Answer:

Plug in and determine solution

Step-by-step explanation:#9-11 plug in the degrees C on the left side of the table into the equation and that should give you the degrees F, something like with #9; F = 9/5 (0) + 32.

#12-13, they have a relationship because Celsius can be converted to Farenheit and vise versa

One side of a triangular lot is 150 ft and the angel oppiste this side is 55 degrees. Another angel is 63 degrees. Determine how

Olenka [21]

Answer:

474.84 ft of fencing is needed

Step-by-step explanation:

We know that the angles of a triangle sum up 180º. We already know 2 of the triangle's angles (55º and 63º). Therefore the third angle measures:

180 - 55 - 63 = 62.

To know how much fencing is needed, we need the perimeter of the triangle, so we need to find out how much the other sides of the lot measure.

We will use law of sins to solve this problem.

First we solve for y:

$\frac{150}{sin55}= \frac{y}{sin63} \\y=150 (sin63)/(sin55)\\y=133.65/.8191\\y=163.16$

Now we solve for the other side of the lot, x:

$\frac{150}{sin55}=\frac{x}{sin62}\\ x=150(sin62)/(sin55)\\x=150(.8829)/.8191\\x=132.435/.8191\\x=161.68$

Now that we have the measures of all the sides we sum them up

total fencing needed= 150 + 163.16 + 161.68 = 474.84

A shopkeeper marks the price of an calculator at 25% above cost price. He then allows a discount of 15% of the marked price and

Amanda [17]

Answer:

Rs. 18000

Step-by-step explanation:

$x(1 + 25\%) \: (1 - 15\%) - x = 900$

$1.0625x - x = 900$

$0.0625x = 900$

$x = 14400$

•••••

$14400 \times (1 + 25\%)$

$\: \: \: \: \: \: \: \: = 14400 \times 1.25$

$\: \: \: \: \: \: \: \: =Rs. 18000$

The marked price of a calculator is $\boxed{\green{Rs. 18000}}$

Katie wants to buy a scooter that usually sells for $95.99. The store is having a sale and all merchandise is discounted by 20%

s2008m [1.1K]

Answer:

$82.55

Step-by-step explanation:

95.99/100=0.9599

0.9599x80=76.792

76.792/100=0.76792

0.76792x7.5=5.7594

76.792+5.7594=82.55
