Answer: $1.50 per rose
Step-by-step explanation: You add 38 and 45, because you want to find the total of the roses she sold. 38 + 45 = 83. Then you have to divide the total price by how many roses she sold. So, 124.50 / 83 = 1.5. So, it's $1.50 per rose.

Give your answer in the form a square root b where a and b are integers.
Answer:
16[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the rule of exponents/ radicals
[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{a^{m} }[/tex] , then
[tex]n^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{n^2}[/tex] , then
[tex]\sqrt[3]{n^2}[/tex] = 8 ( cube both sides )
n² = 8³ ( take the square root of both sides )
n = [tex]\sqrt{8^3}[/tex]
= [tex]\sqrt{512}[/tex]
= [tex]\sqrt{256(2)}[/tex]
= [tex]\sqrt{256}[/tex] × [tex]\sqrt{2}[/tex]
= 16[tex]\sqrt{2}[/tex]

Step-by-step explanation:
Hope this helps. Pls give brainliest.
Please write a proof
Answer:
Step-by-step explanation:
∠X ≅∠Z : Given
∠ZYV≅∠XYU
∠ZVY≅∠XUY Because ∠ZYV≅∠XYU, ∠X ≅∠Z.
So ∠YVW≅∠YUW
Draw VU
ΔVWU is an isosceles triange so ∠UVW≅∠VUW
So ∠YVU≅∠YUV
Therefore ΔYVU is also an isosceles triangle and YV = YU
So ΔZYV≅ΔXYU ( ASA)
So XU = ZV ( because of CPCTC)
Therefore XU + WU = ZV = VW : XW = ZV
ΔXWV ≅ΔZWU ( ASA)

Answer:
sin^2(a) I believe. Delete my response if needed.
Step-by-step explanation:
tan²(α) (2 cos²(α) + sin²(α) - 1)
Recall that sin²(α) + cos²(α) = 1 for all α. Then sin²(α) - 1 = -cos²(α) :
tan²(α) (2 cos²(α) - cos²(α))
tan²(α) cos²(α)
Rewrite tan(α) = sin(α) / cos(α) :
(sin(α) / cos(α))² cos²(α)
(sin²(α) / cos²(α)) cos²(α)
Cancel the factors of cos²(α) :
sin²(α)

Answer:
C. [tex]-\frac{5}{6}[/tex]
Step-by-step explanation:
just use the equation [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex] So our first point (7,-5) will be [tex]x_1=7,y_1=-5[/tex]and our second point (10, -7.5) will be [tex]x_2=10,y_2=-7.5[/tex] Then substitute[tex]slope=\frac{(-7.5)-(-5)}{(10)-(7)}=\frac{-2.5}{3}=-\frac{5}{6}[/tex]Write an expression to find how many times Jason will blink in 60 minutes if he continues to blink 19 times a minute.

A tree is currently 10 feet tall and grows 2 feet per year. Show your work for full credit.
a. Model this scenario with an arithmetic sequence in explicit form. (2)
b. Rewrite the explicit form of the sequence using function notation. (2)
c. How tall will the tree be in 15 years? (1)
Answer:
(a) An = 2n +8
(b) F(n) = 10 + (n-1)2
(c) 38ft tall
Step-by-step explanation:
The tree is currently 10 feet long and grown 2 feet per year.
The arithmetic sequence is
10 , 12, 14 , 16 , 18 ..............
a( initial value) = 10 , d (common difference) = 2
Explicit forms
(a) An = a +(n-1)d
An = 10 + (n-1)2
= 10 + 2n -2
An = 2n +8
(b) F(n) = 10 + (n-1)2
(c) Height of the tree after 15 years
F(15) = 10 + (15-1)2
= 10 + 28
= 38ft
So the tree will be 38ft tall after 15 years.

Laqueta has three times as many quarters as Pablo if they each spend $.50 Laqueta will have five times as many quarters as Pablo how many quarters do Laqueta and Pablo have now?
Answer:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = 12
Step-by-step explanation:
Given that:
Laqueta has three times as many quarters as Pablo.
They both spend $0.50.
After that Laqueta will have 5 times as many quarters as Pablo.
To find:
Number of quarters with Laqueta and Pablo now?
Solution:
Let number of quarters with Laqueta = [tex]x[/tex]
Let number of quarters with Pablo = [tex]y[/tex]
As per given statement:
[tex]x=3y ..... (1)[/tex]
In $0.50, there are 2 quarters:
After spending $0.50, number of quarters left with both of them:
Number of quarters left with Laqueta = [tex]x[/tex] - 2 = [tex]3y-2[/tex]
Money left with Pablo = [tex]y[/tex] - 2
As per given statement:
[tex]3y-2 = 5(y-2)\\\Rightarrow 3y-2 = 5y-10\\\Rightarrow 2y = 8\\\Rightarrow y = 4[/tex]
Therefore, the answer is:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = [tex]3 \times 4[/tex] = 12

Enter the number that belongs in D= ?
Answer:
∠ D = 80°
Step-by-step explanation:
Δ BCA and Δ DCE are congruent ( SAS postulate )
Thus corresponding angles are congruent, thus
∠ D = ∠ B
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles in Δ ABC from 180° to find ∠ B
∠ B = 180° - (30 + 70)° = 180° - 100° = 80°, then
∠ D = 80°
