A. top left

here an explanation, say you have two really big pizzas that are both the same exact size, now say you cut 20 pieces out of the first on and 22 out of the second. since theres more slices on the second one the pieces will be slimmer. now if you remove 17 from both, the first pizza with 20 slices will have more left over because since 20 is less than 22 the slices from the first pizza are wider making for more pizza per slice.

$ac = 56$

Step-by-step explanation:

$6x + 3 = 7x - 1$

5 (x minus 6) = 2 (x + 3)?

deff fn [24]

Answer:

12

Step-by-step explanation:

5(x-6)=2(x+3)

multiply

5*x and 5*6. 2*x and 2*3

5x-30=2x+6

minus 5x and 2x

3x-30=6

add 30 to 6

3x=36

divide both sides by 3 and the 3x cancels so 36÷3

x=12

How do you solve this?? Please help!

Aleks04 [339]

f = (f1 f2) / (f1 + f2)

f(f1 + f2) = f1 f2

f f 1 + f f 2 = f1 f 2

f1 f2 - f f2 = f f1

f2 (f1 - f) = f f1

f2 = (f f1) / (f1 - f) <==== solution

It should be ten times greater since,

The temperature at any random location in a kiln used in the manufacture of bricks is normally distributed with a mean of 1000 a

NeX [460]

Answer:

b. 2.28%.

Step-by-step explanation:

Mean temperatue (μ) = 1000°F

Standard Deviation (σ) = 50 °F

For any temperature value, X, the z-score is given by:

$z=\frac{X-\mu}{\sigma}$

For X= 900°F

$z=\frac{900-1000}{50}\\z=-2.0$

A z-score of -2.0 corresponds to the 2.28-th percentile of a normal distribution. Therefore, the probability that X<900 is:

$P(X$
