Answer:

Three fifths

Step-by-step explanation:

Since 10 was divided by 2 to get 5,

you just do the same to the top half of the fraction.

So when you divide 6 by 2, you get 3.

So it is equal to 3/5, or three fifths.

And 3/5 is equivalent to 6/10

statement: segment HA is parallel to seg HD and seg HD is parallel to seg AN.

Reason: given

statement: angle 1 is congurent to angle 3.

reason: alternate interior angles are congruent.

statement: angles 2 and 4 are congruent

reason: alternate interior angles are congruent.

statement: Seg DA is congruent to seg DA

reason: reflexive property

statement: angle AHD is congruent to angle AND

reason: since angles 1 and 3 are congruent, and 2 and 4 are congruent, and HDA is a triangle, same with AND, the last angle must be congruent.

statement: seg HD is congruent to seg NA and HA is cong to ND.

reason: ASA angle side angle theorem states that if 2 angles and a side is congruent to the corresponding parts of another triangle, then it is congruent.

For every 1 litre of water used 150ml of sucrose and 600ml of saline solution is used

Answers

Question:

For every 1 litre of water used to make a medicine, 600 ml of sucrose and 150ml of saline solution are used.

Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

Answer:

[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]

Step-by-step explanation:

Given

[tex]Water = 1L[/tex]

[tex]Sucrose = 150mL[/tex]

[tex]Saline= 600mL[/tex]

Required

Express as a ratio to the simplest form

First convert the volume of water to mL

[tex]Water = 1L[/tex]

[tex]Water = 1 * 1000mL[/tex]

[tex]Water = 1000mL[/tex]

Express as ratio:

[tex]Water : Sucrose : Saline = 1000mL : 150mL : 600mL[/tex]

[tex]Water : Sucrose : Saline = 1000 : 150 : 600[/tex]

Divide through by 10

[tex]Water : Sucrose : Saline = 100 : 15 : 60[/tex]

Divide through by 5

[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]

The ratio can not be further simplified

In the expression 3x - 4y + z, what is the
coefficient of z?

Answers

Answer:

Step-by-step explanation:

The coefficient is the number in front of a variable. There is a hidden coefficient of 1 in front of z. The reason it is not shown is because any number multiplied by 1 is just that number so showing the 1 is redundant.

The coefficient of z in the expression 3x- 4y +z is 1.

What is expression?

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

3x - 4y + z

As, we know a coefficient is a number that is multiplied by a variable.

So, the coefficient of x is 3, coefficient of y is 4 and coefficient of z is 1.

Step-by-step explanation:

Two cars leave towns 760 kilometers apart at the same time and travel toward each other. One car's rate is 12 kilometers per hour less than the other's. If they meet in 4 hours, what is the rate of the slower car

Answers

Answer:

89 km/hr

Step-by-step explanation:

Distance = Rate(speed) × Time

D = R × T

T = 4 hours

One car's rate is 12 kilometers per hour less than the other's.

Hence:

First's car's rate = r × 4 = 4r

Second car's distance = (r + 12) × 4 = 4r + 48

4r + 4r + 48 = 760

8r + 48 = 760

8r = 760 - 48

8r = 712

r = 712/8

r = 89 km/hr

The rate of the slower car is 89 km/hr

For the polynomial state a common factor of all monomials and factor it out. 3/2*x^2yz-9/8*xyz+15/4*xy

Answers

Answer:

3/2x²yz – 9/8xyz + 15/4xy = 3/2xy[xz – 3/4z + 5/2)

Step-by-step explanation:

Given 3/2x²yz – 9/8xyz + 15/4xy. Let's look for a common factor.

3/2x²yz = 3/2 * x * y * z

9/8xyz = 3/2 * 3/4 * x * y * z

15/4 = 3/2 * 5/2 * x * y

Looking at the above; 3/2, x and y are common to all terms. Therefore the factor is:

3/2xy. Now let's factor it from each term

3/2x²yz = 3/2xy(xz)

9/8xyz = 3/2xy(3/4z)

15/4xy = 3/2xy(5/2), therefore we have:

3/2x²yz – 9/8xyz + 15/4xy = 3/2xy[xz – 3/4z + 5/2).

Find the value of x?

Answers

Answer:

x = 14

Step-by-step explanation:

Since it's a parallelogram that means x+3= 17.

Subtract 17 by 3 to get x alone that will give you x = 14

Answer:

x = 14

Step-by-step explanation:

This quadrilateral is a parallelogram. Due to this, opposite sides are congruent. One side is 17, that means the opposite side is 17. We can write this as the equation

x + 3 = 17.

If we subtract 3 from both sides, we isolate the variable x.

x = 14.

Therefore, x = 14

You have budgeted $4,800 for a company to complete guest satisfaction surveys for you. They charge $1,800 + $6 per respondent. How many respondents will you be able receive for the money paid?

Answers

Answer:

Step-by-step explanation:

There are 500 respondents will you be able receive for the money paid.

What is mean by expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The budgeted for a company to complete guest satisfaction surveys for you is, $4,800.

And, They charge $1,800 + $6 per respondent.

Now,

Let Number of respondents will you be able receive for the money paid is, x

Hence, We can formulate;

⇒ $1800 + $6x = $4800

⇒ 1800 + 6x = 4800

⇒ 6x = 4800 - 1800

⇒ 6x = 3000

⇒ x = 500

Thus, There are 500 respondents will you be able receive for the money paid.
