Hello, a Maths question if anyone knows what to do Solve: 6(x+4)=30
Answer:
x = 1
Step-by-step explanation:
6(x+4)=30 (divide both sides by 6)
(x+4) = 30/6
x+4 = 5 (subtract 4 from both sides)
x = 5 - 4
x = 1
Step-by-step explanation: 6(x+4)=30
(Distributive property): 6x+24=30
( Transposition method): 6x=30-24( + becomes -) 6x=6
(Transpose 6 to rhs) x=6/6( since it was multiplication on LHS it becomes division in RHS) x=1

A cylinder with a diameter of 8 inches and height of 12 inches.Ross is wrapping a gift. The package is shaped like the cylinder shown. What is the least amount of paper he needs to cover the entire cylinder? Use 3.14 for Pi.401.92 in.2602.88 in.31004.8 in.22411.52 in.3
Answer:
The answer is A.
Step-by-step explanation:
We need to find the least amount of paper needed to wrap the entire cylinder. Therefore, we simply need to find the surface area of the cylinder.
Recall the formula for the surface area of a cylinder:
[tex]SA=2\pi r^2+2\pi rh[/tex]
We know the diameter is eight inches, so the radius is four inches. We also know the height is 12. Using 3.14 for π, substitute:
[tex]SA=2(3.14)(4)^2+2(3.14)(4)(12)[/tex]
[tex]SA\approx 401.92\text{ in}^2[/tex]
Our answer is A.

The slope-intercept form of the equation of a line that passes through point (–3, 8) is y =- 2 /3x +8 . What is the point-slope form of the equation for this line? y – 3 = –2/3 (x + 8) y + 3 = -2/3 (x - 8) y + 8 = - 2/3 (x - 3) y - 8 = -2/3 (x + 3 )
Answer:
y - 8 = - [tex]\frac{2}{3}[/tex](x + 3)
Step-by-step explanation:
y = - [tex]\frac{2}{3}[/tex] x + 8 ← is in slope- intercept form with slope m = - [tex]\frac{2}{3}[/tex]
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - [tex]\frac{2}{3}[/tex] and (a, b) = (- 3, 8), thus
y - 8 = - [tex]\frac{2}{3}[/tex] (x - (- 3)), that is
y - 8 = - [tex]\frac{2}{3}[/tex] (x + 3)

Nina can ride her bike 63,360 feet in 3,400 seconds, and Sophia can ride her bike 10 miles in 1 hour. What is Nina's rate in miles per hour if there are 5,280 feet in a mile?
Which girl bikes faster?
Answer:
12.7 mi/h (Nina's rate), so Nina's bike is faster.
Step-by-step explanation:
1 h = 60 min = 3600 sec
63360 ft/3400 sec *3600 sec/1 h * 1mi/5280ft =12.7 mi/h (Nina's rate)
12.9mi/h >10mi/h, so Nina is faster.

Trevor drew lines of best fit for two scatter plots, as shown. Which statement describes the placement of the lines Trevor drew?
Answer:
A)Only Line A is well placed line of best fit
Step-by-step explanation:
Best fit line :A line through a scatter plot of data points that best expresses the relationship between those points is called best fit line
The least-squares method provides the closest relationship between the dependent and independent variables by minimizing the distance between the residuals and the line of best fit
By considering both the given graphs
We can see that Line A gives the minimum distance between residuals and line of best fit whereas Line B does not give the minimum distance between residuals and line of best fit
So,Option A is true
A)Only Line A is well placed line of best fit
Answer: a) only line A is a well placed line of best fit

Find the equation of the line passing through the points (8,-16) and (1,5)
Answer:
y = -3x + 8
Step-by-step explanation:
First, find the slope using rise/run
21/-7
= -3
Then, find the y-intercept by using the slope and by plugging in a point
5 = -3(1) + b
5 = -3 + b
8 = b
So, the equation will be:
y = -3x + 8
Hey there! :)
Answer:
y = -3x + 8.
Step-by-step explanation:
Use the slope formula to solve for the slope:
[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Plug in the coordinates:
[tex]m = \frac{-16-5}{8 - 1}[/tex]
Simplify:
[tex]m = \frac{-21}{7}[/tex]
m = -3.
Plug in the x and y value, along with the slope into the slope-intercept formula (y = mx + b) to solve for b:
5 = -3(1) + b
5 = -3 + b
b = 8.
Rewrite the equation:
y = -3x + 8.

