What is the answer?????

Answer:

67

Step-by-step explanation:

The number of prime numbers between the whole numbers 60 to 80 is 5 which are 61, 67, 71, 73, and 79.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

A prime number is a positive integer having exactly two factors which are 1 and the number itself. Any number that does not follow this is termed a composite number.

The prime number between 60 and 80 is given below.

Answer:

145°

Step-by-step explanation:

As per the given information: quadrilateral ABCD is a parallelogram.

[tex] m\angle B + m\angle DCB =180\degree \\[/tex]

(adjacent angles of a parallelogram)

[tex] 110\degree + m\angle DCB =180\degree \\

m\angle DCB =180\degree - 110\degree \\

m\angle DCB =70\degree\\

m\angle DCG=\frac{1}{2} m\angle DCB \\(\because GC \: bisects \: \angle DCB) \\

m\angle DCF=\frac{1}{2}\times 70\degree... (\because C-G-F) \\

m\angle DCF=35\degree\\

m\angle BFC = m\angle DCF = 35\degree\\ (Alternate \: \angle s) \\\\

m\angle BFC + m\angle CFA = 180\degree\\ (straight \: line \: \angle s) \\\\

35\degree + m\angle CFA= 180\degree\\

Answer:

1/8

Step-by-step explanation:

7/12= 14/24                                    14/24 + 7/24= 21/24                    

21/24= 7/8           1-7/8= 1/8

The fraction of the total number of puzzle pieces has not been used is 1/8.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Sara and Harry are putting together a puzzle. Sara put together 7/12 of the puzzle pieces. Harry put together 7/24 of the puzzle pieces.

The fraction of the total number of puzzle pieces has not been used is calculated as,

7/12= 14/24      

21/24= 7/8        

1-7/8= 1/8

Answer:

Yes

Step-by-step explanation:

yes

They both have interior angles of 90-51-39, which automatically makes them similar.  You could also see the dilation factor of .75 based on the 2 sides of a right angle to prove it.

 ΔABC and ΔDEF are similar by AA Similarity Theorem.

   Given in the question,

In ΔABC,

In ΔDEF,

To prove these right triangles similar, we can use AA-Similarity Theorem,

By applying triangle sum theorem in ΔDEF,

m∠D + m∠E + m∠F = 180°

m∠D + 90° + 39° = 180°

m∠D = 51°

Hence, ∠D ≅ ∠A and ∠E ≅ ∠B

       Therefore, ΔABC ~ ΔDEF [By AA Similarity Theorem]

The correct answer is:

C) $4269.90.

Explanation:

40 hours per week at 18.32:

40*18.32 = 732.80.

Over time is time and a half; this means:

18.32*1.5=27.48 per hour overtime.

5 hours of overtime per week would be:

27.48*5=137.40.

Together this makes:

732.80+137.40=870.20 per week.

There are 4 weeks in a month;

4*870.20=3480.80.

You make 10% commission on the sales; 10% = 0.1.

0.1*7891=789.10.

Add this to the monthly income:

3480.80+789.10=4269.90.

Answer:

5

Step-by-step explanation:

a+b=30

a=30-b------1

&a-b=20

a=20+b-----2

From eqn 1 and 2, we get

30-b=20+b

or, 10=2b

b=5

Now, a=20+5

a=25

Therefore, a/b=25/5

=5

Using a system of equation, the value of a/b obtained from the values of a and b calculated is 5

The system of equations:

From (1) :

a = 30 - b - - - (3)

Substituting a = 30 - b into (2)

30 - b - b = 20

30 - 2b = 20

30 - 20 = 2b

10 = 2b

b = 5

From (3) :

a = 30 - 5

a = 25

Hence,

a/b = 25 / 5 = 5

Hence, the value of a/b is 5

Answer:

(2, -6)

Step-by-step explanation:

First you want to set both equations equal to each other so you can find one of the variables.

y = x^2 + 3x -4

for second equation lets rearrange so we start with y=

x=y-4

add 4 to both sides

4+x = y or y= x+4

since both equations equal y, lets set them equal to each other

x+4 = x^2 + 3x -4

set it equal to 0 by subtracting x and 4 from both sides

x^2 + 2x -8 = 0

factor

(x+4) (x-2) = 0

so x has to be either -4 or 2. We can shortcut and say only B makes sense since x=2.

to double check, plug in x=2 in both equations

y= 2^2 + 3(2) -4 = 4+6 -4 = 6

2 = y -4; y=6

so B is correct.
