Answer:
x = 10
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides of the equation:
x - 4 (+4) = 6 (+4)
x = 6 + 4
x = 10
x = 10 is your answer.
~
You get this result after adding 4 to both sides. This is to undo the "minus 4" happening to the x.
To check the answer, replace x with 10 and simplify each side like so
x-4 = 6
10-4 = 6
6 = 6
We get the same thing on both sides, so that confirms the solution.
What is the measure of o?
4 cm
e
12 cm
O A. 4 radians
O B. 3s radians
O c. 3 radians
O D. 4radians
plss helppp
==============================================
Work Shown:
L = arc length = 12 cmtheta = angle in radians = unknownr = radius = 4 cmL = theta*r
12 = theta*4
12/4 = theta
3 = theta
theta = 3 radians, choice C is the answer.
--------
Side note: The formula L = theta*r only works if theta is in radians.
If theta is in degrees, then use L = (theta/360)*2pi*r. So you can see that radian mode is much easier in this case.
Pleas help me if this is correct
Answer:
yes, i think it is
Step-by-step explanation:
Answer:
Yes...your right...but no...its 28 degrees.
Step-by-step explanation:
So bascially, angle C is 90 degrees. So is angle D.
We know A is 28 degrees.
We know a tiangle is 180 degrees.
We dont know the degree of C in the first trinagle or the secodn triangle, but again, we know the total degrees of C is 90.
To find the missing angle, we must find what C is first.
So, we know we can subtract 90 from 180 to get 90. Since there is a 90 degree angle in the first triangle.
Next we can subtract 28, since we know that is the measure of angle A.
This gets us 62.
Now subtract 62 from the 90 degrees of angle C. THis will find us its angle in the second traingle.
This gets us 28.
This is our missing number.
So you were wrong in the sense that you solved for the wrong angle y, but you did get the right answer:
Since we know that a triangle is 180, and one of these is a right angle, there is 90 degrees.
If we subtracrt the 28 we got just now, we would get 62, which is angle B, or DBC.
However, the 28 is angle C, or DCB.
So your answer is actually 28, not 62.

A sphere used in a contest has a
diameter of 9 feet. What is the
volume of the sphere?
Answer:
382 ft³ (3 s.f.)
Step-by-step explanation:
[tex]\boxed{volume \: of \: sphere = \frac{4}{ 3}\pi {r}^{3} }[/tex]
Radius= diameter ÷2
Rdaius of sphere
= 9 ÷2
= 4.5 ft
Volume of sphere
[tex] = \frac{4}{3} (\pi)(4.5)^{3} [/tex]
= 382 ft³ (3 s.f.)
Josh lit a 14 in candle. She noticed that it wad getting an inch shorter every 30 minutes. Write an equation in y=mx+b form to medel this situation. Let x be the number of hours and y be the total height of the candle
Answer:
y = -1/30x + 14
Step-by-step explanation:
Height (changing by -1) is the dependent variable, therefore is represented by y
Time (changing by +30) is the independent variable, therefore is represented by x
14 = where we started from
Slope = Change in y / Change in x
Slope = -1/30x
Equation = -1/30x + 14

Ethan and Sam work at different department stores. Ethan is paid 125$ per week and an 8% commission on sales, while Sam is paid 200$ per week and a 6% commission on sales. Enter the amount in dollars of sales for which they earn the same weekly income
Answer:
3750$
Step-by-step explanation:
Let x be the amount in dollars of sales:
125 + 0.08x = 200 + 0.06x (when Ethan and Sam earn the same weekly income)
0.02x = 75
x = 3750

Shawn wants to buy a bowling ball that typically costs $120. Currently, the bowling ball is on sale for 13% off. As a member of the bowling league, Shawn is also entitled to an additional 15% discount off the sale price of the bowling ball. If the sales tax in Shawn's state is 7.5%, what is the final price that Shawn will have to pay for the bowling ball?
Answer:
95.40
Step-by-step explanation:
120x.13=15.60. discount
120-15.60=104.40 sales price
104.40x.15=15.66 additional discount
104.40-15.66=88.74 additional sales price
88.74x.075=6.66 sales tax
88.74+6.66=95.40 total price

