Answer:

m∠R

Step-by-step explanation:

Q is the inscribed angle formed by the interception of segments TQ and SQ

R is the inscribed angle formed by the interception of segments TR and SR

The inscribed angle theorem states that an angle inscribed in a circle is half of the central angle that subtends the same arc on the circle; then, both angles Q and R are half of the central angle and equal between them. Therefore, the angle does not change as its vertex is moved to different positions on the circle.

Answer:

3/16 cups

Step-by-step explanation:

Well, you see that 3/4 of a cup is 1 batch --->

3/4 cup  :  1 batch

to get 1/4 of a batch, you can just multiply both sides of the ratio by 1/4

3/4 * 1/4 cups : 1 * 1/4 batches

3/16 cups : 1/4 batches

Step-by-step explanation:

x = r cosΘ

y = r sinΘ

with r = 54 and Θ = 69°, thus

x = 54cos69° ≈ 19.4

y = 54sin69° ≈ 50.4

Thus (54, 69° ) as an ordered pair

Answer:

The new coordinates of the points of the line segment are p'(2,1) and q'(3,4)

Step-by-step explanation:

we know that

When you reflect a point across the line y= x, the x-coordinate and y-coordinate change places.

so

The rule of the reflection of a point across the line y=x is

(x,y) -----> (y,x)

we have

Points p(1,2) and q(4,3)

Applying the rule of the reflection across the line y=x

p(1,2) ------> p'(2,1)

q(4,3) -----> q'(3,4)

therefore

The new coordinates of the points of the line segment are p'(2,1) and q'(3,4)

Answer:

x= -7/8

Step-by-step explanation:

8x=-7

8x/8x = -7/8

Answer:

no solution

Step-by-step explanation:

use the box method to find out the factors

                 |         7      

     x^2      |

the top left and top right must multiply to 7x^2 and add up to 6x.

7 is multiplied together by 7 and 1, but only 7 and -1 can add up to 6x, so therefore there is no solution to this equation

another way is the quadratic equation

for an equation in form ax^2 +bx + c,

the quadratic equation states x = (-b + square root(b^2-4ac))/2a

in this case : x = -6 + (6^2 -28)^1/2 = -6+ (some negative root that doesn't exist)

so x = no solution

One way to tell if a relation is a function is by using something called the vertical line test. In other words, if we can draw a vertical that passes through more than one point on a graph, then the relation does not represent a function. Another way to tell if a relation represents a function is by looking at the X coordinates of each ordered pair. If any of the ordered pairs have the same X coordinate, then the relation is not a function.

Answer neither 8 nor 9 are prime!!!

Answer:

Because the sum of the measures of a pair of same-side interior angles

is equal to one-half the number of degrees in a parallelogram ⇒ B

Step-by-step explanation:

* Lets explain how to solve the problem

- In a parallelogram every two opposite sides are parallel

- In a parallelogram every tow opposite angles are equal

∵ The parallelogram is a quadrilateral

∵ The sum of the measures of the interior angles in any quadrilateral

   is 360°

∵ In parallelogram each two opposite angles are equal

∴ The sum of the measures of every two adjacent angles

   equal 360° ÷ 2 = 180°

* Lets solve the problem

- When parallel lines are cut by a transversal

∵ It is a fact that the parallel lines and their transversal can form a

  parallelogram

∵ The sum of the measures of the adjacent angles of the

   parallelogram is 180°

∵ The sum of the measures of the supplementary angles is 180°

∴ The same side-interior angles are supplementary, because

   they are two adjacent angles in a parallelogram

* Lets find the true statement

∵ The sum of the measures of every two adjacent interior angles

  in the parallelogram = 360° ÷ 2 = 180°

∵ 180° is half the sum of the measures of interior angles in the

  parallelogram

∴ Because the sum of the measures of a pair of same-side interior

  angles is equal to one-half the number of degrees in a

  parallelogram

Answer:

Addition.

Step-by-step explanation:

Multiplication is a faster way to do repeated addition.

For example, lets say you would add 10 fifteen's together. Addition would make it:

15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15

= 30 + 30 + 30 + 30 + 30

   = 60 + 60 + 30

      = 120 + 30

          = 150

However, when multiplying:

15 x 10 = 150

As you can tell, multiplication makes it so there are less steps, and is less time consuming.

Final answer:

To determine how many times 5/9 is greater than 4/15, we find a common denominator and compare the equivalent fractions. The fraction 5/9 is approximately 2.0833 times greater than 4/15.

Explanation:

The question is asking to find out how many times 5/9 is greater than 4/15. To compare these two fractions, we must find a common denominator or convert them to decimal form for easier comparison.

To find a common denominator, we can multiply the denominators 9 and 15 to get 135. Converting 5/9 to a fraction with 135 as the denominator, we get 75/135. Converting 4/15 to a fraction with 135 as the denominator, we get 36/135. Now, we compare the numerators 75 and 36, and we see that 75 is greater than 36.

Therefore, to find out how many times 5/9 is greater than 4/15, we divide 75 by 36, which gives us approximately 2.0833. Thus, 5/9 is about 2.0833 times greater than 4/15.

