Can anyone give me an answer to this? Help is serverly needed...

Answer:

1. 6.13

2. 0.57

Step-by-step explanation:

1. 7 x 4 = 28

28 / 8 = 3.5

3.5 x 7 = 24.5 / 4 = 6.13

s = 6.13

2. 2 x 3 = 6

6 / 7 = 0.85

0.85 x 2 = 1.71

1.71 / 3 = 0.57

s = 0.57

Sorry if I get most of them wrong

Answer:

A(b) = 145,34 m²

Step-by-step explanation:

Area of the square of side l = 26 m    A(s) = l²      A(s) = (26)²

A(s) = 676 m²

Areaof the circle of radius r = 13  A(c) = π*(r)²  A(c) = π*(13)²

A(c) = 169*π  m²

Then the area outside the circle and inside the square  A(b), is the difference between the area of the square minus the area of the circle, that is:

A(b) = A(s)  -  A(c)  =  676  - 169*π    m²

A(b) = 676  -  530,66  m²

A(b) = 145,34 m²

Calculating volume

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

Answer:

answer for your question is answer number a (384 cm^3)

C - 2,849.6

Just took the test and got it right

Answer:

C - 2,849.6

I got a 100 on the test

Answer:

c = 3477 feet (As rounded to the nearest whole number)

Step-by-step explanation:

We will use the Sin ratio for this problem since the opposite side of the Angle 15 is given and we have to find the triangle's hypotenuse;

Sin(15) = [tex]\frac{900}{c}[/tex]

=> Now isolate the variable c all to itself;

Sin(15) * c = 900

c = [tex]\frac{900}{Sin(15)}[/tex]

c = 3477.33 or 3477 feet

Hope this helps!

Answer:

1 1/3 or 4/3

Step-by-step explanation:

7 10/12 - 6 6/12 = 1 4/12

simplify.

1 1/3

Answer:

4/3 or 1 and 1/3

Step-by-step explanation:

First we need to make the fractions normal. We multiply 7 times 6 to get 42, then add 42 to 5 to get 47/6. Then we multiply 6 times 2 to get 12, then add 1 to that to get 13/2. Then we multiply both the 13 and the 2 by 3 to get 39/6. Then subtract 39 from 47, this gives us 8/6, we can then simplify this to get 4/3 or 1 and 1/3.

Answer:

the first one must be 39.5 and the other 42.5

Step-by-step explanation:

multiply 35 by 6 and subtract 32 x 4 you are left with 82. Divide that by 2 and make the difference 3.

Answer:10

Step-by-step explanation:24-6-8=10

The distance travelled by the ray will be 26 inches. Then the correct option is B.

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

In a science experiment, a student concluded that a ray has to travel a distance from one corner at the top of the rectangular prism to the opposite side where the surface touching the floor is intersected.

If the length, width, and height of the prism are given as 24 inches and 8 inches, 6 inches respectively.

Then the distance travelled by the ray will be

We know the formula

D² = L² + W² + H²

We have

L = 24 in

W = 6 in

H = 8 in

Then the distance will be

D² = 24² + 6² + 8²

D² = 576 + 36 + 64

D² = 676

D = 26 in

Thus, the correct option is B.

Answer:

13

Step-by-step explanation:

There is 13 dots.

Answer:

x = 103

Step-by-step explanation:

In my opinion, because x and 77 are the supplementary angles, so 180-77 = x or x+77=180. The answer should be 103......even though it's not in the options (I'm sorry).

Answer:103 degrees

Step-by-step explanation:

Straight line equals 180 degrees

180 degrees minus 77 degrees = 103 degrees

Answer:

s = 33/8 or 4 1/8

Step-by-step explanation:

find 'k', constant of proportionality first:

8 = 3k

k = 8/3

11 = 8/3s

s = 11/1 ÷ 8/3

s = 11/1 x 3/8

s = 33/8 or 4 1/8

Answer:

flood

Step-by-step explanation:

Answer:

earthquake

Step-by-step explanation:

There is no sign of water on the house materials nor on the pavement so flood and tsunami are out. If a land slide came through, multiply houses would have been seen with this in the back ground which there aren't. So the best possibly choose in my opinion is earthquake.

Answer:

The answer is below

Step-by-step explanation:

a) Cost of hiring the bicycle for 14 days is:

Cost = 65 * 14 days + 44 = 954 riyals

b) The number of days the bicycle is hired is to be the same as the number of days the bicycle is to be hired. Let us assume that the bicycle and helmet is to be hired for x days, hence:

Cost of bicycle = 65 * x + 14 = 65x + 44

Cost of helmet = 12.5 * x = 12.5x

Total cost = 65x + 44 + 12.5x = 77.5x + 44

Since 750 riyals is available, hence:

750 = 77.5x + 44

77.5x = 706

x = 9.11

Therefore the maximum number of days is 11. The total cost for 11 days is:

Total cost = 77.5(9) + 44 = 741.5 riyals

Money not spent = 750 riyals - 741.5 riyals = 8.5 riyals

Answer:

A. The area is [tex]78.54m^2[/tex]

B. She needs to cover 1661.9 square feet of tiles for the base of the swimming pool

Step-by-step explanation:

Question A:

Let us assume that the leash is pegged to the ground using a stake. as a result, the dog can move around the stake. The path that the motion of the dog would trace is a circle, and the radius of the circle will be the length of the leash.

Since we know this, we can easily find the area of the circle using [tex]\pi r^2[/tex]

Area of the circle = [tex]\pi \times 5 \times 5 = 78.54m^2[/tex]

Question B

Dulce wants to cover the whole surface area of the floor of the circular swimming pool with tiles.

We already know that the swimming pool is circular, hence, the surface area of the base of the swimming pool will be the same as the area of a circle, with the same radius.

The area of the circle can be calculated using [tex]\pi r^2[/tex]

Area of circle = [tex]\pi \times 23 \times 23 = 1661.9ft^2[/tex]

Answer:

x =4, x = -6

Step-by-step explanation:

1. Square root the whole equation on both sides

2. You get x+1 = ±5 as the answer.

3. Simplify that to get x = 4 and x = -6.

4. This equation is a quadratic equation, so you should get 2 answers.

Answer:

x=6,−4

Step-by-step explanation:

1.Take the square root of each side of the equation to set up the solution for x

2.Remove the perfect root factor x−1 under the radical to solve for x.

3. Simplify the right side of the equation.

4. The complete solution is the result of both the positive and negative portions of the solution.
