Answer:

265

Step-by-step explanation:

Let t represent the number of tiles needed. Then the area covered by those t tiles will be ...

area = t·0.34 ft²

We want that area to be 90 ft², so we can solve this equation for t:

90 ft² = t·(0.34 ft²)

90 ft²/(0.34 ft²) = t ≈ 264.71

About 265 tiles are needed to cover 90 ft².

What is the solution of the system? y=145-5x and 0.1+0.5x=14.5

Jobisdone [24]

145−5x(0.1)+0.5=14.5
Step 1: Simplify both sides of the equation.
145−5x(0.1)+0.5=14.5
145+−0.5x+0.5=14.5
(−0.5x)+(145+0.5)=14.5(Combine Like Terms)
−0.5x+145.5=14.5
−0.5x+145.5=14.5
Step 2: Subtract 145.5 from both sides.
−0.5x+145.5−145.5=14.5−145.5
−0.5x=−131
Step 3: Divide both sides by -0.5.
−0.5x
−0.5
=
−131
−0.5
x=262

x=262

Simplify the expression x^5 • x^7

iragen [17]

Answer:

$\Huge\boxed{\mathsf{\Rightarrow X^1^2}}$

Step-by-step explanation:

<h3><u>TO SOLVE:</u></h3>

With exponent rule.

<h3><u>SOLUTIONS:</u></h3>

First, use exponent rule.

<u><em>EXPONENT RULE:</em></u>

<u><em /></u>

$\displaystyle \mathsf{\Rightarrow A^B*A^C=A^B^+^C}}$

$\displaystyle \mathsf{X^5^+^7}}$

Solve.

Add the numbers from left to right.

$\displaystyle \mathsf{7+5=\boxed{\mathsf{\Rightarrow 12}}}}$

$\Rightarrow \Large \boxed{\mathsf{X^1^2}}}$

So, the final answer is x¹².

Determine which of the lines, if any, are parallel. Explain.

amid [387]

Answer:

Line A and Line C are parallel

Step-by-step explanation:

<u>Slope Equation: </u> $m=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

<u>Step 1: Find the slope of the first line</u>

Line a passes through (-1, -2) and (1, 0).

$m = \frac{(0- (-2))}{(1 - (-1))}$

$m=\frac{2}{2}$

$m=1$

<u>Step 2: Find the slope of the second line</u>

Line b passes through (4, 2) and (2, -2).

$m = \frac{(-2- 2)}{(2 - 4)}$

$m = \frac{-4}{-2}$

$m=2$

<u>Step 3: Find the slope of the third line.</u>

Line c passes through (0, 2) and (-1, 1).

$m=\frac{(1-2)}{(-1 - 0)}$

$m=\frac{-1}{-1}$

$m=1$

Answer: Line A and Line C are parallel
