Answer:
The ratio is 3:8
Step-by-step explanation:
The circumference of a circle can be calculated using the formula;
C = 2 * pi * r
for 9 inches;
C = 2 * pi * 9 = 18 pi inches
For 24 inches;
C = 2 * pi * 24 = 24 pi inches
The ratio is thus;
18 pi : 48 pi
divide through by 6 pi
= 3: 8

Isaac had lots of candy. He ate the same number of pieces each day, and the amount remaining can be modeled by the equation y = -5x + 83.
what is the meaning of the slope?
What is the meaning of the y-intercept?
How many pieces will he have after 6 days?
When will he have 28 pieces?
Answer:
1. he eats 5 per day (5 less every day)
2. he starts with 83 pieces of candy
3. 53
4. on day 11
Step-by-step explanation:
1. self explanatory
2. self explanatory
3. 6*-5=-30 -30+83=53
4. put y as 28
28=-5x + 83 now solve for x
subtract 83 both sides
-55=-5x
divide -5 from both sides
11=x

Find the length of AB-
A. 16
B. 18
C. 22
D. 32
Answer:
Option (B)
Step-by-step explanation:
From the figure attached,
ΔBCD and ΔACE are the similar triangles.
Therefore, by the property of similar triangles, corresponding sides of these similar triangles will be proportional.
[tex]\frac{AC}{BC}= \frac{EC}{DC}[/tex]
[tex]\frac{AB+BC}{BC}= \frac{ED+DC}{DC}[/tex]
[tex]\frac{AB+6}{6}= \frac{24+8}{8}[/tex]
[tex]\frac{AB+6}{6}= \frac{32}{8}[/tex]
[tex]\frac{AB+6}{6}=4[/tex]
AB + 6 = 24
AB = 18
Option (B) will be the answer.
Celine ate brunch at a restaurant. The bill came to $72.80. If she left a 15% tip, what was the total cost of her brunch?
Answer:
$83.69
Step-by-step explanation:
Given the following
Initial Cost of the brunch = $72.80
Percentage tip = 15%
Tip paid = 15% of $72.60
Tip paid = 0.15 * 72.60
Tip paid = $10.89
Total cost of brunch = $72.80 + $10.89
Total cost of brunch = $83.69
Hence the total cost of her brunch is $83.69

Pip and Sara win some money and share it in ratio 5:4 pip gets £50 how much did they get all together
Answer: £90
Step-by-step explanation:
Pip and Sara get some money. They share it in the ratio 5 : 4.
Pip gets £50 so what did Sara get:
Use direct proportion:
5 : 4
50 : x
5x = 200
x = 200/5
x = £40
Pip got £50 and Sara got £40.
Together they got:
= 50 + 40
= £90

1+y=-4/5x-2
Given that,
The equation is : 1+y=-4/5x-2
To find,
The slope of the line.
Solution,
We have,
[tex]1+y=\dfrac{-4x}{5}-2[/tex]
Subtract 1 from both sides.
[tex]1+y-1=\dfrac{-4x}{5}-2-1\\\\y=\dfrac{-4x}{5}-3[/tex] .....(2)
The general equation of line is :
[tex]y=mx+c[/tex] ...(1)
where m is slope and c is y-intercept
Comparing equation (1) and (2)
m = [tex]\dfrac{-4}{5}[/tex] and c = -3
Hence, the slope of the line is [tex]\dfrac{-4}{5}[/tex].

Ballio's family traveled 3 10 of the distance to his aunt's house on Saturday. They traveled 4 7 of the remaining distance on Sunday. What fraction of the total distance to his aunt's house was traveled on Sunday?
Complete Question
Ballio's family traveled 3/10 of the distance to his aunt's house on Saturday. They traveled 4/7 of the remaining distance on Sunday. What fraction of the total distance to his aunt's house was traveled on Sunday?
Answer:
4/10
Step-by-step explanation:
Let us represent, the total distance travelled as:
1
Ballio's family traveled 3/10 of the distance to his aunt's house on Saturday.
Distance left to travel = 1 - 3/10
= 7/10
They traveled 4 /7 of the remaining distance on Sunday.
The fraction of the total distance to his aunt's house was traveled on Sunday is calculated as:
4/7 × Distance left to travel
= 4/7 × 7/10
= 4/10
Which of the following is the slope of the line that passes through the points (–3, 13) and (5, –7)?
The slope of the line that passes through the points (- 3, 13) and (5, - 7) will be 3/4.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (- 3, 13) and (5, - 7).
Now,
Since, Two points on the line are (- 3, 13) and (5, - 7).
Hence, The slope of the line that passes through the points (- 3, 13) and (5, - 7) is,
⇒ m = (y₂ - y₁) / (x₂ - x₁)
⇒ m = (- 7 - (-13)) / (5 - (-3))
⇒ m = 6/8
⇒ m = 3/4
Thus, The slope of the line that passes through the points (- 3, 13) and
(5, - 7) is,
⇒ m = 3/4

SOMEONE PLZ HELP ME I BEG OF YOU
Answer:
a = $19.70
Step-by-step explanation:
Since she bought 12 student tickets and each costs 10.25, then she spent 12 * 10.25 = $123
That means that the total cost of the adult tickets was $359.40 - $123 = $236.40
The last step is to do $236.40 divided by 12 to find the price per ticket
$236.4 / 12 = $19.70

On Monday the Pied Piper caught 1000 rats in a city.
On Tuesday he caught 10% fewer rats than on Monday.
On Wednesday he caught 20% more than on Tuesday.
On Thursday he caught 30% fewer than on Wednesday.
On Friday he rested.
How many rats did he catch in total that week?
Answer:
3124
Step-by-step explanation:
1000 rats caught on Monday. 10% of 1000 is 100 so, 1000-100=900 so 900 rats caught on Tuesday. 20% of 900 is 180 so, 900-180=720 so 720 rats caught on Wednesday. 30% of 720 is 216 so, 720-216=504 so 504 rats caught on Thursday. None were caught on Friday.
Add up the numbers and you'll get your answer;
1000+900+720+504= 3124
