Answer:
0.11659...cm3
Step-by-step explanation:
To find volume you would have to plug it in the formula Volume= Mass / density so if we plug it in it will be, X(volume): 26(mass)/223(density) you will get 0.11659...cm3

PR / Sin(Q) = QR / Sin(P)
53 / Sin(90) = 45 / Sin(P)
53 / 1 = 45 / Sin(P)
Sin(P) = 45 / 53
Sin(P) = 0.8490566038
P = 58.11 degrees
Answer:
58.11°
Step-by-step explanation:
tan P = 45/28 = 1.607
< P = tan`¹ 1.607 = 58.11°

Answer:
∠ A ≈ 44.42°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos A = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{5}{7}[/tex] , then
∠ A = [tex]cos^{-1}[/tex] ([tex]\frac{5}{7}[/tex] ) ≈ 44.42° ( to the nearest hundredth )

What conclusion can be determined from the dot plot below? A. The median of the data set is 3. B. The mean of the data set is 3. C. The range of the data set is 5. D. The number of observations is 15.
Given:
Consider the below figure attached with this question.
To find:
The conclusion that can be determined from the dot plot.
Solution:
The number of dots in the dot plot is 15. So, the number of observations is 15 and option D is correct.
The data set represented by the dot plot is:
2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 6, 6
Number of observations is 15, which is an odd number. So, the median of the data set is:
[tex]Median=\dfrac{15+1}{2}\text{th term}[/tex]
[tex]Median=\dfrac{16}{2}\text{th term}[/tex]
[tex]Median=8\text{th term}[/tex]
[tex]Median=4[/tex]
The median of the data set is 4. So, option A is incorrect.
Mean of the data set is:
[tex]Mean=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}[/tex]
[tex]Mean=\dfrac{2+2+3+3+3+4+4+4+4+4+5+5+5+6+6}{15}[/tex]
[tex]Mean=\dfrac{60}{15}[/tex]
[tex]Mean=4[/tex]
The mean of the data set is 4. So, option B is incorrect.
The range of the data set is:
[tex]Range = Maximum - Minimum[/tex]
[tex]Range = 6-2[/tex]
[tex]Range = 4[/tex]
The range of the data set is 4. So, option C is incorrect.
Therefore, the correct option is D.

If 5x + 2 = 17, then 12x =____?
36
Step-by-step explanation:
5x is 15
x is 3
12 times 3 is 36
Answer:
5x + 2 = 17
5x = 17 - 2
5x = 15
x = 3
Therfore, 12x = 12 (3) = 36

✨find the surface area of the right cone shown. (Around the result to two decimal place)✨
Answer:
A = 388.58 cm^2
Step-by-step explanation:
For a cone whose base has a radius R, and a hypotenuse S, the area is:
A = pi*R^2 + pi*R*S
Where pi = 3.14
In this case, we can see that the diameter is: 15cm
Then the radius, half of the diameter, is:
R = 15cm/2 = 7.5cm
The hypotenuse is 9cm, then S = 9cm
A = 3.14*(7.5cm)^2 + 3.14*(9cm)*(7.5cm) = 388.575 cm^2
Rounding to two decimal places, we need to look at the third one, which is a five, so we need to round up:
A = 388.58 cm^2

Answer:
x = - 1
Step-by-step explanation:
Given
4x = x^2 - 5 Transfer 4x to the right side.
Solution
x^2 - 4x - 5 = 0 Factor
(x - 5)(x + 1)
You want the negative solution. That means that the middle sign must be plus.
x + 1 = 0 Subtract 10 from both sides
x = - 1 Ten on the left disappears by the subtraction process.
Is that correct?
4x = x^2 - 5
x = - 10
4*(-1) = (-1)^2 - 5
-4 = ? 1 - 5
-4 = - 4
and it does work.

convert 374F in base 16 to octal
33517
Step-by-step explanation:Method 1
Given:
374F in base 16
To convert to octal;
(i) convert each digit in the number to binary
3 = 0011
7 = 0111
4 = 0100
F = 1111
(ii) join the bits together starting from the first i.e
374F = 0011 0111 0100 1111
(iii) starting from the right to left, group the bits together, each group having 3 bits
374F = 0 011 011 101 001 111
(iv) the group with number of bits less than 3 should be padded with zero.
374F = 000 011 011 101 001 111
(v) convert each of the groups in (iv) above to decimal as follows:
000 = 0
011 = 3
011 = 3
101 = 5
001 = 1
111 = 7
(vi) combine the result above to get;
033517
The first zero can be removed
33517
Therefore, the number in octal is 33517₈
Method 2
Given:
374F in base 16
To convert to octal;
i) convert the number to decimal as follows;
a. Multiply each digit by 16 raised to the power of one less than their position starting from the leftmost digit.
=> 3 is at position 4, so we have
3 x 16⁴ ⁻ ¹ = 3 x 16³
=> 7 is at position 3, so we have
7 x 16³ ⁻ ¹ = 7 x 16²
=> 4 is at position 2, so we have
4 x 16² ⁻ ¹ = 4 x 16¹
=> F is at position 1, so we have
F x 16¹ ⁻ ¹ = F x 16⁰
b. Add each of the terms found in (a) together.
(3 x 16³) + (7 x 16²) + (4 x 16¹) + (F x 16⁰)
c. Remember that F = 15 in decimal. Therefore, substitute F = 15 into the result in (b)
(3 x 16³) + (7 x 16²) + (4 x 16¹) + (15 x 16⁰)
d. Solve the result in (c)
(3 x 4096) + (7 x 256) + (4 x 16) + (15 x 1)
12288 + 1792 +64 + 15
14159
Therefore,
374F in decimal is 14159
(b) Now convert the decimal to octal by dividing by 8 and noting the remainder.
8 | 14159
8 | 1769 r 7
8 | 221 r 1
8 | 27 r 5
8 | 3 r 3
| 0 r 3
Taking the remainders from bottom up gives
33517₈
Therefore, the number in octal is 33517₈

True or false? f (x) = 2 · (1/5)^x represents an exponential function growth.
Hi there!
[tex]\large\boxed{\text{False.}}[/tex]
f(x) = 2(1/5)ˣ
Recall the form of an exponential function:
f(x) = a(b)ˣ where:
a = initial value
b = rate of decay/growth
If b > 1, the function is undergoing exponential growth. If b < 1, then the function is undergoing exponential decay.
1/5 < 1, so the function is undergoing exponential decay, not growth.

This is the same as saying 27 cubic inches
===========================================================
Explanation:
We get the volume of a cube by using the formula
V = s^3
where the cubed exponent is directly tied together with the idea of volume being in cubic units. In this case, s = 3 which leads to
V = s^3
V = 3^3
V = 3*3*3
V = 27 cubic inches
As another example, let's say s = 4. That means
V = s^3
V = 4^3
V = 4*4*4
V = 64
We multiply the side length by itself having three copies total. This formula only applies to cubes. A more generalized formula for rectangular blocks is V = L*W*H where L,W,H are the length width and height in that order. This generalized formula allows for side lengths to be different, but if L = W = H, then it makes more sense to go with the first formula instead.

Answer:
x=24 2x=48
Step-by-step explanation:
We first do 112-64 which will give us 2x.
So, we know 48=2x.
divide both sides by two and we get:
x=24
Answer:
B
Step-by-step explanation:
2x and 48 are opposite from each other, making them equal
if you put them into an equation to solve for x, you get:
2x=48
/2 /2
x=24
now that you have x, you can plug it back into the original equation to get: 48
