Answer:
148°
Step-by-step explanation:
The external angle at E is half the difference of the measures of arcs FD and FC.
(CF -44°)/2 = 52°
CF -44° = 104° . . . . multiply by 2
CF = 148° . . . . . . . . add 44°
The measure of arc CF is 148°.
Six times a number is 14 less than the opposite of that number. What is the number?
Answer:
2
Step-by-step explanation:
6 x 2 = 12
12 is less than 14
Question :
Six times a number is 14 less than the opposite of that number. What is the number?Solution :
Let's assume the number as " x "
According to the question :
Six times a number is 14 less than the opposite of that number.We already assumed that the number is x. So, opposite of the number would be -x.
[tex]\qquad \sf \: { \dashrightarrow 6x= - x-14}
[/tex]
Now, let's solve this equation :
[tex]\qquad \sf \: { \dashrightarrow 6x + x= -14}
[/tex]
Combining the like terms :
[tex]\qquad \sf \: { \dashrightarrow 7x = - 14}
[/tex]
Then divide both sides by 7 :
[tex]\qquad \sf \: { \dashrightarrow \dfrac{7x}{7} = - \dfrac{14}{7} }
[/tex]
[tex]\qquad \sf \therefore \: \bf{{ x= -2}}
[/tex]
Therefore, the required number is -2 .

The junior class sold boxes of pecans at $6 each and boxes of peanuts at $5 each. They sold a total of 82 boxes for $440. How many boxes of pecans and peanuts did they sell?
I NEED THE EQUATIONS...I can get the number of pecans and peanuts..I just need the equation to find them..please help me
This is Algebra
Answer:
Following are the required equations
[tex]x +y=84[/tex]
[tex]6x +5y=440[/tex]
Step-by-step explanation:
Let x boxes of pecans and y boxes of peanuts sold.
Total no of boxes sold = 84
[tex]\implies x +y=84[/tex]
Cost of one box of pecan =$6
So, cost of x boxes of pecans =$6x
Cost of one box of peanuts = $5
So, cost of y boxes of peanuts =$5y
Total sales = $440
[tex]\implies 6x +5y=440[/tex]
Niah earns $7. 25 per hour at her part-time job that she works at 18 hours per week. To earn some extra money, Niah helps her friend out with her dog walking service. It is possible to walk more than one dog at a time, and Niah’s friend pays her $9 per dog for each half hour walked. Niah walks dogs on 3 different days this week, as listed below. What is the total amount of earnings Niah had this week? Monday: 3 dogs for 0. 5 hours Wednesday: 2 dogs for 0. 5 hours and 1 dog for 0. 5 hours Thursday: 2 dogs for 1 hour a. $175. 50 b. $195. 75 c. $202. 50 d. $220. 50.
Answer:
The answer is D.
Step-by-step explanation:
The job would give her $130.50 dollars per week. Basically m= 7.25h.
Then, Monday was $27 dollars. Wednesday was $27 as well. Thursday was $36 also. So, we just needed to add this all together. You would get $220.50. So, it would be D!

The formula for the volume of a prism is V=Bxh, where B is the base area and h is the height.
Since we know that the volume is equivalent to 48 cubic feet, and the base area is 16 square feet.
We can divide the volume by the base to find the height of the crate.

How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For the given case, it is specified that:
Total number of employed writers and authors: 153,000Some college experience but no degree : 12.4%Bachelor's degree or higher : 84.1%Let we have:
writers and authors with bachelor’s degree = N + writers and authors with some college experience and no degree
(so the number of writers and authors with bachelor’s degree is N more than writers and authors with some college experience but no degree)
Number of writers and authors with bachelor's degree = 12.4% of 153000
which is [tex]\dfrac{153000}{100} \times 12.4 = 18972[/tex]
Number of writers and authors with some college experience but no degree = 84.1% of 153,000 which is [tex]\dfrac{153000}{100} \times 84.1 = 128673[/tex]
Thus,
128,673 = N + 18972
or
N = 128,673 - 18972= 109,701
Thus,
Number of Writers and authors with bachelor's degree more than those with only some college experience and no degree is Option b: 109701

what is the equation of a vertical line that passes through (3, -10)
[tex]\qquad \qquad\huge \underline{\boxed{\sf Answer}}[/tex]
A vertical line is always parallel to y - axis, I.e the x - coordinates of the points on the line never changes
Therefore, the equation of the line will be ~
[tex]\qquad \sf \dashrightarrow \: x = 3[/tex]
And on this line, for each value of y, there is same value of x ~
The required equation of a vertical line that passes through (3, -10) is x = 3
Equation of a lineThe equation of a line in point slipe form is expressed as:
y - y1 = m(x-x1)
The equation of a vertical line is given as x = a
The value of a is the x coordinate of the given point. Hence the value of a = 3

Use the sine tool to graph the function. The first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.
Answer:
Step-by-step explanation: i took the test.
The first point is ta x= - 3.
The function h(x) has a maximum value.
The graph of the function h(x) is given below.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
h(x) = 2 sin(2x) - 3
The first point is at x = -3.
h'(x) = 4 cos(2x)
h''(x) = -8 sin(2x)
This means,
h(x) has a maximum value on the graph.
The graph of h(x) is given below.
Thus,
h(x) has a maximum value and the graph is given below.

Use 3. 14 for Pi. 88 ft 100 ft 176 ft 201 ft.
There is 201 feet of fencing are needed to go around the pool path.
Given
A circular swimming pool has a radius of 28 ft.
There is a path all the way around the pool that is 4 ft wide.
A fence is going to be built around the outside edge of the pool path.
A circle has a radius of 28 feet.
A larger circle goes around the smaller circle that is 4 feet wide.
Circumference;For the length of the fence, we need to find the circumference of the outside of the pool path.
The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.
= 28 + 4 = 32 feet
The radius is then equal to 32 feet.
The circumference of the outer edge of the pool path would be equal to the perimeter;
[tex]\rm Perimeter = 2\pi r[/tex]
Where r is the radius.
Substitute all the values in the formula;
[tex]\rm Perimeter = 2\pi r\\\\\rm Perimeter = 2\times 3.14 \times 32\\\\Perimeter = 201[/tex]
Hence, there is 201 feet of fencing are needed to go around the pool path.

The scatter plot shows the number of minutes people had to wait for service at a restaurant and the number of staff available at the time.
A line that models the data is given by the equation $$, where $$ represents the wait time, and represents the number of staff available.
The slope of the line is -1.62. What does this mean in this situation?
it means that the scatter plots are off the chart
Is a slope of 1.62 realistic in this context?
no because it is not a coordinate and there isn't any decimals in the wait time
The $$-intercept is $$. What does this mean in this situation?
it means there's more waiting time
Is a $$-intercept of $$ realistic in this context?
no because when you try to find it it goes off the graph and isnt calculable.
Edit my response f
