Answer: $-\frac{5}{6}$

Step-by-step explanation:

When you multiply fractions, you multiply straight across and simplify.

$-\frac{2}{3}*\frac{5}{4}$ [multiply]

$-\frac{10}{12}$ [simplify]

$-\frac{5}{6}$

Now, we know that the product is $-\frac{5}{6}$ .

Whats the quotient for this?

iren2701 [21]

Answer:

Step-by-step explanation:

Divide 4378 by 15

From 4378 lets take the first two digits for division:

43/ 15

We know that 43 does not come in table of 15

So we will take 15 *2 = 30

43-30 = 13

The quotient is 3 and the remainder is 13

Now take one more number which is 7 with 13

137/15.

Now 137 does not come in table of 15

15*9 = 135

135-137 = 2

It means quotient is 9 and remainder is 2

Now take one more number which is 8 with 2

28/15

28 does not come in table of 15

15*1 = 15

28-15 = 13/15

Now the quotient is 1 and remainder is 13

Hence, the quotient of 4,378 is 291 and remainder is 13 ....

Write the explicit rule of the arithmetic sequence that has a first term of 3 and a fourth term of 18

mr Goodwill [35]

Answer:

$a_{n}$ = 5n - 2

Step-by-step explanation:

The nth term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₄ = 18 , then

a₁ + 3d = 18 , that is

3 + 3d = 18 ( subtract 3 from both sides )

3d = 15 (divide both sides by 3 )

d = 5

Then

$a_{n}$ = 3 + 5(n - 1) = 3 + 5n - 5 = 5n - 2 ← explicit rule

In March, there will be two conferences: one for math and one for history. So far, 7 people have signed up for the math conferen

otez555 [7]

Answer:

After 4 days, the number of people attending both conferences be the same.

Step-by-step explanation:

We are given the following in the question:

Maths conference:

Number of people already signed = 7

Number of people who sign up each day = 2

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$f(x) = 7+2x$

History conference:

Number of people already signed =11

Number of people who sign up each day = 1

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$g(x) =11+x$

Both conference will have same number of people when

$f(x) = g(x)\\\Rightarrow 7 + 2x = 11+x\\\Rightarrow x = 4$

Thus, after 4 days, the number of people attending both conferences be the same.
