Answer:
a = ±sqrt(3)
Step-by-step explanation:
a×a×a=a+a+a
Simplifying each side
a^3 = 3a
Divide each side by a
a^3 /a = 3a/a
a^2 = 3
Take the square root of each side
sqrt(a^2) = ±sqrt(3)
a = ±sqrt(3)
Answer:
nope its not equal
a×a×a=a³, but a+a+a=3a
so, a³≠3a

Please help me with circle theorems
Answer:
x = 38°, y = 68°, z = 55°
Step-by-step explanation:
This would be easier to explain if the vertices were labelled , however
Angles at the circumference of the circle subtended on the same arc are congruent.
x and 38 are subtended on the same arc
y and 68 are subtended on the same arc
z and 55 are subtended on the same arc
Thus
x = 38°, y = 68° and z = 55°
Given lines p and q are parallel, find the value of x that makes each diagram true.
Answer: for a the answer is 140° and for b x=25°
Step-by-step explanation:
for a, when you have 2 parallel lines cut by a transversal,the corresponding angles are congruent. and the angle140 is congruent to the corresponding angle as they are vertical angles are congruent.
for b, angle x is congruent to the angle that is supplementary to 155 therefore 180-155=25°

Line b has a slope of
Line c is parallel to line b. What is the slope of line c?
Answer:
[tex]\frac{-5}{9}[/tex]
Step-by-step explanation:
The slope of two parallel lines is the same. As long as the y-intercept is different then, the lines are parallel. Therefore, if the slope of line b is [tex]\frac{-5}{9}[/tex] then the slope of line c must also be [tex]\frac{-5}{9}[/tex].
In ΔCDE, \text{m}\angle C = (5x+18)^{\circ}m∠C=(5x+18) ∘ , \text{m}\angle D = (3x+2)^{\circ}m∠D=(3x+2) ∘ , and \text{m}\angle E = (x+16)^{\circ}m∠E=(x+16) ∘ . Find \text{m}\angle D.M∠D.
Answer:
Angle D = m∠D= 50°
Step-by-step explanation:
In ΔCDE we are given: 3 angles
m∠C=(5x+18) ∘
m∠D=(3x+2) ∘
m∠E=(x+16) ∘ .
The sum of angles in a triangle = 180°
Hence:
m∠C + m∠D + m∠E = 180°
(5x+18)° + (3x+2)° + (x+16)° = 180°
5x + 18 + 3x + 2 + x + 16 = 180°
5x + 3x + x + 18 + 2 + 16 = 180°
9x +36= 180°
Subtract 36 from both sides
9x + 36 - 36 = 180° - 36°
9x = 144°
x = 144°/9
x = 16
From the above question, we are asked to find:angle D (m∠D )
Hence:
m∠D=(3x+2)°
m∠D=( 3 × 16 + 2)°
m∠D=(48 + 2)°
m∠D= 50°

Complete one inequality to support Roger's claim and one to show that he is incorrect.
PLSSSSSSSSS HELp
Answer: [tex]0.1x-0.25y<0[/tex]
Step-by-step explanation:
Let the two numbers be x and y
10% of the first number will be;
10% of x
[tex]=\frac{10}{100} of x[/tex]
[tex]=0.1x[/tex]
25% of the other number will be ;
25% of y
[tex]0.25y[/tex]
If 10% of the first number is less than 25% of the other number, this is expressed as;
[tex]0.1x<0.25y[/tex]
[tex]0.1x-0.25y<0[/tex]
Hence the required inequality is [tex]0.1x-0.25y<0[/tex]

Find the measure of the numbered angle.
m∠5 =
Answer:
40°
Step-by-step explanation:
180- (90 + 40) = 50°
Angle 1 = 50°
180 - 50 = 130°
Angle 2 = 130°
180 - 130 = 50°
Angle 3 = 50°
180 - (90 + 50) = 40°
Angle 5 = 40°
OR
the two triangles are similar. Therefore, their angles are congruent. Since the tringle was only flipped and made slightly smaller, angles 9 and 5 are corresponding angles. (Both have the same measure of 40°)

Answer:
Measure of DE is 12
Step-by-step explanation:
Here, we want to get the measure of DE
We have two similar triangles here
BDE and BAC
if two triangles are similar, then the ratio of their sides are same
Thus, in this case, we proceed as follows;
Now, since DE cuts each side into half;
we can have AB as 2y; then BD as y
Thus, we have that;
BD/DE = AB/AC
y/4x + 4 = 2y/x + 36
2y(4x + 4) = y(x + 36)
2(4x + 4) = x + 36
8x + 8 = x + 36
8x-x = 36-8
7x = 28
x = 28/7
x = 4
recall;
DE is 4x + 4
insert x = 2
DE = 4(2) + 4
DE = 12

Marsha is changing her phone
service. One data package charges
an initial fee of $50 and $13.25 per
month. The other has no initial fee
but charges $25.75 per month for
the same data package. After how
many months would Marsha have
paid the same amount for either
data package?
Someone help me plz quickly
month 4: 13.25*4=53. 53+50 = 103
month 4: 25.75*4 = 103
They both cost $103 on month 4
Nadeen bought a magazine for $7.50 and two sandwiches that cost the same price. She spent a total of $20. How much did each sandwich cost?
Answer:
Each sandwich cost $6.25
Step-by-step explanation:
Subtract the price of magazine then divide the remaining amount with 2 since the price of sandwiches same
(20 - 7.5) ÷ 2 = 6.25
the ratio of the number of left-handed batters in a team to the number of right -handed batters was 5 : 8 there were 45 left-handed batters .
\
a) how many right-handed batters were there?
b) find the ratio of the number of left- handed batters to the total number of batters express youe=r answer in simplest form
Answer:
72 right handed batters.
Step-by-step explanation:
45/5=9
8*9=72
45:72=5:8
Hope this helps.
Answer:
a) 72 right-handed batters
b) 5:13
Step-by-step explanation:
This is the answer because:
1) For problem a, we can see that 5 x 9 = 45. In order to balance the ratio, we also have to mulitply the 8 with a 9:
8 x 9 = 72
Therefore, the answer is 72 right-handed batters.
2) For b, there are two ways to do it. Sine we know that there are 5 left-handed batters, we just add 5 + 8 = 13. Therefore, the simplest form of the ratio is 5:13. Another we can do it is by adding 45 + 72 = 117 (total batters). Then, 45 of them are left-handed batters which means the ratio is 45:117 = 5:13.
Therefore, the answer is 5:13.
Hope this helps! :D

Given f(x) = -3x + 3, solve for x when f(x) = 9.
Answer:
x = -2
Step-by-step explanation:
f(x) = -3x + 3
f(x) = 9
-3x + 3 = 9
Subtract 3 from both sides;
-3x = 6
Divide both sides by -3
x = -2

What is software?Software is a set of instructions for a computer to follow. The entirety of a computer system's programs, procedures, and routines are referred to as software. The term was developed to distinguish these instructions from hardware—for example, a computer system's physical components. A software program is a set of instructions that tell a computer's hardware how to do something.
System software and application software are the two most common types of software. A computer's internal operation is primarily controlled by an operating system, but system software also controls monitors, printers, and storage devices.
Given Software on computer is taking a long time to load,
There are a few simple solutions for programs that take a long time to open:
