Answer:

x = 7

Step-by-step explanation:

You need to figure which sides correspond and set up the proportions

Labeling the vertices of the triangles would help you.

I did that and found that 5x - 15 ↔ 10 since both of those sides are opposite the 42° angles and 36 ↔ 18

So [tex]\frac{5x - 15}{10} = \frac{36}{18\\}[/tex]

18(5x - 15) = 10(36)

90x - 270 = 360

90x = 630

x = 7

Answer:

344 visitors

Step-by-step explanation:

Given that the relationship between the number of visitors to a museum(y) and the daily rainfall in mm(x) is defined as

y=14.1x+62.0

when the daily rainfall is 20 mm, the number of visitors

y = 14.1(20) + 62

= 282 + 62

= 344

It means that the expected number of visitors is 344 persons (to the nearest integer).

Answer:

a = 72° b = 88°

Step-by-step explanation:

We know in the cyclic quadrilateral opposite angles are supplementary so

a + 108° = 180° { being opposite angles of cyclic quadrilateral }

a = 180° - 108°

a = 72°

b + 92° = 180° { being opposite angles of cyclic quadrilateral }

b = 180° - 92°

b = 88°

Answer:

Figure B

Step-by-step explanation:

A translation does not "flip" the position of the pre-image. Figure C is a reflection of figure A.

A translation would "slide" the figure into a new position without mirroring nor rotating it.        

Figure B should be the translation of Figure A.

Hope this helps.

Figure B is the translation of figure A by 2 units up.

If a graph is translated and rotates by any amount either in x and y direction then it will be transfomation of the graph.

For example transformation of graph f(x) by 2 units down.

The new resultant graph could be only translated or rotated or both.

Given figure A

If we look at C then the face of this is towards the right but in figure A the face is towards the left.

So it means C will translate + rotation of graph A it will not be pure translation.

In figure B it is clear that it is a translation of figure A by 2 units upward.

Hence "Figure B is the translation of figure A by 2 units up".

Answer:

The answer is

[tex]y = - 7[/tex]

Answer:

y = -7

Step-by-step explanation:

Hey :)

y = mx + b

*m is equal to the slope...

y = (0)x + b

Plug in the point you have...

-7 = (0) (5) + b

-7 = 0 + b

-7 = b

y = (0)x - 7

y = -7

Ignore the (0)x because anything multiplied by 0 is 0 so there's no point in having 0x in your equation.

Answer: y = -7

Answer:

The range of values of [tex](f + g)(x) \ge 3[/tex] is for all values of x [tex]-\infty[/tex] to [tex]+\infty[/tex]

Step-by-step explanation:

Given

[tex]f(x) = |x| + 9[/tex]

[tex]g(x) = -6[/tex]

Required

Describe the range of [tex](f+g)(x)[/tex]

First, calculate [tex](f+g)(x)[/tex]

[tex](f+g)(x) = f(x) + g(x)[/tex]

Substitute values for f(x) and g(x)

[tex](f+g)(x) = |x| + 9 -6[/tex]

Evaluate Like Terms

[tex](f+g)(x) = |x| + 3[/tex]

The above expression shows that [tex](f + g)(x) \ge 3[/tex]

Because [tex]|x| \ge 0[/tex]

Hence, the range of values of [tex](f + g)(x) \ge 3[/tex] is for all values of x [tex]-\infty[/tex] to [tex]+\infty[/tex]

Answer:

a minimum of $1,200

Step-by-step explanation:

The flexible spending accounts (FSA) and health savings accounts (HSA) are basically accounts that help pay for your medical bills and therefore, drastically reduce the total amounts that you would have to pay out-of-pocket. Therefore, in this scenario, if Mason does not use an FSA or HSA then he would have to make a minimum of $1,200 to completely pay off his medical bill in full. Otherwise, he would still owe money.

Answer:

48: 0.48

8: 0.667

I hope that answers your question and it's right!! :)

Answer:

0.2, .48, 8.0

Step-by-step explanation:

Answer:

Step-by-step explanation:

So you know that distance = rate x time.

9 miles in 1.5 hours

In this case, you know the time (1.5 hours) and the distance (9 miles)

(You can ignore the rest of the chart since the question is just about running.)

What's missing is the rate (r) at which you ran. (Think of it as speed...)

If r x t = d, that means that d ÷ t = r

So plug in what you have: 9 ÷ 1.5 = your rate. And 9 ÷ 1.5 is...

6

So you ran 6 miles per hour. And you can check it: if you went 6 miles in one hour, you could go another 3 miles in another half an hour. That would be 9 miles in 1.5 hours. Check!

Answer:

25 degrees

Step-by-step explanation:

So a triangles angels equal 180 degrees

So for angel ECD 180 - (15+90) = 75

Straight lines also always equal to 180 degrees so

180 - (80+75) = 25

Measure of ∠BCE = 25° .

A figure which is formed by two rays or lines that shares a common endpoint is called an angle. The word “angle” is derived from the Latin word “angulus”, which means “corner”.

Given, In figure,

∠CED = 15°

∠EDC = 90°

∠BCA = 80°.

In triangle ECD

Sum of all interior angles of a triangle is 180°

∠ECD +∠CED +∠EDC = 180°

∠ECD + 15° + 90° = 180°

∠ECD = 180° - 105°

∠ECD = 75°

Now,

∠BCA,∠BCE and∠ECD are at point C on line AD.

Sum of all angles made at one point of line is 180°.

∠BCA +∠BCE +∠ECD = 180°

80° + ∠BCE + 75° = 180°

∠BCE = 180° - 155°

∠BCE = 25°

Hence, 25° is measure of ∠BCE.

Answer:

Acceleration, [tex]a=4\ m/s^2[/tex]

Step-by-step explanation:

Given that,

Initial speed = 4 m/s at 2 seconds

Final speed = 32 m/s at 9 seconds

We need to find car's average acceleration. We know that average acceleration is equal to the change in speed divided by the change in time. So,

[tex]a=\dfrac{v_2-v_1}{t_2-t_1}\\\\=\dfrac{32-4}{9-2}\\\\=\dfrac{28}{7}\\\\=4\ m/s^2[/tex]

So, the car's average acceleration is equal to [tex]4\ m/s^2[/tex].
