Estimate 10/12 − 3/8 using benchmark values. Your equation must show the estimate for each fraction and the final estimate for t

Maksim231197 [3]

Answer: $\frac{11}{24}$

Step-by-step explanation:

Give expression is,

$\frac{10}{12}-\frac{3}{8}$

Since L.C.M ( 12, 8 ) = 24

$=\frac{10\times 2}{12\times 2}-\frac{3\times 3}{8\times 3}$

$=\frac{20}{24}-\frac{9}{24}$

$=\frac{20-9}{24}$

$=\frac{11}{24}$

$\text{Hence, }\frac{10}{12}-\frac{3}{8}=\frac{11}{24}$

Joe is a waiter at a local pizza parlor. he usually gets a tip from the tables he waits on. the bill for one table comes to $34w

Lilit [14]

Answer:

t=p*34

Step-by-step explanation:

t=p*T, where T is the bill for the table Joe waited on, p is the percent tip and t is the tip left for the waiter

In this situation, the bill is 34, so lets plug that in

t=p*34

Find a formula for the given polynomial.

levacccp [35]

In this question, we have to identify the zeros of the polynomial, along with a point, and then we get that the formula for the polynomial is:

$p(x) = -0.5(x^3 - x^2 + 6x)$

------------------------

Equation of a polynomial, according to it's zeros:

Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.

------------------------

Identifying the zeros:

Given the graph, the zeros are the points where the graph crosses the x-axis. In this question, they are:

$x_1 = -2, x_2 = 0, x_3 = 3$

Thus

$p(x) = a(x - x_{1})(x - x_{2})(x-x_3)$

$p(x) = a(x - (-2))(x - 0)(x-3)$

$p(x) = ax(x+2)(x-3)$

$p(x) = ax(x^2 - x + 6)$

$p(x) = a(x^3 - x^2 + 6x)$

------------------------

Leading coefficient:

Passes through point (2,-8), that is, when $x = 2, y = -8$ , which is used to find a. So

$p(x) = a(x^3 - x^2 + 6x)$

$-8 = a(2^3 - 2^2 + 6*2)$

$16a = -8$

$a = -\frac{8}{16} = -0.5$

------------------------

Considering the zeros and the leading coefficient, the formula is:

$p(x) = -0.5(x^3 - x^2 + 6x)$
