does anyone know what 2/3 x= 8. So the question is what does x equal too

Answer:

ONE

Step-by-step explanation:

Only one.  Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.

Answer:  ONE

The required, an obtuse triangle is a triangle that has one angle measuring more than 90 degrees. By definition, an obtuse triangle has exactly one obtuse angle.

An obtuse triangle, by definition, contains one obtuse angle, which is an angle greater than 90 degrees but less than 180 degrees. The obtuse angle is the largest angle in an obtuse triangle, while the other two angles are acute angles (less than 90 degrees).

Since there is only one angle in an obtuse triangle that qualifies as an obtuse angle, we can conclude that there is exactly one obtuse angle in an obtuse triangle. The remaining two angles are acute angles.

It's important to note that the sum of the angles in any triangle is always 180 degrees. In the case of an obtuse triangle, the obtuse angle occupies a portion of that sum greater than 90 degrees, leaving the remaining acute angles to share the remaining portion of the 180-degree total.

The possible length for the third side of a triangle with two sides of length 5 must be greater than 0 and less than 10, as determined by the Triangle Inequality Theorem.

The student is asking about a possible third side of a triangle with two sides of length 5. To answer this, we will apply the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, any third side length must be less than 10 (5 + 5) but also greater than 0, because if it were 10 or more it wouldn't form a triangle but a straight line. However, since the smallest possible non-zero length a side can have is just above 0, we can say the third side must be greater than 0 and less than 10.

Answer:

6.28 feet

Step-by-step explanation:

1.) Find the radius.

The area is given, and the formula for area of a circle is A = [tex]\pi r^{2}[/tex]  Let's substitute.

3.14 = [tex]\pi r^{2}[/tex]

Divide by pi on both sides

1 = [tex]r^{2}[/tex]

Find the square root of r

1 = r

The radius is 1.

2.) Find the circumference.

C = [tex]2\pi r[/tex]

C = [tex]2\pi (1)[/tex]

Multiply 2 and 1

C = [tex]2\pi[/tex]

C ≈ 6.28

The circumference is approximately 6.28 feet.

Final answer:

To find the circumference of a circular serving tray with an area of 3.14 square feet, one must first calculate the radius using the area formula and then apply the circumference formula 2πr, yielding a circumference of 6.28 feet when rounded to the nearest hundredth.

Explanation:

In order to find the circumference of Isaac's circular serving tray given its area, we need to apply the formula for the area of a circle, which is A =
^2. Since the area was provided as 3.14 square feet, and using 3.14 as an approximation for
, we can set up the equation as 3.14 = 3.14r^2. This allows us to solve for the radius(r).

First, divide both sides by 3.14 to isolate r^2: r^2 = 3.14 / 3.14 = 1. Then take the square root of both sides to get the radius: r =
1 = 1 foot. Now that we have the radius, we can calculate the circumference using the formula C = 2
, substituting 3.14 for
, and the radius we just found: C = 2 * 3.14 * 1 = 6.28 feet.

After following these steps, we determine that the circumference of the serving tray is 6.28 feet. Rounded to the nearest hundredth, the circumference is 6.28 feet.

A is a simple addition problem.

C shows the associative property

D shows the commutative and associative property.

B shows that an expanded value is the same as something multiplied by something else in parentheses. Therefore, the answer is B.

I hope this helps!

Answer:

see explanation

Step-by-step explanation:

A

Given

(x² + 3)² + 21 = 10x² + 30 ← factor out 10 from each term on the right side

(x² + 3)² + 21 = 10(x² + 3) ← subtract 10(x² + 3) from both sides

(x² + 3)² - 10(x² + 3) + 21 = 0

Substituting u = x² + 3 into the equation gives

u² - 10u + 21 = 0 → D

---------------------------------------------

B

Using u² - 10u + 21 = 0 to solve the equation

Consider the factors of the constant term (+ 21) which sum to give the coefficient of the u- term (- 10)

The factors are - 3 and - 7, since

- 3 × - 7 = 21 and - 3 - 7 = - 10, thus

(u - 3)(u - 7) = 0

Equate each factor to zero and solve for u

u - 3 = 0 ⇒ u = 3

u - 7 = 0 ⇒ u = 7

We now have to use the substitution to convert the solutions into terms of x, that is

x² + 3 = 3 ( subtract 3 from both sides )

x² = 0 ⇒ x = 0 → D

x² + 3 = 7 ( subtract 3 from both sides )

x² = 4 ( take the square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2

Thus x = - 2 → C

x = 2 → E

Answer:

A number line going from 50 to 60. A solid circle is at 54. Everything to the right of the circle is shaded.

