Answer:

c

Step-by-step explanation:

x=0 and x= one half (1/2) is the solution of rational equation:

Option C is correct.

Step-by-step explanation:

We need to solve rational equation:  and identify extraneous solutions.

Solving:

Cross multiplying and solving:

So, values of x are x= 0 and x=1/2

Checking for extraneous solutions.

To check for extraneous solutions we will put value of x in the given rational equation and check if it satisfies the equation or not.

Putting x=0

Putting x= 1/2

Since both values satisfies the given equation so, there is no extraneous solutions.

Answer:

5x+12=5x-7

Step-by-step explanation:

If both x's on each are the same number, but with different constants, then the equation is unsolvable. If 5x+12=y, then 5x-7 can't also equal y because they are two different equations.

With all other equations, although some come out irrational, they are solvable and have a solution to them.

Answer:

93.7 miles

Step-by-step explanation:

This problem can be represented as a right angled triangle. The distance between the final point and the starting point is the hypotenuse.

We need to find the hypotenuse. We can use Pythagoras rule:

[tex]hyp^2 = opp^2 + adj^2[/tex]

where opp = opposite side to the angle considered

adj = adjacent side to the angle considered

This implies that:

[tex]x^2 = 60^2 + 72^2\\\\x^2 = 8784\\\\x = \sqrt{8784} \\\\x = 93.7 miles[/tex]

The car is 93.7 miles far from its starting point.

Answer:

17

Step-by-step explanation:

Let x be the first side

x+2 is the next side ( consecutive odd number)

x+4 is the third side ( consecutive odd number)

P = x + x+2 + x+4

45 = x + x+2 + x+4

Combine like terms

45 = 3x+6

Subtract 6 from each side

45-6 = 3x+6-6

39 = 3x

Divide by 3

39/3 = 3x/3

13 =x

The longest side is

x+4

13+4 = 17

The longest side is 17

The longest side is 16.

Let the consecutive sides be y, y+1, and y+2.

The perimeter of a triangle is gotten by adding all its sides. Therefore, the perimeter will be:

y + y+1 + y+2 = 45

Collect like terms

3y = 45 - 3

3y = 42

Divide both side by 3

3y/3 = 42/3

y = 14

Therefore, the longest side will be:

y + 2 = 14 + 2 = 16

The longest side is 16.

Answer:

d

Step-by-step explanation:

The equation of a line which passes through the origin is

y = mx ( where m is the slope )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (1, 4)

m = [tex]\frac{4-0}{1-0}[/tex] = 4 , thus

y = 4x → d

Answer:

D

Step-by-step explanation:

Please refer to picture attached.

The best method to deduce if the graph passes through the points mentioned, just substitute the values of x from the point into the equation to deduce if the y value is the same as the value in the point.

Answer:

The answer would be A. 55.

Step-by-step explanation:

For the 35% you would take your 200 and divide it by 2 and have two 100's. Since 35% is out of 100% you could take 35 from each 100 and add them together to get 70.

For the 3/8 you would divide and get .375 then you would multiply that by 200 which would give you 75 yellow tags. Then you would add 75 and 70 and get 145. Then subtract 145 from 200 to get 55. Therefore there would be 55 red tags.

The number of Jordan's tags that are red are; A: 55 tags

35% of the 200 tags are blue. Thus;

Number of blue tags = 35% * 200 = 70 tags

3/8 of the 200 name tags are yellow. Thus;

Number of yellow tags = 3/8 * 200 = 75 tags

The remaining tags are red. Thus;

Number of red tags = 200 - (75 + 70)

Number of red tags = 55 tags

Answer:

1012

Step-by-step explanation:

She eats 1012 because:

If she eats 45 in 2 minutes then she eats 22.5 in 1 minute.

This is because 45 ÷ 2 = 22.5

Sarah eats blueberries for 45 minutes so we multiply 22.5 by 45

22.5 × 45 = 1012.5

She ate 1012 full berries.

Answer:

Dante most likely asked the students if they should change the school mascot. This is a statistical question because the question can be answered by data that varies.

Step-by-step explanation:

You can see that the results for this question are either "yes" or "no". This means that Dante asked a question with a yes or no answer related to changing the mascot. This question was probably something along the lines of whether or not the mascot should be changed.

The definition of a statistical question is "a question that should have different answers". Therefore, this is a statistical question because the answers will be different from student to student.

