Answer:

  y = 55°

Step-by-step explanation:

You know the sum of angles in a triangle is 180°. So, ...

  25° +30° +x = 180°

And, you know a linear pair of angles totals 180°:

  x + y = 180°

Substituting for 180°, we have ...

  25° +30° +x = x + y

Subtracting x from both sides, we get a relation that is useful to remember:

  25° +30° = y

  y = 55°

_____

This relation is usually described as ...

  An exterior angle is equal to the sum of the remote interior angles.

Lane French had a bad credit rating and went to a local cash center. He took out a $100 loan payable in two weeks at $111.50. What is the percent of interest paid on this loan? (Do not round intermediate calculations. Round your answer to the nearest whole percent.)

Answers

Answer:$15 = 100 x rate x (2/52)

The 2/52 represents 2 weeks out of 52 weeks in a year

So 15/100 = rate x (2/52)

.15 = rate x (2/52)

If you divide by (2/52) on both sides, you get: 3.9 = rate

Don't be fooled by this answer, because it is not in percent form. In order to get it into percent form you need to multiply by 100. So the percent of interest paid on the loan is 390%.

In a lot of these problems you can predict around the percentage before you even do the problem. In this problem, you can tell that the percentage is going to be high because the loan has accrued $15 interest in just two weeks (15% in just two weeks!)

So if there is 15% interest in two weeks, you know it is going to be a very high annual percentage.

Step-by-step explanation:

Dancing Pools sells swimming pools in 4 sizes. The small pool is 72 feet
long and 18 feet wide. The medium pool is 80 feet long and 20 feet wide. The
large pool is 88 by 22. If the new superduper Coffeetable pool is 96 feet long,
how wide will it be?

Answers

Answer:

24 feet wide

Step-by-step explanation:

72/18 = 4

80/20 = 4

88/22 = 4

Since there is one common answer between all sizes, you can make a ratio to help or you can use inverse operations.

Inverse operations is easier, so you would divide 96 by 4, and that will equal 24.

△BCD≅△GEF . If BC=10 , CD=3x+8 and EF=4x+6 , then what is the measure of CD ?

Answers

Given :-

ΔBCD ≅ ΔGEF

Then :-

∠B <=> ∠G ( ∠B = ∠G )

∠C <=> ∠E ( ∠C = ∠E )

∠D <=> ∠F ( ∠ D = ∠F )

BC <=> GE ( BC = GE )

CD <=> EF ( CD = EF )

BD <=> GF ( BD = GF )

Using this let us find CD .

CD = EF

Which means :-

[tex] 3x + 8 = 4x + 6[/tex]

[tex]8 = 4x + 6 - 3x[/tex]

[tex]8 = 1x + 6[/tex]

[tex]1x + 6= 8[/tex]

[tex]1x = 8 - 6[/tex]

[tex]1x = 2[/tex]

[tex]x = 2[/tex]

Then :-

EF =

[tex]EF = 4x + 6 \\ = 4 \times 2 + 6 \\ = 8 + 6 \\ = 14[/tex]

CD =

[tex]CD = 3x + 8 \\ = 3 \times 2 + 8 \\ = 6 + 8 \\ = 14[/tex]

Therefore , CD = 14 .

△BCD≅△GEF

The measure of CD is 14

Given :

Two triangles are congruent

△BCD≅△GEF

When triangles are congruent then the sides are equal

[tex]BC=GE\\CD=EF\\DB=FG\\[/tex]

Given that CD=3x+8 and EF=4x+6

[tex]CD=EF\\3x+8=4x+6\\3x+8-3x=4x-3x+6\\8=x+6\\8-6=x+6-6\\x=2[/tex]

The value of x=2

Now we find measure of CD

[tex]CD=3x+8\\CD=3(2)+8\\CD=14[/tex]

The measure of CD is 14

Step-by-step explanation:

In the past, patrons at a cinema spent an average of $ 2.50 for popcorn with standard deviation of $ 0.90. The amount of these expenditures is normally distributed . Following an intensive public campaign about the negative health effects of eating popcorn by a local medical school, the mean expenditures for a sample of 18 patrons is found to be $ 2.10. At 0.01 level of significance, does this recent experience suggest decline in spending

Answers

Answer:

There's no evidence to show that the recent experience suggests a decline in spending.

Step-by-step explanation:

We are given;

Population mean; μ = $2.5

Population Standard deviation; σ = $0.9

Sample mean; x¯ = $2.1

Sample size; n = 18

Significance level; α = 0.01

Let's define the hypothesis;

Null hypothesis; H0: μ ≥ $2.5

Alternative hypothesis; Ha: μ < $2.5

z-score formula is;

z = (x¯ - μ)/(σ/√n)

z = (2.1 - 2.5)/(0.9/√18)

z = -0.4/0.2121

z = -1.886

Using the p-value from z-score calculator attached and using z = -1.886; α = 0.01; one tail; we have;

P-value = 0.2965

This is more than the significance level. Thus, we will fail to reject the null hypothesis and conclude that there is no evidence to show that the recent experience suggests a decline in spending.

