please help me! I need to find what the measure of angle VTS is​

Answer:

get it down to a unit rate firstt by dividing the 129.5 by 7 dvds

$18.50

18.5x2=37

the 2 dvds were 37 dollars

Step-by-step explanation:

The basic operation that is used in finding the cost of n number of products is multiplication, if we know the cost of 1 article then we can find the cost of n numbers of articles by multiplying it with the cost of one article. Therefore, the cost price of 2 DVD's is $37.

Amee buys 7 DVDS for $129.50.

Thus,

The cost price of 7 DVDs is $129.50

We need to find the cost price of 2 DVDs.

First let us find the cost price of 1 DVD.

Therefore,

[tex]7 \;\rm{DVD's}= \$129.50\\1 \; \rm{DVD}=\frac{129.50}{7}\\1 \; \rm{DVD}=\$18.5[/tex]

Therefore, the cost price of 2 DVDs is $37.

Answer:

Step-by-step explanation:

The first and the last of these functions are exponential functions.  Such functions can be recognized by the constant base and variable exponent found in each:  3^x, (5)^x, in this particular problem.

5x^2 is not an expo function because the base is not constant; this is called a power function.

the exponential function is f(x) = 3^x and 3(5)^x. Therefore, option a and d both are the correct answer.

The correct answers are f(x) = 3^x (choice A) and f(x) = 3(5) (choice D) for exponential functions, then it means you're considering a constant function (f(x) = 3(5)) as a simple form of an exponential function where the base is 3 and the exponent is 5.

This is a valid interpretation, but typically exponential functions are written as f(x) = a^x, where 'a' is a constant, and 'x' is the variable in the exponent.

In this case, if you're considering f(x) = 3(5) as an exponential function, it represents a specific case with a constant exponent.

So, both A and D can be considered as exponential functions depending on the context of the question.

Answer: 10 to the negative second power

Step-by-step explanation: To write 0.01 as a power of 10, first notice that 0.01 is a decimal which means that the exponent on our power of 10 will be negative.

To determine the value of the exponent, count the number of places we would need to move the decimal point in order to get 1.0.

In this problem, we would need to move the decimal point 2 places to get 1.0 which means that the exponent on our power of 10 will b -2.

Therefore, 0.01 can be written as 10 to the negative 2nd power.

To find the largest of two numbers when given their product and sum, we can use the quadratic formula.  Let's denote the numbers as 'a' and 'b'. We know that 'a * b = 24' and 'a + b = 10'. We can rewrite the second equation as 'b = 10 - a' and substitute it into the first equation.  Solving the quadratic equation, we find that the larger of the two numbers is 6.

we know that

If two figures are similar, then the ratio of its corresponding sides is equal

so

[tex]\frac{AB}{A'B'}=\frac{BC}{B'C'} =\frac{AC}{A'C'}[/tex]

substitute the values

Answer:  $183.71

Step-by-step explanation:

Original amount is $5,175.00

1st year: Increase of 9%

→  $5175(1 + 0.09)

=   $5175(1.09)

=  $5640.75

                                       2nd year: Decrease of 5%  

                                       → $5640.75(1 - 0.05)

                                       =  $5640.75(0.95)

                                                                               → $5358.71 - $5175.00

Step-by-step explanation:

We know that $5,175.00 was invested in a stock plan.

It increased by 9% in the first year:

[tex] 9% \times 5175.00 = 465.75 [/tex]

So value reached to (5175 + 465.75 = ) $5640.75

Then it second year, it lost 5% of its value:

Answer:

292

Step-by-step explanation:

The block is a rectangle with 80 yd length and 66 yd width. We need the perimeter of the block, which is the perimeter of the rectangle.

P = 2L + 2W

P = 2(80 yd) + 2(66 yd)

P = 160 yd + 132 yd

P = 292 yd

To calculate the distance of one lap around Danny's rectangular block (66 yards wide and 80 yards long), we find the perimeter, which is 292 yards.

