287.25 miles in 5.75 hours

Step-by-step explanation:

so he was first driving at 48mph because 168/3.5=48

5 miles per hour faster than that is 53mph

53*2.25=119.25

Roger is building a frame for a flower bed. He is using left-over scraps of wood from his garage. He needs a total of 12 feet of

Korolek [52]

Answer:

C. No, because 11.34 < 12

Step-by-step explanation:

3.14 + 4.12 + 4 has to be greater than or equal to 12

solve the equation

3.14 + 4.12 + 4 >= 12

7.26 + 4 >= 12

11.26 >= 12 is false

I don't know why it says 11.34 because the numbers don't add up, so I'll assume that there is a typo somewhere.

Find the slope of each line. PLS HELP TYSMMMM!

umka2103 [35]

Answer:

Step-by-step explanation:

1. (-4, -2) (4, 0)

(0 + 2)/(4 + 4)= 2/8= 1/4

2. (-1, 2) (1, -3) = (-3 - 2)/(1 + 1) = -5/2

3. (-2, 3) (0, 0) = (0 - 3)/(0 + 2) = -3/2

4. (1, 1) (3,2) = (2 - 1)/(3 - 1)= 1/2

Two bikers, Derek and Tina, start riding from the same location. Derek rides due west for x miles. Tina goes due south and cover

kirza4 [7]

Answer: Tina rides 4 miles and Derek rides 3 miles.

Explanation:

Since we have given that

Distance covered by Derek in west direction be x

Distance covered by Tina in south direction be x+1

Distance between the bikers when they both stop is x+2

Since it forms right triangle, so we will apply "Pythagorus theorem":

$H^2=P^2+B^2\\\\(x+2)^2=x^2+(x+1)^2\\\\x^2+4x+4=x^2+x^2+1+2x\\\\x^2+4x+4=2x^2+2x+1\\\\x^2-2x^2+4x-2x+4-1=0\\\\-x^2+2x+3=0\\\\x^2-2x-3=0\\\\x^2-3x+x-3=0\\\\x(x-3)+1(x-3)=0\\\\(x+1)(x-3)=0\\\\x=-1,3$

Since distance can't be in negative sign, so we take x=3 miles

Derek rides 3 miles

Tina rides is given by

$x+1=3+1=4\ miles$

Hence, Tina rides 4 miles and Derek rides 3 miles.
