8 1/4 pounds of flour are used to make 4 1/8 papier-mâché pasta recipe how much flour is used in one recipe

Answers

2 pounds of flour are required to make 1 recipe, as of the given condition.

Given that
8 1/4 pounds of flour are used to make 4 1/8 paper-mâché pasta recipe how much flour is used in one recipe is to be determined.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

Flour = 8 1/4
Flour = 8.25 pounds
The proportion of the recipe made corresponding to 8.25 pounds of flour = 4.125
Now,
For 1 recipe = 8.25 / 4.125 = 2 pounds of flour are needed.

Thus, 2 pounds of flour are required to make 1 recipe, as of the given condition.

What value of d makes the equation true? d – 34.8 = 5.3

Answers

$d -34.8 =5.3\nd - 34.8 + 34.8 = 5.3 + 34.8 \n d = 5.3 + 34.8\n\n\boxed {d=40.1}$

To calculate the volume of a cylinder, we have equation like this: V = πd 2 4 h = πr 2h d is the diameter, r is the radius and h is its height. We can measure the diameter (r = d 2 ) and height directly. To calculate the confidence interval of the volume, we should use the propagation of errors. We use the micrometer screw to measure the diameter. The minimum interval on the screw is 0.01mm. What is the confidence interval for δd and δr?

Answers

Answer:

$\delta d =$ +/- 0.01 mm

$\delta r =$ +/- 0.02 mm

Step-by-step explanation:

$\delta d$ . The error of a quantity directly measured is the uncertainty of the tool used for measuring. So error for diameter is 0.01 mm.

$\delta r$ . The error of a quantity obtained multiplying/dividing a measure by a constant is calculated multiplying/dividing the measure uncertainity by the same constant. Radius is calculated as r=2*d, so we calculate $\delta r$ multiplying the diameter uncertainty by 2 ( $\delta r = 2*0.01=0.02$ ).
