Can someone help me with this pls?

Pavlova-9 [17]

Answer:

1176 $cm^{3}$

Step-by-step explanation:

First, calculate the volume as if it was a full rectangle.

Volume formula:

length x width x height

16 x 6 x 21 = 2016 $cm^{3}$ (this is the volume if this was a full rectangle)

Now to calculate the size of the missing part we do the same thing

10 x 6 x 14 = 840 $cm^{3}$

To work out the volume of this shape, we need to subtract the volume of the missing part from the volume of the rectangle

2016 - 840 = 1176 $cm^{3}$

I hope this helped :-)

A cake recipe calls for 1.5 cups of milk and 3 cups of flour. Seth made a mistake and used 5 cups of flour. How many cups of mil

Alex Ar [27]

Answer:

Step-by-step explanation:

Step one:

we are told that the ratio of milk to flour is 1.5cups to 3 cups

in other words, to prepare cake we need 1.5 cup of milk and 3 cups of flour

if we use 5 cups of flour we can balance up using the relation below

1.5cups of milk require 3 cups of flour

x cups of milk require 5 cups of flour

cross multiply we have

x=1.5*5/3

x=7.5/3

x=2.5cup of milk

The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.05 inches and a standard dev

Viefleur [7K]

Answer:

6.68% or 0.0668

Step-by-step explanation:

Mean sheet length (μ) = 30.05 inches

Standard deviation (σ) = 0.2 inches

In a normal distribution, for any length X, the z-score is determined by the following expression:

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

For X = 29.75, the z-score is:

$z=\frac{29.75-30.05}{0.2}\\z=-1.5$

A z-score of -1.5 corresponds to the 6.68th percentile of a normal distribution.

Therefore, the probability that a sheet selected at random will be less than 29.75 inches long is 6.68%.
