4(y+8)=100 help me pls due today

Answers

Answer:

y=17

Step-by-step explanation:4(y+8)=100

We move all terms to the left:

4(y+8)-(100)=0

We multiply parentheses

4y+32-100=0

We add all the numbers together, and all the variables

4y-68=0

We move all terms containing y to the left, all other terms to the right

4y=68

y=68/4

y=17

   

Answer:

[tex]4(y + 8) = 100 \\ 4y + 32 = 100 \\ 4y = 100 - 32 \\ 4y = 68 \\ y = \frac{68}{4} \\ \boxed{y = 17}[/tex]

y=17 is the right answer.

A circle has an area of 314.1592. What is the diameter? (round to the nearest whole number)

Answers

Answer:

20

Step-by-step explanation:

The area of a circle is equal to pi*radius^2

We can then write this as

314.1592=π*r^2

We then divide pi to get

100=r^2

take the square root and you find that the radius equals around 10

The diameter is always equal to the radius times two which means that the diameter is 20

A cable 33m long runs from the top of a utility pole to a point on the ground 22m from the base of the pole. How tall is the utility pole

Answers

Answer:  24.6 m

Step-by-step explanation:

The shape described is that of a right-angled triangle.

This means that the height of the pole can be calculated using the Pythagorean rule.

c² = a² + b²

c = hypothenuse which is the length of the cable to the ground = 33m

a = base = distance from base of pole to cable point on ground = 22m

b = height of pole

33² = 22² + b²

1,089 = 484 + b²

b² = 1,089 - 484

b² = 605

b = √605

b = 24.6 m

A rectangle has a length of 5r - 6 and a width of 2r + 3. Find the area.

Step-by-step explanation:

The area of a rectangle is its length multiplied by its width, so in this case:

We can solve this using the distributive property to expand the right side, and then combine like terms to simplify:

Step-by-step explanation:

The ratio of money in Terry's bank account to Faye's bank account was 3:5.
Terry then put £220 in his account and Faye withdrew £300 from her account.
They now had the same amount in their accounts.
How much did Terry initially have?

Answers

Answer:

Terry had £780 initially and Faye had £1300

Step-by-step explanation:

System of Equations

We'll call the following variables:

x = Terry's balance in his bank account

y = Faye's balance in her bank account

The initial relation between them is:

[tex]\frac{x}{y}=\frac{3}{5}[/tex]

Cross-multiplying:

5x = 3y        [1]

If Terry put £220 in his account he had x+220 and if Faye withdrew £300 from her account, she had y-300. Both quantities are equal, thus

x + 220 = y - 300

Subtracting 220:

x = y - 520         [2]

Substituting in [1]

5(y - 520) = 3y

Multiplying:

5y - 2600 = 3y

Adding 2600 and subtracting 3y:

2y = 2600

Dividing by 2:

y = 1300

From [2]:

x = 1300 - 520

x = 780

Terry had £780 initially and Faye had £1300

3 consecutive integers is 234. What is the equation to solve this equations and what are the 3 integers?

Answers

Answer:

1. The equation to solve this equations is:

= 3x = 231

2. The three integers are 77, 78 and 79.

Step-by-step explanation:

The sum of 3 consecutive integers = 234

let x = first integer

let x+1 = second integer

let x+2 = third integer

Therefore,

= x + x + 1 + x + 2 = 234

simplified to:

= 3x = 231

b) Adding three consecutive numbers adds the smaller number to itself three times, and then adding 1 for the second number, and two for the third number. So, the sum of the three consecutive numbers is divisible by 3.  Therefore, to get the second (or middle) number, divide the total by 3, and then subtract 1 and add 2 to get the first and the third numbers, respectively.

CD is a median of triangle ABC and M is the
centroid. If CM = x +5 and CD = 5x + 1,
what is the value of x ?

Answers

Answer: a) [tex]\dfrac{13}{7}[/tex]

Step-by-step explanation:

Median: Line segment from one vertex of a  triangle to the midpoint of the opposite side. i.e. it bisects the opposite side.

Centriod: Point of intersection of a triangle of its medians

.Also, it is [tex]\dfrac23[/tex] of the distance from vertex to the midpoint of opposite side.

Given:  CD is a median in triangle ABC and M is centriod.

[tex]\Rightarrow CM=\dfrac23 CD[/tex]

Since CM = x +5 and CD = 5x + 1

[tex]\Rightarrow\ x+5=\dfrac{2}{3}(5x+1)\\\\\Rightarrow\ 3(x+5)=2(5x+1)\\\\\Rightarrow\ 3x+15=10x+2\\\\\Rightarrow\ 10x-3x=15-2\\\\\Rightarrow\ 7x=13\\\\\Rightarrow\ x=\dfrac{13}{7}[/tex]

3(x - 4) = 3x - 12 (expand the brackets)
3x - 12 = 2x + 6
3x = 2x + 6 + 12 (put all of the integers on one side)
3x = 2x + 18 (simplify - collect like terms)
3x - 2x = 18 (put all of the unknowns on one side)
x = 18 (simplify - collect like terms)
