Ribbon A is 1/3 m long. It is 2/5 m shorter than Ribbon B. What's the total length of the two ribbons?

Softa [21]

Answer:

$\frac{11}{15}$

Step-by-step explanation:

A = $\frac{1}{3}$

B = $\frac{2}{5}$

A = $\frac{1x5}{3x5}=\frac{5}{15}$

B = $\frac{2x3}{5x3}=\frac{6}{15}$

$\frac{5}{15}$ + $\frac{6}{15}$ = $\frac{11}{15}$

Good Luck!

Need help on this equation its on the paperclip

s344n2d4d5 [400]

Answer:

Blank 1: 1 Blank 2: 8 Blank 3: 72

Step-by-step explanation:

What it is basically saying is that 9*8 is equal to 10*8 - 1*8 [Blank 1]. 10 times any number is a friendly number, it all ends with a 0. The question is saying that it is easier to think of a friendly number and subtracting from that. 10 eights - 9 eights is equal to 1 eight. So we take away 1*8=8 from 10*8=80, or in other words, 80-8 [Blank 2]= 9*8=72 [Blank 3].

The sum of the arithmetic progression 4, ..., 76 is 1920. Find the number of terms and the common difference.

valkas [14]

<u>Number of terms = 48</u>

<u>common difference = 1.5</u>

This question involves the concept of Arithmetic Progression.

The formula for sum of an arithmetic progression series with first and last term given is;

$S_{n}$ = $\frac{n}{2}$ (a + l)

where;

a = first term

l = last term

n = number of terms

From the given sequence, we see that;

first term; a = 4

last term; l = 76

Sum of A.P; $S_{n}$ = 1920

Plugging in relevant values into the sum of an AP formula, we have;

1920 = $\frac{n}{2}$ (4 + 76)

simplifying this gives;

1920 = 40n

n = 1920/40

n = 48

Formula for nth term of an AP is;

$t_{n}$ = $a_{1}$ + (n - 1)d

where;

$a_{1}$ is first term

d is common difference

n is number of term

$t_{n}$ is the nth term in question

the 48th term is 76

Thus;

76 = 4 + (48 - 1)d

76 - 4 = 47d

72 = 47d

d = 72/47

d ≈ 1.5

Thus;

Number of terms = 48

common difference = 1.5
