Answer:

20 dollars

Step-by-step explanation:

I think 20+20+20=60 then 60-40=20

Answer:

$95.4

Step-by-step explanation:

6% in decimal form is 0.06

we need to find what 6% of 90 is to see how much sales tax there is on this item

0.06*90=5.4

the sales tax is 5.4

5.4 is 6% of 90 so we need to add 5.4 to 90

90+5.4=95.4

$95.4---total amount noah paid(normal price+ sales tax)

Answer:

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

Answer:

No. Similar triangles only have equivalent angles. Congruent triangles have equal side lengths.

Answer:

The equation is y = 5x + 4.

Step-by-step explanation:

☆Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

☆Slope-intercept: [tex]y = mx + b[/tex]

---

☆We need to find the slope first. So just plug in according to the slope formula!

[tex]m = \frac{9 - 4}{1 - 0} = \frac{5}{1} = 5[/tex]

---

☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.

[tex]y = mx + b \\ 9 = 5(1) + b \\ 9 = 5 + b \\ \frac{ - 5 = - 5 \: \: \: \: \: \: \: \: \: \: \: \: }{4 = b \: \: \: \: \: \: \: \: \: } [/tex]

---

☆Now all we need to do is plug in and we are done!

[tex]y = 5x + 4[/tex]

The first method is substitution. This is when the x or y value that is known is substituted into one of the equations. This should be done when you can easily see or find the x or y value.

Example: x = 3, and x + 8y = 30.

The x was given in the first equation (x = 3), and can therefore be substituted into the other equation to find y.

The next method is elimination. This is when you add the two systems together and eliminate either the x values or the y values. This should be done when there are opposite signs of the same number in both equations.

Example: y - 3x = 24, and 2y + 3x = 7

In the first equation you have -3x, and in the second you have 3x. If you were to add the two equations, the x values would cancel out and you would be left with:

y + 2y = 24 + 7

And then you could solve for y.

The last method is to graph both equations and to see at which point the lines intersect.

Answer:

[tex]P_x=0.7407407407 \approx 0.74[/tex]

Step-by-step explanation:

From the question we are told that

Dice rolls n=200

Number of dice =2

Generally sample space for Two 6-sided dice is [tex]n=36[/tex]

The sums of five bears the following events

[tex]E={(1,4)(2,3)(3,2)(4,1)}=>4[/tex]

Probability of getting a sum of 5 in a roll

[tex]P(sum 5)=\frac{4}{36}[/tex]

Generally the probability that two dice rowed will include 30 sums of 5

[tex]P_x=\frac{4(200)}{36(30)}[/tex]

[tex]P_x=0.7407407407 \approx 0.74[/tex]

The probability of getting more than 30 sums of 5 out of 200 rolls is 1/6.

Probability is the measurement of possibilities.

Number of rolls =200

Number of dice =2

Sample space for a sum of 5 will be (1,4) (2,3), (3,2),(4,1)

Total outcomes = 36

So, the probability of getting 5 as a sum in a single roll= 4/36 =1/9

So, the probability of getting more than 30 sums of 5 out of 200 rolls

= 1/9 *30/200

=1/6

Hence, the probability of getting more than 30 sums of 5 out of 200 rolls is 1/6.

Answer:

B, (-1/3, 3)

Step-by-step explanation:

Answer:

hi!

Step-by-step explanation:

Let us assume that the missing side of the triangle is x.

Therefore,

By Thale's Theorem,

RE/RT = RD/RS

24/36 = 18/x

x = 36.18/24

x = 27

Therefore, the missing side of the Triangle is 27 units/cm

Answer:

  y = 0.2·0.5^x

Step-by-step explanation:

An exponential function is generally of the form ...

  y = a·b^x

where 'a' is the function value when x=0, and b is the ratio between values for x=1 and x=0.

In the given table, y = 0.2 for x = 0, so a = 0.2.

We find that the value for x = 1 is 0.1, so the value of b is ...

  b = 0.1/0.2 = 0.5

Then the exponential function is ...

  y = 0.2·0.5^x

Answer:

[tex]y=-8x-61[/tex]

Step-by-step explanation:

The slope-intercept form of the equation is y=mx+b where m is the slope and b is the y intercept. We know so far, that the slope is -8. We plug that in for m.

[tex]y=-8x+b[/tex]

Now, we need to find the y-intercept. The question gives us the point (-7,-5). We plug in -7 for x, and -5 for y.

[tex]-5=-8(-7)+b[/tex]

Then, we solve.

[tex]-5=56+b[/tex]

Subtract 56 from both sides.

[tex]-61=b[/tex]

Finally, we get this equation:

y=-8x-61
