The line DB is 8cm which is made up of DE and EB which are equal to each other, thus DE and DB are both 4 cm.
Secondly, since AC and DB are perpendicular, that means angle DEC and angle DEA are ninety degrees.
Thus using the Pythagorean theorem, we can find the length of AE and EC which we can add up to find the length of AC.
[tex]AE = \sqrt{AD^2-DE^2} =\sqrt{5^2-4^2} =\sqrt{25-16} =\sqrt{9}=3\\ \\EC=\sqrt{DC^2-DE^2}=\sqrt{6^2-4^2}=\sqrt{36-16} =\sqrt{20} =2\sqrt{5} =4.47[/tex]
By adding AE and EC, we get that the length of AE and EC is 7.47 or as approximated to the nearest tenth 7.5.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Here, 8% of x is 12.5
8% of x= 12.5
8/100 ×x= 12.5
0.08x=12.5
x=12.5/0.08
x= 156.25
Therefore, 8 percent of the number 156.25 is 12.5.

Answers
Based on Lauren's income and the various deductions, the net pay for April is $1,151.44.
What is the taxable income?Taxable income:
= Semimonthly income - 401k - Section 125 plan
= (51,680 / 24 pay periods) - (0.03 x 51,680/24 periods) - 139
= 2,153.33 - 64.6 - 139
= $1,949.73
What is Lauren's April net pay?= Taxable income - federal income tax - state income tax - social security - Medicare - advance repayment

Store X, because the sale price would be $68
Step-by-step explanation:
vStore X, because the sale price would be $68
Assuming at Store Y all cameras are on sale for off the original price. The store with the better sale price is: Store y, because the sales price is $64.
Store x and yStore x
x=80×(1-0.15)
x=80×0.85
x=68
Store y
y=80×(-1/5+1)
y=80×4/5
y=64
y=64≤68
Based on the above calculation store y is the best.
Inconclusion the store that would have the better sale price is: Store y, because the sales price is $64.

subtracting equation 3
0.21y+0.21y =12.6

Answers
Answer:
L=54+2d
L=54+2*39
L=54+78
L=132
Answer:
L = 2D + 54
132 miles
Step-by-step explanation:
Starting length: 54
Additional length each day: 2
On day 0, the additional length is 0.
On day 1, the additional length is 2 × 1
On day 2, the additional length is 2 × 2
On day 3, the additional length is 2 × 3
...
On day D, the additional length is 2 × D or simply 2D.
The total length after D days is the original length plus the total amount of the daily additions.
The equation is:
L = 2D + 54
On day 39, D = 39
L = 2D + 54
L = 2 × 39 + 54
L = 78 + 54
L = 132
Answer:
L = 2D + 54
