Find the GCF for the list.
98y4. 147y3
Answer:
GCF = 49y³
Step-by-step explanation:
We need to find the GCF of 98y⁴ and 147y³.
Prime factorization of 98y⁴ = 7×7×2×y⁴
Prime factorization of 147y³ = 7×7×3×y³
Common factors are = 7×7y³
= 49y³
Hence, GCF is 49y³

Answer:
40 people
Step-by-step explanation:
you split 40 in half and half of forty is 20. you also have to split 16 in half which is 8. so for every 20 percent there will be 8 people so 8 x 5 is 40 so the answer is forty
A jar contains 770 beans. Of them, 350 are mung beans and the rest are kidney beans. What is the ratio of mung beans to all the beans?
Answer:
5 MB : 16 B
Step-by-step explanation:
First, find the GCF of 770 and 350. ( 70 )
Next, divide both numbers by 70
770 / 70 = 11 Kidney beans
350 / 70 = 5 Mung beans
It says ratio of mung beans to all beans.
11 KB + 5 MB = 16 B
5 Mung beans to 16 Beans

Answer:
Step-by-step explanation:
x² -14x+50= 0
this equation has 2 solutions because is a quadratic
the solurions are imaginary roots because the discriminant is less then 0
b²-4ac = (-14)²-4*1*50 = 194-200= -6
to find the actual roots use the quadratic formula

There are a total of 50 questions worth 130 points on Chenille’s history exam. Some of the questions are worth 5 points each, and the other questions are worth 2 points each. How many 2-point questions are on Chenille’s test?
Answer:
26
Step-by-step explanation:
If there are a total of 50 questions worth 130 points on Chenille’s history exam. There are 24 2-point questions are on Chenille’s test.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, there are a total of 50 questions worth 130 points on Chenille’s history exam. Some of the questions are worth 5 points each, and the other questions are worth 2 points each.
We have to find the 2-point questions on Chenille’s test,
Suppose the number of questions worth 5 points and 2 points will be x and y respectively.
The obtained equation according to the given conditions is,
x+y=50
5x+2y=130
Put the value of y in equation 1 as
5x+250=130
5x=250-130
5x=120
x=24
The value of y will be 26.
Thus, if there are a total of 50 questions worth 130 points on Chenille’s history exam. There are 24 2-point questions are on Chenille’s test.

o 15/64
o 15/16
o 2 2/5
o 2 8/20
thank you!
Answer:
2 2/5
Step-by-step explanation:
3/4 divided by 5/16 = 3/4 times 16/5, which equals 48/20.
4 goes into each.
thus, giving you 12/5.
we write this as a mixed number, which gives us 2 2/5

Answer:
G. [tex] \frac{3.2}{2} = \frac{a}{8} [/tex]
Step-by-step explanation:
Given that figure I and figure II are similar, it follows that the ratio of their corresponding side lengths are equal and the same.
Thus:
[tex] \frac{3.2}{2} = \frac{a}{8} = \frac{8}{5} = \frac{6.4}{b} [/tex]
Therefore, the proportion that must be true is:
✔️[tex] \frac{3.2}{2} = \frac{a}{8} [/tex]
half of the substance to remain is called the half-life of the substance.
The half-life of a pesticide is 10 years. A farmer initially applies 200 grams of the
pesticide to a fence post.
Complete the following statements.
After 20 years, there are
grams of pesticide left. Round your answer
to the nearest whole gram.
After 60 years, there are
grams of pesticide left. Round your answer
to the nearest hundredth of a gram.
After
years, there are approximately 1.03 grams of pesticide
left. Round your answer to the nearest whole year.
Answer:
Instructions are below.
Step-by-step explanation:
To calculate the final amount if a given substance, we need to use the following formula:
final amount= initial amount / (2^n)
n= elapsed time / half-life
For 20 years:
n= 20/10= 2
Final amount= 200/(2^2)
Final amount= 50 grams
For 60 years:
n= 60/10= 6
Final amount= 200/ (2^6)
Final amount= 3.125 grams
To calculate the elapsed time it is more complicated:
elapsed time= ln(ending amount/beginning amount) / (-decay constant)
ln= natural logarithm
decay constant= ln(2) / half-life
decay constant= 0.0693
elapsed time= ln(1.03/200) / (-0.0693)
elapsed time= 76.028
Prove:
n= 76.02/10= 7.602
Final amount= 200/(2^7.602)= 1.03 grams

Solve the equation for the given variable. Justify each step.
9x + 2y = 5; y
Answer:
{x,y}={ 5/9,0}
Step-by-step explanation:
9x - 2y = 5
y = 0
9x - 2•() = 5
9x = 5
x = 5/9
By now we know this much :
x = 5/9
y = 0
⇒{x,y} = {5/9,0}
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]9x + 2y = 5[/tex]
solving the equation for y
[tex]9x + 2y = 5[/tex]
Step 1: Add -9x to both sides
[tex]9x+2y+-9x=5+-9x[/tex]
[tex]2y=-9x+5[/tex]
Step 2: Divide both sides by 2
[tex]\frac{2y}{2}=\:\frac{-9x+5}{2}[/tex]
[tex]y=\frac{-9}{2}x+\frac{5}{2}[/tex]
Thus, the value of y is:
[tex]y=\frac{-9}{2}x+\frac{5}{2}[/tex]
If we put y = 0 in the [tex]9x + 2y = 5[/tex]
[tex]9x+\left(0\right)=5[/tex]
[tex]9x=5[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}9[/tex]
[tex]\frac{9x}{9}=\frac{5}{9}[/tex]
[tex]x=\frac{5}{9}[/tex]
Thus, the value of x=5/9 at y=0
