Answer:
25 degrees
Step-by-step explanation:
So a triangles angels equal 180 degrees
So for angel ECD 180 - (15+90) = 75
Straight lines also always equal to 180 degrees so
180 - (80+75) = 25
Measure of ∠BCE = 25° .
What is angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle. The word “angle” is derived from the Latin word “angulus”, which means “corner”.
Given, In figure,
∠CED = 15°
∠EDC = 90°
∠BCA = 80°.
In triangle ECD
Sum of all interior angles of a triangle is 180°
∠ECD +∠CED +∠EDC = 180°
∠ECD + 15° + 90° = 180°
∠ECD = 180° - 105°
∠ECD = 75°
Now,
∠BCA,∠BCE and∠ECD are at point C on line AD.
Sum of all angles made at one point of line is 180°.
∠BCA +∠BCE +∠ECD = 180°
80° + ∠BCE + 75° = 180°
∠BCE = 180° - 155°
∠BCE = 25°
Hence, 25° is measure of ∠BCE.

The number of visitors to a certain Web site triples every month. The number of visitors is modeled by the expression 900 * 3^m, where m is the number of months after the number of visitors was measured. Evaluate the expression for m=-2. What does the value of the expression represent in the situation?
Answers
Answer:
[tex]900\times 3^m[/tex] = 100
Step-by-step explanation:
The number of visitors is modeled by the expression [tex]900\times 3^m[/tex]
Where m is the number of months after the number of visitors was measured.
We need to evaluate the above expression for m = -2.
So,
[tex]900\times 3^m=900\times 3^{-2}\\\\=900\times \dfrac{1}{3^2}\\\\=900\times \dfrac{1}{9}\\\\=100[/tex]
At m = -2, the value of the above expression is equal to 100.

y = 17/2
Step-by-step explanation:
7y − 4 = 9y + 13 − 4y
Simplify both sides of the equation.
7y - 4 = 5y + 13
Subtract 5y from both sides.
2y - 4 = 13
Add 4 to both sides.
2y = 17
Divide both sides by 2.
y = 17/2

Jane is making wind seashells. She need 12 sea shells for the big one and 8 for the small one. How many wind chimes of the same number would she make form 100 sea shells?
Answers
Answer: See explanation
Step-by-step explanation:
Let the wind chimes of the same number that would make her form 100 sea shells be represented by x.
From the information given in the question, this can be denoted as:
12x + 8x = 100
20x = 100
x = 100/20
x = 5
She'll need 5 wind chimes. Let's check
12x + 8x
12(5) + 8(5)
60 + 40 = 100

Jackie's commute is 15 minutes longer than Laura's. If Laura drives 12 minutes for every 17 minutes Jackie drives what are both Jackie's and Laura's drives?
Answers
Answer:
Laura drives for [tex]36\ \text{minutes}[/tex] while Jackie drives for [tex]51\ \text{minutes}[/tex]
Step-by-step explanation:
Laura's commute is [tex]x\ \text{minutes}[/tex]
Jackie's commute is
[tex]x+15[/tex]
Laura drives 12 minutes for every 17 minutes Jackie drives so
For every minutes Laura drives Jackie drives [tex]\dfrac{17}{12}\ \text{minutes}[/tex]
So,
[tex]\dfrac{17}{12}=\dfrac{x+15}{x}\\\Rightarrow 17x=12x+180\\\Rightarrow 5x=180\\\Rightarrow x=\dfrac{180}{5}\\\Rightarrow x=36\ \text{minutes}[/tex]
Hence, Laura drives for [tex]36\ \text{minutes}[/tex] while Jackie drives for [tex]36+15=51\ \text{minutes}[/tex].

The expression for the given rectangle with width x and area y is[tex]y = -x^{2} +32[/tex]
it is given that
area of the rectangle = y
width of the rectangle = x
so the length of the rectangle will be = area/width = [tex]\frac{y}{x}[/tex]
perimeter = 64
What is the perimeter of a rectangle?Perimeter is the sum of all four sides of the rectangle.
we can say that,
2(length + breadth) = 64
[tex]2( \frac{y}{x} + x)=64\\\\[/tex]
[tex]\frac{y}{x} + x= 32[/tex]
[tex]\frac{y + x^{2} }{x} = 32[/tex]
[tex]y+x^{2} = 32x[/tex]
[tex]y = -x^{2} +32[/tex]
