Mathematics
1 answer:
Vaselesa [24]3 years ago
3 0

Answer:

y = 10

Step-by-step explanation:

Since FI and HI are equal to each other, we can set the equations equal to each other.

13y - 85 = y + 35

Add 85 to both sides, then subtract 1y from both sides.

12y = 120

Now divide by 12 on both sides.

y = 10 is the answer.

The length of one side of a square field is represented by the expression 3-7x.
Juliette [100K]

They give us the length of side of the square which is 3-7x.

To get an expression for the perimeter that is expressed as a product we have to multiply the expression 3-7x by four since every square has four sides. This will give us an expression of 4(3-7x). We than can use the distributive property to multiply everything inside the parenthesis by 4. This will give us an expression of 12-28x.

Plsssssss help<br>got 20 mins​<br>the question is: The sin of angle DCB is
Elena L [17]

Answer:

i. <DCB = 53.13^{o}

ii. Sin of <DCB = 0.8

Step-by-step explanation:

Let <DCB be represented by θ, so that;

Sin θ = \frac{opposite}{hypotenuse}

Thus from the given diagram, we have;

Sin θ = \frac{4}{5}

        = 0.8

This implies that,

θ = Sin^{-1} 0.8

   = 53.1301

θ = 53.13^{o}

Therefore, <DCB = 53.13^{o}.

So that,

Sin of <DCB = Sin 53.13^{o}

                    = 0.8

Sin of <DCB = 0.8

Cameron sponsor a fun raiser that 582 people attended he raise $6480 he charged $15 for balcony seats and $10 for crown seats ho
bagirrra123 [75]

Answer:

132 people bought balcony tickets and 450 bout ground tickets

Step-by-step explanation:

let x be balcony and y for ground

x+y=582

15x+10y=6480  solve by adding(subtracting)/eliminating process

multiply first equation by 15 to eliminate x:

15x+15y=8730

15x+10y=6480      subtract

15x+15y-15x-10y=8730-6480

5y=2250

y=2250/5=450

x+y=582

x=582-450=132
