Olivia uses the work below to determine 55% of 720.

Step 1: 55 percent = 50 percent + 10 percent minus one-half (10 percent)
Step 2: 50% of 720 = 720 divided by 2 = 360
10% of 720 = 720 divided by 10 = 72
One-half (10 percent of 720) = One-half (72) = 31
Step 3: 360 + 72 – 31 = 401

Which explains the error in Olivia’s solution?
Step 1: Olivia used percents that are not equivalent to 55%.
Step 2: Olivia incorrectly determined 50% of 720.
Step 2: Olivia incorrectly determined One-half of 10% of 720.
Step 3: Olivia subtracted One-half of 10% when she should have added.

Jack is age 45 and owns a self-only high deductible health policy with a $7,000 deductible under his HSA. What is his maximum permitted HSA contribution in 2020?

Answers

Answer:

$3350

Step-by-step explanation:

HSA holders have the opportunity to keep a certain amount in reserve up to $3350 for an individual and $6650 for a family. Those that are 55 and older have the opportunity to accumulate an additional $1000 which implies that $4350 per individual and $7650 per family, in which these contributions require 100% tax -deductible at gross income.

Thus, the maximum permitted HSA contribution in 2020 for Jack is $3350.

The maximum permitted HSA contribution in 2020 for jack is $3350.

A health savings account (HSA) is a tax-advantaged savings account a family or individual can use to pay for qualified medical expenses. HSAs are paired with a high-deductible health plan (HDHP) and have annual contribution limits. Each year, the IRS HSA rules adjust the guidelines regarding HDHPs and HSA contribution limits.

HSA holders have the opportunity to keep a certain amount in reserve up to $3350 for an individual and $6650 for a family. Those that are 55 and older have the opportunity to accumulate an additional $1000 which implies that $4350 per individual and $7650 per family.

A dress is on sale for 35% off the regular price. Which expression represents the
price of the dress after the discount? D is to represent the regular price of the
dress after the discount.
A. 0.35d
B. 0.65d
C. 1.35d
D. 1.65d

PLZSSSSSS SHOW YOUR WORK PLZSSSSS

Answers

Answer:  0.65d  (second choice)

====================================================

Explanation:

If you have a 35% discount, this means you save 35% but still pay 65% of the original price.

Notice how 35%+65% = 100%

Or you can think of it as 100% - 35% = 65%

Then we rewrite 65% into 0.65

If d is the original price, then d*0.65 = 0.65d is the price after the discount.

------------------------------

As a slightly longer alternative method, we can say,

d = original price

discount = 35% of d = 0.35d

final price = d - 0.35d

final price = 1d - 0.35d

final price = (1-0.35)d

final price = 0.65d

an=81,d=-3,n=18 solve the question by using formula an=a+(n-1)d

Answers

Step-by-step explanation:

An = A + (n - 1)d

We have An = 81, d = -3 and n = 18.

Hence A = An - (n - 1)d = 81 - (17)(-3) = 132.

Substitute the given values into the equation


81= a+-3{18-1]


Solve the brackets


81= a-3[17]



81= a-51


Move 51 to the other side as a positive number


81+51 is 139


Therefore, a is equal to 139

Step-by-step explanation:

There are nine single digit numbers from integers 1-50 so in order to calculate the probability of getting 3 random numbers from 1-50 to be single digits:

Probability = number of favorable outcomes /total number of outcomes

Therefore Probability of getting 3 single digits randomly from 1-50 = 9/50

A consumer group is investigating the relationship between sugar content and number of calories for different brands of cereal. The equation of the line of best fit for the data is y = 4x + 80, where x is the number of grams of sugar and y is the number of calories in one serving.

What is the meaning of the y-intercept in the line of best fit?

