Answer:

The correct option is 1.

Step-by-step explanation:

The given expression is

3.5\times 2+9(7.1+0.5)+4

To solve these type of expressions we have a rule that is known as BODMAS.

BODMAS = brackets of division, multiplication, addition, subtraction.

It defined the order of calculations. It means first we have solve the brackets, then division, then multiplication, after that addition and last subtraction.

So according to BODMAS, Claudio should simplify the bracket first.

The bracket of given expression is (7.1+0.5).

The simplification of given expression is shown below.

3.5\times 2+9(7.6)+4               (Brakets)

7+68.4+4                                  (Multiplication)

79.4                                          (Addition)

Therefore he will solve (7.1+0.5) first. So, option 1 is correct.

In isosceles triangle WXY, XY is 13 inches in length and WY is 10 inches. What is the length of XZ? answer asap please
Anna11 [10]
<h3>Answer:  12 inches</h3>

=============================================================

Explanation:

Notice the double tickmarks on segments WZ and ZY. This tells us the two segments are the same length. Let's say they are m units long, where m is a placeholder for a positive number.

That would mean m+m = 2m represents the length of segment WY, but that's equal to 10 as the diagram shows. We have 2m = 10 lead to m = 5 after dividing both sides by 2.

We've shown that WZ and ZY are 5 units long each. In short, we just cut that length of 10 in half.

-----------------------------------

Let's focus on triangle XYZ. This is a right triangle with legs XZ = unknown and ZY = 5. The hypotenuse is XY = 13.

We'll use the pythagorean theorem to find XZ

a^2 + b^2 = c^2

(XZ)^2 + (ZY)^2 = (XY)^2

(XZ)^2 + (5)^2 = (13)^2

(XZ)^2 + 25 = 169

(XZ)^2 = 169-25

(XZ)^2 = 144

XZ = sqrt(144)

XZ = 12

Segment XZ is 12 inches long.

A shelf is built on a wall, as shown below. What is the value of x?<br> (2x+1) + (3x-1)
Hoochie [10]

Answer:

x = 18

Step-by-step explanation:

We need to find the value of x.

We know that the sum of angles of a triangle is equal to 180°. So, using this property,

2x+1+3x-1+90 = 180

2x+3x = 180-90

5x = 90

x = 18

So, the value of x is equal to 18.

2. If the data in the table were displayed in a circle graph, which percent would NOT appear in the graph? Round to the nearest
german
Adding the numbers gives us a total of 65

Jan = 20/65 = 30.7% = 31%
Feb = 25/65 = 38.4% = 38%
Mar = 1/65 = 1.5% = 2%
Apr = 3/65 = 4.6% = 5%
May = 16/65 = 24.6% = 25%

I believe ur answer is 30%
