Answer:
2 hours and 45 minutes
Step-by-step explanation:
you add the 15 and 30 and then add 2 hours.
Ana spent 2 hours and 45 minutes working.
What is Unitary Method?Unitary method is a technique used in mathematics to solve problems that involve proportional relationships. It involves finding a unit rate (i.e., a rate per unit) and using it to solve problems that involve different quantities of the same type of unit.
To find the amount of time Ana spent working, we need to subtract the starting time from the finishing time.
The starting time is 2:45 pm and the finishing time is 5:30 pm.
We can subtract the starting time from the finishing time as follows:
5:30 pm
2:45 pm
2:45 pm
So, Ana spent 2 hours and 45 minutes working.

Jessica plans to plant a garden 55 feet away from her house. On a map of her backyard, she drew the garden 22 inches away from the house. Complete the scale: 1 in. = ?.
Answer:
1 inch = 2.5 feet
Step-by-step explanation:
Jessica plans to plant a garden 55 feet away from her house.
On a map of her backyard, she drew the garden 22 inches away from the house.
From the above question, we know that:
22 inches = 55 feet
1 inch = x
Cross Multiply
22 inches × x = 1 inches × 55 feet
x = 1 inches × 55 feet/22 inches
x = 2.5feet.
Therefore, the scale is given as: 1 inch = 2.5 feet

Hint
$15; the cost per muffin
o $2; the cost per muffin
O $2; the cost per order
$15; the cost per order
Answer:
:)
Step-by-step explanation:
It should be $2; the cost per muffin
The cost of one muffin is $2.
What is subtraction?Subtraction is mathematic operation. Which is used to remove terms or objects in expression.
Given, $15 is delivery cost of muffins.
That means the if x is the cost of one muffin then
Total cost = nx + $15
,where n is the number of muffins.
Now,
for n = 1
The total cost of one muffin is :
17 = x + 15
x = 2
Therefore, the cost of one muffin is $2.

What will happen to the graph of the line y = -5/4x + 3 if you change -5/4 to 5/4?
I will give u a brainlist
Answer:
The slope of the line will change from negative to positive
Step-by-step explanation:
The equation of the line, y = -⁵/4 x + 3, is written in the slope-intercept form, which is y = mx + b. Where,
Slope = m, which means the slope of the line is -⁵/4,
y-intercept = b, which means the y-intercept of the line is 3.
Therefore, if -⁵/4 is changed to ⁵/4, the slope has been changed from negative to positive. Therefore, the graph of the slope of the line will change from negative to positive.

What is x, the distance between points A and A'?
A.2.4 units
B.4.8 units
C.13.6 units
D.14.4 units
Answer= C
Answer:
2.24units
Step-by-step explanation:
Let the coordinate be A(3, -5) and A'(2, -3)
Using the formula for calculating the distance between two points
D = √(x2-x1)²+(y2-y1)²
AA' = √(2-3)²+(-3-(-5))²
AA' = √(-1)²+(-3+5))²
AA' = √1+2²
AA' =√5
AA' = 2.24 units
Note that the coordinate points are assumed
