a small dog’s heart beats about 530,000,000 times during its lifetime, and a large dog’s heart beats about 1.4 times this amount. What is the approximate number of heartbeats in the lifetime of a large dog?

Answers

Answer 1

Answer:

I think the answer is 742,000,000

Step-by-step explanation:

Answer 2

The approximate number of heartbeats in the lifetime of a large dog is 742,000,000 times.

What is unitary method?

Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

According to the question

A small dog’s heart beats about during its lifetime = 530,000,000 times

A large dog’s heart beats about 1.4 times this amount.

i.e A large dog’s heart beats about during its lifetime = 530,000,000 *1.4  times

                                                                                     =  742,000,000 times

Hence, the approximate number of heartbeats in the lifetime of a large dog is 742,000,000 times.

question 3/4

Answers

Answer:

i am having trouble with that too

Step-by-step explanation:

Answer:

Since we are told that the two given polygons are said to  similar, their corresponding side lengths are proportional to each other.

so to solve

(x - 3)/2.5 = 16/4

(x - 3)/2.5 = 4

Multiply both sides by 2.5

x - 3 = 4 × 2.5

x - 3 = 10

Add 3 to both sides

x = 10 + 3

x = 13

So the value of x is 13.

Step-by-step explanation:

m∠2 = 52° [Alternate interior angles]

m∠1 + m∠2 = 180° [Linear pair of angles are supplementary]

m∠1 = 180° - 52°

m∠1 = 128°

m∠3 = 47° [Alternate interior angles]

m∠5 + 52° + 47° = 180° [Sum of linear angles is 180°]

m∠5 = 180° - 99°

        = 81°

m∠4 + 47° = 180° [Sum of consecutive interior angles is 180°]

m∠4 = 180° - 47°

m∠4 = 137°

What is the probability that the first lands on an odd number and the second lands on an even number?


Enter you answer, as a fraction in simplified form, in the box

Answers

Answer:

1/4

Step-by-step explanation:

Assuming the number cube is a six-faced die, you have

1 2 3 4 5 6

three odd numbers, and three even numbers. Therefore, the chance of it landing on an odd number or even number is 3/6, which equals 1/2. That means you have a 50% chance to get an odd number, or an even number.

So, you have two die. Both have a 50/50 chance of getting an even or odd number. So what's the chance of one landing on an odd number, and the other landing on an even number?

You would have a 25% chance for an even and then an even numberYou would have a 25% chance for an odd and then an odd numberYou would have a 25% chance for an even and then an odd numberYou would have a 25% chance for an odd and then an even number.

Tea bags are sold in three sizes of box. A small box of 50 tea bags costs £2.15 A medium box of 80 tea bags costs £3.29 A large box of 125 tea bags costs £5.17 Which size of box is the best value for money?

Answers

Answer:

medium box

Step-by-step explanation:

The computation is shown below:

For small box,

= £2.15 ÷ 50

= £0.043

For medium box

= £3.29 ÷ 80

= £0.041125

And, for large box

= £5.17 ÷ 125

= 0.04136

So as per the above calculation the medium box should represent the best value for the money

You want to frost a 13 in. by 9 in. cake that you just baked when you notice your little brother ate a piece right out of the middle. What area of cake is left to be frosted if he ate a 2 in. by 2 in. piece? no links pls :) thanks will give brainliest

Answers

Answer:

113 inches

Step-by-step explanation:

13 times 9 is 117 inches (this is the area for the whole cake)

2 times 2 is 4 (this is just the middle)

But since the brother ate the middle you will have to subtract the area of the middle piece from the whole area.

117-4 is 113 so the area now is 113 inches

60 tickets to a concert was sold. Adult tickets cost $5 while children’s tickets cost $3.50. A total of $250 was collected. How many adult and children tickets were sold?

Answers

Answer:

Number of adults tickets sold = x

= 26.67 tickets

Number of children tickets sold = y = 33.33 tickets

Step-by-step explanation:

Let

Number of adults tickets sold = x

Number of children tickets sold = y

x + y = 60 (1)

5x + 3.50y = 250 (2)

From (1)

x = 60 - y

Substitute x = 60 - y into (2)

5x + 3.50y = 250

5(60 - y) + 3.50y = 250

300 - 5y + 3.50y = 250

- 5y + 3.50y = 250 - 300

- 1.50y = 50

y = -50/-1.50

y = 33.33

Substitute y = 33.33 into 1

x + y = 60

x + 33.33 = 60

x = 60 - 33.33

x = 26.67 tickets

Number of adults tickets sold = x

= 26.67 tickets

Number of children tickets sold = y = 33.33 tickets

Read the passage.A Flag with 50 StarsThe first American flag to have red and white stripes and white stars on a blue field was flown in 1776, shortly after the United States declared its independence from Great Britain. Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag. There is no evidence that this legend is true, and no one knows for certain who made the first flag, which had 13 stars and 13 stripes. However, we know for a fact that the first flag to have 50 starsthe one we have todaywas designed by a high school student. In 1958, Bob Heft was a 17-year-old student at Lancaster High School in Ohio. At that time, the United States had only 48 states but was on the verge of accepting two more: Alaska and Hawaii. The U.S. flag at the time had six neat rows of eight stars each. What would be the best way to add two more stars while keeping the arrangement neat and orderly? This was the question that Bobs history teacher posed to the class. The teacher gave the students an assignment: design a flag with 50 stars. Bob spent hours in the attic of his house, cutting up a 48-star flag and rearranging the stars until they fit just right. He was pleased with his solution to the problem, but his teacher found it less than perfect and gave him a B minus. Outraged, Bob told his teacher that he was going to send his design to his member of Congress, Walter Moeller. His teacher replied that if Bobs design was accepted as the new flag, he would be more than happy to change the grade to an A. A year later, Bob had graduated and was working as a draftsman when he received a call at work. He never would have imagined a call from President Eisenhowerbut that's who it was! Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag. Bob Heft was invited to Washington, D.C., for a ceremony during which his design was officially adopted as the new flag of the United States.Read the excerpt from A Flag with 50 Stars.