Arsenic blood concentrations in healthy individuals are Normally distributed, with a mean of 3.2 mg/dl and a standard deviation of 1.5 mg/dl. A researcher believes that one area of the United States has naturally elevated arsenic levels in the ground and water supplies. An SRS of 25 individuals in this area found a sample mean arsenic level of 3.75 mg/dl. What are the null and alternative hypotheses for this study?

Answers

Answer:

The null hypothesis                 [tex]H_o : \mu = 3.2 \ mg/dl[/tex]

The alternative hypothesis      [tex]H_a : \mu > 3.2 \ mg/dl[/tex]

Step-by-step explanation:

From the question we are told that

  The mean is  [tex]\mu = 3.2 \ mg/dl[/tex]

   The standard deviation is [tex]\sigma = 1.5 mg/dl[/tex]

   The sample size is  n = 25

    The sample mean is  [tex]\= x = 3.75 \ mg /dl[/tex]

Generally

   The null hypothesis is : That the mean of the  Arsenic blood concentrations in healthy individuals is [tex]\mu = 3.2 \ mg/dl[/tex]

i.e

The null hypothesis  [tex]H_o : \mu = 3.2 \ mg/dl[/tex]

    The alternative hypothesis is : That the mean of the  Arsenic blood concentrations in healthy individuals is greater than  [tex]\mu = 3.2 \ mg/dl[/tex]

What do you mean by Assets?

Anything that will or now has economic worth to a company is considered an asset. Assets are essentially anything that a firm controls and owns that is currently valuable or has the potential to be profitable in the future.

A balance sheet is a financial statement that lists the assets and liabilities of a corporation at a certain point in time. It is one of the three primary financial statements—the other two being the income statement and cash flow statement—that are used to assess a company's performance.

The three forms of balance sheets are: Comparative balance sheets, Vertical balance sheets and Horizontal balance sheets.

Therefore, Value of assets is $15,800 and value of liabilities is $4,400.

Answers

Answer: E) Not enough information

We're given two pairs of congruent sides, and a pair of congruent angles. The angles are not between the two congruent sides. So we don't have enough information to know if the triangles are congruent or not. SSA is not a valid congruence theorem. This is because there are some cases where two triangles are possible leading to ambiguity.

If the marked angles were between the tickmarked sides, then we could use SAS.

Answers

Answer:

The answer is below

Step-by-step explanation:

The height of tank = 12 m = 1200 cm, the diameter of the tank = 8 meters, hence the radius of the tank = 8/2 = 4 m = 400 cm

Let h represent the water level = 8 m = 800 cm. The radius (r) of the water level at a height of 8 m is:

r/h = radius of tank/ height of tank

r/h = 400/1200

r = h/3

12. According to a survey conducted by the American Pet Products Association, 68% of U.S. households own a pet.

Suppose 17% of all U.S. households own a pet and have trouble paying their energy bills. If a U.S. household is randomly sampled, a. What is the probability that the household owns a pet or is having trouble paying energy bills

Answers

Answer:

0.82

Step-by-step explanation:

We are given;

P(households own a pet) = 68% = 0.68

P(have trouble paying their energy bills) = 31% = 0.31

P(households own a pet & have trouble paying energy bills) = 17% = 0.17

Now, to find the probability that a household either owns a pet or having trouble paying energy bills is gotten by the relationship;

P(households own a pet or have trouble paying energy bills) = P(households own a pet) + P(have trouble paying their energy bills) - P(households own a pet & have trouble paying energy bills)

This gives;

P(households own a pet or have trouble paying energy bills) = 0.68 + 0.31 - 0.17 = 0.82

The provided arithmetic sequence adds up to 60.

What is an arithmetic sequence?

The difference between every two successive terms in an arithmetic series is always the same. The number "a" is the first term, and "d" is the common difference between the sequence. The nth term of an arithmetic sequence is given by. aₙ = a + (n – 1)d

Given an arithmetic sequence 12, 14,16,18

The general formula for the Sum of arithmetic sequence:

Sn = n/2 [2a+(n−1)d]

where: n = the number of terms to be added.

a = the first term in the sequence.

d = the constant value between terms.

In our case,

a = 12

n = 4

and d = 14 - 12 = 2

thus

Sum = 4/2(2*12 + (4- 1 )2)

Sum = 2( 24 + 6)

Sum = 60

therefore, the Sum of the given Arithmetic sequence is 60.
