The length of one side of a triangle is 3 feet less than twice the length of its second side. The third side is 2/3 of the sum of the lengths of the first 3 sides. Find the length of all three sides if the perimeter is 6.5

Answer:

x° + x° + 10° + x° + 15° + x° + 20° + x° + 25° + x° + 30°

= 6x° + (10 + 15 + 20 + 25 + 30)°

= 6x° + 100

0 = 6x + 100

6x = 100

X = 100/6

X = 16.66

Answer:

5 faces, 8 edges, 5 vertices

multiply 5.5 the width with 1.5 by 3 which gives you 24.75 inches feet long.

5.5 x 1.5 x 3=24.75 that's your answer.

Answer:297 cubic inches, other person is incorrect.




Step-by-step explanation:5.5 inches* 1.5inches * 3 feet
Convert 3 feet to inches and you have 36 inches. So now it becomes 5.5inches*1.5inches*36inches = 297 cubic inches

Hi there!

[tex]\huge\boxed{4 \text{ cm}^{2}}[/tex]

Find the area of the shaded area using the given dimensions:

The shaded area is divided up into two triangles, each with a base of 2 cm and a height of 2 cm. Use the following equation to solve for area:

A = 1/2(bh)

A = 1/2(2 · 2)

A = 1/2(4) = 2 cm²

There are two triangles, therefore:

2 × 2 = 4 cm²

Answer:

Hey do you know the answer to the question you wrote a while ago?

Step-by-step explanation:

(02.05)

Two similar triangles are shown on the coordinate grid:

A coordinate plane is shown. Triangle XYZ has vertices X at negative 5 comma negative 1, Y at negative 6 comma negative 2, and Z at negative 3 comma negative 2. Triangle X double-prime Y double-prime Z double-prime has vertices X double-prime at 10 comma negative 2, Y double-prime at 12 comma negative 4, and Z double-prime at 6 comma negative 4.

Which set of transformations has been performed on triangle XYZ to form triangle X′′Y′′Z′′?  

Do you?? :(

Answer:

Step-by-step explanation:

Your first step will be to set up the problem:

f(x) - g(x)

Next you will substitute in your values:

(2x + 1) - (x2 - 7)

The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:

2x + 1 - x2 + 7

Then combine your like terms:

2x - x2 + 8

Lastly put your expression in standard form (highest exponent to lowest)

-x2 + 2x + 8

Hope this helped!

[tex]\huge\underline\bold\blue{ƛƝƧƜЄƦ}[/tex]

(3x + 5)(3x - 5)

By using identity

(a + b)(a - b) = a² - b²

Answer:

8%

Step-by-step explanation:

For simple interest, we use the equation I = PRT, where I is the interest earned, P is the principal/amount invested, R is the rate as a decimal, not percentage, and T is the time in years.

For this problem, we have to use 0.5 for T, because 6 months is 1/2 a year.

20 = (500)(r)(0.5)

20 = 250r

r = 0.08 = 8%

Answer:

very easy just simplify and solve

Step-by-step

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Suppose x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]

Multiplying both sides by 100, we get

[tex]7x+16x+27x=15000[/tex]

[tex]50x=15000[/tex]

Dividing both sides by 50, we get

[tex]x=\dfrac{15000}{50}[/tex]

[tex]x=300[/tex]

So, the amount invested at 7% is [tex]300[/tex].

The amount invested at 8% is

[tex]2(300)=600[/tex]

The amount invested at 9% is

[tex]3(300)=900[/tex]

Hence, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

Answer:

x = 45

Step-by-step explanation:

x + 2x + x = 180

4x = 180

x = 45

Answer:

Since its a triangle, all the angles must add to 180. So x+x+2x=180. Solve for x and you got your answer.
