Emma is taking a trip to the beach. So far, she has driven 58 miles in 1.25 hours.
Determine Emma's constant speed and simplify it to a unit rate.
Then write a linear equation in two variables that represents Emma's distance, d, she travels in any given time t.

Answers

Answer:

46.4miles/hour

d=46.4t

Step-by-step explanation:

Let's say d=at, where d = distance, a = the unit rate, and t = any given time.

We're given that Emma takes 1.25 hours to drive 58 miles. Plugging that into our formula of d=at, we get:

58 = 1.25a.

So, a = 46.4.

The formula now becomes d=46.4t.

A camping store is having a summer sale. Stoves are being sold at 40% off. If the sale price is $57 what was the original price of the stove before the sale

Answers

Answer:

The original price was $142.5.

Step-by-step explanation:

40 ÷ 100 = 0.4

$57 ÷ 0.4 = $142.5

Therefore, $142.5 is our answer.

Answer:

142.5

Step-by-step explanation:

Let's say the original price of the store before the sale is x
so 40% x X = $57
40/100 (X ) =57
0.4 (X) = 57 ====> X = 57 / 0.4 = 142.5

The original price of the stove before the sale is  $ 142.5

Option 3: cos A=15/17

Step-by-step explanation:

Sine is the opposite side over the hypotenuse,

Cosine is the adjacent side over the hypotenuse, and

Tangent is opposite side over the adjacent side

You can remember this with the acronym SOHCAHTOA (sine, opposite, hypotenuse, cosine, adjacent, hypotenuse, tangent, opposite, adjacent)

Option 3 uses cosine, so the adjacent angle to angle A would be 15 and the hypotenuse would be 17, so 15/17

Let length = x

Let width = y

Area = xy

Perimeter equation is

2(x + y) = 356

x + y = 178

Substituting the perimeter equation in the area formula,

Area = x(178 - x)

Area = -x2 + 178x

If the zeros of this quadratic are 0 and 178, then the median is where the maximum area occurs.

178 / 2 = 89

Therefore, the dimensions are

length = 89 feet

width = 178 - 89 = 89 feet

Maximize the enclosed area of the rectangle is 85 ft by 85 ft.

What is perimeter of rectangle?

Perimeter of rectangle is defined as addition the lengths of the rectangle's four sides.

Let length = a

Let width = b

Area of rectangle = ab

Perimeter of rectangle equation is 2(a + b)

2(a + b) = 340

a + b = 170

Substitute the perimeter equation in the area formula,

Area = a(170 - a)

Area = -a² + 170a

If the zeros of this quadratic are 0 and 170, then the median is where the maximum area occurs.

170 / 2 = 85

Therefore, the dimensions are

length = 85 feet

width = 170 - 85 = 85 feet

The rectangle is a square.

The vertices of a triangle MNP are M(5,6) , N(0,3) , and P(4,-2). What is the coordinate of the midpoint of the line connecting the midpoints of sides MN and MP

Answers

Answer:

(3.5, 3.25)

Step-by-step explanation:

Given the vertices of a triangle MNP as M(5,6) , N(0,3) , and P(4,-2).

Midpoint of MP is expressed as;

M(5,6) and P(4,-2).

Xmp = (5+4)/2

Xmp = 9/2

Xmp = 4.5

Ymp = (6-2)/2

Ymp = 4/2

Ymp = 2

Hence the midpoint of MP is at (4.5, 2)

Similarly for MN

M(5,6) , N(0,3)

Xmn = 5+0/2

Xmn = 5/2

Xmn = 2.5

Ymn = 6+3/2

Ymn = 9/2

Ymn = 4.5

Hence the midpoint of MN is (2.5, 4.5)

The coordinate of the midpoint of the line connecting the midpoints of sides MN and MP will be expressed as;

MN(2.5, 4.5) and  MP (4.5, 2)

M = {(2.5+4.5/2, 4.5+2/2)}

M = (7/2, 6.5/2)

M = (3.5, 3.25)

Hence the required midpoint coordinate is (3.5, 3.25)

Mr. Frank has 1.08 kilograms of fertilizer for the plants in his nursery. He wants every plant to get 93 mg of fertilizer 4 times each year. What is the number of plants he could fertilize with that amount? How much fertilizer will he have left over?

Answers

Answer: See explanation

Step-by-step explanation:

First and foremost, we should know that: 1 kilogram = 1,000,000 milligrams

Therefore, 1.08kg will be converted to milligram and this will be:

= 1.08 × 1,000,000 milligrams

= 1,080,000 milligrams

Since every plant gets 93mg of fertilizer, the number of plants that can be fertilized will be:

= 1,080,000 / 93

= 11612.903

Therefore, 11612 plants can be fertilized.

The fertilizer left over will be:

= 1,080,000 - (11612 × 93)

= 1080000mg - 1079916mg

= 84 mg
