Answer + Step-by-step explanation:

CE bisects AB

CE ⊥ AB

Then

CE is the perpendicular bisector of AB.

Therefore

CA = CB and DA = DB

…………………………………

we have :

CA = CB

DA = DB

CD is a common side of the two triangles ACD and BCD

Hence , ΔACD ≅ ΔBCD

⇒ ∠CAD ≅ ∠CBD.

Based on the calculations below, the weekly gross pay of John Pelson is $1,339.90.

Let G represents weekly gross pay. The gross pay can now be calculated as follows:

Net pay = G – FIT – SIT – CIT - Health insurance – Charity ……………….. (1)

Substitute all the relevant values into the equation (1) and solve as follows:

$972.11 = G – $185.00 – 0.05G – 0.02G – $64.00 – $25.00

$972.11 + $185.00 + $64.00 + $25.00 = G – 0.05G – 0.02G

$1,246.11 = (1 – 0.05 – 0.02)G

$1,246.11 = 0.93G

G = $1,246.11 / 0.93

G = $1,339.90

Answer:

x = sqrt(403)

Step-by-step explanation:

Use Pythagorean Theorem for right triangles

x^2 + 9^2 = 22^2

   x = sqrt 403

The transformation is (b) The graph will reflect across the y-axis and then shift 5 units down.

The missing phrase in the question is: "If f(x) = 2ˣ + 1 is modified as g(x) = 2⁻ˣ + 1 - 5"

The functions are given as:

f(x) = 2ˣ + 1

g(x) = 2⁻ˣ + 1 - 5

First, the function f(x) is reflected across the y-axis (this eliminates options a and c)

The rule of this transformation is

(x,y) ⇒ (-x,y)

So, we have:

f'(x) = 2⁻ˣ + 1

Next, the function f(x) is shifted down by 5 units (this eliminates options d)

The rule of this transformation is

(x,y) ⇒ (x,y - 5)

So, we have:

f''(x) = 2⁻ˣ + 1 - 5

By comparing the functions f"(x) and g(x), we have:

g(x) = f''(x) = 2⁻ˣ + 1 - 5

Hence, the transformation is (b) The graph will reflect across the y-axis and then shift 5 units down.

Using proportions, it is found that the number of cups per student is of 1.97. hence there will not be enough for each student to have 2 cups.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Each gallon is worth 16 cups, hence, since each grade is given 15 gallons of water, and the trip consists of three grades, the number of cups is given by:

C = 3 x 15 x 16 = 720.

There is a total of 370 students, hence the number of cups per student is given by:

P (blue) = 23 / 82

Step-by-step explanation:

There are 23 blue out of 82 (28 + 21 + 23 + 10 = 82) balls

or,

Answer:

25

Step-by-step explanation:

When multiplying a whole number by a fraction, the first step is to multiply the whole number by the numerator. Then, you divide by the denominator. For example, on the left side, 5 x 5 = 25. You are left with 25/6. Finally, when you divide by 6, you are left with 4.166.....

If the denominator is the same (6) on both sides, to get the same answer, you somehow need to get the numerator (25) the same. So, what whole number can be multiplied by 1 to get 25? This number is 25. Therefore, the missing number is 25. This answer is correct because 25 x 1 = 25. You would be left with 25/6 and get a final answer of 4.166....

The statement that is true for ΔXYZ and ΔX''Y''Z'' is; 2: ΔXYZ and ΔX''Y''Z'' are congruent

We are told that;

- Triangle XYZ is rotated 90º clockwise about the origin to form triangle X'Y'Z'.

- Thereafter, reflected across the x-axis to form triangle X''Y''Z''

Now, in transformation, Reflection is flipping an object across a line without changing its size or shape while Rotation is rotating an object about a fixed point without changing its size or shape. Thus, it means that the size and shape of the triangle formed is not different from the original one.

Thus, we can say that both triangles are congruent because the shape and size didn't change.

Answer:

  a)  ΔCED ~ ΔCAB

  b)  157.5 m

Step-by-step explanation:

The similarity statement for geometric figures lists the corresponding vertices in the same order. Corresponding sides of similar figures are proportional. That fact can be used to find the missing side length.

__

The right angles are corresponding. Angle C corresponds to itself, so the similarity statement can be written ...

  ΔCED ~ ΔCAB

__

Corresponding sides are proportional, so we can write ...

  AB/AC = ED/EC

  AB/(50+160) = 120/160 . . . . . using the numerical values

  AB = 210 × 120/160 = 157.5 . . . meters

The length of the lake is 157.5 meters.

The mean and median of the given set of data are respectively; The mean age is 38.28. The median age is 38.

The mean simply means the average of the set of data. Thus;

Mean = ∑x/n

∑x = 22 + 24 + 28 + 28 + 30 + 31 + 31 + 32 + 32 + 35 + 36 + 37 + 38 + 41 + 42 + 42 + 44 + 44 + 45 + 46 + 46 + 47 + 47 + 49 + 50

∑x = 957

Mean = 957/25

Mean ≈ 38.28

B) Median is the midterm when arranged in ascending order. When we arrange in ascending order, we get;
