At the beginning of the Occupation, the Nazis basically let the Jews go about their business. This all changes in October 1940. Measures are introduced one after the other. Civil servants must sign an official declaration stating whether they are Jewish or not. Just like in Germany earlier on, Jewish civil servants and teachers are fired from their jobs. At the beginning of 1941, all Jews in the Netherlands must register.

[tex]\frac{13}{20}[/tex], or 0.65 miles.

Convert both to common denominator, then add together.

They have a common denominator of 20.

[tex]\frac{1}{4}[/tex] × [tex]\frac{5}{5} = \frac{5}{20}[/tex]

[tex]\frac{2}{5}[/tex] × [tex]\frac{4}{4} = \frac{8}{20}[/tex]

[tex]\frac{5}{20} + \frac{8}{20} = \frac{13}{20}[/tex]

Answer:

I would walk [tex]\frac{13}{20}[/tex] or 0.65 miles.

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] + [tex]\frac{2}{5}[/tex] = [tex]\frac{5}{20}[/tex] + [tex]\frac{8}{20}[/tex] = [tex]\frac{13}{20}[/tex] or 0.65

where y2 = -1, y1 = -7, x2 = -1, x2 = -3

[tex] \frac{ - 1 - ( - 7)}{ - 1 - ( - 3)} = \frac{ - 1 + 7}{ - 1 + 3} [/tex]

Since Point B is a point of tangency, there is a right angle being created on the edge of that circle.

This means that the Pythagorean Theorem can be applied to solve for r.

[tex]a^2+b^2=c^2[/tex]

[tex]r^2+24^2=(16+r)^2[/tex]

*A common mistake here is distributing the square to both 16 and r, whereas you should be multiplying 16+r by itself (FOIL).*

[tex]r^2+576=r^2+32r+256[/tex]

The [tex]r^2[/tex]s cancel.

[tex]32r+256=576[/tex]

[tex]32r=320[/tex]

[tex]r=10[/tex]

The radius r of Circle C is 10.

Answer:

Angle x is 38.

Step-by-step explanation:

If its congruent it means it is equal. Vertical angles are equal to each other.

The measure of x is 38°.

The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.

Corresponding angles are equal.

We have,

Vertical angles are congruent.

x° and 38° are vertical angles.

Now,

x° = 38°

Thus,

The value of x is 38°.

The true statement is (b) 3 is in the domain of f º g.

The functions are given as:

[tex]f(x) = \sqrt{x + 9[/tex]

g(x) = 9x - 4

The function f º g(x) is calculated using:

f º g(x) = f(x)* g(x)

This gives

[tex]f\ o\ g(x) = \sqrt{x + 9} *(9x - 4)[/tex]

Set the radicand greater to 0

[tex]x + 9 \ge 0[/tex]

Solve for x

[tex]x \ge - 9[/tex]

Answer:

89·98 mph

Step-by-step explanation:

First, we get the circumference of the tires:

Circumference = [tex]\pi[/tex] × (radius × 2)

Circumference = 3.142 × (1·5 × 2)

Circumference = 3·142 × 3

Circumference = 9·426 ft

The circumference of the tire is equal to one round.

      1 round = 9·426 ft

840 rounds = ?

We cross multiply to get the length that the tires would cover in a minute

= 840 × 9·426

       1

    1 minute = 7917·84 ft

60 minutes = ?

60 × 7917·84

          1

= 475070·4 ft

      5280 feet = 1 mile

475070·4 feet = ?

475070·4 × 1

     5280

475070·4 ÷ 5280 = speed of the car in mph

89·97545

Round this off to 2 decimal places...

= 89·98 mph

Answer:

Step-by-step explanation:

x+102+115+(180-115)=360

x+282=360

x=78 degrees

y=115 degrees

Answer:

x = 78

y= 115

Step-by-step explanation:

On the angle where p and m meet, we have congruent angles that both equal 102 degrees. The adjacent angles will add up to 180 degrees on a line. So, to find the missing angle, do this:

180-102 = 78 degrees

x is equal to the top right angle where p meets m as they are congruent.

x = 78

You can find y by realizing that the given angle on q meets n are congruent angles. If this angle equals 115 degrees, then y must also equal 115 degrees.

For the given triangle the measurement of the angle 'a' is 50 degrees.

Use the definition of isosceles triangle defined as:

A triangle with two equal-length sides is said to be isosceles. An isosceles triangle has equal angles on either side of its equal sides.

In the given triangle:

Two sides are of equal length

One angle is 65 degrees and the other is of 'a' degree.

Since we know that,

For an isosceles triangle,

Two sides and two angles of the opposite side are equal.

Therefore,

The third angle of the triangle is also 65 degrees.

Since we know that,

The sum of the interior angles of a triangle = 180 degrees.

Therefore,

a + 65 + 65 = 180

a = 180 - 130

a = 50 degree

Hence,

The measure of an angle is 50 degrees.

The statement fourth "The population is all text messages she sent and the sample is the 50 text messages she randomly selected" is correct.

Simple random sampling is a sampling strategy in which every item in the population has an equal probability of being chosen for the sample.

We have:

A student would like to know what proportion of the text messages she sends is to her best friend.

The number of sample methods she selects =  50 text messages

As the sample consists of the 50 texts she randomly chose from the population of all the texts she sent.

Thus, the statement fourth "The population is all text messages she sent and the sample is the 50 text messages she randomly selected" is correct.
