I believe there is an error because none of them are the answers
Step-by-step explanation:
4y=6
y=6/4
y-1=-14
y=-13
214+y=4
y=-210

x = -5
the second case;
+ 3 = 
= 
x = -7
please give me a brainliest answer
We have that
1)
cot 70=x/12
Cot
70=[opposite side]/[adyacent side]=x/12
The
option 1 is correct
2)
cot 70=12/x
Cot
70=[opposite side]/[adyacent side]=x/12
The
option 2 is not correct
3)sec 20=x/12
Sec 20
=1/cos20
Cos
20==[opposite side]/[hypotenuse]=12/z
1/(1/cos20)------->
1/(12/z)------> z/12
The
option 3 is not correct
<span>
4) sec 20=12/x</span>
Sec
20 =1/cos20
Cos
20==[opposite side]/[hypotenuse]=12/z
1/(1/cos20)------->
1/(12/z)------> z/12
<span>The
option 4 is not correct</span>
the correct value is
1) cot 70=x/12
Answer:
- 1.5 times
- bottle Y
- third bottle
Step-by-step explanation:
Insufficient dimensions are given to compute an exact volume of each geometry, so we have to assume that the volume is proportional to the product of base area and height. Then the relative volumes will be ...
bottle X: (6 in)(2 in)(1 in) = 12 in^3
bottle Y: (4 in)(3 in)(1.5 in) = 18 in^3
3rd bottle: (3 in)(6 in^2) = 18 in^3
That is, the relative volumes are ...
X : Y : 3rd = 12 : 18 : 18 = 1 : 1.5 : 1.5
The corresponding relative prices are ...
X : Y : 3rd = 9.96 : 14.40 : 13:20 = 1 : 1.446 : 1.325
__
A. Bottle Y has 1.5 times as much lotion as Bottle X.
__
B. Bottle Y is a better buy than Bottle X. (The price relative to X is less than the volume relative to X.)
__
C. The 3rd bottle is the best buy. For the same volume, the price of the 3rd bottle is less than that of Bottle Y.
_____
Note that the relative volume and price ratios are found by dividing all the numbers in the ratio sequence by the first number:
12 : 18 : 18 = (12/12) : (18/12) : (18/12)
9.96 : 14.40 : 13.20 = (9.96/9.96) : (14.40/9.96) : (13.20/9.96)
