Answer:

3/8

Step-by-step explanation:

After spending 3/8 of her money on a bag, she has 5/8 of the original amount of money left. As she gave 2/5 of the remaining amount of money to her sister, she gave 1/4 of the original amount of money to her sister (5/8 × 2/5 = 1/4). Therefore, there's only 3/8 (1 - 3/8 - 1/4 = 3/8) of the original amount of money left in her bag.

Answer:

132.67 ft^2

Step-by-step explanation:

this sector's area equals the area of the whole circle divided by four;

the whole are = r x r x 3.14 = 13 x 13 x 3.14 = 530.66

the sector's area = 530.66/4 = 132.67 ft^2

Answer:

6.5

Step-by-step explanation:

im doing this for points ok

The solution is, it take 6.5 hours for the container to empty.

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,,

given that,

A container holds 54.6 gallons of liquid.

The container leaks 8.4 gallons per hour.

i.e. we get,

8.4 gallons leak in 1 hour

so, 54.6 gallons will leak in = 54.6/ 8.4 hours

now, we get,

54.6/ 8.4

=6.5

Hence, The solution is, it take 6.5 hours for the container to empty.

Answer:

  3.77

Step-by-step explanation:

For daily compounding, the balance is ...

  A = P(1 +r/365)^n . . . . principal P invested at annual rate r for n days

  A = 1000(1 +0.055/365)^25 ≈ 1003.77

Of this amount, 1000 is the original principal. The difference is the interest.

The interest earned is 3.77.

Answer:f is the answer

Step-by-step explanation:

Answer:

The answer is answer D, x=42.

Step-by-step explanation:

To isolate the variable, you need to divide both sides of the equation by three, using the division property of equality. 126/3=42 , and 3x/3=x , this gives you 42=x, or x=42, meaning the answer is D.

Answer:

x = - 5, y = - 1

Step-by-step explanation:

Given the 2 equations

- 5x + 3y = 22 → (1)

- 6x + 7y = 23 → (2)

Multiplying (1) by - 6 and (2) by 5 , then adding will eliminate the x- term

30x - 18y = - 132 → (3)

- 30x + 35y = 115 → (4)

Add (3) and (4) term by term to eliminate x

0 + 17y = - 17

17y = - 17 ( divide both sides by 17 )

y = - 1

Substitute y = - 1 into either of the 2 equations and solve for x

Substituting into (1)

- 5x + 3(- 1) = 22

- 5x - 3 = 22 ( add 3 to both sides )

- 5x = 25 ( divide both sides by - 5 )

x = - 5

Answer:

560/9 or around 63 cubes

Step-by-step explanation:

2 2/3 -> 8/3

3 1/3 -> 10/3

2 1/3-> 7/3

7/3 x 8/3= 56/9

56/9 x 10/3 = 560/27

560/27 divided by 1/3

= 560/9

Answer:

See answers below

Step-by-step explanation:

Perimeter of a square = 4L

L sis the side length of the square

L = 5x^4y^2

perimeter = 4(5x^4y^2)

perimeter = 20x^4y^2

2) Length = 6x-10

Width = 4x+3

Area of rectangle = Length * Width

Area of rectangle = (6x-10)(4x+3)

Area of rectangle = 24x^2+18x-40x-30

Area of rectangle= 24x^2-22x-30

perimeter = 2(L+W)

perimeter 2(6x-10+4x+3)

perimeter = 2(10x-7)

perimeter  = 20x-14

Hence the perimeter of the rectangle is 20x-14

The line for the graph x=1 is the line of reflection that reflects triangle ABC onto triangle A'B'C'.

You have to find the middle points between each pair of identical points and then join them.

The solution is, x = 1 will be the line of reflection.

In mathematics, a reflection (also spelled reflexion) is a mapping from a Euclidean space to itself that is an isometry with a hyper plane as a set of fixed.

here, we have,

from the given information , we get,

Coordinates of the vertex A → (-4, -6)

Coordinates of the vertex A' → (6, 6)

Since, y-coordinates are same opposite in notation,

Therefore, by the rule of reflection, line of reflection will be a line parallel to y-axis.

And points A and A' will be equidistant from the line of reflection.

Midpoint between A and A' = (x1+x2/2) , (y1+y2/2)

                                             = (-4+6 / 2 , -6+6 /2)

                                             = (1, 0)

Therefore, x = 1 will be the line of reflection.

Answer:

we can conclude that there is significant evidence that there is convincing evidence that the average attention span for teenage boys is more than 5 minutes

Step-by-step explanation:

H0 : μ ≤ 5

H1 : μ > 5

Sample mean, xbar = 6.2

Sample Standard deviation, s = 2.1

Sample size, n = 80

The test statistic :

(xbar - μ) ÷ (s/sqrt(n))

(6.2 - 5) ÷ (2.1 / sqrt(80))

1.2 ÷ 0.2347871

Test statistic = 5.1110133

Testing with α = 0.05

Using Pvalue from a test score calculator :

Pvalue = < 0.00001

0.00001 < 0.05

Since,

Pvalue < α ; We reject H0

Hence, we can conclude that there is significant evidence that there is convincing evidence that the average attention span for teenage boys is more than 5 minutes.

Answer:

[tex]AC = \frac{20}{3}[/tex]

Step-by-step explanation:

Given

[tex]AB = 4[/tex]

[tex]XY = 3[/tex]

[tex]XZ = 5[/tex]

Required

Find AC

ABC XYZ

To solve AC, we make use of the following equivalent ratios.

[tex]AB : AC = XY : XZ[/tex]

This gives:

[tex]4 : AC = 3 : 5[/tex]

Express as fraction

[tex]\frac{4 }{ AC }= \frac{3 }{ 5}[/tex]

Cross multiply

[tex]3 * AC = 4 * 5[/tex]

[tex]3 * AC = 20[/tex]

Solve for AC

[tex]AC = \frac{20}{3}[/tex]

Answer:

  A)  3x +10y = 36

Step-by-step explanation:

The graph tells us the x-intercept is 12. The x-intercept is the value of x when y = 0. For some equation coefficients ax+by=36, the x-intercept is ...

  x-intercept = 36/a

Then the coefficient 'a' is ...

  a = 36/(x-intercept) = 36/12 = 3

Only one answer choice has an x-coefficient of 3 -- the correct one.

  3x +10y = 36

Answer:

x > 16

Step-by-step explanation:

3/4x > 12

3x > 48

x > 16

hope this helps

Step-by-step explanation:

for the first one multiply the equation by 5

5(-10)=5(1/5)a

-50=a

2.  3(n-8)=-12

divide the equation by 3

(3(n-8))/3=-12/3

(n-8)=-4

add 8 to both sides

n-8+8=-4+8

n=4

3.   8+4x=-16

subtract the whole equation by 8

-8+4x=-16-8

4x=-24

divide the equation by 4

4x/4=-24/4

x=-6

4. 4 chicken sandwiches at $2.50 each, to find the value of all the values for all 4 sandwiches is 4(2.50)=10

and since there is only one hamburger you just need to find the value for the one burger which is x.

4(2.50)+1(x)=14.30

10+x=14.30

subtract the equation by 10

10-10+x=14.30-10

x=4.30

Hope this helps :)
