Simplifying

3.2 = 2y

Solving

3.2 = 2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.

3.2 + -2y = 2y + -2y

Combine like terms: 2y + -2y = 0

3.2 + -2y = 0

Add '-3.2' to each side of the equation.

3.2 + -3.2 + -2y = 0 + -3.2

Combine like terms: 3.2 + -3.2 = 0.0

0.0 + -2y = 0 + -3.2

-2y = 0 + -3.2

Combine like terms: 0 + -3.2 = -3.2

-2y = -3.2

Divide each side by '-2'.

y = 1.6

Simplifying

y = 1.6

Two possible values for the length of the third side of a right angle triangle are 6 and [tex]\sqrt{164}[/tex].

" Right angle triangle is a triangle whose one of the interior angle is of 90°."

Formula used

Pythagoras theorem,

(Hypotenuse)² = (Opposite side)² + (adjacent side)²

According to the question,

Two sides of a right triangle measure 10 m and 8 m

Here it is not mentioned 10m and 8m representing which side , that's why this is not enough information to be sure of the length of the third side.

Two possibilities

If Hypotenuse = 10m

Length of one of the side of the right triangle  = 8m

Measure of other side  'x' equals to

[tex](10)^{2} = 8^{2} + x^{2}[/tex]

⇒[tex]x^{2} = 100 -64[/tex]

⇒[tex]x^{2} =36[/tex]

⇒[tex]x=6[/tex]

If Hypotenuse is not given then,

(Hypotenuse)² = [tex]10^{2} +8^{2}[/tex]

⇒(Hypotenuse)² = [tex]100 + 64[/tex]

⇒ Hypotenuse = [tex]\sqrt{164}[/tex]

Hence, two possible values for the length of the third side of a right angle triangle are 6 and [tex]\sqrt{164}[/tex].

Final answer:

Without knowing which of the two given sides is the hypotenuse in a right triangle, we cannot definitively calculate the length of the third side. It could be greater or less than 10.3 m depending on whether the 10 m side is the hypotenuse or one of the legs.

Explanation:

If two sides of a right triangle measure 10 m and 8 m, it is not enough information to be sure of the length of the third side. The reason is that without knowing which of the sides is the hypotenuse, or whether the given sides are the two legs or one leg and the hypotenuse, we cannot use the Pythagorean Theorem to find the exact length of the third side.

If the 10 m side is the hypotenuse, the other side (of length 8 m) would be a leg, and we could find the length of the remaining leg using the equation a² + b² = c², where c is the hypotenuse and a and b are the other two sides. Thus, the length of the third side would be less than 10.3 m.

However, if the side that measures 10 m is not the hypotenuse, then the remaining side would have to be longer than 10 m to satisfy the Pythagorean Theorem. The length of the third side would be greater than 10.3 m in this case.

Without additional information, we cannot commit to a single value for the third side and must acknowledge that both possibilities exist.

Answer:

256

Step-by-step explanation:

First, let's see the height of the box (8 inches) is long enough for one straw (7 inches and 3/4) but not enough for 2... so there could be only one layer.

Now the box is a prism with a square base (6 inches each side).

How many straws can we fit on one side?  We have to divide the width of the box by the width of a straw.  

[tex]row = \frac{6}{3/8} = \frac{48}{3} = 16[/tex]

We can fit 16 straw per 6-side side of the box... Since the box is 6x6 inches, we can then fit 16 x 16 straws in it... 256 total.

Step-by-step explanation:

Hello! :)

All angles in triangles must equal 180* degrees. So there is the 90 degrees at the meter Q and you add: 43+90=133* degrees. Remember, to make 180 so you do 180-133=47* degrees. I didn’t get any answer choices but if there are, choose the closest one to 47* degrees.

Hope this helped and I hope I answered in time!

Good luck!

~ Destiny ^_^

Answer:

The value of x = 47°

Step-by-step explanation:

From the figure we can see that a circle with center O.

PQ is a tangent to the circle fro point P.

m<P = 43°

Therefore <Q = 90°

To find the value of x

From the given triangle we can write,

x + m<Q + m<P = 180

x = 180 - (m<Q + m<P)

 = 180 - (90 + 43)

 = 180 - 133 = 47°

Therefore the value of x = 47°

The number of students with white shirts on is 19.

