How do I find the radius of a circle

Answers

Answer: 17

Step-by-step explanation: To find the radius of Q, you'd have to solve for x. So, 4x+3=7x-6, which results in x equaling 3. Next, bisect the chord EF, so it will be 8. Solve for QA, which is 15 and use the pythagorean theorem to solve: x^2=15^2+8^2 -> x=17

If the interest earned is $25 and the principal is $500 and the interest rate is 5%, what is the time?

Formula = simple interest= principal times annual interest rate times the time in years

Answers

Final answer:

To find out how long it takes to earn $25 in interest on a principal of $500 at a 5% annual interest rate, use the simple interest formula. The calculation reveals it takes 1 year.

Explanation:

The question asks us to determine the time it takes to earn $25 in interest on a principal of $500 at an annual interest rate of 5% using simple interest. The formula for simple interest is Interest = Principal × Rate × Time. We can rearrange this formula to solve for time (Time = Interest / (Principal × Rate)).

Given that the interest earned is $25, the principal is $500, and the rate is 5% (0.05 in decimal form), we substitute these values into our rearranged formula to find the time.

Interest = $25Principal = $500Rate = 5% or 0.05

Substituting these into the formula gives us:

Time = $25 / ($500 × 0.05) = $25 / $25 = 1 year

Therefore, it takes 1 year to earn $25 in interest at a 5% annual rate on a $500 principal using simple interest.

A rectangle has one side that measures 10 units and another side that measures 4 units.Circle the two measurement units that show the length and width of another rectangle with the same perimeter.

4 units 5units

8 units 3 units

9units 7 units

Answers

Answer:

None of the above

Step-by-step explanation:

10 + 10 + 4 + 4 = 28

First choice

4 + 4 + 5 + 5 = 18 X

Second choice

8 + 8 + 3 + 3 = 22 X

Third choice

9 + 9 + 7 + 7 = 32 X

Therefore there is none that are the same.

Answer:

None of the above.

Step-by-step explanation:

A rectangle has one side that measures = 10 units

the another side that measures = 4 units

Perimeter = 2( Length + width )

Perimeter of this rectangle = 2( 10 + 4 )

                                             = 2(14) = 28 units

We have to find the same measurement units that shows the same perimeter.

1. 4 units 5 units

Perimeter = 2( 4 + 5 ) = 2 × 9 = 18 units

2. 8 units 3 units

Perimeter = 2( 8 + 3 ) = 2 × 11 = 22 units

3. 9 units 7 units

Perimeter = 2( 9 + 7 ) = 2 × 16 = 32 units

There are no another rectangle with the same perimeter.

Given: circle k(O), m FE =56°, FD=ED, m∠EFD=76°
Find: m∠EFO

Answers

Based on the inscribed isosceles triangle shown below, the measure of angle EFO is 62°.

In Euclidean Geometry, the measure of an intercepted arc is equal to the central angle of a circle. Based on the information provided above, the measure of arc FE is equal to 56°, so the measure of the central angle FOE must be equal to 56°.

By critically observing triangle FOE, we can logically deduce that it is an isosceles triangle with base FE because segments FO and EO represent the radii of circle O.

Since an isosceles triangle comprises two (2) side lengths that are equal and two (2) base interior angles that are congruent, we have:

FD = ED

m∠EFO ≅ m∠FEO

By applying triangle sum property to triangle FOE, we have;

m∠EFO + m∠FEO + mFE = 180°

2m∠EFO + m∠FE = 180°

2m∠EFO + 56° = 180°

m∠EFO = (180° - 56)/2

m∠EFO = 62°

Complete Question:

Given: circle k(O), m FE =56°, FD=ED, m∠EFD=76°

The value of 9 2/3-4 1/5 number is 5 7/15 .

To find the value of 9 2/3 - 4 1/5, we first need to convert each mixed number into an improper fraction. For 9 2/3, the improper fraction is (9 × 3 + 2)/3 = 29/3. For 4 1/5, the improper fraction is (4 × 5 + 1)/5 = 21/5.

