Find the angle of the sector given the radius and the area of the sector.
Radius = 12 ft
Area of sector is 339.3 ft2
Answer:
270 degrees
Step-by-step explanation:
[tex]Area \: of \: the \: sector \\ \\ = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ 339.3 = \frac{ \theta}{360 \degree} \times 3.14 {(12)}^{2} \\ \\ 339.3 = \frac{ \theta}{360 \degree} \times 3.14 \times 144 \\ \\ \theta = \frac{339.3 \times 360 \degree}{3.14 \times 144} \\ \\ \theta = \frac{122,148\degree}{452.16} \\ \\ \theta= 270.143312 \degree \\ \\ \theta \approx \: 270\degree[/tex]
Between which two consecutive integers is each number located on a number line?
Answer:
< 0.99 <
Answer:
[tex]0 < 0.99 < 1[/tex]
Step-by-step explanation:
Given
[tex]Number = 0.99[/tex]
Required
Determine the interval which it belongs
The given number is less than 1
i.e.
[tex]0.99 < 1[/tex]
And it is greater than 0.
[tex]0.99 > 0[/tex]
So, the number is located between 0 and 1
i.e.
[tex]0 < 0.99 < 1[/tex]
When ringing up a customer, a cashier needs 10 seconds to process the payment as well as 5.7 seconds to scan each item being purchased. Write an equation that shows the relationship between the items being purchased, p, and the time, t.
Answer: 5.7p + 10
Step-by-step explanation:
From the question, we are given the information that when ringing up a customer, the cashier will need 10 seconds to process the payment and 5.7 seconds to scan every item that are purchased.
The equation that shows the relationship between the items being purchased, p, and the time, t will then be:
= 5.7p + 10
At a school. Number of boys:number of girls=11:9. There are 124 more boys than girl. Work out the total number of students at the school
Answer:
Total students = 1240
Step-by-step explanation:
Given that,
Number of boys: number of girls=11:9
[tex]\dfrac{x}{y}=\dfrac{11}{9}\\\\9x=11y[/tex] ......(1)
There are 124 more boys than girls i.e.
x = 124+y .....(2)
Put the value of x from equation (2) in equation (1). So,
9(124+y) = 11y
1116 +9y = 11y
1116 = 2y
y = 558
Put the value of y in equation (2).
x = 124+558
x = 682
Total students = x+y
= 682+558
= 1240
So, there are 1240 students at the school.

Answer:
678.4 cm^2
Step-by-step explanation:
total surface area of prism is equal to ph+2B where p represents the perimeter of the base, h the height of the prism and B the area of the base.
Firstly, we calculate the perimeter of the base. This is equal to 10 + 14 + 10 + 14, or 48.
Secondly, we must calculate the height of the prism, which is shown as 8.3.
Lastly, we must calculate the area of the base, which is 10 * 14, or 140.
We can now substitute these values into the formula, ph + 2B to find the total surface area of the prism:
ph + 2B,
(48)(8.3) + 2(140),
398.4 + 280,
678.4
This means that the total surface area of this prism is 678.4 cm^2

Denise earns $4,500 per month plus 4% commission on her sales. One month she had sales of $50,000. What were her total earnings? • a. $50,000 • b. $2,000 • c. $6,500
Answer:
$6500
Step-by-step explanation:
Given data
Monthly Earnings= $4500
Commission= 4%
Sales= $50000
Let us find the amount of the commission
=4/100*50000
=0.04*50000
= $2000
Since the monthly earning is $4500, hence the total earning is
=2000+4500
=$6500
Which expression represents the volume of the prism? One-halfx3 (one-half x) cubed Five-halvesx3 (Five-halves x) cubed
Answer:
Volume = ½x³ units.
Step-by-step explanation:
From the image, we can deduce the following;
Length = x
Breadth = x
Height = ½x
To find the volume of prism;
Mathematically, the volume of a prism is given by the formula;
Volume of prism = length * breadth * height
Substituting into the formula, we have;
Volume of prism = x * x * ½x
Volume = x² * ½x
Volume = ½x³ units

Step-by-step explanation:
= P [ 1-R/100 ] T
= 15000 [ 1-12/100] ⁵
= 15000 [100-12/100]⁵
= 15000 [0.88]⁵
= 15000 × 0.52773
= 7915.95..

