One solution.. what you're describing is two lines that intersect at the common y intercept. This will be the only point that satisfies both equations in the system.

Two sides of a right angle triangle is 5 inches each. how long is the third side

ser-zykov [4K]

A= leg/side one= 5
b= leg/side two= 5
c= hypotenuse/side three

Use the Pythagorean Theorem
a^2 + b^2= c^2

5^2 + 5^2= c^2
square each 5

25 + 25= c^2

50= c^2
take square root of both sides

7.07 inches= c

ANSWER: The hypotenuse/third side is 7.07 inches.

Hope this helps! :)

The sides of a hexagon are 2, 3, 2, 4, 7, and 6. Find the perimeter of a similar hexagon with two sides of length 3.

Basile [38]

The first hexagon: 2, 2, 3, 4, 6, 7

The second hexagon: 3, 3, a, b, c, d

The hexagons are similar. Therefore the sides are in proportion.

$\dfrac{a}{3}=\dfrac{3}{2}$ <em>multiply both sides by 3</em>

$a=\dfrac{3}{2}=4.5$

$\dfrac{b}{4}=\dfrac{3}{2}$ <em>multiply both sides by 4</em>

$b=\dfrac{3}{2}\cdot4=6$

$\dfrac{c}{6}=\dfrac{3}{2}$ <em>multiply both sides by 6</em>

$c=\dfrac{3}{2}\cdot6=9$

$\dfrac{d}{7}=\dfrac{3}{2}$ <em>multiply both sides by 7</em>

$d=\dfrac{21}{2}=10.5$

The perimeter:

$P=4.5+6+9+10.5=30$

Monica paid sales tax of $2.80 when she bought a new bike helmet. If the sales tax rate was 7%, how much did the store charge fo

larisa [96]

7 % of cost price is 2.80 , What about 1%?

7 = 2.80

1 = x (where x is the price value of 1% in dollars)

We simplify the above equation, so:

7 × x = 2.8 × 1 → 7x = 2.8 → x = 2.8 / 7 → x = 0.4 dollars

We know that 100% represents the whole price,

so if 1% is 0.4 dollars, then 100% will be 0.4 × 100 = 40 dollars

Therefore the store charged $40 dollars for the helmet before tax
