Answer:
12.2h + 18.2 yd^2.
Step-by-step explanation:
Surface area = 2hl + 2hw + 2lw where h = height, w = width and l = length.
= 2 * 2.6h + 2 * 3.5h + 2*2.6*3.5
= 5.2h + 7h + 18.2

which expression correctly shows the sum of the product of 9 and 5 difference of 24 and 6?
Answer:
72
Step-by-step explanation:
When you multiply 9 and 5 you get 45. When you subtract 6 from 24 you get 18.
45 + 18 = 72
If helpful please mark me brainliest!
The correct expression for the sum of the product of 9 and 5 and the difference of 24 and 6 will be (9 × 5) + (24 -6) which will be equal to 63.
What is an expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations.
A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the given statement in the question,
Product of 9 and 5 i.e., 9 × 5 and,
Difference of 24 and 6 i.e., 24 - 6
Thus sum will be,
(9 × 5) + (24 - 6)

Find the length of the unknown side.
25 cm
15 cm
Answer:
b = 20 cm.
Step-by-step explanation:
Define and explain:
This is a right triangle, so the Pythagorean Theorem applies.
The Pythagorean Theorem states that the sum of the squared legs will equal the squared length of the hypotenuse.
The legs of a triangle are the sides that form the right angle.
The hypotenuse is the longest side; the hypotenuse is always diagonal from the small square indicating a right angle.
Solve:
[tex]a^2+b^2=c^2[/tex]
[tex]a,b-legs[/tex]
[tex]c-hypotenuse[/tex]
[tex]15^2+b^2=25^2[/tex]
[tex]225+b^2=625[/tex]
[tex]625-225=400[/tex]
[tex]b^2=400[/tex]
[tex]b=20[/tex]

what is the average rate of change of f(x) = (x + 3)2 − 2
Answer:
When we have a function f(x), the average rate of change in the interval (a, b) is:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
In this case, we have the function:
f(x) = (x + 3)^2 - 2
(but we do not have the interval, and I couldn't find the complete question online)
So if for example, we have the interval (2, 4)
The average rate of change will be:
[tex]r = \frac{(4 + 3)^2 - 2 - (2 + 3)^2 + 2}{4 - 2} = \frac{24}{2} = 12[/tex]
If instead, we want the rate of change in a differential dx around the value x, we need to differentiate the function (this is way more complex, so I will define some rules first).
Such that the rate of change, in this case, will be:
f'(x) = df/dx
For a function like:
g(x) = x^n + c
g'(x) = n*x^(n - 1)
And for:
h(x) = k( g(x))
h'(x) = k'(g(x))*g'(x)
So here we can write our function as:
f(x) = k(g(x)) = (x + 3)^2 - 2
where:
g(x) = x + 3
k(x) = x^2 - 2
Then:
f'(x) = 2*(x + 3)*1 = 2*x + 6
That is the rate of change as a function of x (but is not an "average" rate of change)
Use the graph of f to find f(2).

) Final averages are typically normally distributed with a mean of 72 and a standard deviation of 12.5. Your professor states that the top 8% of the class will receive an A; the next 20% will receive a B; the next 42% will receive a C; the next 18% will receive a D; and the bottom 12% will receive an F. What grade must you exceed in order to receive a grade of C or better
Answer:
65.45
Step-by-step explanation:
Zscore = (x - mean) / standard deviation
x = score
Percentage below C :
D = 18% ; F = 12%
Sum = 30%
Obtain the Zscore for the proportion below D
P(Z < 0.30) = -0.524
Hence, Zscore = -0.524
Put Zscore = -0.524 in the equation :
-0.524 = (x - 72) / 12.5
-0.524 * 12.5 = x - 72
-6.55 = x - 72
-6.55 + 72 = x
x = 65.45
To receive a grade of C or better, score must be atleast 65.45

The mode doesnt need to be 9 if there is more than 1 mode, so that isnt it. Eliminating D. The mean can most definatly be determinded if we know the values. This elimnates C. The mean can be 6.875, but we dont know, so we can assume it IS 6.875. This eliminates F.

angles k and p are supplementary and the measure of k is twice that of p, find both angles in degrees
Answer:
p=60 and k=120
Step-by-step explanation:
So, with supplementary angles, there is a max of 180 degrees (because it is half of a circle.) With this information, we can make an equation. Let's make it.
If the measure of k is twice of p, then k=2p
Equation= 2p+p=180
Now let's isolate p and find out what it is!
2p+p=3p so...
3p=180
Now let's divide 3 on both sides.
That would equal...
p=60
That means p=60 for sure. However, since k is twice of p, we need to double p to find out what k is.
60 x 2=120
Final answer= p=60 k=120
Hope this helped!! If you have any questions, make sure to write them in the comments!
Answer:
k = 120
p = 60
Step-by-step explanation:
k = p2
p+p2 = 180
p3 = 180
p3/3 180/3
p = 60
k = 60 × 2
k = 120

Answer:
a. Area = 1,017.36 cm²; Circumference = 113.04 cm
b. Area
c. Circumference
Step-by-step explanation:
Given:
Radius (r) = 18 cm
π = 3.14
a. Area of the mirror = area of circle = πr²
Plug in the values
Area = 3.14*18²
Area = 1,017.36 cm²
Circumference = 2πr
Circumference = 2*3.14*18
Circumference = 113.04 cm
b. The area of the glass would be used in finding the amount of glass needed caused it's the surface of the glass that is to be replaced.
c. The silver wire would be placed around the mirror, therefore, it is the circumference that would be needed in finding the amount of wire needed since the circumference is the perimeter round the mirror.
