1 answer:

8 0

2941526 mi^2
The first thing you should know to solve this problem is the following conversion:
1mi = 1609.34m
Applying the conversion we have:
2941526 * (1609.34 / 1) ^ 2 = 7.61848E + 12 m ^ 2
Answer:
The land area of Australia in square meters is:
7.61848E + 12 m ^ 2

MARKING BRANLIEST!! PLEASE HELP!!! what are the x-intercepts of the quadratic function y=x^2-3x+2

enot [183]

X-intercepts are points where the graph intersects the x-axis, i.e. when y=0.

Substitute y=0 and solve for x:
y=x^2-3x+2
0=x^2-3x+2
0=(x-2)(x-1)

By the zero product property, we deduce x-2=0 or x-1=0, i.e. x=1 or x=2.

Melanie has a piece of cloth 12 and 1/3 yards long. How many 3/4 yard-long pieces can be cut from the cloth?

Harrizon [31]

This is a division problem. First, get 12 1/3 into fraction form instead of mixed number form to make your life easier;
$12 \frac{1}{3} = \frac{36}{3} + \frac{1}{3} = \frac{37}{3} 
$
Now, divide the two fractions. Since this is fraction division, the reciprocal is flipped and the two fractions multiplied.
$\frac{37}{3} * \frac{4}{3} = \frac{148}{9} = 16 \frac{4}{9} 
$
The answer from the fraction division is 16 and four-ninths, but because you need a whole number as an answer,
the answer is 16 pieces.

THE RIGHT ANSWERRRRRR

Mkey [24]

Area of semicircle = 1/2 the area of a circle:
$A_{sc}=\frac{1}{2} \pi r^{2}$
radius is half the diameter of 6ft.
$A_{sc} = \frac{1}{2} \pi (3^{2} )=14.13 ft^{2} .$
Area of the rectangle:
$A_{r} =lw=15*6=90 ft^{2} .$
Add the two together:
90 + 14.13 = 104.13
Round to the nearest tenth (one decimal place)
Area = 104.1 square feet.

Combine like terms to create an equivalent expression.

Brut [27]

Question..

Combine like terms to create an equivalent expression.

½ −⅙q +⅚q - ⅓

Answer:

½ −⅙q +⅚q - ⅓ is equivalent to ⅔q + ⅙

Step-by-step explanation:

Given

½ −⅙q +⅚q - ⅓

Required

Equivalence

½ −⅙q +⅚q - ⅓

We start by collecting like terms.

⅚q - ⅙q + ½ - ⅓

Factorize

(⅚ - ⅙)q + ½ - ⅓

((5 - 1)/6)q + ½ - ⅓

(4/6)q + ½ - ⅓

Reduce 4/6 to lowest term

⅔q + ½ - ⅓

Evaluate fraction

⅔q + (3 - 2)/6

⅔q + ⅙

Hence, ½ −⅙q +⅚q - ⅓ is equivalent to ⅔q + ⅙

The cost to print digital photos at a local store is

snow_tiger [21]

<h2>The cost is same for both the options if we purchase 27 photos</h2>

Step-by-step explanation:

Cost of a photo at a local store is $0.25 per photo. This cost can be modeled to be linear in number of photos as $C_{1}(x)=0.25x$ .

Cost of photos purchased online is $0.15 per photo. However there is a shipping cost of $2.70. This can also be modeled to be linear in number of photos as $C_{2}(x)=2.70+0.15x$ .
