Answer:
68.55
Step-by-step explanation:
C= 2πr
C=2 x 3.14 x 7.5 = 47.1 (Divide by 2 for half circle)
47.1 ÷ 2 = 23.55 + 15 + 15 + 15 = 68.55

A number when divided by 5 gives 0 as remainder, that number when divided by 7 gives 0 as remainder also. What will be the remainder when that number is divided by 35?
Answer:
zero
Step-by-step explanation:
The computation of the remainder when the number would be divided by 35
Let the number be x
So if x is divided by 5 gives the remainder 0
x = 0
And, if x is divided by 7 gives the remainder 0
x = 0
So if x is divided by 35 so the remainder is also zero

Step-by-step explanation:
H+ ions increase in concentration at lower pH values. Calculate how many more H+ ions there are in a solution at a pH = 2 than in a solution at a pH = 6. Find the concentration of H+ ions at a pH = 2 and at a pH = 6 in Table B. Then divide the concentration of H+ ions at a
pH = 2 by the of H+ ions at a pH = 6. Record your answer in Table C.
What is the concentration of H+ ions at a pH = 2?
mol/L
What is the concentration of H+ ions at a pH = 6?
mol/L
How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?
Answer:
What is the concentration of H+ ions at a pH = 2?
⇒ 0.01 mol/L
What is the concentration of H+ ions at a pH = 6?
⇒ 0.000001 mol/L
How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?
⇒ 10,000
Step-by-step explanation:
Answer:
What is the concentration of H+ ions at a pH = 2?
0.01
What is the concentration of H+ ions at a pH = 6?
0.000001
How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?
10,000

The rate of change is constant in each table. Find the rate of change. Explain what the rate of change means for the situation.
Time (days)
Cost ($)
3
75
4
100
5
125
6
150
A. [tex]\frac{1}{25}[/tex] dollars per day; the cost is $25 for each day.
B. [tex]\frac{75}{1}[/tex] dollars per day; the cost is $75 for each day.
C. [tex]\frac{25}{1}[/tex] dollars per day; the cost is $25 for each day.
D. [tex]\frac{1}{150}[/tex] dollars per day; the costs $1 for 150 days
Answer: C. (25)/(1) dollars per day; the cost is $25 for each day.
$25/ 1 day or $25 a day
Step-by-step explanation:
Answer:
The rate of change is 25. It means the cost increased by $25 per day.
Step-by-step explanation:
The given table is
Time (days) Cost ($)
3 75
4 100
5 125
6 150
It means the graph of this constant function passing through the points (3,75) and (4,100).
If a line passing through two points, then the slope of the line is
Therefore the rate of change is 25. It means the cost increased by $25 per day.

3. Hessa is building a scale model of a park. She uses a scale of 12 cm to represent 1.5 m. a) The actual length of the bridge is 20 m. What is the length of the model bridge? b) In the model, the height of the climbing frame is 10 cm. What is the actual height of the frame?
Answer:
160cm
80cm
Step-by-step explanation:
If 12cm = 1.5m
convert cm to meter
1 meter = 12/1.5 = 8cm
20m = 20m x 8 cm = 160 cm
10cm = 10 x 8 = 80cm

Answer:
224/100 = 2 24/100
= 2 6/25
308/100 = 3 8/100
= 3 2/25
125/1000 = ⅛
444/1000 = 111/250

Answer:
Slope intercept form is y = mx + b
m is slope
b is y intercept
y = -4/5x + -9
I only know that first one sry
Step-by-step explanation:
Answer:
yes.
Step-by-step explanation:
slope intercept form is y=mx+b
b is the y intercept, m is the slope, and x is x.
for
1. it would be
y= -4/5x -9
2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)
it would look like:
(5- -3) / (3-0) = (8/3)
Then plug in one of the sets of numbers for x and y, to get y intercept.
5=8/3(3)+b
b=-3
So.. slope intercept would be y=8/3x -3

The circumference of a circle is m. What is the area , in square meters ? Express your answer in terms of pi
Answer:
area = m²/2π
Step-by-step explanation:
∵ circumference of circle = 2πr = m
∴ r = m/2π
∵ area of circle = πr²
∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π
