The length of the base of an isosceles triangle is x. The length of a leg is 3x - 6. The perimeter of the triangle is 58. Find x.

Answers

Answer 1

Answer:

x = 10

Step-by-step explanation:

Perimeter of a triangle = the sum of the three sided of the triangle.

In an isosceles triangle, there are two equal sides and  a base.

Perimeter = ( 3x - 6) + (3x - 6) + x

            58 = 7x - 12

            58 + 12 = 7x

                   70  = 7x

                    [tex]\frac{70}{7} = \frac{7x}{7}[/tex]

                    10 = x

The measure of the angle will be 141°. Then the correct option is B.

What is an angle?

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

A protractor is used on an angle one ray of the angle is 46 degrees and the other way is 95 degrees.

The diagram is shown below.

Then the measure of the angle will be given as,

⇒ 46° + 95°

⇒ 141°

The measure of the angle will be 141°.

Then the correct option is B.

Please help me. I'm struggling with my math

Answers

Answer:

a. (4, -3)

b. (-2.5, -4)

Step-by-step explanation:

a. 2x - 4y = 20

x = 4

step 1: plug in x value

2(4) - 4y = 20

8 - 4y = 20

Subtract 8 on both sides

-4y = 12

divide both sides by -4

y = -3

b. y = 6x + 11

2x - 3y = 7

step 1: plug in the y value

2x - 3(6x + 11) = 7

step 2: distribute

2x - 18x  - 33 = 7

add 33 from both sides and combine like terms

-16x = 40

divide both sides by -16

x = -2.5

Okay now you plug in the x value to solve for y

y = 6(-2.5) + 11

y =-4

On Monday, Anya read 11 pages of a book in 1 2 hour. On Tuesday, she read 18 pages in 3 4 hour. Did Anya's reading speed increase by more than 10% from Monday to Tuesday? Complete the justification for your answer.

Answers

Answer:

The way you should go about solving this really depends on how your teacher taught you...However, here's what I would recommend...

You know that 1/2 an hour is equal to 30 minutes, and 3/4 of an hour is equal to 45 minutes.

Using this you can  then solve for how many pages she read per minute by dividing the number of pages read by the number of minutes read:11 pages/ 30 minutes to give you Monday's reading speed,and18 pages/ 45 minutes to give you Tuesday's reading speed.

Next, to calculate a percentage increase you need to do the following:

1. Determine the difference between the speeds (this means you will subtract Monday's reading speed from Tuesday's reading speed.)

2. Next you take that number and divide it by Monday's reading speed.

3. Multiply that answer by 100 to get the percentage.

I'm not going to tell you the speeds, as you should try to attempt to solve it by yourself, and I'm sure you need to show your work. I will however tell you that you should find there was a 3.3% increase from Monday to Tuesday.

Create a shape with an area of 0.8 m2 and a perimeter close to 400 cm

Answers

The dimension of the shape is approximately 1.45 meters by 0.55 meters

Assume the shape is a rectangle, that has the following dimensions.

Length = x

Width = y

So, the area is:

Area = xy

The perimeter is

Perimeter = 2(x + y)

Substitute known values

[tex]\mathbf{xy = 0.8m^2}[/tex]

[tex]\mathbf{2(x+y) = 400cm}[/tex]

Express cm as m

[tex]\mathbf{2(x+y) = 4m}[/tex]

Divide through by 2

[tex]\mathbf{x+y = 2m}[/tex]

Make x the subject (ignore the units)

[tex]\mathbf{x= 2 - y}[/tex]

Substitute 2-y for x in [tex]\mathbf{xy = 0.8m^2}[/tex]

[tex]\mathbf{(2-y)y = 0.8}[/tex]

Open brackets

[tex]\mathbf{2y-y^2 = 0.8}[/tex]

Rewrite as:

[tex]\mathbf{y^2 - 2y + 0.8 = 0}[/tex]

Using a calculator, we have:

[tex]\mathbf{y \approx (0.55,1.45)}[/tex]

Recall that:

[tex]\mathbf{x= 2 - y}[/tex]

So, we have:

[tex]\mathbf{x \approx (2-0.55,2-1.45)}[/tex]

[tex]\mathbf{x \approx (1.45,0.55)}[/tex]

Hence, the dimension of the shape is approximately 1.45 meters by 0.55 meters
