At the beginning of spring, Anthony planted a small sunflower in his backyard. When it was first planted, the sunflower was 20 inches tall. The sunflower then began to grow at a rate of 1.5 inches per week. How tall would the sunflower be after 6 weeks? How tall would the sunflower be after ww weeks?
Answer: The sunflower be 50 inches tall after 6 weeks.
Total height of sunflower in w weeks = 20+1.5 w,
Step-by-step explanation:
Given: In the beginning, the sunflower was 20 inches tall.
The sunflower then began to grow at a rate of 1.5 inches per week.
Then, total height of sunflower in 6 weeks = 20+1.5 ×20, where 1.5 ×20= growth in 6 weeks
= 20+30
= 50 inches
So, the sunflower be 50 inches tall after 6 weeks.
Let w = number of weeks, then
Total height of sunflower in w weeks = 20+1.5 w, where 1.5 w= growth in w weeks.
Answer: 29

Answer:
x = 12
Step-by-step explanation:
Move numbers and variables on opposite sides and flip the signs
9x - 4x = 20 + 40
Add and subtract
5x = 60
Divide and multiply
x = 60/5
x = 12
Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator
24 min to 64 min
Answer: 3/8
Step-by-step explanation:
24 min to 64 min as a fraction is [tex]\frac{24}{64}[/tex]
Now write the fraction is simplest form by dividing it by their greatest factor.
The GCF of 24 and 64 is 8
24/8 = 3
64 /8 = 8
So the ratio will be 3/8
Which value is equivalent to 7 x 5 x 2 divided by 7 x 3 to the 2nd power x 5 to the 0 power divided by 2 to the negative 3rd power x 2 to the negative 9 power
Answer:
This is hard to read, but i guess that the equation is:
[tex]7*5*2/7*3^2*5^0/2^{-3}*2^{-9}[/tex]
So we have some things to solve:
First, for any number:
x^0 = 1
then 5^0 = 1.
And for negative powers,
x^-n = (1/x)^n.
And we
Then we can rewrite our equation as:
[tex]\frac{7*5*2*3^2*1*2^3}{7*2^9}[/tex]
now we can cancel the seven in the numerator and the denominator
[tex]\frac{5*2*3*2^3}{2^9}[/tex]
now, remember the relation:
a^x*a^y = a^(x+y)
then:
2*2^3 = 2^4
and 2^4/2^9 = 2^-5 = (1^2)^5
Then our equation is:
[tex]\frac{5*3}{2^5}[/tex]
15/2^5 = 0.46875

On Gabriela’s first birthday, her parents gave her a $50 savings account. On every birthday after that her parents added to the account, increasing the amount they deposited by $25 each year. Complete the recursive definition for the sequence that represents this situation by finding the values for a1 and d. Calculate the total amount Gabriela’s parents will have deposited into the account on her birthdays by her 18th birthday.
Answer: [tex]a_1=50,d=25[/tex] and $475 deposited into the account on her birthdays by her 18th birthday.
Step-by-step explanation:
It is given that, on Gabriela’s first birthday, her parents gave her a $50 savings account.
Initial term : [tex]a_1=50[/tex]
On every birthday after that her parents added to the account, increasing the amount they deposited by $25 each year.
Common difference : [tex]d=25[/tex]
It forms an AP: 50,75,100,...
nth term of an AP is
[tex]a_n=a_1+(n-1)d[/tex]
Substitute [tex]a_1=50[/tex] and [tex]d=25[/tex] in the above formula.
[tex]a_n=50+(n-1)25[/tex]
It represents the amount deposited into the account after n birthdays.
We need to find the amount by her 18th birthday.
Put n=18 in the above equation.
[tex]a_{18}=50+(18-1)25[/tex]
[tex]a_{18}=50+(17)25[/tex]
[tex]a_{18}=50+425[/tex]
[tex]a_{18}=475[/tex]
Therefore, $475 deposited into the account on her birthdays by her 18th birthday.
We are to calculate total amount given to Gabriela on her 18th birthday
Total amount Gabriela’s parents will have deposited into the account on her birthdays by her 18th birthday is $475
Amount given to her on her first birthday = $50
Additional amount given to her each year = $25
number of years, n = 18
a1 = $50
d = $25
n = 18
Sum = a1 + (n - 1)d
= 50 + (18 - 1)25
= 50 + (17)25
= 50 + 425
= 475
sum = $475

Use the given conditions to write an equation for the line in point-slope form and in slope-intercept form. Passing through -3, -6) and parallel to the line whose equation is y=-4x+1
Step-by-step explanation:
Hey there!
The equation of a st.line passing through point is;
(y + 6) = m1(x+3).........(i). [ Use one point formula]
y = -4x + 1............(ii)
Comparing 2nd equation with y = mx+c, we get;
Slope (m2) = -4.
For parallel lines;
[tex]m1 = m2[/tex]
(i.e m1=m2 = -4)
Putting value of slope in 1st equation,
[tex](y + 6) = - 4(x + 3)[/tex]
Smplify them to get equation.
[tex](y + 6) = - 4x - 12[/tex]
[tex]y = - 4x - 12 - 6[/tex]
[tex]y = - 4x - 18[/tex]
Therefore the required equation is y = -4x-18.

Covert this repeating decimal into a fraction:
3.00121212121212...
-26 - 4m = -2(2m + 13)
Answer:
Your answer would equal the same on the other side.
-26-4m=-4m-26
if you minus 26 from both sides youll have -4m on both sides also. So it would equal. So you have an Equaled equation if that makes sense.
solve x-5/y = z for y
Answer:
y=5x−z
Step-by-step explanation:
Step 1: Multiply both sides by y.
xy−5=yz
Step 2: Add -yz to both sides.
xy−5+−yz=yz+−yz
xy−yz−5=0
Step 3: Add 5 to both sides.
xy−yz−5+5=0+5
xy−yz=5
Step 4: Factor out variable y.
y(x−z)=5
Step 5: Divide both sides by x-z.
y(x−z)x−z=5x−z
y=5x−z

seconds
320
20

3
Answer:
48 metres.
Step-by-step explanation:
How far does the cyclist travel in 3 seconds:
First, find how far the cyclist goes in 1 second:
320 metres = 20 seconds
? = 1 second
320 ÷ 20 = 16 metres
The cyclist travels 16 metres in 1 second.
How far does the cyclist travel in 3 seconds:
1 second = 16 metres
3 seconds = ?
16 × 3 = 48 metres.
The cyclist travels 48 metres in 3 seconds.

Convert the repeating decimal to an improper fraction or mixed number. Include your work in your final answer. \(3.\overline{152}\)
Answer:
Assuming the repetitive part is 152, i.e. the original repeating decimal is
A=3.152152152....
then
1000A=3152.152152152152....
subtract A
1000A-A=3152.152152....-3.152152152....
999A=3149
A=3149/999=3+152/999=3 152/999
Therefore
3.152152152.... = 3149/999 or 3 152/999
