Answer:

A. ∆ABD ≅ ∆CDB by the SAS Postulate.

Step-by-step explanation:

You know lines AB and DC are congruent because of the lines on each. Additionally, angles B and D are congruent for the alternative interior angles rule and they also are marked as congruent in the image. Finally, DB is congruent to DB because of the reflexive property. So you have two sides and the included angle, this makes the SAS postulate true.

Answer:

80% of 100

Step-by-step explanation:

25% of something is basically dividing it by 4, meaning 25% of 200 is 50,

While 80% of 100 is 80

A good way to memorize this is if youre taking anything as a percent of 100, get rid of a 0 on the 100, and put a decimal place in the number.

(e.g. 90% of 10 is 9. whereas 90% of 100 is 90)

Just remember which you're dealing with!

Hope this helps!

Answer:

Step-by-step explanation:

25% of 200 is

80% of 100 is

As 80 > 50,  

the second number is greater

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The value of 25×8.5 is less than 250. The correct option is B.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The value of 25×8.5 is needed to be calculated in order to know if the product is more than 250 or not. Therefore, the value of the 25×8.5 can be calculated as,

25×8.5

= 25 × (85/10)

= 2125/10

= 212.5

Since the value of the product of 25 and 8.5 is 212.5 which is less than 250. It can be calculated that the number is smaller than 250.

Hence, the value of 25×8.5 is less than 250.

Step-by-step explanation:

Given

The function is

[tex]f(x)=3\sqrt{x}[/tex]

The function g(x) transform by shifting f(x) right 3 units.

To find:

The function g(x).

Step-by-step explanation:

The translation is defined as

[tex]g(x)=f(x+a)+b[/tex]

where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

The function f(x) shifts only 3 units right. So,

[tex]a=-3,b=0[/tex]

Now,

[tex]g(x)=f(x+(-3))+0[/tex]

[tex]g(x)=f(x-3)[/tex]

[tex]g(x)=3\sqrt{x-3}[/tex]               [tex][\because f(x)=3\sqrt{x}][/tex]

Therefore, the required function is [tex]g(x)=3\sqrt{x-3}[/tex].

Answer:

2 1/6 hours

Step-by-step explanation:

2 1/3 + 1 1/2 + x = 6

convert all mixed numbers to improper fractions

7/3 + 3/2 + x = 6/1

change all numbers to have a common denominator

14/6 + 9/6 + x = 36/6

combine like terms

23/6 + x = 36/6

subtract 23/6 from both sides

x = 13/6

f.  m∠14 + m∠17 = 180°          a║c                  Consecutive interior angles

From the given diagram and information, it can be concluded that lines a, b, and c are parallel, and lines d and e are parallel.

The given lines in the diagram are a, b, c, d, and e.

a. It is given that the measure of angle 13 is equal to that of angle 17.

Now, these two angles are made by lines a, c, and d. Now, the angles are corresponding and equal, and hence, lines a and c will be parallel.

b. It is given that the measure of angle 4 is equal to that of angle 9.

These two angles are made by lines d, e, and b. Now, the angles are alternate exterior and equal, and hence, lines d and e will be parallel.

c. It is given that the sum of the measure of angles 20 and 21 is equal to 180 degrees.

These two angles are made by lines a, b, and e. Now, the angles are supplementary and their sum is 180 degrees, and hence, lines a and b will be parallel.

d. It is given that the measure of angle 8 is equal to that of angle 19.

These two angles are vertically opposite angles between lines a and e.

e. It is given that the measure of angle 10 is equal to that of angle 23.

These two angles are made by lines b, c, and e. Now, the angles are alternate interior and equal, and hence, lines b and c will be parallel.

f. It is given that the sum of the measure of angles 14 and 17 is equal to 180 degrees.

These two angles are made by lines a, c, and d. Now, the angles are supplementary and their sum is 180 degrees, and hence, lines a and c will be parallel.

Therefore, it can be concluded that lines a, b, and c are parallel, and the lines d and e are parallel.

Answer:

3.95%

Step-by-step explanation:

An interest-bearing account paying a stated nominal or annual interest rate of 3.880% compounded monthly, would translate to an Annual Percentage Yield (APY) or Effective Annual Rate (EAR) of 3.95%. This means that $100.00 will grow to $103.95 ($103.95 rounded) after one year.

Point-slope form of the linear functions is like this :

[tex]y - y(point) = (slope) \times ( \: x - x(point) \: ) \\ [/tex]

[tex]y - 2 = \frac{3}{2}(x - 7) \\ [/tex]

So :

[tex]slope = \frac{3}{2} \\ [/tex]

And

Point = ( 7 , 2 )
