Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 4.5\text{ m}^34.5 m 3 4, point, 5, start text, space, m, end text, cubed. Syrus isn't sure if the tent will be tall enough for him to stand inside.

Answers

Answer:

2 meters

Step-by-step explanation:

Given

[tex]Volume = 4.5m^3[/tex]

The question is incomplete as the picture of the tent is not attached.

However, I will use the attached figure to answer the question.

From the attachment, we have:

[tex]b = 1.5m[/tex] --- base of the tent

[tex]l = 3m[/tex] --- length of the tent

Required

Determine the height of the tent

The volume of the tent is:

[tex]\frac{1}{2} * bhl = Volume[/tex]

Where h is the required height.

So, we have:

[tex]\frac{1}{2} * 1.5 * h * 3 = 4.5[/tex]

[tex]\frac{1}{2} * 1.5 * 3 * h = 4.5[/tex]

[tex]\frac{1}{2} * 4.5 * h = 4.5[/tex]

Make h the subject

[tex]h = \frac{4.5 * 2}{4.5}[/tex]

[tex]h = 2m[/tex]

The height of the tent is 2m

Answer:

2 meters

Step-by-step explanation:

We can use the volume formula, V = 1/2 bhl

⋅1.5⋅h⋅3

=2.25h

The height of the tent is 2 meters.

(urgent please help!!!!)in computing the mean of 8 numbers, a student mistakenly used 17 instead of 25 as one of the numbers and obtained 20 as the mean. find the correct mean.

Answers

i believe the correct mean is 21!

Answer: 21

Step-by-step explanation:

The student's mean of the 8 numbers is 20; the total of the numbers will be

8 x 20 = 160

If we take out the 17 the total will be 160 - 17 = 143

If we then replace the 17 with 25 the total rises to 168.

168 divided by 8 = 21

Mrs. Neville is baking five batches of cookies. She will need 2 \frac{1}{2} 2 1 cups of flour for each batch of cookies. If she begins with a 20 cup bag of flour, what is the resulting change in the amount of flour in the bag?

Answers

Answer:

12.5 cups used

7.5 cups left

Step-by-step explanation:

Number of batches = 5

Cups of flour per batch = 2 1/2 cups

Initial amount of flour = 20 cup bag

After 5 batches ; number of cup used :

5 * 2 1/2 = 12.5 cups of flour

Change in amount of flour in bag :

(20 cups - 12.5 cups) = 7.5 cups

Consider the following equation.

x – 0.32x = 0.68x

Which of the following statements matches the mathematical equations?

Question 5 options:

a) Decrease a number by 0.32 is the same as multiplying by 0.68.

b) Decrease a number by 32% is the same as increasing by 68%.

c) Decrease a number by 0.32 is the same as multiplying by 0.32.

d) Decrease a number by 32% is the same as multiplying by 68%.

Answers

Answer:

d) Decrease a number by 32% is the same as multiplying by 68%

Step-by-step explanation:

Given equation:

x - 0.32x = 0.68x

Options (4 of them given)

a) Decrease a number by 0.32 is the same as multiplying by 0.68.

x - 0.32 = 0.68x ⇒ 0.32x = 0.32Incorrect

b) Decrease a number by 32% is the same as increasing by 68%.

x - 32% = x + 68% ⇒ 0 = 100%Incorrect

c) Decrease a number by 0.32 is the same as multiplying by 0.32.

x - 0.32 = 0.32x ⇒ 0.68x = 0.32Incorrect

d) Decrease a number by 32% is the same as multiplying by 68%

x - 32% = 0.68x ⇒ x - 0.32x = 0.68x ⇒ 0.68x = 0.68xCorrect

"Dan" uses 2/3 cup of brown sugar and 1/4 cup of white sugar to make oatmeal bars. How many cups of sugar does he use in all?

Answers

Answer:

the number of cups of sugar he use in all is [tex]\frac{11}{12}[/tex]

Step-by-step explanation:

The number of cups does he use in all as follows:

= Brown sugar + white sugar

[tex]= \frac{2}{3} + \frac{1}{4}\\\\= \frac{8 + 3}{12} \\\\= \frac{11}{12}[/tex]

Hence, the number of cups of sugar he use in all is [tex]\frac{11}{12}[/tex]
