Answer:
. The sweaters cost $10 or less each. We graph it on a number line at 10 and use a filled in dot pointing towards zero for less than.
Step-by-step explanation:
Mrs. Smith buys 3 sweaters (represented by 3s) and 2 jeans (represented by 2j) for a total of at most $120. We don't know the total but we do know she couldn't spend more than $120.
We write .
We know the jeans cost $45 each, so j=45. We substitute,
We solve for s by subtracting 90 to the other side and dividing the result by 3.
.
The sweaters cost $10 or less each.
Answer:
16
Step-by-step explanation:
(2 means squared) (c is the hypotenuse)
a2+b2=c2
a2+ (12×12) = (20×20)
a2+144=400
a2=256
a=16
This is an incomplete question, here is a complete question.
A hurricane wind blows across a 7.00 m × 12.0 m flat roof at a speed of 150 km/h.
What is the pressure difference Δp = p(inside)-p(outside)? Use 1.28 kg/m³ for the density of air. Treat the air as an ideal fluid obeying Bernoulli's equation.
Answer : The pressure difference will be, 
Step-by-step explanation :
As we are given:
Speed = 150 km/h = 41.66 m/s
Density = 
Area = A = 7.00 m × 12.0 m
Formula used :
Now put all the given values in this formula, we get:
Thus, the pressure difference will be,
Answer:
<u>
3.582</u>
Step-by-step explanation:
Find the number in the thousandth place 2 and look one place to the right for the rounding digit 3
. Round up if this number is greater than or equal to 5 and round down if it is less than 5
.
3.582

No, (9.5, 144) does not make sense because there is no point of 9.5 and when you divide the ounces of water by the flavoring packets you end up with 12, and if you were to simplify that it would end up with 1 flavor packet and 12 ounces of water.