-8 = 6 - 14
use the number line:
go to 6 on the number line and count back until you reach -8; you should count 14
since it's a -8 that means the bigger number also has to be negative. between 6 and 14, 14 is bigger so it becomes a negative number
so your answer is -14
An ellipse has foci located at (2,4) and (2,16) and vertices located at (2,0) and (2,20) this ellipse is vertical
Answer:
The equation of the ellipse is [tex]\frac{(x-2)^{2}}{8^{2}}+\frac{(y-10)^{2}}{10^{2}} = 1[/tex].
Step-by-step explanation:
The statement is incomplete, the most probable outcome may be the equation of the ellipse based on information given.
The equation of an ellipse whose major axis is vertical and is centered at a point different from origin is defined by:
[tex]\frac{(x-h)^{2}}{b^{2}} + \frac{(y-h)^{2}}{a^{2}} = 1[/tex] (1)
Where:
[tex](h,k)[/tex] - Coordinates of the center of the ellipse.
[tex](x,y)[/tex] - Coordinates of a point in the line of the ellipse.
[tex]a[/tex] - Length of the major semiaxis.
[tex]b[/tex] - Length of the minor semiaxis.
The coordinates of the center of the ellipse is midpoint of the segment between vertices, which are collinear with foci:
[tex](h,k) = \frac{1}{2}\cdot V_{1} (x,y) + \frac{1}{2}\cdot V_{2}(x,y)[/tex] (1)
Where [tex]V_{1} (x,y)[/tex] and [tex]V_{2} (x,y)[/tex] are the coordinates of the vertices.
If we know that [tex]V_{1} (x,y) = (2,0)[/tex] and [tex]V_{2} (x,y) = (2, 20)[/tex], then the coordinates of the center ellipse are:
[tex](h,k) = (2, 10)[/tex]
The length of the semimajor axis can be determined by using the following vectorial expression, which is equivalent to the Pythagorean Theorem:
[tex]a = \sqrt{[(h,k)-V_{1}(x,y)]\,\bullet\,[(h,k)-V_{1}(x,y)]}[/tex] (2)
If we know that [tex](h,k) = (2, 10)[/tex] and [tex]V_{1} (x,y) = (2,0)[/tex], then the length of the semimajor axis is:
[tex]a = \sqrt{(2-2)^{2}+(10-0)^{2}}[/tex]
[tex]a = 10[/tex]
And the length of the minor semiaxis is found by means of this Pythagorean identity:
[tex]b = \sqrt{a^{2}-c^{2}}[/tex] (3)
Where [tex]c[/tex] is the length between the center and any of the foci. This distance can be found by using this vectorial formula:
[tex]c = \sqrt{[(h,k)-F_{1}(x,y)]\,\bullet\,[(h,k)-F_{1}(x,y)]}[/tex] (4)
If we know that [tex](h,k) = (2, 10)[/tex] and [tex]F_{1} (x,y) = (2,4)[/tex], then the length between the center and any of the foci is:
[tex]c = \sqrt{(2-2)^{2}+(10-4)^{2}}[/tex]
[tex]c = 6[/tex]
And the length of the minor semiaxis is:
[tex]b = \sqrt{10^{2}-6^{2}}[/tex]
[tex]b = 8[/tex]
FInally, the equation of the ellipse is [tex]\frac{(x-2)^{2}}{8^{2}}+\frac{(y-10)^{2}}{10^{2}} = 1[/tex].

Answer:
all of these are right angled triangle. so u can use pythagoras theorem, h²=p²+b²
longest side is called hypotenious (h)
and u can assume any of the remaining side as p and b as your choice
eg=
1) h=13
p=12
b=?
using pythagrous theroem
h²=p²+b²
13²=12²+b²
169= 144+b²
169-144=b²
25=b²
25 is the square root of 5 so
5²=b²
square root of each side will be cancelled so
b = 5
In this way u can solve your questione.....
Answer:
1.
[tex] {h}^{2} = {p }^{2} + {b}^{2} [/tex]
[tex] {13}^{2} \: = {12}^{2} + {b}^{2} [/tex]
[tex] {b}^{2} = {13}^{2} - {12}^{2} [/tex]
[tex] {b }^{2} = 169 - 144[/tex]
[tex] {b}^{2} = 25/tex]
[tex]b = \sqrt{25} [/tex]
[tex]b = 5[/tex]

The surface area of a triangular prism is 18: square inches. What is the surface area of a similar solid that has been enlarged by a scale factor of 2.52?
Answer:
45.36 square inches
Step-by-step explanation:
Given the following
Surface area of a triangular prism = 18 square inches
If it is enlarged by a scale factor of 2.52, the area of the enlarged solid is expressed as;
Area of enlarged solid = area of original sold * scale factor
Area of enlarged solid = 18 * 2.52
Area of enlarged solid = 45.36 square inches
hence the surface area of a similar solid that has been enlarged by a scale factor of 2.52 is 45.36 square inches
Answer:45.36 square inches
