d. 12.53
C.
Answer:
9 unitsStep-by-step explanation:
Given two points:
(4, 7) and (4, - 2)The distance between them is the difference of y- coordinates since x- coordinates are same:

3. the smallest number by which 168 must be multipled to get the perfect square number. ICA) 3 1(B)2 (c) 4 (o)5
Answer:
42
Step-by-step explanation:
168 factors into
2•2•2•3•7
two of the 2's make a perfect square
(2•2)•2•3•7
2²•2•3•7
as none of the product of the remaining factors makes a perfect square
2•3 = 6, 2•7 = 14, 3•7 = 21
we need to multiply the remaining factors together to find another perfect square
2²•(2•3•7)²
2•3•7 = 42
42(168) = 7056 = 84²

Answer:
Check the attached image for the sake of my sanity typing integrals in these.
Notes on the red marks.
1. From the first to the second passage I multiplied top and bottom by 2. The bottom one stood outside the integral by linearity, the top got inside to get the derivative of the denominator.
2. Quick y substitution, it's a dy/y which should get integrated as the logarythm of the absolute value. This is a situation where you can skip it since you know that you are dealing with positive values (1 is positive, and 1 plus something squared is even greater than 1 which was positive already).
The area as x diverges also diverges

Answer:
50
Step-by-step explanation:
150 + 50 is $200.
350 - 200 is $150.
So that leaves 150 dollars left.
150/3 is 50 people.
Answer:
50 guest is the answer.
Step-by-step explanation:
...so:
$350-$150 for the DJ
$200-$50 for the cake.
and, $3 per party guest for food.
That would be:
$150/$3 = 50 guest.
If the side of a square is increased by 25%, then by how much is its area increased?
Answer:
56.25%Step-by-step explanation:
If a variable X changes by A% and another variable Y changes by B%, then overall net change when the two variables are multiplied is given by :
A + B + AB/100
If the change is “increase” it is positive & if the change is “decrease” it is negative.
In the given question, A = B = 25% ( Both positive as length increase )
And area = Side x Side
Applying our versatile relation :
Net increase in area = 25 + 25 + (25x25)/100 = 56.25%
At a pumpkin stand, Fei bought 3 pumpkins: one large, one medium, and one small. The large pumpkin cost twice as much as the medium one, and the medium pumpkin cost three times as much as the small one. Fei spent $20 in total. How much did the large pumpkin cost?
Answer:
Step-by-step explanation:
lets put the small pumpkin as x that means medium is 3x and large is 6x
so we have a equation
x+6x+3x=20
combine them
10x=20
divide by 10
x=$2
