It takes Mia 1/4 hour to pick out all beads and 1/10 hour to string them. If she only has 5 and 1/4 to make bracelets how many w

JulsSmile [24]

Answer:

Step-by-step explanation:

Mia take 1/4 and 1/10 hours to create a bracelet. This is 1/4 + 1/10 = 10/40 + 4/40 = 14/40 = 7/20.

It takes her a total of 7/20 hours to make the bracelet. She has 5 1/4 hours to work. To find the number of bracelets she can make divide 5 1/4 by 7/20.

Write first 5 1/4 as a mixed number. 21/4. Then rewrite it as multiplication with the reciprocal of 7/20 to divide fractions.

21/4 * 20/7 = 420/28 = 15

She will make 15 bracelets.

A square has a diagonal of 44in. I want to frame the picture, how many inches of frame do I need

dimaraw [331]

The square has a 44-inch diagonal.

The pythagorean equation must be used to obtain the hand.

Diagonal (d) ^ 2 = side^2 + side ^ 2

Diagonal (d) ^ 2 = 2side (s)^2

d^2 = 2s^2

44^2 = 2s^2

1936 = 2s^2

2s^2 = 1936

s^2 = 968

s = 31.11 inches

The length of the side is around 31 inches

Perimeter = 4*s

Perimeter = 4 * 31

Perimeter = 124 inches

As a result, you will need a total of 124 inches to frame the rectangle.

Hope this helps you!!

Carlos says that 17.43 divided by 100 is the same as 174.3 times 0.01 Is he correct? Explain

Leokris [45]

Answer:

Is not correct

Step-by-step explanation:

Step 1

Find $17.43$ divided by $100$

$\frac{17.43}{100}=0.1743$

Step 2

Find $174.3$ times $0.01$

$174.3*0.01=\frac{174.3}{100}=1.743$

Compare

$0.1743\neq 1.743$

Kilo typed 1,125 words in 15 minutes let w represent the number of words typed each minute If Lolo typed the same number of word

Alborosie

Answer:

She type 75 words in 1 minute.

Step-by-step explanation:

Given:

Lolo typed 1,125 words in 15 minutes.

Let w represent the number of words typed each minute.

Now, to find the number of words she type in 1 minute if Lolo typed the same number of words each minute.

So, we solve it by using cross multiplication method:

As 1125 words is equivalent to 15 minutes.

Thus, w number of words equivalent to 1 minutes.

$\frac{1125}{15} =\frac{w}{1}$

By cross multiplying we get:

⇒ $1125=15w$

Dividing both sides by 15 we get:

⇒ $75=w$

⇒ $w=75.$

Therefore, she type 75 words in 1 minute.
