Answer:
ZR = 15
Step-by-step explanation:
Centroid of a triangle is a point inside the triangle where all medians meet.
And centroid divides the medians in the ratio of 2:1
By this property,
ZM : ZR = 2 : 1
ZM = 30 [Given]
Let the measure of median MR = a units
Therefore, ZM = [tex](\frac{2}{2+1})(MR)[/tex]
30 = [tex]\frac{2}{3}(a)[/tex]
a = 45 units
Now, ZR = [tex](\frac{1}{2+1})(MR)[/tex]
ZR = [tex](\frac{1}{3})(45)[/tex]
ZR = 15

The number of tree shades and evergreens will be 42 and 36, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
An engineer purchased 78 trees at an all-out cost of $4050. The overhanging trees cost $45 each and the evergreens cost $60 each.
Let 'x' be the number of tree shades and 'y' be the number of evergreens. Then the equations are given as,
x + y = 78 ...1
45x + 60y = 4050 ...2
From equations 1 and 2, then we have
45(78 - y) + 60y = 4050
15y = 540
y = 36
Then the number of tree shades will be given as,
x + 36 = 78
x = 78 - 36
x = 42
The number of tree shades and evergreens will be 42 and 36, respectively.

To find:
The domain of the given function in interval notation.
Solution:
We have,
[tex]f(x)=(x+3)^2[/tex]
Domain is the set of x-values or input values.
The given function is a quadratic function and domain of the quadratic function is all real number. The function is defined for all values of x. So, domain of the given function is the set of all real numbers.
Domain = Set of all real numbers
Domain = (-∞,∞)
Therefore, the domain of the given function is (-∞,∞).

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. The volume of each small box is 8 cubic feet and the volume of each large box is 23 cubic feet. What would be the total volume, in cubic feet, of 11 small boxes and 13 large boxes? What would be the total volume, in cubic feet, of
s
s small boxes and
l
l large boxes
Answers
Therefore 11 X 8 = 88 cubic feet form the small boxes.
23 X 13 = 299 cubic feet for the large boxes
TOTAL = SMALL + LARGE
TOTAL = 88 + 299 = 387 cubic feet
Part 2: total = small + large
Each small is 8 cubic feet and the number of small boxes is “s” so each means multiply so 8s gives us the total volume from small boxes. Large boxes are 23 each so:
Total = 8s + 23l

En un triángulo rectángulo A es un ángulo agudo y Sen A = 4/5 ¿Cuál será el valor de Tan A?
Answers
Answer:
[tex]\displaystyle \tan A=\frac{4}{3}[/tex]
Step-by-step explanation:
Funciones Trigonométricas
La identidad principal en trigonometría es:
[tex]sen^2A+cos^2A=1[/tex]
Si sabemos que A es un ángulo agudo (que mide menos de 90°), su seno y coseno son positivos.
Dado que Sen A = 4/5, calculamos el coseno:
[tex]cos^2A=1-sen^2A[/tex]
Sustituyendo:
[tex]\displaystyle cos^2A=1-\left(\frac{4}{5}\right)^2[/tex]
[tex]\displaystyle cos^2A=1-\frac{16}{25}[/tex]
[tex]\displaystyle cos^2A=\frac{25-16}{25}[/tex]
[tex]\displaystyle cos^2A=\frac{9}{25}[/tex]
Tomando raíz cuadrada:
[tex]\displaystyle cos\ A=\sqrt{\frac{9}{25}}=\frac{3}{5}[/tex]
La tangente se define como:
[tex]\displaystyle \tan A=\frac{sen\ A}{cos\ A}[/tex]
Substituyendo:
[tex]\displaystyle \tan A=\frac{\frac{4}{5}}{\frac{3}{5}}[/tex]
[tex]\displaystyle \tan A=\frac{4}{3}[/tex]

Step-by-step explanation:
For no 1
25 - 3x = 40
- 3x = 40 - 25
- 3x = 15
- x = 15 / 3
Therefore x = - 5
Now for no. 2
1/3 ( x - 10) = - 4
( x - 10 ) = - 12
x = - 12 + 10
Therefore x = - 2
