An equilateral triangle has sides of length 10 cm.
**DIAGRAM IN PICTURE**

a. Calculate the perpendicular height, h, of the triangle.

b. Calculate the area of the triangle.

Give your answers correct to one decimal place. 10 cm 10 cm 10 cm

Answers

Answer:

a. 8.7cm

b. 43.5cm squared

Step-by-step explanation:

a. draw the triangle with a side length of 10cm, and measure the height which is 8.7cm.

b. formula to find the area  of a triangle: (base into height) divided by 2 ((b x h) / 2)

the base is 10

the height is 8.7

(10 x 8.7)/2 = 87/2 = 43.5 cm squared

A is 8.7cm

Step-by-step explanation:

P(red or purple) = number of red or purple / total

There are 7 red rings and 10 purple rings

                          = 17/50

17/50
There are 7 red rings, and there are 10 purple rings, If you add all the rings together, it is out of 50, therefore it is 17/50

The goalie on the Iceblades hockey team saves (blocks) 73% of the opponent's shots. With 10 minutes to go, the Iceblades are ahead by one goal, and they will win if the other team does not score.
The other team takes 5 shots in the final 10 minutes. The Iceblades do not score any more goals.
The table shows pairs of random digits. The pairs in each group simulate the 5 shots taken by the opponent.
Answer the questions to estimate the probability that the Iceblades will win the game.


1. The paired digits 00 to 99 represent 100 shots.
Let 00 to 72 = a shot that is saved. Which digits represent a goal scored? Explain.


2. Each group represents the 5 shots taken by the other team. To win the game, the Iceblades cannot let the other team score any goals.
For a group to be a success, how many of the 5 shots does the goalie need to save?


3. Group 1 is a success. Explain why.


4. In this simulation, which groups are successes? How many successes are there in the 10 groups?

ok yeah I can find what the name is but how in the heck do I find the value of x?!!! directions in photo no links or your getting reported!!!!!

Answers

This is an isosceles triangle, as indicated by the two lines on two sides (they are equal). One angle is 45 degrees, as indicated. We know that the angles of the two equal sides are equal as well. Knowing that all triangles sum up to 180 degrees, we can subtract 45 from 180 and divide by two to get each equal angle.

Here it is:

180-45=135

135 divided by 2 is 67.5.

This means that the value of x is 67.5 degrees.

To check, we can add all of the sums and it should be 180 degrees.

45+67.5+67.5=180

∴ x= 67.5 degrees

Take what a triangle equal up to them subtract 45

Solve the system of equations by substitution.

-8x+2y=4
y=4x+2

Answers

Answer:

the answer by substitution would be y = 4x+2

Correct answer: Infinite solution because 2 = 2.

Set the first equation equal to y.

-8x + 2y = 4

+8x          +8x

___________

2y = 8x + 4

__   ___  __

2      2     2

y = 4x + 2

At this step, you can choose any equation to substitute into the other equation. However, I'm going to substitute the new first equation with the second equation where y is. Solve for x.

y = 4x + 2

4x + 2 = 4x + 2

-4x        -4x

____________

2 = 2

So, at this point, we know the system of equation does not have one solution. Thus, when the same number equals the same number, it is an infinite solution.

We can prove this by an online graphing tool. Insert the two equations onto the online graphing tool. If the lines appear to be on the same line, they have infinite solutions. Hope this helps :) Let me know if you have any questions related to this problem!

In the diagram below, DF = JL = a, FE = LK = b, and triangle DEF is a right triangle.
Use the drop-down menus to complete the proof that if the equation a² + b2 = c2 is true of
the side lengths in triangle JKL, then triangle JKL must be a right triangle.

Answers

ΔDEF and ΔJKL are congruent to each other.

.

What is Congruency?

Congruent triangles are triangles that have the same size and shape

This means that the corresponding sides are equal and the corresponding angles are equal.

Given

DF = JL = a, FE = LK = b, ΔDEF is a right triangle.

As Pythagoras theorem can be used in ΔDEF.

Also  ΔJKL Hence angle K is the right-angle.

As, ∠F = ∠L = 90°,

         DF = JL = a,

       FE = LK = b

Hence, ΔDEF and ΔJKL are congruent to each other.

In the course of a short race, a car does 50,000 J of work in 7 s. What is the power of the car during the race? (round to the nearest whole number)

Answers

Answer:

Work done is the product of distance and force, it is measured in joules.

Power is the rate of work done given by dividing the work done by time

Power (watts)= workdone (J)/ time (s)

                     = 50,000J/7 sec

                     = 7142.857 watts

Therefore, the power of the car during the race was 7142.857 watts
