Answer:

I think Vivek is 20 and his father is 50

Because 30 + 30 equals 60 as he has to be half his age he'll be 30 but that's in 10 years time. you just subtract 30 and 60 by 10 and you'll get 20 and 50

Answer:

Vivek:20 years

Father:50 years

Step-by-step explanation:

Since it is a age question, their difference do not change, so

2-1=1 (difference in ratio)

1u=30

Vivek now:30-10=20 years

Father: 30x2=60

60-10=50 years

Hope this helps! Thanks.

Number 1 explanation= this is LCM so first LCM blank box to devided is 2 and 2nd box also 2.

Answer:

Step-by-step explanation:

The general linear equation:

[tex]y = mx+b[/tex], m is slope, b is y-intercept

Plugging the points that satisfy the line:

[tex]3 = 9m + b[/tex]

[tex]-7=-7m+b[/tex]

Subtracting the equations from each other:

[tex]10 = 16m\\m= \frac{10}{16} = \frac{5}{8}\\[/tex]

Plugging m to any of the equations:

[tex]3= \frac{45}{8} + b \\b=-2.625\\[/tex]

Therefore, the equation is:

[tex]y=0.625x-2.625[/tex]

Answer: b. 2

Answer:

Given that, figure LMNO and figure PQRS are similar

So, RQ / MN = SP / OL

Answer:

divide both sides by 2

yes, it is in slope intercept form.

the slope is 1/2

[tex]2y=x+4[/tex]

Divide by 2

[tex]2y/2 = x/2 + 4/2[/tex]

[tex]y=\frac{1}{2} x +4[/tex]

The equation is now in intercept form

The slope of the line is [tex]\frac{1}{2}[/tex]

Answer:

[tex]x = 10°[/tex]

[tex]z = 66°[/tex]

Step-by-step explanation:

[tex](9x - 24)° + (12x - 6)° = 180°\\21x° - 30° = 180° \\ 21 x° = 180° + 30° \\ 21x° = 210° \\ x° = \frac{180°}{30°} \\ x° = 10°[/tex]

z° = 9x - 24 ( vertically opposite )

z° = 9(10) - 24

z° = 90 - 24

z° = 66°

Answer:

x° = 10°

z° = 66°

Answer:

İt is solved by using derivative

The edges of box are 20–2x,15–2x and x

Volume=(20–2x).(15–2x).x

İf you take derivative and then find the roots of derivative we obtain exstramum points that means these values make volume maximum or minimum

But

Answer is not rational

Answer:

A = 300-x^2 for area

A = 20L * 15 -x^2   for area

20L - x^2 = 300 - x^2 /15 -x^2 could also work to find length .

SIMPLIFIED

L - x = 300/20 -  ( x^2 )/ 15 - x

Step-by-step explanation:

Length = L = 20 inches.

Area of one side = A = 15 X 20 = 300 cm^2

= 300 - x^2  

This means the missing corner square is also squared

Simplifies to sqrt 300 - x

but as length was asked 20L * 15 -x^2

we know one side may be 15x 15

and if one side is 15 x 20

then instead of 15 x 15 it may be 15 x 20

eitherway we are looking at one side representing area of one side of the box. 300-x is our answer.

Answer:

x = 11/10

Step-by-step explanation:

5x + 5x -7 = 4

10x-7 = 4

×=11/10

add 7 to both sides of the equation

simplify

divide both sides of the equation by the same term

simplify

Answer:

69,660,000/258,000,000

Step-by-step explanation:

If you do part/whole = %/100 and solve that:

100 can go into 258,000,000 2580000 times, and whatever you do on the bottom must be done on the top, and since 27 is the percentage, 27 x 2580000 = 69,660,000

making the answer 69,660,000/258,000,000

Answer:

K < - 16

Step-by-step explanation:

[tex]\frac{2k-3}{-5}[/tex] > 7

Multiply both sides by - 5 to clear the fraction, reversing the symbol as a result of multiplying by a negative quantity.

2k - 3 < - 35 (add 3 to both sides )

2k < - 32 ( divide both sides by 2 )

k < - 16

The coding of the statistic is used to make it easier to work with the large sunshine data set

Reason:

The given parameters are;

The sample size, n = 3.

∑x = 947

Sample corrected sum of squares, Sₓₓ = 33,065.37

The mean and standard deviation = Required

Solution:

[tex]Mean, \ \overline x = \dfrac{\sum x_i}{n}[/tex]

The mean of the daily total sunshine is therefore;

[tex]Mean, \ \overline x = \dfrac{947}{30} \approx 31.5 \overline 6[/tex]

[tex]s = \dfrac{x}{10 } - \dfrac{1}{10}[/tex]

[tex]E(s) = \dfrac{31.5 \overline 6}{10 } - \dfrac{1}{10} = 3.05 \overline 6[/tex]

Alternatively

,[tex]The \ mean \ of \ the \ daily \ total \ sunshine, \, s = \dfrac{31.5 \overline 6 - 1}{10 } = 3.05\overline 6[/tex]

The mean of the daily total sunshine, [tex]\overline s[/tex] ≈3.05[tex]\overline 6[/tex]

[tex]Var(s) = \left(\dfrac{1}{10}\right)^2 \times Var \left(x \right)[/tex]

Therefore;

[tex]Var(s) = \left(\dfrac{1}{10}\right)^2 \times 33,065.37 = 330,6537[/tex]

Therefore;

The standard deviation, [tex]s_s[/tex] ≈ 18.184

Step-by-step explanation:

Answer:

56 students

Step-by-step explanation:

Given information:

• 448 students total

• [tex]\frac{3}{8}[/tex] of 448 participate in after-school activities

• [tex]\frac{1}{3}[/tex] of those [tex]\frac{3}{8}[/tex] get home after 7 pm

To find how many students is [tex]\frac{1}{3}[/tex] of those who participate in after-school activities, you first need to find the exact number of how many participate in after school activities:

The amount of students who participate in after-school activities is [tex]\frac{3}{8}[/tex] the total number of students. So, multiply 448 × [tex]\frac{3}{8}[/tex]:

448 × [tex]\frac{3}{8}[/tex]         Multiply.

[tex]\frac{1344}{8}[/tex]               Simplify into a whole number.

1344 ÷ 8       Divide.

168

[tex]\frac{3}{8}[/tex] of the total students is 168 students.

To find the amount of students that do not get home until after 7 pm, multiply 168 by [tex]\frac{1}{3}[/tex]:

168 × [tex]\frac{1}{3}[/tex]          Multiply.

[tex]\frac{168}{3}[/tex]                 Simplify into a whole number.

168 ÷ 3         Divide.

56

The amount of students that participate in after-school activities and get home after 7 pm is 56 students.
