Answer:
approx. 3 hours
Step-by-step explanation:
14 newspapers in 20 minutes means he can deliver 42 newspapers an hour.
60/42 = 1.4285 newspapers per minute
131 x 1.4285 = 187.1335 minutes = 3.1188 hours
Answer:
6250
Step-by-step explanation:
Fill in the given number and solve for x. The answer is 1000x, rounded.
x is in thousands, so 6.25×1000 = 6,250 passengers flew in June.
Answer:
56
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
20(32 + ?) = 1760 ( divide both sides by 20 )
32 + ? = 88 ( subtract 32 from both sides )
? = 56
Pat's fund earned is $526.40 more than Sam's fund.
Sam's investment :
9400*.052 = 488.80*7 = $3,421.60
Pat's investment :
9400*.06 = 564*7= $3,948.00
$3,948.00-$3,421.60=$562.40
The answer to your question is going to be D. $526.40.
Hope this helps you!!:))
Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
