Can u pls help me with this question

Answer:

B - 1/9

Step-by-step explanation:

I don't really know how to explain how I got it because I'm only in middle school in pre-algebra, but I did teach this to myself online haha, so here we go. Daneille rolled the dice 90 times, it only landed on 6 10 times. That is 10/90 which, simplified, is 1/9.

Answer:

Simplified fraction: 5/2   Decimal: 2.5

Step-by-step explanation:

20/8 simplified is 5/2 which can also be said as 2 1/2 or 2.5.

(hope this helps)

Answer:

X is parent 1

z is parent 2

y is parent 3

Answer:

Please check the explanation.

Step-by-step explanation:

Let suppose we have a point P(x, y) if we rotate our point 90 degrees counterclockwise about the origin, the new coordinates of the image of the point P can be obtained by switching 'x' and 'y' and making 'y' negative.

In other words,

P(x, y) → P'(-y, x)

From the given triangle ΔRST,

The coordinates of the point S is:

According to the rule, if we have a point S(10, 1), after rotations of 90 degrees counterclockwise about the origin, the new coordinates of the image of the point S(10, 1) will be:

S(10, 1) → S'(-1, 10)

Here,

S'(-1, 10)  is the image of the original point or pre-image point S(10, 1).

Therefore, the y-coordinate of the point S' is: 10

Answer:

The length of the box is (x + 1)

The height of the box is (x + 1)

Step-by-step explanation:

The given function representing the volume of the box is presented as follows;

V = x³ + 6·x² + 9·x + 4

The function representing the width of the box, W = x + 4

Therefore, we have;

(x³ + 6·x² + 9·x + 4)/(x + 4) = x² + 2·x + 1

x³ + 4·x²

    [tex]{}[/tex]  2·x² + 9·x + 4

    [tex]{}[/tex]  2·x² + 8·x

    [tex]{}[/tex]               x + 4

Therefore, we have;

(x³ + 6·x² + 9·x + 4) = (x + 4) × (x² + 2·x + 1) = (x + 4) × (x + 1) × (x + 1)

(x³ + 6·x² + 9·x + 4) = (x + 4) × (x + 1) × (x + 1)

The width of the box = (x + 4)

The length of the box = (x + 1)

The height of the box = (x + 1).

Answer:

123

Step-by-step explanation:

(6^2+5)*3= 41*3= 123

Answer:

Step-by-step explanation:

take away the parenthesis

9 - 3 = 6

6² + 5 ÷ ⅓

take away the exponents

6 * 6 = 36

36 + 5 ÷ ⅓

36 + 5 = 41

41 ÷ ⅓

( 41 ÷ 1 ) ÷ 3

41 ÷ 3

13.66666666666667

Round it up, and u get

13.7 or 14 depends on how much u want to round it up to.

Step-by-step explanation:

Answer:

b

Step-by-step explanation:

Answer:

12.68

Step-by-step explanation:

With reference angle 45°

perpendicular (p) = 9

hypotenuse (h) = c

Now

sin 45 ° = p/ h

0.71 = 9 / c

c = 9 / 0.71

c = 12.68

Hope it will help :)

Answer:

The solution to the system of equations will be: (-6, 24)

Step-by-step explanation:

Given the system of equations

y = -3x+6

x = -6

substituting x = -6 in the equation y = -3x+6

y = -3x+6

y = -3(-6) + 6

y = 18+6

y = 24

Therefore, the solution to the system of equations will be: (-6, 24)

Note: it seems you have not mentioned the correct option in the answer choice as the correct choice is (-6, 24).

Answer:

  1) see below

  2) 2.5 inches per day

  3) the seed was planted below ground level

  4) h = 2.5d -3

Step-by-step explanation:

1) We note that the seedling grew 12-7 = 5 inches in the 2 days between day 4 and day 6. This lets us fill in the numbers for even days by adding or subtracting 5 inches:

  day 8 will be 5 inches more than day 6, 17 inches.

  day 2 will be 5 inches less than day 4, 2 inches.

  day 0 will be 5 inches less than that, -3 inches.

The value for day 3 will be halfway between day 2 and day 4, so will be (2+7)/2 = 4.5 inches.

See the attachment for the complete table.

__

2) In one day, the plant grows in/day = 5/2 = 2.5 inches.

__

3) If the plant grows at the steady rate of 5 inches in 2 days, it must have been planted 3 inches below ground on day 0.

__

4) In question 2, we found the rate per day (slope) to be 2.5. In question 3, we found the "y-intercept" to be -3. Then the slope-intercept equation with independent variable d and dependent variable h is ...

  h = 2.5d -3

Step-by-step explanation:

as we know

law of cosine

[tex]c = \sqrt{ {a}^{2} + {b}^{2} - 2ab. \cos(c) } [/tex]

[tex]c = \sqrt{ {14}^{2} + {18}^{2} - 2.14.18 - \cos( {35}^{o} ) } [/tex]

[tex]c = 10.35[/tex]

using the law of cosine

[tex]cos(a) = \frac{ {b}^{2} + {c}^{2} - {a}^{2} }{2bc} [/tex]

[tex] \cos(a) = \frac{ {18}^{2} + {10.35 }^{2} - {14}^{2} }{2.18.(10.35)} [/tex]

[tex]a = {50.87}^{o} [/tex]

b=87.13°

Answer:

uhm x > 5. I hope that helps pls lmk

m = 4/5 for the perpendicular line

m = -5/4 for the parallel line

y = -5/4x + 3

for the line above, m = -5/4

The line parallel to this line would have exactly the same slope m =  -5/4

The line perpendicular to this line would have a  slope equal the inverse with the opposite sign  

m = -5/4

So m = (1/(5/4)) is the slope of the m for the perpendicular line

m = 4/5

Answer:

The height of the triangle is: h = 6.4 cm

Step-by-step explanation:

Given

Area of the triangle A = 40 cm²

The Base of the triangle b = 12.5 cm

To determine

height of triangle h = ?

We know that the area A of a triangle is:

A = 1/2 bh

where

so

A = 1/2 bh

substituting A = 40 and b = 12.5

40 = 1/2 (12.5) h

40 × 2 = 12.5 h

12.5 h = 80

divide both sides by 12.5

12.5h/12.5 = 80/12.5

h = 6.4 cm

Thus, the height of the triangle is: h = 6.4 cm

Answer:  It takes 3 seconds to do one of both i think

Step-by-step explanation:

19 and 6 was 75 and 18 and 6 was 72 which means 1 push up is 3 seconds multiply 3 by 18 that is 54 then subtract 72 by 54 which gives you 18 then divide 18 by 6 which is 3

Answer:

No, X=7

Step-by-step explanation:

Answer:

Yes, both equations will always work, but yes, at times it is more logical to use one over the other. for instance:

x-4y=6

x+4y=12

we see here that elimination would best fit:

x+x+4y-4y=6+12

or:

x=2y-3

7x+3y-81=23

substitute (2y-3) for x.

Also, once you have a single placeholder, put it ito quadratic form (ax^2+bx+c=0)

and use the quadratic formula:

x=(-b±sqrt(b^2-4ac))/2a
