Answer 1
1; they are similar cause they both have right angles. 2; the same distance as DE.
Answer 2

Answer:

Yes, they are similar.

[tex]AB\approx 127.3947[/tex]

Step-by-step explanation:

Part 1)

Yes.

First, ∠D and ∠B are both right angles, so they are congruent.

Next, ∠DCE and ∠BCA are vertical angles. So, their measures are congruent.

Then by Angle-Angle Similarity, we acquire:

[tex]\Delta EDC\sim \Delta ABC[/tex]

Part 2)

The corresponding sides of similar triangles are proportional.

Therefore:

[tex]\displaystyle \frac{DE}{DC}=\frac{AB}{BC}[/tex]

By substitution:

[tex]\displaystyle \frac{103}{76}=\frac{AB}{94}[/tex]

Cross-multiply:

[tex]76AB=9682[/tex]

So:

[tex]AB=9682/76\approx127.3947[/tex]

Draw a model to show a 26-pack of candy bars divided equally among 7 people. How
many candy bars will each person have?

Answers

Answer:

[tex]\frac{26}{7}[/tex]

Step-by-step explanation:

Each person will get 3 packs of candy bars

The given parameters are:

Candy bars = 26 pack

People = 7

The number of pack each person will have is then calculated as:

Pack =Candy bars / People

So, we have:

[tex]Pack = \frac{26}{7}[/tex]

Divide 26 by 7 (remove the decimal or fractional parts)

[tex]Pack = 3[/tex]

Hence, each person will get 3 packs of candy bars

An article describes a study in which a new type of ointment was applied to forearms of volunteers to study the rates of absorption into the skin. Eight locations on the forearm were designated for ointment application. The new ointment was applied to five locations, and a control was applied to the other 3. How many different choices were there for the five locations to apply the new ointment

Answers

Answer:

There were 56 different choices for the five locations to apply the new ointment.

Step-by-step explanation:

The order of the locations in which the new ointment was applied is not important. So we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

How many different choices were there for the five locations to apply the new ointment

Five locations from a set of 8. So

[tex]C_{8,5} = \frac{8!}{5!(8-5)!} = 56[/tex]

There were 56 different choices for the five locations to apply the new ointment.

So a whole number answer would be 3 per person with a remainder of 2.

or

It would be a mixed number and be 3 1/2 per person.

Step-by-step explanation:

Well you and your 3 friends are 4 people total.

4 is not a multiple of 14 so if you want to share equally youll have some leftover cause im assuming the answer must be a whole number and not a decimal.

But the most you and your friends can share equally is 3 per person. Since 4 people with 3 packs each (4 x 3) is 12 packs total with 2 packs leftover.

If you want to split these packs among the 4 of you, you can do 4/2 to get 1/2 a pack for each of you guys to share.

So a whole number answer would be 3 per person with a remainder of 2.

or

It would be a mixed number and be 3 1/2 per person.

Lincoln purchased a new car in 2010 for $22,800. The value of the car was $14,100 in the year 2012, then what would be the predicted value of the car in the year 2014, to the nearest dollar?

Answers

Answer:

872

Step-by-step explanation:

The predicted value of $16,348 for the car in 2014.

What is the depreciation rate?

The depreciation rate is the percentage rate at which an asset is depreciated over its projected useful life.

Given,

The car was purchased for $22,800 in 2010.

The value of the car was $14,100 in 2012.

The time elapsed between 2010 and 2012 is 2 years, so we can calculate the annual depreciation rate as follows:

depreciation rate = (purchase price - value after 2 years) / (purchase price x 2 years)

= (22,800 - 14,100) / (22,800 * 2)

= 0.0798 or 7.98%

This means that the car depreciates by approximately 7.98% of its value per year. To predict the value of the car in 2014, we can use this rate to calculate the value after 4 years (since 2010):

value after 4 years = purchase price x (1 - depreciation rate)⁴

= 22,800 x (1 - 0.0798)⁴

≈ 16,347.97

Rounding this to the nearest dollar gives us a predicted value of $16,348 for the car in 2014.

Answer:

c) 6000

Step-by-step explanation:

the car's value would be $6000 because in two years the car decrased by $6000. Divide that by 2, and get $3000. That's how much it decreases in one year. $9000-$3000=$6000

150 into the ratio 4:11

Answers

9514 1404 393

Answer:

  40 : 110

Step-by-step explanation:

There are a number of ways you can go at this. One of my favorite is to consider the value of a "ratio unit." Here, a total of 4+11 = 15 "ratio units" represent the total to be divided: 150. So the value of each one is ...

  150/15 = 10

Then the division is ...

  4 : 11 = 10·4 : 10·11 = 40 : 110

_____

Alternate solution

Let x represent the larger share. Then the ratio is ...

  (150 -x) : x = 4 : 11

Cross-multiplying gives ...

  11(150 -x) = 4x

  1650 = 15x . . . . . add 11x, simplify

  110 = x . . . . . . . . . divide by 15; the larger share

  150-x = 150-110 = 40 . . . . . . the smaller share

The division is 40 : 110.

Answers

Answer:

1/7 ;

0.0034

Step-by-step explanation:

Given that:

X = 1/14, 1/7, 3/14

n = number of observations = 3

Since, probability of X is equally likely ;

P(X) = Σp(x) = 1 ; p(x) = 1/n = 1/3

The mean, m ;

Σx*p(x) = (1/3 * 1/14) + (1/3 * 1/7) + (1/3 * 3/14)

= 1/42 + 1/21 + 3/42

= (1 + 2 + 3) / 42

= 6 / 42

= 1/7

The variance :

Σx²*p(x) - m²

((1/3) * (1/14)^2) + ((1/3) * (1/7)^2) + ((1/3) * (3/14)^2) - (1/7)^2

= 0.0238095 - 0.0204081

= 0.0034014

= 0.0034

Jordan spent 5 hours over the weekend studying for 3 tests. He spent an equal amount of time studying for each test

Answers

Answer:

Option (4)

Step-by-step explanation:

Jordan spent 5 hours studying for 3 test with equal amount of time studying for each test.

On the number line, there are 3 small segments between each number.

Every small segment will represent time = [tex]\frac{1}{3}[/tex] hours

Total number of small segments = 15

If Jordan takes 3 equal durations for the study of each test,

Total number of small segments for each test = [tex]\frac{15}{3}=5[/tex]

Now we can plot these points on the number line.

Further count the segments for the answer ( 1 hour plus 2 small segments)

= 1 + [tex]2\times \frac{1}{3}[/tex]

= [tex]1\frac{2}{3}[/tex]

Therefore, time given for studying each test = [tex]1\frac{2}{3}[/tex] hours

Option (4) will be the answer.
