Answer:
$109.38
Step-by-step explanation:
The time worked was ...
(12:00 -8:00) +(17:30 -12:45) = 4:00 + 4:45 = 8:45 . . . . hours:minutes
This is 8 45/60 hours = 8 3/4 hours = 8.75 hours.
The pay for 8.75 hours is ...
8.75 × $12.50 = $109.375 ≈ $109.38
Answer:
Part A: Number of cups of blue paint are 3 that are mixed with each cup of red paint.
Part B:
Part C:<em> $8</em>
Step-by-step explanation:
Given that:
The ratio of the number of cups of blue paint to the number of cups of red paint that Lara mixed to make a shade of purple paint is 3:1.
Part A:
The number of cups of blue paint = 3
The number of cups of red paint = 1
In sentence form, it can be written that:
Number of cups of blue paint are 3 that are mixed with each cup of red paint.
Part B:
3 cups of blue paint requires 1 cup of red paint.
cup of blue paint requires cup of red paint.
Here, unitary method is used.
So, cup of red paint should be added to each cup of blue paint to make shade of purple.
Part C:
6 cups of blue paint are purchased for $48.
1 cup of blue paint is purchased for
Answer
Length measured using Ruler A= 1.17 dm
Length measured using Ruler B=1.18 dm
Step by Step Explanation:
I have added the missing photograph which shows the length of pencil being measured with two rulers.
Ruler A has marking separated by 1 dm
Ruler B has marking separated by 0.1 dm
Length measured using Ruler A= 1.17 dm
(As we can see I have added the middle markers, we can see the tip of pencil is somewhere between 1 and 1.25, it is more than 1.125 but lesser than 1.25, it is somewhere around 1.2 and 1.125 dm, approximately equal to one half of 1.25 which is 1.125 with addition of one of the three halves of half of 1.125 which is 1.125+0.045 dm hence 1.17dm)
Length measured using Ruler B=1.18 dm
(we can see the tip of pencil is just before 1.2 dm, it is clear that the value is precisely 1.18 and not 1.19 dm)
<u><em>Tip:Always measure one more decimal than given by the ruler when unsure about the exact value</em></u>
Answer:
There are 15 numbers of chicken and 25 numbers of bulls.
Step-by-step explanation:
The pen had chickens and bulls. The pen contains 40 animals in total. The number of legs in the pen is 130 .
Let
a = number of chicken
b = number of bull
a + b = 40................(i)
A chicken has 2 legs and a bull has 4 legs.
The total legs can be represented as
2a + 4b = 130...........(ii)
combine the equation
a + b = 40................(i)
2a + 4b = 130...........(ii)
a = 40 - b
insert the value of a in equation(ii)
2(40 - b) + 4b = 130
80 - 2b + 4b = 130
80 + 2b = 130
2b = 130 - 80
2b = 50
divide both sides by 2
b = 50/2
b = 25
Insert the value of b in equation (i)
a + b = 40
a + 25 = 40
a = 40 - 25
a = 15
There are 15 numbers of chicken and 25 numbers of bulls.
