Answer:

none

Step-by-step explanation:

110 + 60 = 170

but 170 is obviously not 180 sooo none will be 60 degrees

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:

The equation for constant of proportionality is:

y = kx

K = Constant of proportionality

An example:

4y = 8x

=> 4y/4 = 8x/4

=> y = 2x

In the answer, y = 2x;   2 is the constant of proportionality

Answer:

it is ratio of the amount s y and x:k = y/x. put another way: y = Kx.

Example:- you are paid 20 rupaye an hour the constant of proportionality is 20

because pay = 20 hours worked

Answer: volume is 9 cubic units

===================================================

Explanation:

Each cross section is a square with side length x, so the area of this cross section is x^2

We're integrating from x = 0 to x = 3

So we have

[tex]\displaystyle f(x) = x^2\\\\\\\displaystyle g(x) = \int x^2 dx = \frac{1}{3}x^3+C\\\\\\\displaystyle \int_{a}^{b} f(x) dx = g(b) - g(a)\\\\\\\displaystyle \int_{0}^{3} x^2 dx = g(3) - g(0)\\\\\\\displaystyle \int_{0}^{3} x^2 dx = \left(\frac{1}{3}(3)^3+C\right) - \left(\frac{1}{3}(0)^3+C\right)\\\\\\\displaystyle \int_{0}^{3} x^2 dx = 9\\\\\\[/tex]

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:

C

Step-by-step explanation:

So we have:

[tex]\frac{6^{\frac{3}{10}}}{6^\frac{1}{5}}[/tex]

To simplify, we can use the quotient rule of exponents, which says that if we have:

[tex]\frac{x^a}{x^b}[/tex]

Then this equals:

[tex]=x^{a-b}[/tex]

So, our equation will be:

[tex]\frac{6^{\frac{3}{10}}}{6^\frac{1}{5}}\\=6^{\frac{3}{10}-\frac{1}{5}}[/tex]

Subtract the exponents. Turn 1/5 into 2/10 by multiplying both layers be 2. Thus:

[tex]6^{\frac{3}{10}-\frac{1}{5}}\\=6^{\frac{3}{10}-\frac{2}{10}}[/tex]

Subtract in the exponent:

[tex]=6^{\frac{1}{10}}[/tex]

So, our answer is C :)

Answer:

[tex]10^{11}[/tex]

Step-by-step explanation:

A statement is given i.e. "ten to the eighth divided by ten to the negative third."

It means that 10 to power 8 divided by 10 to the power -3.

Mathematically,

[tex]\dfrac{10^8}{10^{-3}}[/tex]

We know that, [tex]\dfrac{x^a}{x^b}=x^{a-b}[/tex]

Here, x = 10, a = 8 and b = -3

So,

[tex]\dfrac{10^8}{10^{-3}}=10^{8-(-3)}\\\\=10^{8+3}\\\\=10^{11}[/tex]

So, the answer is [tex]10^{11}[/tex]

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: x = -2

x + 9 = 7, Move the constant to the right.

x =7 -9 now calculate that.

then you get x = -2

Hope that helps ya out :D

Answer:

x+9=7

So x= 7-9

( 9 became -9 because we brought it back to the other side to have the x alone and the digits alone )

So x= -2

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.

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

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:

This means in the first week the number sells of digital copies is 308, paperback sells was 385 copies and hardback sell was 77 copies

Step-by-step explanation:

Let the number of digital copies be x, the number of paperback copies be y and the number of hardback copies be z.

4 digital sales is equal to 5 paperback sales and 1 hardback sale.

5x = 4y, x = 4z, y = 5z

The company sells 308 more paperback copies of the book than hardback copies

y = 308 + z

But y = 5z

5z = 308 + z

4z = 308

z = 77

y = 5z = 5(77) = 385

x = 4z = 4(77) = 308

This means in the first week the number sells of digital copies is 308, paperback sells was 385 copies and hardback sell was 77 copies

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.

[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]
