A sheet of paper is 8.5 in X 11 inches if you cut 2 in squared from each corner what is the area if the paper

1 answer:

3 0

A=length x height. First we want to know the area of the original sheet of paper. 8.5 x 11= 93.5 inches squared. Then we take two squares with side length 2 inches. The area of each of these squares is 2 x 2, or 4 inches. Since there are two, the total area we take away is 8 inches. We subtract 8 inches from 93.5 since we took it away, and the final area of the paper is 85.5 inches^{2}

Hope this helped!

Pinto is planning to paint the walls of a bedroom that is 20 feet long, 15 feet wide, and 8 feet high. Is he too has 1 gallon of

eimsori [14]

Answer:

0.4 gallons

Step-by-step explanation:

Length of a bedroom= 20 feet

Breadth of a bedroom= 15 feet

Height of a bedroom= 8 feet

Area of walls of a bedroom= 2(l+b)×h

Area of walls of a bedroom=2(20+15)×8 $ft^{2}$

Area of walls of a bedroom= 2× 35×8 $ft^{2}$

Area of walls of a bedroom=560 $ft^{2}$

Amount of paint in 1 gallon = 400 $ft^{2}$

Number of gallons required= $\frac{560}{400}$

Number of gallons required= 1.4 gallons

Hence, 0.4 extra gallons required

Make b the subject.

sp2606 [1]

First, square both sides. This will cancel out the radical.
$a^2 = b \add 6$
(a^2 = b + 6)
Then subtract 6 from both sides
b = a^2 - 6

Please help me with question 2

WARRIOR [948]

Answer:

sin(-a)= -15 /17

Step-by-step explanation:

Alright, lets remember that sin(x) is odd function, which means that

wherever you watch an expression like this: sin(-a), you can use the odd functions property, and turn it like the following

sin(-a)= - sin(a)

Now, other thing to remember: $(sin(x))^{2}+(cos(x))^{2}=1$

So, we can obtain any value for sin(x) function starting from the opposite function, cos(x), using the following:

$sin(x)=\sqrt{1-(cos(x))^{2} }$

So, if cos(a)= - 8 / 17, using the above equation we obtain the value for sin(a)

$sin(a)=\sqrt{1 - (cos(a))^{2} } = \sqrt{1 - ( \frac{8}{17} )^{2} }= \sqrt{\frac{225}{289} } =15/17$

Using the odd function property, we get the following result

sin(-a)= - sin(a) = -15/17
