To Prove That DEF Congruent DGF By SAS,what Additional Information Is Needed

Answers

Answer 1

Answer:

∠DFE ≅ ∠DFG

Step-by-step explanation:

we know that

Triangles are congruent by SAS, if any pair of corresponding sides and their included angles are equal in both triangles

In this problem we have that

The pair of corresponding sides that are equal are

EF=GF  and DF (is the same side for both triangles)

The included angle are ∠DFE and ∠DFG

therefore

The additional information needed to prove that triangles DEF and DGF are congruent by SAS is that angles ∠DFE and ∠DFG are equal

so

∠DFE ≅ ∠DFG

Lan pays a semiannual premium of ​$650 for automobile​ insurance, a monthly premium of ​$125 for health​ insurance, and an annual premium of ​$450 for life insurance.

The monthly expense is ​$? with explanation

Answers

Answer:

Monthly Expense = $270.83

Step-by-step explanation:

The semi-annual premium is paid twice a year so,

Automobile insurance premium for whole year = 650*2

= $1300

Monthly premium will be paid 12 times a year so,

Health insurance premium for whole year = 125*12 = $1500

Annual premium is only paid once a year.

So adding all the premiums will give us the total premiums for whole year.

Total amount of premium for a year = $1300+$1500+$450

= $3250

The premium amount for whole year is $3250. To find the monthly expense, we will divide it by 12.

So monthly expense is:

= 3250/12

= $270.83 ..

Final answer:

To find the monthly expense, calculate the total annual premium for each insurance and divide by 12. The monthly expense is $187.5.

Explanation:

To find the monthly expense, we need to calculate the total annual premium for each insurance and divide it by 12 (since there are 12 months in a year).

For automobile insurance, the semiannual premium is $650, so the annual premium is $650 * 2 = $1300.

The monthly premium for health insurance is $125.

For life insurance, the annual premium is $450.

Now, let's calculate the total monthly expense: ($1300 + $125 + $450) / 12 = $187.5.

So, the monthly expense is $187.5.

The second angle of a triangular kite is four times as large as the first. The third angle is 55 degrees ° more than the sum of the other two angles. Find the measure of the second angle

Answers

Answer:

50 degrees

Step-by-step explanation:

As the kite is triangular, the sum of all angles will be 180 degrees.

Let x be the first angle.

Then according to the statement second angle is four times as large as the first, second angle will be:

4x

And according to the statement, the third angle is 55 degrees ° more than the sum of the other two angles, third angle will be:

x+4x+55

So,

x+4x+x+4x+55=180

10x+55=180

10x= 180-55

10x=125

x=125/10

x=12.5 degrees

So first angle is 12.5 degrees.

Second angle = 4(12.5)

=50 degrees

Third angle = x+4x+55

= 12.5+50+55

= 117.5 degrees

To check if the sum of angles is 180 degrees

= 12.5+117.5+50 = 180

Hence, second angle is 50 degrees ..

Prove by mathematical induction that 1+2+3+...+n= n(n+1)/2 please can someone help me with this ASAP. Thanks​

Answers

Let

[tex]P(n):\ 1+2+\ldots+n = \dfrac{n(n+1)}{2}[/tex]

In order to prove this by induction, we first need to prove the base case, i.e. prove that P(1) is true:

[tex]P(1):\ 1 = \dfrac{1\cdot 2}{2}=1[/tex]

So, the base case is ok. Now, we need to assume [tex]P(n)[/tex] and prove [tex]P(n+1)[/tex].

[tex]P(n+1)[/tex] states that

[tex]P(n+1):\ 1+2+\ldots+n+(n+1) = \dfrac{(n+1)(n+2)}{2}=\dfrac{n^2+3n+2}{2}[/tex]

Since we're assuming [tex]P(n)[/tex], we can substitute the sum of the first n terms with their expression:

[tex]\underbrace{1+2+\ldots+n}_{P(n)}+n+1 = \dfrac{n(n+1)}{2}+n+1=\dfrac{n(n+1)+2n+2}{2}=\dfrac{n^2+3n+2}{2}[/tex]

Which terminates the proof, since we showed that

[tex]P(n+1):\ 1+2+\ldots+n+(n+1) =\dfrac{n^2+3n+2}{2}[/tex]

5x + 8y =2

4x -6y =9

Answers

Answer:

x = 42/31, y = -37/62

Step-by-step explanation:

5x + 8y =2

4x -6y =9

Multiply the first equation by 4

4(5x + 8y) =2*4

20x +32y = 8

Multiply this equation by -5

-5(4x -6y) =9*-5

-20x +30y = -45

Add them together

20x +32y = 8

-20x +30y = -45

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

62y = -37

Divide by 62

62y/62 = -37/62

Multiply the first equation by 3

3(5x + 8y) =2*3

15x +24y =6

And the second equation by 4

4(4x -6y) =9*4

16x -24y = 36

Add them together

15x +24y =6

16x -24y = 36

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

OA. 5x - 3y = 0
B. -* + 3y = 0
c. 5x - 3y = 0
D. 3x + 5y = 0
E. -3x + 5y = 0

Answers

Answer:

B. 5x + 3y = 0

Step-by-step explanation:

Parallel lines have the same slope.

