Mary and Julie both have a goal of raising $1000 for charity. Mary raises $12 every 4 days. Julie raises $19 every 6 days.

Will Mary or Julie reach her goal first? Explain.

Devin bought a new car
for $19,024 and it was
20% off. Determine the
original price of the car.

Answers

Answer:

$23780

Step-by-step explanation:

Given data

Let the original price be x

discount= 20%

price= $19,024

so that

20/100*x=x-19,024

0.2x= x-19,024

19,024=x-0.2x

19,024=0.8x

x= 19,024/0.8

x=23780

Hence the original price is $23780

My sister is 18 years old. My brother says that his age minus eighteen is equal to my sister's age. How old
is my brother?
Enter an equation, using b as your variable, to find how old my brother is.
The equation is
My brother is
years old.

Answers

Answer:

The brother is 36 years old.

Step-by-step explanation:

b = brothers age

b - 18 = 18 | Given

b = 36 | Add 18 to both sides to cancel out -18 and get his age.

Answer:

36 years old or b-18 = 18

Step-by-step explanation:

Since there is an 18 year difference between the brother and the sister, all you have to do is subtract 18 from how hold the brother is. Since we know that the age of the sister is 18, the equation needs to be equal to 18. Using this, we know the equation is b - 18 = 18. When we add 18 to both sides we get that b=36.

Together, teammates Pedro and Ricky got 2680 base hits last season. Pedro had 276 more hits than Ricky. How many hits did each player have?

Answers

Answer:

Ricky it is 1,202

And for Pedro = 1,202 + 276 = 1,478

Step-by-step explanation:

The computation is shown below:

Let us assume the ricky be x

So pedro be x + 276

Now the equation is

x + x + 276 = 2680

2x + 276 = 2680

2x = 2680 - 276

2x = 2404

x = 1,202

For Ricky it is 1,202

And for Pedro = 1,202 + 276 = 1,478

Find the area of the shape below, giving your answer to 1 decimal place.
10 cm
15 cm

Answers

Answer:

≈ 189.3 cm²

Step-by-step explanation:

The shape is composed of a rectangle and a semicircle, then

area of rectangle = 15 × 10 = 150 cm²

The semicircle has a diameter of 10 cm , so radius = 10 ÷ 2 = 5 cm

area of semicircle = [tex]\frac{1}{2}[/tex] πr² = 0.5 × π × 5² = 12.5π cm²

area of shape = 150 + 12.5π ≈ 189.3 cm² ( to 1 dec. place )

Answers

Answer:

y = 2x - 9

Step-by-step explanation:

Use slope intercept form, y = mx + b

Plug in the slope, x, and y, then solve for b:

y = mx + b

1 = 2(5) + b

1 = 10 + b

-9 = b

Then, plug in b and the slope into y = mx + b

y = mx + b

y = 2x - 9

So, the equation of the line is y = 2x - 9

Answer:

Step-by-step explanation:

y=mx+b, m=2

y=2x+b, using point (5,1)

1=2(5)+b

b=-9

y=2x-9

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 – 160x + 300. The variable x is the number of televisions sold.

If 150 televisions are sold, what is the profit?

$2,700
$6,000
$50,700
$51,300

Answers

Answer: $50,700 is the profit

If 150 televisions are sold, the profit is $50,700.

What is profit?

Profit is the total revenue less the total cost.

Profit = total revenue - total cost

What is profit?

Profit = (3x^2 + 180x) - (3x2 – 160x + 300)

Profit = (3 x 150^2 + 180 x 150) - (3 x 150^2 - 160x 150 + 300)

27,000 + 24,000 - 300

Profit = $50,700

A national park has two types of bears: Grizzly bears and black bears. A sciantist has reported 9 out of 12 bears she tagged are black bears. Show a model that compares the number of black bears tagged to the number of grizzly bear?

Answers

Answer:

Z = 0.75x + 0.25y

Step-by-step explanation:

Two bear types are identified :

Black bears and Grizzly bears

9 out of 12 = black bears ; Hence, 3 are grizzled

For the model:

For a bear population of Number x

Total bear population = black bear, x + grizzled bear, y

Proportion of black bear = 9/ 12 = 0.75

Grizzled bear = 1 - 0.75 = 0.25

Total bear population , Z= 0.75x + 0.25y

Hence,

Z = 0.75x + 0.25y
