Answer:

28

Step-by-step explanation:

We can see that all the angles are inside of a triangle and the sum of the interior angle of the triangle is 180 degrees.

Knowing this, we know that the sum of all the angles present is 180 degrees.

1st angle can be seen as 90 degrees, 2nd angle is x+6 and the 3rd is 2x.

The sum can be written as ( 90 + x + 6 + 2x ) and this equals to 180 degrees.

90 + x + 6 + 2x = 180

96 + 3x = 180

( subtract 96 on both sides )

3x = 180 - 96

3x = 84

( divide by 3 on both sides )

x = 84 / 3

x = 28

Answer:

x = 28

Step-by-step explanation:

Consider the lower right triangle

The 2 given angles sum to 90° ( sum of angles in a triangle = 180° )

Hence

x + 6 + 2x = 90

3x + 6 = 90 ( subtract 6 from both sides )

3x = 84 ( divide both sides by 3 )

x = 28

Rotations, translations and reflections are transformations that preserve areas, so they always produce congruent figures.

So, the only way you have to produce a similar but not congruent figure is to use dilation with a scale different than 1.

Answer: [tex]\frac{x}{5}+9[/tex]

Step-by-step explanation:

Let be "x" the number mentioned in the given phrase.

"...the quotient of a number and five" indicates a division. In other words, the number "x" is divided by 5. This can represented as:

[tex]\frac{x}{5}[/tex]

Now,  "Nine more than the quotient of a number and five" indicates that you need to add 9 to the quotient of a number and five ( [tex]\frac{x}{5}[/tex]).

Knowing this, you can conclude that the translation of "Nine more than the quotient of a number and five" into  a math expression is:

[tex]\frac{x}{5}+9[/tex]

Final answer:

The word phrase 'nine more than the quotient of a number and five' translates to the math expression '(x/5) + 9', where 'x' represents the number.

Explanation:

To translate the word phrase 'nine more than the quotient of a number and five' into a math expression, we first identify the quotient of a number and five, which is denoted as ‘x ÷ 5’ or ‘x/5’ where x represents the number. Next, we address the phrase 'nine more than', which indicates that we need to add nine to that quotient. So, the phrase translates to the algebraic expression ‘(x/5) + 9’.

Therefore, as per the above explaination,  the correct answer is (x/5) + 9

Answer:

1)he maximum height your feet will be above the ground is 2.25

2)Will you be able to dunk the ball= No

Step-by-step explanation:

Given:

In order to dunk the basket ball, height needed to jump= 2.5 feet

The height that your feet need to be of the ground is given by the function h(t)= -16t^2+12t

1) the maximum height your feet will be above the ground=?

Given function of height,h(x)=-16t^2+12t

finding maximun of the above function

The maximum of any function written in form of ax^2+bx+c is given by

max= c - (b2 / 4a)

Putting values c=0, b=12 and a=16, we get

max= 0-(12^2/4(-16))

      = 144/64

      =2.25 feet

he maximum height your feet will be above the ground is 2.25 feet.

2)  Will you be able to dunk the ball=?

As the height needed to jump in the air to dunk the ball is 2.5 feet which is greater than the maximum height the feet will be above the ground i.e.

2.5>2.25

hence No you will not be able to dunk the ball !

The maximum height your feet will be above the ground is 2.25 feet. No, you will not be able to dunk the ball.

To find the maximum height your feet will be above the ground, we need to determine the vertex of the quadratic function h(t) = -16t^2 + 12t.

The vertex of a quadratic function of the form h(t) = at^2 + bt + c is given by the formula t = -b/2a. In this case, a = -16 and b = 12, so the vertex is t = -12/(2*(-16)) = 0.375 seconds.

Substituting this value back into the function h(t), we get h(0.375) = -16(0.375)^2 + 12(0.375) = 2.25 feet. Therefore, the maximum height your feet will be above the ground is 2.25 feet.

Since you need to jump 2.5 feet in the air to dunk the ball and the maximum height your feet will reach is only 2.25 feet, you will not be able to dunk the ball.

ANSWER

The hypotenuse is 14√2 units.

EXPLANATION

Let the hypotenuse be x, then we can use the Pythagoras Theorem to find the length of the hypotenuse.

We have from the question that, each leg of the 45-45-90 triangle measures 14 cm.

Then, the Pythagorean Theorem, gives:

[tex] {x}^{2} = {14}^{2} + {14}^{2} [/tex]

[tex] {x}^{2} = 2 \times {14}^{2} [/tex]

Take positive square root to obtain;

[tex]x = \sqrt{ {14}^{2} \times 2} [/tex]

This simplifies to

[tex]x = 14 \sqrt{2} [/tex]

The length of the hypotenuse of the 45-45-90 triangle is 19.796 cm.

In a 45-45-90 triangle, the two legs are congruent (they have the same length) and the length of the hypotenuse is equal to the length of the legs multiplied by the square root of 2.

Given that each leg of the triangle measures 14 cm, the length of the hypotenuse can be calculated as follows:

Length of hypotenuse = Length of leg × √2

Length of hypotenuse = 14 cm × √2

Using a calculator or approximating the square root of 2 to 1.414, we can find:

Length of hypotenuse ≈ 14 cm × 1.414

Length of hypotenuse ≈ 19.796 cm (rounded to three decimal places)

Therefore, the length of the hypotenuse of the 45-45-90 triangle is approximately 19.796 cm.

Answer is 1

Answer:

Any number divided by itself is 1.

Step-by-step explanation:

One of the nice parts about algebra is that -- if a number appears more than once -- you can make things a lot cleaner looking by throwing them in a variable. Let's let x = -2² . Our equation then becomes x ÷ x = 1, and it's much clearer here that, since we're dividing x by itself, the answer should clearly be one.

