2: A bag contains 5 black counters, 4 blue counters, and
1 white counter. A counter is taken from the bag at
random. Write down the probability that the counter
was blue.
Answer:
The probability that the counter was blue is [tex]\mathbf{\frac{2}{5}}[/tex]
Step-by-step explanation:
Number of black Counters = 5
Number of blue Counters = 4
Number of white Counters = 1
We need to write down the probability that the counter was blue.
First find Total Counters
Total Counters = Number of black Counters + Number of blue Counters + Number of white Counters
Total Counters = 5+4+1
Total Counters = 10
Now, we need to find probability that the counter taken was blue
The formula used is:
[tex]Probability= \frac{Number\:of\:favourable\:outcomes}{Total\:outcomes}[/tex]
There are 4 blue counters in the back, so Favourable outcomes = 4
[tex]Probability= \frac{Number\:of\:favourable\:outcomes}{Total\:outcomes}\\Probability= \frac{4}{10}\\Probability= \frac{2}{5}[/tex]
The probability that the counter was blue is [tex]\mathbf{\frac{2}{5}}[/tex]
Kenichi took $72 to a concert. If he paid for 5 tickets that each cost d dollars, how much did he still have left? Write an expression to represent the difference in cost with d dollars.
Answer:
The expression represents the difference is (72 - 5d) dollars
Step-by-step explanation:
Let us solve the question
∵ Kenichi took $72 to a concert
∴ The total money with him = 72 dollars
∵ He paid for 5 tickets that each cost d dollars
→ That means he bought 5 tickets each cost d dollars
∴ The cost of the tickets he paid = 5 × d
∴ The cost of the tickets he paid = 5d dollars
∵ The money left with him = total money he has - the amount he spent
∵ The total money = 72 dollars
∵ The amount he spent = 5d dollars
∴ The money left with him = 72 - 5d
∴ The expression represents the difference is (72 - 5d) dollars.

Perry's school is due west of his house and due south of his friend Sasha's house. The
distance between the school and Sasha's house is 6 miles and the straight-line distance
between Perry's house and Sasha's house is 10 miles. How far is Perry's house from school?
Answer:
8 miles
Step-by-step explanation:
You can think of it as a triangle, which will look like the picture at the bottom.
You're trying to find the missing length, and to do that you can use the Pythagorean theorem.
That would be:
[tex]6^{2} + x^{2} =10^{2}[/tex]
Then, solving:
[tex]36 + x^{2} =100\\x^{2} = 64\\x = 8[/tex]
Therefore, the answer is 8 miles
your going to build a 3 foot by 7 garden.if you want to surround it by a 1 foot wide brick border , how many square feet will you need

The number of square feet that you need to add will be 24 square feet.
What is the area of the rectangle?Let W be the rectangle's width and L its length.
The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be
Area of the rectangle = L×W square units
You're going to build 3 feet by 7 feet garden. If you want to surround it with a 1-foot wide brick border.
Then the area of the garden and border will be
A₁ = (3 + 2)(7 + 2)
A₁ = 5 x 9
A₁ = 45 square feet
The area of the garden will be
A₂ = 3 x 7
A₂ = 21 square feet
The number of square feet that you need to add will be
A = A₁ - A₂
A = 45 - 21
A = 24 square feet
The number of square feet that you need to add will be 24 square feet.

Solve 12(x - 2) + 3x = {(x + 12) + 10x
Answer:
x=9
Let's solve your equation step-by-step
12(x−2)+3x=x+12+10x
Step 1: Simplify both sides of the equation.
12(x−2)+3x=x+12+10x
(12)(x)+(12)(−2)+3x=x+12+10x(Distribute)
12x+−24+3x=x+12+10x
(12x+3x)+(−24)=(x+10x)+(12)(Combine Like Terms)
15x+−24=11x+12
15x−24=11x+12
Step 2: Subtract 11x from both sides.
15x−24−11x=11x+12−11x
4x−24=12
Step 3: Add 24 to both sides.
4x−24+24=12+24
4x=36
Step 4: Divide both sides by 4.
4x/4=36/4
x=9
Answer:
x=9
Answer: x = 9
Step-by-step explanation:
12(x − 2) + 3x = x + 12 + 10x
12(x - 2) + 3x = 11x + 12
12x - 24 + 3x = 11x + 12
15x - 24 = 11x + 12
15x = 11x + 12 + 24
15x = 11x + 36
15x - 11x = 36
4x = 36
x = 36/4
x = 9
use the multiplier method to decrease £56 by 14%
you must show your working.
Answer:
New value =
56 - Percentage decrease =
56 - (14% × 56) =
56 - 14% × 56 =
(1 - 14%) × 56 =
(100% - 14%) × 56 =
86% × 56 =
86 ÷ 100 × 56 =
86 × 56 ÷ 100 =
4,816 ÷ 100 =
48.16
56 decreased by 14% = 48.16
Absolute change (actual difference):