The question asks about finding the distance Danny must run when doing a lap around his block, which is shaped as a rectangle. To find the distance around a rectangular path, we calculate the perimeter. The formula for the perimeter of a rectangle is 2 * (length + width). Given that the block is 66 yards wide and 80 yards long, the perimeter is 2 *(66 + 80) yards.

First, we add the length and width: 66 + 80 = 146 yards. Then, we multiply by 2: 2 * 146 = 292 yards. Therefore, one lap around Danny's block is 292 yards.

Answer:

C. b = -5/3

Step-by-step explanation:

9b2 + 30b + 25 =0

(3b)^2 + 30b +(5)^2  = 0  <---perfect square

(3b + 5)^2 = 0

(3b + 5) = 0

3b = -5

 b = -5/3

Answer

C. b = -5/3

Answer:

C. b = -5/3

Step-by-step explanation:

9b² + 30b + 25 = 0

We can factor: two numbers that add up to 30 and its' product is 225: 15 & 15.

So we have 9b² + 15b + 15b + 25 = 0.

We can change this to (3b + 5) (3b + 5), or (3b + 5)².

This means there is only one solution: 3b + 5 = 0.

This can be turned into 3b = -5 -> b = -5/3.

Answer:

a) 20 ways

b) 10 ways

Step-by-step explanation:

When the order of selection/choice matters, we use Permutations to find the number of ways and if the order of selection/choice does not matter, we use Combinations to find the number of ways.

Part a)

We have to chose 2 objects from a group of 5 objects and order of choice matters. This is a problem of permutations, so we have to find 5P2

General formula of permutations of n objects taken r at time is:

[tex]nPr=\frac{n!}{(n-r)!}[/tex]

Using the value of n=5 and r=2, we get:

[tex]5P2=\frac{5!}{(5-2)!} =20[/tex]

Therefore, we can choose 2 objects from a group of 5 given objects if the order of choice matters.

Part b)

Order of choice does not matter in this case, so we will use combinations to find the number of ways of choosing 2 objects from a group of 5 objects which is represented by 5C2.

The general formula of combinations of n objects taken r at a time is:

[tex]nCr=\frac{n!}{r!(n-r)!}[/tex]

Using the value of n=5 and r=2, we get:

[tex]5C2=\frac{5!}{2!(5-2)!} =10[/tex]

Therefore, we can choose 2 objects from a group of 5 given objects if the order of choice does not matters.

Answer:

0.78

Step-by-step explanation:

"The probability that a family with 5 children will have at least 2 boys" is equivalent to the complement 1 - P(family will have 1 or 0 boys).

We can use a calculator with statistical functions built in to calculate this probability.  The function needed is for binomial probability:  binom(n, p, x).

P(family will have 1 or 0 boys) = binomcdf(5, 0.5, {0, 1} ) produces two results:  one the probab. of having 0 boys and one the probab. of having 1 boy:  0.03125 and 0.1875.  We add these together, obtaining 0.21875.

Then we subtract this result from 1 to obtain The probability that a family with 5 children will have at least 2 boys:  1 - 0.21875 = 0.78125, which may be reasonably rounded off to 0.78.

Answer:

81.3%.

Step-by-step explanation:

This is  Binomial probability.

Prob( Getting 1 boy) = 5C1 (1/2)^5

= 0.156

Prob ( Getting all girls = 5C5  (1/2)^5

= .031.

So Prob( at least 2 boys = 1 - (0.156 + 0.031)

= 0.813

= 81.3%.

Answer:

The central angle ADC = 81°

Step-by-step explanation:

From the figure we can see a circle with circumference = 200 cm and arc ABC length = 45 cm

To find the central angle ADC

Circumference = 200 cm

Length of arc ABC = 45

we have

arc length = circumference * (central angle /360)

central angle = (arc length * 360)/circumference

   = (45 * 360)/200

   = 81 cm

Therefore the central angle ADC = 81°
