Answer:

611 square miles

Step-by-step explanation:

Area of triangle = (1/2)*a*b*sinC (formula when u are not given the height of the triangle, but u are given with the angle.)

= (1/2)*30*47*sin(60°)

= 610.54 square miles (2 d.p)

≈611 square miles (rounded to nearest mile)

(x+y,y+3)=(6,2y) find the value of x and y

trasher [3.6K]

Step-by-step explanation:

Solution:

Given:-

(X+y,y+3)=(6,2y)

Equating corresponding elements,we get,

X+y=6------(1)

y+3=2y-----(2)

solving equation (2),

y-2y=-3

-y=-3

y=3.

Now, substituting y=3 in equation (1)

X+3=6

X=6-3

X=3

Therefore,. (X,Y) = (3,3)

A = a+b+c/3 Solve for b this is a literal equation problem please show steps

Elan Coil [88]

Answer:

$b=3A-a-c$

Step-by-step explanation:

$A=\frac{a+b+c}{3}$

Multiply both sides by 3

$3A=a+b+c$

Add $-b-c$ both sides

$3A-a-c=b$

$b=3A-a-c$

the owner od the theater in item 18 wants to make at least $400 at each performance. let x be the number of adult tickets and y

GenaCL600 [577]

Answer:

The inequality representation is : x + y ≥ $400

Step-by-step explanation:

Inequality is the comparison and boundary for two non equal values. So inequality compares the non equal values.

As the owner wants to make $400 and sets boundary that;

Least amount to make = $400

Highest amount to make= infinite

This introduces relation in inequality as $400 or greater than $400.
The money made is counted combine from child tickets and adult tickets. If x is the made made through child tickets and y is from the adult then,

x + y ≥ $400

PLZ HELP ME WILL GIVE BRAINLIEST

nadezda [96]

Answer:

1. $2 \times 10^{- 4} = 2 \div 10^{4}$

2. $(- 10)^{2} = 100$ and $- 10^{2} = - 100$

3. $(a.b.c. ........)^{n} = a^{n}.b^{n}.c^{n}. ..........$

Example: $(30)^{4} = (2 \times 3 \times 5)^{4} = 2^{4} \times 3^{4} \times 5^{4}$

Step-by-step explanation:

1. We have $2 \times 10^{- 4}$ , and we have to prove that this term is equivalent to $2 \div 10^{4}$ .

Now, $2 \times 10^{- 4}$

= $2 \times \frac{1}{10^{4} }$

{Since we know the property of exponent as $a^{- b} = \frac{1}{a^{b} }$ }

= $\frac{2}{10^{4} }$

= $2 \div 10^{4}$

2. $(- 10)^{2} = (- 10) \times (- 10) = 100$ and

$- 10^{2} = - [(10) \times (10)] = - 100$

3. The power of products property gives

$(a.b.c. ........)^{n} = a^{n}.b^{n}.c^{n}. ..........$ ........ (1)

For example, we can write, $(30)^{4} = (2 \times 3 \times 5)^{4} = 2^{4} \times 3^{4} \times 5^{4} = 810000$
