Estimate the total weight of two million pounds worth of two pence coins in kilograms. A two pence coin weighs 7.1g.

Answers

Answer 1

Answer: 710,000 kg

Step-by-step explanation:

There are 100 pence in one pound.

The number of two pence coins in 1 pound is therefore:

= 100 / 2

= 50 coins

In 2 million pounds therefore, there will be:

= 50 * 2,000,000

= 100,000,000 two pence coins

If one coin weighs 7.1g, weight is:

= 100,000,000 * 7.1

= 710,000,000 g

A kg is 1,000 grams so the weight in kg is:

= 710,000,000/1,000

= 710,000 kg

density of the cube is 9.86 g/cm³ and the volume is 150cm³ work out the mass in kg

Answers

Mass= Density *Volume

9.86 g/cm3 *150 cm3 =1479g

1479 g to kilograms

1479g= x

1000g = 1 kg

x = 1479 g / 1000 x = 1.479 kg.

A lot runs between two parallel streets. The length of the lot on one of the streets is 160-ft. The length of the lot on the other street is 100-ft. The area of the lot is 14,170 square feet. How far apart are the two streets?

Answers

Answer:

Step-by-step explanation:Area = 1/2(b1 + b2)x h

Area = 18,000 ft^2

b1 = 80 ft

b2 = 100 ft

18,000 = 1/2(80 + 100) x h

36,000 = (180)h

h = 36,000/180

h = 200ft.

This is the distance between streets.

Hope this helps :-)Area = 1/2(b1 + b2)x h

Area = 18,000 ft^2

b1 = 80 ft

b2 = 100 ft

18,000 = 1/2(80 + 100) x h

36,000 = (180)h

h = 36,000/180

h = 200ft.

This is the distance between streets.

Hope this helps :-)

A regular pentagon and an equilateral triangle have the same perimeter. The perimeter of the pentagon is 5(x-2) inches. The perimeter of the triangle is 4(1/2x+2) inches. What is the perimeter of each figure?

Answers

Answer:

20 inches.

Step-by-step explanation:

We equate the perimeters:

5(x - 2) = 4(1/2x + 2)

5x - 10 = 2x + 8

5x - 2x = 8 + 10

3x = 18

x = 6

The perimeters = 5(6-2)

= 20 inches.

Name the slope and y-intercept of the graph of 3x - 2y = 18 A. B. 2 3 -6 6 C. -3.-9 D. 2 -9​

Answers

Answer:

D. 3/2, -9

Step-by-step explanation:

First, rearrange the equation 3x - 2y = 18 into the slope-intercept form of y = mx + b:

3x - 2y = 18

2y = 3x - 18

y = 3x/2 - 9

from this, u can tell that the slope is 3/2 and the y-intercept is -9 (option D)

Simplify 5a – (2a + 6)

Answers

Answer:

Step-by-step explanation:

Add '-2a' to each side of the equation.

5a + -2a = -6 + 2a + -2a

Combine like terms: 5a + -2a = 3a

3a = -6 + 2a + -2a

Combine like terms: 2a + -2a = 0

3a = -6 + 0

3a = -6

Divide each side by '3'.

a = -2

Simplifying

a = -2

5a -2a -6

3a -6

A cinema has 300 seats. 60% are filled. How many are empty? i will give brainliest

Answers

180 are empty
............

Answer:

120 seats

Step-by-step explanation:

Total seats in the hall = 300

Percentage of filled seats = 60 %

Number of seats filled = (60 / 100) 300

                                     = 60 * 3

                                     = 180

Therefore, number of empty seats = 300 - 180

                                                          = 120

A ball is projected upward from ground level. After t seconds, it’s height in feet is a function defined by f (t) = -16t^2 + 96t. In how many seconds will the rocket be at a height of 128 ft above the ground?

Answers

Answer:

t = 2 s and t = 4 s

Step-by-step explanation:

A ball is projected upward from ground level. After t seconds, it’s height in feet is a function defined by,

[tex]f (t) = -16t^2 + 96t[/tex]

We need to find in how many seconds will the rocket be at a height of 128 ft above the ground.

It means,

[tex]128= -16t^2 + 96t\\\\-16t^2+96t-128=0\\\\16(-t^2+6t-8)=0\\\\(-t^2+6t-8)=0\\\\-t^2+4t+2t-8=0\\\\t(-t+4)-2(-t+4)=0\\\\(t-2)=0\ and\ (-t+4)=0\\\\t=2\ and\ t=4[/tex]

So, it will be at a height of 128 feet at 2 second and 4 second.

Y=4-2x 3y-2x=4 solve using substitution

Answers

Answer:

x=1 y=2

Step-by-step explanation:

y=4-2x             3y=4+2x

3*(4-2x)=4+2x

12-6x=4+2x

12-4=2x+6x

8x=8

x=1

y=4-2*1

y=2

First turn the equation y=4-2x into a y=Mx+b formula. It would be y=-2x+4. Then plug it in into the y on the second equation. I’d be 3(-2x+4)-2x=4. Then solve. The answer is x=1. Hope it helped. :)

Paul invests £150 in a bank account paying 2% interest per annum for 10 years. Work out how much money he has in the account at the end of the 10 years

Answers

Answer: £180

Step-by-step explanation:

The interest gotten for the 10 years will be calculated as:

= Principal × Rate × Time

= 150 × 2% × 10

= 150 × 0.02 × 10

= 30

The amount he has in the bank account at the end of the 10 year will be:

= Principal + Interest

= £150 + £30

= £180
