A cooler has a 60-L capacity. Its internal length is 60 cm and its internal width is 35 cm. Determine the internal height and the internal surface area of the cooler.
Hint 1 cm^3=1 ml
Answer:
28.5714285714286 cm
Step-by-step explanation:
1 L = 1000 mL
1 L = 1000 cm^3
60 L = 60,000 cm^3 (multiply both sides by 60)
The cooler has volume of 60,000 cubic cm. Let V = 60000
Assuming the cooler is a rectangular prism (aka a block), then we can say
volume = length*width*height
V = L*W*H
60000 = 60*35*H
60000 = 2100H
2100H = 60000
H = 60000/2100
H = 28.5714285714286 which is approximate
And the surface area (SA) is
SA = 2*(LW + LH + WH)
SA = 2*(60*35 + 60*28.5714285714286 + 35*28.5714285714286)
SA = 9628.57142857143 which is also approximate
Units for the surface area are in square centimeters.
The function f(x) is graphed below . What is true about the graph on the interval from point b to point c ?
Answer:
negative and increasing
Step-by-step explanation:
The graph in the interval b to c is below the x- axis and is therefore negative,
from b to c the slope of the curve is positive so it is increasing

Given: ∆DEK, DE = EK
EF − ∠ bisector of ∠E
m∠DEF = 44°
DK = 16
Find: KF
m∠DFE
Answer:
So let me help you!
Step-by-step explanation:
KF = 8 units
m∠DFE = 90°
-
We know that DK is 16 so you would just have to divide it by 2
[tex]\frac{16}{2} =8[/tex]
-
Since EF is a bisector, split it right down the middle means it will be equal to 90 degrees.

What is the y-intercept of the line passing through the point (5,-6) with a slope of - 37 O A. 27 OB. 47 7 OC O c. 47 37 O OD. - 27
Answer:
y=mx+b
Points are in (x,y) form so 5 is x and -6 is y
We know m = -1/7 (because m is slope)
So we can plug these values in to find b.
So:
-6 = 5(-1/7) + b
-6 = (-5/7) + b
-6 + 5/7 = b
b = -37/7
what angle is this? a and b
Answer:
Use protractor to measure B
I think the measure of a is acute angle
5. The corners of triangle PQR lie on a circle. PQ = 3i + 4j and PR = -8i + 6j. By showing that the triangle is right-angled, or otherwise, find the area of the circle. [8]
The formed triangle is not right angled triangle. The area of circle is 19.64 square units.
What is the general equation of a Straight line? State the area of circle? How do we express vectors.The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The area of circle is -
A = πr² = π(d/2)²
A vector is represented by -
A = A[x] i + A[y] j + A[z] k
We have the following problem -
The corners of triangle PQR lie on a circle. PQ = 3i + 4j and PR = -8i + 6j.
|PQ| = 5 units
|PR| = 10
PR + RQ = PQ
RQ = PQ - PR
RQ = 11i - 2j
|RQ| = 11.18
It can be seen that it is not a right angled triangle.
Equation of the diameter of the circle -
y = 4/3x {Assuming it pass through origin}
Diameter length = 5
Radius length = 5/2
Area of circle = 22/7 x 5/2 x 5/2 = 19.64 square units.
Therefore, the formed triangle is not right angled triangle. The area of circle is 19.64 square units.

D. 26
Answer:
A. 8
Step-by-step explanation:
The angle shown is a 90 degree right angle (shown by the box where the vertex is)
We see that the first angle inside the right angle is 50 degrees, so the other angle must be 40 because the degrees must add up. We can set up an equation here.

Answer:
120
Step-by-step explanation:
5 factorial
There are total 120 ways to arrange the letters of word "COUNT".
What is permutation?A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
Permutation Formula[tex]nP_{r} =\frac{n!}{(n-r)!}[/tex]
Where,
P is the number of arrangements.
r is the of objects selected.
n is the total numbers of object.
According to the question.
We have a word "COUNT".
Total number of letters in word "COUNT" is 5.
⇒ Total number of objects, n = 5
Since, we have to form different words by using 5 letters of count.
⇒ Total number of objects we have to select, r = 5
Therefore, the total number of ways to arrange the letters of "COUNT" is given by
[tex]5P_{5}=\frac{5!}{(5-5)!}[/tex]
⇒[tex]5P_{5} =\frac{5!}{0!}[/tex]
⇒[tex]5P_{5} =\frac{5!}{1}[/tex] (because,0! = 1)
⇒[tex]5P_{5} = 5(4)(3)(2) = 120 ways[/tex]
Hence, there are total 120 ways to arrange the letters of word "COUNT".

A statement that best compares the average values of the number of fish caught at both lakes daily:
There is a significant difference between the sample means.
What is average?The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the sum of the total number of observations by the total number of observations.
