5x² = 80 in a quadratic equation
Please help I have 15 minutes!!!!!
Show me how to find x using the correct equation shown here (geometry)
Step-by-step explanation:
8x - 17° = 5x + 19° ( being corresponding angles)
8x - 5x = 19° + 17°
3x = 36°
x = 12°
Hope it will help :)❤

If Angle 2 is 60. Find angle 8
options:
140
100
40
60
If Angle 4 is 40 degrees. Find Angle 1.
Options
140
100
40
60
Answer:
60,140
Step-by-step explanation:
alternate interior angles are congruent. and then 1 and 4 are supplementary angles which create 180
Answer:
Angle 2 is 60. Find angle 8
solution,
2=8(being co-alternate angle)
60=8
so, 8=60,,
If Angle 4 is 40 degrees. Find Angle 1
solution,
again,
let 1 be x
4+x=180
40°+x=180
x=180-40
x=140,,
therefore x=140,,

The Pythagorean Theorem says that in a right triangle, [tex](\text{leg})^2+(\text{leg})^2=(\text{hypotenuse})^2[/tex], so in this triangle, the legs are 5 and a; the hypotenuse is 13.
[tex]5^2+a^2=13^2\\25+a^2=169\\a^2=144\\a=\sqrt{144}\\a=12[/tex]
DOES ANYONE KNOW HOW TO DO THESE???
Answer:
Step-by-step explanation:
7. The horizontal translation is 3 units to the right, this is determined by the value that is being added or subtracted to x directly. In this case, x is being subtracted by 3 meaning that it is translated 3 units to the right.
8. It is being translated 2 units up. This is determined by the number that is added to the quadratic equation. In this case, it is increased by 2 which means an upward translation. If it was being subtracted it would be a downward translation.
9. Yes, when a quadratic equation has a negative sign outside of it which changes its values it means that it is being reflected.

The volume of this cylinder is approximately 416,992 cubic inches.
The height is ___ inches.
Use ≈ 3.14.
Answer:
83
Step-by-step explanation:
height = [tex]\frac{volume}{\pi *r^{2} }[/tex]
height = [tex]\frac{416992}{3.14*(40)^{2} }[/tex]
height = 83
Answer:
Step-by-step explanation:
V = pi * r^2 * h
V = 416992
r = 40 inches.
pi = 3.14
416992 = 3.14 * 40^2 * h
416992 = 3.14 * 1600 * h
416992 = 5024 * h
416992 / 5024 = h
h = 83

If 50 grams of sweats cost $2.10,find the cost of 380 of sweats,giving your answer correct to the nearest 5 cent
Answer:
$15.95
Step-by-step explanation:
cost of 1 gram of sweet = $2.10 / 50 = 0.042
Cost of 380 g = 380 x 0.042 = $15.96
to the nearest 5 cent = 15.95

Guys please help on this I barely understand it
the answer is 56 degrees
looking at the triangle you can identify it as a right triangle by the square at the top right corner. all right triangles have at least one 90 degree angle, which is what that square marks. the question also gives you the measurement of the second angle wich is 34 degrees. all angles of a triangle have to add up to 180 degrees, so we can add 90 degrees and 34 degrees wich gives us the sum of 124. now if you subtract 124 from 180 you get 56, therefore, the angle x is 56 degrees.
Given:BK=CH Which additional congruence statement could you use to prove that ∆BJK ≅ ∆CFH by the HL Theorem?
Answer:
B
Step-by-step explanation:
The hl theorem says that if we have two right triangles that have a congruent hypotenuse and a congruent leg, the two triangles are congruent
in this case the exercise says the two leg are congruent, so we have to say that the two hypotenuse are congruent
So
JB congruent to FC
