First you need to know the definition of a complementary angle. That means that two angles add up to 90 degrees, or a right angle.
To find an angle complementary to a 78 degree angle, you need to subtract 78 from 90.
90 - 78 = 12
Living Room Area = 17.5 x 20 = 350 sq ft
Hall Area = 4 x 12 = 48 sq. ft.
Total area of carpeting: 340 + 48 = 398 sq. ft.
We need to convert total area in sq ft to sq yd. The conversion ratio is
1 sq ft = 0.11 sq yd
So, 398 sq ft would be:
398 * 0.11 = 44.22 sq yd.
Carpet removing rate is 5.99 per sq yd.
Removing rate would be:
44.22 * 5.99 = $264.88
Assuming you gotta install both carpet and pad,
Carpet + pad = 16.99 + 3 = 19.99 per sq yd.
You gotta buy for 44.22 sq yd.
So, it will cost (carpet):
44.22 * 19.99 = $883.96
Installing rate 4.50 per sq yrd, so to carpet 44.22 sq yd, would need:
4.50*44.22 = $198.99
Assuming carpet is provided by installation guys, total charge:
<h2>264.88 + 883.96 + 198.99 =
$1,347.83</h2>
There are 156 rows of trees altogether.
<u>Step-by-step explanation:</u>
Given that for every 11 rows of Red delicious , they plant 3 rows of Royal Gala.
Thus for 1 row of Royal Gala there would be 11/3 rows of Red delicious.
Number of rows of Royal Gala=18
For 11 rows of red delicious,they plant 7 rows of yellow delicious.
Thus for 1 row of Red delicious,there would be 7/11 rows of yellow delicious.
For 66 rows of red delicious there would be
For 11 rows of red delicious,they plant 5 rows of Braeburn
for 1 row of red delicious,they would plant 5/11 rows of Braeburn.
For 11 rows of red delicious,they would plant
Total rows of trees=66+42+30+18=156
Answer:
I'm pretty sure it's D, sorry if I'm wrong
Step-by-step explanation:
Answer:
The number of the television sets that is model p is 12
Step-by-step explanation:
Here we have total number of television sold = 40
The model p televisions sold for $30 less than the model q televisions
That is $P = $q - $30
Therefore
Let the quantity of the model p sold be X
Let the quantity of the model q sold be X
Therefore
x + y = 40
Total cost of the television = 40 * 141 = $5640
Therefore, 120*x + 90*y = 5640
Plugging in x = 40 - y in the above equation we get
4800 - 30y = 5640 or
y = -28 and
x = 68
If we put y = 40 - x we get
30x + 3600 = 5640
If we put
120*x + 150*y = 5640.........(3)
we get
x = 12 and y = 28
Therefore, since the model p sold for $30 less than the model q, from the solution of equation (3) the number of the television sets that is model p = 12
