Hence, 120 flowers were sold in total on that day as the Roses made up 35% of the total number of flowers.
what is unitary method ?In mathematics, the unitary approach entails determining the value of a single unit and then using that value to determine the value of a certain number of units. It is frequently applied to issues concerning rates and proportions as well as issues relating to ratios and proportions. The unitary method, for instance, would result in a cost of $5 for 5 apples if the price of 1 apple is $2. To calculate the overall cost using the unitary method, we would multiply the $2 worth of one apple by the quantity we wish to purchase. Therefore $5 would be spent on 5 apples, or $2 each.
given
Assume that "x" represents the total quantity of flowers sold on that particular day.
Roses made up 35% of the total number of flowers, which means that:
0.35x = 42
By dividing both sides by 0.35, we can determine the value of "x":
x = 120
Hence, 120 flowers were sold in total on that day as the Roses made up 35% of the total number of flowers.

30-60-90 triangle = 4, 8, 4*sqrt(3)45-45-90 triangle = 6, 6, 6*sqrt(2)Right triangle, but not special right triangle = 6, 8, 10Triangle but not a right triangle = 7, 8, 10Not a triangle = 7, 12, 19======================================================
Explanation:
The template for a 30-60-90 triangle is that the short leg x leads to hypotenuse 2x, and longer leg x*sqrt(3). If x = 4, then we get the sides 4, 8, 4*sqrt(3) which are the short leg, hypotenuse, and long leg in that order.
----------------
The template for a 45-45-90 triangle is that we have x as the leg length and x*sqrt(2) as the hypotenuse. If x = 6, then we end up with the sides 6, 6, 6*sqrt(2)
-----------------
The triangle with sides 6, 8, 10 is a right triangle because a = 6, b = 8, c = 10 makes a^2+b^2 = c^2 true. I'm using the converse of the pythagorean theorem. We don't have a special right triangle because these sides do not fit the templates mentioned in the previous two sections above.
-------------------
The triangle with sides a = 7, b = 8, c = 10 on the other hand will not make a^2+b^2 = c^2 true. Note that a^2+b^2 = 7^2+8^2 = 113 which is not the same as 10^2 = 100. However, a triangle is possible because adding any two sides leads to a sum larger than the third side (triangle inequality theorem).
-------------------
We cannot form a triangle with sides 7, 12, 19 because the sides 7 and 12 add to 7+12 = 19 but that's not longer than the third side 19.
The triangle inequality theorem says that if you want to form a triangle with sides a,b,c then the following three inequalities must all be true
a+b > c
a+c > b
b+c > a
find the zeros the polynomial fx=2x^2 +9x-5
pls help with steps
Answer:
-5 ; 1/2
Step-by-step explanation:
GIVEN :-
A quadratic polynomial f(x) = 2x² + 9x - 5TO FIND :-
Zeroes of f(x) = 2x² + 9x - 5GENERAL CONCEPTS TO BE USED IN THIS QUESTION :-
Lets say there's a quadratic polynomial f(x) = ax² + bx + c , whose factors are (x - α) & (x - β). To find the values of x for which f(x) will be zero , equate the factors of f(x) with 0.
⇒ (x - α) = 0 & (x - β) = 0
⇒ x = α & x = β
Hence, it can be concluded that if (x - α) & (x - β) are factors of f(x) , then α & β are the roots of f(x).
SOLUTION :-
Factorise f(x) = 2x² + 9x - 5.
Split its middle term.[tex]=> 2x^2 + 10x - x - 5[/tex]
Take '2x' common from first two terms & '-1' from last two terms.[tex]=> 2x(x + 5) - 1(x + 5)[/tex]
Take (x + 5) common from the whole expression.[tex]=> (x + 5)(2x - 1)[/tex]
So , the factors of f(x) are (x + 5) & (2x - 1). Now equate the factors with zero.
⇒ (x + 5) = 0 & (2x - 1) = 0
⇒ x = -5 & x = 1/2
∴ The zeroes of f(x) = 2x² + 9x - 5 are (-5) & (1/2)
VERIFICATION :-
1) Put x = -5 in f(x) = 2x² + 9x - 5
⇒ f(-5) = 2(-5)² + 9×(-5) - 5
= 50 - 45 - 5
= 50 - 50
= 0
2) Put x = 1/2 in f(x) = 2x² + 9x - 5
[tex]f(\frac{1}{2} ) = 2 \times (\frac{1}{2} )^2 + 9 \times \frac{1}{2} - 5[/tex]
[tex]= 2 \times \frac{1}{4} + \frac{9}{2} - 5[/tex]
[tex]= \frac{1}{2} + \frac{9}{2} - 5[/tex]
[tex]= \frac{ 1 + 9 - 10}{2}[/tex]

Find the composite area
Answer:
Area of the composite figure = 42 in²
Step-by-step explanation:
Composite area of the given figure = Area of the rectangle + Area of the right triangle
Area of the rectangle = Length × Width

= 30 in²
Area of the right triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(4)(6)[/tex]
= 12 in²
Area of the composite figure = 30 + 12

