Jake is selling items for his baseball fundraiser he earns $10 for each mug (x) he sells and $20 for each shirt (y) he sells. He

Anna [14]

Answer:

Step-by-step explanation:

we are given that selling price of each mug(x) is $10

Selling price of each shirt(y) is $20.

Jake wants to earn atleast $250 for his team, So we can write

$(1) 10x+20y\geq 250$

(2) Now the above inequality can be solved for y as follows:

$10x+20y\geq 250\\\text{Add -10x on both the sides}\\10x+20y-10x\geq 250-10x\\20y\geq 250-10x\\\text{Divide both the sides by 20}\\y\geq 12.5-0.5x\\y\geq -0.5x+12.5$

(3)

By the observing the above equation that we just solved for y, we can say that It has an y-intercept of 12.5, and a negative slope of 0.5. Y-intercept of 12.5 means, jake must sell atleast 13 shirts to achieve the target.

Instead of having 1.5 times as many pink flowers as white

elena55 [62]

Answer:

The first row has 4 pink flowers and 2 white flowers

The second row has 6 pink flowers and 3 white flowers

The third row has 8 pink flowers and 4 white flowers.

Step-by-step explanation:

Based on the above question,

Molly has decided to plant a garden with twice as

many pink flowers as white flowers per row.

We can find the number of white flowers in each row by using the principle of ratio to solve this question.

Mathematically, what Molly planted is expressed as:

2 pink flowers : 1 white flower

Therefore for the three rows:

a. The first row is 4 pink flowers

Since, 2 pink flowers : 1 white flower

2 pink flowers = 1 white flower

4 pink flowers = designated as y

We cross multiply

2× y = 4 × 1

Divide both sides by 2

y = 4 ÷ 2

y = 2 white flowers.

Therefore, the first row that Molly planted 4 pink flowers has 2 white flowers.

b. The second row, Molly planted 6 pink flowers

Since, 2 pink flowers : 1 white flower

2 pink flowers = 1 white flower

6 pink flowers = designated as z

We cross multiply

2× z = 6 × 1

Divide both sides by 2

z = 6 ÷ 2

z = 3 white flowers.

Therefore, the second row that Molly planted 6 pink flowers has 3 white flowers.

c. The third row , Molly planted 8 pink flowers

Since, 2 pink flowers : 1 white flower

2 pink flowers = 1 white flower

8 pink flowers = designated as p

We cross multiply

2× p = 4 × 1

Divide both sides by 2

P = 8 ÷ 2

y = 4 white flowers.

Therefore, the third row that Molly planted 8 pink flowers has 4 white flowers.

Therefore, since Molly has decided to plant a garden with twice as

many pink flowers as white flowers per row,

The first row has 4 pink flowers and 2 white flowers

The second row has 6 pink flowers and 3 white flowers

The third row has 8 pink flowers and 4 white flowers.

a volley ball player servers the ball. The ball follows a path given by the equation y=-0.01x^2+0.5x+3 where x and y are measure

dolphi86 [110]

Answer:

(a)

Distance from player should be 13.82 feet or 36.2 feet

(b)

The ball will go over the net

Step-by-step explanation:

we are given

The ball follows a path given by the equation

$y=-0.01x^2+0.5x+3$

where

x and y are measured in feet and the origin is on the court directly below where the player hits the ball

(a)

net height is 8 ft

so, we can set y=8

and then we can solve for x

$8=-0.01x^2+0.5x+3$

$8\cdot \:100=-0.01x^2\cdot \:100+0.5x\cdot \:100+3\cdot \:100$

$800=-x^2+50x+300$

$-x^2+50x-500=0$

$x^2-50x+500=0$

we can use quadratic formula

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$x=\frac{-50\pm \sqrt{50^2-4\left(-1\right)\left(-500\right)}}{2\left(-1\right)}$

$x=5\left(5-\sqrt{5}\right),\:x=5\left(5+\sqrt{5}\right)$

$x=13.82,x=36.2$

So, distance from player should be 13.82 feet or 36.2 feet

(b)

we can plug x=30 and check whether y=8 ft

$y=-0.01(30)^2+0.5(30)+3$

$y=9ft$

we know that

height of net is 8 ft

so, the ball will go over the net

Dafna1 [17]

Answer:

$133.20

Step-by-step explanation:

Since the amount of hours she worked isn't a whole number, we can first separate 18 and 1/2 and work the problem out one at a time.

1. Multiply 7.20 by 18 to get 129.60

2. Multiply 0.50 by 7.20 to get 3.60.

3. Add 129.60 and 3.60 together to get the answer, 133.20.
