The fractions equivalent to 2/5 are 4/10, 6/15, 8/20, etc.
Now, According to the question:-
Equivalent fractions can be written by multiplying or dividing both the numerator and the denominator by the same number. This is the reason why these fractions get reduced to the same number when they are simplified.
Let us understand the two ways in which we can make equivalent fractions:
Multiply the numerator and the denominator by the same number, or,Divide the numerator and the denominator by the same number.Hence, the equivalent fractions for 2/5 are:
(2/5) × (2/2) = (2 × 2) / (5 × 2) = 4/10
(2/5) × (3/3) = (2 × 3) / (5× 3) = 6/15
(2/5) × (4/4) = (2 × 4) / (5 × 4) = 8/20
Thus, 4/10, 6/15, 8/20 are equal to 2/5,

A ball is thrown into the air. Its height in
feet after t seconds is given by the
function h(t) = −5t² + 20t. How high will
the ball be after 3 seconds?
Answer:
15 ft
Step-by-step explanation:
h(t) = −5t² + 20t (Given)We need to find: height of the ball after 3 seconds.So, plug t = 3 in the above equation, we find:h(3) = −5(3)² + 20(3)->h(3) = −5(3)² + 20(3)->h(3) = −5(9) + 60->h(3) = −45 + 60->h(3) = 15 feetWhat are the four ways to prove that two triangles are similar?
Using the SAS(Side-Angle-Side) Theorem, ASA(Angle-Side-Angle) Theorem, SSS(Side-Side-Side) Theorem and AA(Angle-Angle) Theorem we can easily prove that two triangles are similar.
If two triangles have an equal number of comparable angles and sides, they are said to be similar.
Similar figures are items that have two or more figures with the same shape but varying sizes.
Using the SAS(Side-Angle-Side) Theorem, ASA(Angle-Side-Angle) Theorem, SSS(Side-Side-Side) Theorem and AA(Angle-Angle) Theorem we can easily prove that two triangles are similar.
A portion on one polygon must correspond perfectly to a part in another polygon that is in a similar place. Even though two triangles are oriented differently from one another, you can conclude that their angles match if you can spin them to align in the same direction and notice that their angles are similar.

Solve for k.
k² - 19k - 20 =0
Answer:
k = -1, 20
Step-by-step explanation:
k² - 19k - 20 = 0
k² + 1k - 20k - 20 = 0 ==> 1 * (-20) = -20 and -20 + 1 = -19
k² + k - 20k - 20 = 0
k(k+1) - 20(k+1) = 0 ==> factor and simplify
(k-20)(k+1) = 0
k-20=0 ==> k=20
k+1=0 ==> k=-1
k = -1, 20
Answer:

Given AABE~ ADCE and BC intersects AD at E, what is the value of y
Answer:
Step-by-step explanation:
The value of y is unclear given the information provided. However, if BC intersects AD at E, then it stands to reason that y would be equal to the value of x. This is because, if BC intersects AD at E, then the two lines are parallel and therefore have the same value for y.
isabella is making a huge flag of her country, the republic of seychelles, on a canvas 202020 by 101010 meters long. to do that, she has to draw a diagonal line that begins at the bottom-left corner and ends at the top side of the flag, 6.66.66, point, 6 meters to the right. since the ends of the diagonal line are too far to put a ruler between them, isabella wanted to find the angle of the diagonal and draw it using a protractor. what is the angle, in degrees, between the diagonal line and the left edge of the flag? round your final answer to the nearest tenth.
The angle, in degrees, between the diagonal line and the left edge of the flag is 67.8 degrees.
To find the angle between the diagonal line and the left edge of the flag, you can use the Pythagorean theorem to calculate the length of the hypotenuse (the diagonal line) and one of the legs (the horizontal distance from the bottom-left corner to the end of the diagonal line). The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

