Answer:

A . ( 1 , 2 )

Answer:

9

Step-by-step explanation:

the triangle is right angle.

at right angle it makes 90°. therefore;

(3d+1)°+(6d+8)°=90°

3d+1°+6d+8°=90°

9d+9°=90°.

9d=90°-9°

9d=81°

d=81/9

d=9°

Answer:

40 cm

Step-by-step explanation:

Area of rectangle:

A = bh

A = 5(6)

A = 30

Area of triangle:

A = 0.5bh

A = 0.5(5)(4)

A = 2.5(4)

A = 10

Combined:

30 + 10

40

Step-by-step explanation:

Given :-

And we need to simplify the given numbers . We can use a identity in 1st Question as ,

[tex]\implies (a+b)^2=a^2+b^2+2ab[/tex]

Simplifying first :-

[tex]\implies (\sqrt3+\sqrt2)^2\\\\\implies (\sqrt3)^2+(\sqrt2)^2+2.\sqrt3.\sqrt2 \\\\\implies 3+2+2\sqrt6=\boxed{\red{5+\sqrt6 }}[/tex]

Simplifying second :-

[tex]\implies (3+2)^2\\\\\implies 5^2\\\\\implies \boxed{\red{25}}[/tex]

Answer:

Step-by-step explanation:

the answer is 80

Answer:

38

Step-by-step explanation:

The range of a data set is the smallest number subtracted from the largest number.

[tex]39,41,5,43,26,7,43,24,41[/tex]

In this data set, the largest number is 43 and the smallest number is 5.

[tex]43-5=38[/tex]

Therefore, 38 is the range of this data set.

Answer:

7.7

Step-by-step explanation:

To solve this question we must use Pythagoras (a²+b²=c²) Let those two dots be A and B respectively.Imagine a line is drawn that pases through both dots,

Imagine that the line given is the hypotenuse (the longest side of a right-angled triangle) of a right-angled triangle and the other sides as a line from A going to the right, and a line from B going downwards, making the final vertexes for the triangle at coordinates: 0,-5  4,1 and 4,-5 (the vertex we made). now we find the lengths for the sides: 4 and 6 so we use these to plug them into pythagoras's equation:

4²+6²=c²

24+36=c²

√60=c

c=7.74....

But all we need is until the tenths so the answer is 7.7 (as the hundredths digit, 4, rounds down)

Answer:

$625

$2500

Step-by-step explanation:

tax = percent of tax x income

0.2 x 3125 = 625

amount remaining = income - tax

3125 - 625

Answer:

[tex]2(x - 5) ( 9x - 2)[/tex]

Step-by-step explanation:

((2•3^2x^2) -  94x) +  20

Pull like factors :

  18x^2 - 94x + 20  =   2 • (9x^2 - 47x + 10)

Factor

 9x^2 - 47x + 10

The first term is,  9x^2  its coefficient is  9.

The middle term is,  -47x  its coefficient is  -47.

The last term, "the constant", is  +10

Step-1: Multiply the coefficient of the first term by the constant   9 • 10 = 90

Step-2: Find two factors of  90  whose sum equals the coefficient of the middle term, which is   -47.

     -90    +    -1    =    -91

     -45    +    -2    =    -47

Step-3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -45  and  -2

                    9x^2 - 45x - 2x - 10

Step-4: Add up the first 2 terms, pulling out like factors :

                   9x • (x-5)

             Add up the last 2 terms, pulling out common factors :

                   2 • (x-5)

Step-5: Add up the four terms of step 4 :

                   (9x-2)  •  (x-5)

            Which is the desired factorization

thus the answer is

[tex]2(x - 5) ( 9x - 2)[/tex]

Answer:

Solution given:

18x²-94x+20

taking common

2(9x²-47x+10)

doing middle term factorization

90=45*2

2(9x²-45x-2x+10)

2(9x(x-5)-2(x-5))

2(9x-2)(x-5)

2(x-5)(9x-2)

Last one is a required answer.

find 2 percent of 1000 and times it by 4 the amount of years

Answer:

$1082.43

Step-by-step explanation:

You use the interest formula.

P(1+r/n)^nt

Then plug it in

1000(1+.02)^4

Which comes out to 1082.43

Answer:

2

Step-by-step explanation:

One of them has to be 2. Two odd numbers added together make an even number. So you have two pairs of odd prime numbers and 2 must be the last one. If it is not then the sum will be odd.

Here's an example

3 + 5 + 7 + 11 = 26 which is even. If the next prime is odd, the whole sum will be odd.

26 + 17 = 43

However if the 5th number is two, then the sum of the 5 primes will be even.

26 + 2 = 28

Answer:

Q1 = 4

Q2 = 7

Q3 = 42. 75

Step-by-step explanation:

Given the data:

626676848497

6, 2, 66, 7, 6, 8, 4, 8, 49, 7

Arrange in ascending order :

2, 4, 6, 6, 7, 7, 8, 8, 49, 66

The lower quartile (Q) :

1/4(n+1)th term

n = number of sample = 10

1/4(11)th term

2.75 term : (2 + 6) /2 = 8/2 = 4

Median :

1/2(n+1)th term

n = number of sample = 10

1/2(11)th term

5. 5 term : (7 + 7) /2 = 14/2 = 7

Upper quartile :

3/4(n+1)th term

3/4(11)th term

8.25 th term

3 /4 (8 + 49) = 42.75