Find the cofunction of the expression with the same value as tan(2pi/11).
Answer:
The cofunction of [tex]\tan \frac{2\pi}{11}[/tex] is [tex]\cot \frac{7\pi}{22}[/tex].
Step-by-step explanation:
In trigonometry, a function is a cofunction of another if and only if [tex]f(A) = g(B)[/tex], where A and B are complementary angles. In this case, the complementary function of a tangent function must be a cotangent function, this is:
[tex]\tan \frac{2\pi}{11} = \cot \left(\frac{\pi}{2} - \frac{2\pi}{11} \right)[/tex]
[tex]\tan \frac{2\pi}{11} = \cot \frac{7\pi}{22}[/tex]
[tex]\tan \frac{2\pi}{11} = \frac{1}{\tan \frac{7\pi}{22} }[/tex]

This is an extremely important procedure to know. Make sure you understand what the basis of it is. Often times in higher physics, you don't have a proper relationships and this method (called dimensional analysis) is the only tool you have to work with.
So each term has at least 1 cancelation that occurs with the prior term. And it is the units that you look to cancel, and that determines which way to put the intermediate steps.

PLEASE HELP ME WITH THIS
Answer:
Step-by-step explanation:
angle 1=130 degree(being alternate angles)
angle 2=50 degree
angle 2 +130=180 degree(being co interior angle)
angle 2=180-130
angle 2=50 degree
Answer:
m<1 = 50
m<2 = 130
Step-by-step explanation:
From the picture, you can inference that m<1 looks like 130 degrees, and m<2 does not. You can tell because m<1 looks like a wide-angle, while m<2 looks like a closed-angle. So, m<1 is 130 degrees.
To find m<2 subtract 180 by 130 because 180 is the measure of a straight angle.
180 - 130 = 50
So m<1 = 50
Can someone explain to me how the Pythagorean theorem works??
Answer:
By the Pythagorean theorem, it follows that the hypotenuse of this triangle has length c = √a2 + b2, the same as the hypotenuse of the first triangle. Since both triangles' sides are the same lengths a, b and c, the triangles are congruent and must have the same angles. ... If a2 + b2 = c2, then the triangle is right.

I cover a certain distance in 3 hours. If my speed increases by 1/3, why is my travel time not also reduced by 1/3 (so travel the same distance in 2 hours)?
Answer:
t = 2.25 h
Step-by-step explanation:
In the case, I cover distance d in 3 hours
d = 3 * v₁ (1)
In the second case my speed increase by 1/3 then my speed is
v₁ + (1/3) v₁ = (3/3 + 1/3 ) *v₁
my new speed is (4/3) * v₁ and
d = (4/3)*v₁ * t (2)
Dividing (2) by (1) we get
1 = (4/3) *v₁*t/ 3*v₁
1 = (4/9)*t
t = 9/4 h
t = 2.25 h
Find the range of the function f(x)=x2+5 given the domain (-2,-1,0,1,2)?
Answer:
(5, 6, 9)
Step-by-step explanation:
The domain is basically the set of all x values while the range is the set of all y values, in this case, it's the values of f(x). To find the range, we can plug the x values into the equation:
f(-2) = 9
f(-1) = 6
f(0) = 5
f(1) = 6
f(2) = 9
Since we can't have repeats in the range, it would be: (5, 6, 9)
The surveyor sets up the instrument to determine the height at the highest point on the hill. She determines that she is standing at a horizontal distance of 100 m and sights the top of the hill using an angle of 17°. i) Let ‘h' represent the height of the hill and ‘d' represent the horizontal distance. ii) Set up the appropriate trigonometric ratio to determine the height of the hill. iii) Replace the variables with the appropriate values.
Answer:
[tex](a)\ h = d * \tan(\theta)[/tex]
[tex](b)\ h = 30.57m[/tex]
Step-by-step explanation:
Given
[tex]\theta = 17^o[/tex]
[tex]d =100m[/tex]
[tex]h = ??[/tex]
See attachment for illustration
Solving (a): Trigonometry ratio to calculate h.
From the attachment, we have:
[tex]\tan(\theta) = \frac{h}{d}[/tex]
Multiply both sides by d
[tex]d * \tan(\theta) = \frac{h}{d} * d[/tex]
[tex]d * \tan(\theta) = h[/tex]
Rewrite as:
[tex]h = d * \tan(\theta)[/tex]
Solving (b): The value of h
We have:
[tex]\theta = 17^o[/tex]
[tex]d =100m[/tex]
So:
[tex]h = 100m * \tan(17^o)[/tex]
[tex]h = 100m * 0.3057[/tex]
[tex]h = 30.57m[/tex]

Round answer to the nearest hundredth
Answer:
10.7
Step-by-step explanation:
use
a^2+b^2=c^2
...........
Answer:
x ≈ 10.72
Step-by-step explanation:
Use the Pythagorean Theorem, or
a² + b² = c²
to find x.
a² + b² = c²
9² + x² = 14²
81 + x² = 196
Subtract 81 from both sides.
x² = 115
Take the square root.
x = √115
When rounded to the nearest hundredth as a decimal, the answer is
x = 10.72.
