[tex]x=180-(51+62)=180-113=\boxed{67}[/tex]

Answer:

x = 67

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180 to obtain x, that is

x = 180° - (62 + 51)° = 180° - 113° = 67°

Answer:

13cm, 7cm, 6cm

Step-by-step explanation:

To make a triangle you have to think about it in this way. The two smallest numbers should equal the largest number.

Answer:

13 cm, 7 cm, 6 cm

Step-by-step explanation:

The sum of the 2 shorter sides of the triangle has to be equal or longer than the longest side. In this case 7+6=13 which is equal.

Answer with Step-by-step explanation:

A candle is 4 inches tall and burns at the rate of 0.6 inch per hour.

i.e. after 1 hour height of candle=4-0.6 inches

After 2 hours height of candle=4-0.6-0.6 inches

after x hours height of candle=4-0.6x

Also,

If the height of the candle after x hours is 1.5 inches

⇒  4-0.6x=1.5

⇒ 0.6x=4-1.5

⇒ 0.6x=2.5

⇒ x=2.5/0.6

⇒ x=4.166

Hence, equation to represent the situation. is:

4-0.6x=1.5

and the expected number of hours in which the candle  melted to 1.5 inches is:

4.166 hours

After defining and solving the linear equation representing the candle's height over time, it is determined that it will take approximately 4.17 hours for the candle to burn down to 1.5 inches.

This is a problem about rates and linear equations in the subject of mathematics. The candle starts at 4 inches and burns at a rate of 0.6 inch per hour, which decreases the height of the candle. So, the equation would be: height = starting height - (burn rate)x(time), or H = 4 - 0.6x.

From the problem we know, that the height of the candle after x hours is 1.5 inches. So, we substitute H with 1.5: 1.5 = 4 - 0.6x.

To solve for x, first we can subtract 4 from both sides: -2.5 = -0.6x. Then, divide both sides by -0.6 to isolate x. So, x = -2.5/-0.6 which simplifies to approximately 4.17 hours. So, it will take around 4.17 hours for the candle to burn down to 1.5 inches.

Answer:

A

Step-by-step explanation:

This one is best done by doing a pre factor.

140 = 14 * 10 Now all you need do is factor those two numbers.

140 = 7*2 * 5 * 2

Rearranging this you get 2 * 2 * 5 *7

A

Final answer:

The prime factorization of 140 is found by dividing it by the prime numbers 2, 2, 5, and 7 in sequence, resulting in 2 x 2 x 5 x 7, which corresponds to option A.

Explanation:

The prime factorization of a number is the expression of the number as a product of its prime factors. To find the prime factorization of 140, we can use a factor tree or continuously divide by prime numbers. Beginning with the smallest prime number, 2, we divide 140 by 2 to get 70. Then, we divide 70 by 2 again to get 35. After that, we divide 35 by its smallest prime factor, which is 5, to get 7. Since 7 is already a prime number, we have completed the factorization. So, the prime factorization of 140 is:

2 x 2 x 5 x 7

Therefore, the correct answer is A.2 x 2 x 5 x 7.

The correct option is C.

Probability of selecting all boys from 8 boys and 6 girls for a 4-person committee is 10/143.

To find the probability that the committee consists of all boys, we need to calculate the probability of selecting 4 boys out of 8 boys and no girls out of 6 girls.

The total number of ways to choose a 4-person committee from 14 students (8 boys and 6 girls) is given by the combination formula:

[tex]\[ \text{Total number of ways} = \binom{14}{4} \][/tex]

The number of ways to choose 4 boys out of 8 is given by:

[tex]\[ \binom{8}{4} \][/tex]

And since we don't choose any gi-rls, the number of ways to choose 0 girls out of 6 is simply 1.

So, the probability of selecting all boys is:

[tex]\[ \text{Probability} = \frac{\binom{8}{4} \times \binom{6}{0}}{\binom{14}{4}} \][/tex]

Let's calculate this:

[tex]\[ \text{Probability} = \frac{\binom{8}{4} \times \binom{6}{0}}{\binom{14}{4}} = \frac{\frac{8!}{4!(8-4)!} \times \frac{6!}{0!(6-0)!}}{\frac{14!}{4!(14-4)!}} \][/tex]

[tex]\[ = \frac{\frac{8!}{4!4!} \times 1}{\frac{14!}{4!10!}} \][/tex]

[tex]\[ = \frac{\frac{8 \times 7 \times 6 \times 5}{4 \times 3 \times 2 \times 1}}{\frac{14 \times 13 \times 12 \times 11}{4 \times 3 \times 2 \times 1}} \][/tex]

[tex]\[ = \frac{70}{1001} \][/tex]

[tex]\[ = \frac{10}{143} \][/tex]

So, the correct answer is option C: [tex]\( \frac{10}{143} \)[/tex].

The complete question is here:

A four-person committee is chosen from a group of eight boys and six girls.. If students are chosen at random, what is the probability that the committee consists of all boys?

[tex]16a^2 - 4a + 4a - 1=(4a-1)(4a+1)[/tex]

Step-by-step explanation:

Simplify the expression

[tex]16a^2 - 4a + 4a - 1\\\\16a^2- 1[/tex]

remember that 4 ^ 2 = 16

Therefore

[tex]16a^2- 1= 4^2a^2 -1[/tex]

Remember that

[tex](4a) ^ 2 = 4 ^ 2a ^ 2[/tex]

[tex]4^2a^2 -1=(4a)^2 -1[/tex]

As [tex]1 ^ 2 = 1[/tex] then

[tex](4a)^2 -1= (4a)^2 -1^2[/tex]

Remember that [tex]c ^ 2 -b ^ 2 = (c + b) (c-b)[/tex]

In this case [tex]c = 4a[/tex] and [tex]b = 1[/tex]

Finally

Answer: 16/25

4/10 divided by 5/8 = ?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal or inverse of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes -

4/10 x 8/5 = ?