The answer is 19 because you do 50 times 38 and get 1900 and divide it by a 100 and get 19.

ok well i forget how to find the area of a trapezoid but you can solve it by breaking it down into a rectangle and two triangles

so for the rectangle multiply 7 by 4 to get 28

for the triangle you have to subtract 7 from ten to get 3 this is the length of the base. then you multiply 4 by 3 by 0.5 to get 6

now you have two triangles so multiply 6 by 2 to get 12

now add it all up to get 28+12=40

ummmmmmmmmmmmmmmm so this isn't an answer choice

i looked up the trapezoid formula and it is [tex]A=\frac{a+b}{2} h[/tex]

so if you fill in the blanks A=((7+10)/2)4

so A=(17/2)4

A=8.5*4

A=34

so the actual answer is 34 feet

but i see how you got 40

Answer:

(x+8)^2 - 67

Step-by-step explanation:

1) Rearrange the quadratic into the standard format: ax^2 + bx + c

In this case you rearrange it to x^2 + 16x - 3

2) Write out the initial bracket: (x + b/2)^2    -    Just divide the value of b (which in this case is 16) by 2 (which in this case gives you 8)

3) Multiply out the brackets and compare to the original to find what you need to add or subtract to complete the square

In this case you do (x+8)^2 which gives you x^2 + 16x +64

You compare this to the original: x^2 + 16x - 3

4) Add or Subtract the adjusting number to make it match the original

In this case you need to subtract 67 from x^2 + 16x +64 (which is the same as (x+8)^2) in order to make it match the original x^2 + 16x - 3

64 - 67 = -3

For this case we must solve the following inequality, finding the values for the variable "t":

[tex]t + 18 <43[/tex]

We subtract 18 from both sides of the inequality:

[tex]t + 18-18 <43-18\\t <25[/tex]

Thus, the variable "t" is defined for all strict lower values than 25.

Answer:

[tex]t <25[/tex]

Answer:

There is no solution to the given problem [tex]|x|=-2[/tex].

Step-by-step explanation:

Given equation is [tex]|x|=-2[/tex].

Now we need to determine if there is solution to this equation or not.

We know that [tex]|x|[/tex] represents absolute value function.

By definition of absolute value function, we know  that output of [tex]|x|[/tex] must always be positive.

But in given equation [tex]|x|=-2[/tex], we have output -2 which is negative.

That is not possible.

Hence there is no solution to the given problem [tex]|x|=-2[/tex].

To factorise the quadratic

Consider the factors of the constant term (- 21) which sum to give the coefficient of the x- term (- 4)

The factors are - 7 and + 3, since

- 7 × 3 = - 21 and - 7 + 3 = - 4, thus

(x - 7)(x + 3) = 0 ← in factored form

Answer:

Function represents decay.

[tex]V(t)=3000(0.70)^t[/tex]

Step-by-step explanation:

Given that the value of a $3000 computer decreases about 30% each year. Now we need to write a function for the computers value V(t). then determine if the function represent growth or decay.

It clearly says that value decreases so that means function represents decay.

For decay we use formula:

[tex]A=P(1-r)^t[/tex]

where P=initial value = $3000,

r= rate of decrease =30% = 0.30

t= number of years

A=V(t) = future value

so the required function is [tex]V(t)=3000(1-0.30)^t[/tex]

or [tex]V(t)=3000(0.70)^t[/tex]

The equivalent expressions are

3x + 5x and 8x

3(x + 4) and 3x + 12

a + b + a and 2a + b

What are equivalent expressions?

Equaivelnt expressions are expressions that the terms are equal. That is to say rearranging the terms will result to the term to be compared with it.

In this case the expressions are said to be equaivalent

Examining the expressions we can see that

3x + 5x = 8x

3(x + 4) = 3x + 12

a + b + a = 2a + b

Answer:

C 3/14

Step-by-step explanation:

There are a total of 8 checkers

P (black) = black/total

               = 2/8 = 1/4

Then we keep the checker, so there are only 7 checkers in the bag, 6 red and 1 black

P ( red) = red/total

           = 6/7

P (black, red) = 1/4 * 6/7