Write the equation of the line, in slope-intercept form y=mx+b, that has a slope of 9 and a y-intercept of -3.
Step-by-step explanation:
We are supposed to write the equation in slope intercept form of a line . Firstly we know the slope intercept form as ,
[tex]\implies\sf y = mx + c [/tex]
Where ,
m is the slope c is the y Intercept .Now by question , the given data is ,
m = 9 c = -3On substituting the respective values we have ,
[tex]\sf\implies y = 3 * x + (-3)\\\\\sf\implies\red{ y = 3x - 3 } [/tex]
Hence the slope intercept form is y = 3x - 3 .
Suki rode her bike 6/7 mile. Claire rode her bike 1/3 mile. They want to compare how far they each rode their bikes using benchmark 1/2. Select the correct answer to describe how to solve the problem.
Answer:
6/7 > 1/2
1/3 < 1/2
Suki rode her bike a longer distance than Clarie
Step-by-step explanation:
Suki's distance = 6/7 miles
Compare with bechmark 1/2
6/7 and 1/2
Make the denominators same
(6*2)/(7*2) and (1*7)/(2*7)
12/14 and 7/14
12/14 is greater than 7/14
12/14 > 7/14
Therefore, 6/7 > 1/2
Clarie distance = 1/3 miles
Compare with bechmark 1/2
1/3 and 1/2
Make the denominators same
(1*2)/(3*2) and (1*3)/(2*3)
2/6 and 3/6
2/6 is less than 3/6
2/6 < 3/6
Therefore,
1/3 < 1/2
Compare Suki's distance with Clarie
compare 6/7 and 1/3
Make the denominators same
(6 * 3)/(7 * 3) and (1 * 7)/(3 * 7)
18/21 and 7/21
18/21 > 7/21
Suki rode her bike a longer distance than Clarie

Look at the graph below.
Which point can you add to the graph to make this graph NOT A
FUNCTION?
(2,6)
(5.3)
(7.5)
(8,8)
Answer:
B. (5, 3)Step-by-step explanation:
Given points:
(3, 5), (5, 8), (9, 7)The graph should have a same x-value with a different y-value.
From the list we have only point (5, 3) which makes this a non-functional relationship.
Correct choice is B
Points here are
(3,5)(5,8)(9,7)As per definition of function
Every domain has a unique rangeCheck option B
If we put than
The. f(5) would have 2 values 8 and 3

what is the chancr of rolling a 7 or a 9 on two dice .
Answer:
5/18 0r 27.77%
Step-by-step explanation:
I am assuming both are six-sided and have numbers 1-6 on each of the six sides. There are 36 possible roll combinations. Of the 36, four result in 9 and six result in 7. Therefore there is a 10/36 chance of rolling a 7 or a 9. That can be simplified however by dividing by two on both numbers. That equals 5/18. As a percent you would divide 5 by 18 and get 0.2777. After that you multiply 0.2777 by 100 to get 27.77%.

Answer:
One of the legs is missing; the leg missing is 16 inches long
Step-by-step explanation:
Hypotenuse is usually the longest leg and you'll because it's directly across the biggest angle (the biggest angle is the right angle so Leg C would be the biggest leg).
20² - 12² = x²
400 - 144 = x
400 - 144 = 256
√256 = 16
what should be subtracted from (1/2+1/3+1/4) to get -2
1/2 + 1/3 + 1/4 - x = - 2
6/12 + 4/12 + 3/12 - x = - 2
6 + 4 + 3 / 12 - x = - 2
13/12 - x = - 2
x = 13/12 + 2
x = 13/12 + 24/12
x = 37/12 Or x = 3 1/12
Answer:
x = 37/12 Or x = 3 1/12
Step-by-step explanation:
1/2 + 1/3 + 1/4 - x = - 2
6/12 + 4/12 + 3/12 - x = - 2
6 + 4 + 3 / 12 - x = - 2
13/12 - x = - 2
x = 13/12 + 2
x = 13/12 + 24/12
x = 37/12 Or x = 3 1/12