Answer:

2 hours and 44 mins

Step-by-step explanation:

Final answer:

Mary and her roommate can clean the apartment together in approximately 2.73 hours. This is calculated by adding their individual cleaning rates and then taking the reciprocal of the sum to find the total time.

Explanation:

The question asks how long it would take for Mary and her roommate to clean the apartment if they worked together. Mary can clean the apartment in 6 hours, which means in one hour, she can clean 1/6 of the apartment. Her roommate can clean the apartment in 5 hours, so in one hour, the roommate can clean 1/5 of the apartment. Working together, their combined cleaning rate per hour is 1/6 + 1/5. To find their combined rate, we get a common denominator, which is 30, so their rates become 5/30 and 6/30, respectively. Summing these, we get a combined rate of 11/30 of the apartment cleaned per hour. To find the amount of time it takes for them to clean the entire apartment together, we divide 1 by their combined rate, so 1 / (11/30) = 30/11 hours which is approximately 2.73 hours.

Answer:

Step-by-step explanation:

the expression cant be factored because there is no number that multiplies to get 16 but adds up to 9. ex; 8*2 is 16 but add to 10, 16 and 1 equals 17, and 4*4 is 16 but adds up to 8.

Answer:

your answer is d

Step-by-step explanation:

For x -

180 = 4x + 6 + 11x - 6

180 = 15x

[tex]\frac{180}{15}[/tex] = x

x = 12

For m∠ABD -

4(12) + 6

48 + 6

m∠ABD = 54

For m∠DBC -

11(12) - 6

132 - 6

m∠DBC = 126

Answer:

x = 12° ; m∠ABD= 54°    ; m∠DBC=126°

Step-by-step explanation:

∠ABD + ∠DBC = ∠ABC

Here ,

∠ABC is a straight line .

We know,

A straight angle is 180 degrees.

So,

∠ABD + ∠DBC = 180°

⇒(4x+6)° + (11x-6)° =180°                        [given]

⇒15x =180°

⇒x = (180/15)°      [divide both sides by 15]

∴ x = 12°

Now,

∠ABD = (4x+6)°         [given]

           ={(4 . 12) + 6 }°    

            =(48+6)°

            =54°  

And,

∠DBC = (11x-6)°                       [given]

           ={(11 .12)-6}°

           =(132 - 6)°

           =126°

To have $19,000 in 5 years with an 8% interest rate compounded semiannually, you should deposit approximately $12,840.72 now.

The question is about calculating the present value of an investment to reach a future sum of money with a given interest rate, compounded semiannually. To find out how much you should deposit now to have $19,000 in the future, we can use the formula for the present value of an investment for compound interest:

PV = FV / (1 + r/n)(nt)

FV = $19,000

r = 8% or 0.08

n = 2 (because interest is compounded semiannually)

t = 5 years

We can substitute these values into our formula:

PV = $19,000 / (1 + 0.08/2)(2*5)

Doing the math:

PV = $19,000 / (1 + 0.04)10

PV = $19,000 / 1.48024

PV = $12,840.72

So, you would need to deposit approximately $12,840.72 now in order to have $19,000 in 5 years, given an 8% interest rate compounded semiannually.

The solution to the absolute value equation 5[2x-4] + 1 = 11 is the solution set {1, 3}.

To solve the absolute value equation 5[2x-4] + 1 = 11, we first isolate the absolute value expression by subtracting 1 from both sides of the equation, resulting in 5[2x-4] = 10. Then we divide both sides by 5, yielding |2x - 4| = 2. Next, we consider the two cases where 2x - 4 equals 2 and where 2x - 4 equals -2.

For the first case, 2x - 4 = 2, we add 4 to both sides to get 2x = 6, and then divide by 2 to find that x = 3. For the second case, 2x - 4 = -2, we add 4 to both sides to get 2x = 2, and then divide by 2 to find that x = 1.

Thus, the solution set to the original equation is {1, 3}, and we can verify these solutions by substituting them back into the equation to check that they satisfy the initial condition.

Answer:

55.75

Step-by-step explanation:

First you start by doing what is in the parenthesis. so we divide 6 by 24 which gets us 0.25. Then we follow the rest of PEMDAS. Addition is next so we add 8 to 0.25 to get 8.25. Now we finally get to the fun part. 4 to the third power which is 64, then we subtract 8.25 to get 55.75. Hope that helps.

Answer:

2.13

Step-by-step explanation:

because 2.1349 is closer to 2.13 than 2.14 because the number 4 is less than 5 so it's closer to 0

When round a number to the nearest hundredth, digit in the thousandths place should be focused.

To round the number 2.1349 to the nearest hundredth, look at the digit in the thousandths place, which is 4 in this case.

When rounding to the nearest hundredth, consider the digit immediately to the right of the hundredth place, which is the digit in the thousandths place. In this case, 4 is less than 5.

1. Start with the number 2.1349 on a number line.

2. Look at the digit in the thousandths place (4). Since it's less than 5, we do not need to round up.

3. Therefore, 2.1349 rounded to the nearest hundredth is 2.13.

If it's 5 or greater, you round up; if it's less than 5, you leave the hundredths place unchanged. In this case, 4 is less than 5, so we round down to 2.13.
