Answer:
c
Step-by-step explanation:
you would put -142 in the x place
-0.2(-142+223)
-0.2(81)=-16.2
Answer:
Answer is D
Step-by-step explanation:
First use sine to figure out x
so "sin(31) = 12 ÷ x"
mulitply both sides by x and you get "x * sin(31) = 12"
divide both side by sin(31) so you get "x = 12 ÷ sin(31)"
after plugging it in a calculator, you get 23.2992 and just rounf to the nearest tenth and you get 23.3
X < 43, implies that the height of Aisha is less than 43 and can't be equal to 43 ( as there is no equal operator)
A is wrong as the inequality does not imply that Aisha is 0 tall , but any height height from 0 to 42.99999...
B) Correct , Aisha is not 43 and less she is less than that.
C) no, she may just need to grow 1 or 2 inches who knows.
D) nope, Aisha is at most 43 ( at least = 43 or taller)
at most 43 or less
Given:
Perimeter = 18 m
The formula for the perimeter of a rectangle is:
Where:
l = lenght
w = width
In this case, we have that:
l = 2w
Therefore, we substitute the values in the formula:
And solve for w:
For the length:
Answer:
The width is 3 m
The length is 6 m
Answer:
Invested at 11% : 3100
Invested at 6% : 3200
Step-by-step explanation:
let x= amount invested at 11%
let y= amount invested at 6%
we can write
Equation 1: x+y=6300
Equation2: .11x+.06y=533
Divide equation 2 by .06 to get
1.8333333x+y=8883.33333333
Subtract equation 2 from equation 1
.8333333x= 2583.33333333
x= 3100
Plug in x= 3100 into equation 1
3100+y= 6300
y= 3200
