number of hours she can rent is a maximum of 3

Step-by-step explanation:

h = hours bike is rented

1.75h + 5 ≤ 10.25

subtract 5 from each side:

1.75h ≤ 5.25

divide each side by 1.75:

h ≤ 3

[RevyBreeze]

Answer:

7.463%

Step-by-step explanation:

$720 - $670 = $50

the sales tax price = $50

sale tax in percentage =

[tex] \frac{tax}{computer \: price} \times 100 =[/tex]

[tex] \frac{50}{670} \times 100 = 7.462[/tex]

Step-by-step explanation:

so, we first put 10 in for x :

y = 6.50×10 + 50 = 65 + 50 = $115

and then we put 20 in for x :

y = 6.50×20 + 50 = 130 + 50 = $180

so, the ordered pairs are

(10, 115) and (20, 180)

Answer:

x = 5

Step-by-step explanation:

-10x - 1 = -51

add 1 to each side

-10x = -50

divide each side by -10

x = 5

Answer:

3 moths and 10 days

Step-by-step explanation:

on each day she gets 1$ that means

1 month = 30 days

e.g. 3 6 9   30 60 90

means 90 days if we add also 1 month it will be 120 days

so 90 +  10 = 100

thats why 3 months and 10 day :)

Answer:

y-intercept = (0, 8)

x-intercepts = (4, 0) and (-2, 0)

vertex = (1, 9)

5th point = (2, 8)

Step-by-step explanation:

As the coefficient of x² is negative, the curve will be "n" shaped.

y-intercept

crosses the y-axis when x = 0

substitute x = 0 into the function and solve for y:

[tex]\implies y=-(0)^2+(2 \times 0)+8=8[/tex]

Therefore, y-intercept = (0, 8)

x-intercept

crosses the x-axis when y = 0

set the function to zero and solve for x:

[tex]\implies -x^2+2x+8=0[/tex]

[tex]\implies x^2-2x-8=0[/tex]

[tex]\implies (x-4)(x+2)=0[/tex]

[tex]\implies x=4, x=-2[/tex]

Therefore, x-intercepts = (4, 0) and (-2, 0)

vertex

vertex form:  [tex]y=a(x-h)^2 +k[/tex],  where (h, k) is the vertex

expand vertex equation:  [tex]y=ax^2 -2ahx+ah^2 +k[/tex]

compare coefficients with original function: [tex]y=-x^2+2x+8[/tex]

[tex]\implies a=-1, h=1, k=9[/tex]

So vertex = (1, 9)

5th plot point

You can choose any value of x and input it into the equation for y, but for symmetry, I have chosen to find the other value of x (aside x = 0) when y = 8

[tex]\implies -x^2+2x+8=8[/tex]

[tex]\implies -x^2+2x=0[/tex]

[tex]\implies x^2-2x=0[/tex]

[tex]\implies x(x-2)=0[/tex]

[tex]\implies x=0, x=2[/tex]

5th point = (2, 8)

Answer:

942m^2

Step-by-step explanation:

to find the answer you do pi * r^2 *h

pi is 3.14 r is 5 and h is 12= 3.14* 5^2 * 12

now you have 78.5*12

now you're left with your answer 942m^2

Answer:

5

Step-by-step explanation:

0(0×2 + 0 + 1) + 5

0(0+0+1)+5

0 + 0 + 0 +5

= 5

Step-by-step explanation:

• the original price= 275,

275 → 100 %

i) find the price with the 15 % discount

100% - 15% = 85 %

if, 275 → 100 %

100 % → 275

1% → 275 / 100

85 % → (275/100) * 85

= 233. 75

ii) find the add. 5% of the :

sale price = 233. 75

add. discount = 5%

= 5/ 100 * 233.75

= 11.6875

iii) subract the 5% discount from the sale price.

final price = 233. 75 - 11.6875

= 222. 0625

The total cost of the two shirt Maggie will pay after including the sales tax is $18.105.

The cost price per unit is the amount of money required to buy one unit of a brand or goods.

To find the cost price per unit, divide the total amount of cost of the goods to the total number of goods.

The cost of one shirt bought by the Maggie is $8. 50 each. Thus, the cost of the 2 shirts is,

[tex]C=2\times8.50\\C=17[/tex]

Thus, the total cost of the two shirts is $17.

Now, there is a 6. 5% sales tax on the selling price. Thus, the cost of the 2 shirts after the sales tax is,

[tex]C=17+17\dfrac{6.5}{100}\\C=17+1.105\\C=18.105[/tex]

Hence, the total cost of the two shirt Maggie will pay after including the sales tax is $18.105.

Answer:

x = 130°

y = 50°

Step-by-step explanation:

x = 130° (Exterior alternate angles)

x + y = 180° (Angles in linear pair)

y = 180° - x

y = 180°- 130°

y = 50°

The solution to the problem in the figure attached in the question is: x = 130°, y = 50°

Alternate angles are angles that are formed in a situation whereby a line intersects two other lines, which lie on opposite sides of a transverse line and on contrasting proximate sides of the other lines.

From the given figure:

Angle x is an alternate angle to angle 130°.

Thus, x = 130°

Using the sum of angles on a straight line:

x + y = 180°

130° + y = 180°

y = 180° - 130°

y = 50°

Answer:

70

Step-by-step explanation:

First, set up the ratio of c:t, which is 12:8. Then set up your new ratio of c:t, which is 105:?. The way I find the easiest is to divide 105 by 12, which is 8.75, then multiply that by 8, which is 70. To check if it's right, just divide 12 by 8, and 105 by 70, and if they're the same number, you've got it right.
