Answer:
Step-by-step explanation:
For women, the initial number is 6, constant rate of change is w, number of years is x.
<u>Find the rate of change and work out the required formula:</u>
- 10w + 6 = 391 ⇒ 10w = 385 ⇒ w = 38.5
<u>Formula:</u>
<u>Similarly for men, we get:</u>
- 10m + 25 = 410 ⇒ 10m = 385 ⇒ m = 38.5
<u>Formula:</u>
Answer:
a) 375
b) 7062.75 mm²
Step-by-step explanation:
b) We need to find the shortest possible width and length to get the smallest possible area.
To get the boundaries for 19.4, we go on to the next significant figure (the hundredths) and ± 5 of them.
The boundaries are, therefore: 19.35 - 19.45
As for the length, we can see they've added 5 units as the measurement is correct to 2 sig' figures, which is the tens.
And so, if we do as we did before, we go to the next sig' figure (the units) and ± 5 of them, we get the boundaries to be 365 - 375.
Now, we just multiply the lower bounds of the length and width to get the minimal/lower-bound area:
365 * 19.35 = 7062.75 mm²
Answer:
$72.15
Step-by-step explanation:
x= pounds of steak
$
= money spent on steaks
If Neil buys 7.5 pounds of steak then x =7.5
$9.62(7.5) = $72.15
He has 5 $5 bills and 10 $1 bills because 5x5=25 and 10x1=10. to check the answer you add 25+10=35.
Answer:
15
Step-by-step explanation:
If the line segment is IK, that means IJ+JK=IK. So, 7+8=15
