Answer:
Jimmy gets $4.2 every hour he spends doing chores or homework, if jimmy made $42 last week, how many hours did he spend doing chores or homework that week?
x = hours
y = his earnings
If LMNO is a parallelogram:
6 x - 5 = 4 x + 17
6 x - 4 x = 17 + 5
2 x = 22
x = 22 : 2
x = 11
and:
5 y + 29 = y + 25
5 y - y = 25 - 29
4 y = -4
y = -4 : 4
y = -1
Answer:
18/90=9/x and to find x use proportion so first 90*9=18x and 810=18x and x-45

Answer:
- 11, 11, 24, 34, 45 and 23
===========================
<h3>Given data</h3>
- 9, 11, 11, 16, 16, 24, 28, 30, 34, 42, 45
<h3>Five-number summary</h3>
<u>Minimum</u>:
- The smallest number of data ⇒ 11
<u>Maximum</u>:
- The largest number of data ⇒ 45
<u>Median</u>:
- The middle number of the data if data consists of odd number of elements ⇒ 24
<u>Lower quartile</u>:
- The median of the lower half of data, 9, 11, 11, 16, 16 ⇒ 11
<u>Upper quartile</u>:
- The median of the upper half of data, 28, 30, 34, 42, 45 ⇒ 34
<u />
<h3>Interquartile range</h3>
- The difference of upper and lower quartiles, 34 - 11 = 23
Answer:
The equation of parabola is standard form is
Step-by-step explanation:
Given equation of parabola is,
In order to find the equation of parabola in standard form, eliminate x from left side of equation and use completing square method to find the equation.
First step is to add x on both side of equation.
Rewriting,
Now applying completing square method as follows.
Following are the steps for calculation of this method.
Find the last term of above equation by using below formula,
Now coefficient of y is 8.
Simplifying,
Second step is to add and subtract the last term.
Rewriting,
Since
Using above formula,
Therefore, the equation of parabola in standard form is
