Which is a better buy? 3 candy bars for $0.30 each or 3 candy bars for $1.50?
Answer:
3 candy bars for 0.30
Step-by-step explanation:
The same amount of bars for less is the better buy
Answer:
3 candy bars for $0.30 each is the better buy
Step-by-step explanation:
We must do the math to find out how much 3 candy bars will cost for 30 cents each.
0.30 x 3 = 0.90
Therefore, three candy bars cost 90 cents. 90 cents is less than a dollar and 50 cents. Therefore, the 3 candy bars for $0.30 each is the better deal.

I need help solving A (ignore B and C, I have them solved already). I'm just a little confused on A. I need to find the measure of X and Y
Answer:
x = -113
y = 30
Step-by-step explanation:
110+10+2y=180
2y=180-110-10
=60
y=60/2
y=60/2 =30
-3x-10-2x+15+110+120+95=540
-3x-2x =540+10-15-110-120-95
-5x=210
x=210/-5
x=210/-5 = - 42
Step-by-step explanation:
Here,
110+2y+10=180°(being sum of angles in
a straight line)
y=180-120
y=60°,,
now,
to find the value of X,
120+95+110+3x-10+2x+15=540°(being sum of all angle of pentagon)
330+5x=540°
5x=540-330
5x=210
X=210/5
x=42°,,
The teacher is handing out note cards to her students. She gave 2 note cards to the first student, 6 note cards to the second student, 18 note cards to the third student, and 54 note cards to the fourth student. If this pattern continues, how many note cards will the teacher give to the fifth student?
Answer:
162 because if you multiply all of them by 4 you get the answer
The teacher will give 162 note cards to the fifth student.

A young equestrian loved to ride her horse all day long, dreaming of the day
she would ride in the Kentucky Derby. One day in early April, she left home at
10:00 am and rode her stallion at a nice, steady 10 miles per hour away from
her house. At noon a call came in from the Derby saying she was in! Her
father immediately jumped on his scooter and rides at a breezy 15 miles per
hour to try and track her down and tell her the good news.
On what scale would you measure the number of minutes the father must
ride his scooter before catching up to his daughter?
O
A. Ten thousands
O
B. Thousands
O
c. Tens
O
D. Hundreds
Answer:
Hundreds
Step-by-step explanation:
Given that :
Daughter rode out at 10:00 am
Speed = 10 miles per hour
Father rode out at 12:00 noon
Speed = 15 miles per hour
Distance = speed * time
Daughter's distance before father rode out = (10 * (12:00 - 10:00))
= 10 * 2
= 20 miles
Difference in speed (father - daughter) :
15mph - 10mph = 5mph
Time which father will catch up with her :
Time = distance / speed
Time = 20 miles / 5 mph
Time = 4 hours
In minutes ; 4 * 60 = 240 minutes
Highest place value of minutes = hundreds
Two whole numbers have a least common multiple of 60. -Each number is less than or equal to 12. -The greatest common factor of the two numbers is 2. What are the two numbers?
Answer:
The two number are 10 and 12
Step-by-step explanation:
Two whole numbers have a least common multiple of 60.
We are told that:
-Each number is less than or equal to 12.
The first thing we know is that: one of that two number is 12
The next step would be to find the factors of 60
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 60 that is equal to or less than 12 is
1, 2, 3, 4, 5, 6, 10, 12
We would find which of these number that has the greatest common factor of 2 with 12
The factors of 10 are: 1, 2, 5, 10
The factors of 12 are: 1, 2, 3, 4, 6, 12
Then the greatest common factor is 2...
Also calculating the least common factor of 10 and 12
Multiples of 10:
10, 20, 30, 40, 50, 60, 70, 80
Multiples of 12:
12, 24, 36, 48, 60, 72, 84
Therefore,
LCM(10, 12) = 60
Therefore, two numbers with the least common multiple of 2 and greatest common factor of 60 is 10 and 12

