Step-by-step explanation:

Answer: I believe A is 52 degrees.

Solution:  Find angle c (D + C adds up to 180 degrees cuz its a line)

So do 180-116=64 degrees

Assuming this is an isosceles triangle because the sides on d and c look equal, we know that those 2 angles add up to 128 degrees(64 + 64).

Therefore, since the shape is a triangle(adds up to 180 degrees) you just do 180 minus 128 to get angle A which is 52 degrees.

Answer: 33. r=13.6   34. m=12

Step-by-step explanation:

33.

-0.8+r=12.8

-0.8+r+0.8=12.8+0.8

r=13.6

If a gardener can care for the greens property in 5 hours and if his helper assists him, they will be done in 4 hours, then the number of hours it takes for the helper to do it alone is equal to 20.

The number of hours it takes for the helper to do it alone can be found as follows;

Time taken by both the gardener and the helper to complete the job=4

Work done by both the gardener and the helper in one hour = 1/4

Similarly,

Time taken by the gardener to complete the job = 5

Work done by the gardener in one hour = 1/5

The number of hours it takes for the helper alone can be calculated by subtraction. Subtracting the fraction done by the gardener in 1 hour from the fraction done by both the gardener and the helper in 1 hour;

1/4 - 1/5

As the common denominator is 20, we multiply 1/4 by 5 and 1/5 by 4.

5/20 - 4/20 = 1/20

The number of hours it takes for the helper to do it alone can be found by finding the reciprocal of 1/20 which is equal to 20/1

20/1 = 20

Hence, the helper takes 20 hours to do it alone.

Answer:

Step-by-step explanation:

Solution of the equation for G is given as G =  Fr²/Mm

According to the question we have been given the formula for evaluating the value of F which is given as :

                           F = GmM/r²

Now we need to solve the equation for evaluating G. Which is given step by step as :

                        F = GmM/r²

Multiplying both the sides by r² we get

                       Fr² = GmM*r²/r²

                       Fr² = GmM

dividing both the sides by Mm we get

                        Fr²/Mm = GmM/Mm

                        Fr²/Mm = G

                   or, G =  Fr²/Mm

Hence the solution for G is given as   G =  Fr²/Mm

Step-by-step explanation:

The evaluation of the expression given in surd form is 6.

Surds are expressions that use a root symbol, such as a square root, or another root symbol. Since the decimals of irrational numbers do not finish or recur, they cannot be expressed accurately in decimal form, hence surds are used instead.

Surds, in mathematics, are square root values that cannot be factored into a whole number or an integer. Numbers that are surds are irrational numbers.

From the given expression, the cube root of 216 can be computed as:

Solving the problem as per a linear equation, the value of b is found to be 1/10.

A linear equation is a form of algebraic equation in which the highest value of a variable is always equal to 1. Such an equation forms a straight line when carved on a graph.

As provided, the given equation is,

1/b = 4/2b - 10

or, 1/b = 2/b - 10 (as 4/2 = 2 )

or, 1/b - 2/b = - 10

or, 1/b ( 1 - 2) = - 10

or, - 1/b = - 10, ( we are using cross multiplication )

so, b = 1/ 10 ( as a negative sign on both sides will be nullified)

The linear equation of the table is y = 5x + 2.

when x = 20, y = 102

when y = 42, x = 8

Linear equation can be represented in slope intercept form as follows;

y = mx + b

where

Therefore,

m = 17 - 12 / 3 - 2

m = 5 / 1

m = 5

Therefore, let's find the y-intercept using (2, 12)

y = 5x + b

12 = 5(2) + b

12 = 10 + b

b = 12 - 10

b = 2

Therefore, the linear equation is y = 5x + 2.

when x = 20

y = 5(20) + 2 = 100 + 2

y = 102

when y = 42

42 = 5x + 2

42 - 2 = 5x

5x = 40

x = 40 / 5

The tracts of land in the study are reforested using the previous best practice whose results are already known. Now, it is not known, how the proposed method of reforestrey to plant a variety of trees at different intervals would grow. So, the tracts of land of previous plant can serve as a standard to which comparisons can made as to whether the newly proposed method is performing better than the previous or not.

This study was conducted at the Agua Salud Project site located in the Panama Canal Watershed (9° 13 N′, 79° 47′ W, 33 m amsl) with an average rainfall of 2700 mm annually, 80% of which falls between May and mid-December. Mean daily maximum and minimum temperatures are 32 °C and 23 °C . The topography is characterized by short and steep slopes. Soils are silt clay to clay with pH values of 4.4 to 5.8 and have very low levels of both plant available and total phosphorus. The data were collected from the Agua Salud native species and T. grandis plantation, both established in 2008 and planted in the same 3 m by 3 m spacing configuration.

step 1: Absolute value inequality entered

     |14c+5| > 7

step 2: Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |14c+5|

For the Negative case we'll use -(14c+5)

For the Positive case we'll use (14c+5)

step 3:  -(14c+5) > 7

    Rearrange and Add up

     -14c > 12

    Divide both sides by 14

     -c > (6/7)

    Multiply both sides by (-1)

The slope intercept equation for a line that passes through the points (-2,4) and (3,-5) is y = -9/5x ₊ 2/5.

Given the points are:

P₁ = (-2,4) = (x₁ , y₁)

P₂ = (3,-5) = (x₂ , y₂)

Therefore, the equation of the line that passes through the above points is:

y = mx ₊ b , Will be the equation to arrive to at the very end, but we need m & b, the slope and the y-intercept.

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

= ( -5 - 4 ) / ( 3 - ( -2) ) = -9 / 5

∴ m = - 9/5

Using either P₁ or P₂, plug in one of their respective x- and y-values into:

y = -9/5 x + b

substitute (3,-5)

₋5 = (₋9/5)(3) ₊ b

₋5 = ₋27/5 ₊ b

₋5₊27/5 = b

₋ 25 ₊ 27/5 = b

b = 2/5

slope intercept equation:

y = mx ₊ b

y = -9/5x ₊ 2/5

Therefore, y = -9/5x ₊ 2/5 is the equation of the line that passes through both points (-2, 4) and (3, -5).
