Answer:

Step-by-step explanation:

The angle shown is 75°. It is less than 90°, so is an acute angle. (The diagram is misleading in that respect.)

__

The two marked angles are vertical angles, so have the same measure.

  3x° = 75°

  x = 25 . . . . . . . . divide both sides by 3°

Answer:

8,9,10

Step-by-step explanation:

Let x be the first integer

x+1 is the next consecutive integer

x+2 is the third consecutive integer

The sum is 27

x + (x+1) + (x+2) = 27

Combine like terms

3x+3 = 27

Subtract 3 from each side

3x+3-3 =27-3

3x =24

Divide by 3

3x/3 = 24/3

x=8

The integers are

x=8

x+1 =9

X+2 =10

Step-by-step explanation:

[tex]B=100e^{0.592t}[/tex]

c) To solve for t, take the natural logarithm of the above equation:

[tex]\dfrac{B}{100}=e^{0.592t}[/tex]

[tex]\Rightarrow \ln \left(\dfrac{B}{100} \right) = \ln e^{(0.592t)}=(0.592t)\ln e[/tex]

Recall that [tex]\ln e = 1[/tex] so we can rewrite the equation above as

[tex]0.592t = \ln \left(\dfrac{B}{100} \right)[/tex]

Finally, solving for t, we get

[tex]t = \frac{1}{0.592} \ln \left(\dfrac{B}{100} \right)[/tex]

Answer:

Both B and C should be correct

Step-by-step explanation:

I'm assuming the x in Expression A is a multiplication symbol. If it is not, please tell me and I will change my answer.

Expression B has the value of 8+4 or 12.

Expression A is 3 times (8+4). You could also say that Expression A is 3 times Expression B.

Since both answer B and C say this, they should both be correct.

Answer:

  C = 9x +2280

Step-by-step explanation:

The 2-point form of the equation for a line can be a place to start.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  C = (4800 -3000)/(280 -80)(x -80) +3000 . . . . . use given values

  C = 1800/200(x -80) +3000 . . . . simplify some

  C = 9x -720 +3000 . . . . eliminate parentheses

  C = 9x +2280

Answer:

b.    x = ±2

Step-by-step explanation:

3x² = 12

Divide both sides by 3

x² = 4

Taske the square root of both sides

x = ±2

Answer:

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

Step-by-step explanation:

m = slope

m = [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]            

m = [tex]\frac{-2-4}{-5-4}[/tex]

m = [tex]\frac{-6}{-9}[/tex]

m = [tex]\frac{6}{9}[/tex]

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

Answer:

First integer = 19

Second integer  = 21

Third integer  = 23

Step-by-step explanation:

To solve this problem, we will need to set up an equation.  

x will be the First integer.  Let  x+2  be the second integer.  x+4  is the third integer.  It all adds up to  63, so your equation is:

(x)+(x+2)+(x+4)=63

Then solve for  x.  

x=19

Answer:

  (9/34)√34 ≈ 1.543

Step-by-step explanation:

The second equation can be rewritten as ...

  6x -10y -12 = 0

  3x -5y -6 = 0

  3x -5y = 6

__

The formula for the distance from point (x, y) to line ax+by+c=0 is ...

  d = |ax+by+c|/√(a²+b²)

Then the distance from a point to the first line is ...

  d = |3x -5y +3|/√(3² +(-5)²)

We know from the rearrangement of the second equation that points on its line satisfy (3x-5y) = 6. Substituting this value for (3x -5y) in the distance formula gives ...

  d = |6 +3|/√34

Simplifying and rationalizing the denominator gives a distance of ...

  d = (9/34)√34 ≈ 1.543

Answer:

$24.20

amount invested = $356

Interest = $44

Step-by-step explanation:

Samia receives a total amount of 400$ for 2 years at 6% per year compound interest, give your answer in 2 decimal places

Simples interest = amount invested x time x interest rate

400 x 0.065 x 1 = $24.20

b. interest = amount received - amount invested

Amount invested = amount received / (1 + r)^n

r = interest rate

n = number of years

400 / (1.06)^2 = 356

Interest = 400 - 356 = $44

Answer:

A.0.0002 inch

Step-by-step explanation:

0.02 inch×1%=0.02 inch×1÷100

=0.0002 inch

If A metal square used in an electronic device must have a thickness of 0.02 inch, with an allowable error of 1 percent, the GREATEST allowable thickness of the metal square is 0.0202 inches. So, correct option is C.

