Find the perimeter and area of the figure

Answer:

Smallest angle of triangle=26 degrees

Second angle of triangle =78 degrees

Third angle of triangle =76 degrees

Step-by-step explanation:

Let x be the smallest angle of triangle

Second angle of triangle=3x

Third angle of triangle=x+50

We know that

Sum of angles of triangle=180 degrees

Using the property

[tex]x+3x+x+50=180[/tex]

[tex]5x=180-50[/tex]

[tex]5x=130[/tex]

[tex]x=\frac{130}{5}[/tex]

[tex]x=26[/tex] degree

Smallest angle of triangle=26 degrees

Second angle of triangle =3(26)=78 degrees

Third angle of triangle =26+50=76 degrees

Answer: 36 hours

Step-by-step explanation:

t = total hours

t = 5d + 8w

t = 5(4) + 8(2)

t = 20 + 16

t = 36

Answer:

140 degrees

Step-by-step explanation:

Ok, so angle in = angle out. This means there are 2 20 degree angles and the total angle of this line is 180 degrees and so 180 - 40 = 140.

Answer:

[tex]x=120[/tex]

Step-by-step explanation:

When two lines are parallel and intersected by a transversal, the alternate corresponding angles are supplementary (their sums equal 180). In the picture, the two parallel lines are intersected by the vertical lines. Then, one of the angles formed intersected again. This means that the sum of the two smaller angles, plus the alternate exterior angle is equal to 180. Hence the following equation can be formed;

[tex]x+20+40=180[/tex]

Simplify,

[tex]x+60=180[/tex]

Inverse operations;

[tex]x+60=180\\-60\\\\x=120[/tex]

Answer:

Step-by-step explanation:

Let the number be aba as it is a palindrome

It divisible by 18, so it is an even number with sum of digits divisible to 9

It is one less than a multiple of 5:

Multiple of 5 will end with 0 or 5, it has to be 5 as a is even, then:

The number 4b4 is divisible by 9 only if b = 1:

So the number is:

Answer:

1 1/2

Step-by-step explanation:

Since x=7 is a vertical line, the slope is undefined. To find an equation that is parallel, the slopes must be equal. Since the slope is undefined, the slope of the parallel line is also undefined. However answer is x=4.

Answer:

B. Add 8 to both sides

Step-by-step explanation:

So you can have 0 at the other end and factor it properly.

Answer:

subtract 13 from both sides

Step-by-step explanation:

subtract 13 so that you will have all of the x's on one side and all of the constant numbers on the other side of the equal sign.

Answer:

6, 2, 2/3, 2/9, 2/27, 2/81

Step-by-step explanation:

The nth term of a geometric progression is expressed as;

Tn  = ar^n-1

a is the first term

n is the number of terms

r is the common ratio

Given

a = 6

r = 1/3

when n = 1

T1 = 6(1/3)^1-1

T1 = 6(1/3)^0

T1 = 6

when n = 2

T2= 6(1/3)^2-1

T2= 6(1/3)^1

T2 = 2

when n = 3

T3 = 6(1/3)^3-1

T3= 6(1/3)^2

T3= 6 * 1/9

T3 = 2/3

when n = 4

T4 = 6(1/3)^4-1

T4= 6(1/3)^3

T4= 6 * 1/27

T4 = 2/9

when n = 5

T5 = 6(1/3)^5-1

T5= 6(1/3)^4

T5= 6 * 1/81

T5 = 2/27

when n = 6

T6 = 6(1/3)^6-1

T6= 6(1/3)^5

T6= 6 * 1/243

T6 = 2/81

Hence the first six terms are 6, 2, 2/3, 2/9, 2/27, 2/81

Answer:

0.074088

Step-by-step explanation:

Let

A:Value of order over $1000

B:Customer pay with credit card

We are given that

Probability of value of order over $1000,P(A)=0.42

If an order is valued at over $1000, then the probability that the customer will pay with a credit card, P(B/A)=0.63

We have to find  the probability that the next three independent orders will each be valued at over $1000

We know that

When two two events A and B are independent then

[tex]P(A\cap B)=P(A)\cdot P(B)[/tex]

Using the formula

The probability that the next three independent orders will each be valued at over $1000=[tex]0.42\times 0.42\times 0.42[/tex]

The probability that the next three independent orders will each be valued at over $1000=0.074088

Answer: x=95 and y=17

Step-by-step explanation:

X-y=78

6y=7+x

6y-7=x

6y-7-y=78

5y-7=78

5y=85

y=17

x-17=78

x=78+17

x=95

Answer:

x=143

y=25

thus ur two numbers are 143 and 25

Answer:

  orchard apples are lower-cost

Step-by-step explanation:

3 pounds is 48 ounces, so the equivalent to the store offering might be about 24 ounces for $4.95/2 ≈ $2.48.

This is substantially less cost per ounce than 25 ounces for $3.79. (24 and 25 are very near, but $2.48 and $3.79 are not.)

Orchard apples are the better deal.

Prove that Dexter is wrong

To prove that Dexter is wrong, we use the following numbers.

[tex]Number = 4[/tex]

The factors are:

[tex]Factor = 1,2\ and\ 4[/tex]

3 factors

Using a greater number:

[tex]Number = 5[/tex]

The factors are:

[tex]Factor = 1\ and\ 5[/tex]

2 factors

From the above analysis:

4 has 3 factors and 5 has 2 factors; which shows that 5 has fewer factors

This shows that Dexter is wrong

Answer:

8 apples for 9.25

Step-by-step explanation:

because 6.25 divided by 5 is 1.25, making each apple $1.25. and 9.25 divided by 8 is rounded to 1.16, making each apple cost $1.16.

Step-by-step explanation:

This is from that site. Visit it and you may find what you're looking for.

If we want to go from point A to point B, getting there through any intermediate point C, which is not on the straight line between A and B, is going to be longer. This should seem intuitively correct. But we will prove it formally.

Where do triangles come into this? Imagine that the line AB is a side of a triangle, ΔABC. Going from A to B is the straight, short way. Going there by first going to another point, C (which is the side AC) and then from C to B (which is the side CB) is going to be longer.
