Answer:

15/16 cm

Step-by-step explanation:

The drill must go 3/8 of the way from one side of the sheet to the other.  The depth that this drill must reach is found by multiplying 2.5 cm by 3/8:

25       3       5         3

----- * ----- = ------ * ------ = 15/16 cm

10       8        2        8

Explain why the exponents cannot be added in the product 12 to the power of three times 11 to the power of 3
egoroff_w [7]
Normally, we could add exponents.
however, that only is possible when the bases are the same
recall what exponents mean

12³=12*12*12


so we cannot add exponents for 12³*11³ because that means 12*12*12*11*11*11
it would not equal 12⁶ or 11⁶



or you  could refer to the rule
(x^a)(x^b)=x^{a+b}
notice when x=x then we can add the bases


fun fact below
we can reverse a previous exponential rule like this
since (ab)^c=(a^c)(b^c) then (a^c)(b^c)=(ab)^c
therefor
12^3*11^3=(12*11)^3



we can't add the exponents because the bases are not the same

Combine like terms and solve x<br><br><br> 12x + 3 - 4x - 6 = 5<br><br> 5x - 4 + 7 + 6x - 4x = 24
Lisa [10]

Answer:

12x + 3 - 4x - 6 = 5

x=1

5x - 4 + 7 + 6x - 4x = 24

x=3

Which reason justifies the following statement?
amid [387]

Answer:

(A) Complements of the same  angle are congruent.

Step-by-step explanation:

Since, ∠CEF is complementary to ∠DCF, therefore

∠CEF+∠DCF=90°                                 (1)

Also, ∠CEG=∠CEF+∠FEG

⇒90°=∠CEF+∠FEG                              (2)

Therefore, from(1) and (2), we get

∠CEF+∠DCF=90°    

∠CEF+∠FEG=90°

Subtracting both the equations, we get

  ∠DCF-∠FEG=0

∠DCF=∠FEG.

Hence, ∠DCF≅∠FEG by the rule: Complements of the same  angle are congruent.
