The length of the base of an isosceles triangle is x. The length of a leg is 3x - 4. The perimeter of the triangle is 76. Find x.
X=

Answers

Answer 1

Answer:

12

Step-by-step explanation:

Hi!

We're given that the perimeter is 76. A triangle's perimeter is given by the sum of all of the sides. So, we'll find the lengths of the sides of the triangle and add them.

This is an isosceles triangle. The legs of an isosceles triangle are equal. In this problem, we're given the length of one leg: 3x-4. That means that the length of the other leg is also 3x-4. Now, the last side of the triangle is x ("base is x).

2(3x-4) + x = 76

6x-8+x=76

7x-8=76

7x=84

x=12

Let's check our answer.

3(12) - 4 =36-4 = 32

32 times 2 = 64 +12 =76

Correct!

Ronnie records the number of chirps per minute (x) that crickets make at different temperatures(Y ) in degree Fahrenheit. he determines that the association is linear and that the line of best fit is Y=1/6x+60.what is the interpretation of the slope and y intercept of this question?

Answers

Answer:

Step-by-step explanation:

Given

[tex]y = \frac{1}{6}x + 60[/tex]

Required

Interpret the slope and y intercept

The general form of an equation is:

[tex]y = mx + b[/tex]

Where

[tex]m=slope[/tex]

[tex]b = y\ intercept[/tex]

By comparison

[tex]m = \frac{1}{6}[/tex]

[tex]b = 60[/tex]

Interpretation:

Slope represents rate and y intercept represents the number of chirps at time 0.

So, the interpretations are:

Slope: The cricket chirps at a rate of [tex]\frac{1}{6}[/tex] chirps per minute

y intercept: The initial number of chirps is 60

The required coordinates of Amy's position are (1.00, 1.73).

Amys walk 2 miles 60° northeast from her house. Vector coordinates to be determined.

What is coordinate?

Coordinate is defined as the abscissa and ordinate of the x-axis and y-axis respectively.

Amy walk 2 miles on 60° northeast, from origin.

x coordinate = 2cos60
                      = 2 * 1/2
                      =  1
y coordinate = 2sin60
                     = 2*√3/2
                     =   1.73

Thus, the required coordinates of Amy's position are (1.00, 1.73).

If you’re having trouble with your nines times table use the finger trick. But it only works for 9x1-9-10 so hold up your hands in front of you and your palms facing towards you. Since you’re using 9x9 put your ninth finger down and the amount of fingers on your left would be the amount of tens so their would be 8 tens meaning 80 and the amount of fingers on the right side of the finger that is down would be the ones so there is one finger on the right. After that, you can just add them up. 80+1= 81 if you need another example just comment on this and say if you’re confused.:)

The sum of three consecutive even numbers is 228. What is the 3rd number?

Answers

Answer:

74 , 76 , 78

Step-by-step explanation:

Let the first of your number be x, As you are only looking at even integers, the next consecutive even integer would be x+2 and the consecutive even integer after that would be x+4. The sum of these three even integers results in 228 so we can say that:

[tex]First\ even\ number\ + Second\ even\ number\ + Third\ even\ number\ =228 \\\\x+(x+2)+(x+4)=228[/tex]

[tex]x+x+2+x+4=228\\3x+6=228\\3x=228-6\\3x=222\\x=222/3\\x=74\\[/tex]

so the first even number is 74 then the second consecutive even number is 76 then the third consecutive even number is 78

Kendra has an unlimited supply of unbreakable sticks of length 2, 4 and 6 inches. Using these sticks, how many non-congruent triangles can she make if each side is made with a whole stick

Answers

Answer:

Unlimited number of triangles.

Step-by-step explanation:

Unlimited number of triangles can be made because Kendra has unlimited supply of unbreakable sticks. If she has limited number of sticks suppose 90 sticks so she can be able to made 30 non-congruent triangles from these number of sticks so if the number is not known so we are unable to say about the number of triangles should be made from unlimited unbreakable sticks.
