A detergent company is trying to find a new stain remover ingredient to put in its detergent. Company managers know that baking soda or bleach will be used. The also know that water temperature, cold and warm, affects the stain removal process. An experiment will compare all combinations of these choices. Four types of stains on the same fabric will be subjected to each treatment and scored for stain removal quality. What is the experimental unit?
A: the fabric
B: the baking soda and bleach
C: the temperature of the water
D: the detergent
E: The Stains
Answer:
C.
Step-by-step explanation:
because they can pick bleach or bakeing soda the stans are going to come off either way but either\or hot and cold water affects it so they have to find out which of the water affects it not which of the prodocts does
Choose the situation in which the use of approximate numbers is most appropriate.
A)
planting trees in your yard
B)
ordering chairs for a kitchen table
purchasing barbeque to serve at a party
D
ordering uniforms for the high school basketbalt team
Answer:
I would say that A is your answer.
I think this because you would not need to have any specific number of trees in your yard, but you would need a specific number of things for all of your other options.
Step-by-step explanation:
You probably wouldn't approximate on how many chairs you put in a kitchen. What if you have a 5-member family and you aproxomate the chair number to 4. that would be useless so B is wrong.
C is wrong because you are only getting 1 barbaque. no approximation is nessisary for one item.
D is certainly wrong because you wouldn't want to leave out a uniform, that would mean one member of the basketball team may not get one.
-2=3+v
Help please ty very much
Answer:
v = -5
Step-by-step explanation:
to get v by itself, you must subtract 3 from both sides, not only to cancel out the positive 3 but to keep both sides equal. this leads to -5 = v so that's your answer.
Answer:
Your answer is: [tex]V= -5[/tex]
Solve for v by simplifying both sides of the equation, then isolating the variable.

10.Adrienne is going to deposit $8,500 in an account that earns 2.5% interest for 360 months. How much more interest will she earn if the account earns annual compound interest rather than annual simple interest?
Answer:
Difference= $3,090.15 in favor of compounded interest
Step-by-step explanation:
Giving the following information:
Present value (PV)= $8,500
Ineterest (i)= 0.025/12= 0.00208
Number of periods (n)= 360 months
We will calculate the future value of each option and determine the difference:
Simple interest:
FV= (PV*i*n) + PV
FV= (8,500*0.00208*360) + 8,500
FV= $14,864.8
Compounded interest:
FV= PV*(1+i)^n
FV= 8,500*(1.00208^360)
FV= $17,958.95
Difference= $3,090.15

PLEASE ANSWER THIS ASAP !!!!!!
Answer:
y = - x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 2) and (x₂, y₂ ) = (2, - 2) ← 2 points on the line
m = [tex]\frac{-2=2}{2+2}[/tex] = [tex]\frac{-4}{4}[/tex] = - 1 , thus
y = - x ← equation of line

[tex]\pink{\sf Third \: side \: of \: the \: triangle = 45}[/tex]
Solution :As, the given triangle is a right angled triangle,
Hence, We can use the Pythagoras' Theorem,
[tex]\star\:{\boxed{\sf{\pink {H^{2} = B^{2} + P^{2}}}}}[/tex]
Here,
H = Hypotenuse of triangleB = Base of triangle P = Perpendicular of triangleIn given triangle,
Base = 24Hypotenuse = 51Perpendicular = ?Now, by Pythagoras' theorem,
[tex]\star\:{\boxed{\sf{\pink {H^{2} = B^{2} + P^{2}}}}}[/tex]
[tex] \sf : \implies (51)^{2} = (24)^{2} + P^{2}[/tex]
[tex] \sf : \implies 51 \times 51 = 24 \times 24 + P^{2} [/tex]
[tex] \sf : \implies 2601 = 576 + P^{2}[/tex]
[tex] \sf : \implies P^{2} = 2601 - 576[/tex]
[tex] \sf : \implies P^{2} = 2025[/tex]
By squaring both sides :
[tex] \sf \sqrt{P^{2}} = \sqrt{2025}[/tex]
[tex] \sf : \implies P^{2} = \sqrt{2025}[/tex]
[tex] \sf : \implies P^{2} = \sqrt{(45)^{2}}[/tex]
[tex] \sf : \implies P^{2} = 45 [/tex]

Which mixture would taste different? Mixture 1: 1 cup water, 1.5 teaspoons drink mix Mixture 2: 2 cups water, 1/2 teaspoon drink mix Mixture 3: 1 cups water, 1/4 teaspoon drink mix Mixture 1 Mixture 2 Mixture 3
Answer:
Drink 1 will taste different.
Step-by-step explanation:
Given the mixtures:
Mixture 1: 1 cup water and 1.5 teaspoons drink mix
Mixture 2: 2 cups water and [tex]\frac{1}{2}[/tex] teaspoons drink mix
Mixture 3: 1 cup water and [tex]\frac{1}{4}[/tex] teaspoons drink mix
To find:
Which of the mixtures will taste different?
Solution:
To answer this, we need to find the ratio of all the mixtures.
First of all, Let us make ratio of water as 1 quantity.
Ratio of 1st mixture = 1 : [tex]\frac{3}{2}[/tex]
Ratio of Mixture 2 contains 2 cups of water.
Let us divide the ratio of mixture 2 with 2, we get:
[tex]\frac{2}{2}:\dfrac{\frac{1}{2}}{2}\\\Rightarrow 1:\dfrac{1}{4}[/tex]
Ratio of 3rd mixture = [tex]1:\frac{1}{4}[/tex]
Ratio of drink mix of 1st mixture with 1 cup water is different.
So, drink 1 will taste different.

x^2+13x+40 remainder 7. (or 7/(1-5))
Step-by-step explanation:
Answer:
x² + 13x + 40 + [tex]\frac{7}{x-5}[/tex]
Step-by-step explanation:
Using Synthetic division
dividing by ( x - 5) , thus use h = 5
5 | 1 8 - 25 - 193
↓ 5 65 200

Answer:
c) XY > RS
= true
Step-by-step explanation:
Firstly know the meaning of each sign given
> means is greater than
= means is equal to
a)XZ > ST
XZ = 8
ST = 11 - greater
= false
b) XY = RS
Due to the angles presented, we conclude that the greater the angle, the longer the unmeasured line.
XY is longer than RS
= false
c) XY > RS
= true
d) RS > XY
RS is shorter than XY hence not greater.
= false

A baker is putting cupcakes on trays to cool. She put 2 cupcakes on the first tray, 4 cupcakes on the second tray, 8 cupcakes on the third tray, 16 cupcakes on the fourth tray, and 32 cupcakes on the fifth tray. If this pattern continues, how many cupcakes will the baker put on the sixth tray?
Answer:
64 cupcakes
Step-by-step explanation:
Tray 1 = 2 cupcakes
Tray 2 = 4 cupcakes
Tray 3 = 8 cupcakes
Tray 4 = 16 cupcakes
Tray 5 = 32 cupcakes
Tray 6 = ?
This is a geometric progression
First term, a = 2
Common ratio, r = 4/2
= 2
6th term = ar^n-1
= 2 × 2^6-1
= 2 × 2^5
= 2 × 32
= 64
The 6th tray will have 64 cupcakes
