5. The internal dimension of a tank are 14m, 8m and 5m. How much water can be
filled in it. Write the answer in litre. (1m = 100 litre)
​

Answer: the third one

Step-by-step explanation:

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

=h

​

The height of the tent is 2 meters.

Hope this helps :)

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

Answer:

7

Step-by-step explanation:

Here, we want to get the degree of the polynomial

Mathematically, the degree is the power to which the highest power in the polynomial is raised

looking at the polynomial, we can see that the highest power here is raised to the power of 7

that means that the polynomial is of degree 7

Answer:

question 5 is choice c

question 6:

conditional statement:

              if it is a fish then it lives in water

                           true

converse statement:

              if it lives in water it is a fish

                           false

Explanation:

Law of Contrapositives:

The law of contraposition says that a conditional statement is true if, and only if, its contrapositive is true.

that applies to question 5 therefore it is c

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

Answer: x = 13.3

Step-by-step explanation:

Use SOHCAHTOA

The opposite of the angle and the adjacent of the angle is given, so use tangent.

tan(35) = x/19

19*tan(35) = x

x = 13.3

Answer:

Example 1: Y is directly proportional to x. When x = 5, y = 8. What does y equal when x = 9?

First, we set up our general equation. Because y is directly proportional to x, we have:

y = cx

where c is the constant of proportionality. In other words, when x goes up, y goes up, and when x goes down, y goes down.

The next thing we do is plug our values for x and y into the equation so we can solve for c:

8 = (c)(5)

Solving for c, we get c = 8/5 = 1.6 and we plug this into our equation:

y = 1.6x

Now, we can plug x = 9 into the equation to find out what y equals:

y = (1.6)(9)

y = 14.4

So, our answer is 14.4

Example 2: Y is directly proportional to the square of x. When x = 2, y = 32. What does y equal when x = 5?

This time, our general equation is slightly more complicated because x is squared:

y = cx2

Like before, we solve for our constant:

32 = (c)(22)

32 = (c)(4)

We get c = 8:

y = 8x2

Solving for y when x = 5, we get y = (8)(52) = (8)(25) = 200

Example 3: Y is inversely proportional to x. When x = 2, y = 8. What does y equal when x = 24?

This time, because y is inversely proportional to x, our general equation is different:

xy = c

so when x goes up, y goes down, and vise versa. But, other than that, we solve these kinds of problems the same way as direct proportion problems. Solving for the constant, we get:

(2)(8) = c

So c = 16 and our equation is now:

xy = 16

Solving for y when x = 24 we get y = 16/24 = 2/3

Example 4: Y is inversely proportional to the square root of x. When x = 36, y = 2. What does y equal when x = 64?

As before, we set up our equation:

eq001

Since the square root of 36 is 6, it is easy to solve for c:

(6)(2) = c

We get c = 12 and our equation is now:

eq002

Solving for y when x = 64 we get 8y = 12 or y = 12/8 = 1.5 because the square root of 64 is 8.

Answer:

y = 8

Step-by-step explanation:

because y is directly proportional to .√x

=> y = a√x

but when x = 100, y = 80

=> 80 = 10a

=> a = 8

=> y = 8√x

Step-by-step explanation:

Given

[tex]Pea = \$ 3\frac{3}{4}[/tex]

[tex]Corn = \$ 1\frac{1}{2}[/tex]

Required: Determine the total sales

The amount of peas and corns sold are not given. So, I will make some assumptions

If 1 square foot of pea is sold at [tex]\$ 3\frac{3}{4}[/tex], then p square feet will be sold at: [tex]\$ 3\frac{3}{4}p[/tex]

Similarly:

If 1 square foot of corn is sold at [tex]\$ 1\frac{1}{2}[/tex], then c square feet will be sold at: [tex]\$ 1\frac{1}{2}c[/tex]

So, the total is:

[tex]Total = 3\frac{3}{4}p + 1\frac{1}{2}c[/tex]

[tex]Total = \frac{15}{4}p + \frac{3}{2}c[/tex]

Assumptions

[tex]p = 8[/tex]

[tex]c =6[/tex]

The equation becomes:

[tex]Total = \frac{15}{4}*8 + \frac{3}{2}*6[/tex]

[tex]Total = 15 * 2 + 3 * 3[/tex]

[tex]Total = 30+ 9[/tex]

[tex]Total = \$39[/tex]

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]

Answer:

combined means to add so you are going to add anything over 1 because it says longer than 1

1 1/4 has 2 marks so you add 1 1/4 + 1 1/4 =

they have like denominators so you can add them together

1 + 1 = 2 and 1/4 + 1/4 = 2/4 which can be reduced to 1/2

so your answer is 2 1/2
