Answer:

<em>He will bake 300 loaves of bread.</em>

Step-by-step explanation:

Paul bakes loaves of bread and bread rolls in the ratio of 2 : 5

Suppose, the number of loaves of bread he will bake =x

Given that, he bakes 750 bread rolls.

So, according to the given ratio, we will get......

\frac{loaves\ of\ bread}{bread\ rolls}=\frac{2}{5}\\ \\ \frac{x}{750}=\frac{2}{5}\\ \\ 5x=1500\ [by\ cross\ multiplication]\\ \\ x=\frac{1500}{5}\\ \\ x=300

So, he will bake 300 loaves of bread.

iragen [17]

Answer:

3964 in³

Step-by-step explanation:

volume of sphere:  V = 4/3 πr³

v₁ = 4/3 x 3.14 x 7³ = 1436

volume of prism: v = Bh     B = 15 x 18 = 270    h = 20

v₂ = 270 x 20 = 5400

v₂ - v₁ = 5400 - 1436 = 3964 in³

The probability would be 0.000017.

70% of the 20 questions is 14 questions correct.  Using a binomial distribution for this, we have:

Marta_Voda [28]

Answer:

z_1\times z_2=-14+27i

Step-by-step explanation:

We are given that two complex numbers

z_1=3-4i

z_2=-6+i

We have to find the product of two complex numbers

z_1\times z_2=(3-4i)(-6+i)

z_1\times z_2=3(-6+i)-4i(-6+i)

z_1\times z_2=-18+3i+24i-4i^2

z_1\times z_2=-18+27i+4 (i^2=-1)

z_1\times z_2=-14+27i

JulsSmile [24]

Answer:

f(x) = 26000000(.85)^x + 2,000,000

f(1) = 26,000,000

f(2) = 24100000

f(3) = 22485000

f(4) = 21112250

Geometric, it is going down by a %, not a fixed number

Year 5, less pollution

f(8) = 9,084,753.65

Step-by-step explanation:

f(2) = 26,000,000 (.85)^2 + 2,000,000

f(2) = 24100000

f(3) = 26,000,000 (.85)^3 + 2,000,000

f(3) = 22485000

f(4) = 26,000,000(.85)^4 + 2,000,000

f(4) = 21,112,250

f(8) = 26,000,000(.85)^8 + 2,000,000

f(8) = 9,084,753.65
