Answer:

x = 63°

y = 27°

Step-by-step explanation:

RECT is a rectangle.

By the property of interior angles of a polygon,

All interior angles of a rectangle measure 90°

m(∠RTC) = 90°

m(∠RTC) = m(∠RTE) + m(∠CTE) [Angle addition postulate]

x° + 27° = 90°

x = (90 - 27)°

x = 63°

Since, opposite sides of a rectangle are parallel and equal in measure,

RE║TC and TE is a transversal line,

m∠RET = m∠CTE [Alternate interior angles]

y = 27°

Step-by-step explanation:

Answer:

For #1, system of equations is 3m + 2c = 52, 4c + 3m = 68. m is the cost of one movie, c is the cost of one CD.  One CD costs $8, one movie costs $12.

For #2, The cost of one burger and one hotdog is b = 0.75, h = 0.90. 4 burgers would be $3, 4 hotdogs would be $3.60.

For #3 the answer is 19:30, Horatio has 30 games, Preston has 19.

Step-by-step explanation:

Yes, two sides are perpendicular, and the side lengths fit the Pythagorean theorem. The correct answer is option B.

A right triangle is a triangle in which one of the angles is at a right angle or two of the sides are perpendicular, or more formally, an orthogonal triangle, formerly known as a rectangle triangle.

In the given figure two sides are perpendicular, and the side lengths fit the Pythagorean theorem. the figure is a right-angled triangle.

Answer:

$63

Step-by-step explanation:

I believe you meant Richard worked for 7 hours and made $9 per hour.

In order to know how much Richard earned for 7 hours, you have to multiply Richard's salary rate with his number of working hours.

Therefore, Richard earned $63 for his 7-hour work.

Additional Information

Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.

Answer:

an = 115 + (n - 1) (-6)

a25 = - 29

Step-by-step explanation:

We use the definition for the nth term of an arithmetic sequence:

an = a1 + (n - 1) d

a5 = 91 = a1 + (5 - 1) d

91 = a1 + 4 d

a20 = 1 = a1 + (20 - 1) d = a1 + 19 d

1 = a1 + 19 d

now we subtract term by term one expression from the other

90 = 4 d - 19 d

90 = - 15 d

divide both sides by -15 to isolate d

d = 90 / (-15) = -6

Now we can calculate what a1 is using for example:

1 = a1 + 19 d

1 = a1 - 114

add 114 to both sides:

115 = a1

Then our general expression for the sequence is:

an = 115 + (n - 1) (-6)

We can now use it to calculate the value of a25:

a25 = 115 + (24) * (-6) = -29

Answer

The missing value is -14

Step-by-step explanation:

First you make a ratio or proportion: -4/6=x/21

Then you cross multiply

-4x21 which is -84 then 6 times x which is 6x  then the equation becomes 6x=-84

       from 6x you divide which becomes x=-84/6 which is -14

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."

Answer:

it is 4th one for 14 it is 2nd one

Step-by-step explanation:

The arc length is 3π/2 and the angle with terminal side in its fourth quadrant is 7π/6.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We need to find the arc length with the given information . centralangle = π/4, radius = 6

The formula for the arc length of a circle is given by:

Arc length = radius x central angle

In this case, the central angle is pi/4 and the radius is 6. Therefore, the arc length is:

Arc length = 6 x (π/4) = (3/2)π

Option D is correct, the arc length is 3π/2

An angle is said to be in the fourth quadrant if its terminal side lies in the fourth quadrant of the Cartesian plane, which is the quadrant below the x-axis and to the right of the y-axis.

Since the fourth quadrant is to the right of the y-axis, the angle must have a positive x-coordinate

3π/4 has its terminal side in the second quadrant, so it is not the answer.

π/3 has its terminal side in the first quadrant, so it is not the answer.

5π/3 has its terminal side in the third quadrant, so it is not the answer.

7π/6 has its terminal side in the fourth quadrant, so the answer is (d) 7π/6.

Therefore, the angle with terminal side in its fourth quadrant is 7π/6.

Answer:

$ 37.50

Step-by-step explanation:

We can rewrite this problem as: What is 6% of $625?

"Percent" or "%" means "out of 100" or "per 100",

Therefore 6% can be written as 6/100.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the sales tax we are looking for "t".

Putting this altogether we can write this equation and solve for t while keeping the equation balanced:

t=6100×$625

t=$3750100

t=$37.50

Answer:

40.50

Step-by-step explanation:

Sales price x sales tax rate = sales tax

675 x .06 (6%) = 40.50
