Answer:

**Answer:**

2.57 - 1.75 = 0.82

**Step-by-step explanation:**

Let us assume that we need to find the value of 2.57 - 1.75 i.e. we need to subtract 1.75 from 2.57. It can be done as follows :

The first number is 2.57 and other no is 1.75.

In 2.57, 2 is in ones place, 5 is in tenths place and 7 is in hundredths place.

In 1.75, 1 is in ones place, 7 is in tenths place and 5 is in hundredths place.

Subraction :

2.57

- 1.75

= 0.82

**Hence, the value of 2.57 - 1.75 is 0.82**

(b) the surface area of the cube maximum possible error relative error percentage error cm Need Help? ReadTalk to Tuter

**Answer with Step-by-step explanation:**

We are given that

Side of cube, x=30 cm

Error in measurement of edge, cm

(a)

Volume of cube,

Using differential

Substitute the values

**Hence, the maximum possible error in computing the volume of the cube**

**=**

Volume of cube,

Relative error=

**Relative error=0.05**

**Percentage error=%**

**Hence, relative error in computing the volume of the cube=0.05 and **

**percentage error in computing the volume of the cube=5%**

(b)

Surface area of cube,

**The maximum possible error in computing the volume of the cube=**

Relative error=

**Relative error in computing the volume of the cube=0.033**

**The percentage error in computing the volume of the cube=%**

**Answer:**

8

**Step-by-step explanation:**

(8*4)3=96

3*4=12

12*8=96

**Answer:**

**Step-by-step explanation:**

So we have:

First, add 8 to both sides. The right will cancel:

Now, notice that A is multiplied to B. So, the isolate A, divide both sides by B. The right will cancel:

And we're done!

**Answer:**

7.56 quarts of antifreeze in the resulting mixture, and 37.8% of the resulting mixture is antifreeze.

**Step-by-step explanation:**

8 * .45= 3.6 quarts antifreeze

12 * .33= 3.96 quarts antifreeze

3.6 + 3.96=** 7.56 quarts of antifreeze in the resulting mixture **

7.56 quarts/ 20 quarts (12 + 8) * 100= **37.8%**

In the combined solution, there are 7.56 quarts of anti-freeze, which equals 37.8% of the total solution.

To solve this problem, we first need to calculate how many quarts of anti-freeze are in each solution, then add them together.

First, we have 8 quarts of a solution that is 45% anti-freeze. To find how many quarts of the solution is anti-freeze, we multiply the total amount by the **percentage:** 8 quarts * 0.45 = 3.6 quarts anti-freeze.

Next, we have 12 quarts of a solution that is 33% anti-freeze. Doing the same calculation as before, 12 quarts * 0.33 = 3.96 quarts anti-freeze.

Now, to find the **total quarts** of anti-freeze in the combined solution, we simply add the two amounts together: 3.6 quarts + 3.96 quarts = 7.56 quarts.

The total amount of solution is 8 quarts (from the first solution) + 12 quarts (from the second) = 20 quarts.

To find the percent of anti-freeze in the final solution, we divide the total amount of anti-freeze by the total amount of solution: (7.56 quarts / 20 quarts) * 100 = *37.8%*. Therefore, the resulting mixture is 37.8% anti-freeze.

The requried **volume **of the **pyramid **is 64.9 cubic meters.

Volume is defined as the mass of the object per unit density while for geometry it is calculated as **profile****area **multiplied by the length at which that profile is **extruded**.

The first step is to find the area of the square base. Since the perimeter of the base is 15.4, each side of the square has a length of:

15.4 / 4 = 3.85

Therefore, the **area **of the **base **is:

A = (3.85)² = 14.8225 square meters

The volume of a pyramid is given by the formula:

V = (1/3) * A * h

where A is the area of the base and h is the height of the pyramid. Substituting the values given in the problem, we get:

V = (1/3) * 14.8225 * 13.1

V = 64.91925 cubic meters

Rounding to the nearest tenth of a cubic meter, we get:

V ≈ 64.9 cubic meters

Therefore, the **volume **of the **pyramid **is approximately 64.9 cubic meters.

Answer: 69.3

Explanation: So if the height is 13.1, that means that the length is 2.3. And to find volume, you do length times width times height. So the width would be 2.3 because it is a even square if that makes since. Now 2.3 times 2.3 is 5.29. Now we multiply 5.29 by 13.1. The answer is 69.299. Now we round this to the nearest tenth, so the answer would be 69.3.
