Answer:
C
Step-by-step explanation:
29 = 7y -4 +y+6
29 = 8y+2
8y = 27
y = 27/8
y =. 3.375
The midpoint of a line is the middle of the distance between two points. The value of y if is the midpoint of AC is 3.375
Midpoint of a segmentThe midpoint of a line is the middle of the distance between two points. Given the following parameters
MN = 7y - 4, and;
NP= y + 6
MP = 29
If N is between M and P. hence;
MN + NP = MP
Substitute
7y-4 + y + 6 = 29
8y + 2 = 29
8y = 27
y = 27/8
y = 3.375
Hence the value of y if N is between M and P is 3.375

What is the m < FAB?
Answer:
∠ FAB = 75°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ FAB is an external angle, thus
13x - 3 = 3x + 2 + 55 = 3x + 57 ( subtract 3x from both sides )
10x - 3 = 57 ( add 3 to both sides )
10x = 60 ( divide both sides by 10 )
x = 6
Thus
∠ FAB = 13x - 3 = 13(6) - 3 = 78 - 3 = 75°
PLEASE HELP!!! The figure shown below is a square. Give the angle value (numerical, not the letters)
Answer:
45
Step-by-step explanation:
if it is a square then all angles are 90 degrees. the line halfs them all meaning 90/2=45
Answer:
Step-by-step explanation:
Diagonals of square bisect the angles ∠D,∠E, ∠F & ∠G
And we know ∠D = 90

what is 16-2t=5t+9
Answer:
t = 1
Step-by-step explanation:
16 - 2t = 5t + 9
1) First move 5t to the left side
16 - 2t - 5t = 9
2) Then move 16 over to the right side
-2t -5t = 9 - 16
3) simplify both sides
-7t = -7
4) divide both sides by 7
-t = -1
5) divide both sides by -1
t = 1

For any nonnegative real number a, (√a)^2 = ____.
A. √a
В. а
C. 1
D. a^2
Answer:
B
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] = [tex]a^{\frac{1}{2} }[/tex]
Thus
([tex]\sqrt{a}[/tex] )² = [tex]a^{\frac{1}{2} }[/tex] × [tex]a^{\frac{1}{2} }[/tex] = [tex]a^{(\frac{1}{2}+\frac{1}{2}) }[/tex] = [tex]a^{1}[/tex] = a → B
Please tell me which option it is !?!?
Answer:
it is the second option. answer is x[tex]\leq[/tex]-8/3 or x>4
Step-by-step explanation:
we have the inequality 3x+8/x-4=0
we first multiply both sides by 4 the 4 cancels out on the left-hand side and 4*0 is 0 so we now have 3x+8=0 then we subtract both sides by 8 and get 3x=-8 then we divide both sides by 3 and get x=-8/3
x[tex]\leq[/tex]-8/3 works in the original inequality
-8/3[tex]\leq[/tex]x[tex]\leq[/tex]4 does not work
x>4 does work
Answer:
its the first one I promise I even used a special calculator to be sure it is 100% the first option trust me
Order the cones from least volume to greatest volume
Cone A r=5 inches h=6 inches
Cone B r= 7 inches h=4 inches
Cone C r=6 inches h=5 inches
Answer:
Cone A, Cone C, Cone B
Step-by-step explanation:
The volume of a cone is V=πr^2h/3 where V represents the volume, r represents the radius, and h represents the height.
That means the volume of cone A would be:
V = π * 5^2 * 6/3
V = π * 25 * 2
V = 50π
And the volume of Cone B would be:
V = π * 7^2 * 4/3
V = π * 49 * 4/3
V = 65.33π (about)
Lastly, the volume of Cone C would be:
V = π * 6^2 * 5/3
V = π * 36 * 5/3
V = 60π
65.33π > 60π > 50π
Therefore, Cone B has the largest volume, then Cone C, and, lastly, Cone A.
Suppose you will perform a test to determine whether there is sufficient evidence to support a
claim of a linear correlation between two variables. Find the critical values of r given the
number of pairs of data n and the significance level a.
n=12. a.= 0.01
Answer:
The critical values of r are -0.708 and 0.708.
Step-by-step explanation:
A statistical test is being performed to determine whether there is any linear correlation between two variables.
The hypothesis can be defined as follows:
H₀: There is no linear correlation between two variables, i.e. ρ = 0.
Hₐ: There is a significant linear correlation between two variables, i.e. ρ ≠ 0.
The test statistic is given as follows:
[tex]t = \frac{r\sqrt{n-2}}{\sqrt{1-r^{2}}}[/tex]
The degrees of freedom of the test is:
[tex]\text{df}=n-2=12-2=10[/tex]
The significance level of the test is, α = 0.01.
The critical values of r are:
[tex]r_{\alpha/2, (n-2)}=r_{0.01/2, (12-2)}=r_{0.005, 10}=\pm0.708[/tex]
*Use the r critical value table.
Thus, the critical values of r are -0.708 and 0.708.
From the 'r' table, the values of 'r' are -0.708 and 0.708.and this can be determined by using the hypothesis test.
Given :
Suppose you will perform a test to determine whether there is sufficient evidence to support the claim of a linear correlation between two variables.Number of pairs of data n and the significance level a is n = 12, a = 0.01.The hypothesis test is performed in this problem. The null and alternate hypothesis is:
[tex]\rm H_0 : p=0\\[/tex]
[tex]\rm H_1:p\neq 0[/tex]
The t-statistics is given by:
[tex]\rm t =\dfrac{r\sqrt{n-2} }{\sqrt{1-r^2} }[/tex]
Degree of freedom is given by:
df = n - 2 = 12 - 2 = 10
The significance level for this test is [tex]\alpha = 0.01[/tex]
Now, the critical value r is given by:
[tex]\rm r_{\alpha /2,(n-2)}=r_{0.01/2,(12-2)}=r_{0.005,10} = \pm0.708[/tex]
So, from the 'r' table, the values of 'r' are -0.708 and 0.708.

