Answer:

5.29

Step-by-step explanation:

Two Decimal Places Rule #1: If the last digit in 5.275 is less than 5, then remove the last digit. Two Decimal Places Rule #2: If the last digit in 5.275 is 5 or more and the second to the last digit in 5.275 is less than 9, then remove the last digit and add 1 to the second to the last digit.

Hope it helps :)

pls mark brainliest :P

** Which of the following is parallel to the line 2x + 4y = 16 (A) y = 2x + 5 (B) y = -x + 4 (C) y = -x + 8 (D) y = 2x + 5 =-

andreev551 [17]

Answer:

None of them.

Step-by-step explanation:

Each and every straight line is of one kind in terms of its pattern: it can be presented in the view of $y = kx + b$ : $k$ is the slope or gradient of the line, $b$ is the y-intercept of the line. I will not let the cat out of the bag if I say that any parallel lines do not intersect one another, hence they should have the same value of coefficient $k$ .

$2x + 4y = 16 \Leftrightarrow x + 2y = 8 \Leftrightarrow 2y = -x + 8 \Leftrightarrow y = - \frac{1}{2}x + 4$

Therefore, our line has $k = - \frac{1}{2}$ and $b = 4$ coefficients.

(A) $k = 2, b = 5;$

(B) $k = -1, b = 4;$

(С) $k = -1, b = 8;$

(D) $k = 2, b = 5;$

Recapitulating this: none of them have the same coefficient $k$ , thus none of them suit us.

In a parallelogram whose area is 15, the base is represented by x+7 and the altitude x-7. Find the base of parallelogram.

Sati [7]

Area = (base)*(height)
15 = (x+7)(x-7)
(x+7)(x-7) = 15
x^2 - 49 = 15
x^2 - 49+49 = 15+49
x^2 = 64
sqrt(x^2) = sqrt(64)
x = 8 ... note that x can't be negative

If x = 8, then the base is...
x+7 = 8+7 = 15

Therefore the base is 15 units.
(the height is x-7 = 8-7 = 1 unit)

The Candy Factory sells candy by the pound, charging $1.60 per pound for quantities up to and including 20 pounds. Above 20 poun

rusak2 [61]

Answer:

$k=6$

Step-by-step explanation:

We have been given that the Candy Factory sells candy by the pound, charging $1.60 per pound for quantities up to and including 20 pounds. Above 20 pounds, the Candy Factory charges $1.30 per pound for the entire quantity, plus a quantity surcharge k.

$\left \{ {{p(x)=1.6x, \text{ If }x\leq 20} \atop {p(x)=1.30x+x,\text{ if }x>20}} \right.$

For the price function be to continuous at $x=20$ , the value of both functions at $x=20$ must be equal. Because a function is continuous if the right hand limit is equal to left hand limit.

$1.6(20)=1.3(20)+k$

Let us solve for k.

$32=26+k$

$32-26=26-26+k\\\\6=k$

Therefore, the price function p is continuous at $x=20$ , when k is equal to 6.
