Plz help me .. I am really stumped!!!!!!! part of the set for a play is a big triangular piece of plywood. the area of the trian

saul85 [17]

The way to find the area of a triangle is A= $\frac{B*H}{2}$
if the base is 3 feet longer then the height we can write it like this B=H+3

now we can add it to our area equation
20= $\frac{H(H+3)}{2}$
20= $\frac{ h^{2} +3h}{2}$
40= $H^{2}$ +3H
10 $\frac{1}{3}$ = $H^{2}$
h=3.2ft

Solve. Write the solution in interval notation. -2x>-8 and -5x<20.

Novosadov [1.4K]

Answer:

The interval notation of the solution is (-4 , 4)

Step-by-step explanation:

* Let us explain a very important point in solving inequality

- When you multiply or divide an inequality by negative number we

must reverse the symbol of the inequality

- Ex:

∵ 2 < 3

- If we multiply the both sides of the inequality by -1, then the

inequality will be -2 < -3 and this is completely wrong, so we must

reverse the symbol of the inequality

∴ -2 > -3

* Now let us solve the problem

∵ -2x > -8

- Divide both sides by -2 and remember to reverse the symbol of the

inequality

∴ x < 4

∵ -5x < 20

- Divide both sides by -5 and remember to reverse the symbol of the

inequality

∴ x > -4

- From both solutions

∴ -4 < x < 4

∴ The solution is {x : -4 < x < 4}

- Interval notation is a way of writing the solutions of inequalities

( , ) if x does not equal the end numbers

[ , ] if x equals the end numbers

[ , ) , ( , ] if x equals one of the two end numbers

* The interval notation of the solution is (-4 , 4)

Danae is choosing between two jobs. One job pays an annual bonus of $1,500 plus $120 per day worked. The second job pays an annu

Zigmanuir [339]

Answer:

Step-by-step explanation:

Job A:

Bonus of $1500
$120 per day for $d$ days is 120 multiplied by $d$ . Which is $120d$
Total Payment = $1500+120d$

Job B:

Bonus of $2500
$110 per day for $d$ days is 110 multiplied by $d$ . Which is $110d$
Total Payment = $2500+110d$

Solving these 2 equations for $d$ would tell us after how many days both job would pay the same. Answer choice C is correct.
