Find the total surface area of this cuboid.
Step-by-step explanation:
I just learned this in class lol
Find the area of all the sides.
This cubiod has 6 sides.
6 x 5 = 30
6 x 5 = 30
4 x 5 = 20
4 x 5 = 20
6 x 4 = 24
6 x 4 = 24
30 + 30 + 20 + 20 + 24 + 24 = 148
Thefore, the surface area of this cuboid is 148.

Ap calculus
9514 1404 393
Answer:
(c) 1.649
Step-by-step explanation:
For a lot of these summation problems it is worthwhile to learn to use a calculator or spreadsheet to do the arithmetic. Here, the ends of the intervals are 1 unit apart, so we only need to evaluate the function for integer values of x.
Almost any of these numerical integration methods involve some sort of weighted sum. For trapezoidal integration, the weights of all of the middle function values are 1. The weights of the first and last function values are 1/2. The weighted sum is multiplied by the interval width, which is 1 for this problem.
The area by trapezoidal integration is about 1.649 square units.
__
In the attached, we have shown the calculation both by computing the area of each trapezoid (f1 does that), and by creating the weighted sum of function values.

What is the measure of arc DGF
Answer:
DGF=226
Step-by-step explanation:
Angle 113 is a inscribed angle since two it is on the exterior of the circle. We can find the central angle by multiply 2 by 113.
113×2=226
Since the central angle measure 226, that means the arc DGF measures 226 degrees.
DGF=113

Given that x and y vary inversely and that y is 8 when x is 2, what is the constant of variation, k?
Answer:
16
Step-by-step explanation:
the equation is x = k / y
therefore k = x* y
k = 2*8
k= 16

The frequency, or pitch, of a musical note varies inversely with the wavelength. The speed of sound, 340.2 meters per second, is the constant of variation.
An “A” note in octave 5, has a frequency of 880 Hertz. What is the wavelength of the sound made by the tuner in meters?
Answer:
The wave length = 0.387 meters
Step-by-step explanation:
Remark
An inverse relationship is one of the variables is in the denominator of a fraction and the other is given on the other side of the equal sign. It sounds more complicated than it is. Here's that long sentence broken down to 3 letters.
f = k/w
Formula
f = k/w
f is the frequency
k is the speed of sound
w is the wavelength
Givens
f = 880 Hz
k = 340.2 m/s
w = ?
Solution
f = k/w
880 = 340.2/ w Multiply both sides by w
880*w = w* 340.2 /w
880*w = 340.2 Divide by 880
w = 340.2/880
w = 0.387 m
what does b equal?
-15 b - 25 = -2
Answer:
b = - [tex]\frac{23}{15}[/tex]
Step-by-step explanation:
- 15b - 25 = - 2
- 15b - 25 + 25 = - 2 + 25
- 15b = 23
- 15b ÷ - 15 = 23 ÷ - 15
b = - [tex]\frac{23}{15}[/tex]
Answer
90° − 25° = 65°

9. Use the graph of each polynomial function to find the factored form of the related polynomial.
Assume the polynomial has no constant factor.
A.
What are the zeros of this function? (2 points)
what is the factorization of the polynomial
Answer:
A) the zeros are; x = -2 and x = 4
B) y = (x + 2)(x - 4)
Step-by-step explanation:
A) The zeros are the values of x where the graph curve crosses the x-axis.
Looking at the graph, the curve crosses the x-axis at x = -2 and x = 4
Thus, the zeros are; x = -2 and x = 4
B) Factorization of the polynomial means that we transform the zeros into the polynomial.
Thus, we have; y = (x + 2)(x - 4)
So when y is zero, x = - 2 or 4 as earlier derived.

Step-by-step explanation:
Charla works at a clothing store. Her pay is calculated using the formula p = 550 +0.15t, where p is her total pay, d is the number of days
she worked, and is the amount of her total sales.
What were her total sales if her pay was $785 and she worked 5 days?
The total sales if her pay was $785, and she worked 5 days will be $1,000.
The correct equation is p = 55d + 0.15t.
What is simplification?Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
Charla works at a clothing store.
Her pay is calculated using the formula
p = 55d + 0.15t
where p is her total pay, d is the number of days she worked, and t is the amount of her total sales.
Then the total sales if her pay was $785, and she worked 5 days will be
785 = 55 × 5 + 0.15 t
0.15t = 510
t = $1,000

What is 20% of 50 and what would 10% equal
Answer:
20/100 x 50 is 10
10% would be 10/100 is fraction form
I want to help you on the first thing you said,
so always consider a percent as a fraction but there denominator is ALWAYS 100 (a way to remember that is that the word "cent" means 100). The word "of" means multiplication so that means your multiplying it with 50 and just do the multiplication.
