Answer:
$77
Step-by-step explanation:
The answer is $77 because first you need to find how much money was discounted by doing 70-49 to get 21. Then you need to find how much percent 21 is of 70 by doing 21/70, then you would get 0.3 which is 30% since you have to multiply it by 100. This means that there is a 30% discount. Then you would do 0.3*110=33. This means that the 30% discount takes away $33. So 110-33=77. The answer is $77.
It rained 1 and 4/10 centimeters. You have to first figure out what adds up to 14, which is 1/10. Then you add 1 to get 15 and 3/10 to get 15 3/10.
Answer:
B
Step-by-step explanation:
The equations are:
2x + y - 7 = 0
and
1/3x + y -4 = 0
Let's rearrange the first to get:
y = -2x + 7
Putting this into the 2nd equation we get:

Now, y would be:

Solving the equation we see that there is 1 unique solution with 1 x value and another y values. That means, when graphing, the lines would intersect.
Answer choice B is right.
<u>Note:</u> Coincident means the same line and parallel means there would be no solution when solving
The answer to this questions is 70kg.
Answer:
Area of Tamara room
=9556 square feet
Width
=813 feet
Length= 11.75 feet
Total area= 19794 square feet
480 square feet will not be enough
Step-by-step explanation:
Dimensions of Tamara's room to the nearest whole numbers
Area of Tamara room
=9556 square feet
Width
=813 feet
For the length
Length*width= area
Length= area/width
Length= 9556/813
Length= 11.75
To the nearest whole number = 12 feet
The ceiling is 12 feet high
Let's calculate for the area of the combination
1)Height and width two times
2)Height and length two times
1).area = 12*813
= 9756
Then 9756*2= 19512
2). area= 12*11.75
= 141
Then 141*2= 282
Total area = 282+19512
Total area= 19794
