C. 2
D. Infinite

Answer:

true

Step-by-step explanation:

because CD divided AB into equal halves, so they are of course perpendicular.

Answer:

Step-by-step explanation:

This is definitely true. AC is congruent to BD, and by the Isosceles Triangle Theorem, if this congruency is true, then the angles across from these congruent sides are also congruent. This means that angle ACD is congruent to angle BCD. That makes CD a bisector of angle ACB; it also makes CD a bisector of side AB. The definition of a perpendicular bisector is that the segment splits its angle in half (and it does) and that it splits the side it goes through in half (which it does). This makes CD, in a nutshell, the perpendicular bisector of AB (which also means that CD is perpendicular to AB).

Answer:

x = 50

Step-by-step explanation:

The base angles of an isosceles triangle are the same

The unmarked angle is also x

The sum of the angles of a triangle is 180

x+x+ 80 = 180

2x+80 =180

Subtract 80 from each side

2x+80-80 = 180-80

2x = 100

Divide by 2

2x/2 = 100/2

x = 50

Answer: A. mB = 24.8ᴼ

Step-by-step explanation:

A and B are complementary angles, which means they add to equal 90ᴼ.

To find mB, subtract mA from 90

90 - 65.2 = 24.8

Answer:

a = 0.5 or 1/2

b = 19/4 or 4.75

Step-by-step explanation:

Step 1: Isolate x's

x² - x = -5

Step 2: Complete the Square

x² - x + 1/4 = -5 + 1/4

(x - 1/2)² = -19/4

Step 3: Move everything to one side

(x - 0.5)² + 4.75

Answer:

See below.

Step-by-step explanation:

[tex]\frac{6z^2-12z}{4z^2-16z+16} +\frac{3z}{z^2-z-2} \\\\[/tex]

First, factor the numerators and the denominators:

[tex]=\frac{6z(z-2)}{4(z^2-4x+4)}+\frac{3z}{z^2-z-2}\\=\frac{6z(z-2)}{4(z-2)^2}+\frac{3z}{(z-2)(z+1)}\\=\frac{3z}{2(z-2)}+\frac{3z}{(z-2)(z+1)}[/tex]

Now, make the two denominators equivalent. To do this, we can multiply the first term by (z+1) and multiply the second term by 2. This will give us:

[tex](\frac{z+1}{z+1} )(\frac{3z}{2(z-2)})+(\frac{2}{2})(\frac{3z}{(z-2)(z+1)})\\=\frac{3z(z+1)}{2(z-2)(z+1)}+\frac{6z}{2(z-2)(z+1)} \\[/tex]

Now, combine them since they have a common denominator:

[tex]=\frac{3z^2+3z+6z}{2(z-2)(z+1)}\\ =\frac{3z^2+9z}{2(z-2)(z+1)} \\=\frac{3z(z+3)}{2(z-2)(z+1)}[/tex]

This cannot be simplified further.

Answer:

   16

 ____________

6| 96

  -6 |

       V

    36

  - 36

     0

6 goes into 9 one time because 9-6=3 so there is 1 six in 9. Write 1 at the top because you have 1 6.

Subtract the 6 and you get 3

Bring the 6 from 96 down

you get 36

6 goes into 36 6 times because 36-6-6-6-6-6-6=0 so write a 6 at the top and you get 16 because of the previous 1.

Subtract 36 by 36 to get 0

Hope this helps

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

You have to take each number in the dividend (number being divided) and divide it by the number in the divisor (number that is dividing). Here you would take 9, the first number in the dividend and divide it by 6, and you would put that in the first space of the quotient (answer). You would then take that number and multiply it by 6 and place it in the space below. Subtract 6 from 9 and get 3. Drop down the 6 to get 36. Take 36 and divide that by the divisor 6 and get 6 next to the number 1 you calculated earlier to get your answer 16. Take 6 and multiply it back to get 36 and subtract it from 36 to get a remainder of 0.

4:7

Answer:

4:7  

Step-by-step explanation:

I got it right on the test

Answer:

180

Step-by-step explanation:

Using the ratio flats : bungalows = 10 : 3

Given there are 30 bungalows then dividing by 3 gives the value of one part of the ratio.

