Answer:
244 degrees
Step-by-step explanation:
Since one angle APE is 90 degrees, that means line segments AD and BE are perpendicular bisectors.
Since both segments go through the center, that means all the angles are central angles.
Since angle APE is 90 degrees, that also means that angle EPD is 90 degrees.
33k -9 = 90
33k = 99
k = 3
Since we know k we can substitute it to find angle CPD.
20 k + 4 = 20*3 + 4= 60+4= 64 degrees.
Central angles equal angles of arcs, so we can and angles APE, EPD, and DPC to find the measure of major arc CAD.
64+ 90 +90 = 244 degrees
Aiden is grocery shopping and wants to know which packages are cheapest. He is
looking at four different bottles of liquid laundry detergent: Bottle A is 175 fluid
ounces for $19.25; Bottle B is 138 fluid ounces for $8.97; Bottle C is 100 fluid ounces
for $8.00; and Bottle D is 72 ounces for $7.56. Assuming the detergent is of equal
quality, which bottle is the best deal?
Answer:Bottle B
Step-by-step explanation:
Given
Bottle A has 175 fluid ounce and cost [tex]\$19.25[/tex]
So it cost [tex]\frac{175}{19.25}=9.09\ \text{ounce per}\ \$[/tex]
Bottle B has 138 fluid ounce and cost [tex]\$8.97[/tex]
So it cost [tex]\frac{138}{8.97}=15.38\ \text{ounce per}\ \$[/tex]
Bottle C has 100 fluid ounce and cost [tex]\$8.0[/tex]
So it cost [tex]\frac{100}{8}=12.5\ \text{ounce per}\ \$[/tex]
Bottle D has 72 fluid ounce and cost [tex]\$7.56[/tex]
So it cost [tex]\frac{72}{7.56}=9.52\ \text{ounce per}\ \$[/tex]
So, Bottle B delivers more ounces at same price
The rectangle below has an area of x^2-7x+10square meters and a width of x - 5 meters. What expression represents the length of the rectangle below? length=_____ meters.
Answer:
L = (x - 2) meters
Step-by-step explanation:
The area of the rectangle = (x² - 7x + 10) m²
The width = (x - 5) m
length = ?
Area of a rectangle = length × width
x² - 7x + 10 = L(x -5)
note L = length
divide both sides by (x-5)
(x² - 7x + 10)/(x - 5) = L
L = x² - 7x + 10 / (x -5)
Factorize x² - 7x + 10
find the numbers you can multiply to give you 10 and also add to give you -7
The numbers are -2 and -5. Therefore,
x² - 2x - 5x + 10 = 0
x(x - 2) - 5(x - 2) = 0
(x-5)(x-2) = 0
Let us go back to our division
L = x² - 7x + 10 / (x -5)
x² - 7x + 10 = (x-5)(x-2)
L = (x-5)(x-2) / (x -5)
L = (x - 2) meters

Elise is a project manager
In 2016 she earned a monthly salary of £2,100
in 2017 she had a 3% raise
Given that in 2017 Elise worked 42 hours per week for 45 weeks, work out her average pay per hour for the year
please help :(
Answer:
£11.85
Step-by-step explanation:
In the question, we are told that:
In 2016 she earned a monthly salary of £2,100
In 2017 she had a 3% raise
This means 3% of £2,100
3/100×£2,100 = £63
This means her salary for 2017 =
£63 + £2,100 =£2,163
Step 2
We are told in the question that she worked 42 hours per week for 45 weeks in 2017
Since her monthly pay for 2017 = £2,163
She worked 42 hours per week
There are 7 days in one week
The number of hours she worked per day = 42 hours ÷ 7 = 6 hours per day
4.345 weeks= 1 month
The number of hours she worked per month = 42 hours × 4.345 weeks
= 182.49 hours.
We can say that for 182.49 hours she was paid = £2,163
Her average pay per hour is calculated as:
If 182.49 hours = £2,163
1 hour = represented by Y
Cross multiply
182.49Y = £2,163
Y = £2,163 ÷ 182.49
Y = £11.852704258
Approximately = £11.85
Therefore, Elise Average pay per hour for the year = £11.85

