Answer 1

Answer: I think the answer is 81, but I don’t have a good explanation.

Step-by-step explanation: if you can find the angle next to 12x-3 (D), and the angle of 8+15x they should equal 180 degrees.

Answer 2

The Triangle Exterior Angle Postulate states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

In the given problem, the exterior angle is < JDC, and its measure is equal to the sum of the measures of < (12x -3)° and < 32°.

We can set up the following equality statement to solve for the value of x, and find out the measure of < JDC:

m < JDC° =  < (12x -3)° + < 32°

< (8 + 15x)° = < (12x -3)° + < 32°

Subtract 8 from both sides:

8 - 8 + 15x = 12x - 3 + 32 - 8

15x = 12x + 21

Subtract 12x from both sides:

15x - 12x = 12x - 12x + 21

3x = 21

Divide both sides by 3 to solve for x:

3x/3 = 21/3

x = 7

To verify whether the value for x is correct, substitute x = 7 into the equality statement:

m < JDC° =  < (12x -3)° + < 32°

< (8 + 15x)° = < (12x -3)° + < 32°

[8 + 15(7)]° = [12(7) - 3]° + 32°

8° + 105° = 81° + 32°

113° = 113° (True statement). Therefore, the correct value for x = 7.

Therefore, the correct answer is C) m < JDC = 113°.

Oy = 4(x + 5)2 -3
Oy = 4(x – 5)2 + 3

Answers

Answer:

I think is The second one

Step-by-step explanation:

Option B is correct, the equation of the parabola in vertex form is y = 4(x - 5)² - 3.

What is Parabola?

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point and from a fixed straight line which is known as the directrix.

We can start by using the vertex form of the equation of a parabola, which is given by:

y = a(x - h)² + k

where (h, k) is the vertex of the parabola and a determines the shape and direction of the opening of the parabola.

We are given that the vertex is (5, -3),

Substitute h = 5 and k = -3:

y = a(x - 5)² - 3

We also know that the parabola passes through the point (6, 1), so we can substitute x = 6 and y = 1:

1 = a(6 - 5)² - 3

1 = a - 3

a = 4

Substituting a = 4 into the equation

y = 4(x - 5)^2 - 3

Hence, the equation of the parabola in vertex form is y = 4(x - 5)² - 3.

4 years ago a pint of milk

What is the percentage
increase of the cost of milk
over 4 years?

Answers

Given-

Cost of milk 4 years ago = £1.05

To find-

Percentage increase in cost

Solution-

Increase in cost = £ ( 1.26 - 1.05 )

→ £ 0.21

Percentage increase :-

[tex] \frac{0.21}{1.05} \times 100[/tex]

[tex]→ 20[/tex]

Therefore, Percentage increase of the cost of milk over 4 years is 20% .

You buy a movie ticket for $5.25 and popcorn for $2.98. You pay with a 10-dollar bill. How much change will you get back?

Answers

Answer: $1.77

=======================================================

Explanation:

Use of a calculator makes quick work of this type of problem

5.25 + 2.98 = 8.23

10.00 - 8.23 = 1.77

-----------

If you want to do this using mental math, then one trick is to do this:

Think of 2.98 as 3.00, then add this to 5.25 to get 8.25. Notice that we're 2 cents too high (because of the jump from 2.98 to 3.00), so we need to subtract 2 cents from 8.25 to get 8.23

So that's a fairly quick way to add those two numbers in your head. The more practice you get, the quicker it will happen.

As for the subtraction part, you have a number of routes. Possibly a quick way is to jump from 23 cents to 30 cents (plus 7), then jump from 30 cents to 100 cents (plus 70). Therefore, we have 7+70 = 77 as the overall jump to get us to the nearest dollar. But we'll need one more extra dollar to end up at $10 exactly.

In other words, the "plus 77 cents" portion only gets us from $8.23 to $9, so that's why we need that extra dollar in change. Therefore, we've computed $1.77

I apologize for being a bit wordy. Despite being a bit long-winded, this mental math should come fairly quickly after enough practice.
