Hector's family traveled 7 10 of the distance to his grandmother's house on Saturday. They traveled 2 3 of the remaining distance on Sunday. What fraction of the total distance to his grandmother's house was traveled on Sunday?

Answer:

[tex]y = 100 * (0.75)^{30[/tex]

Step-by-step explanation:

Given

[tex]a =100[/tex] --- Initial Amount

[tex]r= 25\%[/tex] every 10 years

Required

The remaining amount after 300 years

To do this, we make use of:

[tex]y = a(1 - r)^T[/tex]

Where

r = decay rate

T = the period of decay

In 300 years, there are 30 periods of 10 years.

i.e.

[tex]T = \frac{300}{10}[/tex]

[tex]T = 30[/tex]

[tex]y = a(1 - r)^T[/tex]

[tex]y = 100 * (1 - 25\%)^{30[/tex]

[tex]y = 100 * (1 - 0.25)^{30[/tex]

[tex]y = 100 * (0.75)^{30[/tex]

( Lol I just had this same problem on my homework)

Answer:

40 cm.

Step-by-step explanation:

If 2 cups is 16 cm, and 4 cups are 20cm. You can multiply 4 by 2 to get 8. (20 x 2 = 40cm)

(16 divided by 2 = 8). ( 8 = the total length of each cup)

So...

( 8 cups are = to 40 cm)

Hope this helps

Explanation:

The base faces are the two triangles that are parallel to one another. We'll be ignoring those faces when computing the lateral surface area.

Instead, we focus on the three rectangles that form the sides. We can think standing the prism on one of the triangular faces, so that one triangle is the floor and the other triangle is the ceiling. The rectangular pieces are the walls of this room.

The three areas then combine to 128+96+96 = 320 square cm which is the lateral surface area.

------------------

As a different approach, we can use this formula

LSA = p*h

where LSA is the lateral surface area, p is the perimeter of the base polygon, h is the height of the prism.

The base triangle has sides of 8, 6 and 6. So the perimeter is p = 8+6+6 = 20 cm. The height is h = 16 cm. The LSA is therefore,

LSA = p*h = 20*16 = 320 square cm.

Answer:

The length of fencing Matias needs is 51 meters

Step-by-step explanation:

The given parameters are;

The dimensions of Matias' backyard from which half is to be turned into a chicken pen = 24 m by 45 m

The orientation of the fence that is will be made for the chicken pen = Stretch diagonally across the backyard (from a corner to the opposite corner)

From the question, Matias' backyard is rectangular in shape

Therefore, by Pythagoras theorem;

The length of the diagonal fence = √((24 m)² + (45 m)²) = 51 m

Matias needs 51 meters of fencing for the diagonal fence.

Step-by-step explanation:

if she can drive 252 miles with 12 gallons, you must divide 252 and 12 to figure out how many miles she can get per gallon. Once you find that answer, you multiply that by 16 gallons.

Step-by-step explanation:

Answer:

52

Step-by-step explanation:

the angles on any triangle together equal 180 degrees. add up the two angles you know (36+92) and you get 128 degrees. then subtract that (128) from 180 and you get 52. 52 degrees is the missing angle.

Answer:

78 = d

Step-by-step explanation:

13 = d/6

Multiply each side by 6

13*6 = d/6*6

78 = d

Step-by-step explanation:

Answer:

78

Step-by-step explanation:

probability of getting a 5 which is 78.

Another way to look at this is that if we know the probability of the result being 5, then the probability of it not being 5 is just one minus that probability. We know that 5 is just one out of the 8 possibilities, so

P5=18

So the probability of not 5 is

Pnot5=1−P5=1−18=78

Answer:

AD = 1.96

BD = 6.72

CD = 23.04

Step-by-step explanation:

7/25 = AD/7

25AD = 49

AD = 1.96

24/25 = BD/7

25BD = 168

BD = 6.72

CD = 25 - 1.96 = 23.04

Answer:

6x + 7 - 2x + 2 + 3x

= 6x -2x + 3x +7 + 2

9x - 2x + 9

7x + 9

7x = -9

x = -9/7

Answer:

t=5.25x

Step-by-step explanation:

since X equals the number of egg cartons sold then we would have to multiply that by how much one egg carton costs (5.25$ each)

so if they sold 3 egg cartons the equation would be t=5.25*3.

(putting a variable next to a number means your multiplying it)

I hope I explained that clearly enough :P

Answer:

You would have to look at the explanation since there are multiple

Step-by-step explanation:

-7x + 1 would have to be greater than or equal to 15.

-7(2) + 1 = 15 so you would mark a filled in dot at 2 and point an arrow going to the right.

6x + 3 must be greater than or equal to -21.

6(-4) + 3 would equal -21 so you would mark a filled in dot at negative 4 with an arrow going to the right.

Step-by-step explanation:

Answer:

where are the answer choices

Step-by-step explanation:

Answer:

2x + 3 = 7x + 4

3 + 2x = 7x + 4

3 + 2x = 4 + 7x

3 + 2x = 4 + 7x

3 + 2x + -7x = 4 + 7x + -7x

2x + -7x = -5x

3 + -5x = 4 + 7x + -7x

7x + -7x = 0

3 + -5x = 4 + 0

3 + -5x = 4

3 + -3 + -5x = 4 + -3

 3 + -3 = 0

0 + -5x = 4 + -3

-5x = 4 + -3

4 + -3 = 1

-5x = 1

 x = -0.2