Find m angle d for m angle b = 65
The figure is not drawn to scale
Answer:
Denote O as center of circle, draw OA, OC.
As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):
=> AOC + D = 180
Moreover, angle AOC = 2 x angle B = 2 x 65 = 130
=> D = 180 - 130 = 50 deg
Hope this helps!
:)
The measure of the angle d for m angle b = 65 in the figure of circle and quadrilateral is 50 degrees. Option A is correct.
What is a measure of angle?The measure of angle between the two points of a ray or line is the measure of rotation between these two points. The angles are measured in degrees or radians.
The figure given in the problem contained a circle and a quadrilateral.
In this figure, the measure of the angle b is,
[tex]m\angle d =65^o[/tex]
Here, the two tangent lines AD and DC cuts the circle at point A and C respectively.
Let the center of the circle is O. Thus the angle b is equal to the angle AOC by the tangent line theorem as,
[tex]\angle O =2m\angle b=130 ^o[/tex]
The sum of angle AOC and the angle D is equal to 180 degrees. Therefore,
[tex]\angle AOC+m\angle d=180\\130++m\angle d=180\\m\angle d=180-130\\m\angle d=50^o[/tex]
Hence, the measure of the angle d for m angle b = 65 in the figure of circle and quadrilateral is 50 degrees. Option A is correct.

Andrea uses 9.8 pints of blue paint to paint her bedroom walls. 2/5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
5.88 pints
Step-by-step explanation:
Well the amount of white paint is 3 / 5 of 9.8
0.6 * 9.8 = 5.88
Answer: 14.7 pints of white paint
IF two different colors were used.
IF she mixed paint to get a light blue, 3/5 of the total would be about 5.9 pints.
Step-by-step explanation:
If 9.8 is 2/5 of the total amount used, set up the equation as 9.8= 2x/5
You get the total amount of paint used is 24.5 pints. Subtract the 9.8 of blue to find the amount of white. That's 14.7 pints.
In practical, real life, a quart of paint covers about 100 square feet. That's an average 8 ft high by 12 ft wide wall.
So that is why I edited this answer. 24 pints is 3 gallons-- that is enough for 3 bedrooms.
And I wish that Math teachers used more common measurements of paint!

Maureen earned some money doing odd jobs last summer and put it in a savings account that earns 9% interest compounded quarterly. After 10 years, there is $300.00 in the account. How much did Maureen earn doing odd jobs?
Answer:
Maureen earned $123.19 doing odd jobs
Step-by-step explanation:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.
In this question:
Compounded quarterly means that [tex]n = 4[/tex]
10 years, so [tex]t = 10[/tex]
9% interest, so [tex]r = 0.09[/tex]
There is $300.00 in the account, which means that [tex]A = 300[/tex]
How much did Maureen earn doing odd jobs?
This is P.
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]300 = P(1 + \frac{0.09}{4})^{4*10}[/tex]
[tex](1.0225)^{40}P = 300[/tex]
[tex]P = \frac{300}{(1.0225)^{40}}[/tex]
[tex]P = 123.19[/tex]

What are the solutions to the equation x2 - 8x = 10
Answer:
x = 4 ±√26
Step-by-step explanation:
Please write this as x^2 - 8x = 10, or x^2 - 8x - 10 = 0. " ^ " indicates exponentiation.
Let's complete the square:
x^2 - 8 x can be rewritten as
x^2 - 8x + 16 - 16, and so
x^2 - 8x = 10 becomes x^2 - 8x + 16 - 16 - 10 = 0, or
(x - 4)^2 = 26
Taking the square root of both sides, we get:
x - 4 = ±√26, or
x = 4 ±√26
Line N passes through the points (-1,4) and (-1,-4)Which is true of line N?
Answer:
Line N is a vertical line with an undefined slope
Step-by-step explanation:
To find slope we do (y2-y1)/(x2-x1)
So we do that with (-1,4) and (-1,-4)
(-4-4)/(-1-(-1))
-8/0
Since the denominator is 0, that means the slope is undefined because you cannot divide by 0

The value of a car is $23,000. It loses 11% of its value every year. Find the approximate monthly decrease in value. Round your answer to the nearest tenth.
Answer:
$210.8 monthly.
Step-by-step explanation:
There are two ways to do this. You can either find out what 11% of $23,000 is by multiplying .11 by $23,000, then subtract this from $23,000 to find the yearly increase, where you can then divide by 12, or you can divide .11 by 12 and then multiply this by $23,000.

i need to find the value of x
Answer:
x = 24
Step-by-step explanation:
Since all the angles share a common vertex 'U' lying on a straight line QT.
Therefore, sum of all angles formed at U will be equal to 180°.
m∠RUQ + m∠RUS + m∠SUT = 180°
(2x - 4) + (3x + 5) + (2x + 11) = 180°
(2x + 3x + 2x) + (5 - 4 + 11) = 180
7x + 12 = 180
7x = 180 - 12
x = [tex]\frac{168}{7}[/tex]
x = 24
Therefore, value of x = 24
