Answer:

87 years

Step-by-step explanation:

To find the total age 9 years ago you would subtract 9 from Charles's age only, 19. His grandfather is still always going to be 67 years older than he.

19 - 9 = 10

Add 10 and 67 together to find his grandfather's age back then.

10 + 67 = 77

Now add 10 and 77 together.

10 + 77 = 87

The total age 9 years ago was 87 years.

Today: x=19
y=67+19=86

9 years ago: x=19-9=10
y=86-9=77

The total age 9 years ago: x+y=10+77=87

*GEOMETRY*please help me find the surface area of the solid along with the volume of it step by step!
Serjik [45]

Surface area of the solid = 7.1781 in²

Volume of the solid = 0.804 in³

Explanation:

Surface area of the solid = surface area of the square prism - 2(base of the cylinder) + lateral surface of cylinder

surface area of a square prism = 2(lw + lh + wh)

l = length = 1 in

w = length = 1 in

h = height = 1 in

\begin{gathered} \text{Surface area = 2(1}\times1\text{ + 1}\times1\text{ + 1}\times1) \\ \text{Surface area = 2(1 + 1 + 1) = 2(3)} \\ \text{Surface area = 6 in }^2 \end{gathered}

using the value π as it is on the calculator

Base area of a cylinder = πr²

2(Base area of cylinder) = 2πr² = 2π(0.25)² = 0.3927

Lateral surface area = 2πrh = 2π(0.25)(1) = 1.5708

Surface area of the solid = 6 - 0.3927 + 1.5708

Surface area of the solid = 7.178 in²

Volume of the solid = Volume of the square prism - volume of the cylinder

Volume of square prism = length × width × height

length = 1 in, width = 1 in, height = 1 in

Volume of the solid = 1 in × 1 in × 1 in = 1 in³

Volume of a cylinder = πr²h

Volume of the cylinder = π × 0.25 × 0.25 × 1 = 0.196

Volume of the solid = 1 - 0.196

Volume of the solid = 0.804 in³

The first digit may be 1 or 8.

The second digit may be 1, 2, 4, 8.

The third digit may be 1, 3, 5, 7, 9.

There are 2\times4\times5=40\:variants

The probability that this is the correct code is \frac{1}{40}

Please Help me with these question. first person to help me gets brainliest!!!!
lara [203]

4) the distance between the x-values is 3 and the distance between the y-values is 4

3² + 4² = d²

9 + 16 = d²

25 = d²

√25 = d

5 = d

Answer: C

6)

d = \sqrt{(x2 - x1)^{2}  + (y2 - y1)^{2} }

d = \sqrt{(-2 - (-3))^{2}  + (2 - (-4))^{2} }

d = \sqrt{(-2 +3)^{2}  + (2 +4)^{2} }

d =  \sqrt{(1)^{2}  + (6)^{2} }

d =  \sqrt{1 + 36}

d = \sqrt{37}

d = 6.1

Answer: A

Can anyone plz explain the permutation formula in math? and plz make it simple because I'm just a 7th grade student​
mixas84 [53]

Answer:

To calculate permutations, we use the equation nPr, where n is the total number of choices and r is the amount of items being selected. To solve this equation, use the equation nPr = n! / (n - r)!.
