In a right triangle, angle φ has a tangent value of 1.40. The side adjacent to angle φ has a length of 9.0 inches. What is the length of the side opposite angle φ?
a. 6.4 inches
b. 12.6 inches
c. 9.1 inches
d. 54.4 inches
Answer:
b) 12.6 inches
Step-by-step explanation:
tangent is the ratio of the side opposite over adjacent, so if we let x= length of the opposite side, 1.40=x/9, x=12.6 inches
b) 12.6 inches

Daud bought a plot of land with an area of 6 2/5 km. He divided the land equally into 8 small plots. What was the total area of 3 of the small plots of land?
Answer: [tex]\dfrac{12}{5}\ km^2[/tex]
Step-by-step explanation:
Given
The area of land is [tex]6\frac{2}{5}\ km^2[/tex]
Daud divide the land into 8 equal plots
So, the area of a single small plot is
[tex]\Rightarrow \dfrac{\dfrac{30+2}{5}}{8}\\\\\Rightarrow \dfrac{32}{5\times 8}\\\\\Rightarrow \dfrac{4}{5}\ km^2[/tex]
The area of three such plots
[tex]\Rightarrow 3\times \dfrac{4}{5}\\\\\Rightarrow \dfrac{12}{5}\ km^2[/tex]

Sample Answer:
Both prisms are equal in volume, with it being 30 in^3. Although the triangle prism has a length of twice as much, this is countered by the formula for a triangular prism which requires for it to be divided by 2, where this is not present within the formula for a rectangular prism.
Step-by-step explanation:
For this, just pretend that h=1 to make the math easier. So the rectangular prism has a cross section that is 6 by 5 inches, so that will be its L & W.
The triangular prism has a cross section that is a 12 inch base times a 5 inch interior height, this will give the triangle's length and height respectively In this case, h will be its width, making the Base of the triangle which is Length * Width. Think of it like flipping over this prism, making the side facing you and make it the bottom of the prism.
Now, with the formulas for volume of the prisms:
Rectangular: L * W * H
Triangle: (L*W * H) / 2
Then just plug in the numbers:
Rectangular Prism:
L * H * H
6 * 5 * 1
30 * 1
30
Triangle Prism:
(12 * 5 * 1) / 2
60 / 2
30
They are equal to each other.
The graph represents the piecewise function:
Answer:
x if -3is less than x is less than -1
5 is -1 is less than x is less than 1
Step-by-step explanation:
You find the slope of the line for the first piece when the x-values range from -3 to -1.
For the second piece, the line is y=5 because the line is horizontal.
Answer:
x+3; 5
Step-by-step explanation:
The first piece, shows the diagonal part in Quadrant II.
The line segment is colinear with the line y=x+3, because the slope is 1, and the y-intercept is 3. So the piece would be defined as x+3.
The second line segment is the flat one, which has a slope of 0 and its y-intercept is 5. So the piece would be defined as 0x+5 or 5
Please help me find the range!
The three lines represent the amount of water, over time, in three tanks that are the same size. Which tank is filling most quickly? Choose 1 answer
Tank A
Tank B
Tank C
Answer:
Tank A
Step-by-step explanation:
If the lines goes accross each tank the first tank would fill up first then the next one and it keeps going.
Hope this helps!
Answer:
Tank A
Step-by-step explanation:
The tank that fills fastest will have the steepest line graphed. The steepest line is the graph for Tank A. Tank A fills the most in the least amount of time, so this is the answer.
I hope this helps :) Good luck ^^

Examine the expression. 17x - 34 Which is an equivalent expression? O 17*(1 + ) O 17x (1-2) O 17+(1-1) O 17*(1 + 2)
Answer:
17(x-2)
Step-by-step explanation:
Given the expression
17x - 34
We are to factorize it
Get their factors
17x = 17 * x
34 = 17 * 2
Since 17 is common to both factors, hence 17 is the GCF
17x - 34 = 17(x - 2)
Hence the equivalent expression is 17(x-2)

Set up to different integrals that match the endpoints
so in our case it would look like
[tex]\int\limits^0_{-2} {x} \, dx +\int\limits^1_0 {x+1} \, dx[/tex]
now it's just a matter of computing it
[tex]\int\limits^0_{-2} {x} \, dx =x^2\\0^2-(-2)^2=4\\\int\limits^1_0 {x+1} \, dx =\frac{x^2}{2}+x\\\frac{1}{2}+1-0=\frac{3}{2}\\\frac{3}{2}+4=\frac{11}{2}[/tex]

66 oz = __lb in a mixed number
Answer:
[tex]4\frac{1}{8}[/tex] pounds
Step-by-step explanation:
1 pound = 16 ounces
[tex]\frac{66}{16} =\frac{y}{1}[/tex]
16 × y = 66 × 1
16y = 66
16y ÷ 16 = 66 ÷ 16
[tex]y=4\frac{1}{8}[/tex]
Answer: 4 1/8
Step-by-step explanation:
16 oz in 1 lb
64 -> 4 lb
2/16 = 1/8
4 1/8 lb

Marcus is choosing 4 books to read from a list of 15 books. If order matters, how many ways can he choose to read the books?
4
32,760
23,760
60
Answer:
32,760
Step-by-step explanation:
Given :
Since the order matters, we use the permutation relation :
Recall :
nPr = n! ÷ (n - r)!
n = 15 ; r = 4
15P4 = 15! ÷ (15 - 4)!
15P4 = 15! ÷ 11!
15P4 = (15 * 14 * 13 * 12)
15P4 = 32,760

Answer:
the first angle is 180 - (90 + 60) = 30
second angle is 180 - (45 + 90) = 45
30 + 45 = 75

Which is greater, the circumference of a circle with radius 3 ft, or the distance around a semicircle with diameter 16 A? By how much? circle, by 40 ft circle, by 2n ft semicircle, by 40 ft Od semicircle, by 21 ft
Answer:
Option C
Step-by-step explanation:
Circumference of a circle = [tex]2\pi r[/tex]
Circumference of a circle with radius 3 ft= [tex]2\pi *3 = 6\pi[/tex]
Circumference of a circle with radius 8 ft or 16 ft= [tex]2\pi *8/2 = 16\pi/2 = 8\pi[/tex]
The difference between the two circle
[tex]8 \pi - 6\pi = 2\pi \\= 2 * 3.14\\= 6.28\\[/tex]
Hence, option C is correct

Answer:
∠1 = 48
∠2 = 132
∠4 - 132
Step-by-step explanation:
∠3 and ∠1 are vertical angles
vertical angles are congruent ( equal to each other )
So if ∠3 = 48° then ∠1 also = 48°
∠3 and ∠4 are supplementary angles
supplementary angles add up to equal 180°
Hence, ∠3 + ∠4 = 180
48 + ∠4 = 180
180 - 48 = 132
Hence, ∠4 = 132
∠4 and ∠2 are vertical angles
Like stated previously vertical angles are congruent
Hence, ∠2 = 132
