Which equation has the greatest rate of change?
y=12x-7
y=5x+9
y=4x+12
y=X+36
Answer:
y=12x-7
Step-by-step explanation:
Rate of change is the same thing as slope which can be found by looking at the value before the x. Since 12 is the largest number, it has the largest rate of change.
What is the area, in square meters, of the circle? Use 3.14 for π. Round your answer to the nearest tenth.
Answer: See explanation
Step-by-step explanation:
You didn't give any figures but let me try and help out.
The area of a circle is given as:
= πr²
Let's say we have radius as 8m, the are will be:
= πr²
= 3.14 × 8²
= 3.14 × 64
= 200.96m²

Answer:
30
Step-by-step explanation:
Answer:
1.) B.) 30
2.) D.) 2.38
Step-by-step explanation:
1.) The answer is B because when the encyclopedia first went live there were 30 articles in it.
2.) The answer is D because the product first started out as $38⁰⁰ and each year it is decreasing half the amount of the year before it and it does this for 4 years:
Start: Year 1: Year 2: Year 3: Year 4:
$38⁰⁰ ÷ 2 = $19 ÷ 2 = $9⁵⁰ ÷ 2 = $4⁷⁵ ÷ 2 = $2³⁸ <--- I rounded up because 2.375 is closer to 2.38

5t+8=13
5t=
Subtract 8 from both sides
t=
Divide both sides by 5
Answer:
t = 1
Step-by-step explanation:
5t + 8 = 13
Subtract 8 from both sides
5t + 8 - 8 = 13 - 8
5t = 5
Divide both sides by 5
5t/5 = 5/5
t = 1
Check:
5t + 8 = 13
5(1) + 8 = 13
5 + 8 = 13

Courtney and Chelsea are leading a family hike on Saturday. The number of snacks Chelsea is bringing can be represented by 2x. Courtney is bringing a number of snacks. If Chelsea brought 16 snacks, how many did Courtney bring?
Answer:
Courtney is bringing 8 snacks
Step-by-step explanation:
Chelsea's snacks are represented as 2x.
2x means 2 · (a number)
If Chelsea brought 16 snacks and the amount of snacks represented by 2x, we have to figure out what times 2 equals 16.
In order to find out, we have to divide.
16 ÷ 8 = 2
This means 2 · 8 = 16
Since the amount of snacks Courtney brings is represented as "x", she would have brought 8 snacks.
Hope this helped! :)
Beth normally cycles a total distance of 56 miles per week.
She increases her distance by 15% each week for the next three weeks.
How many miles will she cycle in the third week?
(3 marks)
miles
Answer:
She will cycle 85.169 miles in the third week.
(round if needed)
Step-by-step explanation:
56÷100=0.56 (this is 1%)
0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)
repeat for the other 3 weeks
64.4÷100=0.644
0.644 x 15 + 64.4 = 74.06
74.06÷100=0.7406
0.7406 x 15 + 74.06 = 85.169
Beth will cycle a distance of 85.169 miles in the third week.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If john obtained a score of 57% on his exam, that corresponds to 57 out of 100.
Beth rides her cycle 56 kilometers each week on average.
For the next three weeks, she will increase her distance by 15% each week.
As per the given condition, the required solution would be as
⇒ 56 / 100 = 0.56
⇒ 0.56 × 15 + 56 = 64.4
If we obtain 15%, add 56 (the initial amount) because there is a 15% increase.
Repeat for the remaining three weeks.
⇒ 64.4 / 100 = 0.644
⇒ 0.644 × 15 + 64.4 = 74.06
⇒ 74.06 / 100 = 0.7406
⇒ 0.7406 × 15 + 74.06 = 85.169
Therefore, she will cycle a distance of 85.169 miles in the third week.

volume of a cylinder
Answer:
A
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the base radius and h the height )
Here r = 6 and h = 8, then
V = π × 6² × 8 = π × 36 × 8 = 288π cm³ → A
Find the equation of the line use exact numbers
Y=_x+_
Answer:
Y = 2x + 4
Step-by-step explanation:
y= mx +b
First, find m (aka the slope)
[tex]\frac{rise}{run}[/tex] = [tex]\frac{2}{1}[/tex] = 2
m = 2
Find b (aka the y-intercept)
The line touches the y-axis at (0,4). Therefore b = 4
Plug m and b into the slope-intercept equation
y = mx +b
y = 2x + 4

-18.18 = 6t
Question 1 options:
t= -24.18
t= -3.03
t= 3.03
t= -13.18
Answer:
-3.03
Step-by-step explanation:
divide -18.18 by 6
Answer:
t= -3.03
Step-by-step explanation:
In order to solve for t, we need to isolate it. We would do this by dividing both sides by 6:
[tex]t= -18.18/6[/tex]
Therefore t= -3.03

Answer:
1. Angle Relationship: Alternate Exterior Angles
2. Angle Relationship: Same side Interior angles
3. Angle Relationship: Corresponding angles
Step-by-step explanation:
Alternate Exterior Angles are angles that are outside of the parallel lines and are opposite of each other.
Same side Interior angles are angles that are inside the parallel lines and are on the same side of a transversal.
Corresponding angles are angles that are in the same matching corners.

Stephen purchased a guitar, which was originally priced at $80 but
discounted at 25%. He also had to pay 5% sales tax. What amount did
Stephen pay to purchase the guitar? *
Answer:
57 dollars
Step-by-step explanation:
1. Solving the 25% discount
25% = .25
80 x .25 = $20
80 - 20 = $60
** We subtracted 80 from 20 because 25% of 80 is 20 BUT We're taking 25% OFF of 80 because it was a discount.
2. Solving the 5% Tax
5% = .05
$60 x .05 = 3
$60 + 3 = $63
**Adding tax to the discounted price
I hope this helps!

Answer: -2
Step-by-step explanation:
Answer:
You have to write the number-line out man. However, the answer is -2
Step-by-step explanation:
When solving problems like these, knowledge or integers and whole numbers are important. First, find the absolute values of both numbers.
Absolute value of -6: 6
Absolute value of 4: 4
Subtract the values: 6 - 4 = (Positive 2)
THEN, look at the number with the Greater Absolute value. In this case, it is -6. Because -6 has the greater absolute value, your answer should be the connotation of that number. IN THIS CASE, the number with the greater absolute value, -6, has a negative sign. Therefore, your answer should be negative. Your answer is -2.

Calculate 48 x 3/8 choose the numbers to complete the equation
Answer:
1. Choose: 3
2. Choose: 144
3. Choose: 18
Step-by-step explanation:
The first thing you do is multiply 48 * 3/8= 18. Then multiply 48 * 1/8= 6. Then divide both answers to get 3, so 48 * 1/8 * 3.
Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).
Finally, to find the third Choose option, you divide the fraction 144/8 = 18.
