Answer:
13
Step-by-step explanation:
for example, Sum of 5 no. = 7×5=35
Sum of 8 no. = 8.5×8=68
Sum of added all three no. = 68 - 35 = 33
average of three new numbers = 33/3=11
The number 25 is added then the average becomes 10.
What is an average?The average is defined as the ratio of the sum of the data to the total numbers of the data.
Average = ( Sum of the numbers ) / ( number of the data )
Given that the average of 5 numbers is 7. when one more number is added the average becomes 10.
The number added is calculated as:-
Sum of the numbers = 5 x 7 = 35
Let x is the number added.
Sum of the numbers = 35 + x
We know that some of the numbers = 10 x 6
35 + x = 10 x 6
35 + x = 60
x = 60 - 35
x = 25
Hence, the number added is 25.

Carmen had
of a spool of yarn. She used
of her yarn for a project. What fraction of the spool was used for the project?
Write your answer in simplest form.
it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.

It costs Eduardo 2 d 3 dollars to go to the carnival for d days. How many dollars does the carnival cost if Eduardo goes for d 5 days?
Answer:
$250
Step-by-step explanation:
Given: Cost for d days carnival = $2d^3 .....(i)
where d is number of days
Now we have to calculate the total cost incured for 5 days of carnival
we can simply put d = 5 in above equation (i)
= 2×5^3 = 2×125 = $250.
Therefore carnival cost if Eduardo goes for d 5 days = $250

Step-by-step explanation:
The hypotenuse is the longest side of a triangle.
You could either add a point at (3,2) or (6,9) to make a right triangle and get the same answer, but for the sake of looking at it right-side-up, I'd use (3,2).
Now, you can use the distance vertically (y coordinate) from the top point to the bottom point ( 9 to 2 ) as your first side length. 9-2= 7, so 7 is that side length.
Then, you can use the distance horizontally (x coordinate) from the bottom left point (3,2) to the bottom right point (6,2). 6-3= 3, so 3 is that side length.
Now for the Pythagorean Theorem (a^2 + b^2 =c^2)

A soccer ball is kicked from the ground with an initial upward velocity of 64 meters per second, and the height of the ball can be represented by the equation h = -16t^2 + 64t. After how many seconds will the ball hit the ground?
Answer:
t = 2 seconds
Step-by-step explanation:
Given that,
h = -16[tex]t^{2}[/tex] + 64 t
where h and t have their usual meaning.
To determine the number of seconds required of the ball to hit the ground, differentiate the given equation with respect to t.
0 = -32 + 64
So that,
32t = 64
t = [tex]\frac{64}{32}[/tex]
t = 2
The ball will hit the ground in 2 seconds.
What is the Volume of the hemisphere ? I will give BRAINLIEST
Answer:
8579 mm^3
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)(pi)(r)^3, where r is the radius.
Here the radius is (appears to be) 16 mm.
Thus, the radius of this sphere is V = (4/3)(pi)(16 mm)^3, or 28268 mm^3.
But we want the volume of the hemisphere (half sphere). Thus,
divide the above result by 2:
The volume of this hemisphere is 8579 mm^3
Answer:
8.582
Step-by-step explanation:
volume of hemisphere is 2 / 3 π r^3
2/3 πr^3
π is 22/7
r is 1.6 mm
2/3 × 22/7 × 1.6^3 = 8.582 to 3 decimal places

Answer:
A 2 ounce bag costs $1.2.
Step-by-step explanation:
With the information provided, you can use a role of three to find the cost of a 2 ounce bag given that you know that a six ounce bag costs $3.60.
6 ounce bag → 3.60
2 ounce bag → x
x=(2*3.60)/6
x=7.20/6
x=1.2
According to this, the answer is that a 2 ounce bag costs $1.2.

Roy hit 3 less than 4 times the number of balls during baseball practice than Joe did. Together the boys hit 52 balls. How many balls did Joe hit?
Answer:
Joe hit 11 balls Roy hit 41
Step-by-step explanation
Joe = J
Roy = 4J-3 (4times Joe less 3)
J+ 4J-3 = 52
5J -3 = 52
Add 3 on both sides
5J = 55
Divide both sides by 5
J= 11
Joe = 11
11X4 = 44
44-3 = 41
Roy 41
11+41 = 52
