Answer:
y = 15x + 65, or y = 15(9) +65
Step-by-step explanation:
So first, subtract $65 from $200 because Brittany is already using $65 for a plantar. For y = mx+b, $65 would be the b, because b is the fixed number, the number that cannot be changed. At this point, you are at y = mx + 65.
Now you are left with $135. Brittany wants to buy flowers with the remaining money. What you can do is division to see how many times $15 will go in $135 because with one flower = $15, we want to see the maximum number we can spend. If you do the division, you will see that $15 goes into $135 9 times, meaning you can buy 9 flowers, because each flower is $15, maxing out the remaining money you have.
In equation form, $15 would be the m, because m is what you multiply by and x is the independent variable, or the number of flowers Brittany will buy.
y = 15x + 65, or y = 15(9) +65

Which equation represents the line that passes through the point (-1.2, -5.6) and has a slope of -2.9
Answer:
[tex]y+5.6 = -2.9 (x + 1.2)[/tex]
Step-by-step explanation:
Equation of straight line in point slope form is given as
[tex]y -y_1 = m(x- x_1)[/tex] -------------(1)
Here
[tex]m =-2.9[/tex] and [tex](x_1, y_1) = (-1.2, -5.6)[/tex]
Substituting values in equation (1)
[tex]y+5.6 = -2.9 (x + 1.2)[/tex]
Which expression is equivalent to 15c+20?
Answer:
5 (3 c + 4)
Step-by-step explanation:
We factor out the 5, to get 5(3c+4)
We check by distributing the 5, and we get 15c+20 which is correct!
Hope this helps
The expression equivalent to 15c + 20 is 5(3c + 4).
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is 15c + 20.
We have to find an equivalent expression of this using the distributive property.
For three numbers or expressions a, b and c, Distributive property states that,
a (b + c) = ab + ac
In the expression of 15c + 20, write each terms as a multiple of a common factor.
15c = 5 × 3c
20 = 5 × 4
15c + 20 = (5 × 3c) + (5 × 4)
= 5 (3c + 4)
Hence the correct expression which is equivalent to the given expression is 5 (3c + 4).

Which of the following is equivalent to sin(30°)?
Question 2 options:
A) cos(60°)
B) cos(90°)
C) sin(60°)
D) cos(30°)
Answer:
A. cos(60°)
Step-by-step explanation:
sin(30 degrees) = 0.5
cos(60°) = 0.5
cos(90°) = 0
sin(60°) = √[tex]\frac{3}{2}[/tex]
cos(30°) = √[tex]\frac{3}{2}[/tex]
so it's A.
Ace
The sin 30° is equivalent to the expression cos 60°. Then the correct option is A.
What is trigonometry?Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
The equivalent is the expression that is in different forms but is equal to the same value.
The expression is given below.
⇒ sin(30°)
We know that the formula which is written as,
sin (90° - x) = cos x
Then by the above property, the expression is written as,
sin 30° = sin (90° - 30°) = cos x
sin 30° = cos 60°
The sin 30° is equivalent to the expression cos 60°. Then the correct option is A.

In a normal respiratory cycle the volume of air that moves into and out of the lungs is about 498 mL. The reserve and residual volumes of air that remain in the lungs occupy about 1990 mL and a single respiratory cycle for an average human takes about 4 seconds. Find a model for the total volume of air V(t) in the lungs as a function of time.
Answer:
The model is [tex]V(t)=2239+249\sin(\frac{\pi}{2}t)[/tex].
Step-by-step explanation:
Consider the given information.
The volume of air inside the lungs increases or decreases so for this we will use the basic sine function [tex]B(t)=d+a\sin[b(t+ \frac{c}{a})][/tex] as our parent function.
Let us assume that the phase shift is 0 it means [tex]\frac{c}{b}=0[/tex].
The air that moves into and out of the lungs is about 498 mL.
It means the amplitude of the function will vary by 249(half of 498).
The reserve and residual volumes of air that remains in the lungs occupy about 1990 mL which is the minimum air in the lungs.
So, the max air will be: 1990+498 =2488 mL
And the average will be d=1990+249=2239 ml
The horizontal stretch will be [tex]b=\frac{2\pi}{4}=\frac{\pi}{2}[/tex] as we know that period of [tex]y=\sin t[/tex] is [tex]2\pi[/tex] and respiratory cycle for an average human takes about 4 seconds.
Hence, the model is [tex]V(t)=2239+249\sin(\frac{\pi}{2}t)[/tex].

