Answer:

30 yellow roses

Step-by-step explanation:

4:6 means that there are 10 parts all together

divide the total number of roses by the amount of parts.

50 divided by 10 is 5.

to find out red roses, do 5 times 4,

to find out yellow roses, do 5 times 6

lol, that would be biology

Answer:

53.1 degrees

Step-by-step explanation:

sin(x) = 12/15

sin(x) = 0.8

sin-1(0.8) = 53.1301

Answer:

x is equal to negative one, and y is equal to negative four.

Step-by-step explanation:

You can do this by solving one of the equations by either x or y, then substituting it into the other.  Let's solve the second one for y:

[tex]2y = 3x - 5\\y = \frac{3x - 5}{2}[/tex]

Now we'll substitute that into the first equation:

[tex]9x - 2y = -1\\9x - 2(\frac{3x - 5}{2}) = -1\\9x - 3x + 5 = -1\\6x + 5 = -1\\6x = -6\\x = -1[/tex]

So we now know that x is equal to -1.  We can simply substitute that into one of the original equations to find y:

[tex]2y = 3x - 5\\2y = 3(-1) - 5\\2y = -3 - 5\\2y = -8\\y = -4[/tex]

We now know that x is equal to -1, and y is equal to -4.  We can also check our answer by plugging that -4 into the other equation, and see if we still get -1:

[tex]9x - 2y = -1\\9x - 2(-4) = -1\\9x + 8 = -1\\9x = -1 - 8\\9x = -9\\x = -1[/tex]

So we know that our answer is correct.

Answer:

D

-5x + y = 7

x+3y = 5

Step-by-step explanation:

when you graph the equations, they are parallel. as you know, solutions are the point where the lines meet. if they are parallel, it's not possible for the lines to intersect.

Answer and Step-by-step explanation:

Lets solve each one and see which has solutions and which one doesn't have a solution.

__________________________________________________________

A) x + y = -6

   x + y = 12

Solve for y for one of the equations, then plug it into the other equation.

y = -6 - x                  

x + (-6 - x) = 12     =    -6 = 12  No Solution

__________________________________________________________

B) y = 2x + 5

   y = -3x + 1

2x + 5 = -3x + 1

4 = - 5x

[tex]-\frac{4}{5} =x[/tex] Solution

_________________________________________________________ C) y = 4x - 8

    y = 2x - 4

4x - 8 = 2x - 4

2x = 4

x = 2 Solution

__________________________________________________________

D) -5x + y = 7

     x + 3y = 5

x = 5 - 3y

-5(5 - 3y) + y = 7

-25 + 15y + y = 7

16y = 32

y = 2 Solution

So, A is the correct answer. Sorry for the late answer!

Answer:

h= 12.3

Step-by-step explanation:

Answer:

(3.1)(4.1)

Step-by-step explanation:

Answer: B) a + c = 10

8a + 5c = 59

Step-by-step explanation:

We know that 10 total people went, so the first equation has to be equal to 10. The total was $59, so the second equation should be set equal to $59. Now that the second equation is for cost, we must make it 8a + 5c to represent the cost of the adult and child tickets which are $8 and $5, respectively.

[tex]\boxed{\boxed{\pink{\bf \leadsto Option \ second \ is \ correct .}}}[/tex]

Given that , a group of 10 people went to see a movie. The cost to go to the movie is $8 for an adult and $5 for a child. The total cost for thegroup was $59.

Let :-

[tex]\implies \bf No. \ of \ adult \ be \ denoted \ by \ a. \\\\\bf \implies No . \ of \ Children \ be \ denoted \ by \ c . [/tex]

Since the total number of people in group is 10 . Then ,

[tex]\implies \bf n_{adult} + n_{children} = 10 \\\\\bf\implies \boxed{\bf a + c = 10 }[/tex]

Now , the cost for an adult is $8 and for a child is $5. Hence ,

[tex]\bf\implies n_{adult}\times cost_{adult} + n_{child}\times cost_{child} = Total \ cost \\\\\bf \implies a \times \$ 8 + c \times \$ 5 = \$ 59 \\\\\bf\implies \boxed{\bf 8a + 5c =\$ 59 }[/tex]

Hence our overall answer matches with second option .That is ,

[tex]\red{\bf Option \ 2 } \begin{cases} \bf a + c = 10 \\\\\bf 8a + 5c = 59 \end{cases}[/tex]

Answer:

Sale price of backpack is $19.5

Step-by-step explanation:

Original price of backpack = $26

Discount = 25%

We need to find sale price.

First we will find amount that will be discounted, and then subtract from original price.

So, Finding discount price

[tex]25\%of 26\\=\frac{25}{100}\times 26\\=6.5[/tex]

So, there will be discount of $6.5

Now, the sale price will be:

Sale price = Original Price - Discount

Sale Price = 26 - 6.5

Sale Price = 19.5

So, Sale price of backpack is $19.5

Answer:

$1.30 or 130 cents

Step-by-step explanation:

You divide 91 by 14 to get the amount per ounce and you would get 6.5. Then you multiply that by 20 to get the new amount which is 130, or $1.30.

Answer:

35

Step-by-step explanation:

2x = 2 times 4.5

    = 9

5y = 5 times 5.2

    = 26

2x + 5y is 9 + 26

= 35

35

Steps

2x + 5y

x = 4.5

y = 5.2

a. Substitute

2(4.5) + 5(5.2)

b. Multiply

9 + 26

c. Add

35

Therefore, the answer is 35.

Answer:

x ≈ 14.6

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos40° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{19}[/tex] ( multiply both sides by 19 )

19 × cos40° = x , then

x ≈ 14.6 ( to the nearest tenth )

Answer:

Jordin weighs 96 pounds

Step-by-step explanation:

The Mean Value of a Data Set

The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:

[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]

Where xi is the value of each data and n is the total number of values.

We are given the average weight of n=5 marathon runners:

[tex]\bar x=92[/tex]

Multiplying the formula by n and expanding the sum:

[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]

We are given the weighs of four of the runners:

[tex]5*92=89+95+90+90+x_5[/tex]

[tex]460=364+x_5[/tex]

Solving for x5:

[tex]x_5 = 460-364=96[/tex]

Jordin weighs 96 pounds
