A cube is shown below.What is the lateral surface area of the cube?

disa [49]

The lateral surface area is the surface area of the cube excluding the base and the top, which would make 4 square planes.

First we can find the area of a square plane:

4 1/2 x 4 1//2

=20 1/4 ft²

We can then multiply the area of plane by 4:

20 1/4 x 4

=81 ft²

Therefore the answer is 81 ft².

Hope it helps!

A triangle has side lengths of n, n – 3, and 2(n − 2). If the perimeter of the triangle is at least 37 units, what is the value

Vilka [71]

Answer:

n = 11

Step-by-step explanation:

The side length of a triangle are n,n-3 and 2(n-2).

The perimeter of the triangle, P = 37 units

We need to find the value of n.

Perimeter = sum of all sides

n+n-3 +2(n-2) = 37

2n-3+2n-4 = 37

4n -7 = 37

4n = 37+7

4n = 44

n = 11

So, the value of n is 11.

Dexter read 11 science fiction books and 5 history books. Lena read 9 science fiction books and 4 history books. Compare the stu

Soloha48 [4]

Answer:

1. $Dexter = 11:5$ $Lena = 9:4$

2. $Dexter = \frac{11}{5}$ $Lena = \frac{9}{4}$

3. $Dexter = \frac{44}{20}$ $Lena = \frac{45}{20}$

4. $\frac{45}{20} > \frac{44}{20}$

Step-by-step explanation:

Given

Dexter

$Science\ Fiction = 11$

$History = 5$

Lena

$Science\ Fiction = 9$

$History = 4$

Solving (1): Write as ratio

Represent Science Fiction with S and History with H

For Dexter;

$Ratio = S : H$

$Dexter = 11:5$

$Lena = 9:4$

Solving (2): Write ratio as fraction

$Fraction = \frac{S}{H}$

$Dexter = \frac{11}{5}$

$Lena = \frac{9}{4}$

Solving (3): Write as a common denominator

$Dexter = \frac{11}{5}$

Multiply by $\frac{4}{4}$

$Dexter = \frac{11}{5} * \frac{4}{4}$

$Dexter = \frac{44}{20}$

$Lena = \frac{9}{4}$

Multiply by $\frac{5}{5}$

$Lena = \frac{9}{4} * \frac{5}{5}$

$Lena = \frac{45}{20}$

Solving (4): Compare both fractions

By comparison;

$\frac{45}{20}$ is greater than $\frac{44}{20}$

So, we have:

$\frac{45}{20} > \frac{44}{20}$

What division sentence means the same asa the following subtraction sentences?

likoan [24]

The three subtraction sentences 12-4=8, 8-4=4, and 4-4=0 can be expressed as a single division sentence. The division sentence 12/4 = 3 means that, starting with the number 12, 4 can be subtracted 3 times to get zero.
Division is repeated subtraction 12 / 4 means how many 4's you can subtract from 12. 12 orange split into units of 4, then how many kids can get 4 oranges 12 - 4 = 8 1st kid 8 -4 = 4 2nd kid 4 - 4 = 0 3rd kid So 3 kid can get 4 oranges each. If we multiply 3 * 4 =12 if each 3 kids get each 4 oranges , then what was the total oranges distributed among kids Now we say that Multiplication is repeated addition. 4 * 3 = 12, 4 + 4 + 4 = 12 Further we can say that Multiplication and division is opposite of each other Like 2 * 3 = 6 6/3 = 2 6/ 2 =3 , Also division and fractions are the same, and symbols can be used interchangeably.
