finlep [7]

Speed=distance/time
suppose the distance of the first day is d, and the time is t
distance of the second day: d+0.17d=1.17d
time of the second day: t+0.2t=1.2t
speed of the second day: 1.17d/1.2t=0.975(d/t)=(1-0.025)(d/t)
so the speed of the second day is 2.5% slower than the first day.

Which fraction is equivalent to 9/13?

Doss [256]

9/13 is not a fraction that can be simplified: the two numbers don't have a divisor in common.

Let's bring all the other fractions into their simplest form too:

A.6/10=3/5
B. 2/3 This is the simplest form already
C.36/52 =18/26=9/13 ( I divided both numbers by 2 each time)

.... and we don't have to look further, we have already found the right answer: 9/13 is equivalent to 36/52.

bazaltina [42]

Answer:

Part 1) $m\angle 1=39^o$

Part 2) $m\angle 3=51^o$

Step-by-step explanation:

The picture of the question in the attached figure

Part 1) Find the measure of angle 1

we know that

The longer diagonal of a kite bisects the kite into two equal parts

That means

$m\angle 1=39^o$

In this problem the longer diagonal is the segment AC

Part 2) Find the measure of angle 3

we know that

The intersection of the diagonals of a kite form 90 degrees.

That means ----> The triangle ADO (O is the intersection point both diagonals) is a right triangle

so

$39^o+m\angle 3=90^o$ ----> by complementary angles in a right triangle

$m\angle 3=90^o-39^o=51^o$

Vertical height of the bucket is 40 cm and that of

Daniel [21]

Answer:

353cm² of metallic sheet is used to make the bucket.

The volume of water the bucket can hold is 240cm³

Step-by-step explanation:

SURFACE AREA

The area of the metallic sheet used to make the bucket is the same as the surface area.

A bucket is a cylindar. The formula for surface area is SA = 2πr² + 2πrh

2πrh is the circumference of the base multiplied by the height to find the area of the middle.

πr² is the same as the area of the base. There is only one base, so we only need πr² without the 2.

πr² = 6 because it is the base.

Solve for r by isolating.

πr² = 6cm²

r² = 6cm²÷π Divide both sides by pi

r = √(6cm² ÷ π) Square root both sides

r ≈ 1.38cm Rounded radius to two decimal places

Substitute the information into the formula for SA of bucket.

SA = πr² + 2πrh

SA = 6cm² + 2π(1.38cm)(40cm)

SA = 6cm² + 2π(55.2cm²) Multiplying units make the square of the unit

SA = 352.83...cm² Surface area of bucket, also area of metal

SA ≈ 353cm² Round to the same nujmber of decimal places in the question

Therefore 353cm² of metallic sheet is used to make the bucket.

VOLUME

The amount of water the bucket can hold is the same as the volume.

To find the volume, use the formula for volume of a cylindar V = πr²h

πr²h is the base multiplied by the height.

Since we are given the base, we do not need to find r.

Substitute the base and the height into the formula.

V = πr²h

V = (πr²)h

V = (6cm²)40cm Multiplying unit and unit squared makes the unit cubed

V = 240cm³ Volume of bucket

Therefore the volume of water the bucket can hold is 240cm³.
