Given:

Ratio is [tex]2\dfrac{1}{4}:6\dfrac{3}{4}[/tex]

To find:

Convert this ratio to a unit rate.

Solution:

We have,

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{2\times 4+1}{4}:\dfrac{6\times 4+3}{4}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{8+1}{4}:\dfrac{24+3}{4}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{9}{4}:\dfrac{27}{4}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{\dfrac{9}{4}}{\dfrac{27}{4}}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{9}{27}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{1}{3}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=0.333...[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}\approx 0.33[/tex]

Therefore, the unit rate is about 0.33.

Answer:

(a) ER = 29.5

(b) SR = 29.5

(c) DR = 18.6

Step-by-step explanation:

(a) PE=ER, ES is a perpendicular bisector of PR.

(b) Tryangle SER is an isosceles triangle, therefor SR is = to ER.

(c) QD = DR, DS is a perpendicular bisector of QR.

Bisectors cut and angle or line in half.

Perpandicular means makes a 90 degree angle.

Step-by-step explanation:

Width = 4x + 3

Length = 2(4x + 3) = 8x + 6

Area = Width x Length

Area = (4x + 3)(8x + 6)

Area = 32x² + 24x + 24x + 18

Area = 32x² + 48x + 18

Answer:

y=4/3x-2

Step-by-step explanation:

We know the base equation is mx+b and the y-intercept is at -2 so we can determine that as the b value. The m value is 4/3 because if you look at where the line meets the next point is over 3 and up 4 indicating that the m value is 4/3. Hope this helps!

The equation of the line is y = 4/3x -2.

The y-intercept is -2 because the line crosses the y-axis at (0,-2).

The slope is 4/3x because the rise over run of the line is 4/3.

Answer:

y > x² – 2x – 3

y > 3x + 4

Step-by--step explanation:

Answer:

She has  n= 4 side dishes.

Total side dishes ordered = 5n = 20

Step-by-step explanation:

The total cost is given by

TC= 10 . 50 + 1 . 50 ( n − 1 )

She orders same 5 lunches for $ 75

$ 75= 5{ 10 . 50 + 1 . 50 ( n − 1 ) }

Or

Cost of 1 lunch would be $ 15

$ 75/5 = { 10 . 50 + 1 . 50 ( n − 1 ) }

or

$ 15 = 10 . 50 + 1 . 50 ( n − 1 )

$ 15-$  10 . 50 = 1 . 50 ( n − 1 )  

$ 4.5/ 1.5= n-1

$ 3= n-1

3+1= n

n= 4

She has  n= 4 side dishes.

Total side dishes ordered = 5n = 20

She spent

$ 1.50 ( 4-1) = $ 4.5 each day or $22.5 on side dishes for 5 days.

The time practiced in the 12 days is an illustration of proportions

The given parameters are:

Days = 12

Proportion = 3/4

So, the number of hours is:

Hours = Days * Proportion

This gives

Hours = 12 *3/4

Hours = 9

Hence, she practices a total of 9 hours in the 12 days

There are 60 minutes in an hour.

So, we have:

Minutes = 9 * 60

Minutes = 540

Hence, she practices a total of 540 minutes in the 12 days

Answer:

x=49/3

Step-by-step explanation:

move all terms that don't contain x to the right side and solve the problem.

Answer:

Step-by-step explanation:

7.  3x + 6 = 55

          - 6   - 6

  3x = 49

 /3      /3

x = 49/3  OR  x = 16.33

8.  50 = 6x + 2

    - 2          - 2

    48 = 6x

    /6    /6

     8 = x

Check/verify your answer:

50 = 6x + 2

50 = 6(8) + 2

50 = 48 + 2

50 = 50

This statement is correct.

Answer:

Erik uses 8 centimeters of tape to wrap each present.

Step-by-step explanation:

16 centimeters can wrap 2 presents.
24 centimeters can wrap 3 presents.
Add both amounts of tape together to find the total amount of tape used.  Then add the number of presents wrapped together.
16 + 24 = 40 centimeters
2 + 3 = 5 presents
40/5

In order to find how much tape wraps one present, divide both the top and bottom by the denominator (5)
40/5 = 8 centimeters
5/5 = 1 present

Erik uses 8 centimeters of tape to wrap each present.

