Answers

Answer:

37.25​, 35.5​, 33.75​, 32, 30.25.

Step-by-step explanation:

Subtract the first term from the second term:

35.5 - 37.25 = -1.75

Subtract the second term from the third term:

35.5 - 33.75 = -1.75

The common difference is -1.75.

To find each subsequent term, add the common difference to the current term.

33.75 + (-1.75) = 32

32 + (-1.75) = 30.25

Answers

Answer:

Hope this helps :)

Step-by-step explanation:

Since the exponent of the scientific notation is positive, move the decimal point 3 places to the right.

The standard notation of the expression is 2 x 10³ is 2000.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

2 x 10³

Standard notation means writing an expression without any base and exponents.

Now,

10³ can be written as 1000.

So,

2 x 10³

= 2 x 1000

= 2000

Thus,

The standard notation is 2000.

In school ,there are 3 girls for every 2 boys . There are 650 students in total . How many students are girls

Answers

Answer:

390 girls.

Step-by-step explanation:

[tex]\frac{3}{5}[/tex] of 650 is 390.

A ratio shows us the number of times a number contains another number. The number of girls in the school will be equal to 260.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

Given that in the school, there are 3 girls for every 2 boys. Therefore, the ratio of girls to boys in the school can be written as,

Ratio = Girls / Boys = 3 / 2

Now, as per the ratio of the girls to boys, we can assume that the number of girls and boys in the school are 3x and 2x, respectively.

Further, given that the total number of students in the school is 650. Therefore, the total number of students can be written as,

Number of boys + Number of girls = 650

3x + 2x = 650

5x = 650

x = 130

Thus, the number of girls in the school can be written as,

Number of girls = 3x

                         = 3 (130)

                         = 260

Hence, the number of girls in the school will be equal to 260.

A large operator of timeshare complexes requires anyone interested in making a purchase to first visit the site of interest. Historical data indicates that 20% of all potential purchasers select a day visit, 50% choose a one-night visit, and 30% opt for a two-night visit. In addition, 10% of day visitors ultimately make a purchase, 40% of one-night visitors buy a unit, and 40% of those visiting for two nights decide to buy. Suppose a visitor is randomly selected and is found to have made a purchase. How likely is it that this person made a day visit

Answers

Answer:

0.143.

Step-by-step explanation:

The first step to take in answering this question is to take or determine the probability in each cases, multiply and sum them up. Therefore, let us delve right into the solution of this problem;

[a]. Historical data indicates that 20% of all potential purchasers select a day visit. Thus, the probability that potential purchasers selects a day visit = 0.20.

[b]. Historical data indicates that 50% choose a one-night visit.  Thus, the probability that potential purchasers selects a one-night visit= 0.50.

[c]. Historical data indicates that 30% of all potential purchasers opt for a two-night visit. Thus, the probability that potential purchasers  opt for a two-night visit = 0.30.

[d].Historical data indicates that 10% of day visitors ultimately make a purchase. Thus, the probability that a day visitors ultimately make a purchase = 0.1.

[e]. The probability for  40% of one-night visitors buy a unit =0.4

[f]. The probability for  40% of two nights decide to buy =0.4.

STEP ONE: Determine the probability that the visitor makes a purchase.

The probability that the visitor makes a purchase = [a] × [d] + [b] × [e] + [c] × [f]. = 0.2 × 0.1 + 0.5 × 0.4 + 0.3 × 0.4 = 0.02 + 0.02 + 0.12 = 0.14.

STEP TWO: Determine How likely is it that this person made a day visit.

0.2 × 0.1/ 0.14 = 0.1428571428571429

find x,y,and z if AB||CD​

Answers

Step-by-step explanation:

Hey there!

75° + 28° + angle KFG = 180°( being linear pair)

103° + angle KFG = 180°

angle KFG = 180° - 103°

Therefore, angle KFG= 77°

Now;

angle KFG + 28° +22° + X= 180°{ co-interior angle}

77°+28° + 22°+x= 180°

X = 180°-127°

Therefore, X = 53°

y == X+22°= 75° { being alternate angle}

angle KFG+x+z = 180° {sum of interior angle of triangle}

77°+53° + z = 180°

z = 180° - 130°

z= 50°

Therefore, X= 53°, y = 75° and z= 50°.

Find the value of x

Answers

Answer:

We know that the area of a triangle is:

1/2 * base * height

We are given:

base = x + 6

height = x

area = 108 m^2

Applying the formula:

Area  = 1/2 * base * height

108 = 1/2 * x * (x + 6)

x² + 6x = 216

x² + 6x - 216 = 0

x² + 18x - 12x -216 = 0   (Splitting the middle term)

x(x + 18) - 12(x + 18) = 0

(x + 18) (x - 12) = 0

Hence, we have 2 possible values for x:   -18 or 12

Since taking x as -18 will result in the length of sides of this triangle to be negative, -18 is NOT the value of x

Therefore, x = 12

so A: 1/5, B: 25% C: 2/7 D: 1.3

so your answer to this question is D

in order to find the biggest decimal you'll have to see which number is bigger in front of the decimal and if there is no number infront look right behind it, D is the greatest because 1.3 is another way of saying 1 whole and 1/3 but besides the point your answer is C

You need a 15% alcohol solution. On hand, you have a 180 mL of a 45% alcohol mixture. How much pure

You will need

mL of the desired 15% solution.
Submit Question

Answers

Let x be the amount of pure water that you use.

The solution you have contains 0.45 • 180 mL = 81 mL of alcohol.

However much water you use, it won't add any alcohol to the solution, so only its total volume changes. Its new volume would be (180 + x) mL. You want the new solution to have a concentration of 15% so that

(81 mL) / ((180 + x) mL) = 0.15

Solve for x :

81 / (180 + x) = 0.15

81 / 0.15 = 180 + x

540 = 180 + x

x = 360

Then the new solution will have a total volume of 180 mL + 360 mL = 540 mL.

So you need to use 360 mL of pure water to get 540 mL of 15% solution.