Answer:

A.) 3

Step-by-step explanation:

Let's start with the numerator:

√36/√4

√36 = ?

We know that 36 is a perfect square, or the product of one number multiplied by itself.

6 x 6 = 36

So, √36 = 6

Let's look at the denominator:

√36/√4

√4 = ?

We know that 4 is also a perfect square.

2 x 2 = 4

So, √4 = 2

Now we have the numerator: 6

And the denominator: 2

Fraction: 6/2

If we simplify this fraction, we are left with 3 because 6 divided by 2 is 3.

Therefore, the first answer is correct.

Step-by-step explanation:

Chord PY is congruent to Chord NL of a circle with center 0. Option A is correct.

Given,
A circle with center o is shown with two chords equidistant from the center which is 3 units.

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²,
where h, k is the coordinate of the circle's center on the coordinate plane and r is the circle's radius.

Since the property of the circle describes that chords that are equidistant from the center of the circle are equal in length,

In the given question both the given chords are equidistant from the center of the circle i.e 3 units, so the Chord PY is congruent to Chord Nl.

Thus, Chord PY is congruent to Chord NL of the circle with center o. Option A is correct.

IS THIS HOW YOU DO IT

Answer: left 1 down 6

Answer:

The answer is B.

Step-by-step explanation:

When Elimination method is applied, you have to eliminate one of the variables from both equations. Firstly, both equations contain 4y so you can subtract it :

[tex]7x + 4y = 39 - - - (1)[/tex]

[tex]2x + 4y = 14 - - - (2)[/tex]

[tex](1) - (2)[/tex]

[tex]7x + 4y - 2x - 4y = 39 - 14[/tex]

[tex]5x = 25[/tex]

[tex]x = 25 \div 5[/tex]

[tex]x = 5[/tex]

Next, you have to substitute x = 5 to any equations. I will choose to put in (2) :

[tex]substitute \: x = 5 \: into \: (2)[/tex]

[tex]2(5) + 4y = 14[/tex]

[tex]10 + 4y = 14[/tex]

[tex]4y = 14 - 10[/tex]

[tex]4y = 4[/tex]

[tex]y = 4 \div 4[/tex]

[tex]y = 1[/tex]

Therefore, put your answer in coordinate form :

[tex]x = 5 \\ y = 1[/tex]

Answer:

The answer is 324π m².

Step-by-step explanation:

Given that the surface area of sphere formula is S.A = 4×π×r² where r is radius. The diameter of sphere is 18m so you have to divide it by 2 to find it's radius :

[tex]radius = diameter \div 2[/tex]

[tex]radius = 18 \div 2[/tex]

[tex]radius = 9m[/tex]

Then substitute into the formula :

[tex]s.a = 4 \times \pi \times {r}^{2} [/tex]

[tex]let \: r = 9[/tex]

[tex]s.a = 4 \times \pi \times {9}^{2} [/tex]

[tex]s.a = 4 \times \pi \times 81[/tex]

[tex]s.a = 324\pi {m}^{2} [/tex]

Answer:

The answer is 324π m².

Step-by-step explanation:

Given that the surface area of sphere formula is S.A = 4×π×r² where r is radius. The diameter of sphere is 18m so you have to divide it by 2 to find it's radius

No, 16i^2+8i+15

Step-by-step explanation:

No, she did not square it properly.

So in this case, a=3, and b=4i

(3+4i)^2

=9+6+8i+16i^2

=15+8i+16i^2

Answer:

HEXAGON:

Using the same methods as for hexagons to the right (I'll let you do the pictures)... 

To find the sum of the interior angles of a dodecagon, divide it up into triangles... There are ten triangles...  Because the sum of the angles of each triangle is 180 degrees...  We get

So, the sum of the interior angles of a dodecagon is 1800 degrees.

Regular Dodecagons:The properties of regular dodecagons:

All sides are the same length (congruent) and all interior angles are the same size (congruent).

To find the measure of the angles, we know that the sum of all the angles is 1800 degrees (from above)...  And there are twelve angles...

So, the measure of the interior angle of a regular dodecagon is 150 degrees.

The measure of the central angles of a regular dodecagon:

To find the measure of the central angle of a regular dodecagon, make a circle in the middle (I'll let you do the picture)...  A circle is 360 degrees around...  Divide that by twelve angles...

So, the measure of the central angle of a regular dodecagon is 30 degrees.