Matrix tossed three coines wat is the probability that all three coins will land on the same side
Answer: 1/4
Step-by-step explanation:
This problem is very interesting, because it does not specify which side the coin must land on. Thus, the first flip has a 100% of landing on one side, then the next two have a 50% chance of landing on the same side. Thus, the probability is 1*.5*.5, or .25, or 1/4

24 athletes threw the shot put at a track and field meet. If this was 15/100 of all the athletes in the meet, how many athletes competed in the meet total?
Answer:
160 athletes
Step-by-step explanation:
Let the total number of athletes in the meet be x
Given that 24 athletes who threw the shot put at a track and field meet are 15/100 of all the athletes in the meet .
If we write this in mathematical algebraic expression
15/100 of all the athletes in the meet = 24
15/100 * x = 24
=> x = 24*100/15 = 24*100/3*5 = 160
Thus, 160 athletes competed in the meet.
Suppose that Upper X has a discrete uniform distribution f left-parenthesis x right-parenthesis equals StartLayout left-brace1st Row 1st Column 1 divided by 3, 2nd Column x equals 1,2,3 2nd Row 1st Column 0, 2nd Column otherwise EndLayout A random sample of n equals 39 is selected from this population. Find the probability that the sample mean is greater than 2.1 but less than 2.6. Express the final answer to four decimal places (e.g. 0.9876). The probability is
Answer:
The probability that the sample mean is greater than 2.1 but less than 2.6 is 0.2236.
Step-by-step explanation:
The random variable X follows a discrete uniform distribution.
The probability mass function of X is:
[tex]f(x)=\left \{ {{\frac{1}{3}};\ x=1,2,3 \atop {0;\ \text{otherwise}}} \right.[/tex]
Then,
a = 1
b = 3
The mean and standard deviation of the random variable X are:
[tex]\mu=\frac{b+a}{2}=\frac{3+1}{2}=2\\\\\sigma=\sqrt{\frac{(b-a+1)^{2}-1}{12}}=\sqrt{\frac{(3-1+1)^{2}-1}{12}}=0.8165[/tex]
The sample size is, n = 39.
According to the Central Limit Theorem if we have an unknown population with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from the population with replacement, then the distribution of the sample mean will be approximately normally distributed.
Then, the mean of the sample means is given by,
[tex]\mu_{\bar x}=\mu[/tex]
And the standard deviation of the sample means is given by,
[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]
As n = 39 > 30, the sampling distribution of sample mean of X will follow a Normal distribution approximately.
Compute the probability that the sample mean is greater than 2.1 but less than 2.6 as follows:
[tex]P(2.1<\bar X<2.6)=P(\frac{2.1-2.0}{0.8165/\sqrt{39}}<\frac{\bar X-\mu_{\bar x}}{\sigma/\sqrt{n}}<\frac{2.6-2.0}{0.8165/\sqrt{39}})[/tex]
[tex]=P(0.76<Z<4.59)\\\\=P(Z<4.59)-P(Z<0.76)\\\\=1-0.77637\\\\=0.22363\\\\\approx 0.2236[/tex]
Thus, the probability that the sample mean is greater than 2.1 but less than 2.6 is 0.2236.
If Milly has 29924827134702 candies and she gave 928439 to BOB then he gave 1000 back to Milly How much does both Milly and BoB have?

