Answer: [tex]2(3x+5)=3x-2[/tex] , required equation.
Step-by-step explanation:
As per given we have,
First number = [tex]\dfrac13[/tex] of second number. (i)
Second number = Third number - 5 (ii)
2 (third number)= Second number - 5 (iii)
Put x= first number in (i).
so, [tex]x=\dfrac13[/tex] of second number.
⇒ second number =[tex]3\times x=3x[/tex]
From (ii)
[tex]3x=[/tex] Third number - 5
⇒ Third number =[tex]3x+5[/tex]
From (iii)
[tex]2(3x+5)=3x-2[/tex] , required equation.

The ratios are 44:20=11:5
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
The given ratios are 44:20 = ?:5
we have to find the number in question mark place.
Let question mark be taken as x.
The ratios can be written in the form of fraction
44/20=x/5
Apply cross multiplication
44×5=20x
220=20x
Divide both sides by 20
x=220/20
x=11

Angle θ forms a reference angle that is below the positive x axis (in quadrant IV). What will be the signs on the sine and cosine of angle θ?
Answer:
sin(θ) is negative, cos(θ) is positive
Step-by-step explanation:
Cosine corresponds to the x-coordinate within the unit circle, sine corresponds to the y-coordinate. In quadrant I, they are both positive, in quadrant II, x is negative whilst y is positive, and you would just continue by how they correspond as show in the unit circle, therefore, in quadrant IV, x is positive, y is negative.
How can i use scatter plots to analyze two sets of data?

Find the slope of -5x+4Y=-16
Given parameters:
Find the slope of the line;
-5x + 4y = -16
To find the slope of this line, we must express it in linear form according to the equation below;
y = mx + c
Where x and y are the coordinates
m is the slope
c is the intercept
Now let us write the given equation in this form;
-5x + 4y = -16
Take add +5x to both sides;
-5x + 4y + 5x = 5x - 16
4y = 5x - 16
Now, divide through by 4;
[tex]\frac{4y}{4}[/tex] = [tex]\frac{5x}{4}[/tex] - [tex]\frac{16}{4}[/tex]
y = [tex]\frac{5x}{4} - 4[/tex]
So the slope of the line is [tex]\frac{5}{4}[/tex]
An angle measures 70° more than the measure of its complementary angle. What is the measure of each angle?
Step-by-step explanation:
Let an angle = x
x= 70+(90-x)
x= 160-x
2x=160
x=80
So angle is 80 and it's complementary angle would be 10
Answer:
55∘ and 125∘
Step-by-step explanation:
Supplementary angles sum to
180∘
let one angle be [tex]x[/tex]
then the other angle is [tex]x+70[/tex]
summing the 2 angles gives
[tex]x+x+7=180[/tex]
[tex]2x+70=180[/tex]
subtract 70 from both sides
[tex]2x=180 -70=110[/tex]
divide both sides by
[tex]2x=\frac{110}{2} =55[/tex]
thus the angles are
55∘ and 55 + 70= 125∘
what are the x- and y- intercepts for the graph of 3x + y = 15?
Answer:
X intercept=(5,0) and Y intercept=(0,15)
Step-by-step explanation:
3x + y = 15
to find the x int, sub in 0 for y and solve for x
3x + 0 = 15
3x = 15
x = 15/3
x = 5....so the x int is (5,0)
to find the y int, sub in 0 for x and solve for y
3(0) + y = 15
y = 15....so the y int is (0,15)

Answer:
7. odd angles, 143°; even angles, 37°
8. odd angles, 159°; even angles, 21°
9. even angles, 34°; odd angles, 146°
10. even angles, 29°, odd angles, 151°
Step-by-step explanation:
Angles 1 and 3 are vertical angles, so are congruent. The same can be said of angles 2 and 4. Each odd-numbered angle is supplementary to each even-numbered angle.
__
7. m∠1 = m∠3 = 143°, m∠2 = m∠4 = 180° -143° = 37°
8. m∠1 = m∠3 = 159°, m∠2 = m∠4 = 180° -159° = 21°
9. m∠2 = m∠4 = 34°, m∠1 = m∠3 = 180° -34° = 146°
10. m∠2 = m∠4 = 29°, m∠1 = m∠3 = 180° -29° = 151°

A cylinder has radius 9 inches and height 15 inches. A cone has the same radius and height
Find the volume of the cylinder
Find the volume of the cone
What fraction of the cylinder's volume is the cone's volume?
Answer:
See below
Step by step explanation:
Step-by-step explanation:
For cylinder:
r = 9 inches
h = 15 inches
[tex]V_{cylinder}=\pi r^2 h[/tex]
[tex]\implies V_{cylinder}=3.14 (9)^2 (15)[/tex]
[tex]\implies\huge\purple{ V_{cylinder}=3,815.1\:inch^3}[/tex]
[tex]V_{cone}=\frac{1}{3} V_{cylinder}[/tex]
[tex]\implies V_{cone}=\frac{1}{3}\times 3,815.1[/tex]
[tex]\implies \huge\orange{V_{cone}=1,271.7\: inch^3}[/tex]
Cone's volume is one third of the cylinder's volume.
What is the area of the region in the first quadrant bounded on the left by the graph of x=y^2/2 and on the right by the graph of x=3y−4 for 2≤y≤4 ?
The area of the region is -2/3 square units
The area bounded by the regionSince the region is bounded on the left by x = y²/2 and on the right by x = 3y - 4 for 2 ≤ y ≤ 4, the area of the region is given by
[tex]A = \int\limits^4_2 {\frac{y^{2}}{2} } \, dy - \int\limits^4_2 {(3y - 4)} \, dy \\[/tex]
Integrating, we have
A = [y³/6]₂⁴ - [3y²/2 - 4y]₂⁴
A = [4³/6 - 2³/6] - [3(4)²/2 - 4(4) - {3(2)²/2 - 4(2)]}]
A = [64/6 - 8/6] - [3(16)/2 - 16 - {3(4)/2 - 8]}]
A = [64/6 - 8/6] - [3(16)/2 - 16 - {3(4)/2 - 8]}]
A = [64/6 - 8/6] - [3(8) - 16 - {3(2) - 8]}]
A = [(64 - 8)/6] - [3(8) - 16 - {3(2) - 8]}]
A = [56/6] - [24 - 16 - {6 - 8}]
A = [56/6] - [8 - {-2}]
A = [56/6] - [8 + 2]
A = [56/6] - [10]
A = 56/6 - 10
Taking the L.C.M, we have
A = (56 - 10 × 6)/6
A = (56 - 60)/6
A = -4/6
A = -2/3 square units
So, the area of the region is -2/3 square units

The area of a baseball field bounded by home plate, first base, second base, and third base is a square. If a player at first base throws the ball to a player at third base, what is the distance the player has to throw? 90 feet is first base 90 feet at third base
Answer:
ta side from one base to next has length of x. so we know each side has length x and the shape they make is a square. This means we are only searching for the diagonal of a square. remember that a diagonal forms and isoscoles right triangle with the 2 sides being equal and the diagonal as the hypotenuse. Using pythagoream theorem we can say
a^2 + b^2 = c^2 all side lengths are x so we can put x in for a and b to get
x^2 + x^2 = c^2
2x^2 = c^2
c = x * squareroot(2)
so if the length between bases is 90 ft
c = 90 ft * squareroot(2)
c = 127.28 ft