Next, we need to find a common denominator to subtract these fractions. The least common multiple of 3 and 5 is 15, so we convert each fraction to have this common denominator. The first fraction becomes (29/3) × (5/5) = 145/15, and the second fraction becomes (21/5) × (3/3) = 63/15.

Now we can subtract the second fraction from the first: 145/15 - 63/15 = (145 - 63)/15 = 82/15. To convert this back into a mixed number, we divide 82 by 15 to get 5 with a remainder of 7, so the mixed number is 5 7/15.

Therefore, the answer is 5 7/15.

Which is the best estimate for the average rate of change for the quadratic function graph on the interval 0 ≤ x ≤ 4?
A) −1
B) −2
C) −3
D) −4

Answers

ANSWER

A) -1

EXPLANATION

The average rate of change of the given quadratic function on the interval 0 ≤ x ≤4 is the slope of the secant line connecting the points (0,f(0)) and (4,f(4)).

That is the average rate of change is:

[tex] = \frac{f(4) - f(0)}{4 - 0} [/tex]

From the graph, f(0) is 0 and f(4) is -4.

We plug in these values to obtain;

[tex] = \frac{ - 4 - 0}{4 - 0} [/tex]

This simplifies to;

[tex] = \frac{ - 4}{4} [/tex]

[tex] = - 1[/tex]

Hence the average rate of change for the given quadratic function whose graph is shown on 0≤x≤4 is -1

Connor is earning money by mowing lawns over the summer. The amount of profit he makes from mowing x lawns is modeled by the function p(x)=20x-75. What is the most appropriate domain of the function? A. All rational numbers B.all non-negative rational numbers c. All integers d. All non-negative integers

Answers

Answer:

Try D

Step-by-step explanation:

The numbers should always be whole, and if you're profiting, you'll never lose money. It should always be a positive number. Hopefully this helps! Good luck

Profit function have domain as set of all non-negative number thus domain of the profit function p(x)=20x-75 will be all non-negative integers so option (D) will be correct.

What is the range and domain of a function?

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

Given the profit function,

p(x)=20x-75

The graph of this function has been shown below which is representing the domain as (∞,∞) but in the our profit function x is the number of lawns that mowing so it will be a whole number and positive number.

Since domain is the set of all x's value thus it will be domain of the function.

Domian → [0,∞).

Hence "Domain of the profit function p(x)=20x-75 will be all non-negative".

What is 14 5/6 + 18 2/9 ? Express your answer in lowest terms.


plz answer quickly will give brainliest

Answers

Answer:

it is 32 and 7 over 15

Step-by-step explanation:

because when u add 14 and 18 u get 32 and then you add your numerator and your denimator so u will see that it is 32 and 7 over 15

The sum of 14 5/6 and 18 2/9 is 33 1/18, after adding the whole numbers and fractions separately and simplifying.

To find the sum of 14 5/6 and 18 2/9, we must first add the whole numbers and then the fractions separately. The whole numbers add up to 14 + 18, which is 32. To add the fractions 5/6 and 2/9, we need a common denominator, which is 54. Now converting the fractions we get (45/54) + (12/54). Adding these gives us 57/54, which is equal to 1 3/54 or reduced to its lowest terms, 1 1/18. Adding this to the sum of the whole numbers we get 32 + 1 1/18, which equals 33 1/18.

Answer:

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠TRQ is an external angle and ∠RTS, ∠RST are interior angles, hence

45x = 25x + 57 + x

45x = 26x + 57 ( subtract 26x from both sides )

19x = 57 ( divide both sides by 19 )

x = 3

Answer:

x = 3

Step-by-step explanation:

We are given expression for measure of angles of two corners of a triangle, while for the third corner, we know the exterior angle.

We know that the sum of all three angles of a triangle is 180°.

So we can write it as:

[tex] 2 5 x + ( 5 7 + x ) + ( 1 8 0 - 4 5 x ) = 180 [/tex]