A. Out of all the brands of cereal, the greatest number of calories in one serving was 80.
B. The number of calories in one serving is estimated to be 80 if there is 0 grams of sugar.
C. Out of all the brands of cereal, there were 0 brands of cereal that had 80 calories in one serving.
D. The number of calories in one serving is expected to increase by 80 for each increase in 1 gram of sugar.​

Answers

Answer:

The answer is B

Step-by-step explanation:

B says that 80 grams is what you have if x is 0 which makes more sense than the rest

The statement second states "The number of calories in one serving is estimated to be 80 if there are 0 grams of sugar" option (B) is correct.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

We have:

The equation of the line of best fit for the data:

y = 4x + 80

If we put x = 0 then y:

y = 4(0) + 80

y = 80

This means the number of calories in one serving is estimated to be 80 if there are 0 grams of sugar.

Thus, the statement second states "The number of calories in one serving is estimated to be 80 if there are 0 grams of sugar" option (B) is correct.

You want to know the opinions of dog owners across America on the issue of establishing a law requiring individuals who own pit bulls to obtain insurance for their dogs. You obtain a list of all registered dog owners and mail a survey to a random sample of 5,000 owners. Of those, 2,389 responded and 22% say that they favor the law. Which of the following statements is true?

Because random sampling is used, we can feel confident the percentage of all dog owners who say they favor insurance for pit bulls is close to 22%.

Because less than half of those who were mailed the survey actually responded, we can feel fairly confident that the actual percentage of all dog owners who say they favor pit bull owners getting insurance for their dog is close to 22%.

We cannot trust these results because the survey was mailed. Only survey results from face-to-face interviews are considered valid.

A=A=A, equals \text{m}^2m 2 start text, m, end text, squared

Answers

Answer:

25[tex]\pi\ m^2[/tex]

Step-by-step explanation:

Given that:

A large circle in the park has its middle part painted.

The circle is divided in 4 equal parts.

Radius of the circle = 10 meters

To find:

Area of each section of the circle, [tex]A[/tex] = ?

Solution:

Here, we need to find the area of the bigger circle first and then need to divide it into 4 equal parts to find out the answer.

First of all, let us have a look at the formula for area of a circle with given radius [tex]r[/tex]:

[tex]Area = \pi r^2[/tex]

Here, [tex]r = 10 m[/tex]

Putting the value in the above formula, we get:

So, area = [tex]\pi 10^2 = 100\pi\ m^2[/tex]

Now, there are 4 equal parts of the circle, therefore area of each section will be equal.

Area of each section of the circle:

[tex]\dfrac{100\pi}{4} = \bold{25 \pi}\ m^2[/tex]

O (x.y)- (x+ 3, y-5)
O «.y) - («+3, y + 5)

Answers

Answer:

The rule indicates that the original (x, y) coordinates will be moved to the left by 3 units and up by 5 units.

Thus,

(x, y) ⇒ (x – 3, y + 5)

Step-by-step explanation:

Given the rule T–3, 5(x, y)

The rule indicates that the original (x, y) coordinates will be moved to the left by 3 units and up by 5 units.

It means we need to subtract 3 units from the x-coordinate and add 5 units in the y-coordinate.

Thus, if a triangle on a coordinate plane is translated according to the

rule T-3, s(x, y), then another way to write this rule will be:

If the perimeter of the triangle is 40 cm, find the area of the triangle.

The area of the triangle is, ? cm2.

Answers

Answer:

102 cm²

Step-by-step explanation:

Perimeter is:

P = 40 cmand P = 2x - 4 + 5x - 13 + x + 9 = 8x - 8

Comparing the value:

8x - 8 = 40 8x = 48x = 8 cm

Are formula:

A = 1/2ah

Replacing values:

A = 1/2(x + 9)(2x - 4)A = 1/2(8 + 9)(2*8 - 4) = 1/2*17*12 = 102 cm²

Answer:

60cm²

Step-by-step explanation:

To find :-

The Area of the triangle .

We know that Perimeter is the sum of sides of a triangle. Here the perimeter is 40cm .

→ 2x - 4 +5x - 13 + x + 9 = 40cm .

→ 8x - 8 = 40cm

→ 8x = 40+8 cm

→ 8x = 48 cm

→ x = 6cm .

We know that the area of the triangle is half the product of base and height .

Base = x + 9 = 15cm Height = 2x -4 = 8cm .

→ A = 1/2 × b × h

→ A = 1/2 × 8cm × 15cm

→ A = 60cm²
