Answer:
The depth of oil in the tin is 9cm
Step-by-step explanation:
The first thing we need to do here is to calculate the volume of the cylindrical tin.
Mathematically, that would be;
V = pi * r^2 * h
now, r = d/2 = 12/2 = 6cm
h = 14 cm
Thus the volume would be;
V = 22/7 * 14 * 6^2 = 1,584 cm^3
Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.
Now let’s say the height of the tin is x, this means its volume which is l * b * h = 16 * 11 * x = 176x
So the depth x would be;
176x = 1584
x = 1584/176 = 9 cm
Solve 10x^2=6+9x

Step-by-step explanation:
Write a phrase for the algebraic expression:
s +7
There are many possible answers for this.
One example is below.
S = the number of stations included when a person orders basic cable, write an expression for the number of stations a person has if he ordered basic cable and 7 premium channels.
We can represent this as s + 7.
The value that we don't know is the number of
stations included when a person orders basic cable.
So we can represent that as s.
Then, since the person ordered 7 premium channels, that means he
is adding an additional 7 channels to his basic cable plan.
So we can represent this as s + 7.
Answer:
a number plus 7
Step-by-step explanation:
s+7
Let s represent an unknown number
a number plus 7

AG is congruent to what? In the picture
Answer:
D
Step-by-step explanation:
If 2 tangents are drawn to a circle from the same external point then they are congruent.
AG and AE are tangents to the circle from the same external point, thus
AG is congruent to AE
AG is congruent to AE. Then the correct option is D.
What is congruency?In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.
If two tangents are drawn to a circle from the same external point then they are congruent.AG and AE are tangents to the circle from the same external point.

the average newborn baby weighs 7.9 lbs with standard deviation of approximately 0.5lbs. if this is normal distribution then what percentage of babies would be at least 9.4 lbs.
Answer:
99.87%
Step-by-step explanation:
We would be using the Z score formula to solve this question. The formula is given as:
z = (x-μ)/σ,
Where :
x = observed value = 9.4lbs
μ = mean or average value = 7.9lbs
σ = Standard deviation = 0.5lbs
z = (9.4- 7.9)/0.5
z = 3
The z score = 3
Using the normal distribution table to find which percentage of babies would be at least 9.4lbs
P(x<Z) = 0.99865
Converting this to percentage = 0.99865 × 100 = 99.865%
Approximately = 99.87%
Therefore, the percentage of babies would be at least 9.4 lbs = 99.87%

Answer:
2,172
Step-by-step explanation:
not too sure sorry
Answer:
184
Step-by-step explanation:
y + j + p + a = 1026
y - 60 = j/4 -------> y = (j/4) + 60
p + 150 = j/2 -----> p = (j/2) - 150
2a = j -------> a = j/2
y = ?
y + p + j + a = 1026
(j/4) + 60 + (j/2) - 150 + j + (j/2) = 1026
(j/4) + j + j - 90 = 1026
(j/4) + 2j = 1116
9j/4 = 1116
9j = 4464
j = 496
y = (496/4) + 60 = 184

The upper-left coordinates on a rectangle are (-8,8)(−8,8)left parenthesis, minus, 8, comma, 8, right parenthesis, and the upper-right coordinates are (-3,8)(−3,8)left parenthesis, minus, 3, comma, 8, right parenthesis. The rectangle has an area of 151515 square units.
Draw the rectangle on the coordinate plane below.
Answer:
The other two co-ordinates are (-3, 5) and (-8, 5).
Step-by-step explanation:
Consider the rectangle ABCD.
A = upper-left coordinates = (-8, 8)
B = upper-right coordinates = (-3, 8)
C = lower-left coordinates
D = lower-right coordinates
Let the side AB form the length of the rectangle.
Compute the distance between the points A and B as follows:
[tex]AB=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
[tex]=\sqrt{(-3+8)^{2}+(8-8)^{2}}\\=\sqrt{(5)^{2}}\\=5[/tex]
The length of the rectangle ABCD is 5 units.
The are of ABCD is given as 15 square units.
Compute the breadth of the rectangle as follows:
[tex]\text{Area}=\text{l}\times\text{b}\\15=5\times\text{b}\\b=3[/tex]
So, the breadth of the rectangle is 3 units.
Then from point B, 3 units below would be (-3, 5).
And from point A, 3 units below would be (-8, 5).
The rectangle on the coordinate plane is attached below.

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such as printing). The one-time fixed costs will total $ 31,905 . The variable costs will be $ 8.50 per book. The publisher will sell the finished product to bookstores at a price of $ 19.75 per book. How many books must the publisher produce and sell so that the production costs will equal the money from sales?
Answer:
Step-by-step explanation:
Let x = no. of books
:
Cost = 12.50x + 54150
:
Revenue = 25x
:
Rev = cost
25x = 12.5x + 54150
25x - 12.50x = 54150
12.5x = 54150
x = 54150%2F12.5
x = 4332 books need to be sold to cover production costs
:
:
Check:
c = 12.50(4332) + 54150
c = 54150 + 54150
c = 108300

A has coordinates (1, 7).
Find the coordinates of B.
Answer:
(3,3)
Step-by-step explanation:
Answer:
(3,3)
Step-by-step explanation:

(1+ xb)/2 = 2
1+ xb = 4
xb = 4-1
xb =3
To find the midpoint add the y coordinates together and divide by 2

The width of a rectangle is the length minus 3 units. The area of the rectangle is 10
units. What is the width, in units, of the rectangle?
Answer:
w=2
Step-by-step explanation:
A=length times width (A=lw)
w= l-3
A=10
Substituting in, we get:
10= l(l-3)
Now, solve the equation.
10= [tex]l^{2}[/tex]-3l
[tex]l^{2}[/tex]-3l-10=0
(l+2) (l-5)=0 (factoring the equation)
Therefore, l= -2 or 5
Throw out the negative value because a length of rectangle will never be negative.
Now let's solve for width
Remember w=l-3
therefore
(5)-3=2
so, w=2
(honestly, this is easier to just do in your head. But here is the long form math if you happen to run into more complicated problems.)
Answer:
w=2 l=5

Aaron started at a height of 43 feet in the air. He jumped feet first from the cliff into the water below. The total
distance he traveled was 52 feet. How far underwater did Aaron travel?
Answer:
Aaron travelled about 9 feet underwater
Step-by-step explanation:
We need to work with the information we are given in the question.
there are two stages of Aaron's travel. the first distance was in the air, and the second distance was in the water.
We are given both the total distance travelled and the distance travelled in the air.
To get the distance travelled in water, we subtract the distance travelled in the air from the total distance.
This will be 52 feet - 43 feet = 9 feet
Hence Aaron travelled about 9 feet underwater