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points A(-3, 0) and B(-6, 5). Substitute:

[tex]m=\dfrac{5-0}{-6-(-3)}=\dfrac{5}{-3}=-\dfrac{5}{3}[/tex]

The line passes through the origin, therefore the y-intercept is equal to 0.

Therefore we have the equation:

[tex]y=-\dfrac{5}{3}x[/tex]

Convert to the standard form [tex]Ax+By=C[/tex]

[tex]y=-\dfrac{5}{3}x[/tex]         multiply both sides by 3

[tex]3y=-5x[/tex]                add 5x to both sides

[tex]5x+3y=0[/tex]

The equation of the line parallel to AB passing through the origin is 5x - 3y = 0.

The equation of the line that passes through the origin and is parallel to AB is 5x - 3y = 0.

To find the equation of a line parallel to AB passing through the origin, we first need to find the slope of AB, which is (5 - 0) / (-6 + 3) = 5 / -3 = -5/3.

Since the line passing through the origin and parallel to AB has the same slope, its equation will be of the form y = mx. Substituting the point (0, 0) into y = -5/3x gives us y = -5/3x, which simplifies to 5x - 3y = 0.

What is the volume of the cylinder below?

Answers

Answer:

[tex]\large\boxed{D.\ 2160\pi\ units^3}[/tex]

Step-by-step explanation:

[tex]\text{The formula of a volume of a cylinder:}\\\\V=\pi r^2H\\\\r-radius\\\H-height\\\\\text{We have}\ r=12\ \text{and}\ H=15.\ \text{Substitute:}\\\\V=\pi(12^2)(15)=\pi(144)(15)=2160\pi[/tex]

The volume of the cylinder is [tex]\( 2160 \pi \)[/tex] units³.

To find the volume of the cylinder, we'll use the formula for the volume of a cylinder, which is given by:

[tex]\[ V = \pi r^2 h \][/tex]

Where:

- V is the volume of the cylinder,

- r is the radius of the cylinder, and

- h is the height of the cylinder.

Given:

- Height h = 15 units

- Radius r = 12 units

We'll substitute these values into the formula:

[tex]\[ V = \pi \times (12)^2 \times 15 \][/tex]

[tex]\[ V = \pi \times 144 \times 15 \][/tex]

[tex]\[ V = 2160 \pi \][/tex]

So, the volume of the cylinder is [tex]\( 2160 \pi \)[/tex] cubic units.

The correct answer is option D: [tex]\( 2160 \pi \)[/tex] units³.

a. False: ㏒ₐb-㏒ₐc (㏒ₐb / ㏒ₐc) does not exists that property

b. True: (㏒ₐb)-(㏒ₐc) = ㏒ₐ(b/c)  Logarithm of a Quotient

c. False: Does not exists the property:  ㏒ₐ(c+b) = ㏒ₐc + ㏒ₐb

because ㏒₄16 = 2.

d. True:  Logarithm of a Product: ㏒ₐ(c×b) = ㏒ₐc + ㏒ₐb

so

㏒₄(16×5x) = ㏒₄16 + ㏒₄5x = 2 + ㏒₄5x

e. False: Logarithm of a Power: ㏒ₐ(c×b)ⁿ = n ㏒ₐ(c×b) = n (㏒ₐc + ㏒ₐb) = n ㏒ₐc + n ㏒ₐb

so

f(t) + g(t)

f(t) + g(t) =  [1.5t + 50] + [0.1t^2 - 4t + 70]

f(t) + g(t) =  [1.5t + 50+ 0.1t^2 - 4t + 70]

A 52 year-old father has a son and a daughter. The son is twice as old as the daughter. In 4 years the sum of all their ages will be 100. How old are the two siblings now? (RSM problem)

Answers

Answer: son 24 daughter 12

100= total years of age of all ppl in 4years but we want their age now

100=(52+4)+(2x+4)+(x+4)

3x=36

x=12

So daughter is 12 and son is 2x or 24

Any questions on how to set this up or how to arrive at the answer, please feel free to ask. Thanks!

Answer:The age of daughter is 12 years  and age of son is 24 years

Step-by-step explanation:

Given :

Present age of father = 52 years

Let the present age of daughter be x

So according to the question son's age is twice that of daughter's

So present age of son =2x

Now after 4 years the sum of their ages = 100

i.e. x+4 + 2x+4 + 52 +4 =100

3x+ 64 = 100

Subtracting both sides by 64 we get

3x + 64 - 64=100 -64

3x = 36

Dividing LHS and RHS by 3 we get

x=12

i.e. Present age of daughter  = x = 12 years

Present age of son = 2x = 2× 12= 24 years
