A business orders 215 flowers for their employees on Valentine's Day. Roses cost $3.00 each, carnations cost $1.00 each, and lilies cost $2.00 each. There are 15 more lilies than roses. The total of the order came to $410.00. How many of each type of flower were ordered?
Let, number of roses, carnations and lilies are x, y and z respectively.
So,
x + y + z = 215 ....1 )
It is given that total cost is $410.00 :
3x + y + 2z = 410 ....2 )
Also, there are 15 more lilies than roses.
z = x + 15 ....3 )
Putting value of z in eq 1 and 2 , we get :
x + y + x + 15 = 215
2x + y = 200 ....4 )
3x + y + 2( x + 15 ) = 410
5x + y = 380 ....5 )
Solving equation 4 and 5, we get :
3x = 180
x = 60
z = 60 + 15 = 75
y = 215 - 60 - 75 = 80
Therefore, number of roses, carnations and lilies are 60, 80 and 75 respectively.
Hence, this is the required solution.
A computer game involves creating words of five or more letters. At the beginning of each game, the computer assigns a points value of 1, 2, 3 or 4 to each letter of the alphabet, at random.
In the game that I am currently playing I have so far scored 14 points for EARTH, 12 points for CHART and 11 points for TRACE.
How many points would TEACHER score in this game? SHOW YOUR WORK
9514 1404 393
Answer:
18
Step-by-step explanation:
EARTH - TRACE = H - C = 14 - 11 = 3
For the given possible numerical values of the letters, the difference H - C = 3 means that ...
H = 4, C = 1
Then ...
CHART = ART + C + H = ART + 1 + 4 = 12
ART = 7
So, ...
TEACHER = EARTH +TRACE -ART = 14 +11 -7
TEACHER = 18

a stereo system cost 275 is on sale for 15% off .The sales person receives a 2% commission. How much of a commission do they receive?
Answer:
$4.68
Step-by-step explanation:
If the stereo is 15% of then you have to do 85% of 275
[tex].85*275= 233.75[/tex]
If the sales person only makes a 2% commission then we need to do 2% of 233.75
[tex].02*233.75=4.675[/tex]
Since money only goes to the hundredths place we need to round to the hundredths.
[tex]4.68[/tex]

The line has a slope of 7/10 and y- intercept of 3/1. Find the equation of the line.
Thereisalinewhoseslopeis0andwhose y -intercept is –6 . What isitsequationin slope -intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
The equation of a line with slope 0 and y-intercept -6 in slope-intercept form is [tex]y = -6[/tex].
Step-by-step explanation:
From Analytical Geometry we know that equation of the line in slope-intercept form is represented by:
[tex]y = m\cdot x + b[/tex] (Eq. 1)
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]m[/tex] - Slope, dimensionless.
[tex]b[/tex] - y-Intercept, dimensionless.
If we know that [tex]m = 0[/tex] and [tex]b = -6[/tex], then the equation of the line is:
[tex]y = 0\cdot x +(-6)[/tex]
[tex]y = -6[/tex]
The equation of a line with slope 0 and y-intercept -6 in slope-intercept form is [tex]y = -6[/tex].

Answer:
The figure is rotating clockwise
Step-by-step explanation:
Let us revise the cases of rotation
1. Rotation with positive direction (anti-clockwise)
- If the point (x, y) rotated about the origin by angle 90° anti-clockwise
∴ Its image is (-y, x)
- If the point (x, y) rotated about the origin by angle 180° anti-clockwise
∴ Its image is (-x, -y)
- If the point (x, y) rotated about the origin by angle 270° anti-clockwise
∴ Its image is (y, -x)
2. Rotation with negative direction (clockwise)
- If the point (x, y) rotated about the origin by angle 90° clockwise (-90°)
∴ Its image is (y, -x)
- If the point (x, y) rotated about the origin by angle 180° clockwise (-180°)
∴ Its image is (-x, -y)
- If the point (x, y) rotated about the origin by angle 270° clockwise (-270°)
∴ Its image is (-y, x)
From the given
∵ The figure is rotating around the origin by d degrees
∵ d < 0, which means d is negative
→ According to rule 2 above
∴ The direction of rotation is clockwise
∴ The figure is rotating clockwise

Leah is riding home from a friends house. After 5 minutes she is 4 miles from home. After 15 minutes she is 2 miles from home. Which equation models his distance, X if he is initially 5 miles from home? A) Y=5X-5 B) Y=11/7X-27/7 C) Y=0.2X+5 D) Y=-0.2X+5
Answer:
Y = - 0.2X + 5
Step-by-step explanation:
Given that:
Distance between Leah's home and friend's house = 5 miles
Distance X:
After 5 minutes, she is 4 miles from home
After 15 minutes, she is 2 miles from home
Hence ;
Change in distance with time (slope) :
(2 - 4) / (15 - 5) = -2 / 10 = -0.2
Initial distance from home (intercept) = 5
Hence, using the linear equation model:
Y = mx + c
m = slope or gradient ; c = intercept
Y = - 0.2X + 5

A tree casts a shadow 10 feet long. This person standing next to the tree casts a shadow 2.5 feet long. The triangle shown for the tree and its shadow
is proportional to the triangle shown for the person and their shadow. If this person is 5 feet tall, how tall is the tree?
Answer:
B/c the person is 5 feet tall but only casts a shadow 2.5 feet.. that's 1/2 his height, so the tree must also be casting a shadow 1/2 of it's height too, therefore the tree must be 20 feet tall