The ratios 4/6 and 8/12 are equivalent ratio of 2/3 which we obtain by multiplying or dividing both numerator and denominator by same number.

To find a ratio that is the same as 2/3, we can multiply or divide both the numerator and the denominator by the same non-zero number.

This will result in an equivalent ratio.

If we multiply both the numerator and denominator of 2/3 by 2, we get:

(2 × 2) / (3 × 2)

= 4/6

Therefore, the ratio 4/6 is the same as 2/3.

Similarly, if we multiply both the numerator and denominator of 2/3 by 2, we get:

8/12

So, the ratio 8/12 is also the same as 2/3.

Shorts $17

Step-by-step explanation:

Let:

T - shirts

S - shorts

We can make two equations out of this problem:

4T + 3S = $79

7T + 8S = $185

Through substitution we can solve for one of the unknowns. We make one equation to solve for an unknown

[tex]4T+3S=\$79\\\\3S = \$79-4T\\\\S=\dfrac{\$79-4T}{3}[/tex]

We use the formula of S and insert it into the other equation:

[tex]7T+8(\dfrac{\$79-4T}{3}) = \$185\\\\7T + \dfrac{\$632-32T}{3}=\$185\\\\\dfrac{\$632-32T}{3}=\$185-7T\\\\\$632-32T=3(\$185-7T)\\\\$632-32T=\$555 - 21T\\\\-32T+21T=\$555-\$632\\\\-11T=-\$77\\\\\dfrac{-11T}{11}=\dfrac{-\$77}{11}\\\\T = \$7[/tex]

Thus T-shirts are $7 each.

Now that we know T, we can use it to solve for the other unknown. You can use it on any of the formulas.

[tex]4T+3S=\$79\\\\4(\$7) + 3S = \$79\\\\\$28+3S =\$79\\\\3S=\$79-\$28\\\\3S=\$51\\\\S=\dfrac{\$51}{3}\\\\S = \$17[/tex]

The factors of 45 are 9 and 5

9 is a perfect square root, but 5 is not

Think of the problem like this

Step-by-step explanation:

Answer:

1. 40%

2. The theoretical probability is 3% greater than the experimental probability.

Step-by-step explanation:

We are informed that a number cube is rolled 20 times and the number 4 is rolled 8 times. The experimental probability of rolling a 4 is;

(the number of times a 4 was rolled)/(total number of rolls)

8/20 = 0.4

0.4*100 = 40%

The experimental probability of obtaining at least one tails, one or more tails, is represented in mathematical notation as;

P(HT or TH or TT)

The above events are mutually exclusive, thus;

P(HT or TH or TT) = P(HT) + P(TH) + P( TT)

                               = (22+34+16)/(28+22+34+16)  

                               = 0.72 = 72%

On the other hand, the theoretical probability of obtaining at least one tails,

P(HT or TH or TT) = 3/4

                              = 75%

This is because there is at least one tail in 3 out of 4 possible outcomes.

Therefore, it is true to say that the theoretical probability is 3% greater than the experimental probability.

Answer:

1. 40%

2. The theoretical probability is 3% greater than the experimental probability.

Step-by-step explanation:

1. Lets define experimental probability first.

Experimental probability is the probability of an event's occurrence when the experiment was conducted.

The number cube is rolled 20 times, so our sample space is 20.

And the number 4 came in result 8 times, so the the event space is 8.

So,

Experimental Probability = 8/20

=> 0.4

Converting into percentage will give:

=> 40%

So the first option is correct.

2. First we have to find the theoretical probability of getting at least one tail when two coins are tossed

The sample space is {HH, HT, TH, TT}

3 out of these 4 outcomes contain at least one tail

So the theoretical probability of getting at least one tail is: 3/4

=> 0.75 or 75%

Now for the experimental probability,

The total sample space is 28+22+34+16 = 100

The number of favorable outcomes are(Which contain at least one tail):

22+34+16 = 72

So, experimental probability of getting at least one tail = 72/100

=> 0.72 or 72%

We can see that the theoretical probability is 3% greater than the experimental probability. So second option is correct..

Answer:

1)center =(-2,3)

2) Vertices = (8,3) and (-12,3)

3) foci =(4,3) and (-8,3)

Step-by-step explanation:

As the general equation of ellipse with center at (h,k) is given by:

(x-h)^2/a^2 +(y-k)^2/b^2 = 1

where a=radius of the ellipse along the x-axis

b=radius of the ellipse along the y-axis

h, k= the x and y coordinates of the center of the ellipse.

Given equation of ellipse:

(x+2)^2/100 + (y-3)^2/64 = 1

1)

Finding center:

comparing with the general formula

h=-2 and k=3

Center of given ellipse is at (-2,3)

2)

Finding vertices:

comparing given equation of ellipse with the general formula:

a^2= 100 and b^2=64

then a = 10 and b=8

As a>b, it means the ellipse is parallel to x-axis

hence vertices along the x-axis are a = 10 units to either side of the center i.e (8,3) and (-12,3)

The co-vertices along the y-axis are b=8 units above and below the center i.e (-2,11) and (-2,-5)

3)

Finding Foci, c:

From equations of general ellipse we have a^2 - c^2=b^2

Putting values of a^2=100 and b^2=64 in above

100-c^2=64

c^2=100-64

     = 36

taking square root on both sides

c=6

foci of given ellipse is either side of the center (-2,3) that is (4,3) and (-8,3)!

You just need to factor a to get

[tex]a(1+2+3+4) = 10a[/tex]
