H(10) is the altitude of a hot air balloon overtime after 10 minutes. In order to find h(10)'s value, you just have to substitute 10 as t in the equation. h(10) and h(t) represents the value of y in a linear equation. So pretty much: h(10)= 210 - 15(10). If calculated correctly, h(10)=60.

Sample response: t represents time, which is the input of the function, so we know that 10 is the time in minutes. h(t) represents the altitude, which is the output of the function after time, t. So, we need to substitute 10 into 210 – 15t in place of t. Simplifying 210 – 15(10), we get  that 60 is the altitude in feet. So, after 10 minutes, the hot air balloon is at 60 feet.

Sammy has a rectangular doormat on her porch. The mat is \dfrac45\text{ m} 5 4 ​ mstart fraction, 4, divided by, 5, end fraction
Otrada [13]

Answer:

Area of the rectangular doormat = 2/5 m²

Step-by-step explanation:

Length of the rectangular doormat = 4/5m

Width of the rectangular doormat = 1/2m

What is the area of the doormat?

Area of a rectangle = length × width

= 4/5m × 1/2m

= (4×1) / (5×2)

= 4 / 10

= 2/5 m²

Area of the rectangular doormat = 2/5 m²

denpristay [2]

Complete question :

A donation center has 44 small bins with 24 caned food in them they wanna give each food bank the same amount of food there are 4 food banks. How many cans should they give to each food bank?

Answer:

264 cans

Step-by-step explanation:

Number of bins = 44

Number of canned food per bin = 24

Total number of canned foods = (number of bins * number of canned food per bin)

Total number of canned foods = 44 * 24 = 1056

Food is to be distributed equally among 4 banks :

Number of food per bank = 1056 / 4 = 264

McGill types 270 words in six minutes his paper is 630 words if he keeps waving at the same rate and how many more minutes when
Delicious77 [7]

Answer:

8 more minutes.

I think the perfect version in your question is:

<em>McGill types 270 words in six minutes his paper is 630 words if he keeps waving at the same rate and how many more minutes when McGill finish typing his paper</em>

Given that:

  • 270 words in six minutes <=> 1 minute = \frac{270}{6} = 45 words
  • His paper is 630 words

So, the total minutes he needs to finish the paper if  he keeps waving at the same rate is:

\frac{The number of words}{Number of words written in one minute}

= \frac{630}{45}

= 14 minutes.

So he needs 14 minutes to finish writing the paper, but he wrote 270 words in 6 minutes already, so it will take him 14-6 = 8 more minutes.

Hope it will find you well!
