On a normal day, I can walk from my house to school in three quarters of an hour. The return trip takes me the same amount of ti

me. My mom, driving our car, covers that distance in about a quarter of the time that it takes me. If I go to school five days a week and there are thirty-seven weeks in the school year,
how many hours would I save every year if my mom agreed to drive me to and from school?

Answer:

  208 1/8 hours

Step-by-step explanation:

The amount of time saved on each trip is ...

  (3/4 h) - (1/4)(3/4 h) = (3/4)(3/4 h) = 9/16 h

There are 2×5×37 = 370 trips in the school year, so the total savings in time is about ...

  370×(9/16 h) = 208 1/8 h

Can someone help me with this
sweet-ann [11.9K]
As this is a fraction, we need to find values where the denominator is equal to 0.

b^2-2b-8=0
(b-4)(b+2)
b=4 \vee b=-2

So the answer is B.

A group of children, adults, and senior citizens attended three different art exhibits that have different ticket prices for eac
anastassius [24]

Answer:

c = 100, a = 50, s = 20

Step-by-step explanation:

following information is missing from the question

6c + 7a + 2s = 990

3c + 3a + 4s = 430

2c + 4a + 4s = 480

If you solve the equation by putting in the values given in the option you will deduce that only option d matches LHS to the RHS

Lets see how,

6c + 7a + 2s = 990                

where, c = 100, a = 50, s = 20

6(100) + 7(50) + 2(20) = 990

600 + 750 + 40 = 990

990 = 990 hence true

2c + 4a + 4s = 480                     where, c = 100, a = 50, s = 20

2 (100) + 4 ( 50) + 4 (20)  = 480

200 + 250 + 80  =  480

See for the other option too with the same steps done above  to have a more clear understanding :)

Match the slope and y-intercept with the correct linear equation. Question 1 options: m = -2, b = 3 m = 23, b = -25 m = 3, b = 5
scoray [572]

Answer:

  • m = -2,\ b = 3 → Equation 2 (y =-2x+3)
  • m =23,\ b =-25 → Equation 3 (y=23x - 25)
  • m = 3,\ b = 5 → Equation 1 (y=3x + 5)

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

Knowing this,  and having the equations provided in the exercise, you can identify the slope and  the y-intercept of each line.

- In Equation 1:

y=3x + 5\\\\\\m=3\\b=5

 - In Equation 2:

y =-2x+3\\\\\\m=-2\\b=3

 - In Equation 3:

y=23x - 25\\\\\\m=23\\b=-25