2(2z– 3) = 18
Please help I will mark brainliest answer please help
Answer:
z=6
Step-by-step explanation:
2(2z−3)=18
Divide each term by 2 and simplify.
2z−3=9
Move all terms not containing z to the right side of the equation.
2z=12
Divide each term by 2 and simplify.
z=6
Hope this helps! :) Plz mark as brainliest!
Answer:
z =6
Step-by-step explanation:
so we simplify from both side.
2( 2z - 3) = 18
*2 *2
4z - 6 = 18
+ 6 +6
4z = 24
then we divide both sides from 4
4z / 4 = 24/ 4
z = 6
The sum of 3 numbers in an ap is -3 and their product is 24 find the number
• Sum of three numbers in an AP is -3
• Their product is 24.
To find :• The numbers .
Solution:Let the numbers be .
• (a-d) , a , (a+d) .
A/Q ,
• Sum of numbers = -3
=> a-d + a + a+d = -3
=> 3a= -3
=> a = -1 .
Now ,
• Product of numbers = 24
=>( a-d)(a)(a+d)= 24
=> (a²- d²) (a) = 24
=> (1- d²)(-1)=24
=> -1+d²= 24
=> d²= 25
=> d = ±5.
If d = 5 the numbers are :
• a+d , a , a-d = 4 , -1 , -6
If d = -5 the numbers are :
• a+d , a , a -d = -6, -1 , 4 .
The numbers are :
4 , -1 , -6 and -6, -1,4

Graph x > 5
Circle would be
a. open
b. closed
Arrow would be pointed
c. left
d. right
Answer:
a., d
Step-by-step explanation:
An open circle on a number does not include the number that has the circle. A closed circle includes the number that has the circle.
An arrow pointing to the right includes numbers that are greater than the number that has the circle. An arrow pointing to the left includes numbers that are less than the number that has the circle.
The equation is x > 5.
That means that 5 is not included, and all numbers greater than 5 are included.
5 not included: Use an open circle.
Numbers greater than 5: arrow point to the right.

This is actually very simple!
If Talia makes 2 mistakes every 3 minutes then the ratio is 2:3
Going along with that if you know how ratios work then that should be easy. But this is also the long way. You dont really need to know ratios you just need to know the steps but knowing ratios would be helpful.
You first divide
18 / 3 = 6
Then multiply
6 x 2 = 12
That's it!

Emma bought 17 packages of rolls for a party. There were 18 rolls in a package. After the party there were 8 rolls left over. How many roles were Eaten
Answer:
298 rolls
Step-by-step explanation:
As per the above, we were given that Emma bought 17 packages of rolls.
We need to find the number of rolls in the packages that he bought, hence
Total rolls = 17 packages × 18 rolls per package
= 306 rolls
Furthermore, since we have 8 rolls leftover, then total number of rolls eaten would be;
Rolls eaten = Total number of rolls in the beginning - rolls leftover
= 306 - 8
= 298 rolls
It therefore means that 298 rolls were eaten by Emma.
3.25 round to the nearest whole number
Answer:
3.25 round to the nearest whole number is 3
Step-by-step explanation:
The solution of the 3.25 when rounded off to the nearest whole number according to the rule of rounding numbers is 3.
Rounding off numbers means adjusting a number simpler by adjusting it to its nearest place according to certain rules.
In rounding off numbers, the place value starts from tens place.
Rounding to the nearest whole number: Look at the digit immediately to the right of the decimal point. If it is 5 or greater, round the number up. If it is less than 5, round the number down.
As per the given question,
Rounding 3.25 to the nearest whole number we look at the digit immediately to the right of the decimal point though it is less than 5 so, the number gives 3, according to the rule of Rounding numbers.
The solution of the 3.25 when rounded off to the nearest whole number is 3.

Find the sum of the interior angle measures of a convex 20-gon (a twenty-sided polygon).
Answer:
3,240°
Step-by-step explanation:
Sum of interior angles of n-sided polygon is given as (n - 2)180. Where n = number of sides of the polygon.
Sum of angles of a convex 20-gon = (20 - 2)180
= (18)180 = 3,240°
Sum of interior angles of a convex 20-gon = 3,240°
Answer:
3,240
Step-by-step explanation:
(n-2)180 n is the number of sides
Substitute 20 for n, then simplify
(20 - 2)180 = (18)180 = 3,240
