Answer:

33.11 hope this helps

Step-by-step explanation:

she needs to pay $33.108 In order to leave a 24 percent tip.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, Josefina's check at Sun Bistro is $26.70. she wants to leave a 24% tip

Bill of josefina = 26.70

Bill after 24% tip = 26.70 * (1 + 24%)

Bill after 24% tip = 26.70 * 1.24

Bill after 24% tip = 33.108

Therefore, In order to leave a 24% tip she needs to pay $33.108.

The domain is the set of all the x-values/inputs used by the function.  

The range is the set of all y-values/outputs used by the function.

For #1:

The domain is { 1, 0, -1, 4 } because those are the x-values.

The range is { 3, 5, 7, -6 } because those are the x-values.

Answer:

This is quite an easy question u should try it yourself

Step-by-step explanation:

The formula is

V= d / t

Therefore the distance is

D = vt

So since they alredy gave u that v = 20m/s

Answer:

B

Step-by-step explanation:

Since the line bisect PQ then the length of the left segment must be equal to the right segment.

Hence

[tex]5x-3 = 11 -2x\\5x + 2x = 11 +3\\7x = 14\\x = 2[/tex]

When x = 2 we have

[tex]PM = 5(2) -3 = 10 -3 =7.[/tex]

So the answer is B

Answer:

b. B

Step-by-step explanation:

PM = RM

[tex]5x - 3 = 11 - 2x[/tex]

[tex]5x + 2x = 11 + 3[/tex]

[tex]7x = 14[/tex]

[tex]x \times 2[/tex]

Answer:

(-2.5 , 1)

Step-by-step explanation:

the x- coordinates :

[(3×(-2)) + (1×(-4))] /(3+1)

= (-6 +(-4))/(4)

= -10/4

= -2.5

the y-coordinates :

[(3×(-2)) + (1×10)] / (3+1)

= (-6+10)/(4)

= 4/4

= 1

so, the coordinates are (-2.5 , 1)

Answer:

Step-by-step explanation:

Directed line segment from (−4,10) to (-2, -2).

The ratio = 3/1.

The coordinates are:

here,

a= 7 and b=10

then,

ab

= a × b

= 7 × 10

(replace a and b by its value)

= 70

therefore, ab =70......

Answer:

55,000

55,183 is closer to 55,000 than to 56,000

To round to the nearest thousand look at the hundreds number, if the number is below 5 then the thousands number remains the same and the digits less than the thousands become zeros, if the hundreds number is 5 or higher you add 1 to the thousands number and the digits less than the thousands become zeros.

The hundreds number is 1, so the thousands number remains 5.

Step-by-step explanation:

x+y = 5

Put this equation in slope intercept form y = mx+b where m is the slope

y = -x +5

The slope of the line is -1

Perpendicular lines have slopes that multiply to -1

-1 * m = -1

m = 1

The slope of the perpendicular line is 1

Answer:

if i am rightthe two other angles arre 39

Step-by-step explanation:

if a triganle is 180 degrees and you have already one angle then all you do is subtract 180 and 102

180-102= 78

then since you need the other two angles all you do is divide it by 2

so 78/2= 39 so the two missing anlges are 39

⅑y - 5 = -7
