Asia can rake her yard's leaves in 2 hours. It takes Isaac 6 hours to rake the yard's
leaves by himself. How long would it take if Asia and isoac work together?
Is will be 1 hour and 30 minutes

For the first one we divide every element by sqrt3

we get

q+2/sqrt3 =sqrt5/sqrt3

q=(sqrt5-2)/sqrt3

q=sqrt3*sqrt5-2*sqrt3/3

q=sqrt15-2sqrt3/3

which is the third option

For the second one

sqrt(2y-5) +4=8

first we move the 4 to the right

sqrt(2y-5)=4

we remove the square root by bringing to the power of two

2y-5=16

2y=21

y=21/2

y=10 1/2

third option

Answer:

x=2

Step-by-step explanation:

Answer:

x = 2

y = -1

Step-by-step explanation:

8x + 2y = 14

2x + y = 3

In order to find the number x represents, you have to make the number of y for both equations the same. So:

8x + 2y = 14

(×2) 4x + 2y = 6 (×2)

Then, you can cancel the y off both equations, which will leave:

8x = 14

4x = 6

To find 4x, you have to find the difference between both equations, so you have to:

14 - 6 = 8

Now that the actual number 4x represents is 8, so:

4x = 8

(÷4) x = 2 (÷4)

Now to find y, substitute the letter x with 2:

2x + y = 3

2 (2) + y = 3

4 + y = 3

4 - 3 = -y

1 = -y

(× -) -1 = y (× -)

Answer: x = 2

              y = -1

Hope this helps!  :)

Answer:

5b - 3

Step-by-step explanation:

5b-3 is the algebraic expression for "3 less than the product of 5 and b"

Expression is a combination of variables, numbers and Operators.

The given sentence is

"3 less than the product of 5 and b"

Let us write the sentence in algebraic form.

We know that product of 5 and b means multiplication of 5 and b that means five times of b.

3 less than means subtracting 3 from another number.

So 3 less than the product of 5 and b is 5b-3.

Hence 5b-3 is the algebraic expression for "3 less than the product of 5 and b"

The volume, in cubic in, of a cylinder with a height of 15 in and a base radius of 5 in is 1177.5 cu.in.

A fixed planar closed curve intersects a surface traced by a straight line traveling parallel to a fixed straight line , is called as a Cylinder.

It is given that the height of the cylinder = 15 inch

Base radius = 5 inch.

The volume of the cylinder is given by

V = π r²h

V = π 5² * 15

V = 3.14 *25 *15

V = 1177.5 cu.in

Answer:

∠GEF = 25

Step-by-step explanation:

Here, we want to find the value of the marked angle

Please check the attachment for the diagrammatic representation of the triangle

Mathematically, the sum of opposite interior angles equals the exterior angle

We can have this sum as follows;

∠EFG + ∠GEF = ∠FGH

Thus;

2x + 1 + x + 19 = 6x + 2

3x + 20 = 6x + 2

6x-3x = 20-2

3x = 18

x = 18/3

x = 6

Now , substitute x into the ∠GEF

That will be;

6 + 19 = 25

Step-by-step explanation:

I suggest to make a table

x        y

( )      ( )

( )      ( )

and on each section put the points on the correct input and output

once you do that you want to see how much you need to add or subtract to get to the other input or output

For example

if i have ( 5, 10) and ( -5, -10)

I would make a table that looks like this with each of the inputs and outputs.....

x       y

5      10

-5      -10

From 10 to -10 you need to subtract 20

from 8 to -8 you need to subtract 10

so y/x

-20/-10

2 negative numbers make a positive so...

your slope will be 2

Answer:

b = 2.25

Step-by-step explanation:

Here, we want to get the value of b

from the question;

s(x) = ab^n

Firstly;

15 = a•b^5

Secondly

170 = a•b^8

Divide second by first

170/15 = ab^8/ab^5

11.33 = b^3

b is the cube root of 11.33

b = 2.25

Answer:

sin = p/h.

cos=b/h

tan =p/b

h^2=p^2+b^2

here

h=5

p= 3

b=4

Answer:

sin(A)=3/5

cos(A)=4/5

tan(A)=3/4

Step-by-step explanation:

length of the other side is 5 using pythagorean theorem

sin= opposite/hypotenuse

cos= adjacent/hypotenuse

tan= opposite/adjacent

opposite angle A- 3

adjacent angle A- 4

Answer:

The height of water in the container is 5 cm

Step-by-step explanation:

Here, we want to calculate the height of the water in the container

Mathematically, the volume is :

50 * 30 * h = 1500h cm^3

Also, 7.5 L = 7500 cm^3 = 7.5 L

Let the height be h

1500h = 7500

h = 7500/1500

h = 5 cm

Answer: $75.0

Step-by-step explanation:

Based on the above figures given in the question, the length of the rectangular garden will be 9feet and the width will be 6feet

Length = 9feet.

Width = 6feet

Perimeter = 2 (length + breadth).

= 2(9feet + 6feet)

= 2 (15feet)

= 30 feet

Since fencing is in sale for $2.50 per foot, the amount that she will spend to put a fence around her garden will be:

= $2.50 × 30

= $75.0

The line segment AC (side a) is the longest side of triangle ABC.

To determine which side of triangle ABC is the longest, we can use the concept that the side opposite the largest angle in a triangle is the longest side. In this case, angle B is the largest angle with a measure of 75 degrees.

Now, we can identify the side opposite angle B, which is line segment AC. Therefore, line segment AC is the longest side of triangle ABC.

To calculate it more formally, we can use the law of sines. The law of sines states that in any triangle, the ratio of the length of a side to the sine of its opposite angle is the same for all three sides. The formula is:

a/sin(A) = b/sin(B) = c/sin(C)

Where:

a, b, c are the side lengths of the triangle.

A, B, C are the angles opposite to sides a, b, c, respectively.

Let's calculate the length of side AC (a) using the law of sines:

a/sin(A) = b/sin(B) = c/sin(C)

a/sin(45°) = b/sin(75°) = c/sin(60°)

a/√(2) = b/sin(75°) = c/sin(60°)

Now, we know that b < a and c < a because angle B is the largest angle. So, to find the value of a, we need to solve for it.

a = √(2) * b and a = (√(3)/2) * c

Now, we have three sides in terms of one variable (a, b, and c), and we know that a > b and a > c. Therefore, line segment AC (side a) is the longest side of triangle ABC.