Step-by-step explanation:

we have the inequality

[tex]11\leq y-43[/tex]

solve for y

Adds 43 both sides

[tex]11+43\leq y[/tex]

[tex]54\leq y[/tex]

Rewrite

[tex]y\geq 54[/tex]

In a number line the solution is the shaded area at right of y=54 (closed circle)

therefore

A number line going from 50 to 60. A solid circle is at 54. Everything to the right of the circle is shaded.

The measure of ∠1 is 95°

Solution:

Given a || b.

m∠6 = 85° and m∠3 = 2x°

∠6 and ∠3 are co-interior angles.

Co-interior angles add up to 180°.

⇒ m∠6 + m∠3 = 180°

⇒ 85° + 2x° = 180°

Subtract 85° from both sides.

⇒ 2x° = 95°

⇒ m∠3 = 95°

If two lines cut each other, then vertically opposite angles are congruent.

⇒ m∠1 = m∠3

⇒ m∠1 = 95°

Hence the measure of ∠1 is 95°.

Answer: 75 boys

Step-by-step explanation: Our first step in this problem is to write down the unit ratio that is involved. In this case, it's boys/girls.

Next, we set up our proportion.

We know that there are 5 boys for every 6 girls.

So we have 5/6 and we're asked how many boys are at the dance if 90 girls are at the dance.

So we have [tex]\frac{5}{6} = \frac{x}{90}[/tex].

Notice that the 99 girls must go on the bottom of the second ratio because our unit ratio tells us that we put boys/girls.

Solving from here, we use the means-extremes property.

The product of the extremes,

(90)(5) equals the product of the means, (6)(x).

So we have (90)(5) or 450 equals (6)(x) or 6x.

So we have 450 = 6x and dividing both sides by 6, 75 = x.

So 75 boys are at the winter dance.

Answer:

x = [tex]\sqrt{13}[/tex]

Step-by-step explanation:

The line from the vertex to the base is a perpendicular bisector and divides the triangle into 2 right triangles.

Consider the right triangle on the left with base 2

Using Pythagoras' identity

The square on the hypotenuse (x) is equal to the sum of the squares on the other 2 sides, that is

x² = 2² + 3² = 4 + 9 = 13 ( take the square root of both sides )

x = [tex]\sqrt{13}[/tex]

Step-by-step explanation:

Answer:

B. 3 ÷ 1/4 = 12

This is the correct division problem because the result is 12 and we're calculating how many fourths are in 3 wholes.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of circles = 3

Number of divisions of every circle = 4

2. Which of the following division problems describes Melinda's work?

A. 4 ÷ 3 = 4/3

It's incorrect because the total number of fourths in 3 circles is 12.

B. 3 ÷ 1/4 = 12

This is the correct division problem because the result is 12 and we're calculating how many fourths are in 3 wholes.

C. 4 ÷ 1/3 = 12

It's incorrect because the question is to determine how many fourths are in 3 wholes, not how many thirds are in 4 wholes.

D. 3 ÷ 4 = 3/4

It's incorrect because the total number of fourths in 3 circles is 12.

Solution:

Given that,

[tex]\text{ slope of line } =\frac{3}{4}[/tex]

A different line passes through the points (6, 3) & (-1, 5)

Find the slope of this line

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

From given,

[tex](x_1, y_1) = (6, 3)\\\\(x_2, y_2) = (-1, 5)[/tex]

Substituting we get,

[tex]m = \frac{5-3}{-1-6}\\\\m = \frac{2}{-7}[/tex]

For two lines are parallel, then their slopes must be equal

But here,

[tex]\frac{3}{4} \neq \frac{-2}{7}[/tex]

Therefore, They are not parallel because their slopes are not equal

Answer:

70 days

Step-by-step explanation:

we  know that

A fort had provisions for 175 men for 70 days.

After 10 days a fort had provisions for 175 men for (70-10)=60 days

but

25 men left the fort

so

The remaining men are 175-25=150 men

Let

x ----> how long the provision will last

we know that

The equation that represent this problem is an inverse variation

[tex]175(60)=150(x)[/tex]

as the number of men decreases the number of days increases

solve for x

[tex]x=175(60)/150=70\ days[/tex]

using proportion

[tex]\frac{175}{60}=\frac{150}{x}\\\\x=150(60)/175\\\\x=70\ days[/tex]
