Bryn is riding his bicycle at a constant speed from school to the library. His distance from the library in kilometers x hours a

Vika [28.1K]

Answer:

The distance is 20km

Step-by-step explanation:

Given

$y = 20 - 12x$

Required

The distance between $the\ library\ and\ the$ school

The function represents the distance $y = 20 - 12x$

So, when x = 0.

This implies that he has not started moving.

So:

$y = 20 - 12 * 0$

$y = 20 - 0$

$y = 20$

You have 20 quarters and then find 40% more and then spend 75% how much money do you have left

kirza4 [7]

You have $1.75 left

Step-by-step explanation:

Given,

Number of quarters already have = 20

Percent of quarters found = 40% of already have

Number of quarters found = $\frac{40}{100}*20$

Number of quarters found = $\frac{800}{100}$

Number of quarters found = 8

New total = 20+8 = 28 quarters

Percent of quarters spent = 75%

Number of quarters spent = $\frac{75}{100}*28$

Number of quarters spent = $\frac{2100}{100}$

Number of quarters spent = 21

Quarters left = 28-21 = 7

1 quarter = 25 cents

7 quarters = 25*7 = 175 cents

$1 = 100 cents

175 cents = $\frac{175}{100}=\$1.75$

You have $1.75 left

The triangles are isosceles and ΔABC : ΔJKL. What is the length of J-L?

Tatiana [17]

You know ABC is isoceles, so AB = BC and BC = 2.5 cm.
That means that the scale factor is KL/BC = 2
So JL = 2AC = 8 cm

Evaluate the following expression using the values given.find 2x2 − 2z4 y2 − x2 z4 if x = −4, y = 3, and z = 2.numerical answers

aleksley [76]

To answer the question above, substitute the values of the variables x, y and z given to the equation.
2x² - 2(z^4)y² - x²(z^4)

2(-4)² -2(2^2)(3²) - (-4)²(2^4) = -296

Thus, the numerical answer to the question above is -296.
