descriptions

Answer:

the height of bag b is 7

Step-by-step explanation:

first, find the volume of bag a.

volume formula:

length * width * height = volume

length = 4

width = 3.5

height = 6

substitute the values into the formula

4 * 3.5 * 6 = volume

84 = volume

the volume of bag A is 84

next, find the height of bag b

volume formula:

length * width * height.

length = 8

width = 3

volume = 168 (84 * 2)

8 * 3 * h = 168

24h = 168

24h/24 = 168/24

h = 168/24

h = 7

the height of bag B is 7

mabe try $24.10

Step-by-step explanation:

Answer:

X = 24

Step-by-step explanation:

Just apply H² = B² + P²

(26)² = (10)² + P²

676 = 100 = P²

676 - 100 = P²

P² = 576

P = √576

P = 24

P = X

Answer: Choice B) 7/2 and choice D) 2

These two slope values are positive. Positive slopes correspond to lines that move uphill as you move from left to right.

A negative slope moves in the opposite direction. A slope of zero refers to a flat horizontal line. A slope of undefined means we have a vertical line.

the simplest fraction is: 3/5

in decimal form its: 0.6

Step-by-step explanation:

The sequence is an AP with common difference -7.

Therefore the next 2 terms are 1 and -6.

The next two terms are ( 1, - 6 ) so the correct answer is option D.

The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.

The next two numbers will be calculated as:-

22, 15, 8, __, __

Common difference = 15 - 22 = -7

Add this common difference in 8 to find the next term.

Next term = 8 - 7 = 1

Again add -7 to 1 to find the next term.

Next term = 1 - 7 = -6

Therefore the next two terms are ( 1, - 6 ) so the correct answer is option D.

Answer:

(x+2)(x+3)

Explanation:

(x+2)(x+3)

If you simplify this, you get:

x*x = x^2

x*3 = 3x

2*x = 2x

2*3 = 6

If we add these all together we will have:

x^2 + 3x + 3x + 6

Combine like terms
