Answer:

7/2

Step-by-step explanation:

To get the number of 1/2 cup servings in 7/4 cups of rice you need to divide 7/4 by 1/2

7/4 ÷ 1/2

7/4×2/1----------------------multiplied by the reciprocal

14/4-----------------simplify by dividing both parts by 2

7/2----------------simplest fraction form

1. Howard's CD House sells new CDs for $15 each and used CDs for $6 each. Bre'anna bought 51 CDs and spent a

Yanka [14]

The numbers of new CDs is 30 and the old CDs is 21.

To solve this problem, we have to write a system of equations in which we would know the numbers of each types of CD she bought.

<h3>System of Equations</h3>

This is used to solve a series or complex of word problems in which we can represent in a mathematical statements;

Let n represents numbers of new CDs
Let u represents numbers of old CDs

The equations can be represented as

$n + u = 51 ...equation(i)\\15n + 6u = 576 ... equation(ii)$

Let's take equation (i)

Making n the subject of formula

$n + u = 51\\n = 51 - u...equation(iii)$

we can put equation (iii) into equation (ii)

$15n + 6u =576\\n = 51 - u\\15(51 - u) + 6u = 576\\765-15u + 6u = 576\\collect like terms\\765-576=15u - 6u\\189=9u\\9u/9 = 189/9\\u = 21$

Let's put the value of u into equation (i)

$n + u = 51\\u = 21\\n + 21 = 51\\n = 51 - 21\\n = 30$

From the calculations above, the numbers of new CDs is 30 and the old CDs is 21.

The measure of two supplementary angles, ls and lt, are in the ratio of 7:3. find the value of mls.

ioda

The value of measure of ls is 126 degrees.

It is given in the question that the measure of two supplementary angles, ls and lt, are in the ratio of 7:3.

We have to find the value of measure of ls.

Let the measure of two supplementary angles ls and lt be 7x and 3x respectively.

We know that, the sum of measure of two supplementary angles is 180 degrees.

Hence, according to the data given in the question, we can write,

7x + 3x = 180 degrees

10x = 180

x = 180/10

x = 18 degrees

Hence,

mls = 7x = 7*18 = 126 degrees.

Answer:

$(x-2)^{2} +(y+6)^{2} =49$

Step-by-step explanation:

equation of circle =

$(x-h) ^{2} + ( y-k)^{2} = r^{2}$

( h , k ) = center of origin

$r^{2}$ = radius

origin = ( 2 , -6 )

radius = 7

$(x-2)^2+(y+6)^2=49$
