y varies jointly as x and z. If y = 12 when x = 4 and z = 3, find y when x = 9 and z = 8.
Answer:
y = 72
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 12 when x = 4 and z = 3
12 = k × 4 × 3 = 12k ( divide both sides by 12 )
1 = k
y = xz ← equation of variation
When x = 9 and z = 8 , then
y = 9 × 8 = 72
If the height of a cone is 7.5 cm and the radius is 2 cm, find the approximate volume of the cone.
Answer:
The volume of the cone is approximately 31.43 cm³Step-by-step explanation:
We know that:
Volume of cone: πr²h/3h = 7.5r = 2Work:
πr²h/3=> π x r² x h/3=> 22/7 x 2² x 7.5/3=> 22/7 x 4 x 2.5=> 22/7 x 10=> 220/7=> 31.43 (Rounded to nearest hundredth.)Hence, the volume of the cone is approximately 31.43 cm³

Sam made $189 for 9 hours of work. At the same rate, how many hours would he have to work to make S147?
Answer: 7 hours
Step-by-step explanation:
$189/9 hr = $21/hr
$21/hr(x) = $147
x = 147/21
x = 7 hours
Answer:
7 hours
Step-by-step explanation:
We know 9 hours of work paid $189
to find how much Sam makes in one hour we divide the amount made by the time it took to make it
189 / 9 = 21 dollars per hour
then we know she would like to make $147 more at a rate of $21/hr so
147 / 21 = 7 hours

One evening, 2/3 of Mrs. Thorne’s students watched a reality television show. Of Mrs. Lombardo’s students, 4/5 watched the same reality show: Which teacher has more students watch the reality show?
Answer:
They both had the same amount of students watch the reality show.
Step-by-step explanation:
To find the number of students who watched the reality show in each teacher's class, just multiply the fraction by the total number of students per teacher.
For Mrs. Thorne's:
36 * (2/3) = 24 students
For Mrs. Lombardo's:
30 * (4/5) = 24 students
24 = 24 so they had an equal amount of students from each class watch the reality show.

Step-by-step explanation:
The slope of linear equations can be determined by m = rise / run. Rise means the difference between the y coordinates of the two points, and run is that of the y coordinates. In this case rise / run = (7-5) / (4-1) = 2 / 3.

A Dog’s grew 2 1/2 inches in 12 1/2 weeks.How long will the hair grow in 1 week
Using the principle of proportional relationship, the length of hair grown by the dog in 1 week would be 0.2 inches
Setting up the relationship thus :
12.5 weeks = 2.5 inches
1 week = p inches
Cross multiply
12.5p = 2.5
Divide both sides by 12.5
p = 2.5 / 12.5
p = 0.2 inches
Hence, the length grown in 1 week is 0.2 inches