What is the arithmetic mean of the following numbers 3 5 6 7 9 6 8?
The mean for a given set of observations is 6.286.
What is mean?The mean is the average of a set of variables in mathematics and statistics. The mean may be calculated in a variety of methods, including the simple arithmetic mean (add the numbers and divide the total by the number of observations), geometric mean, and harmonic mean. A data set's mean (average) is calculated by summing all of the numbers in the set and then dividing by the number of values in the set. When a data collection is arranged from least to largest, the median is the midway value. The mode is the number that appears the most frequently in a data collection.
Here,
given set of observation,

a) (-5, -6) b) (4, 11) c) (0, 2)
d) (10, 22)
Which pair could be used
Another point on the line is (0,2).
The equation of a line, in point-slope form, is given by:
[tex]$$y-y_0=m\left(x-x_0\right)$$[/tex]
In which [tex]$\mathrm{m}$[/tex]is the slope and the point is [tex]$\left(x_0, y_0\right)$[/tex]
Slope of [tex]$9 / 5$[/tex] if one of the points on the line is [tex]$(-10,-16)$[/tex]
This means that [tex]$m=\frac{9}{5},\left(x_0, y_0\right)=(-10,-16)$[/tex]. So
[tex]$$\begin{aligned}& y-y_0=m\left(x-x_0\right) \\& y-(-16)=\frac{9}{5}(x-(-10)) \\& y+16=\frac{9}{5}(x+10)\end{aligned}$$[/tex]
Which of the following could be another point on the line?
We have to find a point for values of [tex]$x$[/tex] and [tex]$y$[/tex] which gives us an identity. So
x=-5, y=-6
Lets see
[tex]$$\begin{aligned}& -6+16=\frac{9}{5}(-5+10) \\& 10=\frac{9 * 5}{5} \\& 10=9 > \text { False }\end{aligned}$$[/tex]

False

What is the solution of the system of equations y =- 4x 10?
The solution of the given system of equation is (8, -22).
In the given question we have to find the solution to the system of equations:
y = -4x + 10 and y = -2x - 6
We can solve the system of equation using the substitution method.
In substitution method we have to put the the value of one variable from one equation to the other equation.
We have to equations:
y = -4x + 10...................................(1)
y = -2x - 6.............................(2)
Now putting the value of y from the equation 1 in equation 2
-4x + 10 = -2x - 6
Add 6 on both side we get
-4x + 16 = -2x
Add 4x on both side, we get
2x = 16
Divide by 2 on both side, we get
x = 8
Now the value of x is 8.
Now putting the value of x in equation 1
y = -4(8) + 10
y = -32 + 10
y = -22
Hence, the solution of the given system of equation is (8, -22).

II. The vertex of f(x) is in quadrant 4
III. f(x) has no x-intercepts

A. I and IV
B. II and IV
C. I and III
D. II and III
For the given statement f(x)= a(x-h)² + k is the vertex form of a parabola.
If a < 0, h> 0 and k < 0 Option B is correct.
Vertex of a Parabola
The vertex of a parabola is the point where the parabola crosses its axis of symmetry. If the coefficient of the x2 term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape. If the coefficient of the x2 term is negative, the vertex will be the highest point on the graph, the point at the top of the “ U ”-shape.Given that:
f(x)= a(x-h)² + k
If a < 0, h> 0 and k < 0 then
f(x) = -1 (x - 1)^2 - 1
= -1([tex]x^{2} + 1^{2} - 2x[/tex]) - 1
= [tex]-x^{2} -1 + 2x[/tex] - 1
f(x) = -([tex]x^{2} - 2x + 2[/tex])

The intersection of Beech Street and fourth Street is 150 yards east of the intersection of Fort Street and Clover Street how many yards south is it
The amount of yards south that the intersection of Fort Street and Clover Street is given as follows:
450 yards.
How to obtain the slope?The slope of an inclined object is obtained as the division of the vertical distance of the street by the horizontal distance of the object.
The distances are classified as follows:
Vertical: south is negative, north is positive.Horizontal: west is negative, east is positive.The slope of the street is given as follows:
-3.
The east distance is given as follows:
150 yards.
Thus the south distance can be identified applying the slope as follows:
-3 = S/150
S = -3 x 150
S = -450 yards.
The negative number represents that the direction is south, hence the distance is only of 450 yards.
