Find the radius of the circle below. Round your answer to the nearest tenth.
Answer:
5.8 cm
Step-by-step explanation:
Area of the shaded sector of the circle = 31.2 cm²
Angle (θ) of the minor sector = 360 - 256 = 104°
Are of sector of a circle is given as, θ/360*πr²
Therefore:
[tex] \frac{104}{360}*3.142*r^2 = 31.2 [/tex]
[tex] 0.29*3.142*r^2 = 31.2 [/tex]
[tex] 0.91*r^2 = 31.2 [/tex]
Divide both sides by 0.91
[tex] \frac{0.91*r^2}{0.91} = \frac{31.2}{0.91} [/tex]
[tex] r^2 = \frac{31.2}{0.91} [/tex]
[tex] r^2 = 34.286 [/tex]
[tex] r = \sqrt{34.286} [/tex]
[tex] r = 5.8 [/tex] (nearest tenth)
Instructions: Find the measure of the indicated angle to the
nearest degree
Answer:
I would think it is 45° (Sorry if it turns out I'm wrong)
Step-by-step explanation:
We know that one corner is already 90 degrees so we can take 180 and subtract 90 from it which gets us 90. The other two angles are equal so we take 90 and divide it by 2. This gets us 45°.
Answer:
? = 46
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hypotenuse
sin ? = 38 / 53
Take the inverse sin of each side
sin ^-1 ( sin ?) = sin ^-1 ( 38/53)
? = sin ^-1 ( 38/53)
? =45.80579628
To the nearest degree
? = 46

Find the value of (525)² - (475² using sutible identite
Answer:
Step-by-step explanation:
a² - b² = (a +b)(a - b)
a = 525 & b = 475
525² - 475² = (525 + 475) (525 - 475)
=1000 * 50
= 50,000
The value of (525)² - (475)² using the identity (a²- b²) = (a+b) (a-b) is 50000.
The expression given is:
(525)² - (475)²
The above expression looks similar to the expression (a²- b²).
What is the simplified form of expression (a²- b²)?The simplified form of the expression (a²- b²) is (a+b) (a-b).
So, (525)² - (475)² can be written as:
(525)² - (475)² = (525+475) (525-475)
(525)² - (475)² = 1000 * 50
(525)² - (475)² = 50000
Therefore, the value of (525)² - (475)² using the identity (a²- b²) = (a+b) (a-b) is 50000.

The cost of tea varies directly with the mass. Liz bought 4.5kg of tea for $10.35. What is the cost of 12kg of tea?
Answer:
$ 27.6.
Step-by-step explanation:
Let the cost of tea be C.
Let the mass of tea be M
From the question given, we were told that the cost of tea varies directly with the mass. This can be expressed as:
C & M
C = KM
K is called constant of proportionality.
C is the cost of the tea.
M is the mass of tea.
Next, we shall determine the constant of proportionality, K.
Cost (C) = $ 10.35
Mass (M) = 4.5 kg
Constant (K) =..?
C = KM
10.35 = K × 4.5
Divide both side by 4.5
K = 10.35/4.5
K = 2.3
Finally, we shall determine the cost of 12kg of tea as follow:
Mass (M) = 12 kg
Constant (K) = 2.3
Cost (C) =..?
C = KM
C = 2.3 × 12
C = $ 27.6
Therefore, the cost of 12 Kg of tea is $ 27.6
Answer:
$27.6
Step-by-step explanation:
10.35 divided by 4.5 = 2.3
$2.3 for 1 kg
2.3 times 12= 27.6

Correct question :
There is a bag with only red marbles and blue marbles. The probability of randomly choosing a red marble is 7 9 . There are 28 red marbles in the bag and each is equally likely to be chosen. Work out how many marbles in total there must be.
Answer:
Total number of marbles = 36
Step-by-step explanation:
Marbles in bag: Red and Blue only
Probability of randomly choosing a red marble = 7/9
Number of red marbles = 28
Total number of marbles in the bag =?
Probability = required outcome / Total possible outcomes
P(red marble) = required outcome (number of red marbles) / Total possible outcomes(total number of marbles
7/9 = 28 / total number of marbles
Total number of marbles * 7/9 = 28
Total number of marbles = 28 ÷ 7/9
Total number of marbles = 28 * (9/7)
= 252 / 7
Total number of marbles = 36

Type your response in the box. Why do many log functions (those that aren’t transformed in any manner except for a change in the base) have the point (1,0) in common? For example, all of these functions pass through (1,0): f(x) = ln x g(x) = log x h(x) = log2 x
Answer:
The point (1,0) is common to all log functions of the form k(x) = logb x with any base (b). Logarithmic functions share this feature because of a property of exponents that states b0 = 1 for any value of b.
In a log function of the form k(x) = logb x, k(1) = logb 1.
So, by the definition of a logarithm, bk(1) = 1.
Applying the property of exponents to bk(1) = 1 = b0, we get k(1) = 0.
So, (1,0) is a point on the graph.

. The value of a lottery prize doubles
each week until there is a winner. If
the prize is $1000 the first week,
write a recursive function rule and an
explicit function rule to model the
value of the prize P, in dollars, after t
weeks without a winner. (14.2)
Answer: P(t) = $1000*2^t
Step-by-step explanation:
Ok, we know that in the week 1 the price is: p = $1000
After one week, the price doubles, so here we have: p = 2*$1000
After another week, the price doubles again, here the price is:
p = 2*(2*$1000) = $1000*2^2
Here we already can see the relation, for each week, we multiply the previous price by two, which will increase the exponent in the two by 1 unit.
Then, for week number t, the price will be:
P(t) = $1000*2^t

A polygon PQSR is shown with vertex P on ordered pair 9, 6, vertex Q on ordered pair 3, 6, vertex S on ordered pair 3, 3 and vertex R on ordered pair 6, 3. Which set of transformations was performed on PQSR to form P'Q'S'R'? A dilation factor of 2 A dilation factor of 1 over 3 A dilation factor of 1 over 2 A dilation factor of 3
Answer:
Dilation factor of 3
Step-by-step explanation:
First you wil want to find out the the coordinates for each of the shapes:
Regular:
P =9,6
Q =3,6
R =6,3
S =3,3
Prime notation:
P' =3,2
Q' =1,2
R' =2,1
S' =1,1
Then using great old common sense in the picture you will see 3 units go down to 1 unit which will indicate Dilation factor of 3 as the answer!
Hope this helps!
Answer:
The Dilation of the polygon would be 3
Step-by-step explanation:
The reason the answer shall be three is because if you look at both polygons and then look at their angles you should come to notice that the angle coordinates for the polygon that has been used for dilation multiplied by 3 would be congruent to the dilated shape, so in short look at lets say... the top right angle of both polygons, look at both of them and multiply the shape that has not been dilated and multiply that top right angle by whatever equals the dilated shapes angle value, for example (3,3)x3 = (9,9), thus the answer would be that the dilation is equal to 3.

Step-by-step explanation:
In a trapezium the lower base angle is supplementary to the upper bas angle on the same side, thus
4x + 91 - 9x + 59 = 180, that is
- 5x + 150 = 180 ( subtract 150 from both sides )
- 5x = 30 ( divide both sides by - 5 )
x = - 6
Thus
∠ N = - 9x + 59 = - 9(- 6) + 59 = 54 + 59 = 113°
∠ K = 4x + 91 = 4(- 6) + 91 = - 24 + 91 = 67°
