Answer:
r = (5000 - [(5000 x 0.3) + (4000 x 0.6) + (300 x 0.25)])0.8
Simplified - r = 820
Step-by-step explanation:
I don't know how to explain it exactly, but I know you have to find out how much the carnations, tulips, and irises all cost,subtract that from how much money he has, and divide what left by the cost of the roses (by multiplying the 0.8 cents, because it's a decimal).
r = (5000 - [(5000 x 0.3) + (4000 x 0.6) + (300 x 0.25)])0.8
r = (5000 - [1500 + 2400 + 75])0.8
r = (5000 - 3975)0.8
r = 1025(0.8)
r = 820
The equation which can be used to find the length of EF is option A which is EF=
.
Given the length of base of right angled triangle is 12 and the hypotenuse be 24.
We are to find the length of EF and tell which equation can be used to find the length of EF.
We know that pythagoras theorem applies in a right angled triangle.
Pythagoras theorem says that in a right angled triangle the square of the hypotenuse is equal to the sum of square of base and perpendicular.
![H^{2} =B^{2} +P^{2}](https://tex.z-dn.net/?f=H%5E%7B2%7D%20%3DB%5E%7B2%7D%20%2BP%5E%7B2%7D)
In this triangle we are only given base and hypotenuse and we have to find EF which is perpendicular.
![(DE)^{2} =(EF)^{2} +(DF)^{2}](https://tex.z-dn.net/?f=%28DE%29%5E%7B2%7D%20%3D%28EF%29%5E%7B2%7D%20%2B%28DF%29%5E%7B2%7D)
EF=![\sqrt{DE^{2}-DF^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7BDE%5E%7B2%7D-DF%5E%7B2%7D%20%20%7D)
=
--1
=![\sqrt{576-144}](https://tex.z-dn.net/?f=%5Csqrt%7B576-144%7D)
=![\sqrt{432}](https://tex.z-dn.net/?f=%5Csqrt%7B432%7D)
Hence the equation which can be used to find the length of Ef is option A which is EF=
.
Question is incomplete as it should include the figure also.

Let's say that y is the weight of the mother and x is the weight of the baby.
We know that the baby is 7437 pounds less than the mother, which means you need to add 7437 pounds to the baby's weight to get the mother's.
We can show it like this:
x+7437=y.
We know what the baby's weight is (1400 lbs), so just sub it in:
1400+7437=y
y=8837 lbs
The mom weighs 8837 pounds.
Answer:
Whether a net force acts on the object.
Step-by-step explanation:
Newtons first law states that an object will remain at rest unless it is acted upon by an imbalanced force.
The perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
<h3>
What is a perimeter?</h3>
A perimeter is a closed path that outlines either a two-dimensional shape or a one-dimensional length.
Given that the length is 3x+2 and the width is 2x-1. The perimeter of a rectangle is given below.
![P = 2 (L + W)](https://tex.z-dn.net/?f=P%20%3D%202%20%28L%20%2B%20W%29)
![P = 2 ( 5x +1)](https://tex.z-dn.net/?f=P%20%3D%202%20%28%205x%20%2B1%29)
![P =10x +2](https://tex.z-dn.net/?f=P%20%3D10x%20%2B2)
A polynomial function is a function that involves only positive integer exponents of a variable in an equation.
Hence we can conclude that the perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
