Answer:

∠ B = 54°

Step-by-step explanation:

Supplementary angles sum to 180°.

Sum A and B  and equate to 180, that is

7x + 14 + 5x - 26 = 180, that is

12x - 12 = 180 ( add 12 to both sides )

12x = 192 ( divide both sides by 12 )

x = 16

Thus

∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°

Answer:

5/6

Step-by-step explanation:

To simplify this fraction, we need to find the GCF (greatest common factor) of the numerator and denominator. In this case, the GCF of 55 and 66 is 11. Now, all we have to do is divide both the numerator and denominator by the GCF. The numerator will become 55 / 11 = 5 and the denominator will become 66 / 11 = 6 so the simplified fraction is 5 / 6.

Answer:

14. H. 110°

15. D. <8

Step-by-step explanation:

14. Given that line AD and line EG are parallel as shown above, m<3 and m<4 are linear pairs and are supplementary. That is, m<3 + m<4 = 180°.

If m<3 = 70°, therefore, m<4 = 180° - 70°

m<4 = 110°

15. <3 corresponds with <8. Corresponding angles are congruent. Therefore, <3 = <8.

Answer:

2x − 5

Step-by-step explanation:

To solve, divide the numerator by the denominator.  The result (not including the remainder) will be the equation of the slant asymptote.

We can tell the first term of the quotient will be 2x, so the answer will be either 2x − 5 or 2x − 17/3.

The easiest method here is to simply multiply these by denominator.

(3x² − 1) (2x − 5) = 6x³ − 15x² − 2x + 5

(3x² − 1) (2x − 17/3) = 6x³ − 17x² − 2x + 17/3

So the answer must be 2x − 5.

Alternatively, you can use long division.

Answer:

2x-5

Step-by-step explanation:

f(x)=(6x^3−15x^2+x−4 )/(3x^2−1)

To find the slant asymptote,divide the numerator by the denominator

       2x   +(-15x^2+3x-4)/ (3x^2-1)  

    -5   +   (3x-9)/(3x^2-1)

The divisor is (2x-5) and the remainder is ( 3x-9)

Answer:

False

Step-by-step explanation:

|x+y| = |x| + |y|

To show this is false, all we have to do is find one example where it is false

Let x = -1 and y = 4

|-1+4| = |-1| + |4|

|3| = |1| + |4|

3 = 5

This is false so we have a set of integers where the statement is not true

Answer:

[tex]Probability = \frac{845}{5832}[/tex]

Step-by-step explanation:

Given

Two standard dice

Required

Probability that the outcome will be greater than 8 for the first time on the third roll

First, we need to list out the sample space of both dice

[tex]S_1 = \{1,2,3,4,5,6\}[/tex]

[tex]S_2 = \{1,2,3,4,5,6\}[/tex]

Next, is to list out the sample when outcome of both dice are added together[tex]S = \{2,3,4,5,6,7,3,4,5,6,7,8,4,5,6,7,8,9,5,6,7,8,9,10,6,7,8,9,10,11,7,8,9,10,11,12\}[/tex]

Next, is to get the probability that an outcome will be greater than 8

Represent this with P(E)

[tex]P(E) = \frac{Number\ of\ outcomes\ greater\ than\ 8}{Total}[/tex]

[tex]P(E) = \frac{10}{36}[/tex]

[tex]P(E) = \frac{5}{18}[/tex]

Next, is to get the probability that an outcome will noy be greater than 8

Represent this with P(E')

[tex]P(E) + P(E') = 1[/tex]

[tex]P(E') = 1 - P(E)[/tex]

[tex]P(E') = 1 - \frac{5}{18}[/tex]

[tex]P(E') = \frac{18 - 5}{18}[/tex]

[tex]P(E') = \frac{13}{18}[/tex]

Now, we can calculate the required probability;

Probability of a number greater than 8 first on the third attempt is:

Probability of outcome not greater than 8 on the first attempt * Probability of outcome not greater than 8 on the second attempt * Probability of outcome greater than 8 on the third attempt

Mathematically;

[tex]Probability = P(E') * P(E') * P(E)[/tex]

Substitute values for P(E) and P(E')

[tex]Probability = \frac{13}{18} * \frac{13}{18} * \frac{5}{18}[/tex]

[tex]Probability = \frac{13 * 13 * 5}{18 * 18 * 18}[/tex]

[tex]Probability = \frac{845}{5832}[/tex]

Answer:

Answer: so the answer is 80 miles per 0.8 Step-by-step explanation: consistence

Answer:

Distance between the two check point (C and D) is 4920 ft.