Answer:
939.41711
Step-by-step explanation:
using the pythagorean theorem we can find the hypotenuse of a right angle triangle by using a^2 +b^2 = c^2
a and b being the legs of the triangle.
in this case a = 400
and b = 850
square both numbers:
160000 + 722500 = 882500
√882500 = 939.41711
Raise -2 to the double of b and divide the result by the quadruple of a. A=-4 and B =+3.
Answer: - 4
Step-by-step explanation:
Given that A = - 4, B = 3
According to the instruction :
Raise -2 to the double of b and divide the result by the quadruple of a. A=-4 and B =+3
Raise - 2 to the double of b ;
Result = (-2)^(2*3) = (-2)^6 = 64
Divide result by quadruple of a
a = - 4 ;
Quadruple of 'a' means 4 times as many as 'a' = '4 * a' quadruple of a = (-4) * 4 = - 16
= (-2)^6 / -16
64 / - 16
64 / - 16 = - 4
I really need help on this one! Giving brainliest, Need two answers!
Step-by-step explanation:
first question:From the graph we notice that the minimum of the function 1 is -1
From the table we notice that the minimum of the second function is 2
so the function #2 has a greater minimum
second question :The function is x²+3x-4
Derivate it and solve the equation y'=0
y'= 2x+3
y'=0
2x+3=0
2x= -3
x = -3/2
Derivate it again:
y"= 2> 0⇒ so the function reaches the minimum at -3/2
the image of -3/2 is :
y= (-3/2)²+3*(-3/2)-4 = -6.25
so the answer is

Find the vertex of the function given below y=x^2-2x+1
Hey there! :)
Answer:
(1, 0).
Step-by-step explanation:
Convert from standard form to vertex form by completing the square:
y = x² - 2x + 1
Move 1 to the other side:
-1 = x² - 2x
Complete the square. Remember to add to both sides:
-1 + (1) = x² -2x + 1
Simplify:
0 = (x - 1)²
The function in vertex form is:
y = (x - 1)²
Therefore, the vertex is:
(1, 0).

what is the coefficient of x^2 y^3 in the expansion of (2x+y)^5
If it's x²y³ then we know it's the second term of the expansion, that known we can use the combination
C(5, 2) = 5!/(2!.3!) = 10
Then if we had something like
(a + b)^5 our second term would be 10a²b³ but as we can see it's "a²"
And in our case we have 2x as a
So we must do 2² too
2² = 4
10 . 4 = 40
Then our second term of the expansion would be
40x²y³
Cone W has a radius of 8 cm and a height of 5 cm. Square pyramid X has the same base area and height as cone W. Paul and Manuel disagree on how the volumes of cone W and square pyramid X are related. Examine their arguments. Which statement explains whose argument is correct and why?
This question is incomplete because it lacks the appropriate attachment containing the argument of Paul and Manuel
Kindly find attached the appropriate attachment necessary to solve this question.
The attachment was sourced online
Answer:
a) Paul's argument is correct, Manuel used the wrong formula to find the volume of square pyramid X
Step-by-step explanation:
From the above question, we are given two shapes: Cone W and Square Pyramid
Cone W: Radius = 8cm, Height = 5cm
Volume of a Cone = 1/3 πr²h
Where π = 3.14
Volume of Cone X = 1/3 × 3.14 × 8² × 5
= 334.93cm³
For Square pyramid X
Volume = 1/3 × Base Area × Height
Base Area of Cone W = Base Area of square pyramid X = πr²
Where π = 3.14
Base area = 3.14 × 8² = 200.96cm²
Height of Square pyramid X = Height of Cone W = 5cm
Volume of Square pyramid = 1/3 ×200.96cm² × 5cm
= 334.93cm³
Therefore, from my above calculation and compared with the arguments of Paul and Manuel, Option a) "Paul's argument is correct, Manuel used the wrong formula to find the volume of square pyramid X" is the correct option.
The reason why is because the correct formula for the volume of a square pyramid = 1/3 × Base area × Height
This was the formula Paul used.
Manuel on the other hand used the formula: Base Area × Height to find the volume of cone W. This formula is wrong.
Option a, is the correct answer.
Answer: A. Paul's argument is correct; Manuel used the incorrect formula to find the volume of square pyramid X.
