This is solving special right triangles (45, 45, 90, and 30, 60, 90) and some sides have radicals ANSWER IN RADICAL FORM

Answer:

Since there is a  8

in the hundredths place, the number in the tenths place will

round up

. Since 9 + 1 = 10, a

1 will go in the tenths place and the

1

will be added to the 7 in the ones place making the answer 8

• x+y = 4

• 2x+3y= 6.

• x and y.

• x+ y = 4

=> x = 4 - y

put x in :

• 2x + 3y = 6

=> 2 (4-y)+3y = 6

=> 8 - 2y +3y = 6

=> y = 6 - 8

=> y = -2 .

Now, put y in x+y= 4.

=> x+(-2)= 4

=> x - 2 = 4

=> x = 4+2

=> x= 6.

Hence, the value of x is 6 and y is -2.

I hope it will help you.

Regards.

Answer:

Walmart

Step-by-step explanation:

It is given that,

Jonathan wants to buy his whole basketball team new clothes.

On Amazon there is a sell for 11 shirts for $145.23

The cost of 1 shirt on amazon:

[tex]C=\dfrac{145.23}{11}=\$13.20[/tex]

On Walmart sell for 23 shirts for $212.19.

The cost of 1 shirt on Walmart:

[tex]C=\dfrac{212.19}{23}=\$9.225[/tex]

Cost of 1 shirt on Amazon is $13.20 and on Walmart is $9.225. It is clear that on Walmart it is better to buy for $9.225.

Answer:

y=1/5(x+8)-9

Step-by-step explanation:

Point Slope Formula: y=m(x-x1)+y

y=1/5(x+8)-9

Answer:

[tex]y+9=\frac{1}{5} (x+8)[/tex]

Step-by-step explanation:

We are given that a line has a slope (m) of 1/5, and passes through the point (-8, -9).

We want to write the equation of this line in point-slope form.

Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.

As we are given both the slope and the point, we can plug those values into the equation.

Starting with the slope, we can replace m with 1/5.

[tex]y-y_1=\frac{1}{5} (x-x_1)[/tex]

Now, substitute -8 as [tex]x_1[/tex] and -9 as [tex]y_1[/tex]. We get:

[tex]y--9=\frac{1}{5} (x--8)[/tex]

This can be simplified to:

[tex]y+9=\frac{1}{5} (x+8)[/tex]

Step-by-step explanation:

Answer:

3^6

Step-by-step explanation:

Answer:

3-16 is your answer

Answer:

280 adult tickets

130 student tickets

190 children tickets

were sold at the concert

Step-by-step explanation:

Let the number of students be s , adults a and children c

Total 600;

Thus;

a + s + c = 600 •••••••(i)

let us look at revenue

Revenue = number * ticket price

For adults; a * 7 = $7a

For students ; s * $3 = $3s

For children; c * $2 = $2c

Total is 3150

thus;

7a + 3s + 2c = 3150 ••••••••(ii)

150 more adults than students;

a = s + 150 ••••••(iii)

Substitute iii into ii and i

into ii

7(s + 150) + 3s + 2c = 3150

7s + 1050 + 3s + 2c = 3150

9c + 3s = 3150-1050

9c + 3s = 2,100 •••••••(x)

Substitute into i

a + s + c = 600

s + 150 + s + c = 600

2s + c = 600 - 150

2s + c = 450

c = 450 - 2s ••••••(xx)

Now substitute xx into x

9(450-2s) + 3s = 2100

= 4050-18s + 3s = 2100

4050-2100 = 18s - 3s

15s = 1950

s = 1950/15

s = 130

c = 450 -2s

c = 450 - 2(130)

c = 450 - 260

c = 190

a = 150 + s

a = 150 + 130

a = 280

Answer:

m = 2/5

Step-by-step explanation:

If you look carefully you see that each new y value is obtained by adding 2/5 to the previous one.  That 4/5 came from adding 2/5 to 2/5.

If we move from x = 0 to x = 1, y increases from 6/5 to 8/5.

Thus:  the "run" is 1; the "rise" is 2/5.

Thus, the slope is m = rise / run = 2/5 divided by 1, or just m = 2/5

Answer:

a.) 0.468

b.) -0.075

c.) 0

Step-by-step explanation:

Given the distribution :

Z~N(μ = 0,σ = 1)

Distribution = normal

Mean (μ) = 0

Standard deviation (σ) = 1

a) Find x so that P(Z ≤ x) = 68%

Using the z probability calculator : Zscore corresponding to 68% = 0.68 = 0.468

Usingbthe relation :

Zscore = (x - m) / σ

0.468 = (x - 0) / 1

0.468 = x - 0

x = 0.468

b) Find the data value x at the 47th percentile

47th percentile = Zscore of - 0.075

Zscore = (x - m) / σ

-0.075 = (x - 0) / 1

-0.075 = x - 0

x = -0.075

c) Find the data value x at the 50th percentile

50th percentile = Zscore of 0.0

Zscore = (x - m) / σ

0.0 = (x - 0) / 1

0.0 = x - 0

x = 0

Answer:

The answer is "12"

Step-by-step explanation:

Let f(x) be the function, where x specified in a certain section by the series of queries that have been addressed also as function.

[tex]\to f(12)=18[/tex] it implies, that even a test the person gets 18 points to packed up x queries. Its right series of issues were also:

[tex]\to f(x) = f(12)[/tex]

Therefore x = 12, The correct number of questions in the segment.
