The similarity statement that would be true for the given figure is; A.

∆ DAB ~∆ DAC

Similar triangles are those triangles that have the same proportionate side lengths as well as related angle measurements.

Two triangles are said to be similar if their corresponding angles and sides have the same ratio. Similar triangles will possess the same form but may or may not have the same size.

The SAS similarity rule states that If the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle inscribed by the two sides in both the triangle are equal, then it means that the two triangles are similar.

The Side-Side-Side (SSS) similarity rule states that If all the three sides of a triangle are in proportion to the three sides of another triangle, then the two triangles are similar.

In this question, when we analyze the triangles well, it is clear that;

DA is congruent to itself by reflexive property of congruence.

Thus, we can say that ΔDAB is similar to ΔDAC,

Answer:

53.33%

Step-by-step explanation:

There are a total of 4 + 3 + 8 = 15 coins in the jar. If we want to find the probability that the coin will not be a penny or a nickel, we need to find the number of coins that are not pennies or nickels, and divide that by the total number of coins in the jar.

The number of coins that are not pennies or nickels is 8 dimes. Therefore, the probability that the coin will not be a penny or a nickel is:

8 / 15

This simplifies to:

0.5333 or 53.33%

Therefore, the probability that the coin will NOT be a penny or a nickel is approximately 0.5333 or 53.33%.

Answer:

Since a and b are parallel

Step-by-step explanation:

2x+27=3x - 27

collect the like terms

3x-2x=27+27

x=54

PLS MARK BRAINLIEST

Answer:

x = 54

Step-by-step explanation:

If the lines are treated as parallel , then

(3x - 27) and (2x + 27) are alternate exterior angles and congruent, so

3x - 27 = 2x + 27 ( subtract 2x from both sides )

x - 27 = 27 ( add 27 to both sides )

x = 54

For a and b to be parallel then x = 54

The derivative of of f(x) = 10 is 0

The derivative of a function is the measure of the rate of change of the function. They are fundamental to the solution of problems in calculus and differential equations.

Here the function is not changing as 10 is a constant. So, if f(x) = c where c is a constant then f'(x) = 0 as the derivative of a constant is always zero.

Mathematically:

           d(f(x))/dx = \(\lim_{h \to 0}\) (f(x+h) - f(x))/h

There  is no x to substitute for x + h so no difference is noticed:

             \(\lim_{h \to 0}\) (f(x+h) - f(x))/h =   \(\lim_{h \to 0}\) (10 - 10)/h = 0

Hence, the derivative of f(x) = 10 is 0

Answer:

120 + b = 312

Step-by-step explanation:

...

In order to determine whether f'(t), the derivative of the temperature function f(t), is positive or negative, we need more information about the specific function f(t). Without additional details or the form of the function, we cannot determine the sign of the derivative.

The derivative f'(t) represents the rate of change of the temperature with respect to time. If f'(t) is positive, it means the temperature is increasing over time. If f'(t) is negative, it means the temperature is decreasing over time. However, without knowing the specific form or characteristics of the function f(t) that describes the temperature, we cannot determine the sign of the derivative. The sign of the derivative depends on the behavior of the function, such as whether it is increasing or decreasing, concave up or concave down, or has any specific patterns or constraints. To determine whether f'(t) is positive or negative, we would need additional information about the function, such as its formula, behavior, or constraints.

Answer: The slope of the line passing through the points (1,-1) and (4,3) is 4/3

Explanation:

The two points marked on the green line are (1,-1) and (4,3)

Let's use the slope formula.

\((x_1,y_1) = (1,-1) \text{ and } (x_2,y_2) = (4,3)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{\text{y}_{2} - \text{y}_{1}}{\text{x}_{2} - \text{x}_{1}}\\\\m = \frac{3 - (-1)}{4 - 1}\\\\m = \frac{3 + 1}{4 - 1}\\\\m = \frac{4}{3}\\\\\)

The slope is 4/3

slope = rise/run = 4/3

rise = 4

run = 3

It means "go up 4 and to the right 3" so we can move from (1,-1) to (4,3).

System of Equations

c + r = 32 ..... Equation 1

2c + 4r = 72......... Equation 2

We have 28 chickens and 4 rabbits

Step-by-step explanation:

Let the number of chickens be represented by c

The number of rabbits be represented by r

From the question, John counts:a total of 32 heads

32 heads = a total of 32 animals

Hence:

c + r = 32....... Equation 1

c = 32 - r

Also, John counts:

A total of 72 legs in his backyard.

Chickens have: 2 legs

Rabbits have: 4 legs

Hence:

2c + 4r = 72......... Equation 2

System of Equations is:

c + r = 32 ..... Equation 1

2c + 4r = 72......... Equation 2

Lets us substitute 32 - r for c in Equation 2

2(32 - r) + 4r = 72

64 - 2r + 4r = 72

Collect like terms

- 2r + 4r = 72 - 64

2r = 8

r = 8/2

r = 4

This means we have 4 rabbits

Note:

c = 32 - r

r = 4

c = 32 - 4

c = 28

Hence, we have 28 chickens

Point M is the midpoint of segments LO and CG.

That makes segments CM and GM congruent (side).

Then angles CML and GMO are congruent since they are vertical angles (angle).

Finally, segments LM and OM are also congruent because of the midpoint (side).

Therefore, the original multiplication problem that Mrs. Shen should write for her fourth grade math class is: 22 x 56 = 1232

To solve this problem, we need to understand the distributive property of multiplication. The distributive property states that when we multiply a number by a sum, we can distribute the multiplication to each term in the sum.
In this case, Mrs. Shen wants her students to expand two 2-digit numbers being multiplied together, and the expanded form of the product is given as:
(20 x 50) + (20 x 6) + (2 x 50) + (2 x 6)
We can simplify this expression by multiplying the factors:
1000 + 120 + 100 + 12
= 1232
Therefore, the product of the two 2-digit numbers being multiplied together should be 1232.

To find the original multiplication problem, we can use the distributive property to write 1232 as the product of two 2-digit numbers:
1232 = (20 + 2) x (50 + 6)

Step-by-step explanation:

Here, we want to calculate the percentage increase in the value of the shares

Let the original value of the shares bought be $x

It decreased by 10%

Mathematically,

that will be x - (10% of x)

= x -0.1x = 0.9x

This is the new value

It increased at this point by 20%

The new value will be;;

0.9x + (20% of 0.9x)

0.9x + 0.18x

= 1.08x

The percentage increase in the shares will be;

(1.08x - x)/x * 100%

= 0.08x/x * 100% = 8%

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

The set of ordered pairs (x, y) where f(x)=y makes up a function's graph in mathematics. These pairs, which are Cartesian coordinates of points in two-dimensional space and thus constitute a subset of this plane in the typical case where x and f(x) are real numbers, are examples of real numbers.

Instead of the pairs ((x,y),z) as in the definition above, the graph in the context of functions of two variables, i.e. functions whose domain consists of pairs (x,y), typically refers to the set of ordered triples (x,y,z) where f(x,y)=z.
