Answer:

Books should be kept in second box.

Step-by-step explanation:

If the sum of all the weight of all books is between 4 and 6 pounds then it should be kept in first box

If the sum of all the weight of all books is between 5 and 7 pounds then it should be kept in second box

If the sum of all the weight of all books is between 8 and 9 pounds then it should be kept in first box .

Here sum of the weighs of all the books = 3.1lb+2.4lb +0.75lb

= 6.25 lb

Here we can see that 6.25 lb lies between 5 and 7 which is the weigh limit

for the second box

therefore we can keep the books in second box.

A pair of equations is shown below:

horrorfan [7]

Answer:

A. x=2, y = 7.

B. (2, 7).

Step-by-step explanation:

A. You can eliminate y by subtracting the equations:

y = 8x - 9

y = 4x - 1 Subtract:

0 = 4x - 8

4x = 8

x = 8/4 = 2.

Now substitute for x in the first equation:

y = 8(2) - 9 = 7.

Check in the second equation:

y = 4x - 1

7 = 4(2) - 1 = 7. Check is OK.

B. On the graph they will intersect at the point (2, 7).

They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.

Find the area of the triangle with the given base and height. b = 3 m and h = 10 1/2 m

svetoff [14.1K]

Statement:

The base of a triangle is 3m and its height is $10 \frac{1}{2}$ m.

To find out:

The area of the triangle.

Solution:

Given, base = 3m, height = $10 \frac{1}{2}$ m
We know,

$\sf \: area \: \: of \: \: a \: \: triangle = \frac{1}{2} \times base \: \times height$

Therefore, the area of the triangle

$\sf = (\frac{1}{2} \times 3 \times 10 \frac{1}{2} ) {m}^{2} \\ \sf = ( \frac{1}{2} \times 3 \times \frac{21}{2} ) {m}^{2} \\ = \sf \frac{63}{4} {m}^{2} \\ = \sf 15\frac{3}{4} {m}^{2}$

Answer:

The area of the triangle is $\sf \: 15 \frac{3}{4} {m}^{2}$

Hope you could understand.

If you have any query, feel free to ask.
