Answer:
Change in percent = 30%
Step-by-step explanation:
Given:
First value = 30
Second value = 39
Find:
Change in percent
Computation:
Change in percent = [(Second value - First value) / First value]100
Change in percent = [(39 - 30) / 30]100
Change in percent = [(9) / 30]100
Change in percent = 30%

Answer:
The slope is 2
Step-by-step explanation:
To solve for slope, it's: y2-y1/ x2-x1.
The points can be (1,0) and (2,2) since they intersect with the slope.
You plug the points into the equation which is 2-0/ 2-1.
This will give you 2/1 or just 2.
Or you can just do rise over run. The slope is going up by 2 and across by 1.
GIVING 50 POINTS TO ANSWER. PLS ANSWER ASAP. I MARK BRAINLIEST.
Answer:
you can do it !! .. here's how
Step-by-step explanation:
slope = rise / run
pick any two coordinates that the line goes through
set up the equation using the y - coordinates at the top and the x- coordinates on the bottom
subtract the two y - coordinates and then the x-coordinates
then you will get your answer.

A total of 2 yards of fabric is used to make 5 identical pillows. How much fabric is used for each pillow? Do not include units (yards) in your answer. Modified from EngageNY ©Great Minds Disclaimer
Answer:
2/5 yards of fabric
Step-by-step explanation:
A total of 2 yards of fabric is used to make 5 identical pillows. How much fabric is used for each pillow?
5 identical pillows = 2 yards of fabric
1 pillow = x yards
Cross Multiply
x yards × 5 pillows = 2 yards × 1 pillow
x yards = 2 yards × 1 pillow/5 pillows
x yards = 2/5 yards of fabric
Therefore, 2/5 yards of fabric was used for 1 pillow
El triple del cuadrado de un numero es igual a 6 veces ese numero cual es el numero que satiface el problma
Answer:
El numero es 2
Step-by-step explanation:
Sea x el número.
A partir de la pregunta, la expresión se puede representar matemáticamente como:
[tex]3x ^ 2 = 6x[/tex]
Divide ambos lados de la expresión por x
[tex]\frac{3x ^ 2}{ x} = \frac{6x }{ x}[/tex]
[tex]\frac{3x ^ 2}{ x} = 6[/tex]
[tex]3x = 6[/tex]
Divide ambos lados de la expresión por 3
[tex]\frac{3x}{3} = \frac{6}{3}[/tex]
[tex]x = \frac{6}{3}[/tex]
[tex]x = 2[/tex]
Por tanto, el número es 2

The corresponding angles of the triangles are equal. Then the triangles ΔFGH and ΔMLN are similar triangles.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
In triangle ΔLMN, the measure of the third angle is calculated as,
∠N + ∠M + ∠L = 180°
∠N + 51° + 36° = 180°
∠N = 93°
In triangle ΔFGH, the measure of the third angle is calculated as,
∠H + ∠F + ∠G = 180°
∠H + 51° + 36° = 180°
∠H = 93°
In triangles ΔFGH and ΔMLN, the corresponding angles are equal. Then the triangles ΔFGH and ΔMLN are similar triangles.

A tree casts a shadow of 28 feet. At the same time, a biologist who is 7 feet tall casts a shadow of 2 feet.
How tall is the tree?
O 8 feet
78 feet
14 feet

Answer:
Step-by-step explanation:
7/2 = t/28
t = 98 ft
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The height of the tree is equal to 98 feet.
What is Tangent (Tanθ)?
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
Using the tangent function of the trigonometry, we can write the ratio of the height to the base will be equal because the angle of sun rays is the same for both.
Height of Tree /Shadow of Tree = Height of the biologist / Shadow of the biologist
Height of the tree/ 28 = 7/2
Height of the tree = (28×7)/2
Height of the tree = 98 feet
Hence, the height of the tree is equal to 98 feet.

the mean of two numbers is 7.
the range of these two numbers is 8.
what are these two numbers?
The unknown two numbers are 11 and 3 where the mean of two numbers is 7 and the range of these two numbers is 8.
What are mean?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
The range of a given set of data is defined as the difference between the largest value and the smallest value.
Given that the mean of two numbers is 7 and the range of these two numbers is 8.
Let the pair of number be 11 and 3
11 + 3 = 14
14 / 2 = 7
Mean = 7
Also, the difference between the numbers are;
11 - 3 = 8
Range = 8
Therefore, the unknown two numbers are 11 and 3 where the mean of two numbers is 7 and the range of these two numbers is 8.

Find the equation of a line that passes through the point (4,2) and has a gradient of 5.
Leave your answer in the form y = mx + c
Answer:
The equation of a line in the slope-intercept form is:
y = 5x - 18
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptIn our case, we are given
m = 5Point (4, 2)now substituting m = 5 and (4, 2) in the slope-intercept form of the line equation to determine the y-intercept
y = mx + b
2 = 5(4) + b
20 + b = 2
subtract 20 from both side
20 + b - 20 = 2 - 20
b = -18
now substituting b = -18 and m = 5 in the slope-intercept form of the line equation
y = mx + b
y = 5x + (-18)
y = 5x - 18
Therefore, the equation of a line in the slope-intercept form is:
y = 5x - 18
