Tara has a box of 908 beads for an bracelet she wants to put 15 beads on each bracelet what is the greatest number please help me

Answers

The maximum 60 bracelets, Tara can have with 15 beads in each bracelet.

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into same number of parts.

Given, Tara has a box of 908 beads.

And one bracelet has 15 beads as per Tara's wish.

To find the number of bracelets,

we divide the total beads to beads in one bracelet.

That means,

Number of bracelets = 908 / 15= 60 (rounded)

Therefore, the maximum 60 bracelets, Tara can have with 15 beads in each bracelet.

Answer:

60 bracelets

Step-by-step explanation:

908 / 15 = 60.5

you can not have half a bead on the bracelets so round down because you only have 908 beads and do not have more.

A lion runs at a speed of 50 mph and a cheetah runs 78 mph. If they both run at a steady rate, how far will a cheetah run in the time it takes a lion to run 13.75 miles?

Answers

Answer:

21.45 miles

Step-by-step explanation:

Key:

t=time

d=distance

We need to find the time the lion ran first.

The time the lion ran:

13.75=50•t

13.75=50t

-50t=-13.75

t=-13.75•-1/50

t = 0.275

So the lion ran in 13.75 miles in 0.275 of an hour.

Now, we need to figure out the cheetah.

0.275•78=21.45 miles

I hope this helps :-)

Solve the right triangle ABC, with C = 90.00◦ , a = 15.21 cm, b = 17.34 cm. Round to two decimal places.

Answers

Answer:

  • the hypotenuse side, c = 23.1 cm
  • angle A = 41.26 ⁰
  • angle B = 48.74 ⁰

Step-by-step explanation:

Given;

first leg of the right triangle, a = 15.21 cm

second leg of the right triangle, b = 17.34 cm

Angle C = 90 ⁰

The missing parameters;

  • the hypotenuse side = c
  • angle A
  • angle B

Use Pythagoras theorem to calculate the missing side "c", which is the hypotenuse

c² = a² + b²

c² = (15.21)²  +  (17.34)²

c² = 532.02

c = √532.02

c = 23.1 cm

The missing angle A is calculated as;

tan(A) = (a)/(b) \n\ntan(A) = (15.21)/(17.34) \n\ntan(A) = 0.8772 \n\nA = tan^(-1) (0.8772)\n\nA = 41.26^0

The missing angle is calculated as;

B = 90⁰ - A

B = 90⁰ - 41.26⁰

B = 48.74⁰

Jamie went out to her grandfather's farm.
Her grandfather has pigs and chickens on his farm.
She noticed that there were a total of 26 heads and
68 feet among them. How many chickens and how
many pigs did her grandfather have?

Answers

Answer:

8 pigs

Step-by-step explanation:

Since every animal has only 1 head, a total of 26 heads suggests that there are 26 animals in total.

Suppose all animals are chickens.

Total no. of feet = 26 chickens × 2 feet

                           = 52 feet

Difference in total no. of feet = 68 feet - 52 feet

                                                = 16 feet

Difference in no. of feet each animal has

= 4 feet (a pig) - 2 feet (a chicken)

= 2 feet

∴ No. of pigs = 16 feet ÷ 2 feet

                      = 8 pigs
