HELP ASAP! AGE PROBLEM!! WILL MARK BRAINLIEST!!!

Mathematics
1 answer:
Gennadij [26K]3 years ago
5 0

Answer:

<u>The present age of the mother is 30 years old</u>

Step-by-step explanation:

Age of Jane = x

Age of Billy = 5x (Billy is five times as old as Jane)

Age of Sara = 15x (Their mother is now three times as old as Billy)

In 2 years Sara will be eight times as old as Jane, therefore:

15x + 2 = 8 (x + 2)

15x + 2 = 8x + 16

15x - 8x = 16 - 2

7x = 14

x = 14/7

x = 2 ⇒ 5x = 10x ⇒ 15x = 30

Jane's present age is 2, Billy's present age is 10 and Sara's present age is 30

<u>The present age of the mother is 30 years old</u>

When Josiah opens and lays a cereal box out flat, he sees that the top and the bottom of the box both measure 2 inches by 8 inch
Dominik [7]

Answer:

<u>252 square inches is the surface area of Josiah's cereal box.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Height of the box = 11 inches

Length of the box = 8 inches

Width of the box = 2 inches

2. What is the surface area of Josiah's cereal box?

Let's recall the surface area of a rectangular prism:

Surface area = 2 (width * length + height * width + length * height)

Surface area = 2 (2 * 8 + 11 * 2 + 8 * 11)

Surface area = 2 (16 + 22 + 88)

Surface area = 2 * 126

<u>Surface area = 252 inches²</u>

PLEASE HELP!!! ILL MARK A HIGH POINT COUNT, GIVE BRAINLIEST, FIVE STARS, AND GIVE THANKS TO WHOEVER ANSWERS CORRECTLY!!!!

Each letter of the alphabet is worth two times as much as the one before it, implying that the value of each letter rises in mathematical progression. The formula for finding the nth term of an arithmetic progression would be used. I am written as

a + (n - 1)d = Tn

Where

The number of terms in the arithmetic sequence is represented by n.

The common difference of the terms in the arithmetic sequence is represented by d.

The first term of the arithmetic sequence is represented by a.

Tn stands for the nth word.

Based on the facts provided,

n = 26 characters1 Equals a

3 minus 1 equals 2 (difference between 2 letters)

Therefore,

1 + (26 - 1)2 = T26

51 = T26

The formula for calculating the sum of an arithmetic sequence's n terms

is as follows:

[2a + (n - 1)d] Sn = n/2

As a result, S26 is the sum of the first 26 terms.

S26 = 20/2[2 1 + (26 - 1)2] S26 = 20/2

[2 + 50] S26 =

676 = S26 = 13 52

Well they painted HALF the room in 3/4 of an hour.

That means that, considering they keep up the same speed, it will take them 3/4 of an hour to do the OTHER half.

This means that it will take them....