For fraction multiplication, multiply the numerators and then multiply the denominators to get -

Numerators: 4 x 8 = 32

Denominators: 10 x 5 = 50

Fraction: 32/50

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 32 and 50. The GCF (Greatest Common Factor) would be 2.

Numerator: 32 / 2 = 16

Denominator: 50 / 2 = 25

Fraction: 16/25

4/10 divided by 5/8 = ?

Cross multiply -

Numerator x Denominator: 4 x 8 = 32

Denominator x Numerator: 10 x 5 = 50

Fraction: 32/50

Reduce by dividing both the numerator and denominator by the Greatest Common Factor, which is 2.

Numerator: 32 / 2 = 16

Denominator: 50 / 2 = 25

Fraction: 16/25

Answer:

Step-by-step explanation:

The formula of an area of a square with side z:

A = z²

We have z = 3/2. Substitute:

A = (3/2)² = (3/2)(3/2) = 9/4

[tex]\bf \qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby \begin{array}{llll} k=constant\ of\\ \qquad variation \end{array} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ (-3,2)~~ \begin{cases} x=-3\\ y=2 \end{cases}\implies 2=k(-3)\implies -\cfrac{2}{3}=k[/tex]

To find the constant of variation k in the direct variation y = kx for the point (–3, 2), we substitute the point into the equation.

We get k = 2 / (–3), resulting in k = –rac{2}{3}.

The constant of variation, k, in the direct variation equation y = kx can be found using the coordinates of a given point that lies on the line represented by this equation.

Given a point (–3, 2), we can substitute these values into the equation to find k:

y = kx

2 = k(–3)

To isolate k, we divide both sides of the equation by (–3):

k = 2 / (–3)
k = –rac{2}{3}

Answer:

Vertex;

(2, -8)

The intercepts;

x-intercepts: (-2, 0) and (6, 0)

y-intercepts: (0, -6)

The axis of symmetry;

No axis of symmetry. X = 2 is a line of symmetry of the parabola

The sign of the lead coefficient;

Positive

Step-by-step explanation:

The graph shown in the attachment belongs to the parabola group of conic sections. The vertex of a parabola refers to the point where the parabola changes direction or also the lowest or the highest point on its graph. The graph is moving downwards from x = -4 to x = 2 and then starts moving upwards from x = 2 to x = 8. The vertex is thus located at the point x = 2. At this point, the y value is -8. Thus the vertex is located at (2, -8). This is the lowest point on the graph.

The intercepts refers to the points where the graph of a function crosses or cuts either the x or the y axes.

The parabola crosses the x-axis at two points;

x = -2 and x = 6

At these points the value of y is usually 0. The x-intercepts are thus;

(-2, 0) and (6, 0)

The parabola crosses the y-axis at the point where y = -6 and the corresponding x value is 0. The y-intercept is thus;

(0, -6)

Neither the x-axis nor the y-axis is an axis of symmetry of the parabola since neither of the axis divides the parabola into two identical portions. Nevertheless, the vertical line x = 2 passing through the vertex divides the parabola into two identical portions such that the left portion is a mirror image of the right portion. We can thus conclude that the vertical line x = 2 is a line of symmetry of the parabola.

The sign of the lead coefficient of a parabola determine whether the parabola opens upward or downward;

If the sign of the lead coefficient is positive, the parabola opens upward. If the sign of the lead coefficient is negative, the parabola opens downward.

The parabola in the attachment opens upward and thus the sign of its lead coefficient is positive.

It’s > because when you square root 18 it’s 4.24264069

Answer:

The answer would be C, Greater Than, >.

Step-by-step explanation:

In this question, it is asked if 5 is equal to, less than or greater than the square root of 18. So we first need to find out the value of square root 18. We can do it manually or with a scientific calculator. If we do it with a calculator, we would come to know that the answer of square root 18 is 4. 24264068. Now we would compare it with 5. We will have to see if 5 is equal to, less than or greater than this value of square root of 18. So it is clear from the above answer of square root 18, that it is less than 5.

So the answer is C, that shows that 5 is greater than square root of 18, i-e 4.24264068.

Formula for area is:

A = pi*r^2

r = 28

so...

A = 3.14 * 28^2

A = 3.14 * 784

A = 2461.76 cm^2

Formula for circumference is:

C = 2*pi*r

r = 28

so...

C = 2*3.14* 28

C = 6.28*28

C = 175.84 cm

ANSWER

[tex]x = - 3 \: \: or \: \: x = 3[/tex]

The degree is two so it must have more than one solution.

EXPLANATION

The given equation is

[tex] {x}^{2} = 9[/tex]

Let us use the square root method to solve this equation.

Since the degree of x is two, the fundamental theorem of algebra says it must have 2 roots.

We take square root to obtain,

[tex]x = \pm \sqrt{9} [/tex]

[tex]x = \pm3[/tex]

Split the plus or minus sign to obtain,

[tex]x = - 3 \: \: or \: \: x = 3[/tex]

The solutions to the equation x² = 9 are x = 3 and x = -3. Because squares of both positive and negative numbers give the same result, quadratic equations usually have two solutions.

The solutions to the equation x² = 9 are x = 3 and x = -3. This is because square roots can be both positive and negative. When you square a positive number and a negative number, the result is the same. Hence, the equation x² = 9 could come from squaring either 3 or -3, which implies that x can be either 3 or -3. Therefore, quadratic functions or second-order polynomials, like this equation, usually have two solutions.
