Answer:

( $3.19x(4)+1.20y+1.20z$ ) *0.06

Step-by-step explanation:

Cleo buys x packs of markers, y wide-ruled notebooks, and z college-ruled notebooks.

All spiral-bound notebooks, whether wide-ruled or college-ruled, sell for $1.20 each. This gives expressions : 1.20y and 1.20z

A store sells four-packs of permanent markers in assorted colors for $3.19 per pack. Cleo buys x packs of markers so expression becomes :

$3.19x(4)$ (3.19 per pack)

As Cleo buys x packs of markers, y wide-ruled notebooks, and z college-ruled notebooks.

The combined expression becomes:

$3.19x(4)+1.20y+1.20z$

The store charges a 6% sales tax on Cleo’s total bill. So, expression becomes:

( $3.19x(4)+1.20y+1.20z$ ) *0.06

If I can paint 96 sq ft in 15 minutes how long does it take to paint 1 sq ft

White raven [17]

It takes 0.15625 minutes to paint 1 square feet

<em><u>Solution:</u></em>

Given that, I can paint 96 sq ft in 15 minutes

To find: Time taken to paint 1 square feet

From given,

96 square feet is painted in 15 minutes

Let "x" be the time taken to paint 1 square feet

Then, we can say,

96 square feet = 15 minutes

1 square feet = x minutes

This forms a proportion and we can solve the sum by cross multiplying

$96 \times x = 15 \times 1\\\\x = \frac{15}{96}\\\\x = 0.15625$

Thus it takes 0.15625 minutes to paint 1 square feet

Arrange these numbers from least to greatest:

zmey [24]

First let's put them all over 100.
- $\frac{5}{8}$ would change to - $\frac{62.5}{100}$

- $\frac{7}{9}$ to - $\frac{77.7}{100}$

- $\frac{4}{5}$ to - $\frac{80}{100}$

- $\frac{3}{7}$ to - $\frac{42.8}{100}$

Then if we put them from least to greatest it would be from highest to lowest (since they are negatives)

- $\frac{4}{5}$ , - $\frac{7}{9}$ , - $\frac{5}{8}$ , - $\frac{3}{7}$

The answer would be B

Simplify the expression(a4−6a2b2+ b4)−(−2a4+5a2b2+ 3b4) and hence, find its value for a = 2and b = −1.

ELEN [110]

Answer:

(a) $3a^4 - 11a^2b^2 -2b^4$

(b) $3a^4 - 11a^2b^2 -2b^4= 2$

Step-by-step explanation:

Given

$(a^4 - 6a^2b^2+ b^4) - (-2a^4+5a^2b^2+ 3b^4)$

Solving (a): Simplify

$(a^4 - 6a^2b^2+ b^4) - (-2a^4+5a^2b^2+ 3b^4)$

Open brackets

$a^4 - 6a^2b^2+ b^4 +2a^4-5a^2b^2- 3b^4$

Collect Like Terms

$a^4 +2a^4- 6a^2b^2-5a^2b^2+ b^4 - 3b^4$

Simplify Like Terms

$3a^4 - 11a^2b^2 -2b^4$

Solving (b): Simplify when a = 2 and b = -1

$3a^4 - 11a^2b^2 -2b^4$

$3*(2)^4 - 11*(2^2)*(-1)^2 -2*(-1)^4$

$3 * 16 - 11 * 4 * 1 - 2 * 1$

$48 - 44 - 2$

$= 2$

Hence:

$3a^4 - 11a^2b^2 -2b^4= 2$