Which graph represents the equation 12 = 3x+ 4y? Explain how you know.
Graph A
Graph B
Graph C
Answer:
Step-by-step explanation:
3x%2B4y=12 Start with the given equation
4y=12-3x Subtract 3+x from both sides
4y=-3x%2B12 Rearrange the equation
y=%28-3x%2B12%29%2F%284%29 Divide both sides by 4
y=%28-3%2F4%29x%2B%2812%29%2F%284%29 Break up the fraction
y=%28-3%2F4%29x%2B3 Reduce
Looking at y=-%283%2F4%29x%2B3 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=-3%2F4 and the y-intercept is b=3
Since b=3 this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis
So we have one point
Now since the slope is comprised of the "rise" over the "run" this means
slope=rise%2Frun
Also, because the slope is -3%2F4, this means:
rise%2Frun=-3%2F4
which shows us that the rise is -3 and the run is 4. This means that to go from point to point, we can go down 3 and over 4
So starting at , go down 3 units
and to the right 4 units to get to the next point
Now draw a line through these points to graph y=-%283%2F4%29x%2B3
So this is the graph of y=-%283%2F4%29x%2B3 through the points and

Answer:
Total number of slices = 9 slices
Step-by-step explanation:
Given:
Diameter of a cake = 12 cm
Area of one slice = 4π cm²
Find:
Total number of slices
Computation:
Radius of cake = 12 / 2 = 6 cm
Area of circle = πr²
Area of circle = π(6)²
Area of circle = 36π cm²
Total number of slices = Area of circle / Area of one slice
Total number of slices = 36π / 4π
Total number of slices = 9 slices
Answer:
9 full slices

What is the approximate area of the circle shown below? 70 in diameter
A. 15,394 in^2
B. 220 in^2
c. 3848 in^2
D. 110 in^2
Answer:
c
Step-by-step explanation:
area is radius squared times pi(3.14) the radius is half of the diameter they give you the diameter so divide it by 2 to get the radius then multipy that by pi(3.14)
The approximate area of the circle of the given diameter of 70 inches will equal 3848 in². Hence, option C is correct.
What is the area?The area of an object is the amount of two-dimensional space it occupies. It is the measurement of the number of unit squares that completely encompass the surface of a compact figure. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.
As per the given values in the question,
Diameter of circle = 70 inches
Then, the radius of the circle will be.
r = 70/2
r = 35 in²
Use the formula of the area of a circle,
[tex]A =\pi\ r^{2}[/tex]
A = 3.14 × 35²
A = 3848 in².

Multiplication Property of EqualityDivision Property of EqualityAddition Property of EqualitySubtraction Property of EqualityAlgebra I
Terms/CoefficientsCoordinates (x, y)Solving systems of equations of using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
7x - y = 7
x + 2y = 6
Step 2: Rewrite Systems
Equation: x + 2y = 6
[Subtraction Property of Equality] Subtract 2y on both sides: x = 6 - 2yStep 3: Redefine Systems
7x - y = 7
x = 6 - 2y
Step 4: Solve for y
Substitution
Substitute in x: 7(6 - 2y) - y = 7Distribute 7: 42 - 14y - y = 7Combine like terms: 42 - 15y = 7[Subtraction Property of Equality] Subtract 42 on both sides: -15y = -35[Division Property of Equality] Divide -15 on both sides: y = 7/3Step 5: Solve for x
Define original equation: x + 2y = 6Substitute in y: x + 2(7/3) = 6Multiply: x + 14/3 = 6[Subtraction Property of Equality] Subtract 14/3 on both sides: x = 4/3
