. Rama subtracted 7 from thrice the number of marbles she has, and she gets the result as 20.
Complete question :
Rama subtracted 7 from thrice the number of marbles she has, and she gets the result as 20. Find the number of marbles she has
Answer:
9 marbles
Step-by-step explanation:
Let The number of marbles she has = x
3 times the total - 7 = 20
That is ;
3x - 7 = 20
3x = 20 + 7
3x = 27
x = 27/3
x = 9
Number of marbles she has = 9

A researcher took a poll of people in his state. He asked each person if he or she had any pets (Yes or No) and to state his or her political party affiliation (Republican, Democrat, or Other). If the researcher computed a chi square test of independence using the responses, what would the degrees of freedom value be
Answer:
DF = 2
Step-by-step explanation:
Formula for degree of freedom is;
DF = n - 1
Where n is sample size
In this question, political party affiliation could be Republican, Democrat, or Other. Thus, sample size is 3.
DF = 3 - 1
DF = 2
Thus, degree of freedom value would be 2
solve the following quadratic equation by completing the square. if you need to round to the nearest tenth. x² - 20x = -75
for f(x) =4x+1 g(x)=x²-5, find (f•g)(x)
Answer:
(f · g)(x) = 4x³ + x² - 20x - 5
General Formulas and Concepts:
Pre-Algebra
Distributive PropertyAlgebra I
Combining Like TermsExpand by FOIL (First Outside Inside Last)Step-by-step explanation:
Step 1: Define
f(x) = 4x + 1
g(x) = x² - 5
(f · g)(x) is f(x)g(x)
Step 2: Find (f · g)(x)
Substitute: (f · g)(x) = (4x + 1)(x² - 5)Expand [FOIL]: (f · g)(x) = 4x³ - 20x + x² - 5Combine like terms: (f · g)(x) = 4x³ + x² - 20x - 5We know that,
[tex] \Large \underline{\boxed{\sf{ (f . g)(x) = f(x) \times g(x) }}}[/tex]
By substituting values :
[tex] \sf : \implies (f . g)(x) = (4x+1) \times (x^{2} -5)[/tex]
[tex] \sf : \implies (f . g)(x) = 4x(x^{2} -5) +1(x^{2} -5)[/tex]
[tex] \sf : \implies (f . g)(x) = 4x^{3} - 20x + x^{2} -5[/tex]
[tex] \sf : \implies (f . g)(x) = 4x^{3} + x^{2} - 20x -5[/tex]
Hence, answer is :
[tex]\underline{\boxed{\sf{(f . g)(x) = 4x^{3} + x^{2} - 20x - 5}}}[/tex]
What information is needed to determine that the two triangles are congruent be ASA?
Answer:
ASA: If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent. SAS: If any two angles and the included side are the same in both triangles, then the triangles are congruent.
9514 1404 393
Answer:
see below
Step-by-step explanation:
ASA requires two angles and the side that lies between them. The list below is a list of such. (The ends of the segments are the vertices of the angles.)
You are the president of an interior design company. You pay a part-time designer
$200 per week, plus $25 for each completed design. Write an equation to represent this
situation. Use this equation to determine how many completed designs you can have per
week if your weekly design budget is $800?
Answer: 24
Step-by-step explanation:
Okay, so if the part-time designer gets 200 dollars per week, we should subtract 200 by 800.
800 - 200 = 600.
Then we divide 600 by 25, and that will be the amount of completed designs we'll be able to have each week.
600 ÷ 25 = 24.
So in conclusion, you can pay the designer $200 per week and get 24 completed designs from him.
Hope this helps!

Im really confused bc ive tried everything and i cant figure this out
-3 7/10 = -3/-4y
its a rational equation
Answer:
y = - [tex]\frac{15}{74}[/tex]
Step-by-step explanation:
Given
- 3 [tex]\frac{7}{10}[/tex] = [tex]\frac{-3}{-4}[/tex] y = [tex]\frac{3}{4}[/tex] y ( change the mixed number to an improper fraction )
- [tex]\frac{37}{10}[/tex] = [tex]\frac{3}{4}[/tex] y
Multiply through by 20 ( the LCM of 10 and 4 )
- 74 = 15y ( divide both sides by 15 )
- [tex]\frac{74}{15}[/tex] = y
Victoria buys 5 scarves for a total of 36.25. If each scarf costs the same amount of money, how much did one scarf cost?
Answer:
7.25
Step-by-step explanation:
36.25/5=7.25 simple
Step-by-step explanation:
cost of 5 scarf = 36.25
cost of one scarf = 36.25/5
= 725/100
= 7.25 $
so one scarf cost = 7.25$

Answer:
BH = 16
Step-by-step explanation:
The centroid theorem states that the centroid of a triangle is 2/3 of the distance from a vertex to the midpoint of the opposite side.
That means that BH is 2/3 of the length BF.
BH = (2/3)(BF)
BH = (2/3)(24)
BH = 16

Answer:
(6x - 1) • (2x + 9)
Step-by-step explanation:
STEP
1
:
Equation at the end of step 1
((22•3x2) + 52x) - 9
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 12x2+52x-9
The first term is, 12x2 its coefficient is 12 .
The middle term is, +52x its coefficient is 52 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 12 • -9 = -108
Step-2 : Find two factors of -108 whose sum equals the coefficient of the middle term, which is 52 .
-108 + 1 = -107
-54 + 2 = -52
-36 + 3 = -33
-27 + 4 = -23
-18 + 6 = -12
-12 + 9 = -3
-9 + 12 = 3
-6 + 18 = 12
-4 + 27 = 23
-3 + 36 = 33
-2 + 54 = 52 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -2 and 54
12x2 - 2x + 54x - 9
Step-4 : Add up the first 2 terms, pulling out like factors :
2x • (6x-1)
Add up the last 2 terms, pulling out common factors :
9 • (6x-1)
Step-5 : Add up the four terms of step 4 :
(2x+9) • (6x-1)
Which is the desired factorization
