y = 7

Step-by-step explanation:

Given that ∆CAB ≅ ∆CDB, you can use CPCTC [corresponding parts of congruent triangles are congruent] to evaluate the given lengths and angle measures, to show that the corresponding measures are the same for both triangles. Using the triangle sum theorem which states that all angles in a triangle must add up to 180°, you can find ∠ACB.

If ∠CAB = 70°, and ∠ABC = 60°,

∠ACB = 50° because ∠CAB + ∠ABC + ∠ACB = 180°.

∠CAB + ∠ABC + ∠ACB = 180° →

∠ACB = 180° – ∠CAB – ∠ABC

∠ACB = 180° – 70° – 60°

∠ACB = 50°

70° + 60° + 50° = 180°.

Remember, the order of the letters in the angle are very important because it corresponds to the parts of the angle that make up the vertex which is the middle letter, along with the first and last letters which are the endpoints.

Because ∆CAB ≅ ∆CDB,

∠ACB ≅ ∠DCB [CPCTC].

As indicated in the problem, ∠DCB = (x² + 16x)°.

Because ∠DCB ≅ ∠ACB = 50°,

(x² + 16x)° = 50°.

So this can be completed as a square by converting this into vertex form.

x² + 16x = (x + 8)² – 64.

Then, (x + 8)² – 64 = 50.

(x + 8)² – 64 + 64 = 50 + 64 →

(x + 8)² = 114 →

(x + 8) = ±√114 →

x = -8 ± √114 [one more step]

[The measure must be positive so the expression must be added]

x = -8 + √114.

what is 1/4 written as a percent?

Answers

Answer:

25%

Step-by-step explanation:

1/4 = 25/100

and that fraction as a decimal is .25, which is equal to 25%

The fraction number 1/4 in the form of a percentage will be 25%.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The fraction number is 1/4. Then, convert the fraction number into a percentage, then we have

P = (1/4) x 100

P = 0.25 x 100

P = 25%

The fraction number 1/4 in the form of a percentage will be 25%.

Brianna walks at a steady rate of 3.5 miles per hour. Write a direct proportion equation based on this statement. Identify all variables and the constant of proportionality. Explain what the constant of proportionality means in this situation

Answers

Answer:

Step-by-step explanation:

Based on the information provided we can create the following direct proportion equation...

D = 3.5x

In this equation, the variable D represents the distance that Brianna has walked while the variable x represents the number of hours she walked. In this equation, the constant of proportionality would be the 3.5 miles that Brianna walks per mile. This value affects the entire equation because it is multiplied by the number of hours Brianna walks which is directly proportional to the Distance she travels, as one value increases so does the other.

Answers

Given:

Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster.

To find:

The graph that represents the set of heights that satisfy this requirement.

Solution:

Let x be the height required for the ride.

Guests must be at least 54 inches tall to be able to ride the roller coaster. It means required height is greater than or equal to 54.

[tex]x\geq 54[/tex]

So, 54 and all values above 54 are in the solution set.

Since, 54 is included in the solution set, therefore there is a closed circle at 54. All values above 54 are in the solution set, so everything to the right of the circle is shaded.

Therefore, the correct option is C.

Multiply through by 6 ( the LCM of 6 and 3 ) to clear the fractions

- 5(8 + 5b) = 450 + 10b ← distribute left side

- 40 - 25b = 450 + 10b ( subtract 10b from both sides )

- 40 - 35b = 450 ( add 40 to both sides )

- 35b = 490 ( divide both sides by - 35 )

b = - 14

i think it’s b= -14
