!!HELPPP ME AND MY FRIENDD!!​

Step-by-step explanation:

To find the percent increase, divide the increase by the original price.

P1 = price yesterday

P2 = price today

To find percent increase

[tex] \frac{(p2 - p1)}{p1} [/tex]

Or to answer the question,

P1 = 9.74

P2 = 9.87

[tex] \frac{(9.87 - 9.74)}{9.74} = 0.013347[/tex]

Step-by-step explanation:

Lateral Area of Pyramid:

L = 1/2Pl

l = 15.9

P = 2(8.2) + 2(8.2) = 32.8

L = 1/2(32.8)(15.9) = 260.76

Surface Area:

SA = B + L

B = (8.2)(8.2) = 67.24

L = 1/2(32.8)(15.9) = 260.76

SA = 67.24 + 260.76 = 328

Answer:

  (x, y) = (3, 12)

Step-by-step explanation:

Using the given variable definitions, we can write the equations ...

  y = x + 9

  2(x +y) = 30

__

Solving the second equation for y, we have ...

  y = 15 -x

Substituting this into the first equation gives ...

  15 -x = x +9

  6 = 2x . . . . . . . . . add x-9

  3 = x . . . . . . . . . . divide by 2

  y = 3+9 = 12 . . . . substitute into the first equation

The numbers are (x, y) = (3, 12).

Answer:

c 0.561

Step-by-step explanation:

did the test on edge

The probability that more than 30% of the owners in the sample pay for someone to walk their dog is option c. 0.561.

Since 31% of dog owners pay for someone to walk their dogs. Morgan asks a random sample of 50 dog

So

= P> ( 0.30 - 0.31) / √0.31 (1 - 0.31)/ 50

= P(z > - 0.1530)

= 0.5608

= 0.561

Hence, the option c is correct.

Answer:

y-intercept=5

x-intercept=-2

Step-by-step explanation:

To find the y intercept, plug in 0 for x. So you get 10(0)-4y=-20. Simplify, and clear out the negatives on both sides because they cancel each other out. 4y=20 would be your final equation. y=5.

To find the x intercept, you plug in 0 for y this time. The equation is 10x-4(0)=-20. Simplify to get, 10x=-20. You cannot remove the negative because there isn't a negative sign on the 10x. -20/10 is -2.

Answer:

[tex]4.5[/tex]

Step-by-step explanation:

In order to find the answer to this question you will first need to convert Lincolns height into a improper fraction and then convert the improper fraction into a decimal number.

[tex]L =4\frac{5}{10}[/tex]

Convert into improper fraction

[tex]4\frac{5}{10} =10 \times4=40+5=45=\frac{45}{10}[/tex]

Convert into decimal by dividing the numerator by the denominator:

[tex]45\div10=4.5[/tex]

[tex]L=4.5[/tex]

Hope this helps.

Answer:

x ≥ 7

Step-by-step explanation:

First, put the same terms on the same side. So subtract 5 from both sides. You will get:

-3x ≤ -21

Divide both sides by -3 to get x alone. When dividing, the inequality sign will change to the opposite. So it will go from a (less than or equal to) sign to a (greater than or equal to) sign.

You will get:

x ≥ 7

Therefore, x will be a number that is greater than or equal to 7.

Answer:

[tex]n = \frac{1300}{5.50}[/tex]

[tex]n = 236[/tex]

Step-by-step explanation:

Given

The cost of printing one calendars [tex]= 5.5[/tex] dollars

The one time charge of taking photo [tex]= 200[/tex] dollars

The total sum of money with the club [tex]= 1500[/tex] dollars

The total sum of money going into printing of calendars [tex]= 1500 -200 = 1300[/tex] dollars

The total number of calendars that can be printed with remaining [tex]1300[/tex] dollars is equal to

[tex]n = \frac{1300}{5.50}[/tex]

[tex]n = 236[/tex]

The integer that represents the altitude change is -40

From the question, the positions of the eagle are

70 feet above him and 30 feet above him

Rewrite the positions of the eagle properly

This is done as follows

Position 1 =  70

Position 3 =  30

The expression of the altitude change in the position of the eagle is then calculated as

Change = Position 2 - Position 1

Substitute the known values in the above equation

So, we have the following equation

Change = 30 - 70

Evaluate

Change = -40

Hence, the altitude change is -40

Answer:

a) y = 4/3x + 26/3

b) 4x - 3y + 26 = 0

c) x-int: (-6 1/2, 0)

   y-int: (0, 8 2/3)

Step-by-step explanation:

a) to get points into the point-slope form you first find the slope by taking the difference of the y-values over the difference of the x-values;

slope (m) = (6 - 2) / (-2 - -5)  =  4/3

plug 4/3 into 'm' and select one of the two points to plug in their 'x' and 'y' values so you can find 'b' (the y-intercept)

y = mx + b

6 = 4/3(-2) + b

6 = -8/3 + b

b = 6 + 8/3 = 18/3 + 8/3 or 26/3 (or 8.67)

so, put it all together to get the p-s form of y = 4/3x + 26/3

b) general equation is Ax + By + C = 0

take y = 4/3x + 26/3 and multiply each side by 3 to remove denominators

you get: 3y = 4x + 26;  rearrange to get 4x - 3y + 26 = 0

c) y-intercept is (0, 8 2/3); derived during step (a)

to get x-intercept, plug zero in for 'y' and solve for 'x':

0 = 4/3x + 26/3

-4/3x = 26/3

cross-multiply and get 12x = -78

x = -78/12 or -39/6 or -6 1/2
