Answers

Answer:

JK = 3[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos60° = [tex]\frac{1}{2}[/tex] , then

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{JK}{JL}[/tex] = [tex]\frac{JK}{6\sqrt{3} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2JK = 6[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

JK = 3[tex]\sqrt{3}[/tex]

Beth normally cycles a total distance of 56 miles per week.
She increases her distance by 15% each week for the next three weeks.
How many miles will she cycle in the third week?
(3 marks)
miles

Answers

Answer:

She will cycle 85.169 miles in the third week.

(round if needed)

Step-by-step explanation:

56÷100=0.56 (this is 1%)

0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)

repeat for the other 3 weeks

64.4÷100=0.644

0.644 x 15 + 64.4 = 74.06

74.06÷100=0.7406

0.7406 x 15 + 74.06 = 85.169

Beth will cycle a distance of 85.169 miles in the third week.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If john obtained a score of 57% on his exam, that corresponds to 57 out of 100.

Beth rides her cycle 56 kilometers each week on average.

For the next three weeks, she will increase her distance by 15% each week.

As per the given condition, the required solution would be as

⇒ 56 / 100 = 0.56

⇒ 0.56 × 15 + 56 = 64.4

If we obtain 15%, add 56 (the initial amount) because there is a 15% increase.

Repeat for the remaining three weeks.

⇒ 64.4 / 100 = 0.644

⇒ 0.644 × 15 + 64.4 = 74.06

⇒ 74.06 / 100 = 0.7406

⇒ 0.7406 × 15 + 74.06 = 85.169

Therefore, she will cycle a distance of 85.169 miles in the third week.

Answer: y=12 x =9

Step-by-step explanation:

In a parallelogram the diagonals bisect each other making them equal.

this means 2y + 6 = 30

we can rearrange this as 30 - 6 = 2y

24 = 2y  therefore y = 12

3x - 3 = 24

We can rearrange this as 24 + 3 = 3x

3x = 27

27 / 3 = 9

x = 9

In 5 1/2 hours of driving, Samuel traveled 264 miles. At that rate, how long would it take him to travel 348 miles?

Answers

Answer: It will take Samuel 7 1/4hours to travel 348miles

Step-by-step explanation:

Step 1

Time spent in Driving  = 5 1/2 hrs

Distance he drove  = 264 miles

There the speed he drove at = Distance / Time

Speed = Distance / =Tme

= 264/ 5 1/2= 264/ 11/2= 264 x 2/ 11=528/11= 48 miles per hour

Step 2

At The same rate of 48miles per hour, it will take him to travel 348 miles

Therefore the time taken = Distance / speed

Time = 348 miles/48 miles per hour

Time=7.25 = 7 1/4 Hours

Find the total surface area of this cylinder.
Give your answer to 1 decimal place.
7 cm
15 cm

Answers

Answer:

For the first figure :

Cylinder :

Radius =7cm

height = 15cm

Total Surface Area:

2 \times \pi \times r(h + r)2×π×r(h+r)

= 2×22/7×7 (15+7)

= 22×44

= 968 cm sq.or 9.68m sq.

For the second figure :

Diameter = 24cm (radius= 24/2= 12cm)

•Height = 18 cm

Total Surface area:

2 \times \pi \times r(h + r)2×π×r(h+r)

= 2×22/7×12 (18+12)

= 2×22/7×12 (30)

= 2×22×12×5

= 2640 cm. sq or 26.4 m.sq

The total surface area of this cylinder is 967.1cm²

Surface area of a cylinder.

The formula for calculating the total surface area of a cylinder is expressed as:

TSA = 2πr(r+h)

Given the following

radius r = 7cm

Height h =15cm

Substitute

TSA = 2π(7)(7+15)

TSA = 14π(22)

TSA=967.1 cm²

The total surface area of this cylinder is 967.1cm²

Jonathan is making his favorite pasta dish. He serves his mom 1/12 of the pot of pasta and his brother 1/6 of the pot. How much of the pot is left over? PLS HELP I HATE MATH

Answers

Answer:

3/4 of the pot left.

Step-by-step explanation:

If the mom eats a 1/12 of the pot and then the brother also eats a 1/6 of the pot, then it is 9/12 left of pasta still. The reason for that is since 1/6 is equivalent to 2/12 so 1/12 plus 2/12 is 3/12, and if u subtract 3/12 from 12/12 it will give you 9/12 which can be simplified to 3/4 left of the pot.

Answer:

3/4 of the pot is left over

Answer:

The value of ∠BDC is equal to 68°.

Step-by-step explanation:

It is given that,

∠BDA is a straight angle.

ATQ,

∠BDC+∠ADC=180 (Linear pair)

-7x+12+(-8x)+48 = 180

-7x+12-8x+48 = 180

-15x+ 60 = 180

-15x = 180-60

-15x = 120

x = -8

So,

∠BDC = -7x+12

= -7(-8) + 12

= 56+12

= 68°

So, the value of ∠BDC is equal to 68°.