Answer:

  y = (x/(1-x))√(1-x²)

Step-by-step explanation:

The equation can be translated to rectangular coordinates by using the relationships between polar and rectangular coordinates:

  x = r·cos(θ)

  y = r·sin(θ)

  x² +y² = r²

__

  r = sec(θ) -2cos(θ)

  r·cos(θ) = 1 -2cos(θ)² . . . . . . . . multiply by cos(θ)

  r²·r·cos(θ) = r² -2r²·cos(θ)² . . . multiply by r²

  (x² +y²)x = x² +y² -2x² . . . . . . . substitute rectangular relations

  x²(x +1) = y²(1 -x) . . . . . . . . . . . subtract xy²-x², factor

  y² = x²(1 +x)/(1 -x) = x²(1 -x²)/(1 -x)² . . . . multiply by (1-x)/(1-x)

Step-by-step explanation:

[tex]4(m - 15) = 7m + 9[/tex]

[tex]4m - 60 = 7m + 9[/tex]

[tex] - 60 - 9 = 7m - 4m[/tex]

[tex] - 69 = 3m[/tex]

[tex]m = \frac{ - 69}{3} [/tex]

[tex]m = - 23[/tex]

Hello!

4(m-15)=7m+9

4m -60 =7m +9

-60 -9 = 7m -4m

-69 = 3m

3m = -69

m = -69/3

m = -23

Answer:  x = 23

Step-by-step explanation:

The sum of interior angles in a triangles is equal to 180°, therefore:

(2x - 1) + 110 + 25 = 180

1. Get rid of parentheses.

 2x - 1 + 110 + 25 = 180  

2. Add the number up in the left side.

            2x  + 134 = 180

3. Subtract 134 from both sides.

                      2x = 46

4. Divide by 2 from both sides.

                      x = 23

Answer:

[tex]59 + 30c \leq 125[/tex]

2 rooms

Step-by-step explanation:

Given

[tex]Base\ Amount = \$59[/tex]

[tex]Additional = \$30[/tex] per carpet

[tex]Customer\ Budget = \$125[/tex]

Required

Write an inequality to determine the situation

Represent the number of carpets with c

First, we need to determine an expression for the cleaner's charges:

This is:

[tex]59 + 30 * c[/tex]

[tex]59 + 30c[/tex]

Since the customer's budget do not exceed $125.

This implies that the cleaner's charges must be less than or equal to the budget.

So, we have:

[tex]59 + 30c \leq 125[/tex]

Solving further: [Collect Like Terms]

[tex]30c \leq 125 - 59\\[/tex]

[tex]30c \leq 66[/tex]

Divide through by 30

[tex]c \leq 66/30[/tex]

[tex]c \leq 2.2[/tex]

Since number of rooms can't be fraction;

The maximum number of rooms the customer can afford is 2

his brother

Step-by-step explanation:

because 2 foot 7 inches in inches is 31 inches so therefore his brother has the longer fish.

1 foot = 12 inches.

2 feet x 12 = 24 inches + 7 = 31 inches.

Daves fish was 31 inches.

his brothers fish was bigger.

I guess, the flower bed is a true rectangle, right ?

so, then, the perimeter of that rectangle is

2×length + 2×width = 2×78 + 2×60 = 156 + 120 = 276 in.

1 ft = 12 in

276 in = 23 ft

she can only buy a bundle of 40 ft.

that means she will have

40 - 23 = 17 ft left.

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below. Follow these steps I made for you.

Step 1: Convert [tex]8\frac{4}{5}[/tex] to an improper fraction. Use this rule: [tex]a\frac{b}{c} = \frac{ac + b}{c}[/tex].

[tex]\frac{8 * 5 + 4}{5} - 5\frac{1}{10}[/tex]

Step 2: Simplify 8 × 5 to 40.

[tex]\frac{40 + 4}{5} - 5\frac{1}{10}[/tex]

Step 3: Simplify 40 + 4 to 44.

[tex]\frac{44}{5} - 5\frac{1}{10}[/tex]

Step 4: Convert [tex]5\frac{1}{10}[/tex] to an improper fraction. Use this rule [tex]a\frac{b}{c} = \frac{ac + b}{c}[/tex].

[tex]\frac{44}{5} - \frac{50 * 10 + 1}{10}[/tex]

Step 5: Simplify 5 × 10 to 50.

[tex]\frac{44}{5} - \frac{50 + 1}{10}[/tex]

Step 6: Simplify 50 + 1 to 51.

[tex]\frac{44}{5} - \frac{51}{10}[/tex]

Step 7: Find the Least Common Denominator (LCD) of [tex]\frac{44}{5}, \frac{51}{10}[/tex]. In other words, find the Least Common Multiple (LCM) of 5, 10.

LCD = 10

Step 8: Make the denominators the same as the LCD.

[tex]\frac{44 * 2}{5 * 2} - \frac{51}{10}[/tex]

Step 9: Simplify. Denominators are now the same.

[tex]\frac{88}{10} - \frac{51}{10}[/tex]

Step 10: Join the denominators.

[tex]\frac{88- 51}{10}[/tex]

Step 11: Simplify.

[tex]\frac{37}{10}[/tex]

Step 12: Convert to a mixed fraction.
