Inequalities 9 – h > 2; 6, 7, 8 show work please

1 answer:

5 0

Solving the inequalities, I am guessing?

9 - h > 2
-h > -7
Divide by -1, so you flip the sign
h < 7

9 - h > 6
-h > -3
Again, divide by -1, sign flips to les than
h < 3

9 - h > 7
-h > -2
h < 2

9 - h > 8
-h > -1
h < 1

sesenic [268]

Answer:

$109.71

Step-by-step explanation:

first we find the perimeter

=2(280+200)

=2×480

=960m

now we multiply it by 4 as he wants it 4 times around

960×4

3840

now we find the fencing cost

since 35 per meter we divide it by 35

3840/35

=$<u>109.71</u>

miss Akunina [59]

Answer:

The calculation of Mrs. Hernanadez will affect by 1.375 inches lesser.

Step-by-step explanation:

Given:

Length of the Kitchen shelf = 26 3/8 inches

Width of the Kitchen Shelf = 15 1/2 inches

Incorrect measurement of the length of the kitchen shelf = 25 inches

Solution:

The Actual length of the kitchen shelf is $26\frac{3}{8}$

But she measured as 25 inches

So the error in the measurement will be

=>Correct length of the shelf - Incorrect length of the shelf

=> $26\frac{3}{8}$ - 25

Coverting the mixed fraction to fraction,

=> $\frac{211}{8}$ - 25

=> $26.375$ - 25

=>1.375

A right rectangular prism's edge lengths are 14 inches, 6 inches, and 3 1/3 inches. How many unit cubes with edge lengths of 2/5

DochEvi [55]

ANSWER

4375 unit cubes

EXPLANATION

The volume of a right rectangular prism is given by;

$V=lbh$

We substitute the given dimension to obtain,

$V=14 \times 6 \times \frac{10}{3} = 280i {n}^{3}$

The volume of the unit cube with edge lengths

$\frac{2}{5}$

$(\frac{2}{5})^{3} = \frac{8}{125} {in}^{3}$

To find the number of unit cubes that can fit inside the prism, we divide the volume of the rectangular prism by the volume of the unit cube.

$= \frac{280}{ \frac{8}{125} }$

$= 4375$
