ΔABC ~ ΔDEF

that means the ratio of DF to AC = the ratio of DE to AB

x:3.5 \\6:4

cross multiply

4x=6(3.5)\\4x=21\\x=\frac{21}{4}\\ x= 5.25

so DF = 5.25 cm

Katen [24]

Answer:

$17.35/h

Step-by-step explanation:

In order to get the amount per hour he made, you first need to calculate the global amount of money he made.

He was paid $2,900 then he had costs of $1,200, that leaves him a net income of $1,700 ($2,900 - $1,200)

Then he worked a total of 98 hours for that money.

A salary is an amount of money expressed by a period of time.  In this case, we'll use hours.

So, Jonah earned $1,700 after 98 hours of work:

S = $1,700 / 98 hours = $17.35/h

To find the mean: You have to add them all together, then divide them by how many numbers there are.
 
So: 23+25+32+35+36+25+27 = 203

How many numbers did we add up? 7.

203 ÷ 7 = 32.85714 (That is the mean rounded up to the nearest hundredth thousandth).

Mrrafil [7]
X will be used for the value of money she earned that week.

H represents the normal hours she worked.

D represents the number of days.

Y will represent the hours on the holiday.

Since she would be getting time and a half on the holiday, you would need to find how much time and a half pay would be first.

Time and a half = 5.50(1/2) + 5.50 = $8.25/hr for the day or holiday only.

X = 5.50(H)(D) + 8.25(Y)

Plug in your numbers

X = 5.50(7)(5) + 8.25(4)

X = 192.5 + 33

She made $225.5 that week.
