It is 35% because you need to divide 21 out of 100 then multiply the answer you get by 7
Answer:
<em>Part A</em>: Explain why x = 5 makes 4x - 1 ≤ 19 true but not 4x - 1 < 19
<em>Part B: x=9</em>
Step-by-step explanation:
<u>Part A</u>: Because the first one is less than or equal to 19 and the other is just less than.
x = 5
TRUE: 4x - 1 ≤ 19 = 20-1 ≤ 19 = 19 ≤ 19
19 is less than or equal to 19 so its true
FALSE: 4x - 1 < 19 = 19 < 19
19 is not greater than 19
<u>Part B:</u>
5x + 2 = 47 subtract 2 from both sides
5x = 45 divide both sides by 5
x = 9
To check we can plug it back in
5x + 2 = 47
5(9) + 2 = 47
45 + 2 = 47
47 = 47
TRUE
Answer:
Volume=469cm³
Step-by-step explanation:
[tex]
Volume,V=Volume Cone + Volume\ of Hemisphere\\\\
Volume Cone,V1=\pi*r^2*\frac{h}{3}=\pi*4^2*\frac{12}{3}\\ \\
=201.06cm^3\\
Volume of Hemisphere,V2=2*\pi*\frac{r^3}{3}\\
=2*\pi*\frac{4^3}{3}=268.083cm^3\\
Volume=V1+V2=201.06+268.08\\
=469cm^3

Answer:
$122.375
Step-by-step explanation:
To find the total amount and tax, we need to multiply the original price by 1.375 in our case to get tax and the original price:
89×1.375=
$122.375
Answer:
the first set of values is correct
Step-by-step explanation:
when x =0,
y = 3(0) -1
y=-1
when x =1,
y=3(1)-1
y=2
when x=2,
y=3(2)-1
y=5
