DiKsa [7]

Answer:

2109 meter squared

Step-by-step explanation:

Area  \: of \:  path  \\ = (400+3)(300+3)-400 \times 300 \\  = 403 \times 303 - 120000 \\  = 122,109 - 120000 \\  = 2109 \:  {m}^{2}

The cost of 3 markers and 2 pencils is $1.80. The cost of 4 markers and 6 pencils is $2.90. What is the cost of each item? Inclu
RideAnS [48]
Let M = marker cost
Let P = pencil cost

3 markers and 2 pencils cost 1.80 ==> 3M + 2P = 1.80

4 markers and 6 pencils cost 2.90 ==> 4M + 6P = 2.90

Multiply the first equation by (-3) and add it to the second equation

-9M - 6P = -5.40
4M + 6P = 2.90

-5M = -2.50
M = 0.50

Plug this value for M into the 1st equation and solve for P

3*(0.50) + 2P = 1.80
1.50 + 2P = 1.80
2P = 0.30
P = 0.15

So a marker costs 50 cents and a pencil costs 15 cents

If <br>a+e = 11<br>a²-f=15<br>f+c=6<br>c×a-e=13<br>what is the value of the variables​
CaHeK987 [17]

Answer:

a=4

c=5

e=7

f=1

Step-by-step explanation:

the simplest method would be to start with a(2)"squared" (being '4' as this will get you closest to 15. So 16 -1 (being 'c') = 15. now plug those into the other equations and work the other numbers out.

In ΔOPQ, the measure of ∠Q=90°, OQ = 24, QP = 7, and PO = 25. What is the value of the tangent of ∠O to the nearest hundredth?
Debora [2.8K]

Answer: 0.29

Step-by-step explanation:

OQ is the side opposite angle P, QP is the side opposite angle O, and PO is the side opposite angle Q.

This means that tangent = opposite/adjacent, the tangent of angle O is the opposite side, QP, over the length of the adjacent side, OQ. (It cannot be PO since that's the hypotenuse)

This means that the tangent of O is 7/24, which is about 0.29
