Answer:

  • 5 miles = 75 minutes

Step-by-step explanation:

<u>We know that:</u>

  • 3 miles = 45 minutes

<u>Solution:</u>

  • 3 miles = 45 minutes
  • => 1 mile = 45/3 minutes
  • => 5 miles = 45/3 x 5
  • => 5 miles = 15 x 5
  • => 5 miles = 75 minutes

Hence, it takes 75 minutes for Jim to walk 5 miles.

Twenty-four minus 5 times a number is fifteen.
tankabanditka [31]

Answer:

Step-by-step explanation:

Let the number be x

5 times a number = 5x

24 - 5x = 15

-5x = 15-24

-5x = -9

x= -9/-5

x = 9/5

x=1\frac{4}{5}

or x = 1.8

the angles of a triangle are in the ratio 3:4:5. what is the degree measure of the smallest angle of the triangle?
Alik [6]
A triangle interior angles add up to 180

so we have 3:4:5
the ratio of the angles
 3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees

What is the area of this trapezoid (the right leg says 8 btw)
alekssr [168]

The answers have square roots among the choices so we probably shouldn't use that calculator button.

We can't just apply the area of the trapezoid formula

A = \frac 1 2(b + t) h

where b is the bottom base, t the parallel top, and h the height, because we don't know the top t.

It will be 10 less the leg of that right triangle, which we calculate as

l = \sqrt{8^2 - (4\sqrt{3})^2} = \sqrt{64 - 48} = \sqrt{16}=4

Now we can apply the trapezoid formula. We have

b = 10, \qquad t=10-4=6, \qquad h= 4\sqrt{3}

A = \frac 1 2(b + t) h = \frac 1 2 (10 +6)(4 \sqrt{3}) = 32 \sqrt{3}

Choice b

You Want to save money for college. You have already saved $500, and you able save $75 each week that's how much you get in a we
marusya05 [52]
You can set up an equation for this. if x is the amount of weeks, and m is total money, then it'd be
500+75x=m
plug numbers in
3 weeks: 500+75*3=$725
10 weeks: 500+75*10=$1250
6 months, each month having 4 weeks, is 24 weeks
500+24*75=$2300
