In order of operations, do exponents before multiplying.

8 squared= 64

64 x 10=640

Answer:

The total number of votes was 7281 .

Step-by-step explanation:

Let the number of no votes be x

yes : no

5 : 4

4045 : x

4045÷5 = 809

so,

x = 4 × 809 = 3236

3236 people voted no .

Total number of votes = 4045 + 3236

= 7281 ( Ans )

Answer:

a) = 8

b)=243

c)=1 600

d)=321 489

Explanation

a) 2×2= 4×2= 8

b)3×3=9×3=27×3=81×3=243

c)4×4=16×4=64×5=320×5=1 600

d)9×7=63×9=567×9=5 103×7=35 721×9=321 489

Answer:

-8 + 12n

Step-by-step explanation:

First term = a = 4

Common difference = d = second term - first term

                                 = 16 - 4

                                 = 12

Nth term = a + (n -1) *d

              = 4 + (n - 1)*12

              = 4 + n*12 - 1*12

               = 4 + 12n - 12

               = 4 - 12 + 12n

                = -8 + 12n

===============================================

Explanation:

To isolate s, we need to undo the division. We'll multiply both sides by 3

14 = s/3

3*14 = 3*(s/3)

42 = s

s = 42

-------

As a check,

14 = s/3

14 = 42/3 .... replace s with 42

14 = 14

We get the same thing on both sides, so this confirms we have the correct value of s.

Answer:

LN = 4.326

Step-by-step explanation:

dropping a perpendicular from point k to LM

call that point on line LM, point X

angle KLM = 47 degrees so angle NKL = 28 degrees

sin 47 = KX/8.9

KX = 6.509

angle LKX = 90-47-28 = 15 degrees

tan 15 = XN/6.509

XN = 1.744

cos 47 = XL/8.9

XL = 6.070

XL-XN=LN

LN = 6.070-1.744 = 4.326

Step-by-step explanation:

area for square

4×4=16

area for triangle

6×2=12

12÷2=6(the formula for finding a triangle area is height×length after that divided by 2)

for both triangle

6×2=12

after that add 12+16 then you have the answer and don't forget your ²...

Answer:

She has 9 nickels, and 8 dimes.

Step-by-step explanation:

We know that she has a total of $1.25. We know that a nickel is $0.05, and that a dime is $0.10.

9x$0.05=$0.45

8x$0.10=$0.80

Answer:

9 nickels

8 dimes

Step-by-step explanation:

.05(n + 1) + .10n = 1.25

.05n + .05 + .10n = 1.25

.15n = 1.20

n = 1.2 / .15

n = 8

but there are 9 nickels because there is "one more nickel than dimes"

Answer:

45

Step-by-step explanation:

Answer:

Step-by-step explanation:

2, -3 , -8 , -13 , - 18 .............

This is an arithmetic sequence.

First term = a = 2

Common difference = Second term - first term

                                 = -3 - 2 = -5

Nth term = a + (n - 1)*d

               = 2 + (n - 1)*(-5)

               = 2 + n*(-5) - 1 *(-5)

               = 2 - 5n + 5

             = 7 - 5n

n = 19,

19th term = 7 - 5*19

               = 7 - 95

               = - 88

n = 21,

21st term = 7 - 5*21

               = 7 - 105

               = -98

Step-by-step explanation:

- In a right triangle, if ∠B is 45°, then ∠C is too.

-- Since ∠B  and  ∠C  are equal, the sides opposite them

are equal too.  This is an isosceles right triangle.  Its legs

are equal.

-- (The hypotenuse)²  =  (one leg)²  +  (the other leg)²

                                  =       (12-ft)²  +  (12-ft)²

                                  =              (144 x 2)

     The hypotenuse  =  √(144 x 2)  =  12√2 .

Answer:

x = 32.8599

Step-by-step explanation:

you have the hypotenuse and the side adjacent to the angle, so you use

Cos(x) = adjacent/hypotenuse

so

Cos(x) = 21/25

x = cos^-1(21/25)

put this in a calculator:

x = 32.8599 (rounded)

The required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

The area of the circle is given by the pie times square of the radius.

Area of circle = πr^2

Here,
Let the radius of the given circle be r = 5 cm
Area of the circle = πr²

Substitute the value in the above expression,
Area of the circle = π 5²
Area of the circle = 78.5cm²

Thus, the required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

Answer:

C

Step-by-step explanation:

The discriminant informs us about the nature of the zeros

• If b² - 4ac > 0 then 2 real and distinct zeros

• If b² - 4ac = 0 the 2 real and equal zeros

• If b² - 4ac < 0 then zeros are not real

The graph crosses the x- axis at 2 distinct zeros, then

b² - 4ac > 0 , that is positive → C
