A school has a 20:2 student - teacher ratio graph a line representing this scenario part b what is the unit rate

9966 [12]

The unit rate is 10:1 because unit rates are out of 1
You would find that by dividing 20 and 2 by the same number to get to one for this specific problem. 20 divided by two is ten and two divided by two is one. So that is your answer for part b. I can’t draw a graph however so sorry

Each week, Aubrey earns $50 for every shift he works at the diner and $17 for every dog-walking job. He uses the expression 50x

andrew11 [14]

Answer:

A. coefficients: 70, 12; variables: x, y.

B. 2 terms: 70x, 12y; separated by an addition symbol

C. 70x

Step-by-step explanation:

We will answer the questions in the context of this problem. In other problems, the meaning of "coefficient", "variable", and "term" may be different.

__

A. The coefficients are the numbers; the variables are the letters. Then the coefficients are 70 and 12; the variables are x and y.

__

B. Each product is a term. Terms are separated by the + sign. There are two terms in this expression, one on either side of the + sign. When an expression is written with no parentheses, the terms are separated by + or - signs. (Often, we think of the minus sign as being part of the coefficient of the term. Then we can say terms are separated by + signs. 10x + (-32y), for example.)

__

C. When you match the coefficients to the numbers in the problem statement, you see that the number matching the earnings at the diner is $70 per shift. If we assume that x represents the number of shifts worked at the diner, then the term 70x will represent the total earned from the diner. It is the product of the earnings per shift and the number of shifts.

Multiply and simplify the following products. V stands for radical.

Reptile [31]

Answer:

(1) 9

(2) $\sqrt{6}$

(3) 6( $\sqrt{6}$ )

Step-by-step explanation:

From the question,

(1) ( $\sqrt{9}$ )²

Applyin the law of multiplication of surds

( $\sqrt{9}$ )² = (

(2) ( $\sqrt{2}$ )× ( $\sqrt{3}$ ) =

Also applying the the law of multiplication of surd

( $\sqrt{2\\}$ )×( $\sqrt{3}$ ) = ( $\sqrt{6}$ ) ( This is an irational answer)

∴ ( $\sqrt{2}$ )×( $\sqrt{3}$ ) = $\sqrt{6}$

(3) 2( $\sqrt{2}$ )×3( $\sqrt{3}$ )

Also applying the law of multiplication of surds i.e Multiply surds to surds and whole number to whole number

= 2×3×( $\sqrt{2}$ )×( $\sqrt{3}$ )

6×( $\sqrt{6}$ ) = 6(

Whats nine tenths mines three fiths

11Alexandr11 [23.1K]

To subtract fractions, we need a common denominator, which would be 10. To do this, multiply 3/5 by 2

3 * 2 = 6

5 * 2 = 10

Now subtract

$\dfrac{9}{10}-\dffrac{6}{10}=\dfrac{3}{10}$
