madam [21]

Answer:

$1\dfrac{1}{2}$ teaspoon of salt is required

Step-by-step explanation:

The recipe requires 3/4 cup of flour and Nick wants to make the recipe using 1 cup of flour.

The recipe requires 1 1/8 teaspoon of salt and Nick wants to know how much salt he heeds.

Consider short description:

3/4 cup of flour - 1 cup of flour,

1 1/8 teaspoon of salt - x teaspoon of salt.

Mathematically, you can wrte a proportion:

$\dfrac{\frac{3}{4}}{1\frac{1}{8}}=\dfrac{1}{x}.$

Then

$\dfrac{3}{4}\cdot x=1\cdot 1\dfrac{1}{8},\\ \\\dfrac{3x}{4}=\dfrac{9}{8},\\ \\3x\cdot 8=4\cdot 9,\\ \\24x=36,\\ \\x=\dfrac{36}{24}=\dfrac{3}{2}=1\dfrac{1}{2}.$

zlopas [31]

Answer:

The total cost will be the same for both companies after 20 miles.

Step-by-step explanation:

First, I wrote the equations:

Laguna's Truck Rentals: 2x + 20

Salvatori's truck rentals: 3x

To find when the total cost for both companies will be the same, I kept substituting numbers for the variable until it worked. So, the total cost for both companies will be the same after 20 miles. Hope this helped!

James measured a piece of construction paper to be 6 3/4 inches wide and 9 2/3 inches long. What is the area of the piece of con

ivolga24 [154]

Answer:

The area of the piece of construction paper is $\frac{261}{4} inches^2$

Step-by-step explanation:

Length of construction paper = $6 \frac{3}{4} inches$

= $\frac{27}{4} inches$

Width of construction paper = $9 \frac{2}{3} inches$

= $\frac{29}{3} inches$

Area of construction paper = $Length \times Width$

Area of construction paper = $\frac{27}{4} \times \frac{29}{3}$

= $\frac{261}{4} inches^2$

Hence the area of the piece of construction paper is $\frac{261}{4} inches^2$
