Suppose that a password consists of 2 letters followed by 4 digits, where there are 26 letters and 10 digits to choose from. How many different passwords are possible?

Answer:

8 1/2

Step-by-step explanation:

Answer:

Step-by-step explanation:

(-5, 2), (5, -1)

(-1 - 2)/(5+5)= -3/10

y - 2 = -3/10(x + 5)

y - 2 = -3/10x - 3/2

y - 4/2 = -3/10x - 3/2

y = -3/10x + 1/2

Answer:

12

Step-by-step explanation:

1:3 multiply them by 4 for 4 juice cans

Answer:

The answer would be A, 12.

Step-by-step explanation:

The ratio of juice to water is 1:3. 1 being the amount of juice, and 3 being the amount of water. If Maria used 4 cans of juice, that makes the new ratio 4:w. W can stand for the amount of water. 1x4=4 so we can multiply 3x4=12.

Answer:

50ft x 3.14 = 157ft

Step-by-step explanation:

It's asking for the circumference.

circumference formula: [tex]C = 2\pi r[/tex]

To give you a better idea of the concept:

To make it simple, in a circle, there is the radius, diameter, and then the circumference.

Radius: The distance half way across the circle (see attachment below).

Diameter: The distance across the circle (see attachment below).

Circumference: The distance around the circle (see attachment below).

As you see, the radius is only half way across, so 2 times the radius would give us the full distance across (diameter).

(But this doesn't matter for this question because it already gave you the diameter (50ft), this was only so I could maybe help you understand the concept a bit more).

Your question:

Alright, it's asking for the circumference; all you have to do is the diameter (50 ft) times pi (3.14).

[tex]50ft *3.14=157ft[/tex]

Step-by-step explanation:

Complete the term and identify the rule

[tex](a)\ 5, 6, 8, [], 15[/tex]

We have:

[tex]5 + 1 = 6[/tex]

[tex]6 + 2 = 8[/tex]

[tex]8 + 3 = 11[/tex] --- Missing term

[tex]11 + 4 = 15[/tex]

The rule is:

Add current term to the position of term

i.e.

[tex]T_{n+1} = T_n + n[/tex]

[tex](b)\ 18, 20, 24, [], 38[/tex]

We have:

[tex]18 + 2*1 = 20[/tex]

[tex]20 + 2*2 = 24[/tex]

[tex]24 + 2 * 3 = 30[/tex] --- Missing term

[tex]30 + 2 * 4 = 38[/tex]

The rule is:

Add current term to twice the position of term

i.e.

[tex]T_{n+1} = T_n + 2 *n[/tex]

[tex](3)\ 14, 17, 20, 23, [][/tex]

We have:

[tex]14 + 3 = 17[/tex]

[tex]17 + 3 =20[/tex]

[tex]20 + 3 = 23[/tex]

[tex]23 + 3 = 26[/tex] --- Missing term

The rule is: Add 3

i.e.

[tex]T_{n+1} = T_n + 3[/tex]

[tex](4)\ 24, 30, 36, 42, [][/tex]

We have:

[tex]24 + 6 = 30[/tex]

[tex]30 + 6 = 36[/tex]

[tex]36 + 6 = 42[/tex]

[tex]42 + 6 = 48[/tex] --- Missing term

The rule is: Add 6

i.e.

[tex]T_{n+1} = T_n + 6[/tex]

[tex](5)\ 1, 10, 100[/tex]

We have:

[tex]10^0 = 1[/tex]

[tex]10^1 = 10[/tex]

[tex]10^2 = 100[/tex]

[tex]10^3 = 1000[/tex] -- Missing term

The rule is: 10 to the power of current position

i.e. [tex]T_n = 10^n[/tex]

Answer:

Therefore, 512/128 simplified to lowest terms is 4/1.

Step-by-step explanation:

Reduce 512/128 to lowest terms

The simplest form of  

512

128

is  

4

1

.

Steps to simplifying fractions

Find the GCD (or HCF) of numerator and denominator

GCD of 512 and 128 is 128

Divide both the numerator and denominator by the GCD

512 ÷ 128

128 ÷ 128

Reduced fraction:  

4

1

Therefore, 512/128 simplified to lowest terms is 4/1.

7.6*7.6=57.76

3.2*3.2=10.24

57.76+10.24=68

square root of 68= 8.2

Answer:

21

Step-by-step explanation:

Add 5.3 + 1.7 and you get 7 (7 is the base of the triangle). Multiply 7 by the height (6) and you get 42. When you put 2 triangles together, it will create a quadrilateral. "Cut the quadrilateral in half" and you will get your triangle's area. The area is 21 :)

Answer:

53.9 square units was my answer, but I learned that it was 21 !

Answer:

D ; 15 cm

Step-by-step explanation:

The graph which matches the distribution of the data is D. This can be known by visually pairing Kristen's data on the y-axis to Eddie's data on the x - axis.

The Numbe rof centimeters Kristen has left to knit when Eddie has 13 cm is about 15 cm. This can be obtained by tracing the poi t 12 upward and tracing its intersection with the best fit line to the y-axis.

Answer:

D ; 15 cm

Step-by-step explanation:

The graph which matches the distribution of the data is D. This can be known by visually pairing Kristen's data on the y-axis to Eddie's data on the x - axis.

The Numbe of centimeters Kristen has left to knit when Eddie has 13 cm is about 15 cm. This can be obtained by tracing the poi t 12 upward and tracing its intersection with the best fit line to the y-axis.

Answer:

m∡A = 41.4°

m∡B = 48.6°

m∡C = 90°

a = 3[tex]\sqrt{7}[/tex]

b = 9

c = 12

Step-by-step explanation:

to find the length of side 'a' I used the Pythagorean Theorem to get:

a² + 9² = 12²

a² + 81 = 144

a² = 63

a = [tex]\sqrt{63}[/tex] which equals [tex]\sqrt{9}[/tex][tex]\sqrt{7}[/tex] which is 3[tex]\sqrt{7}[/tex]

to find m∡B I found the arcsin(B) = 9/12 to get 48.6

to find m∡A I subtracted the sum of 90 + 48.6 from 180°