The allowable error for the thickness of the metal square is given as 1 percent. To determine the greatest allowable thickness, we need to find 1 percent of the given thickness and subtract it from the given thickness.

Given thickness: 0.02 inches

1 percent of 0.02 inches = (1/100) * 0.02 inches = 0.0002 inches

Subtracting the 1 percent allowable error from the given thickness:

0.02 inches ± 0.0002 inches = 0.0198 inches or 0.0202 inches

Therefore, the greatest allowable thickness of the metal square is 0.0198 inches or 0.0202 inches.

Among the answer choices provided:

A. 0.0002 inches is the 1 percent allowable error, not the greatest allowable thickness.

B. 0.02 inches is the given thickness.

C. 0.0202 inches is the greatest allowable thickness.

D. 0.03 inches is greater than the greatest allowable thickness.

Hence, the correct answer is C. 0.0202 inches.

Answer:

only 3) is true. EC is equidistant (the same distance) to BD

Step-by-step explanation:

since we have no coordinates or other specific distance information for the various points and lines, we can only confirm statements that must be true for any placement of the lines inside a circle with the described attributes.

the distance EC could be the same as CB, but if we move ED further up or down in the circle (still parallel to CB), we can easily see, that this is not a general case.

the same for CB and BD.

since CB and BD are airways parallel to each other, the symmetry principle of a circle requires that the distance of EC is airways equal to the distance of BD for all such possible pairs of parallel lines inside the circle.

the graph itself gives an example that the distance CB and the distance ED do not have to be the same. they can be for certain pairs of parallel lines in the circle, but not for all of them.

Answer:

A = $3,101.09

A = P + I where

P (principal) = $2,600.00

I (interest) = $501.09

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 3.53/100

r = 0.0353 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 2,600.00(1 + 0.0353/12)(12)(5)

A = 2,600.00(1 + 0.002941667)(60)

A = $3,101.09

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $2,600.00 at a rate of 3.53% per year compounded 12 times per year over 5 years is $3,101.09.

Answer:

Ŷ = -1.7391+0.8913X

Step-by-step explanation:

Given the data :

husband 23,27 ,28,28,29, 30,31,33,35,36

wife 18,20,22,27,21,29,27,29,28,29​

Taking :

Husband as (X)

Wife as (Y)

We could use technology to fit the data and obtain a regression model.

Using technology ; the regression equation obtained is:

Y = -1.7391+0.8913X

Where

Y = wife

X = husband

Slope = 0.8913

Intercept = - 1.7391

Answer:

  46

Step-by-step explanation:

The length of base CD is twice the length of midsegment FG, so you can write the equation ...

  CD = 2×FG

  -3x +52 = 2(13 +5x)

  52 = 26 +13x . . . . . . . . add 3x, simplify

  26 = 13x . . . . . . . . . subtract 26

  2 = x . . . . . . . . . . divide by 13

Then the measure of CD is ...

  CD = -3x +52 = -3(2) +52 = -6 +52

  CD = 46

Answer:

a. 5% of the employees will experience lost-time accidents in both years

b. 24% of the employees will suffer at least one lost-time accident over the two-year period

Step-by-step explanation:

a. What percentage of the employees will experience lost-time accidents in both years?

20% last year, of those who suffered last year, 25% during this year. So

[tex]p = 0.2*0.25 = 0.05[/tex]

5% of the employees will experience lost-time accidents in both years.

b. What percentage of the employees will suffer at least one lost-time accident over the two-year period?

5% during the two years.

10% during the current year. 25% of employees who had lost-time accidents last year will experience a lost-time accident during the current year.

So the 10% is composed of 5% during both years(25% of 20%) and 5% of the 80% who did not suffer during the first year.

First year yes, not on the second.

75% of 20%. So, total:

[tex]0.05 + 0.05*0.8 + 0.75*0.2 = 0.24[/tex]

24% of the employees will suffer at least one lost-time accident over the two-year period
