Answer:
x = 5/8 plz give branliest
Step-by-step explanation:
Using the equation,[tex]1 = \frac{1}{8} + x + \frac{2}{8}[/tex]
simplify 1 = x + [tex]\frac{3}{8}[/tex]
1 - [tex]\frac{3}{8}[/tex] = x
[tex]\frac{5}{8}[/tex] = x
Answer:
x = 5/8 or 0.625
Step-by-step explanation:
Rewrite the equation as 18+x+28=118+x+28=1.
18+x+28=118+x+28=1
Simplify 18+x+2818+x+28.

A circle has a central angle that measures 23º and the arc length is 12pi. Find the measure of the radius in radians. Round answers to nearest hundredth.
Answer:
The radius of the circle is 93.91
Step-by-step explanation:
In order to calculate the radius of this circle we can apply the formula to find the arc length. This formula is shown below:
length = [(angle)*pi*radius]/180
Since we want to find the radius we can isolate that variable, as shown:
(angle)*pi*radius = length*180
radius = (length*180)/(angle*pi)
radius = (12*pi*180)/(23*pi) = (12*180)/23
radius = 93.91
A grocery store finds that the number of boxes of a new cereal sold increases each week. In the 1st week, only 20 boxes of the cereal were sold. In the 2nd week, 53 boxes of the cereal were sold and in the 3rd week 86 boxes of the cereal were sold. The number of boxes of cereal sold each week represents an arithmetic sequence.
what is the explicit rule for the arithmetic sequence that defines the number of boxes of cereal sold in week n?
Use this rule to calculate how many boxes of cereal will be sold during the 7th week.
Answer:
218 boxes of cereal
Step-by-step explanation:
To get the explicit rule, find the difference between each week:
53-20 = 33
86-53 = 33
The explicit rule is:
aₓ = 33x - 13
or
f(x) = 33x - 13
If you use this rule, you can plug in 7 for x and you get:
218 boxes of cereal
15) Solve. −x2 = 2x − 15 A) x = 3, x = 5 B) x = −3, x = 5 C) x = 3, x = −5 D) x = −3, x = −5
Answer:
x=-5 x=3
Step-by-step explanation:
−x2 = 2x − 15
Add x^2 to each side
x^2−x2 =x^2+ 2x − 15
0 = x^2+ 2x − 15
Factor
What two numbers multiply to -15 and add to 2
5*-3 = -15
5-3 =2
(x+5) (x-3) =0
Using the zero product property
x+5 =0 x-3=0
x+5-5=0-5 x-3+3=0+3
x=-5 x=3

Triangle ABC was translated according to the rule (x, y) = (x + 1.5, y-3.5) to create the image AA'B'C' shown on the
coordinate plane
Which graph shows the pre-image, ABC?
Answer:
Option D
Step-by-step explanation:
Hope this helps! :)
The coordinates of the preimage will be at A(-2.5, 5.5), B(-2.5, 2.5) and C (-6.5, 2.5)
What is translation?Translation is a transformation technique for changing the size and position of an object on the x-y plane.
From the given diagram, the coordinate A'B'C' is given as:
A' = (-1, 2)
B' = (-1, -1)
C' = (-5, -1)
If the triangle ABC was translated according to the rule (x, y) = (x + 1.5, y-3.5) to create the image A'B'C'
A (x + 1.5, y-3.5) = (-1, 2)
x + 1.5 = -1
x = -2.5
y - 3.5 = 2
y = 5.5
Hence A = (-2.5, 5.5)
B = (x + 1.5, y-3.5) = (-1, -1)
x + 1.5 = -1
x = -2.5
y - 3.5 = -1
y = 2.5
Hence B = (-2.5, 2.5)
C (x + 1.5, y-3.5) = (-5, -1)
x + 1.5 = -5
x = -6.5
y - 3.5 = -1
y = 2.5
Hence C = (-6.5, 2.5)
Hence the graph that shows the pre image ABC is attached below

Answer:
They are not congruent
Step-by-step explanation:
In the circle below, diameter CD is perpendicular to chord AB as shown. Radii OB and OA are drawn.
(a) How could we prove that OEB is congruent to OEA? Explain.
(b) What does your answer tell you must be true about segments AE and BE ? Why?
(c) If the diameter of circle O is 20 and CE 4, then determine the length of AB . Show how you arrived at your answer.
Answer:
The length of AB is 16 units.Step-by-step explanation:
(a)We know that [tex]\angle OEB = 90\°[/tex], by given, so it's a right angle, by definition.
[tex]\angle OEA[/tex] and [tex]\angle OEB[/tex] are adjacent angles on a straight angles. That means they are sumplementary angles by definition.
[tex]\angle OEA + \angle OEB = 180\°\\ \angle OEA = 180\° -90\°\\\angle OEA = 90\°[/tex]
Therefore, [tex]\angle OEA = \angle OEB[/tex].
(b)Sides AE and BE are congruent, because the congruence between those right angles, and the congruence between the other corresponding sides justify the congruence between sides AE and BE.
Notice that the hypothenuses of each right triangle are congruent, because they are also radius of the circle, which means they are congruent by definition.
Additionally, side OE is a common leg for both right triangles.
Therefore, sides AE and BE are congruent.
(c)We know that [tex]d=20[/tex] and [tex]CE=4[/tex], that means the radius is
[tex]r=\frac{d}{2}=\frac{20}{2}=10[/tex]
Notice that the chord AB is formed by AE and BE by sum of segments.
We know the hypothenuses are equal to 10 units of length, because they are radius.
Additionally,
[tex]OC=OE+EC[/tex], by sum of segments.
[tex]10=OE+4\\OE=10-4\\OE=6[/tex]
Which means the common leg is 6 units long.
Now, we use the Pythagorean's theorem to find the missing leg
[tex]OB^{2}=EB^{2}+OE^{2}\\ 10^{2}=EB^{2}+6^{2}\\100-36=EB^{2}\\EB=\sqrt{64}\\ EB=8[/tex]
But, [tex]AB=AE+EB[/tex], by sum of segments.
[tex]AB=8+8=16[/tex], because [tex]AE=EB[/tex] we said before.
Therefore, the length of AB is 16 units.

O
- $0.50
O $300.00
O $9.50
O - $9.50
Answer:
negative - $9.50
Step-by-step explanation:
The expected value of a ticket of the local fire company given the price and the expected values is $-9.50.
What is the expected value?
The expected value is the sum of the prizes added to the cost.
Expected value = value of the prizes - cost
(300 + 150 + 50 + 0) - (10 x 1000)
500 - 10,000
- 9500
Expected value of a ticket = - 9500 / 1000 = -9.50
