Answer:

a) 5/7 b) 12/8, 1 4/8

Step-by-step explanation:

Answer:

a) 5/7

b) 2/3

c) 1/6

Step-by-step explanation:

a) 2/7 + 3/7

since the denominators are both 7 we use 7 as the LCM ( lowest common multiple)

2+3/7 = 5/7

b) 5+7/8 = 12/8. 4 can go into both numbers so it gives 3/2

c) 2/3 - 1/2 multiply the denominator since they are different (3×2) =6

4-3/6 = 1/6

Step-by-step explanation:

In 1 day we have daytime and night time each 12 hrs

in the day time he climbs 5ft and at night he slips 2 ft

meaning he climbs a total of 3ft(5-2) each day

ANSWER IS C= 1/4X^2-x+4

Step-by-step explanation:

The solving is pretty easy but i like to go on "m a t h w a y" for the original equation that the problem is asking, and then find the answer on

"m a t h w a y" And then type in the other equation choices (a,b,c,d) and find which one has the same graph or same vertex and stuff!

Answer:

B

[tex] \frac{1}{4} {x}^{2} - 4x + 7[/tex]

Step-by-step explanation:

f(×) = 1/4 (x- 2)^2 + 3

= 1/4 ( x^2 -2x -2x +4) +3

=1/4 x^2 -4x +4 +3

=1/4 x^2 -4x +7

Answer:

0.5

Step-by-step explanation:

AB and AC are tangents from point A to the circle with center P at points B and C respectively.

Measures of the tangents drawn from external points to a circle are equal.

Therefore,

11y = 3y + 4

11y - 3y = 4

8y = 4

y = 4/8

y = 0.5

Answer:

im pretty sure it'd be 76 weeks!

Step-by-step explanation:

one water tank holds 1216 and loses 5 gallons/week

another water tank holds 1520 gallons and loses 9 gallons/week

youd make an equation:

1216-5x=1520-9x

(each side being the amount of water the tank can hold minus the amount it loses per week [x])

heres how you execute the equation:

1216-5x=1520-9x

-5x=1520-1216-9x

-5x=304-9x

-5x+9x=304

4x=304

x=304/4

76

after you do the equation, you get x=76, meaning 76 weeks! :-)

Answer:

Option A and C

Step-by-step explanation:

Explanation for why I choose option A :-

If you look at the triangle, HK has a midpoint of point L, HJ has a midpoint of point M, and KJ has a midpoint of point N. Now if you stretch the lines inside of the triangle, they intersect at point P which is known as the circumcenter of HJK, true.

Explanation for why I choose option C :-

Now let us look at the lines stretch inside of the triangle. There are three lines which are congruent. Those lines are PK, HP, and PJ (they are the big lines inside the triangle) are congruent. Since those three line intersect at point P, it make the statement true that P is the circumcenter of HJK.

We do not know the third line (PN) measurements to find that if the three lines (PL, PM, and PN) are congruent and equal 90⁰. Since we do not know, it would not prove that they are congruent and P is the circumcenter of HJK.

Well it says that triangle HJK is an acute triangle which is true, but this doesn't prove that P is the circumcenter of HJK.

I hope this helps, thank you :) !!

The required conditions are L, M, N are the midpoints of [tex]\overline{HK}, \overline{HJ}, \overline{KJ}[/tex] and [tex]\overline{PK}\cong \overline{HP}\cong \overline{PJ}[/tex]. So, options A and C are correct.

Given:

The given figure of a triangle HJK.

To find:

The conditions that would be enough to prove that P is the circumcenter of HJK.

Explanation:

The circumcenter of a triangle is the intersection of perpendicular bisectors and it is equidistant from each vertex of the triangle.

P is the circumcenter of triangle HJK if PL, PM, PN are perpendicular bisectors and P is equidistant from vertices H, J, K.

PL, PM, PN are perpendicular bisectors if L, M, N are the midpoints of [tex]\overline{HK}, \overline{HJ}, \overline{KJ}[/tex].

P is equidistant from vertices H, J, K if [tex]\overline{PK}\cong \overline{HP}\cong \overline{PJ}[/tex].

The required conditions are L, M, N are the midpoints of [tex]\overline{HK}, \overline{HJ}, \overline{KJ}[/tex] and [tex]\overline{PK}\cong \overline{HP}\cong \overline{PJ}[/tex]. So, options A and C are correct, and other two options are incorrect.

Answer:

Step-by-step explanation:

Hey There!

This is an example of a 45-45-90 special right triangle

We know this because one of the angles is 45 and the other is 90

to get the missing angle we subtract the given angles by 180

180-90-45=45 indicating that this is a 45-45-90 triangle

Given the hypotenuse we have to find the two legs

Remember the hypotenuse of a 45-45-90 triangle is [tex]x\sqrt{2}[/tex]

x being equal to one of the legs

so to get x we divide [tex]4\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex]

[tex]\frac{4\sqrt{2} }{\sqrt{2} } =4[/tex]

so we can conclude that the two legs =4

Answer:

115.02 feet

Step-by-step explanation:

The angle of depression from an air traffic control tower to an airplane on the runway is 72 degrees. If the tower is 354 feet tall, how far is the airplane from the base of the tower?

We solve this question using the Trigonometric function of tan

tan x = Opposite/Adjacent

x = Angle of depression = 72°

Opposite = Height of the tower = 354 feet

Adjacent = Distance of the airplane from the base of the tower = y

Hence,

tan 72 = 354/y

Cross Multiply

tan 72 × y = 354

y = 354/tan 72

y = 115.02157247 feet

Approximately = 115.02 feet

Therefore, the distance of the airplane from the base of the tower is 115.02 feet

Answer:

A- the slope is 2/3 and the y-intercept is -2

Step-by-step explanation:

We can find the slope using this formula- y=mx+b

so, for this it looks like the y-intercept(the part of the line on the y-axis) is -2

The slop can be found by picking two points, in this case I will pick

(0,-2)(x1,y1) and (3,0)(x2,y2)

Now, you can divide [tex]\frac{y2-y1}{x2-x1}[/tex]

so, it would be 0-(-2)/3-0= 2/3

So your slope is 2/3 and your y-intercept is -2
