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 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

Find(x^3+8x^2-25x-193) divide (x-5) by using synthetic division.
Answer:
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
+ + +
---------------------------------
1 13 40 7 ← remainder
quotient = x² + 13x + 40
Thus
[tex]\frac{x^3+8x^2-25x-193}{x-5}[/tex] = x² + 13x + 40 + [tex]\frac{7}{x-5}[/tex]

-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.

On a coordinate plane, a graph of a floor function has horizontal segments that are each 1 unit long. The left end of each segment is a closed circle. The right end of each segment is an open circle. The left-most segment goes from (negative 5, negative 5) to (negative 4, negative 5). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (5, 5) to (6, 5).
Use the graph of the floor function to complete the statements.

Question b : Find ;
the values of
1.alpha³+beta³ and 1/(alpha³) +1/(beta³)
2. the the equation whose roots are alpha³ and beta ³
9514 1404 393
Answer:
(a) 2, 6
(b) 155/8, -155, 8x² -155x -1 = 0
Step-by-step explanation:
(a) The equation in standard form is ...
x^2 -(4+k)x +4k +1 = 0
Then the discriminant is ...
(4+k)^2 -4(1)(4k+1) = 4^2 +8k +k^2 -16k -4 = k^2 -8k +12 = (k -2)(k -6)
The roots are equal when the discriminant is zero. The values of k that make the discriminant be zero are k=2 and k=6.
__
(b) a^3 + b^3 = (a +b)(a^2 -ab +b^2) = (a+b)((a+b)^2 -3ab)
= (5/2)((5/2)^2 -3(-1/2)) = (5/2)(25/4 +3/2) = 155/8 = α³ +β³
1/a^3 +1/b^3 = (a^3 +b^3)/(ab)^3 = (155/8)/(-1/2)^3 = -155 = 1/α³ +1/β³
The desired equation can be written from ...
(x -a^3)(x -b^3) = 0
x^2 -(a^3 +b^3)x +(ab)^3 = 0
x^2 -155/8x -1/8 = 0 . . . . .substituting known values
8x^2 -155x -1 = 0

What is the solution to the equation 4x + 8= -2 - 2 + 5x
Have?
Two
One
None
Invinitely many
Answer:
one solution
Step-by-step explanation:
4x + 8 = -2 -2 + 5x
4x + 8 = -4 + 5x
4x - 4x + 8 = -4 + 5x - 4x
8 = -4 + 5x - 4x
8 = -4 + x
8 + 4 = -4 + 4 + x
12 = x

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.
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
Sunny's Surf Shop sold 160 surfboards this week, which was 320 percent of the number of surfboards sold last week. How many surfboards did Sunny's Surf Shop sell last week? O 16 O 50 O 160 512
Let, the number of Surfboards sold last week = x
Then, x * 320% = 160
x * 3.20 = 160
x = 160/3.20
x = 50
In short, Your Answer would be Option B
Hope this helps!
(no need to give brainliest) :)
Answer:
