65 x 25 5 help me plsssss

Ernest rode his bike 8 1/4 hours on Saturday and 6 1/4 on sunday he rode for a total of 88 1/2 miles for both days how long does

irina [24]

Saturday and Sunday: 8 1/4 hours + 6 1/4 hours = 33/4 + 25/4 = 58/4 = 29/2 hours = 14 1/2 hours

A total of 88 1/2 miles = 177/2 miles for both days.

If you would like to know how long does it take him to ride one mile on his bike, you can calculate this using the following steps:

88 1/2 miles ... 14 1/2 hours
1 mile ... x hours = ?

88 1/2 * x = 1 * 14 1/2
177/2 * x = 29/2 /*2
177 * x = 29 /177
x = 29/177 hours
x = 0.16 hours

Result: It takes him 0.16 hours to ride one mile on his bike.

A large beach ball has a diameter of 4.14 feet. How much air can fill the ball?

aalyn [17]

The beach ball can hold 37.15 cubic feet of air

Solution:

Given that the beach ball has a diameter of 4.14 feet

We are asked to find how much air can fill the ball. This means that we have to find the volume of the ball

Finding volume of ball:

Given diameter = 4.14 feet

We know that radius is half of diameter

$radius = \frac{diameter}{2}$

$radius = \frac{4.14}{2} = 2.07$

Since ball is a sphere, Volume of sphere is given as:

$volume of sphere = \frac{4 \pi r^3}{3}$

By substituting the value of radius we get,

$v = \frac{4 \pi \times 2.07^3}{3}\\\\v = \frac{4 \times 3.14 \times 8.869743}{3}\\\\v = 37.15$

Hence the beach ball can hold 37.15 cubic feet of air

What additional information is needed to determine that ΔABC ≅ ΔEDC using the HL method of congruence? answers: A) ≅ B) No addit

Savatey [412]

Answer:

AC congruent to EC

Step-by-step explanation:

This problem is asking specifically to prove triangles congruent using HL.

HL is a method of proving triangles congruent. HL stands for Hypotenuse-Leg. If you can show that the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg, respectively, of another triangle, then the triangles are congruent.

Looking at triangle ABC and EDC, we see that the legs AB and ED are congruent. We already have a pair of corresponding congruent legs. Now we need a pair of hypotenuses.

You need AC congruent to EC.

A label prints in the pediatric pharmacy

Elden [556K]

Answer:

107.14 ml of 70% dextrose and 392.86 ml of sterile water should be used.

Step-by-step explanation:

Since a label prints in the pediatric pharmacy satellite for 500 mL of dextrose 15% solution, but this concentration is not available commercially and needs to be compounded, and available in your pharmacy, you have a 1 L bag of sterile water and a 1 L bag of dextrose 70% available to compound the solution, to determine how many mLs of each are needed to make the requested solution, the following calculation must be performed:

500 x 0.15 = 75

100 x 0.70 = 70

A x 0.70 = 75

A = 75 / 0.70

A = 107.14

Therefore, 107.14 ml of 70% dextrose and 392.86 ml of sterile water should be used.
