Answer 1

Answer:

X= 25

Step-by-step explanation:

As AE || BC, <EAC=<ACB( alternate angles)

So, angle DCB = x

Again, <CDB+<BDA=180°

<CDB=180°-50°=130°

in ◇DBC, <x+<x+<CDB=180°

2<x=180°-130°

2<x=50°

x=25

Option D is correct. When r = 3.2 and h =3 can will need least amount of paper.

What is curved surface area ?

The lateral surface of an object is the area of all the sides of the object, excluding the area of its base and top.

Curved surface area of cylinder

The lateral surface area of a cylinder is the surface area covered by its curved surface only.

Formula for finding the curved surface area of cylinder

Total surface area of cylinder  = 2πrh

where,

r is the radius of cylinder

h is the height of the cylinder

According to the given question

we have

a soup can whose shape is of cylinder.

For finding the least amount of paper required to make label we have to calculate the curved surface

A). when, r = 2 inches and h = 6 inches

curved surface area of soup can  = 2π×2×6 = 24×3.14 =75.36 square inches

B).

when, r = 2.5 inches and h = 5 inches

curved surface area of soup can = 2×3.14×2.5×5= 78.5 square inches

C).

when r = 3 inches and h = 4 inches

curved surface area of soup can = 2×3.14×3×4= 75.36 square inches

D).

when r=3.2 inches and h = 3 inches

Curved surface area of soup can = 2×3.14×3.2×3= 60.88 square inches.

Hence, when r = 3.2 inches  and h = 3 inches can will need least amount of paper to make a new label.

Thus, option D is correct.

Clint is putting on sunscreen. He uses 2 mi to cover 50cm2 of his skin. He wants to know how many millimeters of sunscreen he needs to cover 324cm2 of his skin. How many millimeters of sunscreen will he use?

Answers

Answer:

12.96 millimeters

Step-by-step explanation:

Because he uses 2 millimeters to cover 50cm2 so we know that you would need 12 millimeters to get 300 and that 1 millimeter = 25cm2 so with some quick calculations we get 12.96.

Answers

17.5
1/2 is a fraction and as a decimal it is 0.5 so i think it is 17.5
hope i helped :)

The mixed number  [tex]17\frac{1}{2}[/tex] % is equal to 0.175.

To convert [tex]17\frac{1}{2}[/tex] % to a decimal, you divide the percentage value by 100.

First, convert the mixed number  [tex]17\frac{1}{2}[/tex] to an improper fraction.

[tex]17\frac{1}{2}[/tex] = (2×17 + 1)/2

= 35/2

Next, divide 35 by 2:

35 ÷ 2 = 17.5

Lastly, divide the result by 100:

17.5 ÷ 100 = 0.175

Therefore, [tex]17\frac{1}{2}[/tex] % as a decimal is 0.175.

Lin picked 9 and 3/4 pounds of apples, which was 3 times the weight of the apples Andre picked. How many pounds of apples did Andre pick

Answers

Answer:3 1/4

Step-by-step explanation:

L=9 3/4

L= 39/4 (multiply 9x4 and add 3)/4

3(A)=39/4 (Note: A= Andre)

(1/3)(3/1)a= 39/4 * 1/3

When you cross the 3 in the denominator and divide 3 into 39 it changes that into 13.

13*1=13 numerator and 4*1=4 denominator so it will be 13/4

When you divide 13/4 it becomes 3 1/4

So 3 1/4 lbs of Apples is the correct answer.

Andre picked 13/4 pounds of apples, which is equivalent to 3 and 1/4 pounds of apples.

What is Fraction?

A fraction represents a part of a whole.

Let us consider x to represent the weight of apples that Andre picked.

We know that Lin picked 9 and 3/4 pounds of apples, which was 3 times the weight of the apples Andre picked

9 and 3/4 = 3x

We have to solve for x, divide both sides of the equation by 3:

9 and 3/4 ÷ 3 = x

We can convert the mixed number to an improper fraction first:

(9 × 4 + 3) ÷ 4 = 39/4

Now we can divide:

39/4 ÷ 3

= 13/4

=[tex]3\frac{1}{4}[/tex]

Hence, Andre picked 13/4 pounds of apples, which is equivalent to 3 and 1/4 pounds of apples.
