Angle CBD is given as 51°

Subtract:

90° - 51° = 39°

Given:

In triangle ABC, m∠A=(8x-2)°, m∠B=(2x-8)° and m∠C=(94-4x)°.

To find:

The sides of the triangle ABC in order from shortest to  longest.

Solution:

In triangle ABC,

[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]              (Angle sum property)

[tex](8x-2)^\circ+(2x-8)^\circ+(94-4x)^\circ=180^\circ[/tex]

[tex](6x+84)^\circ=180^\circ[/tex]

[tex]6x+84=180[/tex]

[tex]6x=180-84[/tex]

[tex]6x=96[/tex]

Divide both sides by 6.

[tex]x=\dfrac{96}{6}[/tex]

[tex]x=16[/tex]

Now,

[tex]m\angle A=(8(16)-2)^\circ[/tex]

[tex]m\angle A=(128-2)^\circ[/tex]

[tex]m\angle A=126^\circ[/tex]

Similarly,

[tex]m\angle B=(2(16)-8)^\circ[/tex]

[tex]m\angle B=(32-8)^\circ[/tex]

[tex]m\angle B=24^\circ[/tex]

And,

[tex]m\angle C=(94-4(16))^\circ[/tex]

[tex]m\angle C=(94-64)^\circ[/tex]

[tex]m\angle C=30^\circ[/tex]

In a triangle the smaller angle has shorter opposite side and larger angle has longer opposite side.

[tex]24^\circ<30^\circ<126^\circ[/tex]

[tex]m\angle B<m\angle C<m\angle A[/tex]

[tex]AC<AB<BC[/tex]

List the sides of triangle ABC in order from shortest to  longest is AC:AB:BC.

Therefore, the correct option is A.

Determine the number of selection

Since there is no condition attached, the number of selection is:

[tex]Selection = ^nC_r[/tex]

Substitute values for n and r

[tex]Selection = ^{12}C_3[/tex]

Apply combination formula

[tex]Selection = \frac{12!}{(12-3)!3!}[/tex]

[tex]Selection = \frac{12!}{9!3!}[/tex]

[tex]Selection = \frac{12*11*10*9!}{9!*3*2*1}[/tex]

[tex]Selection = \frac{12*11*10}{6}[/tex]

[tex]Selection = \frac{1320}{6}[/tex]

[tex]Selection = 220[/tex]

Hence, there are 220 possible ways

Answer:

there are 12 cans

Step-by-step explanation:

6 x 2 =12

Answer:

B

Step-by-step explanation:

Okay, so we know they can run 1/4 a mile in 25 seconds. Now we want to know how far they can run in a minute ( 60 sec.). Because there is 25 seconds in 60 seconds 2.4 times, we multiply 1/4 by 2.4. We get 0.6. We know that there is 60 minutes in an hour, so we multiply 0.6 by 60. Now we know they can run 36 miles in an hour/ 36 miles per hour. So that eliminates C and D.

Anyways, B is correct because if you divide 1/4 by 25 you get 0.01. Multiply that by 60 to get a minute. (Because there is 60 seconds in a minute) Which is 0.6. Then multiply it again by 60 for an hour( because there is 60 minutes in an hour), and you get 36 hours.

Step one: (((x2)+x)+1)+((0-(2x23•x))+5)

Step two: Check for a perfect cube.  2.1    -2x24+x2+x+6  is not a perfect cube.

2.2      Factoring:  -2x24+x2+x+6

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  x+6

Group 2:  -2x24+x2

Pull out from each group separately :

Group 1:   (x+6) • (1)

Group 2:   (2x22-1) • (-x2)

The groups have no common factor and can not be added up to form a multiplication.

So the answer would be,  -2 (x24) + (x2) ++ 6.

Answer:

By opting for the second option, Alice would save $ 15,740.00  in total mortgage cost

Step-by-step explanation:

In order to determine the better of the two options available, we need to determine the total cost under each option as follows:

Option 1:

cost of house=$625,000

loan amount=$625,000-(20%*$625,000)=$500,000

loan amount=monthly payment*(1-(1+r)^-n/r

monthly payment is the unknown

r=monthly interest rate=4%/12=0.33333333%

n=number of monthly payments in 30 years=30*12=360

500,000=monthly payment*(1-(1+0.33333333% )^-360/0.33333333%

500,000=monthly payment*(1-0.301795869 )/0.003333333

500,000=monthly payment*0.698204131 /0.003333333

monthly payment=500,000*0.003333333 /0.698204131

monthly payment=$ 2,387.08  

total monthly payments=$ 2,387.08*360=$859,348.80

Option 2:

upfront fee=$10,000

loan amount=monthly payment*(1-(1+r)^-n/r

monthly payment is the unknown

r=monthly interest rate=3.75%/12=0.3125%

n=number of monthly payments in 30 years=30*12=360

500,000=monthly payment*(1-(1+0.3125%  )^-360/0.3125%

500,000=monthly payment*(1-0.325222459  )/0.003125

500,000=monthly payment*0.674777541  /0.003125  

monthly payment=500,000*0.003125  /0.674777541=$2,315.58  

Total cost=total monthly payments+upfromt fee

total cost=($2,315.58 *360)+$10,000=$843,608.80  

savings by opting for the second option=$859,348.80-$843,608.80  

Answer:

