A rectangle has a length of 5r - 6 and a width of 2r + 3. Find the area.
Answer:
[tex]10r^2+3r-18[/tex] sq. units
Step-by-step explanation:
The area of a rectangle is its length multiplied by its width, so in this case:
[tex]A=(5r-6)(2r+3)[/tex]
We can solve this using the distributive property to expand the right side, and then combine like terms to simplify:
[tex](5r-6)(2r+3)=\\=2r(5r-6)+3(5r-6)\\=10r^2-12r+15r-18\\=10r^2+3r-18[/tex]

A single card is drawn from a standed 52 card deck .Work out the probability of choosing a queen . Give your answer in its simplest form
Answer: 1/13
Step-by-step explanation:
There are 4 queens of the four different shapes in a standard 52 card deck.
The probability that one will pick a queen from a single draw is therefore:
= 4/52
Take it to its simplest form by dividing both sides by 4:
= 1/13
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 ?
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]

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

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

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?
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

Answer:
x=4
Step-by-step explanation:
Alright so for this one the following angles are corresponding meaning that the two equations are equal to each other. Knowing that you then have to set up an equation and the equation is 25x=4+24x. Now you wanna get the variable and the constant on different sides. To do this you subtract 24 from each side to get 1x=4. Then you divide each side by 1 to get x=4

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
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