Solve systems of equations for x + y, please!! 12x - 8y = -12 6x + 4y = -30
Answer:
x = -3, and y = -3, or the ordered pair is (-3, -3)
Step-by-step explanation
To solve this system, you can use the elimination method:
First, write both equations down.
12x - 8y = -12
6x + 4y = -30
If you multiply the second equation by 2, you can eliminate x. Rewrite the first equation, and multiply the second one by 2:
12x - 8y = -12
12x + 8y = -60
Once added, you get the equation:
24x = -72
x = -3
Now, we just plug -3 into one of the equations and solve for y:
12x - 8y = -12
12(-3) - 8y = -12
-36 - 8y = -12
-8y = 24
y = -3
So, x=-3, and y=-3, or the ordered pair is (-3, -3)
Arthur is organising his collection of DVDs. He has 112 altogether.
The ratio of comedy films to
action to horror is 6 : 7 : 3
How many of each type of DVD does he have?
Comedy
Action
Horror
Answer:
42 Comedy, 49 Action, 21 Horror
Step-by-step explanation:
6 comedy : 7 action : 3 horror = 16 parts or if you think of it as a fraction, 16 is the denominator and the numbers for each ratios are the numerators
112 (the total)/16 = 7 movies per part
6 parts of comedy = 6 x 7 = 42
7 parts action = 7 x 7 =49
3 parts horror = 3 x 7 = 21
Another way to think of it is:
(ex. comedy)
6/16=x/112
(CROSS MULTIPLY HERE)
16x=672
x=42

Bryce did chores every single day in september.It took Bryce 7/8 hours to completing his chores on 20 of the days.The remaining days of the month it took him 1 hours to complete his chores.How many hours did Bryce do chores in September?(there are 30 days in September). ANSWER STEP BY STEP. PLZZZ ANSWER I REALLY NEED HELP
Answer:
Step-by-step explanation:
Because Bryce did 7/8 hours every day for 20 days,
7/8 hours is 52.5 minutes.
so then times 20, you will get 1050 minutes.
Then divided by 60(minutes per hour) you will get 17.5 hours,
which means she did 17 hours and 30 minutes in the first 20 days,
then you plus the last 1 hour per day for 10 days,
you will get 10 hours plus 17 hours and 30 minutes.
So Bryce have worked 27 and 30 minutes in september.
(I wish this could help you)
Answer:
27.5 hours
Step-by-step explanation:
Total hours:
20*7/8 + 10*1= 35/2+10=17.5+10= 27.5 hours

= 166 grams of salt
This is because you already solved how much one of each container would be in the last question (question 3), so you would just have to multiply it my 2 to get the answer.

Answer:
1. 50
2. 12
Step-by-step explanation:
Answer:
2. 50 stamps
3. 12 minutes
Step-by-step explanation:
2. Darius had 15 stamps, then he ordered 3 rolls. You can determine how many he got from the rolls by subtracting the total from 15. 165 - 15 = 150.
Now we know that there were 150 stamps in the rolls Darius ordered. Divide 150 by 3 (3 rolls) to find the number of stamps in each roll!
150/3 = 50.
3. First, remember that 1 hour = 60 minutes.
We want to find how long America played soccer on Monday, which is the same amount of time she played on Tuesday and Wednesday as well. This means we can subtract Thursday and Friday's time from 60 minutes, then divide that time by 3, to find the time she played on Monday.
60 - 14 - 10
= 36 minutes
Now, we divide 36 minutes by 3 to get 12 minutes.
