Answer:
9
Step-by-step explanation:
Since it is a straight line, therefore it will always be 180°
So...
(8v +3) +105 = 180
8v + 3 + 105 = 180
8v = 180 - 108
V = 72/8
= 9
Answer:
[tex]\boxed {\boxed {\sf v=9}}[/tex]
Step-by-step explanation:
In the diagram, there are 2 angles: 105° and (8v+3)°. They are on a straight line together, so they are supplementary angles. They must add to 180 degrees. We can set up an equation.
[tex]105 + (8v+3) = 180[/tex]
We are solving for v, so we must isolate the variable. First, we can rearrange the right side and combine the like terms (the constants without a variable).
[tex]105 +8v+3= 180 \\8v + (105+3) = 180 \\8v + 108= 180[/tex]
108 is being added to 8v. The inverse operation of addition is subtraction. Subtract 108 from both sides of the equation.
[tex]8v+108-108= 180-108 \\8v= 180-108 \\8v=72[/tex]
v is being multiplied by 8. The inverse operation of multiplication is division. Divide both sides by 8.
[tex]\frac {8v}{8}= \frac{72}{8}\\[/tex]
[tex]v= \frac{72}{8}[/tex]
[tex]v=9[/tex]
v is equal to 9.

Step-by-step explanation:
1 corn equals 700-800 the yellow tiny thing.
so, lets just assume it has 700,
therefore, 700 - 6 = 694
694 + 1 = 695.
or 700 + 1 = 701.
or perhaps
800 - 6 = 794
794 + 1 = 795
or 800 + 1 = 801
but then again it depends on how much the yellow tiny thing is on the corn. bc, it could be 705, 807, or even 900, who knows.

Find cos(x) if [tex]\frac{sin^2x-1}{cosx} =-1[/tex].
A -1
B 2
C 1
D 0
Answers
(sin²(x) - 1)/cos(x) = -1
-cos²(x)/cos(x) = -1
-cos²(x) = -cos(x)
cos²(x) - cos(x) = 0
cos(x) (cos(x) - 1) = 0
Then it follows that cos(x) = 0 or cos(x) = 1. But if cos(x) = 0, then the original expression on the left side of the equation would be undefined. Then C is the only valid solution.

Answers
9514 1404 393
Answer:
C. (x -1)/(x +7)
Step-by-step explanation:
The factor (x +1) in the numerator cancels the same factor in the denominator, leaving the ratio (x -1)/(x +7). This matches choice C.
_____
Additional comment
Even though (x+1)/(x+1) = 1 and can be removed from the expression, the fact that it is undefined at x=-1 means the reduced ratio (x-1)/(x+7) is only a valid representation of the original ratio when x≠-1. The factor (x+1) may be gone, but the domain restriction associated with it remains.
if angle 1 and angle 2 are vertical angles, angle 2 and angle 3 are complementary angles and the measure of angle 3 is 56 degrees find measure of angle 1
Answers
Answer:
34º
Step-by-step explanation: so basically you know a complementary angle is 2 angles that make a straight line and a vertical angle crosses which means 2 angles are congruent to each other so I drew a line that bisected the angle by drawing a line that cut through the right angle and i extended a line down from the right angle so now I have a vertical angle and a complementary so from here I labeled each angle <1 <2 <3 If I know angle 3 is 56º then I know 56 plus __ equals 90º I then subtracted 56 from 90 and I got 34 and since I am trying to figure out what angle 1 is I know that angle 1 and 2 are vertical angles therefore I know they are congruent to each other so <1 = 34º

The volume of a crate with length of x feet, width of 8 - x feet, and a height of x - 3 feet is given by V(x)=x(8−x)(x−3) find the maximum volume of the crate and the dimensions for this volume
Answers
Therefore, the dimensions for the maximum volume are x=8 and x=-3.
Now we can solve for the actual maximum volume:
V max =(8)(8)-(3)(8)=64.
The maximum volume is 64 cubic feet and the dimensions for this volume are 8x=-3

Also:
[tex]b + 15 = 40[/tex]
So:
[tex]b = 25[/tex]
The value of (d) will be calculated using Pythagoras theorem.

Answer:
JH = 15
Step-by-step explanation:
KJ = 10
KI = 14
IH = 11
JH = ?
In order to find JH, we need to find JI, then add it to IH, which is 11. Here's the equation:
JH = JI + 11
In order to find JI, we need to subtract KJ from KI. Here's the equation:
14(KI) - 10(KJ) = JI
14 - 10 = 4
JI = 4
Now we plug in the numbers from our first equation:
JH = JI + 11
JH = 4 + 11
JH = 15
Answer:
JH= 15Step-by-step explanation:
Let KJ= 10, KI= 14, and IH= 11KI - KJ = J14 - 10 = 4J + IH = JH4 + 11 = 15[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]

Two clocks are set at 6 A.M. One clock gains 30 seconds every hour and the second clock
loses 1 minute every hour. At what time will the faster clock be 30 minutes ahead of the
second clock?
Answers
Difference in time of both the clocks after 1 minute will be the sum of gain in time of one clock and delay in time of the second clock in 1 minute.
First clock will be 30 minutes ahead of the second clock in 20 hours.
It's given in the question,
Both the clocks are set at 6 A.M.First clock gains 30 seconds every hourSince, 1 second = [tex]\frac{1}{60}[/tex] minutes
Therefore, 30 seconds = [tex]\frac{30}{60}[/tex] minutes
= 0.5 minutes
That means first clocks gains 0.5 minutes in every hour.
Second clock loses 1 minute every hourTherefore, difference in both the clocks in every hour = 1 + 0.5
= 1.5 minutes
Difference of 30 minutes will be in the duration = [tex]\frac{30}{1.5}[/tex] hours
= 20 hours
First clock will be 30 minutes ahead of the second clock in 20 hours.
