Equation to model the situation is ( 3.5x + 22.5 ) = 3(x+10), Option A.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Given data are :
The number of roses = x,
Price of each rose = $ 3.50,
So, the total price of roses = 3.5x dollars.
Now, the number of carnations = 10,
The cost of each carnation = $2.25,
So, the total cost of all carnations = 10 × 2.25 = $ 22.5,
Thus, the total cost of a bouquet of flowers = ( 3.5x + 22.5 ) dollars,
Also, the total numbers of flower = x + 10.
Hence, the average cost of flowers = Total cost / total flowers
average cost flowers = ( 3.5x + 22.5 ) / (x+10)
According to the question,
The average cost of flowers = $ 3.00
( 3.5x + 22.5 ) / (x+10) = 3
or,
( 3.5x + 22.5 ) = 3(x+10)
Therefore, equation to model the situation is ( 3.5x + 22.5 ) = 3(x+10).

[tex] \cos(330) = \frac{ \sqrt{3} }{2} [/tex]
Prove that:
[tex] \tan(165) = \sqrt{3} - 2[/tex]
Please solve this question.
Answer: see attachment
Step-by-step explanation:
Given: cos 330 = √3/2
Prove that tan (165) = √3 - 2
Step-by-step explanation:
cos330° = cos(360° - 30°) = cos(2π - 30°)
Using, cos(2π - x) = cosx, x < 90°
=> cos(2π - 30°)
=> cos(30°)
=> √3/2 , proved
(ii): tan(165°) = tan(180° - 15°) = tan(π - 15°)
Using, tan(π - x) = - tanx
=> tan(π - 15°)
=> - tan15°
=> - (-√3 + 2)
=> √3 - 2 proved
For tan15° :
Using, tan2x = 2tanx/(1 - tan²x)
tan30° = 2tan15°/(1 - tan²15°)
1/√3 = 2tan15° / (1 - tan²15°)
1 - a² = 2√3 a {a = tan15°}
Solving this we get, a = -√3±2
As a = tan15°, it can't be -ve, thus
a = tan15° = -√3 + 2

Diego is thinking of two positive numbers, if we triple the first number and double the second number the sum is 34. Diego then says, "if we take half of the first of the first number and double the second number, the sum is 34. What are Diego’s two numbers?
Answer:
1st number: 0
2nd number: 17
Step-by-step explanation:
3x+2y=34 x is the first number, y is the second.
1/2x+2y=34 multiply each number by two to get rid of the integer by the variable x.
x+4y=68 solve for x.
x=68-4y add this into the first equation to solve for variable y.
3(68-4y)+2y=34 solve for y.
204-10y=34
-10y= -170
y=17
now to solve for x
x= 68-4(17)
x= 0

Volunteers at Sams school use some of the student councils savings for a special project.They buy 4 backpacks for $9 each and fill each backpack with paper and pens that cost $5.By how much did the student councils savings change because of this project?
Answer: The student councils savings change by $41.
Step-by-step explanation:
Number of backpacks = 4
Cost of each backpack = $9
Paper and pen costs = $5
Total spending = (Number of backpacks ) x (Cost of each backpack ) + (Cost of paper and pen)
= $ (4 x 9 +5)
= $ 41
Hence, the student councils savings change by $41.

If an object is projected upward with an initial velocity of 48 ft per second from a height h of 64 ft, then its height t seconds after it is projected is defined by the equation f(t) = -16(t) with superscript (2) + 48t + 64. How many seconds after it is projected will it hit the ground?
Answer:
4 seconds
Step-by-step explanation:
Given that :
Height of a projected object is modeled by:
f(t) = - 16t² + 48t + 64
t = height
How many seconds after projection will it hit the ground ;
When the projectile hits the ground ; t = 0
f(t) = - 16t² + 48t + 64
f(t) = 0
- 16t² + 48t + 64 = 0
Divide through by - 16
t² - 3t - 4 = 0
t² - 4t + t - 4 =0
t(t - 4) +1(t - 4) = 0
(t +1) = 0 or (t - 4) = 0
t = - 1 or t = 4
t can't be negative ;
Hence, the projectile will hit the ground after 4 seconds

Answer:
Step-by-step explanation:
Givens
P = 2*L + 2*W
P = 70
w = 16
Solution
70 = 2L + 2*16
70 = 2L + 32

what is the sum of zeros of the equation (m-10)(6m-1)=0. Ancwer your question as a fraction
PLSSS SOMEONE ANCWEE THISS BEGGINGG.
Answer:
The sum of zeros is [tex]\frac{61}{6}[/tex]
Step-by-step explanation:
The Rule of Zero Product
The rule of zero product states that the product of two nonzero elements is nonzero. It can be written as the following assertion:
If a.b=0, then a=0 or b=0
The equation
(m-10)(6m-1)=0
can be solved by applying the mentioned rule:
[tex]m-10=0 \ \ \Rightarrow m=10[/tex]
[tex]6m-1=0 \ \ \Rightarrow m=1/6[/tex]
The sum of both solutions is:
[tex]\displaystyle 10+\frac{1}{6}=\frac{61}{6}[/tex]
The sum of zeros is [tex]\mathbf{\frac{61}{6}}[/tex]

Answer: The answer is Y=3/4x -4.5
Step-by-step explanation: You can find the slope by unsing rise over run by using the points given, you go up 3 and go to the side 4 times to get to the other point. You use tose 2 numbers and put them into a fraction you put it like this(The amount you went up/ the amount you went to the side) the you find where you cross the y-intercept which is 4.5 the you plug it into the point slope formula which is Y=3/4x -4.5

Convert the following repeating decimal to a fraction in simplest form.
.72
Answer:
The real answer is 8/11
Step-by-step explanation:
The fractional value of 0.72 is 18/25.
What is Decimal?A decimal is a number with a whole and a fractional part. Decimal numbers are between integers and represent numerical value for whole plus some fraction of a whole.
A decimal number comprises two parts: a whole number component and a fractional component. The decimal place value system is the same as the whole number value system for the whole component of a decimal number.
Given:
We have the decimal number 0.72.
Now, we can remove the decimal and put the number of zeroes in the denominator.
So, 0.72
= 72/100
Now, simplifying the fraction as
= 36/ 50
= 18/25
Now put decimal point ahead of two number from the numerator.
So, 37/100 = 0.37
So, the decimal is 0.37.
