Answer:
92 meters
Step-by-step explanation:
Let x be the unknown, which is the height of the building.
3.3 m = x
1.78 m 49. 75 m
Solve for x.
(3.3 m) (49.75 m) = x
1.78 m
92.2331460674 = x
Rounded to the nearest meter, the building is 92 meters high.
Answer:
B.5
C.7
D.9
Step-by-step explanation:
a,b and c are the sides of a triangle if it satisfies:
a<b+c , b<a+c and c<b+a
Here, a=4 and b=7
We have to find c
i.e. all those c which satisfies:
4<7+c , 7<4+c and c<4+7=11
A.3 it is not true since it doesn't satisfies second inequality
B.5 it is true
C.7 it is true
D.9 it is true
E.11 This is clearly false, since it doesn't satisfies inequality third
F.17 This is clearly false, since it doesn't satisfies inequality third
Hence, correct options are:
B.5
C.7
D.9
The height must be 12.8.
We first find the volume of paint in the larger can. The formula for the volume of a cylinder is V=πr²h. Using the radius and height of the large can, we have
V=3.14(8²)(20) = 4019.2
Since he has 1/4 of the can left, he has 4019.2/4 = 1004.8 cm³ of paint.
Using this volume and the dimensions of the smaller can, we work backward to find the height of the paint in the can:
1004.8 = 3.14(5²)h
1004.8 = 78.5h
Divide both sides by 78.5:
1004.8/78.5 = 78.5h/78.5
12.8 = h
Answer:
100% - 2% = 98%
Or 100% x 0.98 = 98%
100% - 30% = 70%
Or
100% x 0.7 = 70%
Answer : 0.98 & 0.7
Thus, any number/price multiplied by these decimal multipilers - automatically, will give you the decreased values of the original values.)
For example, a £300 bag is on a sale for 2% off, how much does it cost?
£300 x 0.98 = £294 (final price of the bag)
Hope this helps!