Step-by-step explanation:

From the question given above, we obtained the following information:

X is 6000 ft from C (1st check point)

D (2nd check point) is the midpoint point between C and Y ( the end of the race)

Total race = 3 miles

1 mile = 5280 ft

Next, we shall express the total race in feet (ft).

This is illustrated below:

1 mile = 5280 ft

Therefore,

3 miles = 3 × 5280 = 15840 ft

Next, we shall determine the distance between the 1st check point (C) and the end of the race (Y)

This can be obtained as follow:

Total distance = 15840 ft

Distance between X and C = 6000 ft

Distance between C and Y =?

Distance between C and Y = (Total distance) – (Distance between X and C)

Distance between C and Y = 15840 – 6000

Distance between C and Y = 9840 ft

Finally, we shall determine the distance between the two check point (C and D) as follow:

Since D is midpoint between C and Y, therefore, we shall we shall divide the distance between C and Y by 2 in order to obtain the distance between the two check point (C and D).

This is illustrated below:

Distance between C and Y = 9840 ft

Distance between the two check point (C and D) = 9840/2 = 4920 ft

Therefore, the distance between the two check point (C and D) is 4920 ft

Hello,

a) We know the binomial coefficients are all integers, so

[tex]\dfrac{p!}{k!(p-k)!}[/tex]

is an integer.

And we can notice that the numerator p! is divisible by p.

If we take [tex]1\leq k\leq (p-1)[/tex]

It means that k! does not contain p, and we can say the same for (p-k)!

So, we have no p at the denominator so the binomial coefficient is divisible by p, meaning this is 0 modulo p.

b) We can write that

[tex]\displaystyle (x+y)^p=\sum_{i=0}^{p} \ {\dfrac{p!}{i!(p-i)!}x^{p-i}y^i[/tex]

We use the result from question a) and the binomial coefficients are 0 modulo p for i=1,2 , ... p-1 so there are only two terms left and then,

[tex](x+y)^p=x^p+y^p \text{ modulo p}[/tex]

c) Let's prove it by induction.

step 1 - for x = 0

This is trivial to notice that

[tex]0^p=0 \text{ modulo p}[/tex]

Step 2 - we assume that this is true for k

meaning [tex]k^p=k \text{ modulo p}[/tex]

and we need to prove that this is true for the k+1

We use the results of b)

[tex](k+1)^p=k^p+1^p=k^p+1 \text{ modulo p}[/tex]

and we use the induction hypothesis to say

[tex](k+1)^p=k^p+1^p=k^p+1=k+1 \text{ modulo p}[/tex]

And it means that this is true for k+1

Step 3 - conclusion

We have just proved by induction the Fermat's little theorem.

p a prime number, for for all x integers

Answer:

x = 4

Step-by-step explanation:

We can first expand 5(x-10), getting 5x - 50.

Thus, 5x - 50 = 30 - 15x

We can then isolate x, getting (5+15) x = 30 + 50

20 x = 80

x = 4.

Answer:

5(x - 10) = 30 - 15x

We distribute 5 (x-10)

So 5x-50 = 30 -15x

5x+15x=50+30

(-15x became 15x because we brought it back to the other side and -50 became 50 because we brought it back to the other side to put the x's with the x's and the digits with the digits.)

So 20x=80

x= 50/20

We simplify 80/20

So x=4

Answer:

A. 8

Step-by-step explanation:

32 divided by 4 = 8

The answer is a. 8 in.

Since the width of the rectangle is 4 inches (in) and the area of the rectangle is 32 in², we need to find the length of the rectangle.

We know that the area of a rectangle with length, L and width, W is A = LW.

Since we need to find the length of the rectangle, we make the length, L subject of the formula.

Since A = LW,

L = A/W

Given that A = 32 in² and W = 4 in

Substituting the values of the variables into the equation, we have

L = 32 in²/4 in

L = 8 in

So, the length of the rectangle is 8 in

So, the answer is a. 8 in.
