$3.99 rounded to 4$ X 2=$8 for 25 for. oz

$6.99 rounded to $7 X 2 =$14 for 90 fl. oz

so $6.99 is cheaper

Answer:

33

Step-by-step explanation:

The product of the secant segment lengths is a constant.

... TC×CV = UC×CW

... 14(2x+2) = 12(2x+5) . . . . substitute the values from the diagram

... 28x +28 = 24x +60 . . . . eliminate parentheses

... 4x = 32 . . . . . . . . . . . . . . add -28-24x

... x = 8 . . . . . . . . . . . . . . . . divide by 4

UW = 12 + 2x + 5 = 17+2·8 . . . . UW = UC + CW

UW = 33

kodGreya [7K]

Answer:

324 minutes or 5 hours 24 minutes

Step-by-step explanation:

On Tuesday, Saima rode her bike for 52 miles. If it takes Saima 6 minutes to ride each mile, then it takes her

52\cdot 6=312

minutes to ride all 52 miles.

Before she rides her bike, Saima warms up for 12 minutes.

Therefore, it takes Saima

12+312=324

minutes to warm up and ride her bike on Tuesday.

Suppose the graph of a cubic polynomial function has the same zeroes and passes through the coordinate (0, –5). Describe the ste
olga_2 [115]
1. "the graph has the same zeros" : so let a be the "triple" root of the cubic polynomial function.

2. So f(x)=(x-a)^{3}

3. Don't forget that the expression might have a coefficient b as well, and still maintain the conditions: 
 
f(x)=b(x-a)^{3}

4. Now, f(0)=-5 so  -5=f(0)=b(0-a)^{3}=b(-a) ^{3}=-ba ^{3}

-5=-ba ^{3}

5=ba ^{3}

b= \frac{5}{ a^{3} }

5. the function is f(x)=\frac{5}{ a^{3} }(x-a)^{3} where a can be any real number except 0

The complement of angle a is 20° less than half the supplement of angle a. find the measure of angle a.
igor_vitrenko [27]

Answer:

∠a=40°

Step-by-step explanation:

complement of angle a=90-a

supplement of angle a=180-a

90-a=1/2(180-a)-20

multiply by 2

180-2a=180-a-40

180-180+40=-a+2a

a=40
