Height of a triangle with base 5m and area 20m2

Answers

Since the "base of a triangular sail is 5m shorter than its height", we have the equality

Start with the formula for the area of a triangle

Plug in , , and

Multiply both sides by 2

Distribute

Subtract 36 from both sides

Factor the right side (note: if you need help with factoring, check out this solver)

Now set each factor equal to zero:
or

or  Now solve for x in each case

So our possible answers are

or

However, since a negative height doesn't make sense, our only solution is

So the height is 9 m

Now subtract 5 from the height to get the base

So the base is 4 m

Check:

Start with the formula for the area of a triangle

Plug in , , and

Multiply

Divide. Since the two sides of the equation are equal, this verifies our answer.

If you have a triangle with a base of 5m and an area of 20m2, to find the height begin with the formula of the area of a triangle.

A=1/2bh

Then, plug in your known numbers

20m2=1/2h(5m)

What I do next, is I work backwards by dividing the are by 1/2, which equals 40. All that is left to do, is divide this number, 40, by 5 to find the height.

40/5=8

Therefore, the height of the triangle is 8m

−8x+3≥27 AND−13x+5≥57

Answers

Answer:

$x \leq -4$

Step-by-step explanation:

$-8x+3\geq 27 and -13x+5\geq 57$

LEts solve each inequality separately. then we find the intersection of both solutions.

$-8x+3\geq 27$

Subtract 3 on both sides

$-8x\geq 24$

Divide both sides by $-8$ , change the inequality symbol when we divide by negative number

$x \leq -3$

Now solve the other inequality

$-13x+5\geq 57$

Subtract 5 on both sides

$-13x\geq 52$

Now divide both sides by $-13$

$x \leq -4$

Now we take the intersection of $x \leq -3$ and $x \leq -4$

for $x \leq -3$ , we shade the number line to the left

$x \leq -4$ , shade the number line to the left

Intersection of both graph is $x \leq -4$

the circumference of the cookie jar, and the diameter of the cookie jar?

Answers

Answer:

D - 75.40 inches

Step-by-step explanation:

If it is its diameter, then we must do a little calculation, multiplying the diameter by Pi to reach 75.40 inches.

-73 greater than or equal to 15 + 11x

Answers

-73 ≥ 15 + 11x
so the first thing you should do is to add -15 on both sides of the equation so you will have:
-73 -15 ≥ 11x
- 88 ≥ 11x
so the answer is:
-88/11 ≥ x or -8 ≥ x :)))
i hope this is helpful
have a nice day

-73 ≥ 15 + 11x

Simplify both sides of the inequality

-73 ≥ 11x+15

Flip the equation

11x+15 ≤ -73

Subtract 15 from both sides

11x+15-15 ≤ -73 -15

11x ≤ -88

Divide both sides by 11

11x/11 ≤ -88/11

x ≤ -8

I hope that's help !

There were 12 3/4 cups of orange juice in a car in each day Alberto drink one one fourth of orange juice today there is 1/4 cup of orange juice left for how many days has Alberto drink orange juice

Answers

You start out with 12 3/4 cups of orange juice. Alberto drinks 1/4 cup of orange juice per day. So you need to divide 12 3/4 by 1/4. Then you subract 1/4 from it to get 50 days. Alberto drank 1/4 cup of orange juice for 50 days.
