Answer:

$\frac{16}{25}$

Step-by-step explanation:

Ally gives her sister = 1/5 stickers

Ally gives her cousin = 1/5 of the remainder stickers

Assume Number of sticker Ali has = 1

Remainder after giving stickers to her sister = 1 - 1/5 = 4/5

Number of stickers she gave her sister = $\frac{1}{5}\times\frac{4}{5}$

= $\frac{4}{25}$

Sticker she has = $1-\frac{1}{5}-\frac{4}{25}$

= $\frac{25-5-4}{25}$

= $\frac{16}{25}$

Sticker left with Ally is equal to $\frac{16}{25}$ .

Danny's Bike Shop sells a certain model of racing bike for $550. The same bike can be bought at a competing shop for 7 percent l

AleksAgata [21]

Answer:

$511.5

Step-by-step explanation:

Given: Selling price of bike at Danny´s shop is $550

Bike is sold 7% less at competitor´s shop.

Lets find the discounted amount at Danny´s competitor shop.

∴ $\frac{7}{100} \times 550 = \$ 38.5$

Now, finding the cost of bike at Danny´s competitor.

Cost of bike at Danny´competitor= $(\textrm{Price at dannys shop - discount provided by competitor})$

Cost of bike at Danny´s competitor= $550-38.5= \$511.5$

∴ Cost of bike at Danny´s competitor is $511.5.

the gasoline gauge on a van initially read 1/8 full. When 15 gallons were added to the tank, the gauge read 3/4 full. how many m

nexus9112 [7]

Let x be the capacity of the tank then
3x/4-x/8 =15,
then x=24, so so far it has 3/4 *24 =18 so you need 6 gallons to fill it up

Find the dimensions of a deck which will have railings on only three sides. There is 28 m of railing available and the deck must

Roman55 [17]

Answer:

The largest possible area of the deck is 87.11 m² with dimensions;

Width = 9.33 m

Breadth = 9.33 m

Step-by-step explanation:

The area of a given dimension increases as the dimension covers more equidistant dimension from the center, which gives the quadrilateral with largest dimension being that of a square

Given that the railings will be placed on three sides only and the third side will cornered or left open, such that the given length of railing can be shared into three rather than four to increase the area

The length of the given railing = 28 m

The sides of the formed square area by sharing the railing into three while the fourth side is left open are then equal to 28/3 each

The area of a square of side s = s²

The largest possible area of the deck = (28/3)² = 784/9 = 87.11 m² with dimensions;

Width = 28/3 m = 9.33 m

Breadth = 28/3 m = 9.33 m.

What is the equation of the line AB, if it passes through (-4,0), and is parallel to the line

Karo-lina-s [1.5K]

Rewriting the equation of the given line in slope-intercept form,

$-x-4y=1\\\\-4y=x+1\\\\4y=-x-1\\\\y=-\frac{1}{4}x-\frac{1}{4}$

From this, we know the slope of the given line is -1/4.

Since parallel lines have the same slope, we know the line whose equation we want to find has a slope of -1/4.

Substituting into point-slope form,

$y=-\frac{1}{4}(x+4)\\\\\boxed{y=-\frac{1}{4}x-1}$
