Mathematics
1 answer:
MakcuM [25]3 years ago
3 0

Answer:

The expression that belongs in the box is 8 x 4

Option C is correct answer.

Step-by-step explanation:

We need to find Which expression belongs in the box?

(3 \times 8)  \times 4= 3 \times (------)

The property applied here is associative property of multiplication.

Associative property of multiplication states that:

(a \times b)\times c = a \times (b \times c)

So, if we apply the property to our question we have:

a = 3

b = 8

c = 4

So, the expression will become: (3 \times 8)  \times 4= 3 \times (8 \times 4)

So, the expression that belongs in the box is 8 x 4

Option C is correct answer.

This year the fifth grade collected 216 fewer plastic containers than the fourth grade.How many plastic containers did the fifth
kap26 [50]

Let number of plastic containers collected by fourth grade= x

Then number of plastic containers collected by fifth grade students=x-216

OR

If number of plastic container collected by fifth grade is y

then number of plastic container collected by fourth grade=y+216

So, we can write it as follows

⇒ number of plastic containers collected by fourth grade= number of plastic containers collected by fifth grade +216

Find the surface area of the square pyramid below if the length of the sides of the base are 10 cm, and the slant height is 15 c
Damm [24]

The surface area of the square pyramid if the length of the sides of the base are 10 cm, and the slant height is 15 cm is 416.2 cm²

<h3>Surface area</h3>

Surface area of the square pyramid

= a² + 2a√a²/4 + h²

where,

  • a = sides of base = 10 cm
  • h = slant height = 15 cm

Surface area of the square pyramid

= a² + 2a√a²/4 + h²

= 10² + 2(10)√10²/4 + 15²

= 100 + 20√100/4 + 225

= 100 + 20√25 + 225

= 100 + 20√250

= 100 + 20(15.81)

= 100 + 316.2

= 416.2 cm²

Need help with this question <br><br> 2 + (4h- 1) = 13h<br><br> Need All Steps Plz
vredina [299]

Answer and Step-by-step explanation:

For this equation, we are solving for h.

We are given the equation:

2 + 4h - 1 = 13h

<u>First, we need to </u><u><em>Simplify</em></u><u> the equation.</u>

2 - 1 + 4h = 13h

1 + 4h = 13h

<u>Now, we need to </u><u><em>Subtract</em></u><u> 4h from both sides of the equation.</u>

1 + 4h - 4h = 13h - 4h

1 = 9h

<u>Finally, we </u><em><u>Divide</u></em><u> both sides by 9 to get h.</u>

\frac{1}{9}  = h

<u>h is equal to </u>\frac{1}{9}<u>.</u>

To check your answer, we plug \frac{1}{9} back into the given equation.

2 + 4(\frac{1}{9} ) - 1 = 13(\frac{1}{9} )\\\\\\\\2 + \frac{4}{9} -1 = \frac{13}{9} \\\\\\1 = \frac{9}{9} \\\\1 = 1

<u>I hope this helps!</u>