30 ÷ 3 = 10 ← value of 1 part of the ratio, thus

10 parts = 10 × 10 = 100 ← number of flats

Using the ratio houses : flats = 9 : 5

The number of flats = 100 thus dividing by 5 gives

100 ÷ 5 = 20 ← value of 1 part of the ratio, thus

9 parts = 9 × 20 = 180 ← number of houses

Answer:

(C)221.5 miles

Step-by-step explanation:

Given a triangle with two sides a and b and an included(an angle between the two given sides) angle [tex]\theta,[/tex]

Area of the Triangle [tex]=\dfrac12 ab\sin \theta[/tex]

[tex]a=32$ miles\\b=23 miles\\\theta =37^\circ[/tex]

Therefore, The area of the portion that will not be farmed

[tex]=\dfrac12 \times 32 \times 23 \times \sin \37^\circ\\=221.47\\\approx 221.5$ square miles[/tex]

The correct option is C.

Irrational

Step-by-step explanation:

When we take the square root of both sides, we get z = 0.141421... and since there are no fractions and the decimals go endlessly on, it is irrational.

Answer:

If we have a x% sugar syrup, this means that the ratio between the amount of sugar and the total amount of syrup (water + sugar), times 100%, is equal to x%

So we if we have 100gr of sugar and m grams of water mixed, we have:

100gr + m = M =  grams of syrup, then we have:

then we have:

(100gr/M)*100% = x%

then

100gr*(100/x) = M

where M is the total amount of syrup that you can make.

Answer:

10000/x

Step-by-step explanation:

So, we can try to put this into an algebraic expression doing this!

We know that % means, *out of 100*, therefore

x=100

100=1        Which means, 100 over one equals to x over 100!

Cross multiply.

100*100 is 10,000

x*1 is x

you cannot simplify it further so we just leave it as, 10,000 divided by x, because x=10,000, would be 10,000 divided by x!

Cheers! I hope you can understand this now.

Significant figure can be defined in mathematics as the number of integers or digits in a number that tells us how significant and accurate the number is.

Rounding to 1 significant figure, 346 x 904  is 300000

When rounding a number to significant figures, the following rules are important.

346 multiplied by 904 is calculated as:

346 x 904 = 312794

Converting 312794 to 1 significant figure is 300000

Therefore, rounding to 1 significant figure, 346 x 904  is 300000.

Complete Question:

Determine whether the given value is a statistic or a parameter. A sample of 818 adults showed that 39% voted in the past election. Choose the correct answer below.

A. The value is a parameter because it is a numerical measurement describing some characteristic of a parameter sample.

B. The value is a statistic because it is a numerical measurement describing some characteristic of a statistic population.

C. The value is a statistic because it is a numerical measurement describing some characteristic of a statistic sample.

D. The value is a parameter because it is a numerical measurement describing some characteristic of a parameter population.

Answer:

C. The value is a statistic because it is a numerical measurement describing some characteristic of a statistic sample.

Step-by-step explanation:

If a sample of 818 adults showed that 39% voted in the past election. Therefore, the value is a statistic because it is a numerical measurement describing some characteristic of a statistic sample.

In Statistics, a sample can be defined as a set of data (individuals, observations or objects) collected from a larger statistical population using specific procedures. Therefore, a sample is a subset or part of population.

The difference between a statistic and a parameter is that; statistic is a numerical measurement describing some characteristic of a statistic sample while parameter is a numerical measurement describing some characteristic of a population.

In this scenario, a sample of 818 adults from the total population showed that 39% voted in the past election. The data collected represents a sample and as such, it is a statistic value.

Step-by-step explanation:

Formula: Center Not at Origin:

New point = k( x-a) +a, k( y-b) +b  where k is the scale factor and ( a,b) is center of dilation

New point = -2( x-4) +4, k( y-6) +6  

The scale factor is k = -2

Taking the top point ( 1,9)

New point = -2( 1-4) +4, -2( 9-6) +6

                   = -2(-3) +4 , -2(3) +6

                       6+4, -6+6

                         10,0  

Taking the bottom left point ( 1,7)

New point = -2( 1-4) +4, -2( 7-6) +6

                   = -2(-3) +4 , -2(1) +6

                       6+4, -2+6

                         10,4  

Taking the bottom right point ( 2,7)

New point = -2( 2-4) +4, -2( 7-6) +6

                   = -2(-2) +4 , -2(1) +6
