Answer:
Hence, Rashida will be paid $960 for 40 hour work.
Step-by-step explanation:
Rashida was paid $720 for 30 hours of work.
that means the amount she is being paid fro 1 hour of work is:
Hence she is paid $24 for 1 hour work.
Now we have to find how much amount she is being paid for 40 hour of work:
Amount paid for 1 hour=$24
Amount paid for 40 hour=$ (24×40)=$960.
Hence, Rashida will be paid $960 for 40 hour work.
Answer:
Jillian is Incorrect as fraction can never be balanced based on numerator or denominator.
Step-by-step explanation:
Given:
Measure of ribbon Kiara has =
Measure of ribbon Jillian has =
Now given:
Jillian says their ribbons are equal in length because her numerator is one more than kiara's and her denominator is one less, therefore balancing the two fractions.
we need to find whether statement is correct or not.
First we will find the decimal value of the given fraction's
can rewritten as
Measure of ribbon Kiara has = 0.25 inch
can be Rewritten as
Measure of ribbon Jillian has = 0.67 inch
Now we can see that;
0.67 inch is greater than 0.25 inch.
Hence we can say that ribbons are not in equal length.
Also the fraction can never be balanced by decreasing or increasing the numerator or denominator.
B. 39.25 square inches
C. 39.25 inches
D. 78.5 square inches
The area of table is 78.5 square inches.
A figure's area is the amount of space it takes up in two dimensions. To put it another way, it is the number that tells how many unit squares cover the surface of a closed figure. Square units, such as square inches, square feet, and so on, are the standard measurement for area.
Given the diameter of dinner plate = 10 inches
shape of plate is circular
area of circle is πr²
where r is radius
r = d/2 = 10/2 = 5 inches
A = πr²
A = 3.14(5)²
A = 3.14 x 25
A = 78.5 square inches
Hence area is 78.5 square inches.
