Answer: width is 12, length is 16
Step-by-step explanation:
A= l*w
l=w+4
A=w(w+4)
factor
(w+16)(w-12)
w= -16 or w=12
width is 12, length is 16
Answer:
it would be a 60%
Step-by-step explanation:
Divide 84 by 140, and you get .6
Hope this helps!!
1 hour = 60 minutes.
Divide the number of words per hour by 60:
86 / 60 = 1.433333
Rounded to the nearest tenth = 1.4 words per minute.
Answer:
B) 16 ft, 10.5 in
Step-by-step explanation:
There are a few different ways you can work this. Since we want to know the difference between length and heigh of the model and we are given skull length of the model, it makes a certain amount of sense to find the corresponding measurements of the actual skeleton.
The actual skeleton's length was 40 ft and its height was 13 ft, so the difference between these dimensions is ...
40 ft - 13 ft = 27 ft
The actual skull is 5 ft long, so the difference is ...
(27 ft)/(5 ft) = 5.4
times the length of the skull.
The same ratio will apply to the model, so the difference between the model height and model length is 5.4 times the length of the model skull:
desired difference = 5.4 × 3 ft 1.5 in = 16.2 ft + 8.1 in
= 16 ft 10.5 in
Making a profit means ending the month with a number above 0, so your inequality will have to be greater than 0.
(sell) t-shirt = 12
(make) t-shirt = 6.50
and a constant of 150
so your current equation will be the cost of making a t-shirt, the money received by selling, and the cost of rent. it'll look like:
12t - 6.50t -150 > 0
but you want to get t alone to know how many t-shirts you have to sell, so solve the inequality:
12t - 6.50t - 150 > 0
12t - 6.50t > 150
5.50t > 150
t > (150/5.50)
and that fraction is roughly 27.27, so you'll round it up to the next whole number because alex can't make/sell a twenty-seventh of a t-shirt.
alex will have to make 28 t shirts to make a profit, and you can plug it back into the equality like so to check it:
12t - 6.50t - 150 > 0
12(28) - 6.50(28) - 150 > 0
336 - 182 - 150 > 0
4 > 0
and that statement is true, measly profit as it is.
