Can you plz help me

Mark and Julio are selling flower bulbs for a school fundraiser. Customers can buy bags of windflower bulbs and packages of croc

ikadub [295]

Answer:

Bag of windflower bulbs costs $8.50

Package of crocus bulbs costs $17.60

Step-by-step explanation:

Let $x be the price of one bag of windflower bulbs and $y be the price of one package of crocus bulbs.

1. Mark sold 2 bags of windflower bulbs for $2x and 5 packages of crocus bulbs for $5y. In total he earned $(2x+5y) that is $105. So,

2x+5y=105

2. Julio sold 9 bags of windflower bulbs for $9x and 5 packages of crocus bulbs for $5y. In total he earned $(9x+5y) that is $164.50. So,

9x+5y=164.50

3. You get the system of two equations:

$\left\{\begin{array}{l}2x+5y=105\\ \\9x+5y=164.50\end{array}\right.$

From the first equation

$5y=105-2x$

Substitute it into the second equation:

9x+105-2x=164.50

7x=164.50-105

7x=59.5

x=$8.50

So,

5y=105-2·8.5

5y=105-17

5y=88

y=$17.60

a bowler knocks down at least 6 pins 70% of the time. Out of 200 rolls, how many times can you predict the bowler will not down

Naddik [55]

Since he knocks at least 6 pins 70% of the time.

For 200 rolls:

70% of 200

= (70/100) * 200

= (7/10) * 200

= 140

140 times.

hope this helps :)

Answer:

I could be wrong, but I believe that the answer is D, none. This is because there is only proof of one congruent side and angle.

What equation(s) represent joint variations? check all that apply c=2pi z=3x/y y=3x+2 w=abc/4 v=lwh

Alinara [238K]

Answer:

Step-by-step explanation:

Joint variations occurs when one variable depends on the value of two or more variables. The variable varies directly or indirectly with the other variables combined together. The other variables are held constant. From the given examples, the equation(s) that represent joint variations are

1) z = 3x/y

z varies directly with x and inversely with y.

2) w = abc/4

w varies inversely with a,b and c. 4 is the value of the constant of variation.

If A is the set of prime numbers and B is the set of

Natasha2012 [34]

The correct option is (A) None.

The numbers of digits that are common to both sets is none.

In mathematics, a set is a group of distinct objects that form a group. A set can contain any type of group of items, such as a grouping of numbers, days of the week, vehicle types, and so on.

Each element inside the set is referred to as a set element. When writing a set, curly brackets are used.
A simple instance of a set could be as follows. Set A = {1,2,3,4,5}. A set's elements can be represented in a variety of ways.
A roster form or even a set builder form is typically used to represent sets.

Now, according to the question;

Set A = {1,3,5,7,11,13,17,19,......} Prime Number Collection (The numbers which have only two factors i.e, 1 and the number itself)

Set B {15,25,35,45,55,......} Set of two-digit positive integers with the unit digit ("5").

Each two-digit positive integer with such a unit digit of 5 has much more than two factors; Set B has 1,5 as well as "itself" as factors.

As a result, these two sets are disjoint sets (no common element).
