Andres works 20 hours per week at a part-time job. His original pay rate was $10.00 per hour, but he recently received a pay rai

se of x dollars per hour. His new total weekly pay, y, is represented by the equation y=20(10+x).
If Andres earned $210 last week, what was the amount of Andres' raise per hour?

Answer:

X = .5

Step-by-step explanation:

10 × 20 = 200

10.5 × 20 = 210

Explanation:

Y = 210

210 = 20(10+X)

divide both sides by 20

10.5 = 10+X

subtract 10 from both sides

.5 = X

X = .5

Given a polynomial f(x), if (x − 4) is a factor, what else must be true?

ollegr [7]

Answer:

$f(4)=0$

Step-by-step explanation:

<em>The </em><em>Remainder Theorem</em><em> states that when you divide a polynomial $f(x)$ by a linear factor $(x-a)$ , where $a$ is a constant, the remainder is $f(x)$ evaluated at $x=a$ </em>

<em>Moreover, according to the </em><em>Factor Theorem</em><em>, an extension of the Remainder Theorem, if the remainder of the function $f(x)$ is </em><em>0</em><em> when evaluated at $x=a$ , then $(x-a)$ is said to be a factor of the polynomial $f(x)$ </em>

Given the 2 theorems above, it follows that if $(x-4)$ is a factor of $f(x)$ , then the remainder is equal to 0 when $f(x)$ is evaluated at $x=4$

Which means $f(4)=0$

Third answer choice is correct.

Does anyone know the answer?

Alex787 [66]

Answer:

£0.60

Step-by-step explanation:

If each pack costs £1.59 and Nadia orders 15 packs,

then the total order before discount = 1.59 x 15 = £23.85

From the table given, we can see that for an order of £23.85 a 2.5% discount will be applied.

Divide £23.85 by 100 to get 1%: £23.85 ÷ 100 = £0.2385

Now multiply by 2.5 to get 2.5%: £0.2385 × 2.5 = £0.59625 = £0.60

Alternatively, the calculation in one expression is:

(1.59 × 15) × 0.025 = 0.59625

Use the distance formula.

$\sqrt{( x_{2} - x_{1} )^2 + (y_{2} - y_{1})^2}$

Points S and W.
$\sqrt{(3)^2 + (2)^2}$

$\sqrt{9+4}$

$\sqrt{13}$

~3.6

Points S and T
$\sqrt{(3 - 0)^2 + (-2 - 0)^2}$

$\sqrt{(3)^2 + (-2)^2}$

$\sqrt{9+4}$

$\sqrt{13}$

~3.6

Points T and U
$\sqrt{(3 - 2)^2 + (-2 + 5)^2}$

$\sqrt{(1)^2 + (3)^2}$

$\sqrt{1+9}$

$\sqrt{10}$

ahrayia [7]

Step-by-step explanation:

Length of title to board = (1/3) : (1/2) = 2 : 3.

Area of tile to board = (1/3)² : (1:2)² = 4 : 9.
