Answer:

17.5% of 360 = 63

Step-by-step explanation:

We are given a process of finding 17.5% of 120. Following the same process we have to determine the 17.5% of 360.

17.5% can be break down as 10% + 5% + 2.5%

Thus,

STEP 1 : Find 10% of 360 , we get,

$\frac{10}{100} \times 360=36$

STEP 2 : find 5% of 360, we get,

$\frac{5}{100} \times 360=18$

STEP 3: find 2.5% of 360 , we get,

$\frac{2.5}{100} \times 360=9$

STEP 4: 17.5% of 360 = 10% of 360 + 5% of 360 + 2.5% of 360

⇒ 17.5% of 360 = 36 + 18 + 9

⇒ 17.5% of 360 = 63

Rectangle JKLM:J(-3, 8), K(-3,-1), L(4, -1),

Maslowich

Answer:

The perimeter of the Rectangle JKLM is 32 unit.

Step-by-step explanation:

Consider the provided coordinates.

Rectangle JKLM: J(-3, 8), K(-3,-1), L(4, -1), M(4,8)

First plot the points as shown in figure:

The required figure is shown below:

Now find the distance between JK by using the distance formula.

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$d=\sqrt{\left(-3-\left(-3\right)\right)^2+\left(-1-8\right)^2}=9$

Therefore, the length of JK is 9 unit.

Now find the length of the side JM

$d=\sqrt{\left(4-\left(-3\right)\right)^2+\left(8-8\right)^2}=7$

Therefore, the length of JM is 7 unit.

The perimeter of rectangle is: $P=2(l+b)$

Therefore,

$P=2(7+9)$

$P=2(16)$

$P=32$

Hence, the perimeter of the Rectangle JKLM is 32 unit.

Plz help ASAP! I will mark brainliest if correct

MaRussiya [10]

A = L^2
A = L^2 = 2^2 + 4^2 (Pythagorean’s theorem)
A = L^2 = 20
Therefore the area of the square is 20 units square.

Between 3 P.M and 3:30 P.M., the minute hand of a clock moves 180 degrees. How many degrees does the hour hand move during that

AURORKA [14]

Answer:

Between 3 P.M. and 3:30 P.M the hour hand moves 15°.

Step-by-step explanation:

The rotation of the minute hand of a clock between 3 P.M. and 3:30 P.M. is from the the 12 hour mark to the 6 hour mark which is half of one complete cycle

One complete cycle of clock rotation = 360° = 12 hours

Therefore, the hour hand rotates 360/12 = 30° for each hour

Given that the time between 3 P.M. and 3:30 P.M. is 30 minutes = 1/2 an hour

The rotation of the hour hand between 3 P.M. and 3:30 P.M = Half the rotation for 1 hour

∴ The rotation of the hour hand between 3 P.M. and 3:30 P.M = 30°/2 = 15°

Between 3 P.M. and 3:30 P.M the hour hand moves 15°.

Someone can help me in this question!

Nitella [24]

Answer:

ACB=61°, BAC=58°, AEF=65°

Step-by-step explanation:

C = 122°, 180-122=58° ACB= 122°÷2=61°

61°+61°+A=180, hence 58°

65 because of opposite angles, they are equal
