Diameter of a circle = 28 m
Then, radius of the circle will be :
[tex] = \tt \frac{diameter}{2} [/tex]
[tex] =\tt \frac{28}{2} [/tex]
[tex] = \tt14 \: m[/tex]
Thus, the radius of this circle = 14 m
Area of circle :
[tex] = \tt\pi {} {r}^{2} [/tex]
[tex] =\tt 3.14 \times 14 \times 14[/tex]
[tex] = \tt3.14 \times 196[/tex]
[tex] = \tt615.44 \: {m}^{2} [/tex]
Thus, the area of this circle = 615.44 m²
Circumference of circle :
[tex] = \tt2\pi r[/tex]
[tex] =\tt 2 \times 3.14 \times 14[/tex]
[tex] = \tt87.92 \: m[/tex]
The circumference of this circle = 87.92 m
Therefore, the area of this circle = 615.44m² and the circumference of this circle = 87.92m

PLEASE ANSWER:)
Answer:
y = -5x - 5
Step-by-step explanation:
to get the coefficient of the 'x' term (which is the slope) you take the difference of the y-values [5 - (-5)] divided by the difference of the x-values (-2 - 0)
so slope = 10/-2 or -5/1
to get the -5, this is the point at which the line intersects the y-axis; from looking at the graph you can see this is -5

Which ratio is expressed as a unit rate?
A $1.00/$1.00lb
B 1page /3min
C 16in./16sec
D 67miles/60min
Answer:
Option A.
Step-by-step explanation:
The question asked for a unit rate. This means that there should be no denominator higher than 1. Option A is the only one which have a denominator of 1.
Reason 1. M∠A + m∠B + m∠C = 1. 2. 28° + x − 4° + = 180° 2. Substitution 3. X = 3. Algebra
Answer:
156°
Step-by-step explanation:
Reason 1.
M∠A + m∠B + m∠C = 1.
2.
28° + x − 4° + = 180°
We collect like terms
x = 180° + 4° - 28°
x = 156°

Heyy mate..!Step-by-step explanation:
ᴛʜᴇ sʟᴏᴘᴇ=2/3ᴛʜᴇ ʏ ɪɴᴛᴇʀᴄᴇᴘᴛ= -12: 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]

Luciahas$40,000inasavingsaccountthatearns14%annually.Theinterestisnotcompounded.Howmuchinterestwillsheearnin4years? Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years. $
Answer:
$22,400.
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 14%/100 = 0.14 per year,
then, solving our equation
I = 40000 × 0.14 × 4 = 22400
I = $ 22,400.00
The simple interest accumulated
on a principal of $ 40,000.00
at a rate of 14% per year
for 4 years is $ 22,400.00.
The table shows the cost of a sandwich and a drink at a local cafeteria. how much more does a sandwich cost than a drink
Answer:
$2.02
Step-by-step explanation:
1.50/2 = 0.75
0.75 - 0.49 = 0.26
Sandwich = 2(0.75)+1.5 = 3
Drink = (0.49) + 0.49 = 0.98
3 - 0.98 = 2.02

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

A recycle center received 7.2 tons of glass, 8,500 pounds of paper, and 5/8 ton of aluminum. If 2,000 pounds = 1 ton, approximately what was the total amount of recyclable material received at the center?
Answer:
7.2 X 2000 = 14400 pounds
5/8 = 0.625, 0.625 X 2000 = 1250 pounds
14400 + 1250 + 8500 = 24150 pounds
24150/2000 = 12.08 tons

hurry
Answer:
24x / 5y
Step-by-step explanation:
Given :
24x² / 5xy
24x² = 24 * x * x
5xy = 5 * x * y
Hence,
24x² / 5xy = (24 * x * x) / (5 * x * y)
= (24 * x) / (5 * y)
= 24x / 5y

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

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):
48.16 - 56 = - 7.84

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
