Answer:

  4

Step-by-step explanation:

If the two numbers are 'a' and 'b', the sum of their reciprocals is ...

  \dfrac{1}{a}+\dfrac{1}{b}=\dfrac{a+b}{ab}=\dfrac{4ab}{ab}=\boxed{4}

The sum of their reciprocals is 4.

find 2 consecutive integers such that three times the square of the first is equal to seven more than five times the second
melamori03 [73]

Answer:

Step-by-step explanation:

We are looking for two numbers, N and N + 1. From the problem statement, we can setup the following equation:

3N^{2} = 5(N + 1) + 7

3N^{2} = 5N + 5 + 7

3N^{2} - 5N - 12 = 0

(3N + 4)(N - 3)

N = \frac{-4}{3}, 3

Because 3 is the only integer solution, the answer is 3 and 4.

Zach read a book for 10 minutes every weekend in the first month, 20 minutes in the second month, 40 minutes in the third month,
Lubov Fominskaja [6]
The answer is B.

This is because A is incorrect, Zach number of minutes didnt increase by an equal factor every month.

C and D are incorrect, Victoria's methods aren't exponential, but Zach's are.

So that leaves the only reasonable answer which is B.

Correct answer gets 5 stars and brainliest
Katena32 [7]

Answer:

Step-by-step explanation:

C(3 , -2)   & D (7, -8)

Distance = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

CD = \sqrt{(7-3)^{2}+(-8-(-2))^{2}}\\\\=\sqrt{(7-3)^{2}+(-8+2)^{2}}\\\\=\sqrt{(4)^{2}+(-6)^{2}}\\\\=\sqrt{16+36}\\\\=\sqrt{52}\\\\

≈ 7.2 units

Help!!! please what's is the figure​
S_A_V [24]

Hello from MrBillDoesMath!

Answer:

108 cm^2

Discussion:

The area of the logo  =

area of Trapezoid on top (I)  + area of triangle on bottom (II)

I  = (1/2) h ( b1 + b2)            h = altitude, b1, b2 = bases

  = (1/2)  6  ( 6  + 12)

  = (1/2) 6 ( 18)

  = 54

II  = (1/2) b h

   = (1/2) (12) ( 15 - 6)               => altitude of triangle = 15 - 6 NOT (1/2) 15

   =  54

I + II= 54 + 54 = 108

Thank you,

MrB
