Answer:
46.08
Step-by-step explanation:
you have to make your percentage a decimal, which 60% will be .60 and 20% will be .20. you then multiply your initial number which is 36 by .60 and add that on because youre adding 60%. After that you will multiply that given number by .20 and you subtract what that product is from your last product you received (36x.60) which if im not mistaken will give you $46.08.
Answer:
Both
1 ≥ 2x
and
6x ≥ 3 + 8x – 4
Step-by-step explanation:
Correct representations are representations which are equivalent and represent the exact same relationship. To find these, you can simplify the inequality.
6x ≥ 3 + 4(2x – 1)
6x ≥ 3 + 8x - 4
6x ≥ 8x - 1
-2x ≥ -1
2x ≤ 1
x ≤ 1/2
Answer:
1.25cm
Step-by-step explanation:
<em>Complete question:</em>
The prism has a volume of 35 cm cubed workout h, the height of the triangular cross section
<em>length=7cm</em>
<em>width = 4cm</em>
<em></em>
The volume of the prism is expressed as;
Volume = Base Area * Height
Given
Volume of the prism = 35cm^3
Base Area = length * width
Base Area = 7cm * 4cm
Base Area = 28cm^2
Substitute the given values into the formula
35 = 28* Height
Cross multiply
35 = 28 * Height
35 = 28 Height
Height = 35/28
Height = 1.25cm
Hence the height of the triangular cross section is 1.25cm
Answer:
x ≤ - 5
Step-by-step explanation:
Given
- 2x - 1 ≥ 9 ( add 1 to both sides )
- 2x ≥ 10
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
x ≤ - 5
Answer:
<u>Width = 7 inches</u>
<u>Length = 23 inches</u>
Step-by-step explanation:
Let :
Equating to area :
- (2x + 9)(x) = 161
- 2x² + 9x = 161
- 2x² + 9x - 161 = 0
- 2x² - 14x + 23x - 161 = 0
- 2x(x - 7) + 23(x - 7) = 0
- x - 7 = 0
- x = 7
Dimensions are :
- <u>Width = 7 inches</u>
- Length = 2(7) + 9
- <u>Length = 23 inches</u>
