Given:
Total number of flower they buy = 29 stems
Total cost = $120.94
Lilies cost = $3.42 per stem
Peonies cost = $4.78 per stem
To find:
The number of lily stems and peony stems did they buy.
Solution:
Let number of lily stems = x
Number of lily stems and peony stems = y
According to given information,
[tex]x+y=29[/tex] ...(i)
[tex]3.42x+4.78y=120.94[/tex] ...(ii)
From (i) and (ii), we get
[tex]3.42x+4.78(29-x)=120.94[/tex]
[tex]3.42x+138.62-4.78x=120.94[/tex]
[tex]-1.36x=120.94-138.62[/tex]
[tex]-1.36x=-17.68[/tex]
Divide both sides by -1.36.
[tex]x=\dfrac{-17.68}{-1.36}[/tex]
[tex]x=13[/tex]
Put x=13 in (i).
[tex]13+y=29[/tex]
[tex]y=29-13[/tex]
[tex]y=16[/tex]
Therefore, number of lily stems is 13 and number of lily stems and peony stems is 16.
Are these two triangles congruent why or why not!!!!!!!!!???????? WORTH 24 POINTS AND I WILL GIVE YOU BRAINIEST!!!!!!1111
Answer:
not congruent
Step-by-step explanation:
These two triangles are not congruent because for two shapes to be congruent to each other, both needs to have same shape and size and clearly, we can see in this figure that both triangles although are the same shape, are different sizes so therefore these two triangles are not congruent. For example, the height of triangle ADE is 4 whereas the height of triangle CBA is 2.

Evaluate f(x)=x+6 when x=−2,0, and 5.
f(−2)=
f(0)=
f(5)=
thank you
Answer:
f(-2) = 4
f(0) = 6
f(5) = 11
Step-by-step explanation:
You just need to plug in the different values of x into the equation
f(x)=x+6
When x = -2, then f(-2) = -2 + 6 = 4
When x = 0, then f(0) = 0 + 6 = 6
When x = 5, then f(5) = 5 + 6 = 11
f(5) = 11 , f(0) = 6 , f(-2) = 4
Given expression:
f(x) = x + 6
Find:
f(−2), f(0), f(5)
Computation:
f(x) = x + 6
When x = -2
f(-2) = -2 + 6
f(-2) = 4
When x = 0
f(0) = 0 + 6
f(0) = 6
When x = 5
f(5) = 5 + 6
f(5) = 11

The grades on a history midterm at Gardner Bullis are roughly symmetric with μ = 69 μ=69mu, equals, 69 and σ = 3.5 σ=3.5sigma, equals, 3, point, 5. Ishaan scored 65 6565 on the exam. Find the z-score for Ishaan's exam grade. Round to two decimal places.
Answer:
-1.14
Step-by-step explanation:
The given information in statement is
mean=μ=69
standard deviation=σ=3.5
Let X be the Ishaan's exam score
X=65
The Z score can be computed as
[tex]z=\frac{x-mean}{standard deviation}[/tex]
[tex]z=\frac{65-69}{3.5}[/tex]
z=-1.1429
z=-1.14 (rounded to two decimal places).
Thus, the computed z-score for Ishaan's exam grade is -1.14.

Fitness For cardiovascular exercise, you do a combination of walking and running
for 60 minutes. During the 60 minutes, you end up running twice as much as
walking. Let x represent the number of minutes you ran and y represent the
number of minutes you walked. How many minutes did you run and how many
did you walk?
Answer:
You walked for 20 minutes and ran for 40 minutes
Step-by-step explanation:
System of Equations
Let x = the number of minutes you ran
y = the number of minutes you walked
Walking and running takes a total of 60 minutes, thus:
[tex]x+y=60\qquad\qquad [1][/tex]
Running time is twice as much as walking time, thus:
[tex]x=2y\qquad\qquad [2][/tex]
Solve the system by substitution. Taking x from [2] and substitute in [1]:
2y+y=60
Simplifying:
3y=60
Solving:
y=60/3=20
Calculate x from [2]:
x=2*20=40
You walked for 20 minutes and ran for 40 minutes

The local furniture store pays $300 for a dining room table and sells it with a 40% markup.
What is the selling price of the dining room table?
Answer:
$420
Step-by-step explanation:
The wholesale price is $300 and the markup is 40% of that, or
0.40($300) = $120
and so the selling price is $300 + $120 = $420
An easier way to calculate this is to multiply $300 by (1.00 + 0.40), or (1.40), which again comes out to $420.
Answer:
$420!

Naoko is building a small art shed in the backyard. She created a blueprint of the floor plan with a scale of 1⁄4 in. To 1 ft. According to the blueprint, the art space has dimensions of 2 1/2 in. By 1 in. What are the dimensions of her art shed in feet?
Answer: 10 feet by 4feet
Step-by-step explanation:
From the question, we are informed that Naoko is building a small art shed in the backyard and that she created a blueprint of the floor plan with a scale of 1⁄4 in. to 1 ft. This means that 1 inch will be to 4 feet.
Since the art space has dimensions of 2 1/2 in. by 1 in. This will be:
= (2 1/2 × 4) by (1 × 4)
= 10 feet by 4 feet
The dimensions of her art shed in feet are 10 feet by 4 feet.
