Hw Assignment. What Is Wrong?

Answers

Answer 1
On the second step, the student said x - x is 2x, when it should equal 0
The second step should read
6x - 5 = 7
The student should then add 5 to each side
6x = 12
The student should then divide by 6 on both sides
x = 2
Answer 2

Answer:

the second and first steps. in the second part, x, should be substracted by x

so no xz should remain in the second part of the equation.

the second step would be:

6x - 5 = 7

Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value

Answers

Answer:

x = 16°

Step-by-step explanation:

We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°

∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)

∠ACD = x, ∠DCE = 148,  ∠ECD = x

substituting the respected values for the angles gives:

x + 148 + x = 180

2x + 148 = 180

subtracting 148 from both sides:

2x + 148 - 148 = 180 - 148

2x = 32

Dividing both sides by 2, to get x:

2x/2 = 32/2

x = 16°

The function y = -16t+^2 40 represents the height y (in feet) of a water droplet t seconds after falling from an icicle. After how many seconds does the water droplet hit the ground? Round your answer to two decimal places. ​

Answers

Answer:

The water droplet will hit the ground 1.58 seconds after it started falling.

Step-by-step explanation:

The function:

y = -16*t^2 + 40

represents the height of a water droplet t seconds after falling from an icicle.

We want to find the value of t such that the water droplet hits the ground, and this will happen when y = 0.

Then we only need to solve the equation:

0 = y =  -16*t^2 + 40

0 =  -16*t^2 + 40

16*t^2 = 40

t^2 = 40/16

t = √(40/16) = 1.58

The water droplet will hit the ground 1.58 seconds after it started falling.

3x+30=180 degrees, what is the value of the letter x in this problem?

Answers

Answer:

50

Step-by-step explanation:

180-30=150/3=50

3x + 30 = 180

     -30     -30     subtract 30 on both sides, solve for 180 - 30 which is 150.

___________

3x = 150

__    ___       divide 3 on both sides, solve for 150 ÷ 3 which is 50.

3       3

x = 50, final answer

the answer is 2

Step-by-step explanation:

The equation which represent the three squares which is divided into the 5 fifths is,

What is a multiple of fraction?

A fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,

[tex]\dfrac{a}{b}[/tex]

Here (a) is the numerator and (b) is the denominator.

A multiple of a fraction is the number which is n times of the original function.

The model represents,

[tex]3 \div 1/5[/tex]

Here, the total number of square are given is 3. These three square are then divided into the one fifth.

Thus, we get total 3 times of 5 one fifth which is equal to the entire 3 squares

.

Thus, the equation can be written for this condition as,

[tex]15 \times \dfrac{1}{5} = 3[/tex]

Hence, the equation which represent the three squares which is divided into the 5 fifths is,

[tex]15 \times \dfrac{1}{5} = 3[/tex]

Option B is the correct option.

The Answer is : 20.15
Theres an easier way. Pythagorean theorem-
A^2+B^2=C^2
A and B are legs while C is the hypotenuse or slanted one.
So rearrange formula.
C^2 - A^2=B^2
1225 - 441 = B^2
784= B^2

What is a right-angle triangle?

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

A right-angle triangle has sides with lengths 200 ft and 200 ft.

By Pythagoras theorem, we have

H² =  P² + B²

H² = 200² + 200²

H² = 40000 + 40000

H² = 80000

H  = 200√2

H  = 282.84 ft

Alma is going to walk through the park from Point A to Point B is 282.84 ft.

3960 * cos(60.183) = 1969       some number in relation to the distance to the poles

2 * pi * 1969 = 12371.8

In triangle ABC, the measure of angle CAB is 80° and the measure of angle ABC is 45.5°. What is the measure of angle BCA in degrees? A 125.5°125.5 degrees B 54.5°54.5 degrees C 55.5°55.5 degrees D 64.5°

Answers

Answer:

B 54.5°

Step-by-step explanation:

Since we have a triangle,

CAB + ABC + BCA = 180 (sum of angles in a triangle)

Since CAB = 80° and ABC = 45.5°, substituting these into the equation, we have

80° + 45.5° + BCA = 180°

simplifying, we have

125.5° + BCA = 180°

collecting like terms, we have

BCA = 180° - 125.5°

BCA = 54.5°

So, the answer is B

Answer:

15.95 feets

Step-by-step explanation:

Given that:

Angle of elevation = 62°

Using trigonometric relation :

Tanθ = opposite / Adjacent

From the drawing attached :

Opposite = 30 feets

Distance between girl and lighthouse = d

Tan 62 = 30 / d

1.8807264 * d = 30

d = 30 / 1.8807264

d = 15.951283

d = 15.95 feets
