Answer:

expanded: 7+0.08

standard: 7.08

Step-by-step explanation:

The hundredths place is the second digit after the decimal, so 8 hundredths is 0.08.

Explanation:

Basically a line goes on forever in both directions. A ray only goes off forever in one direction. If we glue together two rays that point in complete opposite directions (eg 1 points north, the other points south) then we form a line.

A line segment is a piece of a line. It doesn't go on forever in either direction. It has 2 endpoints and has a set fixed length. If you know the coordinates of each endpoint, you can use the distance formula to find that length.

When listing all the pairs of factors for a particular term, the factorization process is used.

This process is fundamental in number theory and is used to break down composite numbers into their simplest building blocks: prime numbers.

For example, if we want to find all pairs of factors for the number 24, we could follow these steps:

Start with 1 and the number itself (in this case 24), as these are always factors.

Check if 2 divides 24 evenly. If it does, then 2 and 24/2 (which is 12) are a pair of factors.

Continue this process with increasing numbers. Check 3 (yes, it works, with the pair being 3 and 8), 4 (yes, with the pair being 4 and 6), and so on.

When the numbers you're testing exceed the square root of the original number (approximately 4.9 for 24), you can stop, as you'll have found all pairs.

Step-by-step explanation:

To find out how many pounds of grass seed each lawn got, we need to divide the total amount of grass seed spread by the number of lawns.

First, we need to convert the mixed number 7 1/2 to an improper fraction:

7 1/2 = (2 x 7 + 1)/2 = 15/2

So Green Grass Landscaping spread 15/2 pounds of grass seed.

To find out how many pounds of grass seed each lawn got, we divide the total amount by the number of lawns:

15/2 ÷ 10 = (15/2) ÷ (10/1) = (15/2) x (1/10) = 15/20 = 3/4

Therefore, each lawn received 3/4 of a pound of grass seed.

Answer:

2x + 4x = 130

x = 21.7 feet

Step-by-step explanation:

Width: x

Length: 2x

2x + 2(2x) = 130

6x = 130

x = 130/6

x = 21.7 feet

The joint relative frequency for school children who plan to attend camp and have swimming lesson is 44%.

The correct option to the given question is option d.

We are required to find the joint relative frequency for school children who plan to attend camp and have swimming lessons, rounded to the nearest percent.

To find the joint relative frequency, we use the formula as follows:

Joint relative frequency = frequency of interest / total frequency

Joint relative frequency for school children who plan to attend camp and have swimming lessons = 42 / 96

(As we are looking for the students who plan to attend camp and have swimming lessons, we are interested in the first column of the table and the entry at the intersection of the first row and second column.)

Joint relative frequency for school children who plan to attend camp and have swimming lessons = 0.4375

Joint relative frequency for school children who plan to attend camp and have swimming lessons (rounded to the nearest percent) = 44%(option d).

Answer:

Circle

Step-by-step explanation

The measure of the angle m∠3 of the triangle is m∠3 = 150°

Given data ,

Let the triangle be represented as ΔABC

Now , the measures of the angles are

m∠1 = ( 3x + 12 )°

m∠2 = ( 3x + 18 )°

m∠3 = ( 7x + 10 )°

m∠3 = 180° - ( m∠1  + m∠2 )

Now , for a triangle , the total angles = 180°

So , m∠1 + m∠2 = m∠3

On simplifying , we get

( 3x + 12 ) + ( 3x + 18 ) = ( 7x + 10 )

6x + 30 = 7x + 10

Subtracting 6x on both sides , we get

x + 10 = 30

Subtracting 10 on both sides , we get

x = 20

m∠3 = 150°

Hence , the measure of m∠3 = 150°

Answer:

2.997001

and

3.0301

Step-by-step explanation:

1st Problem

0.999³ - 1 / 0.999 - 1

Calculate 0.999 to the power of 3 and get 0.997002999

0.997002999 - 1 / 0.99 - 1

Subtract 1 from 0.997002999 to get −0.002997001

−0.002997001 / 0.99 - 1

Subtract 1 from 0.999 to get −0.001

−0.002997001/−0.001

Expand  −0.002997001/−0.001 by multiplying both the numerator and the denominator by 1000000000

−2997001/−1000000

Fraction −2997001/−1000000 can be simplified to 2997001/1000000 by removing the negative sign from both the numerator and the denominator, but you will get a positive number either way because when you divide a negative number by another negative number, you get a positive number.

2997001/1000000 = 2.997001

2nd problem

1.01³ - 1 / 1.01 - 1

Calculate 1.01 to the power of 3 and get 1.030301

1.030301 - 1 / 1.01 - 1

Subtract 1 from 1.030301 to get 0.030301

0.030301 / 1.01 - 1

Subtract 1 from 1.01 to get 0.01.

​0.030301/0.01

Expand 0.030301/0.01 by multiplying both numerator and the denominator by 1000000

30301/10000 = 3.0301

Jana, because she has the highest ratio since 56 over 80 is greater than 50 over 80.

The numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.

Given:

In baseball, each time a player attempts to hit the ball, it is recorded.

The ratio of hits compared to total attempts is their batting average.

Each player on the team wants to have the highest batting average to help their team the most.

For the season so far,

Jana has hit the ball 7 times out of 10 attempts.

Tasha has hit the ball 10 times out of 16 attempts.

To find the ratio of batting average:

We must find the same number of attempts.

So,

Jana has ratio 7/10.

So, 56 /80 = 0.7

Tasha has ratio 10/16.

So, 50 / 80 = 0.625

Therefore, Jana has the highest batting average.

Term life insurance has the lower premium because term life insurance pays the face value to your beneficiary if you die within a certain set period of time, whereas whole life insurance covers you your entire life. (Option A)

Insurance is when a third-party (the insurer) promises to indemnify another party (the insured) for losses they might suffer in the future in exchange for agreed upon payments.

Permanent life insurance is a type of insurance that provides a coverage that never expires. The person with a permanent life insurance is covered until he or she passes on. Whole life insurance is a type of permanent life insurance that has a fixed and guaranteed premium and a fixed death benefit.

Term life insurance is a type of insurance that provides coverage to a person only for a scheduled period of time. For example, a person who buys a 10 year term life insurance, the person's insurance only lasts for 10 years. If the person passes on within the 10 years, his beneficiary receives payments. If the person passes on after 10 years, his beneficiary does not receive any payments.