Step-by-step explanation:

ΔSRQ and ΔVTU are similar Triangle.

Triangles are said to be congruent if, under a correspondence, two of a triangle's sides and the angle that connects them are equal to two of another triangle's sides and the angle that connects them.

Given two triangles, ΔRQS and ΔVUT such that,

RS = 16, QR= 64 and VT = 8, UT = 32

If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable.

From the above condition since,

∠R = ∠T

and

[tex]\frac{QR}{SR} = \frac{UT}{VT} = \frac{4}{1}[/tex]

Thus,

ΔSRQ and ΔVTU are similar from the congruency  property of SAS.

Answer:

Step-by-step explanation:

((((((.5 mile = .25 hour<<<<<<<<<<<<<<<<<<<<<<<<<<

Multiply both sides by 4, because there are 4 quarters in 1 hour

(4)(.5) = (.25)(4)

2 miles =1 hr

Multiply both sides of the original equation by 3 to figure out how far in 3/4 of an hour

(3)(.5) = (3)(.25)

1.5 miles = 3/4 of an hour

now add the two answers together to figure out that the person walked 3.5 miles in 1 3/4 hours

***You also could have multiplied both sides of the original equation by 7, recognizing that that there are 7 quarters in 1.75 hours.

Answer:

(a)

A single avocado costs $1

A single tomato costs $0.5

(b)

An avocado costs twice as much as a tomato

Step-by-step explanation:

Represent the tomatoes with T and the avocados with A.

So, we have:

[tex]4T + 8A = 10[/tex] --- (1)

[tex]6T + 14A = 17[/tex] --- (2)

Solving (a): The price of each

Multiply (1) by 1.5

[tex]1.5(4T + 8A = 10)[/tex]

[tex]6T + 12A = 15[/tex] --- (3)

Subtract (3) from (2)

[tex](6T + 14A = 17) - (6T + 12A = 15)[/tex]

[tex]6T - 6T + 14A - 12A = 17 - 15[/tex]

[tex]14A - 12A = 17 - 15[/tex]

[tex]2A = 2[/tex]

Divide both sides by 2

[tex]A = 1[/tex]

Substitute 1 for A in (1)

[tex]4T + 8A = 10[/tex]

[tex]4T + 8(1) = 10[/tex]

[tex]4T + 8 = 10[/tex]

Make 4T the subject

[tex]4T = 10 - 8[/tex]

[tex]4T = 2[/tex]

Divide both sides by 4

[tex]T = \frac{2}{4}[/tex]

[tex]T = 0.5[/tex]

Solving (b): Analysis

In (a), we have:

[tex]T = 0.5[/tex]

[tex]A = 1[/tex]

We can say that an avocado costs twice as much as a tomato

The probability that more than one coin lands heads up is 0.9375.

In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability.

The binomial probability is [tex]^nC_xp^xq^{n-x}[/tex].

Given, Four fair coins are flipped and the number of heads that land face up are counted.

Let, 'p' be the probability of getting a head and 'q' be the probability of getting a tail,

So, p = 1/2 and q= 1/2.

Therefore, The probability that more than one coin lands heads up is,

P(X ≥ 1) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 3).

P(X ≥ 1) = [tex]^4C_1p^1q^3 + ^4C_2p^2q^2 + ^4C_3p^3q^1 + ^4C_4p^4q^0[/tex].

P(X ≥ 1) = [tex]^4C_1(1/2)^1(1/2)^3 + ^4C_2(1/2)^2(1/2)^2 + ^4C_3(1/2)^3(1/2)^1 + ^4C_4(1/2)^4(1/2)^0[/tex].

P(X ≥ 1) = 4(0.5×0.125) + 6(0.25×0.25) + 4(0.125×0.5) + 1(0.0625).

P(X ≥ 1) = 0.25 + 0.375 + 0.25 + 0.0625.

P(X ≥ 1) = 0.9375.

So, The probability of getting one or more heads is 0.9375.
