Answer: His room's temperature is 20°C.

Step-by-step explanation:

Since we have given that

Temperature at which water boils = 100°C

According to question, it is 400% more than his room's temperature.

Let his room temperature would be 'x'.

So, our equation becomes,

\dfrac{100+400}{100}\times x=100\\\\\dfrac{500}{100}\times x=100\\\\5x=100\\\\x=\dfrac{100}{5}\\\\x=20^\circ C

Hence, his room's temperature is 20°C.

Answer:

20\°C

Step-by-step explanation:

Let

x------> my room's temperature

we know that

400\%=\frac{400}{100}=4

so

The equation that represent this situation is

4x+x=100

Solve for x

5x=100

x=20\°C

Answer:

5. 5.8

6. 6

7. 6

Step-by-step explanation:

5. mean - add all values and divide by the number of values

2 + 4 + 4 + 5 + 5 + 5 + 6 + 6 + 6 + 6 + 7 + 9 + 10 = 75

mean = 75/13 = 5.8

6. median - middle value of values written in ascending order.

2 + 4 + 4 + 5 + 5 + 5 + 6 + 6 + 6 + 6 + 7 + 9 + 10

median = 6

7. mode - value that occurs most times

mode = 6

omeli [17]

Answer:

y = 5x^2+10x +14

Step-by-step explanation:

y = 5(x+1)^2+9

= 5(x^2+2x+1)+9

= 5x^2+10x +14

Acme Company has three identical manufacturing plants, one on the Texas Gulf Coast, one in southern Alabama, and one in Florida.
tino4ka555 [31]

Answer:

Somewhere from $50 million to $100 million

Step-by-step explanation:

Hurricanes usually hit the southernmost states of the USA and considering the fact that all three manufacturing plants are in the southernmost states, it would be reasonable to assume that a single hurricane can wipe out at least one or two since Alabama and Florida are really close to each other and Texas is known to get hurricanes. It usually just depends on where the hurricane occurs.

<h3>Volume:</h3>

With this prism, first separate it into a rectangular prism and a right triangle prism.

First, with the rectangular prism, it would have the units 5 * 5 * 6.3. Then with the right triangle prism, it would take the rest of the remaining space of it, being 3 * 5 * 6.3

The equation for the volume of a rectangular prism is L*W*H and the equation for the volume of a right triangle prism is (L*W*H) / 2.

With this, plug the numbers in for both prisms to get the volume of each of them:

<u>Rectangular prism Volume</u>

5*5*6.3

<em>157.5</em>

<u>Right triangle prism Volume</u>

(3*5*6.3) / 2

94.5 / 2

<em>47.25</em>

Lastly, combine these two values to get the total volume:

157.5 + 47.25 = 204.75 (Round Up) -->

<em><u>204.8 cm^3 = Total Volume </u></em>

<h3>Surface Area:</h3>

Next, with the surface area of the prism. For this, lets combine all of the faces of the prism then add them all up.

First, lets do the bottom of the prism, or the base. It uses the lengths 8 cm and 6.3 cm. Lets do L * W to get the area of this face:

8 * 6.3 = 50.4

Next, lets do the slant side of it, which has the lengths 5.8 and 6.3.

5.8 * 6.3 = 36.54

Then, the top side with the lengths 5cm and 6.3 cm.

5.3 * 6.3 = 33.39

After that, the left side face that opposite to the slantly one:

5 * 6.3 = 31.5

Saving the most tedious part of it for last, the right trapezoids. Luckily, there is an equation for this:

<em>1/2 x (Sum of parallel sides) x (perpendicular distance between the parallel sides).</em>

<em>So, within each of these right </em>trapezoids, there's the parallel sides of 5 and 8. There's also a perpendicular side of 5cm. With this, we can plug this into the equation to solve for this part:

1/2 x (5+8) * (5)

1/2 x (13) * (5)

1/2 x (65)

32.5

Since there's two of them, times this by 2:

32.5 * 2 ---> 65.

Now, with the area of all of the faces, these can be added up for the total surface area:

50.4 + 36.54 + 33.39 + 31.5 + 65 ---> 216.83 (Round Down)-->

<u><em>216.8 cm^2 = Total Surface Area</em></u>

Please explain or show how you got the answer
natka813 [3]
The answer is D) $0.15

James spent: $2.65
On 5 box of markers and 1 erase
So I divided 2.65 by 5 and got .15
$2.65 ÷ 5 = 0.15
So he spent $2.50 on markers an $0.15
Erasers

Based of James, Becky spent a dollar on. 2 boxes of markers
And $0.45 on 3 erasers