For the class picnic, 25 liters of punch were purchased. 6 liters were left over. How many gallons of punch were used at the picnic? (1 liter is approximately 0.26 gallons)
Answer:
Gallons of punch used = 4.94 gallons
Step-by-step explanation:
Given that:
Liters of punch purchased = 25 liters
Liters of punch left over = 6 liters
Liters of punch used = 25 - 6 = 19 liters
According to the given statement;
1 liter = 0.26 gallons
19 liters = 0.26*19 gallons
19 liters = 4.94 gallons
Hence,
Gallons of punch used = 4.94 gallons

3 is what percent of 75?
Answer:
4%
Step-by-step explanation:
First, we turn this into a fraction:
3/75 = 1/25 = 4%
So 3 is 4% of 75
Using the percentage expression 4 percent of the number 75 is 3.
We have,
Given percentage = M
Under the condition, an expression can be written as,
M% of 75 = 3
Solve for M.
M/100 x 75 = 3
Multiply 100 on both sides.
75M = 3 x 100
75M = 300
Divide 75 on both sides.
M = 300/75
M = 4
Cross checked.
4% of 755
4/100 x 75
4/4 x 3
1 x 3
3
True.
Thus,
4 percent of number 75 is 3.

An elliptical culvert is 3.5 feet tall and 6 feet wide. It is filled with water to a depth of 0.95 feet. Find the width of the stream.
Answer:
[tex]W_s \approx5.3[/tex]
Step-by-step explanation:
From the question we are told that
Height [tex]H=3.5ft[/tex]
Weight [tex]W= 6ft[/tex]
Depth [tex]D=0.95ft[/tex]
Generally the equation for ellipses is given as
[tex]\frac{x^2}{a^2} +\frac{y^2}{b^2} =1[/tex]
Where
[tex]b=H/2\\b=3.5/2\\Therefore\\b=1.75\\a=W/2\\a=6/2\\Therefore\\a=3\\[/tex]
[tex]\frac{x^2}{3^2} +\frac{y^2}{1.75^2} =1[/tex]
Generally to find y in the equation [tex]\frac{x^2}{a^2} +\frac{y^2}{b^2} =1[/tex]
[tex]y=-b+d[/tex]
[tex]y=-1.75+0.95[/tex]
[tex]y=-0.8[/tex]
Therefore
[tex]\frac{x^2}{3^2} +\frac{(0.8)^2}{1.75^2} =1[/tex]
[tex]\frac{x^2}{3^2} =1-\frac{(0.8)^2}{1.75^2}[/tex]
[tex]\frac{x^2}{3^2} =1-0.2089795918[/tex]
[tex]X^2 =3^2(1-0.2089795918)[/tex]
[tex]X^2 =7.119183674[/tex]
[tex]X =\sqrt{7.119183674}[/tex]
[tex]X =2.66817984[/tex]
Therefore the width of the given stream is
[tex]W_s=2.66817984*2[/tex]

Answer:
We have the three angles of a triangle as an equation, so we can add them together, and they equal 180.
So:
4x+10+12x-6+3x+5= 19x+9=180
19x=171 ... so: x= 171/19 = 9.
So ABC = 102 .. Obtuse angle
BAC = 46 .. Acute angle
BCA = 32 .. Acute Angle
Edit:
Angle 1 = 180 - BAC = 180 - 46 = 134
Angle 2= 180 - ABC = 180 - 102 = 78
